Why do cells continue to divide in adult organisms?

Biology
2 answers:
Mariana [72]3 years ago
6 0

Answer:

Although most of the tissues in adult organisms maintain a constant size, the cells that make up these tissues are constantly turning over. Therefore, in order for a particular tissue to stay the same size, its rates of cell death and cell division must remain in balance.

Explanation:

There are two main reasons why cells divide rather than continuing to grow larger and larger: The larger a cell becomes the more demands the cell places on its DNA. If the cell grows too large, it will have trouble moving enough nutrients and wastes across the cell membrane. Why does cell division remain important to an adult organism even after it is fully developed? It remains important because cells are renewed and wounds are healed in the process. When cells stop dividing to specialize in structure and function. When cells undergo programmed cell death.

1.Consider the model above compare the DNA sequence of the model and abnormal CFTR gene explain the differences and similarities
Mumz [18]

Answer:

1.Their similarities are that they both contain the codons for the following amino acids Isoleucine (ATC), glycine (GGT) and valine (GTT).

Their differences are:

a. Their codons for the second isoleucine molecule is different, ATC in the normalgene compared to ATTinnthe abnormal gene.

b. The codon for the amino acid phenylalanine is lacking in the abnormal gene.

2. The abnormal structure of the CFTR protein is because the amino acid phenylalanine is lacking in the polypeptide chain of the that region of the protein. This would result in an error in the secondary and tertiary structure of the protein.

3. The mutant protein would not be able to perform its function of channelling chloride ions across the membranes because the protein molecule is not properly folded for this function.

Explanation:

1. The DNA sequences of the normal CTFR gene and that of the abnormal CFTR gene shows some similarities as well as some differences.

Their similarities are that they both contain the codons for the following amino acids Isoleucine (ATC), glycine (GGT) and valine (GTT).

Their differences are:

a. Their codons for the second isoleucine molecule is different, ATC in the normalgene compared to ATTinnthe abnormal gene.

b. The codon for the amino acid phenylalanine is lacking in the abnormal gene.

2. The abnormal structure of the CFTR protein is because the amino acid phenylalanine is lacking in the polypeptide chain of the that region of the protein. This would result in an error in the secondary and tertiary structure of the protein.

3. The mutant protein would not be able to perform its function of channelling chloride ions across the membranes. This is because the protein molecule is not properly folded for this function. As illustrated by the model, while the normal protein can open for ions to move through, the mutant protein cannot.

Readme [11.4K]

Answer:

C. It involves urate crystal formation within the articular tissues

Explanation:

Gout is described as a sudden, severe attacks of pain, swelling, redness and tenderness in the joints most often at the base of the big toe.

When urate crystals formed in your joint, it causes the inflammation and intense pain of a gout attack. When you have high levels of uric acid in your blood, urate crystals can form.

Uric acid is produced in your body when it breaks down purines — substances that are naturally found in your body.

Purines are also found in some foods, like steak, meats and seafood. Alcoholic beverages, especially beer, and drinks sweetened with fruit sugar (fructose) also promote higher levels of uric acid

A. Fisheries are badly managed.

B. Fisheries deplete mass amounts of fish to use as fish meal.

C. Fisheries often use a large amount of chemicals.

D. Fisheries can alter the genetic pool.

E. Many fisheries use unsustainable fish-feed ingredients.

<h3>What is Mike Velings talks about?</h3>

Industrial aquaculture has had a wide range of negative effects on the environment, including the overfishing of wild fish to feed carnivorous farmed fish and the escape of farmed fish from their containment, which endangers local wild fish populations.

Lastly, in the words of Mike Velings, We are approaching a worldwide food crisis, he said. At our current rate, we are already taking more fish from the ocean than it can naturally replace, despite the fact that almost 3 billion people rely on the ocean for their food. Mike Velings, an entrepreneur and conservationist, offers a solution in this fact-filled, eye-opening talk: the practice of farming fish. "We need to stop hunting the ocean and start farming it,"
