Ecosystems have trouble adjusting to short-term changes. true or false
Hello There!
This is a false statement. Ecosystems don't have trouble adjusting to short-term changes.
Have A Great Day!
Answer: False
Explanation:
Ecosystem can be define as the community of living beings which interact among themselves and with their surrounding environment.
The ecosystem undergoes a series of gradual changes called as succession which helps in overcoming any short or long term change in the ecosystem.
Hence, the statement Ecosystems have trouble adjusting to short-term changes is false.
Hearing the word rabbit may lead people to spell the spoken word hair as h-a-r-e. This best illustrates the outcome of a process known as
Answer:
D. Priming.
Explanation:
Final answer:
The process where hearing the word 'rabbit' influences the spelling of 'hair' as 'hare' is known as semantic priming, a cognitive process where one stimulus affects the response to another.
Explanation:
The scenario described in the question where hearing the word rabbit may lead people to spell the word hair as hare is an example of a cognitive linguistic process. This process is known as semantic priming, where exposure to one stimulus influences a response to a subsequent stimulus, without conscious guidance or intention. In this case, hearing 'rabbit' activates associated words and their spellings, which can influence how someone spells a similar-sounding word, leading them to choose 'hare' instead of 'hair'. Semantic priming is part of our cognitive processes and how we interpret and produce language.

Why are new stars likely to form in irregular galaxies? A. They contain large amounts of gas and dust. B. They're part of the Local Group. C. They don't have regular shapes. D. They contain many black holes.
Please help :)
Answer:
A. They contain large amounts of gas and dust.
Explanation:
Having a lot of gas and dust means that these galaxies have a lot of star formation going on within them. This can make them very bright.
Answer:
The correct answer is option A, that is, they contain large amounts of gas and dust.
Explanation:
A galaxy, which does not exhibit a distinguished regular shape, like an elliptical or a spiral galaxy is considered as an irregular galaxy. The irregular galaxies may comprise enormous concentrations of dust and gas.
The stars have the possibility to get formed in the irregular galaxies as they seem to exhibit huge concentrations of gas and dust, which is an essential criterion for the formation of new stars to take place.

Malthus studied limited resources and the impact of limited resources on human populations. How did these ideas contribute to Darwin's ideas?
A. Limited resources in an environment forces more genetic changes in individuals, allowing the species to evolve more quickly.
B. Limited resources in an environment means that the individuals of a species cooperate so that all individuals survive.
C. Limited resources in an environment forces some individuals to survive without food.
D. Limited resources in an environment means that not all individuals of a species will survive or reproduce at equal rates.
Answer:
Option (C).
Explanation:
Malthus had stated that the population growth was exponential. He explained the relationship between population growth and resources.
Malthus study on population growth and limited resources on human population has contributed to the Darwin's idea of evolution. Limited resources in a population allows the survival of some individual species only. Natural selection favors the selected population and species adapt in the environment and transfer beneficial allele to its next generation.

The Milky Way is held together by a black hole's gravitational force. Since the stars near this black hole move at a high speed, what can you infer about the black hole? A. Its location B. Its depth C. Its speed D. Its size
Answer:
A. Location
Explanation:
A black hole is a massive structure in the space from which light cannot escape. Therefore, the depth of the black hole (B), the speed (C), and size (D) are extremely difficult to measure. However, scientists have been able to locate the position of black holes via the movement of stars and gases around it. Typically, since black holes are extremely dense objects, masses spins around the black holes and form a structure called an accretion disk. By looking at the speed of stars, the scientists can detect where the black holes are in the space.
Answer:
A. Its location

Monkeys and humans share many of the same DNA sequences and have similar proteins, indicating that a) the two groups belong to the same specie b) the two groups share a relatively recent common ancestor c) the two groups first appeared on Earth at about the same time d) monkeys evolved from humans
Answer:
B
Explanation:
If two creatures share the same DNA traits, this means that they have a common ancestor, whether it be recent, or distant.
We know for a fact, that Monkeys did not evolve from humans, due to the fact they came first. Humans highly likely evolved from monkeys, so we may be considered the same, but genetically we are not.
That rules out all other answers besides B.
Hope this helped! :)
The significant overlap in DNA and proteins between monkeys and humans points to a relatively recent common ancestor, but it does not mean they are the same species, evolved from each other, or appeared on Earth at the same time.
Explanation:The similarities in DNA sequences and proteins shared between monkeys and humans suggest that these two groups share a relatively recent common ancestor. This doesn't mean they belong to the same species or that monkeys evolved from humans. It also doesn't imply they first appeared on Earth at the same time. It means that they have a common ancestor from which both species have evolved, separately, into the distinct creatures they are today. This ancestor lived far more recently than the ancestors we share with less closely related Biological groups.

