Answer:

Wildfire

Explanation:

The wildfires are one very devastating occurrence that can appear both naturally and be caused by humans. Naturally these fires occur because of high temperatures and drought, and because of thunders. When they occur, they spread out very quickly and it is an uncontrolled fire. It manages to burn down very large areas of grasslands or forests, moving very quickly and being extremely difficult to put it under control. While the wildfires are very destructive, there's also a positive from them, as they leave behind lot of ashes, and the ashes fertilize the soil, providing the basis for the growth of new vegetation.

Answer:

a. extinction

Explanation:

The species that have a very narrow temperature tolerance are usually species that are very specialized for their environment. These species are the ones that suffer the most if there's changes in the environment, and usually are the first ones to go extinct. If the temperature changes, especially if it happens relatively quickly, apart from the difficulty that species will have with the temperature itself, it will also have huge problems with the quickly changing habitat. The end result will be a quick demise and extinction of the species.

3rd: cuticle

4th: guard cells

5th: protection

Explanation:

Answer:

The dermal tissue system safeguards the plants' soft tissues and monitors the associations with the surroundings of the plant. The epidermis refers to a dermal tissue, which is generally a solitary layer of cells enveloping the younger sections of the plants. It discharged a waxy layer known as the cuticle, which prevents loss of water.  

The dermal layer is the outermost layer of the plant. The dermal layer is similar to human skin. The dermal layer possesses a waxy barrier known as the cuticle. The guard cells permit for exchange of gases and monitor loss of water. The prime function of the dermal layer is protection.  

Answer:

A species of lizard is found on the eastern and western sides of part of a mountain range. On both sides, individual populations are small. On the western side, individual populations are relatively close together and males move extensively among populations to breed. On the eastern side, however, populations are farther apart and males seldom move among more than one or two adjacent populations to breed. If you were to study the genetic diversity of western and eastern populations, which pattern would you expect to find?

Each western population would be genetically diverse, although the allele frequencies might differ from one population to the next. Eastern populations would be less diverse, and some populations will have only a limited number of the total alleles available in the species.

Explanation:

They’re genetically different because they only possess half the genes from each parent, so they’re not indentical

Genetic recombination during meiosis makes erotically reproduced offspring genetically different from their parents.

Reproduction may be defined as a biological process through which living organisms give rise to offspring which are fertile in nature.

Due to the fusion of two gametes that are coming from two different parents causes segregation and genes from both the parents are intermingled to develop an offspring. As a result of this, variations may occur in the resultant offspring.

Therefore, genetic recombination during meiosis make erotically reproduced offspring genetically different from their parents.

Answer:

C. Aldosterone increases sodium reabsorption by increasing the number of Na+-K+ ATPase pumps in the luminal membrane of the proximal tubule.

Explanation;

Aldosterone is produced in the adrenal cortex and is stimulated by changes in plasma sodium and potassium levels. It increases sodium reabsorption by increasing the number of sodium channels and Na+-K+ ATPase pumps in the distal tubule and proximal tubule, respectively.

Aldosterone is a steroid hormone produced by the adrenal glands, regulating electrolyte and water balance in the body. It acts on the kidneys, promoting the retention of sodium and excretion of potassium, thereby influencing blood pressure and fluid balance.

Aldosterone is produced in the adrenal cortex and is stimulated by decreased plasma sodium levels and increased plasma potassium levels. It increases the number of passive sodium channels in the luminal membrane of the distal tubule and collecting duct, aiding sodium reabsorption. Additionally, aldosterone increases sodium reabsorption by increasing the number of Na+-K+ ATPase pumps in the luminal membrane of the proximal tubule.

Explanation:

The Industrial Revolution contributed to the first mass scale pollution of the Earth's spheres by the humans. There was pollution prior to it as well, but it was nothing when compared with the period after it occurred. With the development of the industry, lot of waste was released into the waters, or on the soil, often being very toxic and causing severe contamination. The main energy source was the coal, and the coal that was used was releasing enormous amounts of carbon dioxide and sulfur dioxide into the atmosphere. The places that were located near industrial object, or had industrial objects in them faced enormous pollution of the air, which badly affected the health of the humans, animals, and plants. The first acidic rains caused by the human activity started to appear, causing big damage on the forests.

Explanation:

Answer:

No, it is a cycle, so it repeats cyclic.

Explanation:

The cell cycle is divided into two main phases: interphase and mitotic phase.

Interphase is phase characterized by the the cell growth and DNA copy (replication). During this phase, the cell prepares for division, formation of two daughter cells (mitotic phase).

Mitotic phase is subdivided into four phases:

The cell cycle is a regulated process with checkpoints, maintaining accurate progression through phases like interphase, mitosis, and cytokinesis to avoid issues like uncontrolled cell division.

The cell cycle consists of an orderly sequence of events, starting from interphase to cell division, encompassing phases like G₁, S, G₂, and mitosis.

Internal controls called checkpoints monitor each step of the cell cycle to ensure proper progression, with three major checkpoints in G₁, G₂/M transition, and metaphase.

Precise regulation by chemical messengers inside and outside the cell ensures accurate movement from one cell cycle phase to the next, crucial in preventing uncontrollable cell division, such as in cancer.

There two features which facilitates bird to fly are presence of light and smooth feathers and light bones.

Birds are the only living creatures which has the ability to migrate from one place to another through flying. There are many physical features present in their body which facilitates them in flying.

Among the two features and their role in flying are as follows:  

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.

Answer:

What will most likely happen in these lakes is that there will be a decline of several fish populations. The correct answer is A.

