Answer:
Option A is correct
Explanation:
Given
Pika are eaten by many animals of the grass land. The burrows of Pika are helpful in draining the ground water rapidly and the burrows also acts as nesting site for many bird species. Pikas consume grass and hence they are competitors of livestock animals.
Removing Pikas from this ecosystem will destabilise the ecosystem as all the grass land predators will not get sufficient food. If Pika will not be there, then their burrows too will not exist and hence the excess ground water cannot be absorbed. Also the bird species will not be able to use burrows as nesting site.
Hence, option A is correct

How can marine mammals survive underwater for so long?
Answer:
Special properties of an oxygen-binding protein in the muscles of marine mammals, such as seals, whales and dolphins, are the reason these animals can hold their breath underwater for long periods of time, according to a new study. ... In fact, the amount was so high in the muscle that it almost looked black in color.

Explanation:
Carbon dioxide is carried in blood plasma.
Human blood also contains red blood cells and white blood cells.
Explain how the structure of red blood cells and white blood cells is related to their function.
(6 marks)
Answer:
Plasma is the main component of blood and consists mostly of water, with proteins, ions, nutrients, and wastes mixed in. Red blood cells are responsible for carrying oxygen and carbon dioxide. Platelets are responsible for blood clotting. White blood cells are part of the immune system and function in immune response.
Blood is important for regulation of the body’s pH, temperature, osmotic pressure, the circulation of nutrients and removal of waste, the distribution of hormones from endocrine glands, and the elimination of excess heat; it also contains components for blood clotting. Blood is made of of several components, including red blood cells, white blood cells, platelets, and the plasma, which contains coagulation factors and serum.

Reproductive isolation occurs when
A- some catastrophic event greatly reduces the size of the population
B- The gene pool of different populations have become very diversified
C-members of different populations can no longer meet successfully
D-small numbers of individual moves and starts in new population
Answer:
The correct answer is - C. members of different populations can no longer meet successfully.
Explanation:
Reproductive isolation is the process that occurs when two or more species or populations are not able to interbreed. The mechanisms or properties that are used to preventing individuals of separate species from mating called Reproductive isolation mechanisms.
The different barriers can cause this reproductive isolation such as different mating seasons. These barriers could be behavioral or temporal or ecological isolations.

Do mutations always lead to evolution?
Yes, because mutations create adaptations that give a competitive advantage.
No, because most mutations lead to death of the organism.
No, because some mutations happen in the body cells, so they are not passed on.
Yes, because there would be no change in populations without mutations.

HOW DO THE OCEANS CURRENTS AFFECT CLIMATE
Answer:
Explanation:
Ocean currents act much like a conveyor belt, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics. Thus, ocean currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth's surface.

Two humans mate who are heterozygous for earlobe shape where attached earlobes (A) are dominant to free earlobes (a), and earwax quality where dry earwax (e) is recessive to wet earwax (E ). What is the probability that their first child will have dry earwax and attached earlobes
Answer:
3/16
Explanation:
This question involves two different genes coding for earlobe shape and earwax quality. The alleles for attached earlobes (A) and wet earwax (E) are dominant over the alleles for free earlobes (a) and dry earwax (e).
According to this question, two humans mate who are heterozygous for both genes i.e. AaEe × AeEe. Each parent will produce the following gametes: AE, Ae, aE, ae.
Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:
* Attached earlobe, wet earwax (A_E_) = 9/16
* Attached earlobe, dry earwax (A_ee) = 3/16
* Free earlobe, wet earwax (aaE_) = 3/16
* Free earlobe, dry earwax (aaee) = 1/16
Hence, the probability of these parents having their first child with dry earwax (ee) and attached earlobes (A_) i.e. genotype A_ee is 3/16.
Why is tRNA called Transfer RNA?
A. Because it is responsible for transferring the protein out of the cell.
B. Because it is responsible for transferring the protein-building instructions to the ribosome.
C. Because it is responsible for transferring the right amino acid to the ribosome to create the protein.
Answer:
C
Explanation:
When a tRNA recognizes and binds to its corresponding codon in the ribosome, the tRNA transfers the appropriate amino acid to the end of the growing amino acid chain.
Answer:
C. Because it is responsible for transferring the right amino acid to the ribosome to create the protein.
Explanation:
The tRNA is known as the Transfer RNA because it is responsible for transferring the right amino acid to the ribosome to create the protein.

If you are observing worms, ants, and caterpillars, you are studying a biological _________________.
A. community
B. species
C. individual
D. population
E. none of the above
If you are observing worms, ants, and caterpillars, you are studying a biological species. Thus, the correct option is B.
What is Biological species?Biological species may be defined as a cluster of organisms that can reproduce with one another in nature and produce fertile offspring.
A Community may be defined as a group of individuals belonging to different species living in the same area. A Population may be defined as the number of the same species living in the same area at a particular time.
Here, worms, ants, and caterpillars are organisms of different species with different characteristics such as mode of nutrition, reproduction, and response to the environment.
The biological species are considered as an integral part or component of an ecosystem. The greater the biodiversity in an ecosystem, the greater the stability of the species within that ecosystem.
Therefore, if you are observing worms, ants, and caterpillars, you are studying a biological species. Thus, the correct option is B.
