when more than one gene controls a trait and the result is often a continuum (gradient) of phenotypes rather only two distinctive options this is called what?
when more than one gene controls a trait and the result is often a continuum (gradient) of phenotypes rather only two distinctive options this is called Polygenic Trait.
A Polygenic Trait that is influenced by two or more genes, such as height or skin tone, is referred to as a polygenic trait and Polygenic Trait characteristics of phenotypes do not follow the laws of Mendelian inheritance since several genes are involved. Polygenic Trait inheritance refers to the regulation of a characteristic by more than one gene in which the dominant allele of each gene expresses just a portion of the Polygenic Trait and the whole phenotype is only produced in the presence of the dominant alleles of all multiple genes.

The answer for the first blank is “one”.
The answer for the second blank is “dominant”.
The answer for the third blank is “gain” of function.
Proto-oncogenes need or demand only "one" allele (gene copy or variant) to be altered in order to cause cancer (changes in the deoxyribonucleic acid or DNA). One allele is all that is required for a proto-oncogene to develop into an oncogene that causes cancer. Since only one allele (or gene copy) is required to create an oncogene that induces cellular transformation and resulting in cancer, it is referred to as a "dominant" mutation. This type of mutation causes a "gain" in function since the affected cells can now divide uncontrollably and serve a new purpose.

simple diffusion requires energy to move materials through the membrane that is why it is called passive ___
Simple diffusion is energy-free, making it passive. Simple diffusion allows for the passage of small, neutral molecules like oxygen, carbon dioxide, and water through cell membranes.
Passive transport is the most basic type of transfer over a membrane. A substance diffuses over a membrane through passive transport as it diffuses along its concentration gradient without requiring any energy from the cell. While assisted diffusion needs an ATP source, simple diffusion doesn't. B. Facilitated diffusion moves materials both with and against a concentration gradient, whereas simple diffusion merely moves material in the direction of a concentration gradient.
Passive transport is a phenomena that happens naturally and doesn't require the cell to use energy to move. Diffusion is the process by which chemicals travel passively from a region of higher concentration to a region of lower concentration.

a sea anemone has radial symmetry; its touch receptors and eye spots are located all around its circular body. a deer has large eyes and ears and a sensitive nose, all of which are clustered at the head end of its body. which difference in these two organisms most likely accounts for this difference in the location of sensory organs?
The difference in body shape between a sea anemone and a deer is the most likely cause of the difference in the location of their sensory organs. Sea anemones have radial symmetry, meaning they have a circular body with equal parts radiating outward from the center. This structure allows the anemone to have touch receptors and eye spots located all around its body.
In contrast, a deer has a body that is elongated and asymmetrical. It has a head at one end and a tail at the other. The deer’s large eyes, ears, and sensitive nose are clustered at the head end of its body, allowing it to have a better view of its surroundings and better detect potential threats. This arrangement is advantageous for the deer and allows it to have better survival chances by giving it a greater awareness of its environment.

Each of the following will cause an increase in blood pressure except
increased levels of ADH (antidiuretic hormone).
increased levels of angiotensin II.
increased levels of ANP (atrial natriuretic peptide).
increased blood volume.
increased levels of aldosterone.
Each of the following will cause an increase in blood pressure except increased levels of ANP (atrial natriuretic peptide).
The nerve cells in the hypothalamus produce Anti-diuretic hormone. Anti-diuretic hormone acts on the kidneys and blood vessels to lower blood pressure. Antidiuretic hormone levels above a certain threshold narrow (constrict) blood artery, raising blood pressure.
Angiotensin II increases salt, body water, and blood pressure all at once. Blood arteries become constricted (narrowed) when angiotensin II is present in high level, which increases blood pressure.
By altering cardiac output, variation in blood volume have an impact on arterial pressure. Rising blood volume leads to an increase in central venous pressure. When there is more fluid present, more of it presses against the artery walls, increasing the pressure.
The kidneys release potassium through urine when aldosterone is present. Water retention results from an increase in salt in your bloodstream. Blood pressure and blood volume are raised as a result.
ANP (atrial natriuretic peptide) is released by the heart in response to elevated blood pressure and blood salt levels. It stimulates salt excretion, reduces blood volume, and relaxes the vessel when it binds to its receptor in the kidney and blood vessels. By reducing venous compliance, atrial natriuretic peptide (ANP) lowers mean circulatory filling pressure and arterial blood pressure.

