A collection of closely related animals or plants that share a similar genetic evolutionary history but cannot necessarily interbreed to produce fertile offspring is referred to as a _____. species genus tetraploid polyploid diploid

Answers

Answer 1

Answer:

Genus

Explanation:

Genus is a group of related plant or animal species. These group of species share a common evolutionary history which means that they are descended from a recent or distant common ancestor. These group of plant or animal species can not interbreed among themselves as the individuals of the different species can not interbreed to give rise to the fertile progeny.  

Example: Solanum is a plant genus that includes many species such as nigrum, tuberosum, etc. The plants of S. nigrum and S. tuberosum can not interbreed in nature as they belong to different species.

Why do the circulatory systems of land vertebrates have separate circuits to the lungs and to the rest of the body? View Available Hint(s) Why do the circulatory systems of land vertebrates have separate circuits to the lungs and to the rest of the body? The large decrease in blood pressure as blood moves through the lungs may prevent efficient circulation through the rest of the body. Land vertebrates are bigger and require more tubing to reach all areas of the body. The circuits increase the amount of surface area available for the diffusion of gases and nutrients in the body. Blood is pumped to the lungs to be oxygenated before being pumped to the rest of the body.

Answers

Explanation:

There are two types of circulation in mammals. The pulmonary circulation and the systemic circulation. As you might know, mammals use double circulation of blood.

The pulmonary circulation is the circulation of blood from the heart to the lungs.

While

The systemic circulation is the circulation of blood from the heart to other parts of the body.

Which two factors below make rapid and substantial blood loss life threatening? loss of immunity and loss of carbon dioxide carrying capacity loss of immunity and loss of blood pressure loss of clotting ability and loss of osmotic pressure loss of blood pressure and loss of oxygen carrying capacity

Answers

Answer:

Loss of blood pressure and loss of oxygen carrying capacity

Explanation:

If blood pressure decreases to critical levels the tissue perfusion will be seriously affected. This means that there will be limited nutrients for tissue cells and they will not be able to keep normal functions and will start dying.

If you lose your oxygen carrying capacity tissue cells will not be able to keep aerobic respiration and in a few minutes die.

Final answer:

Rapid and substantial blood loss is life-threatening due to loss of blood pressure and loss of oxygen-carrying capacity. Reduced blood pressure can impair vital organ function, leading to death. The loss of blood also reduces the body's ability to transport oxygen to cells and tissues.

Explanation:

The two factors that make rapid and substantial blood loss life-threatening are the loss of blood pressure and the loss of oxygen-carrying capacity. Rapid blood loss leads to reduced blood pressure, which can decrease perfusion to the brain and other vital organs, leading to organ shutdown and death. Simultaneously, the loss of blood also reduces the oxygen-carrying capacity. The human body cannot survive without oxygen for more than a few minutes.

When the oxygen-carrying capacity is decreased due to blood loss, the body's cells and tissues are deprived of the necessary oxygen, impairing their function or causing them to die. Therefore, maintaining both blood pressure and oxygen-carrying capacity is crucial, especially in situations involving significant blood loss.

Cells undergoing chemotaxis rely on the process of accommodation to keep moving towards higher concentrations of attractants. What protein is directly responsible for modifying the MCP and causing accommodation?

Answers

Answer: CheA

Explanation:

Cytokines and chemokines are proteins that bind to other, cells that require specific antibodies to these proteins, making them a form of communication between the system cells immune. That process by which cells are sent to move through a chemical stimulus is called chemotaxis. The internal environment is responsible for the signal transduction part received by the receivers. CheR is a relatively slow enzyme and its main function is to methylate the receptors. It is divided into two domains: one responsible for substrate identification and the other for transferring methyl groups to the receptor.

Answer:

CheR is the protein responsible of  for modifying the MCP and causing accommodation. When cells undergo chemotaxis.

Explanation:

Chemotaxis is the movement effect a certain organism suffers after being exposed to chemical stimuli. The organisms that react like this are somatic cells, bacteria, single-cell, or multicellular organisms. Now, when these organisms are in the regulation phase they accept CheR to modify the Mcp or methyl-accepting chemotaxis proteins. The McP is modified because it is needed to regulate the number of proteins required to move and maintaining the number of proteins high but not over administered. Thus, to be capable o performing chemotaxis at its most optimate level at any time.

Hormone secretion is often regulated through a negative feedback mechanism, which means that once a hormone is secreted it will cause the hypothalamus and pituitary to shut down the production of signals necessary to secrete the hormone in the first place. Most oral contraceptives are made of small doses of estrogen and/or progesterone. Why would this be an effective means of contraception?

Answers

Answer:

Oral contraceptives inhibit the secretion of gonadotropins by inhibiting the secretion of GnRH through a negative feedback mechanism.

