4. As people become more concentrated in cities, some pressure on ecosystems in areas that are not less populated eases. Why do you think this is the case?

Answers

Answer 1

The main factors that led to a boom in human population size in the last 300 years include advancements in medical technology, increased agricultural productivity, industrialization, and improved standards of living. Population A would increase by more people in one year due to its higher growth rate. The relationship between population density and population distribution is that population density is a measure of the number of people living per unit area, while distribution refers to the pattern of where people live. Urbanization relieves some pressure on ecosystems as it concentrates human impact into smaller areas, allowing the regeneration of ecosystems in non-urbanized regions.

Historically, the human population grew at a slow rate until the onset of the Industrial Revolution, which led to improved medicine, sanitation, and food production, promoting a rapid increase in population. Population A's annual growth rate of 3.3 percent would result in a larger absolute increase in numbers compared to Population B with an annual growth rate of 1.8 percent, despite the initial population size difference. The concept of population density is distinct from distribution; densely populated areas might be unevenly distributed if large regions are sparsely inhabited. Urbanization can reduce pressure on ecosystems located away from cities because it centralizes resource consumption and waste production, allowing undisturbed regions to maintain or recover their natural ecological functions.

The best estimate for the amount of Earth's primary production occurring in the oceans is around 50%, as oceans and terrestrial systems have similar levels of production, with the half of the biosphere's energy captured by oceanic phytoplankton.

The question concerns the estimate of Earth's primary production coming from the oceans. Based on the information provided, approximately half of the energy that flows through the Earth's biosphere is captured by phytoplankton in the ocean. Moreover, marine productivity is almost the same as that of terrestrial systems, with marine net production being about 35-50 billion metric tons per year, compared to terrestrial production which reaches 50-70 billion tons per year. Therefore, the best estimate for the fraction of Earth's primary production that occurs in the oceans would be around 50%.

Answers

Answer:

a. a portion of the population becomes isolated from the remainder of the population and experiences different selective pressures

Explanation:

This is an example of allopatric speciation Allopatric speciation is a form of speciation (formation of new species) that occurs as a result of geographic isolation. This means that a part of population becomes physically separated from the initial main population. There is no gene flow between these two populations and as a result the two populations  reach a high level  of genetic divergence. They can no longer interbreed which means they become two different species (speciation).

New populations evolve as result of mutation, genetic drift and natural selection.

For example, Galapagos finches are isolated from others by the ocean (geographic isolation).  Because of the isolation, the finches don’t breed with one another. So, they developed unique characteristics and became endemic.

Which word describes structures that are used for the same purpose in the environment but do not share the same development?

Answers

Answer:

Convergent evolution is the independent evolution of similar features in species of different lineages. Convergent evolution creates analogous structures that have similar form or function but were not present in the last common ancestor of those groups. The cladistic term for the same phenomenon is homoplasy. The recurrent evolution of flight is a classic example, as flying insects, birds, pterosaurs, and bats have independently evolved the useful capacity of flight. Functionally similar features that have arisen through convergent evolution are analogous, whereas homologous structures or traits have a common origin but can have dissimilar functions. Bird, bat, and pterosaur wings are analogous structures, but their forelimbs are homologous, sharing an ancestral state despite serving different functions.

The opposite of convergence is divergent evolution, where related species evolve different traits. Convergent evolution is similar to parallel evolution, which occurs when two independent species evolve in the same direction and thus independently acquire similar characteristics; for instance, gliding frogs have evolved in parallel from multiple types of tree frog.

Many instances of convergent evolution are known in plants, including the repeated development of C4 photosynthesis, seed dispersal by fleshy fruits adapted to be eaten by animals, and carnivory.

What did matthias schleiden contribute to the cell theory

Answers

Answer:

He was the firs who claimed that organism is composed of cells.

Explanation:

Together with Theodor Schwann and Rudolf Virchow, a German botanist Matthias Schleiden was a cofounder of cell theory. He studied plant structure under the microscope and there he discovered that the basic units of plant organism are cells. He was also involved in the findings about the cell nucleus and the cell division process.

Final answer:

Matthias Schleiden, a German botanist, contributed significantly to the development of the cell theory. He proposed, with Theodor Schwann, that all living things are composed of one or more cells, the cell is the basic unit of life, and new cells come from existing cells. His work aided in the acceptance of cell theory as a foundation for biological understanding.

Explanation:

The German botanist Matthias Schleiden contributed significantly to the development of the cell theory. Along with the zoologist Theodor Schwann, he proposed in the late 1830s the unified cell theory. This theory posited that all living things are made up of one or more cells, the cell is the basic unit of life, and new cells come from existing cells.

Schleiden made extensive microscopic observations of plant tissues and described them as being composed of cells. His studies of plant cells were particularly impactful because plant cells, with their visible, thick cell walls, were easier to observe than animal cells. Contrary to the contemporary belief, Schleiden put forth that cells did not form through crystallization, but rather through cell division.

Despite the fact cells were first observed in the 1660s by Robert Hooke, Schleiden's work, alongside collectives efforts of scientists like Schwann, Remak, and Virchow, was instrumental in the scientific community's acceptance of the cell theory as a foundation for understanding the basic structure of life.