tenostosis is: a.fusion of a tendon. b.suture of a tendon. c.pertaining to a tendon. d.ossification of a tendon.
Tenostosis is the conversion of a tendon into the bone, thus the correct answer is option (D). Ossification of a tendon.
Connective tissue includes tendons. They are less flexible than other types of fibrous tissue but have considerable strength like rope and are formed of collagen fibers. Tendons' primary job is to join bones and muscles so that the body can work as it should. Tendon sheaths are tissue tubes that encircle the tendons like a tunnel and are filled with lubricating fluid. The tendon sheath shields the tendon from excessive friction and fraying. Synovial fluid covers the sheath's interior surface. The tendon can move forward and backward as a result. This indicates that the lengthy tendons are shielded as they pass through the synovial joints by tendon sheaths. When the tendon gets converted or ossifies into bone the condition is called as tenostosis.

it is experimentally determined that the percentage of adenine in the dna of a particular organism is equal to approximately 32 % 32%. what proportion of guanine would be expected in this dna?
The percentage of guanine in a DNA molecule can be determined from the percentage of adenine. Each of the four nucleotide bases that make up DNA—adenine, guanine, cytosine, and thymine—are present in equal proportions. This means that if adenine is present at 32%, then guanine must also be present at 32%.
Adenine and guanine are two of the four bases of DNA, and they are complementary bases. This means that if one is present in a DNA strand, then the other must also be present. This is due to the fact that adenine always pairs with thymine and guanine always pairs with cytosine. Therefore, if the percentage of adenine in a particular organism’s DNA is 32%, then the percentage of guanine must be 32% as well.
The complementary relationship between the two bases is an important part of DNA and its structure. The base pairs hold the DNA strand together, and if one is missing, then the entire strand can unravel. This is why it is important to ensure that all four of the bases are present in the correct proportions in order for the DNA strand to remain intact and functional.

topic 2 what is adaptive radiation? what makes it a macroevolutionary process (rather than a microevolutionary process)?
Adaptive radiation describes how species spread out over new geographic space and then adapt. In time, speciation is possible which is a maco process.
Adaptive radiation is a process in which a single ancestral species diverges into multiple new species in response to the availability of new ecological niches. This can happen when a species expands into a new geographic area with a different set of environmental conditions or when a species evolves new adaptations allowing it to exploit the latest ecological niche.
As the ancestral species adapt to the new environment and evolves traits, it may eventually diverge into multiple new species through the process of speciation. Speciation is the process by which two populations of a species become reproductively isolated from each other and evolve into distinct, genetically distinct species. This can happen through a variety of mechanisms, such as geographic isolation, behavioral isolation, or reproductive isolation.

The effect that an inhibitor of cAMP phosphodiesterase enzyme have on glucose-1-phosphate production is that it reduces Glucose-1-phosphate.
Phosphodiesterase are the enzymes which controls the intracellular levels of cAMP and cGMP. By catalyzing hydrolysis of cAMP-bound to the RIα, PDEs actively prime RIα for re-association with the C-subunit and thus are critical for signal termination in cAMP signaling. Cyclic AMP (cAMP) mediates relaxation by beta-adrenergic agonists as well as other activators of adenylate cyclase. cAMP is a second messenger, used for intracellular signal transduction. cAMP signaling in the brain is widely known for mediating numerous neural processes such as development, cellular excitation, synaptic plasticity etc.

You seal a 1 lb plant in a large container with 10 lb of soil and 1 lb of water, you unseal it a month later and take the weight again, you find the plant is now 7 pounds, the soil is 10 lb, and water is 0.5 lb. define the law of conservation of matter, with this law in mind, where do you think that the plant gained most of its new weight.
The plant could have only gained most of its weight from the water and the atmosphere within the container by photosynthesis.
What is the law of conservation of matter?The law of conservation of matter states that matter is conserved in all circumstances. They can neither be created nor destroyed but their forms can change.
With this in mind, we now know that it is not possible for the plant to have gained its weight without explanations. 1 lb plant, 10 lb soil, and 1 lb water were all sealed in a large container. The only way the plant could have gained its weight was from the soil, the water, and or the atmosphere within the container.
After a month, the weight of the soil remains 10 lb. Thus, it is now sure that the plant did not gain any of its weight from the soil. The water is now 0.5 lb. This means that the plant has gained 0.5 lb from the water while the remaining weight gained by the plant can be traced to the atmosphere within the container.
This is explainable if the plant photosynthesized while sealed in the container. During photosynthesis, the plant would have gained more matter as a result of fixing carbon dioxide in the atmophere within the container into carbonhydrate with the help of water.
