The Law of Independent Assortment states that alternate versions of genes cause variation in inherited characteristics. The correct option is D.

The law of Independent Assortment is given by Gregor Mendel. He was a scientist and botanist who gave very useful discoveries in the field of hereditary.

The law of Independent Assortment states that the gene from both parents for the same traits does not overlap, They were present independently, and they are the reason for the variation.

Variation is the different characters present in an organism. The recessive gene and the dominant gene are the two types of alleles. The dominant allele is shown in the organism.

Thus, the correct option is D. alternate versions of genes cause variation in inherited characteristics.

Receptors provide information to nervous system about missing cells.

Explanation:

Your body know when cells are missing due to nervous system. The network of nervous system spreads throughout human body which provide information about what is going on in the body. If the cells are missing due to injury, the nervous system gives instruction to the body to produce more cells and transported that cells to the region where these cell are required. So receptors are responsible to provide information to nervous system about missing cells.

The body knows cells are missing as a result of the receptors sending

to the central nervous system.

The human body consists of cells which have neurons. These neurons are

responsible for the passage of messages and information to other parts of

the body.

When a cell is missing from the body, signals are passed to the central

nervous system which consists of the brain and spinal cord and they then

relay impulses which helps to fix the issue so as to ensure optimal

functioning of the body.

osteogenesis imperfecta is an inherited genetic disease that mainly affects the bones.  

Explanation:

Osteogenesis imperfecta is an inherited genetic disease associated with alterations in collagen synthesis, which have been shown to increase the risk to suffer bone fractures. This genetic disorder is characterized by different health problems including, among others, fragile bones, reduced skeletal mass, skin hyperlaxity, malformations in the central nervous system, etc. Clinically, osteogenesis imperfecta must be managed by an interdisciplinary medical team, since patients may present a clinical picture ranging from mild to lethal. In the first place, it is imperative to provide health care to avoid fractures, exercises to maintain muscle mass, exercise to improve motor skills, skincare by specialized dermatologists, etc.

The disease 'osteogenesis imperfecta' is caused by the neonate inheriting it

from either of the parent because it's a genetic disorder. The health care

provider should teach the parent about how to prevent the effect of having

such disease such as bone fractures.

Osteogenesis imperfecta is a genetic disorder inherited by offspring from

their parent. The disease involves individuals having very  brittle bones which are easily broken. The nurse should teach the parent to adopt bone strengthening steps such as adequate calcium intake and physiotherapy.

From left to right, the correct order of the minerals from the least hard to the hardest is ⇒ Graphite, Talc, Gypsum, Calcite, Fluorite, Apatite, Magnetite, Pyrithe, Feldespat, Quartz.

Theoretical frame:

Hardness is one of the physical properties of minerals and is a significant one when identifying and recognizing them.

Hardness measures the resistance level of a surface to abrasion. In the specific case of minerals, it measures how minerals resist being scratched or penetrated.

The hardness level is determined by an attempt to scratch or produce a mark on an unmarked surface using sharp elements, such as nails, copper coin, glass, or a steal knife. Notice that these elements also vary in their hardness.

There are different methods used to define hardness, and they are not comparable to each other. The Mohs hardness method defines an ordinary qualitative scale that characterizes the mineral according to their resistance to being scratched by a harder element.

According to the Mohs hardness scale, the level in which the given minerals are placed is as follows,

Answer:

The specific heat capacity represents the amount of energy, in joules, that it takes to raise the temperature of one gram of a given substance by one degree Celsius. Put more simply, the amount of energy it takes to raise a quantity of water by one degree Celsius would raise an equivalent quantity of sand by a little over 14 degrees. Likewise, sand does not need to lose nearly as much energy as water to produce equivalent cooling. Since it "holds" a lot less energy, it cools down much faster than sand.

