Answer:

review all proposals for animal research to be sure the procedures to be used are appropriate and humane.

Explanation:

The Institutional Animal Care and Use Committee (IACUC) is a federal committee responsible for approving and/or prohibiting the use of animal (nonhuman vertebrate) subjects for research, testing and teaching purposes, as well as the inspection of animal facilities. IACUC evaluates the institution's animal programs and procedures as described by the Office of Laboratory Animal Welfare (OLAW). This committee has the task to verify animal's well-being by minimizing pain and distress (for example, by ensuring the use of non-invasive methods when possible). Researchers/educators that use animals for research/teaching purposes must previously submit a written request defined by the IACUC's guidelines.

Answer:

b. Gravitational Potential Energy

Explanation:

The olive oil currently holds potential energy, which it is given from the pull of gravity, constantly pulling it down to the earth.

If the olive oil were knocked down the gravitational energy would then be kinetic, or moving. The other choice simply don’t make sense, as the olive oil is unlikely to be electrically charged, nuclear reactive, or -as it’s not currently moving- have kinetic energy. Therefore the proper response is:

Answer:

Light waves can travel with and without mediums.

Explanation:

Light waves are a type of electromagnetic wave. Some of the characteristics (properties) of light waves include;

I. The wavelengths of light range from 400 nm to 700 nm.

II. Light waves are transverse waves.

III. The speed of light is 3 x 10^8 m/s.

Therefore, from the aforementioned characteristics it can be inferred that light waves can travel with and without mediums.

This ultimately implies that, light wave is an electromagnetic wave that do not require a medium of propagation for it to travel through a vacuum of space where no particles exist.

Answer:

The correct answer is - reuptake.

Explanation:

The process that reabsorbs the neurotransmitters known as reuptake which reduced the number of neurotransmitter molecules. Neurotransmitter transporter found on the outer membrane of the plasma membrane assists the process of reuptake by reabsorbing the neurotransmitter molecules from the specific synaptic gap. Neurotransmitters recycle by this process in order to reuse again after a time for the particular signal to last.

Thus, the correct answer is - reuptake.

Answer:

Adult anteaters compete for food and many young anteaters die

Explanation:

As there are not many predators and the number of ants is abundant, the population of anteaters should grow on a large scale, however, this is not what happens, since the size of the population is the same for twenty years. This shows that the anteater population itself is regulating the size of the population through internal disputes, where anteaters, due to the high birth rate, end up competing for food and shelter, causing the most young and inexperienced individuals to be killed.

Answer:

The correct answer is ''forms a channel in the target cell membrane that causes cytolysis.''

Explanation:

The membrane attack complex (MAC) has the essential effect of producing a notable osmotic imbalance in the microorganism that leads to its cytolysis (in Gram-negative bacteria it inserts into the outer membrane, favoring the entry of lysozyme, and in Gram-positive ones insert into the cytoplasmic membrane, destroying the electrochemical gradients). The lytic pathway corresponds to the final reactions of the complement system. It begins when the C5 convertase enzymes formed either in the classical pathway, MBL or the alternative, fix the factor C5 and fragment it into C5a (anaphylatoxin) that passes into the fluid medium and C5b, which binds non-covalently to C3b. The C5b fraction captures C6 and C7 from the fluid phase, forming a stable C5b67 complex with chemotaxic activity and membrane-binding capacity, which when joining the C8 fraction is cytolytic, and acquires the ability to interact with C9 molecules, forming the complex C5b6789. The C9 molecules then undergo conformational changes, enhance and accelerate the penetration of this membrane attack complex (MAC), giving rise to the formation of channels that allow the free exchange of sodium and water with the outside of the cell, causing the consequent  osmotic lysis (cytolysis)of the attacked cell, since C9 is structurally homologous to perforin, a protein released by cytotoxic T lymphocytes and NK cells, and which is also responsible for the formation of pores in the membrane of the target cells.

Answer:

because the cell is the smaller unit that has the properties of life

Explanation:

There are three basic principles/statements that are the basis of the unified cell theory, which was proposed by Matthias Schleiden and Theodor Schwann in 1838. All living organisms are composed of cells (first principle), whereby cells can be considered as the basic, structural and organizational units of all organisms (second principle). Moreover, new cells always arise from existing cells (third principle). In consequence, the cell is the smaller unit that has the properties of life in order to carry out all metabolic processes including reproduction, growth, development, etc.

The fossil record

This supports Darwin's theory of evolution, which states that simple life forms gradually evolved into more complex ones. Evidence for early forms of life comes from fossils. By studying fossils, scientists can learn how much (or how little) organisms have changed as life developed on Earth.There are gaps in the fossil record because many early forms of life were soft-bodied, which means that they have left few traces behind. What traces there were may have been destroyed by geological activity. This is why scientists cannot be certain about how life began.

Fossils provide a snap shot of the past and allow us to study how much or how little organisms have changed as life developed on Earth.

Explanation:

The Panama isthmus is indeed a patch of land which separates its sea from its Atlantic ocean to The pacific in two halves. The Panama Isthmus allows spreading the seafood applicable state, although due to geographical barrier, the very same turtle species were isolated. Its deep squirrels of liquid are diverged quite early as being against shallow water shrimps which are characterized by the rising of the Jamaica isthmus, first off the island can be crossed until it was closed through shallow water prawns and shallow-water animals. If Panama's black sea was established less than 1000 years, it has a greater effect on deepwater shrimp and very low water lobsters. Consequently, in water depth prawns, a disparity in hereditary degree (DNA) is higher than in shallow species. The deep waters have been affected earlier so the variation in DNA sequences throughout all sister species will not be the same.

Recessive

Explanation:

When there is a skipped generation, the trait must be RECESSIVE. For dominant trait, having 1 dominant allele will give you affected phenotype. It can never give a skipped generation.

Answer:

Explanation:

Answer:

a. the second nucleotide is wrong. It is a U but should be an A. No other nucleotides were effected by this, only the one was effected. This is a Point (Substitution) Mutation.

b. the third nucleotide is wrong. It is a T that was inserted. As you can see, the rest of the nucleotides are right, but since the T was added, it will mess up how the rest of the sequence is read. It will be read UAT GGC GAA... instead of UAG GCG AAU... see how it messed it up? This is an Insertion (Addition) Mutation.

c. the second nucleotide was deleted. This is called a Deletion Mutation. It will mess up the rest of the sequence, similar to how the example above did.

I hope that helped you understand!
