Sam is out for a long run on a hot day. He is dehydrated and does not have water with him. As he tries to maintain a high exercise intensity, his body is likely experiencing the dual cardiovascular demand.Which two factors make up this demand?
a. The need to pump additional blood to the surface of the skin b. The need for additional hydration c. The need for more ATP d. The need to produce more sweat e. The need to pump additional blood to working muscles f. The need for additional blood plasma

Answers

Answer 1

Answer:The dual cardiovascular demands includes: Option A (The need to pump additional blood to the surface of the skin.) And

Option E (The need to pump additional blood to working muscles)

Explanation:

When an individual is performing exercise under the hot atmosphere, the following demands are required:

--> there would be physiological increased demand of the skin to prevent further dehydration .

--> there would be increased energetic demands for muscular activities.

1.) The blood flow to ACTIVE MUSCLES during prolonged exercise under a hot day.

There is increase in carbon dioxide and hydrogen ions, decrease in oxygen levels will cause the smooth muscles of the blood vessels located at the active muscle sites to relax. This enhances the in flow of blood supply oxygen which is needed for the generation of Adenosine triphosphate (ATP) for energy. This requires a greater cardiac pumping capacity.

2) The flow of blood to the skin during during prolonged exercise in a hot day.

To avoid dehydrations during exercise which occurs through the lungs and skin, there is increased cardiac output to remove excess heat generated through thermoregulation of cutaneous circulation.

Stars form from what celestial objects ?

Answers

  Stars are born within the clouds of dust and scattered throughout most galaxies. A familiar example, a dust cloud is the Orion Nebula. Turbulence deep within these clouds gives rise to knots with sufficient mass that the gas and dust can begin to collapse under its own gravitational attraction. Stars begin their lives as clouds of dust and gas called nebulae. The gravity of a passing star or the shock wave from a nearby supernova may cause the nebula to contract. Matter in the gas cloud will begin to coalesce into a dense region called a protostar.

An amoeba expels large particles by what process?

A. Diffusion
B. Endocytosis
C. Exocytosis
D. Osmosis

Answers

D, best explains the question.

An amoeba expels large particles by EXOCYTOSIS (Option C).

Exocytosis is the process by which large macromolecules are released from the cytoplasm to the cell exterior.

Exocytosis occurs via secretory regions of the cell membrane which are able to excrete waste products and other large macromolecules.

Conversely, endocytosis is the inverse process by which a cell takes macromolecules from its surrounding environment.

The types of active transport that amoebas use to transport macromolecules are endocytosis (in) and exocytosis (out).

In conclusion, an amoeba expels large particles by EXOCYTOSIS (Option C).

An anatomy and physiology student, is asked to breathe through a 3-foot long glass tube. What effect does this action have on his blood pH, urine pH, and respiratory rate?

Answers

Answer:

If a student breathes through a 3 feet long glass tube it will affect the physiology of the student in various ways such as a change in blood pH, urine pH, and rate of respiration.

It will result in an increase in the normal volume area of the trachea and bronchi as it is a closed system as a face mask. The increase in this dead volume are will result in double the volume of CO2. Decrease the pH of the blood.

When asked to breathe through 3-foot long glass tube there would reduced oxygen available to the tissue (hypoxia) which had the following effects discussed below.

Hypoxia occurs when there is reduced oxygen available to the body tissues.

When asked to breathe through a 3-foot long glass tube, it can lead to hypoxia.

The effect of hypoxia include the following:

Blood pH: Due to increase in anaerobic respiration in the tissues, lactate production increases leading to a fall in blood pH.

Urine pH: Hypoxia leads to increase in renal sodium excretion which helps acid-base balance of the body fluid.

Respiratory rate: There is significant increase in respiratory rate to compensate for the decreased tissue oxygen levels.

Answers

Answer:

in a predictable pattern!!

Development typically occurs in a predictable pattern; however, the OTA  understands the influence of dynamic systems, including internal and external variables, on development.

Developmental patterns often follow a general sequence and progression across individuals, encompassing milestones in physical, cognitive, social, and emotional domains. This predictable pattern provides a framework for understanding typical development and helps identify potential delays or challenges in various age groups.

Internal variables refer to the individual's genetic makeup, temperament, and personal characteristics, which contribute to the uniqueness of their development. Every person has their own pace and style of progressing through developmental stages, and the OTA considers these individual differences in tailoring interventions and support.

Answer:

The data in the Venn diagram suggest about the realized niches of the cattle and buffalo and their ability to coexist with evidence is discussed below in detail.

Explanation:

2.

From the graph, it is observed that Cattle and Impala have the most overlay in their nutrition.

3.

When Sorensen's index worth is more like 1, there is a contestant among animals for their food manner needs.

From the Venn diagram, we recognize that Cattle and Impala have the most overlay in their nutrition. Also, Sorensen's index worth = 0.82 (closer to 1 concerning other partners.

4.

Sorensen's index for Buffalo and Cattle is 0.48 (cheapest among these 3 partners). So, they are less competitive. So, they can persist and generate easily.

A gene carries the _________ for a trait.

Answers

Answer:

A gene carries the information for a trait.

Explanation:

Genes carry the information that determines your traits (say: trates), which are features or characteristics that are passed on to you — or inherited — from your parents. Each cell in the human body contains about 25,000 to 35,000 genes.

A gene carries the information for a trait.

What is gene?

The fundamental structural and operational component of heredity is a gene. DNA is the component of genes. Some genes serve as blueprints for the synthesis of proteins. Many genes do not, however, code for proteins.

A few hundred DNA bases to more than 2 million bases make up a gene in a human. Humans are thought to have between 20,000 and 25,000 genes, according to the Human Genome Project, an international research project that aimed to decipher the human genome's sequence and catalog its genes.

Every gene is present in two copies, one from each parent, in every individual. The majority of a person's genes are the same in all persons, but a tiny fraction (less than 1% of the total) are slightly different.

Therefore, A gene carries the information for a trait.

Duchenne Muscular Dystrophy (DMD) is an X-linked recessive trait that causes muscular weakness, deterioration of muscle tissue, and loss of coordination. The allele for DMD is represented by Xd and the normal allele is represented by XD . Neither parent has DMD, but both of their sons express the trait. What are the genotypes of the parents?

Answers

Answer:

The correct answer is - XDXd and XD Y

Explanation:

Sex-linked disorders are the disorders that are expressed only when there is two copy of the mutated allele or have not masked by the dominant allele of the gene. In DMD, the dominant allele is XD and the mutated allele is Xd. To express it there are the following genotype possible-

in women XdXd, and in men XdY, so these two genotypes are not possible for the parents in this case. If a mutated allele is present with the dominant allele it will be considered as carrier women but diseased will not be found in them.

So the correct genotype would be

mother: XDXd ( a carrier woman)

father : XDY (normal man)