Which of the following parts of a nervous reflex arc is usually a muscle or gland? a) Sensory receptor b) Sensory neuron c) Motor neuron d) Effector e) Integration Center

Answers

the answer is d) effector

Final answer:

The effector, which is usually a muscle or a gland, is the part of the nervous reflex arc that responds to signals transmitted through the motor neuron, or the efferent branch, of the reflex arc. This reaction accomplishes the intent of the reflex, often leading to a muscular movement or glandular secretion. Both short and long reflex arcs can involve the efferent branch.

Explanation:

In the nervous reflex arc, the part that is usually a muscle or gland is the Effector (d). The effector responds to the signal it receives via the motor neuron or the 'efferent branch' of the reflex arc. This branch starts at a central neuron and proceeds along the preganglionic fiber, making a synapse with a ganglionic neuron which then projects to the target effector, causing it to react.

The efferent branch of the reflex arc can be involved in both short and long reflexes. In case of a long reflex, the sensory neuron sends its signal to the central nervous system (CNS) while in a short reflex, the sensory neuron bypasses the CNS and directly activates the ganglionic neuron, leading to a quicker response at the effector.

These reflexes are coordinated via pathways which include sensory receptors, sensory neurons, an integration center, a motor neuron, and the effector. The sensory receptors are responsible for recognizing a change in the environment, the sensory neurons relay this information to an integration center in the CNS, which interprets this information and then sends a signal to the motor neuron. This signal is received and acted upon by the effector - our muscles or glands.

The amniote egg solved what amphibian problem by _________

Answers

Answer:

The amniote egg prevented the drying of the egg

Explanation:

The first fully terrestrial vertebrates (adapted to land) were amniotes meaning that they produce eggs with internal membranes that enable embryo breathing without drying out (gases could pass through, but not the water).

For example, amphibians were the first animals on the land, but they had to return to water to reproduce, because they lack amniotic egg

So, amniote egg is adaptation that helped animals colonize dry land.

Final answer:

The amniotic egg, characteristic of amniotes including reptiles, birds, and mammals, solved a crucial amphibian problem by allowing for terrestrial reproduction and less dependence on a watery environment for development. The evolution of the amniotic egg enabled these creatures to explore and inhabit wider terrestrial ecosystems.

Explanation:

The amniote egg, a key characteristic of amniotes which include reptiles, birds, and mammals, solved a major amphibian problem by allowing for terrestrial reproduction and less dependence on water for development. Before the evolution of the amniotic egg, amphibians' shell-less eggs restricted them to moist environments. However, the amniotic egg, with its four extra-embryonic membranes and protective shell, provided an internal aquatic environment for the embryo, permitted gas exchange, and sequestered waste, insulating the organism from desiccation and enabling them to branch out into drier environments.

These eggs are terrestrially adapted and the albumin within them provides the embryo with water and protein. At the same time, the yolk sac, another extraembryonic membrane contained within the egg, provides nutrients to the developing embryo. This was a significant development as it allowed amniotes to explore and populate wider ecosystems, marking a major evolutionary transition from water to land.

The amphibian problem solved by the amniotic egg was, therefore, dependence on a water environment for reproduction and development. With the evolutionary advent of the amniotic egg, embryos could now develop in a variety of terrestrial conditions.

Pancreatic digestive juices are carried by

Answers

Answer:

The pancreatic duct

Explanation:

Pancreatic digestive juices, consisting of enzymes and bicarbonate, are carried to the small intestine via the primary pancreatic duct and the accessory duct, assisting digestion.

Pancreatic digestive juices, which contain a mix of enzymes and bicarbonate, are essential for digestion in the small intestine. These juices are produced by the exocrine cells of the pancreas and travel through the pancreatic ducts to reach their destination.

The main pancreatic duct joins with the common bile duct to form the hepatopancreatic ampulla, which controls the release of both pancreatic juice and bile into the duodenum.

Additionally, there is a secondary duct known as the accessory duct, or duct of Santorini, which may directly connect the pancreas to the duodenum.

The mechanism of water reabsorption by the renal tubules is ________.

Answers

Answer: The correct answer is OSMOSIS.

Explanation:

The option attached to this question are as follows:

A. Filtration.

B. Osmosis.

C. Active transport.

D. Co-transport with sodium ion.

Water re-absorption is the process by which water, which was lost during glomerular filtration re-enter the blood. The process typically occurs at the proximal convoluted tubule of the nephron. The process occurs by mean of osmosis, which is a form of passive transport. Re-abosorption usually occur based on the concentration gradients that exist in the convoluted tubule, movement takes place from the high concentration in the tubule to the low concentration in the blood capillaries that are surrounding the tubules.

Final answer:

Water reabsorption in the renal tubules occurs through active transport and osmosis, regulated by hormones like ADH.

