In fruit flies, red eyes are dominant to green eyes. In a cross between a short-winged, green-eyed fly and a long-winged, red-eyed fly, the results were as follows: 40 percent short winged and red eyed 10 percent short winged and green eyed 10 percent long winged and red eyed 40 percent long winged and green eyed Which of the following reflects the chromosome makeup of the parents? (A) LlRr × Llrr
(B) Llrr × llrr
(C) LlRr × llrr
(D) LLRR × llrr
(E) LlRR × llRr

Answers

C) because the first fly has all recessive traits and so it would be llrr and the second fly has to have at least 1 dominant allele for the wings (Ll or LL) and for the eye color (Rr or RR) so c would be your best answer

The enzymatic breakdown of any type of food molecule is called ________.A. diffusion
B. active transport
C. hydrolysis
D. denatured

Answers

Hydrolysis occurs in the presence of enzymes (organic compounds that generally increase the rate of chemical reactions) called hydrolases.

What is the hydrolysis?

It is a basic process of digestion and consists of the addition of water molecules to polysaccharide, fat or protein by specific enzymes that convert it into glucose, fatty acid and amino acid, respectively.

Characteristics of hydrolysis

  • It consists of the conversion of large nutrient molecules into small ones that are possible to absorb.

Therefore, we can conclude that digestion consists of hydrolysis, a water molecule is introduced to break bonds in large molecules by the action of specific enzymes.

The two types of cell cycle genes that, if mutated, cause cancer cells to divide uncontrollably are called tumor suppressor genes andA. growth factors.
B. proto-oncogenes.
C. cancer genes.
D. telomeres.

Answers

Answer:

The correct answer is option B. "proto-oncogenes".

Explanation:

Tumor suppressor genes and proto-oncogenes are two types of genes that can cause the development of cancer cells if they suffer a mutation. The main difference between tumor suppressor genes and proto-oncogenes is the way they cause cancer. If tumor suppressor genes are inactivated they produce cancer cells, while if proto-oncogenes are activated is when they produce cancer cells.
Tumor suppressor genes and proto-oncogenes cause cancer cells to divide uncontrollably.

The answer is B) proto-oncogenes.

You can do this a few ways. You just have to change one A to a T. Or you can change a C to a G, and vice versa. For example, T-C-T-G-G-A-T. Or you could as do, A-C-T-G-C-A-T.

What is the greatest issue facing society that results from the development of new applications of cell technology?

Answers

The correct answer is C) how to reduce the cost of technology to make it widely available.

The greatest issue facing society, that results from the development of new applications of cell technology is how to reduce the cost of technology to make it widely available.

Stem cell technology combines the research and results of geneticists, cell biologists, and medical doctors to find new medicinal applications for distinct diseases. Scientists defined stem cells as progenitor cells that can renew themselves and multilineal differentiation. But the greatest issue facing society, that results from the development of new applications of cell technology is how to reduce the cost of technology to make it widely available. Today, that technology is very expensive and not all people can afford it.

The other options of the question were A) how technology can be used to serve the needs of most people, B) how to balance an individual's rights with meeting the needs of society, and D) how to develop as many diseases cure as possible with technology.

The greatest issue facing society that results from the development of new applications of cell technology is that it can make the arteries narrower especially for patients with heart diseases. Although cell technology has been revealed as an ideal cure for heart related diseases.