If you put the 2 rats in different environments, you will not only observe the adaptations they use to survive in different environments, but what consequences will occur if they are in a unfamiliar environment
Answer: C. Put the two groups in different environment.
Explanation:
Speciation is the process in which new species develop from the parent or pre-existing species in due course of evolution. The following are the types of speciation.
1. Allopatric speciation: This results when the two populations of the same species, are separated geographically.
2. Sympatric speciation: This results when the two populations living in the same area diverge due to changes in the behavior, morphology and in genomic level. This results in reproductive isolation among members of the same species belonging to two distinct populations.
Among the options given, C. Put the two groups in different environment. is the correct option. This is because of the fact that this will favor allopatric speciation. As due to geographical barrier, the separated groups will develop traits different from the parent species. Hence, result in development of new species.
Which muscle cell structure stores calcium ions that are used to trigger the contraction?
The Sarcoplasmic Reticulum, a specialized endoplasmic reticulum in muscle cells, stores calcium ions that are necessary for muscle contractions.
Explanation:In the context of muscle cell structure, the specific structure that stores calcium ions which are needed to trigger the muscle contraction is called the Sarcoplasmic Reticulum. It's a specialized endoplasmic reticulum found in muscle cells that holds a high concentration of calcium ions.
When the muscle is signaled to contract, calcium ions are released from the Sarcoplasmic Reticulum, allowing the muscle proteins to interact and create movement.

A large population of houseflies was sprayed with a newly developed, fast-acting insecticide. the appearance of some houseflies that are resistant to this insecticide supports the concept that
Final answer:
The presence of insecticide-resistant houseflies illustrates the concept of pesticide resistance and microevolution, where selective pressure from the use of pesticides leads to the survival and reproduction of resistant individuals, causing resistance to increase within the population over time.
Explanation:
The appearance of some houseflies that are resistant to a newly developed insecticide supports the concept of pesticide resistance and is an example of microevolution. This happens when a population of insects is subjected to a selective pressure, such as a chemical pesticide, and the few individuals that by chance carry genes that confer resistance to the insecticide are more likely to survive and reproduce.
Over time, these resistant genes are passed on to the offspring, and the resistance trait becomes more common in the population. Eventually, this could lead to the pesticide becoming ineffective, requiring higher doses or the development of a new pesticide. This cycle of development of insect resistance is a significant challenge in managing pest populations and has been observed since the usage of DDT in the 1940s.

Succulent plants such as aloes are known for their thick stems and leaves, which allow them to store water. Which statement best explains how succulents' thick stems and leaves evolved through natural selection?
A. Thick stems and leaves were selected because succulents need to consume a large supply of water every day.
B. Thick stems and leaves were selected because they help succulents take up more space, which in turn helps them capture more sunlight.
C. Thick stems and leaves were selected because they guarantee that young succulents already have all the water they will need for the rest of their lives.
D. Thick stems and leaves were selected because succulents with these characteristics are more likely to survive hot, dry weather and, thus, produce more offspring.
Answer:
D. Thick stems and leaves were selected because succulents with these characteristics are more likely to survive hot, dry weather and, thus, produce more offspring
Explanation:
The succulents have not always been as they are now, but they have evolved from plants that looked different and existed in different weather conditions. As the environment has been changing, in order to survive, the succulents started to develop traits that would be advantageous for them to survive in the hot and dry weather. The succulents that started to develop such traits, like the thick stem and leaves were the ones selected to survive, as they were the ones that had the advantage in this type of environment. The thick stems and leaves enabled them to store as much water as possible when there is, and also to preserve it for long periods of time, while the succulents that didn't possessed this traits died out because they were not able to sustain the new conditions, nor to be able to reproduce effectively.
We live in the Cenozoic era, and scientists know more about this era and the epochs it's divided into than any other time period. Why is this?
Scientists have a better understanding of the Cenozoic Era, the era we live in, because it is the most recent and its geological record is well-preserved, containing clear evidence of past life forms, including mammals' rise to dominance after dinosaurs' extinction.
We live in the Phanerozoic eon, within the Cenozoic era, which is known as the Age of Mammals. This era is divided into different periods and epochs, including the Quarternary period and the Holocene epoch. The Cenozoic era began about 65 million years ago and continues to present day. It's characterized by the emergence and dominance of mammals, including human ancestors, after the extinction of dinosaurs.
Scientists know more about the Cenozoic era than any other time period because it is the most recent and therefore the best preserved in the geological record. During the Cenozoic, most of the organisms that we share Earth with evolved. Additionally, the closer proximity in time allows for better preservation and study of fossils, giving us clearer evidence of past life forms and environments.
Throughout the Cenozoic, Earth experienced significant climatic and geographical changes, such as the ice ages and tectonic shifts. These shifts contributed to the evolution and distribution of species. The ongoing nature of these changes, as well as human interest in understanding our own origins, drives the in-depth study of this era.