Indeed, liquid water has an unusually high specific heat capacity. Because it is much less prone to temperature swings than other common substances, large bodies of water often work to moderate temperatures in a region. This helps to explain, for example, why average temperatures fluctuate very little over the year in San Francisco, a cit

Answer:

The overall purpose of the light-dependent reactions is to convert light energy into chemical energy. This chemical energy will be used by the Calvin cycle to fuel the assembly of sugar molecules. The light-dependent reactions begin in a grouping of pigment molecules and proteins called a photosystem.

The light-dependent reactions convert light energy into chemical energy. The goal of the light-dependent reactions of photosynthesis is to collect energy from the sun and break down water molecules to produce ATP and NADPH. These two energy-storing molecules are then used in the light-independent reactions.

Answer:

Leave rise and floating depends on the production of oxygen.

Explanation:

The leaves rises due to consumption of oxygen which is produced during photosynthesis. Floating of leave occurs due to production of oxygen in the process of photosynthesis. The leaf discs float faster if the rate of photosynthesis is increases because oxygen production is also increases while the leaf discs float will be slower if the rate of photosynthesis is decreased due to low production of oxygen.

The incorrect statement according to the question is “Active transport requires a cell's energy” option (a)  is correct.

Active transport is a cellular process that moves substances against their concentration gradients, from areas of lower to higher concentration. This movement of solutes against the concentration gradient necessitates energy expenditure by the cell. Active transport often involves the use of carrier proteins or pumps embedded in the cell membrane, which undergo conformational changes to transport substances across the membrane.

This energy is primarily provided by ATP hydrolysis, a process that releases energy from ATP molecules. In contrast, passive transport processes, like diffusion and facilitated diffusion, do not require energy expenditure and move substances along their concentration gradients. Thus, active transport distinctly relies on the cell's energy to function, option (a) is correct.

Answer:

The loop of henle is a part of the renal functional unit.

This handle has an ascending part and a descending part.

In the descending loop, the urine that is formed inside enters a hypotonia, since a large amount of water is absorbed and the concentrations of solutes in the urine decrease, thus generating a hypoosmolar solution, that is, with less molarity.

In the ascending loop of henle, the opposite arises, ionic channels appear that increase the concentration of solutes, this is how the urine that runs through the interior of the ascending loop of henle becomes hyperosmolar.

Hyperosmolarity is the increase in concentrations of solutes, and the increase in molarity of the solution, which in this case would be urine.

Explanation:

A very important fact is that urea is absorbed in the ascending henle loop.

Answer:

The purine ring is built onto ribose-5-phosphate of PRPP for its de-novo nucleotide biosynthesis, while the ring structure of the pyrimidine bases are synthesized separately and then coupled to ribose-5-phosphate via the C-N glycosidic bond.

Explanation:

In the de novo synthesis of nucleotides, their metabolic precursors such as aminoacids, ribose-5-phosphate, CO₂ and NH₃ are used as starting materials.

In purine  nucleotide synthesis, the ring structure is built up on ribose-5-phosphate of PRPP by addition of one or a few atoms one at a time starting with the amino group donated by glutamine until the first intermediate inosinate is synthesized.

In pyrimidine ring synthesis, orotate is first synthesized from carbamoyl phosphate and aspartate, and then is attached to ribose-5-phosphate of PRPP, before it is then converted to the common pyrimidine nucleotides starting from uridylate.

Answer:

a. It is a hormone that acts upstream in the signaling pathway (i.e., acting as a ligand by binding to cell receptors)

b. Dopamine-mediated pathways  

Explanation:

It is well known that many cellular transduction pathways are activated via binding of signaling molecules (ligands) to receptors capable of triggering signaling cascades into the cell. For example, dopamine is a signaling hormone (neurotransmitter) involved in diverse brain processes (i.e., motor control, emotional response, etc). It is a neurotransmitter that binds to dopamine receptors and then stimulates the enzyme adenylate cyclase in a process that subsequently activates the production of the second messenger cyclic adenosine monophosphate (cAMP). Finally, cAMP acts as an intracellular signal transductor that play roles in many biological processes by transferring into the cell the effects of dopamine.
