Answer: DNA is a nucleic acid

Explanation:

The acronym DNA stands for deoxyribonucleic acid.

Answer:

a. Developing cells may express different parts of their identical genetic instructions.

Explanation:

Humans are multicellular organisms i.e. we possess many cells in our body. These cells increase as a result of division. Although all of the cells of humans develop from one fertilized egg (zygote), the human is born with many different types of cells because of a process called CELL DIFFERENTIATION.

Cell differentiation is a process in multicellular organisms where a cell becomes more specialized in function as it divides. The set of genes contained in each cell are not expressed simultaneously i.e. some genes are expressed while others are repressed. This is how cells with the same gene possess different functions. Therefore, according to this question, developing cells may express different parts of their identical genetic instructions to be of different types.

Answer:

a. 1/2 b. The organism is an animal

Explanation:

a. What is the medullary index for an organism that has a medulla width of 2cm and hair shaft width 4cm?

Medullary index = diameter of medulla/diameter of hair.

Given that diameter of medulla = medulla width = 2cm and diameter of hair = hair shaft width = 4cm,

Medullary index = diameter of medulla/diameter of hair = 2 cm/4cm = 1/2

b. Is this organism human or animal?

Since the medullary index = 1/2 > 1/3 (if it is ≤ 1/3 it is human hair and ≥ 1/2 it is animal hair), it is animal hair. So, the organism is an animal.

Answer:

The circulatory system, also known as the cardiovascular system, is a simple loop which starts, and ends, with your heart. It is a closed system, meaning blood does not enter or leave the system during its journey from your heart to your body and back again.

Answer and Explanation:

Cells directed their growth by getting the signals from distant or local bases and respond by directing signals. Each signal changes the cell state and decides how cells reply to consequent signals. RTK (receptor tyrosine kinase) signaling is needed for the arrangement of the R1-R7 photoreceptors. It activates the phyllopod transcription through the Ras/MAPK pathway. The Phyllopod transcription codes an adapter protein that guides the ubiquitin ligase Sina to target the transcription factor named Ttk (tram track) for deprivation.  Tram track (Ttk) is the main inhibitor of the development of photoreceptors. The cells that do not damage Ttk become the ommatidium components, while those cells that damage it continues to develop photoreceptors. Receptor tyrosine kinase signaling is also involved in the development of ommatidium. Receptor tyrosine kinase signaling controls the propagation and existence of cells before they are employed in the cluster. RTK also regulates the differentiation of cone cells. Whether a cell becomes a photoreceptor or not is also decided by RTK signaling events.

Pinocytosis and phagocytosis are examples of active transport that cells use to maintain homeostasis, hence option A and C are correct.

The propensity to oppose change in order to preserve a stable, largely constant internal environment is known as homeostasis. Negative feedback loops are frequently used in homeostasis to combat deviations from set positions in a variety of properties.

Moving uphill is considered active transportation. A cell must expend energy to transport materials against a concentration or electrochemical gradient.

This is precisely what active transport systems do they use energy, frequently in the form of ATP, to keep the proper concentrations of ions and molecules in living cells.

Therefore, option A and C are correct.

Explanation:

Solar power is energy turned by the sun into thermal or electricity. The cleanest and most generous source of usable green energy is solar energy.

Solar energy, Solar radiation capable of heat creation, chemical reactions or power generation. The cumulative number of solar energy events on earth significantly exceeds existing and planned energy needs worldwide.

Answer:

Biogeochemical cycles are the various cycles that essential for the living organism. In these cycles, elements or compounds are moved between living and nonliving organisms. These cycles are interconnected to support life and move the energy and molecules into the loop. Examples of such biogeochemical cycles are the water cycle, carbon cycle oxygen cycle, and many others.

Carbon is an element that is important and moves in different spheres of earth including the atmosphere, geosphere, and biosphere. Similarly, water is a compound essential for living organisms and moves from the hydrosphere to living organisms and the atmosphere.

Answer:

They will evolve into a new species

Explanation:

The most likely result from this scenario is that the now isolated group of beetles will evolve and become a new beetle species that is unique from the old population.

The beetles have become geographically isolated from the original population and this makes them become a new species through the process of allopatric speciation. Allopatric speciation is an evolutionary mechanism of species formation as a result of being geographically separated from the old population. It is as opposed to sympatric speciation in which a new species is formed within a population of species without being geographically barred from the original population.

The fact that the isolated species are now in an environment that is different from that of the original population means that they will take a different route to evolve in terms of trying to adapt to the changes that would be occurring in their environment.

Answer:fertilization

Explanation:

Answer: Sexual reproduction occurs in three stages: pollination, fertilization, and dispersal. During pollination, pollen is transferred from the anther to the stigma. Once the pollen is stuck to the stigma, it produces a pollen tube that grows down the style to the ovary and into the ovule. A sperm cell then travels down the pollen tube into the ovule and fertilizes the egg cell. The fertilized egg is called a zygote. This zygote grows into a plant embryo. The embryo is located inside the seed along with the seed coat and stored food. The ovule develops into the seed. The ovary develops into the fruit that protects the seed. The fruit also helps disperse the seed. Seeds are dispersed, or spread, to new locations, where they grow into seedlings.  or pollen is taken to the stigma. i took the test

The depolarization of the ___SOMA NEURONAL_________ normally generates the action potential that leads to the depolarization of all other cells of the heart muscle.

Explanation:

The depolarization of the neuronal body, that is, the body of the neuron, generates an action potential that is transported throughout the axon, until in the motor unit (union between neuron and muscle) the action potential is transmitted to the cardiac cell, depolarizing the membrane of the myocardial cell and thus effecting cardiac contraction.

Cardiac contraction occurs in a controlled, rhythmic and systematic manner, with autonomic character and as a consequence of the release of calcium from REL to LIC

Answer:

Green

Explanation:

Answer:

D. Different parts of the molecule have slightly different charges

Explanation:

Water is a polar molecule because different areas of the molecule have different and opposite charges

Oxygen has a higher electronegativity than hydrogen, which means the electrons of the water molecule will stay closer to the oxygen than the hydrogen.

This creates an uneven distribution where the oxygen has a partial negative charge and the hydrogen has a partial positive charge.

So, D is the correct answer.

Explanation:

Clean energy are renewable energy. This are energy from natural sources that are renewed without extra cost. Sun, wind, water are examples of renewable natural resources that helps generate clean energy.

The energy are refer to as clean because, they do not lead to any deposit of gasses that can affect the environment leading to environmental pollution. They have little or no side effects, no combustions or release of gases that are toxic or can deplete the environment as in the case of non- renewable energy.
