Answer:
Formation. When the solar system settled into its current layout about 4.5 billion years ago, Earth formed when gravity pulled swirling gas and dust in to become the third planet from the Sun. Like its fellow terrestrial planets, Earth has a central core, a rocky mantle and a solid crust.

Use the text to identify the sentences with evidence that matches the claim.
Claim 1 --> Tropical rainforests contain more biodiversity than all other biomes.
1) Biodiversity refers to the total number of different species of all kinds living in an area.
2) Tropical rainforests have many of the climate characteristics that organisms of different species need to grow, such as warm temperatures, plenty of rain, and many food sources.
3) There are large amounts of daily sunlight, which provides a great deal of energy to a variety of rainforest organisms.
4) Surprisingly, rain forest soil is very poor.
5) Due to the large amounts of rainfall, nutrients are leached out of the soil quickly.
6) Warm temperatures cause dead organisms to decay quickly, and the nutrients are then used by many different plants.

Isabel's first car had a manual stick shift. After many years of driving an automatic car, she needs to use her sister's car, which also has a stick
shift. Isabel takes a few minutes to get used to shifting gears. Which memory system Is she using to recall this information?
• A. episodic memory
O B. procedural memory
• C.
semantic memory
)D.
sensory memory
Answer:
Procedural memory
Explanation:
Isabel has to recall the information about using a manual stick shift. For this reason, she is using long-term, explicit, declarative and episodic memory system.
Human memory system can be broadly classified as: sensory memory, short-term memory and long-term memory.
Long-term memory is used to recall information. If the information are about facts, events and experiences then explicit, declarative and episodic memory helps to recall all information. This will help Isabel to recall all information about driving a car with a manual stick shift and she will be able to drive her sister's car.

Which of the following statements about active transport is true?
Molecules move down the concentration gradient.
ATP is not required to move molecules through the membrane.
ATP is formed as molecules pass through protein channels.
It results in a higher concentration of molecules on one side of the membrane.
Answer:
It results in a higher concentration of molecules on one side of the membrane.
Explanation:
Active transport is the transport of molecules up the concentration gradient. This means that molecules are going from low density to high density. This is the opposite of natural diffusion. So, it requires ATP to move the molecules this way. Diffusion normally occurs to maintain homeostasis and an equal amount of concentration on both sides of a membrane. But, with active transport, since molecules are moving up the gradient, the opposite happens and the concentrations are unequal.
Why do oxygen levels drop sharply during eutrophication?
Explanation:
during eutrophication, there is a presence of excess algae in the water body. this causes an excess overconsumption of available organic materials by algae, causing the oxygen levels to reduce rapidly.
When the algae population grows rapidly, it may hinder sunlight from reaching other lifeforms and cause dissolved oxygen levels to fall.
What is eutrophication?Eutrophication is the substantial increase in phosphorus, nitrogen, and other organic material in an ageing aquatic environment such as a lake.
As the amount of organic material that can be subdivided into nutrients increases, so does the efficiency or fertility of such an ecosystem.
When the algae population grows rapidly, it may prevent sunshine from reaching other organisms and cause dissolved oxygen levels to fall.
The primary environmental impacts of eutrophication are an increase in suspended particles caused by extensive macroalgal blooms, a decrease in water clarity, and an increase in precipitation rate, which has resulted in the destruction of benthic habitat due to shading of submerged vegetation.
Thus, this way, oxygen levels drop sharply during eutrophication.

ASAP Determine whether the statement is true or false and why. “We have discovered a series of humanoid fossils that are similar to humans, but not human. Each of these humanoid species dates to a different period in time becoming more human-like the closer to the present they are, showing a clear evolution into humans.”
A. False, it should read “We have discovered no series of humanoid fossils that are similar to humans, showing a clear lack of any transitional fossils as evidence of human evolution”
B. True
C. False, it should read “We have discovered a series of humanoid fossils that are similar to humans, but not human. Each of these humanoid species dates to a different period in time becoming less human-like the closer to the present they are, showing a clear evolution away from humans.”
D. False, it should read “We have discovered a series of humanoid fossils that are similar to humans, but not human. Each of these humanoid species dates to the same period in time, showing that many human-like species existed at once, but all went extinct.”
The statement is true.
Human evolution is a scientific term that refers to the process of biological evolution of the human species from its ancestors to the present.
The current knowledge of human evolution is the result of the convergence of various sciences such as:
Genetics.Physical anthropology.Paleontology.Geochronology.Archeology.Linguistics.The results of various studies relate the current human species as a result of multiple evolutionary processes of hominimus species, ardipithecus, australopithecus, and homo that through time improved different aspects until reaching the human species that exists today.
According to the above, what is described in the fragment presented is true because it presents a correct version of what happened in human evolution. Meanwhile, options A, C and D are incorrect because they do not present correct information regarding human evolution.

When many nucleotides link together, they form a biomolecule responsible for storing genetic information called nucleic acids. Thus, the correct option is B.
What are Nucleotides?Nucleotides may be defined as the basic unit of the polynucleotide chain of nucleic acids such as DNA or RNA. Each nucleotide is composed of three components. They are as follows:
A nitrogenous base.A pentose sugar (ribose in the case of RNA, and deoxyribose in the case of DNA).A phosphate group.Nucleotides are the monomers of nucleic acids. Each nucleotide is joined together by covalent bonds known as phosphodiester linkage. This linkage is present between the phosphate group of one nucleotide and the third carbon atom of the pentose sugar of next nucleotide.
Therefore, nucleic acids are formed when many nucleotides link together which are responsible for storing the genetic information.

Complete question:
Frequently, a group of related species will each have a unique courtship ritual that must be performed correctly for both partners to be willing to mate. Such a ritual constitutes a ________ ________ reproductive barrier.
Group of answer choices
A) behavioral . . . prezygotic
B) mechanical . . . postzygotic
C) temporal . . . prezygotic
D) gametic . . . postzygotic
Answer:
A) behavioral . . . prezygotic
Explanation:
The biological concept of species states that individuals of a species can not mate and reproduce with individuals of another species. But if they get to reproduce, the progeny will not be viable or fertile. There will not be any reproductive success.
There are different reproductive isolation mechanisms, which are barriers that inhibit or interrupt the genetic flow between different species.
Reproductive barriers are isolation mechanisms that prevent mating between two or more species. The prezygotic mechanism avoids fertilization between individuals of different species, while the postzygotic mechanism impedes the zygote to develop and reach the adult stage.
There are different types of reproductive barriers.
Pre-copulatory o pre-ziygotic:
Ecological or by habitat isolation; Seasonal or temporal; Sexual o ethologic; Mechanic; Gametes incompatibility.Postzygotic mechanisms or barriers include
Hybrid inviability, Hybrid sterility, Hybrid reduced viability or fertility, Cytoplasmic interactions.Behavioral isolation is also known as ethological isolation or sexual isolation. This is a prezygotic barrier that refers to the fact that even when many species occupy the same area, they are not sexually attracted to each other, and might be rejected because of behavioral factors, not getting to mate. This mechanism includes courtship patterns or mating rituals and specific chemical signals that allow recognition between individuals of the same species.
