One gene pair can influence other gene pairs, with their combined activities producing some effect on phenotype; this called ________________. In Labrador retrievers, one gene pair codes for the quantity of melanin produced while another codes for melanin deposition. Still another gene locus determines whether melanin will be produced at all--lack of any produces an albino (recessive).

Answers

Answer 1

Answer:

Epistasis

Explanation:

Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants

In Genetics, a gene pair has the ability to influence other gene pairs based on their combined activities which produces some effect on phenotype; this is called epistasis.

eople that have a single allele (gene copy) for sickle cell anemia are typically not sick from the disease and are said to be carriers of sickle cell trait. These people will more often live in the malaria belt of sub-Saharan Africa. The most likely explanation for this is ________. malaria is a cause of sickle cell trait people with sickle cell trait have a better chance of surviving malaria sickle cell trait is passed on to the biting mosquitoes as malaria There is no correlation between a single allele for the pathology and the ability to survive or fight malaria.

Answers

Answer: people with sickle cell trait have a better chance of surviving malaria.

Explanation:

Malaria is a very prevalent disease in the malaria belt of Sub-Saharan Africa which includes much of western and central Africa. The people here have therefore grown to have better immunity to malaria by developing the sickle cell trait.

This has helped them survive both malaria and sickle cell anemia which doesn't affect them even though they carry the sickle cell trait.

The celiac ganglion ________. Group of answer choices is located near the base of the superior mesenteric artery arises from the greater splanchnic nerve projects postganglionic fibers that innervate the small intestine and the kidney and urinary bladder arises from the lesser splanchnic nerve arises from the lumbar splanchnic nerve

Answers

Answer:

The correct answer is ''arises from the greater splanchnic nerve''

Explanation:

The greater splanchnic nerve or great adrenal nerve, originates in the thoracic sympathetic chain from vertebral levels T5 to T9 (T10). It runs over the bodies of the thoracic vertebrae and as it descends it becomes more anterior. It enters the abdomen crossing the diaphragmatic pillar and ends at the celiac plexus. The upper part of each celiac ganglion continues with the greater splanchnic nerve. The collateral or prevertebral ganglia innervate the abdominal and pelvic organs and viscera. The celiac ganglion receives preganglionic fibers from T5 to T12 and innervates the stomach, liver, pancreas, gallbladder, small intestine, spleen, and kidneys.

In the Avery, MacLeod, and McCarty experiment, the transforming extract from virulent bacteria was treated with DNase, RNase, or protease before being mixed with nonvirulent bacteria. The appropriate control for this experiment is to treat the transforming extract from heat-killed virulent bacteria with:

Answers

Answer:

Nothing

Explanation:

A. Control variables generally entail little or no system change. To see if the method worked, the researchers required a positive control in which the heat-killed virulent bacteria invariably transformed the non-virulent microorganisms. This positive control involves adding "nothing" to both the heat-killed virulent bacteria before mixing them with the non-virulent bacteria.

In paragraph form (automatic 1-pt deduction if not), explain the evolutionary benefits of sexual reproduction as a means of increasing variation. Be sure to include (a) at least two ways in which sexual reproduction impacts genotype (i.e. genetic effects), and (b) two ways in which sexual reproduction may affect phenotype (i.e. trait effects).

Answers

Answer:

See explanation

Explanation:

According to the theory of evolution,species which are better adapted to their environment tend to survive and reproduce in a population passing on these favourable characteristics to their offsprings.

During sexual reproduction, genes can be arranged in new ways from chromosomal crossing over and recombination. This introduces new gene combinations(genotype) and ultimately variation in the population.

This variation may also lead to the observation of new phenotypes in the population.

Hi, guys so I'm doing an experiment and need help finding out the types of variables. In my experiment, I am using a narrow straw, a wide straw, and some colored water to find out how different variables affect capillary action. I'm trying to find out what is the controlled variable, independent variable, and dependent variable.

Answers

Answer:

Controlled variable=coloured water

Dependant variable=amount of water

Independant variable=narrow and wide straw

Explanation:

Have a nice day

Answer:

The controlled variable is straws. Independent it the water and dependent is the capillary action.

Explanation:

The Independent variable is the water because its not chaninging thorughout the experiment and has no conqueunces on the other varibales.  The controlled is the straws because you are controlling the different diameters in which the straws are (narrow/wide). Then as you change your controlled variable your dependent varible will change- which is the affect on capillary action.

It is believed that the ratio of cyclic electron transport to Z-scheme photosynthesis changes in response to metabolic demands. If a plant were actively engaged in a large amount of reductive biosynthesis, requiring NADPH, how would it alter these processes compared to a plant just performing the Calvin cycle to produce glucose

Answers

Answer:

The correct answer is (b) More Z-scheme photosynthesis, less cyclic photophosphorylation

Explanation:

Z-scheme is the schematic flow of the electrons from water to NADP+ and as it connects the two different photosystems that look like z in the diagram it is termed as Z-scheme of photosynthesis. The ratio of cyclic electron transport to Z-scheme photosynthesis alters as per the metabolic requirements. In the question, it is given that If a plant were actively engaged in a large amount of reductive biosynthesis, requiring NADPH, then it will acqiuire more z-scheme photosynthesis compared to a plant just performing the Calvin cycle to produce glucose.

Answer:  More Z-scheme photosynthesis, less cyclic photophosphorylation
