Answer:

The scientist can insert the DNA into bacteria

Explanation:

Bacteria are frequently used in biotechnology to make proteins scientists are interested in. If they know the gene and the sequence of the gene that makes the protein product, they can insert that gene into a vector that will cause the bacterial transcription and translation machinery to produce the protein.

Firsts scientists clone their DNA of interest into a vector, a circular piece of DNA that the bacteria will transcribe. The vector is then introduced to competent bacterial cells. (Competent means there are holes in the bacterial membrane that allow them to uptake the gene and vector).  

Once the vector is in the bacteria, it (and the gene of interest) will be transcribed and translated as it would in the chicken liver.

On average, activated yeast cells divide once every 120 minutes; that is, each individual cell divides into two individual cells
astra-53 [7]

Answer:

The correct answer is 4,960,000

Explanation:

If a yeast cell divides into two yeast cells in 120 minutes that means a yeast cell needs 2 hours to get double. So according to the question 2 hours ago a yeast colony consisted of 310,000 cells that means the present colony should have 620,000 cells.

So after six hours from now, this population will divide three times in six hours because the generation time of yeast cell is 2 hour and each time the number of cells will double.

Therefore, in first time the number will increase to 1,240,000(620000*2), the second time the number will increase to 2,480,000(1240000*2) and after final division, the number will be 4,960,000(2480000*2).

Therefore after 6 hours from now, the approximate number of yeast cells will be 4,960,000.

Answer: Peroxisome

Explanation:

A peroxisome is a membrane-bound organelle usually found in the cytoplasm of almost all eukaryotic cells. It is an oxidative organelle.

Eukaryotes are comprised of one or more cells that contain peroxisomes. The organelles were first discovered by the Belgian scientist Christian de Duve, who was same person that discovered lysosomes.

Peroxisomes contain a variety of enzymes, which primarily function together to get rid of toxic substances in the cell, and in particular, hydrogen peroxide which a common byproduct of cellular metabolism. These organelles contain enzymes that convert the hydrogen peroxide to water, making it remain safe in order to be released back into the cell. Some types of peroxisomes, such as those in liver cells, detoxify alcohol and several other harmful compounds by transferring hydrogen from the poisons to molecules of oxygen (known as oxidation). Other perixosomes are more important for their ability to initiate the production of phospholipids, which are typically used in the formation of membranes.

Alternation of generations in plants refers to the fact that plants make a multicellular haploid structure (free living in some
Yuki888 [10]

Answer:

True.

Explanation:

The life of a plant alternates between haploid and diploid generations. From a fully matured diploid plant (2n) which is known as sporophytic generation a lot of spores which are haploid are produced by the process of meiosis. By the process of mitosis, these spores then develop into new multi-cellular plant which is also haploid just like spores (n), this phase of plant life cycle is known as gametophytic phase. This haploid plant is capable of producing gametes (n) which are also haploid. When two such gametes from the same or different plant fuse with each other a diploid cell is produced which is known as zygote (2n). This zygote subsequently divides and grows into a diploid plant which is a part of sporophytic generation. This is how the entire life cycle of various plants alternate between gametophytic and sporophytic phase.

This diploid plant then later again produces spores and the cycle of reproduction goes on in the same manner as described above.
