What are the 3 stages of aerobic respiration?

Strike441 [17]

Answer:

Cellular respiration uses energy in glucose to make ATP. Aerobic (“oxygen-using”) respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport. Please mark brainliest :)

When a population has a gene with two alleles circulating, how many possible genotypes are there?

marissa [1.9K]

Its so simple. Two alleles means three genotypes.
consider a gene has two alleles A(blue eyes) and a(brown eyes)
possible combinations:
1. AA - Homozygous dominant -Blue eyes.
2. Aa - Heterozygous - Blue eyes.
3. aa - Homozygous recessive - Brown eyes.

Which of the following statements about translation is FALSE?

myrzilka [38]

Answer:

e. All of the above are False.

Explanation:

A tRNA is a transfer RNA that carries amino acid from the cell pool to the mRNA-ribosome complex. The anticodon sequence of tRNA is complementary to the mRNA codons and bind to the respective amino acids. None of the tRNA has anticodon for stop codons and therefore, as soon as the ribosome reaches stop codon, protein translation terminates.

AUG is the initiation codon for protein synthesis and codes for methionine when present at a site other than the start site. The initiation codon is often preceded by an untranslated sequence, also called leader sequence. The ribosome moves along the mRNA in 5' to 3' direction in a GTP dependent manner to facilitate elongation of the polypeptide chain.

Rank from the first to the last steps to describe the correct order of events of erythrocyte death.

timama [110]

Answer:

1. erythrocyte becomes trapped in the sinusoids of spleen.

2. Spleen macrophages digest the erythrocytes.

3. Hemoglobin is broken down into amino acids, iron and bilirubin.

4. Iron ions and amino acids are recycled to make new hemoglobin in red bone marrow. Bilirubin is sent to liver for excretion.

Explanation

Aging erythrocytes are trapped in the sinusoids of the spleen, where they are digested by macrophages. Within the macrophage, hemoglobin is broken down into amino acids, iron ions, and bilirubin.

Iron ions or heme ion and amino acids then move through the blood to the bone marrow, where they are recycled and used to create new hemoglobin. Bilirubin travels with the help of the blood to the liver, where it is modified and then excreted.

thus, the correct order is :

1. erythrocyte becomesrapped in the sinusoids of spleen.

2. Spleen macrophages digest the erythrocytes.

3. Hemoglobin is broken down into amino acids, iron and bilirubin.

4. Iron ions and amino acids are recycled to make new hemoglobin in red bone marrow. Bilirubin is sent to liver for excretion.

The green data point at June 2011 shows a proportional change of about________ , which means that the native fish population____

Orlov [11]

Answer: The appropriate information that will be used to fill the blanks includes the following respectively:

-1.7

- increased

-70%

- 0.5

- decreased

- 50%

Explanation:

The green (topmost) data point at June 2011 shows a proportional change of about 1.7, which means that the native fish population INCREASED by about 70 percent when 95 percent of the lionfish were removed. In contrast, the orange data point at June 2011 shows a proportional change of about 0.5, which means that the native fish population DECREASED by about 50 percent when only a quarter of the lionfish were removed (a result that was almost the same as when none of the lionfish were removed).

The native fishes are being haunted by the lion fish, from the results, removing just few of the invasive lion fish will not make a difference. In other to help the native fish survive, many of the lion fish has to be removed.