Explanation:

Most oral contraceptive pills have combined dosages of estrogen and progesterone or one of these hormones. The estrogen and progesterone are involved in negative feedback inhibition of gonadotropin-releasing hormone (GnRH). Presence of small dosages of estrogen and progesterone inhibit the secretion of GnRH and thereby, prevents the secretion of gonadotropins (LH and FSH).  

FSH (Follicle-Stimulating Hormone) is required for maturation of follicles while LH (Luteinizing Hormone) is required for ovulation of mature follicle.  

Hence, hormonal contraceptives prevent conception by preventing follicle development and ovulation due to the absence of gonadotropins (FSH and LH).  

You are dispatched to a​ 1-year-old child with respiratory distress. En​ route, you review how to assess and treat infants with respiratory problems. Which of the following would NOT be a standard part of assessment for​ breathing?
A.
Work of breathing
B.
Mental status
C.
Chest expansion
D.
Sounds of breathing

Answers

Answer:

B. Mental status

Explanation:

Respiratory diseases are medical conditions that affect the lungs and breathing capacity, but do not alter the child's mental state, so in assessing the child's breathing, it will not be necessary to evaluate breathing work, chest expansion and sounds of the child's breath. It is not necessary to evaluate the mental states to know if the child has breathing problems.

Some breathing problems are genetic while others are caused by lifestyle or environmental factors. Common breathing problems include asthma, bronchitis, emphysema, tuberculosis and sinusitis.

DNA polymerase is responsible for adding nucleotides to build a new DNA strand during replication, proofreading to correct base pair errors, and removing and replacing RNA primers with DNA nucleotides to complete the replication process, option a is correct.

The main functions of DNA polymerase include the synthesis of DNA by adding nucleotides to a primer or a pre-existing DNA strand, and the correction of base pair errors, which is known as proofreading. During DNA replication, DNA polymerase performs these functions by reading the template strand and adding complementary nucleotides to form a new strand. If an incorrect base has been incorporated, DNA polymerase's exonuclease activity removes the wrong nucleotide, and then the correct nucleotide is added.

Proofreading is a critical function of DNA polymerase, ensuring the accuracy of DNA replication. Additional roles of DNA polymerase involve the removal of RNA primers that are initially added by primase and replacing them with DNA nucleotides. Finally, DNA polymerase also works to fill in the gaps that are left after the RNA primers are removed.

A rapid mechanism is thought to govern the localization of AQP5 in response to changes in extracellular osmolarity. If this mechanism is independent of both PKA activity and S156 phosphorylation, which of the following will most likely be observed?
(A) HEK cells exposed to the most hypertonic conditions will display the greatest degree of AQP5 membrane localization, allowing water to flow into the cells.
(B) HEK cells exposed to the most hypotonic conditions will display the greatest degree of AQP5 membrane localization, allowing water to flow into the cells.
(C) HEK cells exposed to the most isotonic conditions will display the greatest degree of AQP5 membrane localization, allowing water to flow into the cells.

Answers

Answer:

(B) HEK cells exposed to the most hypotonic conditions will display the greatest degree of AQP5 membrane localization, allowing water to flow into the cells.

Explanation:

The function of AQP5 (an aquaporin) is to allow the water to move into or out of the cell down the concentration gradient. When placed in hypotonic solutions, the internal environment of HEK cells will be hypertonic. Water always moves from hypotonic (higher water concentration) to hypertonic (lower water concentration) solution.  

Hence, the HEK cells exposed to the hypotonic conditions will localize AQP5 in their membranes to allow the water to move from out hypotonic conditions to the inner hypertonic environment.

Answers

Answer:

Results in a hairpin loop structure in RNA, AND results in the polymerase falling off the DNA template.

Explanation:

As the RNA polymerase arrives at the terminator site, it pauses. The termination of RNA transcription occurs when an RNA transcript with a self-complementary sequence is formed leading to the formation of the hairpin structure. The hairpin structure has 15-20 nucleotides.  

The hairpin structure of RNA weakens A=U base pairs in RNA-DNA hybrid and/or weakens the interaction between RNA and RNA polymerase. The overall effect is the dissociation of RNA polymerase from the complex and termination of the transcription.

A. decrease its volume
B. add organelles
C. let water out of the cell
D. all of the above

Answers

the answer to this question is D.all of the above

Answer:

D. all of the above

Explanation:

Cells increase their surface area through microvilli, which are often digitiform plasma membrane projections, ie, glove-finger shaped. They are stable or permanent type specializations on the cell surface. Microvilli enlarge the surface of the plasma membrane increasing its efficiency for exchanges with the cavity or extracellular medium.

If a cell lets water out it will lose volume. The volume of the cell is proportional to the size of the surface area, so if the cell decreases its volume it also decreases its surface area. Also, the cell cannot add new organelles.