1. In what type of ecosystem can this population be found?
2. How might this population suddenly increase? How might this affect the ecosystem
3. What might happen to the ecosystem if this population were removed?
Answer:
1) The ecosystem would have the abiotic factors of low precipitation, dry winds, and low temperatures. The biotic factors would include the animals living with the penguins such as polar bears and yaks.
2) The population would suddenly increase if either the penguin's predators had a drop in numbers or if the penguin's food source became more readily available. This growth in population would result in food becoming harder to find and predators once again growing in numbers. This would eventually cause the penguin population to shrink once more.
3) Predators would die out. Whatever organism(s) were the penguin's food source would grow in size exponentially. Other animals may suffer a drop in numbers if the penguin's predators choose to prey on them.
Which of the following statements is considered true of Neanderthals? A. They had some system of religious beliefs about afterlife. B. They had smaller brains than homo sapiens (modern humans). C. They evolved into homo sapiens. D. They emerged after the ice age.
Answer:
A. They had some system of religious beliefs about afterlife
Explanation:
The Neanderthals are one of the closest cousins to the modern humans, in fact, lot of people in Europe and Asia have small percentage of Neanderthal gene in them. Unlike the popular belief, the Neanderthals were not stupid, bulky, primitives, but instead they were much more evolved, had very large brain capacity, created art, and it is believed that they even had some system of religious beliefs about afterlife. The clue for the supposed system of religious beliefs about afterlife comes from a burial site, where a Neanderthal was buried with an ax, thus a weapon. When comparing such action with the human behavior, it resembles a lot to the ancient human beliefs about afterlife, where weapons and other objects were commonly left in the graves.

Plate divergence is best described a/an _______ process.
O A. orogenic
O B. isostatic
O C. taphrogenic
O D. epeirogenic
Answer:
C. taphrogenic
Explanation:
The plate divergence can be described as a taphrogenic process. The taphrogenic processes are the processes through which gaps occur in the crust, and the crust is moving away from the gap that has opened up. This is exactly how the divergent boundaries form. The strong convection currents of the mantle manage to crack the crust, and the magma manages to penetrate through it and melt it. As the magma reaches the the surface, it starts to come out, propelling itself upward, and as it cools of it creates new crust. The magma continues to come out, and more and more new crust is pilling up, pushing the old crust away from the divergent plate boundary.

What is a phospholipid composed of?
a. a nonpolar head and a polar tail
b. a nonpolar head and tail
c. a polar head and a nonpolar tail
d. a polar head and tail
A phospholipid is composed of a polar head and a nonpolar tail. These components allow it to form a bilayer in cell membranes.
The correct option is c.
Explanation:A phospholipid is composed of a polar head and a nonpolar tail. The polar head is hydrophilic (water-loving), which means it is attracted to water.
The nonpolar tail, on the other hand, is hydrophobic (water-fearing), and not attracted to water.
This configuration makes phospholipids the perfect building block for cell membranes, and results in the formation of a phospholipid bilayer when in aqueous solutions, allowing them to separate the inside of a cell from its outside environment.

Plants which produce their gametes in flowers are called: I know it's not gymnosperms. So which one is it?
angiosperms
vascular
antheridium
gymnosperms
Answer:
Plants which produce their gametes in flowers are called angiosperms.( first choice)
Plants that produce gametes in flowers are known as angiosperms, which include a wide range of plants such as herbs, shrubs, and most trees, and are characterized by having seeds within the ovaries of flowers.
Explanation:Plants which produce their gametes in flowers are called angiosperms. Unlike gymnosperms, which produce seeds in cones, angiosperms produce seeds within the ovaries of flowers. After fertilization, the walls of the ovary thicken and often develop into fruit, aiding in seed dispersal.
Angiosperms include a vast array of plants including grasses, herbs, shrubs, and most deciduous trees. The main parts of a flower are the sepals and petals, which protect the reproductive organs, such as the stamens that produce the male gametes (pollen grains) and the carpels that contain the female gametes (eggs within the ovules).
