there are two distinct ways in which the basic body tissues become arranged during the development of a fertilized egg. in , such as insects and earthworms, the first opening to form in the embryo becomes the mouth, whereas in , such as humans and sea stars, the mouth forms from the second embryonic opening.

Answers

Answer 1

An organ is a structure made up of two or more tissue types that work together to perform a specific function.

A blastocyst is a ball of cells that develops early in a pregnancy, around five to six days after a sperm fertilizes an egg. It implants in your uterine wall and develops into an embryo, then a fetus.

Fertilization initiates the early phases of embryonic development. Fertilization is closely monitored to ensure that just one sperm unites with one egg. The zygote undergoes cleavage after fertilization to generate the blastula.

Members of major taxonomic groups of animals are classified as protostome or deuterostome based on how they grow as embryos.

what is the founder effect; what is genetic drift; bottleneck effect; genetic drift vs gene flow; what causes genetic drift; population bottleneck; genetic drift example; genetic bottleneck

Answers

Alleles alter frequency within a population owing to random sampling in genetic drift. As a result, no modifications are produced.

The transmission of alleles or gametes from one group to another distinguishes gene flow from genetic drift. When a population migrates or becomes geographically isolated, this occurs.

When a population is drastically reduced in number due to a natural disaster (bottleneck effect), or when a small group breaks off from the main population to establish a colony, genetic drift can have serious consequences (founder effect).

The sort of event that produces founder events and population bottlenecks is what distinguishes them.

A founder event happens when a small number of people is isolated from the rest of the population, but a bottleneck effect happens when the majority of the population is annihilated.

For small populations, genetic drift can result in significant genetic variety loss. A population bottleneck occurs when the size of a population is decreased for at least one generation.

at the genetic level, biological evolution is: at the genetic level, biological evolution is: natural selection. a population change over time. a change in fitness over time. a change in allele frequencies over time. an increase in fitness over time.

Answers

At the genetic level, biological evolution is a change in allele frequencies over time.

What is biological evolution?

In populations of organisms, biological evolution is the change in hereditary features through successive generations. Adaptation is a crucial evolutionary process in which natural selection modifies variance in the fitness of characteristics and species to make them better suited for survival in particular ecological settings. Therefore, understanding the mechanics of evolution requires understanding how developmental changes are mediated.

Model organisms are used frequently to study biological processes. A model organism is a species that is thoroughly researched in the lab with the hope that the findings will be applicable to various biological processes.

D. Increasing or decreasing volumes of reactants

Answers

Adding or removing a catalyst does not affect the equilibrium position of a reaction

Glycolysis is the process in which glucose is broken down to produce energy. It produces two molecules of pyruvate, ATP, NADH and water. The process takes place in the cytoplasm of a cell and does not require oxygen. It occurs in both aerobic and anaerobic organisms

Glycolysis is divided into 3 stages:

Stage 1 (Priming stage)

Stage 2 (Splitting stage)

Stage 3 (Oxidoreduction-phosphorylation stage)

Answers

Ephedrine can be easily pass with the cell membrane more than the epinephrine. Option (A) is Correct.

In reaction to stress, the adrenal medulla releases the hormone epinephrine, which is mediated via sympathetic fibers. Because the gland sits atop the kidney, the word "epinephrine" derives from the Greek words "epi," which means "above," and "nephros," which means kidney. Due to the name of its gland, epinephrine is also known as adrenaline.

For this reason, epinephrine and norepinephrine receptors are often referred to as adrenergic receptors. Based on how the adrenergic receptors responded to epinephrine, norepinephrine, and the adrenergic agonist isoproterenol, Ahlquist classified the adrenergic receptors as either or in 1948. Compared to the receptors, the receptors react to significantly lower amounts of epinephrine or norepinephrine. While epinephrine and norepinephrine affect 1 receptors in roughly similar amounts, 2 receptors are more responsive to epinephrine. Phenoxybenzamine and propanolol both inhibit the receptors.

Answers

increased blood glucose levels immediately following a meal will cause the pancreas to increase insulin secretion, but as blood glucose levels drop between meals, the pancreas will decrease insulin secretion.

In the process of digestion, insulin is secreted by the pancreas so that the sugar can be degraded and the sugar levels in the blood can be brought to normal.

When a person has recently had a meal, then the glucose levels in the blood will rise due to glucose. Hence, the pancreas will secrete more insulin to bring the sugar levels to normal.

When it has been hours after a person has taken a meal, the sugar levels in the blood decrease. Due to this, the secretion of insulin by the pancreas is decreased in order to maintain blood sugar levels.