Explanation:

The options attached to the question are given below:

A. The decline of several fish populations

B. An increase in the number of fish.

C. An increase in the number of primary producers.

D. Increased predator- prey relationship.

The fishes, just like any other living organisms has ideal body temperature and pH at which they act best. The ideal pH for fish living in lake water is between 6 and 8. If the pH is reduced below this value then the water will become acidic and this will be toxic for the fish population living in the lakes. Therefore, those fish that can not cope will die and there will be a decrease in the fish populations.

Increased acid rain leading to lower pH in lakes can result in damage to aquatic life due to altered physiological processes, depletion of dissolved oxygen, and increased eutrophication. This creates an inhabitable environment for most fauna, excluding some acid-tolerant species.

When the pH of water in lakes decreases to below 5.0 due to an increase in acid rain, several harmful effects are most likely to occur. One of the primary impacts is damage to aquatic life, as most organisms, excluding some acid-tolerant species, can't survive in such acidic conditions. This is because a lower pH can affect metabolic processes and inhibit the survival and reproduction of aquatic organisms. For instance,

fish and shellfish can experience decreased survival rates and altered physiological functions.

Moreover, the increased acidity can lead to the depletion of oxygen in the water body, a scenario that often results in 'dead zones', where the majority of the fauna cannot survive due to insufficient oxygen. Eutrophication, or excessive growth of microorganisms, can also occur, leading to an overall imbalance in the aquatic ecosystem.

The two main factors causing global climate change are human activities, specifically the emission of greenhouse gases, and natural causes including variations in solar intensity and volcanic eruptions. These contribute to global warming and other climatic changes.

The two significant factors causing global climate change are human activities and natural causes. Human activities, such as the burning of fossil fuels, lead to the release of high amounts of greenhouse gases like carbon dioxide and methane into the atmosphere, thus causing global warming and subsequent climate changes. This is known as the greenhouse effect.

On the other hand, natural causes such as variations in solar intensity and volcanic eruptions also contribute to climate change. Variations in solar intensity directly affect the earth's temperature, while volcanic eruptions release gases and solids that can have a cooling effect on the global climate.

Understanding these causes can help address problems like more intense storms, changes in precipitation affecting agriculture, the reduction in rainforest biodiversity, and rising sea levels which are all potential consequences of global climate change.

Answer:

75% would have the dominant traits for coat length, 25% would have recessive trait for coat length.

Explanation:

After completing a punnet square, we could find that our genotypes are 25% LL, 50% Ll, and 25% ll.

If these genotypes were to be physically expressed, LL and Ll would both be expressed as showing the dominant trait.

This means that 75% would have the dominant traits for coat length and 25% would have recessive trait for coat length.

I hope this was helpful! Let me know if you need any clarity.

Final answer:

When determining the offspring phenotypes of two heterozygous dogs (Ll x Ll) for coat length, a Punnett square reveals a 3:1 phenotypic ratio, resulting in three-quarters of the progeny having long fur (dominant) and one-quarter having short fur (recessive).

Explanation:

Understanding Offspring Phenotypes from a Genotype Cross

In genetics, when determining the proportion of offspring phenotypes, specifically with coat color and texture traits, a Punnett square is used commonly. This allows us to visually see the potential genotypes and phenotypes of the progeny when the parents have known genotypes. When two dogs that are heterozygous for a trait mate, each parent has one dominant and one recessive allele for the trait in question. To determine the proportion of phenotypes, you need to establish the alleles for each trait. For example, if we denote 'L' as the dominant allele for long fur and 'l' as the recessive allele for short fur, two heterozygous dogs would have the genotype Ll.

Setting up a Punnett square for Ll x Ll:

The first row and column will have the alleles from each parent (L and l).

By filling out the squares, we predict the potential genotypes of the offspring.

The resulting genotype ratio for Ll x Ll is: 1 LL (homozygous dominant), 2 Ll (heterozygous), and 1 ll (homozygous recessive).

The phenotypic ratio would be:

3 long fur (1 LL and 2 Ll, since L is dominant)

1 short fur (1 ll, as both alleles are recessive)

This gives us a phenotypic ratio of 3:1, where three-quarters of the offspring will have long fur, and one-quarter will have short fur, assuming that long fur is the dominant phenotype associated with the L allele.

Explanation:

- According to National Geographic, 80% of the world’s plants and animals live in forests, and many cannot live elsewhere. With so many of the world’s plants and animals live in forests, that a significant reduction in that habitat, whether tropical rainforest or northern evergreen forest has an impact on biodiversity. Worse, many endangered plants and animals live only in a certain kind of forest habitat. Those species can be lost entirely or can become extinct in the wild very easily.

Climate change

- Cutting down the trees also removes a mechanism to regulate the temperature in forested areas. Hotter days and cooler nights put additional strain on the remaining plants and animals. Growing trees trap a good deal of carbon dioxide. That function cannot be fully replaced by planting single crops, like soy or hemp. The plants are good at holding moisture, trees in particular. Without forest cover, deserts can advance and push out remaining plants and animals.

Loss of soil fertility

-Forested land can be attractive for agriculture because it seems so fertile. In fact, this often isn’t so. The seeming fertility of a rainforest depends on the complex relationships between a variety of plant species. Clearing an area to plant soy or hemp just exposes soil that is high in nutrients at first.  After a few growing seasons, the soil is exhausted and the farmers move on.  The trees and brush in a forest help prevent soil from running off into lakes and rivers and polluting them.

Flooding

- Forests absorb heavy rains that otherwise could run directly into rivers and streams. After a storm, or after several rainy days, a local river can rise to flood stage, even with forests taking up much of the water. Without greatly reduced forest cover comes greatly increased runoff and flooding. Because so much of the world’s population lives along rivers, indiscriminate cutting and burning of forests can be a real threat to lives and property downstream.
