Which of these is another name for mechanical weathering?

The concept of aging as a result of cellular duplication errors is based on the fact that the body's ability to make new cells t

babunello [35]

Answer:

Through Mutation

Explanation:

Since our cells are able to produce exact copies of themselves. Thus, until unless some mutation has occurred and affected the ability of the cells to produce exactly similar duplicates copies of the parent cell, there is no way that an individual gets aged.

Since, mutation affects the mitochondrial DNA it is pretty sure that a mutated cell has affected the longevity of a normal cell and then that mutated cell has produced million other mutated aged cell by replicating itself

SSSSS [86.1K]

Answer:

1), Diverticulitis

2) Lack of Lactase

3) Bacterial infections

Explanation:

-Diverticulitis is a condition in which the diverticula become inflamed. This woman has diverticulitis due to the inflammation of her diverticula.

-Lack of lactase (lactose intolerance); add lactase drops to milk before drinking it.

-Appendicitis is caused by bacteria infection. If untreated, bacterial proliferation may cause the appendix to rupture, resulting in contamination of the peritoneal cavity with feces and life-threatening peritonitis.

A hypothetical three-step metabolic pathway consists of the intermediates W, X, Y, and Z, and the enzymes that catalyze the reac

GenaCL600 [577]

Answer:

ZBWCYAX

Explanation:

Equation for the intermediates: Z↔W↔Y↔X

1) B catalyzes the breakdown of Z, therefore inhibiting B leads to the build up of Z.

2) If enzyme C is inactive then the organism will not receive Y to grow, thus Y is a by-product of C.

3) If A is inhibited then W, Y and Z build except for X, thus it make sense that A catalyzes a reaction that leads to X as a by-product.

4) Inhibiting C leads to the reaction toward making Z and W, thus it catalyzes the breakdown of C directly and Z indirectly.

the eyeless gene is required for eye formation in drosophila. it encodes a homeodomain. a. what would you predict about the bioc

Arte-miy333 [17]

<h3>Briefing:</h3>

In Drosophila, the eyeless gene is necessary for the development of eyes. Given that it encodes for a homeodomain, its protein may have a role as a transcription factor that binds DNA in a specific sequence. In situ hybridization can be used to study the gene's mRNA expression pattern, and immunological methods can be used to study the protein.

A. Since the eyeless gene in Drosophila encodes for a homeodomain, one potential use for its protein is as a DNA-binding transcription factor that binds to specific DNA sequences.

B. As implied by its function, the eyeless gene should be expressed in the Drosophila cells in charge of eye formation. In situ hybridization of the gene's mRNA expression is one potential test to find the gene. The protein can also be seen via a variety of immunological and staining methods. It is possible to do gene deletion experiments to see if Drosophila will retain its eyes or go blind. Additionally, genetic engineering can determine whether the eyeless gene expressed in other organs can result in the creation of eyes.

C. Transgenic tests can be used to determine whether the Small eye and Aniridia genes function similarly to the fly eyeless gene. Since both of these function as master switches for the genes that create eyes, it is possible to transfer the mouse Small eye gene into Drosophila to observe whether it is expressed. These, however, are simply Drosophila eyes and not comparable to mouse eyes.

<h3>Describe DNA:</h3>

All known organisms, including many viruses, require deoxyribonucleic acid, a polymer comprised of two polynucleotide chains that coil around one another to create a double helix, to develop, function, grow, and reproduce. DNA and ribonucleic acid are examples of nucleic acids.
