______ results in genetically identical daughter cells, whereas ______ results in genetically different daughter cells.

Answers

Answer 1

Identical daughter cells are produced as a result of mitosis whereas meiosis results in the formation of the daughter cells which are different genetically.

Mitosis and Meiosis are the stages of the cell cycle which can be further divided into stages called prophase, metaphase, anaphase and telophase. Mitosis results in the formation of two diploid daughter cells which genetically identical to the initial parent cell.
In the process of meiosis, the DNA gets exchanged between the chromosomes that are paired. This shuffling of DNA results in the formation of daughter cells after cell division which are genetically dissimilar.

A population of sunfish live in a lake. in ecology, that lake is classified as a habitat.

The term "habitat" encapsulates the variety of materials, biotic elements, and physical elements that exist in a place, such as to enable the life and procreation of a population.  An animal's habitat can be thought of as the outward representation of its biological niche. Thus, the term "habitat" refers to a specific species and is fundamentally distinct from ideas like the environment or vegetation assemblages, which are better described by the term "habitat-type."

Which events in meiosis are responsible for the principle of segregation? select all that apply

Answers

Separation of homologous chromosomes in anaphase 1 is responsible for the principle of segregation.

Mendel put out the law of segregation after noticing that true-breeding pea plants with opposing features produced F1 generations that all displayed the dominant trait and F2 generations that expressed the dominant and recessive traits in a 3:1 ratio. According to the law of segregation, each diploid individual has two alleles (copies) for a specific attribute. During meiosis, the two different alleles for a single gene segregate as the chromosomes divide into several gametes, resulting in each gamete acquiring one of the two alleles.The fundamental tenet of the rule is that copies of genes separate or segregate, resulting in just one allele being passed on to each gamete.Hence in anaphase 1 when the homologous chromosomes are pulled apart the alleles also segregate.

If a discard tube is required by your facility, what is an appropriate discard tube to collect prior to filling tubes for coagulation testing?

Answers

Red non-additive is an appropriate discard tube to collect prior to filling tubes for coagulation testing.

What is the process of coagulation?

Blood thickens into a gel-like consistency during coagulation, which is the process by which it goes from being a liquid to become solid. Hemostasis is a bigger process that includes coagulation and is how the body controls when and how much bleeding occurs. The gel plugs seal blood artery leaks and stop blood loss. Coagulation factors, calcium, and phospholipids are necessary for the process. The liver produces coagulation factors (proteins).

The 3 stages of coagulation:

Blood vessel constriction.The development of a transient "platelet plug."The coagulation cascade is activated.

Samples of coagulation must be fully filled, but not overfilled. The minimum fill line is frosted and used to identify tubes. For accurate test results, the blood to anticoagulant ratio must be kept at 9 to 1.

Answers

A gene region where there are two distinct alleles present. One normal allele, one mutated allele, or two distinct mutated alleles can make up a heterozygous genotype.

Combinations of offspring:

Let's say that the letter S stands for a solid coat and the letter s for a spotted coat. This indicates that the genomes of the two heterozygous cocker spaniels are Ss. As a result, the likelihood of the progeny having a solid coat (SS and Ss) is 75% and a spotted coat (SS) is 25%.

There is a 25% chance that the firstborn puppy in the first litter will have spotted fur. The likelihood that 4 of the 5 remaining pups will have spotted fur is 1/4 x 1/4 x 1/4, or 1/256. Calculate the likelihood that the second litter will have 6 pups with solid fur by multiplying 3/4 by 6, which equals 64/4096 or 1.5% The probability that the second litter will contain 1 pup with spotty fur is 25%.

Answers

The group of vascular disorders that are marked by blood vessel necrosis and inflammatory injury is Cutaneous necrotizing vasculitis.

Vasculitis involves inflammation of the blood vessels. The inflammation can cause the walls of the blood vessels to thicken, which reduces the width of the passageway through the vessel. If blood flow is restricted, it can result in organ and tissue damage. There are many types of vasculitis, and most of them are rare.

Cutaneous necrotizing vasculitis is a not uncommon disorder characterized by an inflammation of the blood vessel walls and skin lesions. These skin lesions may be flat and red (macules), nodules, or more substantial hemorrhages under the skin (purpura).

Colchicine, hydroxychloroquine, dapsone, or a short course of low-dose corticosteroids can be tried. Sometimes, stronger immunosuppressants (eg, azathioprine, methotrexate) are used, particularly if lesions ulcerate or if corticosteroids must be taken indefinitely to control symptoms.

The residual air is the amount of air remaining in the lungs after a forced expiration. The volume of air exchanged during normal breathing is called the tidal volume. After a normal inspiration, the amount of air that can then be inspired forcefully is called the inspiratory reserve volume. The total lung capacity minus the residual volume equals the vital capacity. The vital capacity minus the expiratory reserve volume equals the inspiratory capacity. The effects of obstructive disorders, such as asthma or emphysema, may be determined by measuring rapid exhalation with a spirometer.

The lungs are the main organs of the respiratory system. These lungs are also the site of exchange of gases. The air is inspired through the nostrils and this air then reaches the lungs, where the oxygen from air is trapped in the alveoli.

Genes that are physically adjacent to one another on the same chromosome are said to be linked genes because they are more likely to be inherited together. Chromosomes are recombined during meiosis, causing gene swaps between homologous chromosomes. Together, they are inherited. For instance, certain eye and hair colors are inherited jointly and are related genetically.By dividing the total number of recombinant gametes by the total number of gametes, X 100 the linkage distance is determined.

Thus here the total recombinant genes are 6 and the total number of gametes or offspring are 100 so,