Explanation:

Tubular reabsorption is the process by which water is reabsorbed from the renal tubules in the kidneys. Water reabsorption occurs mainly in the proximal convoluted tubule (PCT) and is regulated by various factors, including hormones like antidiuretic hormone (ADH). Sodium ions are actively transported out of the tubule, creating an osmotic gradient that causes water to follow and be reabsorbed into the peritubular capillaries. This mechanism helps maintain water balance in the body.

Offshore wind turbines are more efficient compared to onland wind turbines. Which statement best describes the advantage of using offshore wind turbines than onland wind turbines?

C) Offshore wind turbines contributes to carbon emissions compared to onland wind power turbines.
D) Offshore wind turbines have more consistent wind power and speed compared to onland wind turbines.

Answers

Answer D: Offshore wind turbines have more consistent wind power and speed compared to on land wind turbines.  

Explanation:  

Offshore wind turbines do not need land space. There are no trees that would interfere with the wind power and speed. Offshore wind turbines do not use water.

Offshore wind turbines are more advantageous because they have access to more consistent and stronger winds, potentially generating more energy. Hence, option D is correct.

Offshore turbines can utilize the steadier and stronger winds found over bodies of water, and because they are usually located far from shore, they are less likely to conflict with land-based uses and aesthetic concerns. Moreover, they have the potential to generate more energy due to these stronger and more consistent winds.

Phases in interphase:

G1 or Gap 1 is characterized by cell growth (cell becomes much larger), synthesis of molecules and organelles copying.S phase is characterized by DNA replicationG2 phase or Gap 2 phase is phase in which cell makes more proteins and organelles and prepares for mitosis
Final answer:

The G1 phase is a cell's first growth stage where it performs normal functions and prepares for DNA replication. Following this, the cell enters G2 phase, which entails further growth, protein synthesis for chromosome manipulation, and preparation for mitosis.

Explanation:

The G₁ phase (gap 1 phase) is the first gap, or growth stage, in a cell's life cycle. During this phase, a cell grows and carries out all its normal metabolic functions and processes. It's a time when the cell might spend from a few hours to many days, depending on its specific role and the physical conditions. For cells that will divide again, G₁ is followed by replication of the DNA during the S phase.

Following DNA replication during the S phase, the cell enters the G2 phase. This is a second gap phase, during which the cell continues to grow. It also makes the necessary preparations for mitosis, which includes synthesizing proteins necessary for chromosome manipulation and duplicating some cell organelles. The length of this phase is typically about 5 hours.

•C. disorder can be stopped and from that order just happens.
•D. a form of matter is required to make things orderly again.

Answers

Answer:

•B. a form of energy is required to be input so it can become orderly again

Explanation:

Order can be restored from a disordered system by inputing energy. The energy helps restore back the orderliness in a system.

We know that entropy is the state of randomness or disorderliness of the particles of a system. Entropy increases with rise in temperature. When the heat energy that causes temperature rise is removed from a system, the kinetic energy require for molecules to move is reduced and orderliness can gradually be approached.

For example, heating of water causes agitation of its molecules. The randomness of it particles increases. This is seen in the phase change from liquid to gases. As temperature is lowered, the water cools and orderliness is approached again. We can approach more orderliness by putting the water in a refrigerator.

In some systems, we can bring gases into a more ordered state by compression. The pressure applied to compress gases is a form of energy because work is done to bring the molecules into close contact as seen in a gas cylinder.

Sickle-cell disease is an autosomal recessive disorder that causes the red blood cells of an affected person to be rigid and abnormally shaped. The life expectancy of a person affected by the disorder is approximately 45 years. Carriers of the disease produce some sickled cells, but not enough to be symptomatic.


Malaria is a potentially fatal disease caused by the protist Plasmodium falciparum.


Studies have shown that those affected by sickle-cell disease (genotype ss), as well as carriers who possess only one sickle-cell allele (Ss), are much more resistant to malaria than those with homozygous dominant genotypes (SS). This resistance is created in part by the rupturing of any sickled red blood cells that are infected with the parasite, preventing Plasmodium falciparum from reproducing and making it more susceptible to the host's immune system.


Which of the following statements best predicts what would happen in response to a prolonged epidemic of malaria in a population with no previous exposure to malaria?


A. The frequency of the homozygous recessive genotype (ss) would decrease.

B. The frequency of the dominant allele (S) would increase.

C. The frequency of the sickle-cell allele (s) would increase.

D. The frequency of the homozygous dominant genotype (SS) would increase.

Answers

Explanation:

Sickle cell disease is a group of disorders that affects hemoglobin, the molecule in red blood cells that delivers oxygen to cells throughout the body. People with this disorder have atypical hemoglobin molecules called hemoglobin S, which can distort red blood cells into a sickle, or crescent, shape.

Signs and symptoms of sickle cell disease usually begin in early childhood. Characteristic features of this disorder include a low number of red blood cells (anemia), repeated infections, and periodic episodes of pain. The severity of symptoms varies from person to person. Some people have mild symptoms, while others are frequently hospitalized for more serious complications.

The signs and symptoms of sickle cell disease are caused by the sickling of red blood cells. When red blood cells sickle, they break down prematurely, which can lead to anemia. Anemia can cause shortness of breath, fatigue, and delayed growth and development in children.
