A certain strain of bacteria divides every 2 hours. If a colony is started with 80 bacteria, then the time t (in hours) required

for the colony to grow to N bacteria is given by t = 2 log(N/80) log 2 . Find the time required for the colony to grow to two million bacteria.

Answer:

The time required for the colony to grow two million bacteria is 29.22.

Explanation:

Time required for the colony to grow can be calculated by the following equation:

t=2log(N/80)/log 2.

Here t is time, N = 2 million  (require bacteria population).

t=2log(2,000,000/80)/log2

t ≈ 29.22

Time taken by bacteria to grow is 29.22.

miskamm [114]

Answer:

D) observation that certain tumor-suppressor genes and oncogenes are involved in a sequential manner in the development of colon cancer

Explanation:

Cancer is defined as the abnormal growth of cells of the body. These cells multiply/replicate without control thereby forming a lump or tumor.

Cancer growth has 5 stages and they go though different multi level steps.Different finding backs this up and it includes observation about certain tumor-suppressor genes and oncogenes being involved in a sequential manner in the development of colon cancer.

The ability of the human body to break down the red color in beets is controlled by an autosomal dominant allele. The inability
Zinaida [17]

Answer:

Explanation:

<em>Let the ability to break down the red color in beets be represented by the allele </em><em>B</em><em>. The inability would be represented by the allele </em><em>b</em><em>.</em>

A nonsecretor's genotype would be BB or Bb while a secretor's genotype would be bb.

A nonsecretor woman with a secretor father would be a carrier with genotype Bb. A nonsecretor man who in a previous marriage had a secretor daughter would also be a carrier with genotype Bb. If the two marries:

            <em>Bb     x     Bb</em>

<em>            BB    2Bb    bb</em>

1.

(a) probability of their first child will be a secretor girl = probability of having a girl and being a secretor.

Probability of having a girl = 1/2

Probability of being a secretor = 1/4

<em>probability of their first child will be a secretor girl</em> = 1/2 x 1/4 = 1/8

(b) Probability of their first child being a nonsecretor girl = probability of having a girl and being a nonsecretor.

Probability of having a girl = 1/2

Probability of being a nonsecretor = 3/4

<em>Probability of their first child being a nonsecretor girl = probability of having a girl and being a nonsecretor</em> = 1/2 x 3/4 = 3/8

2. <em>Probability that their first two children will be nonsecretors of either sex = probability of their first being a nonsecretor and of either sex and probability of their second being a nonsecretor and of either sex.</em>

  = 3/4 x 3/4 = 9/16

Think about a petal plucked from its flower. When the petal is removed from the flower, will it remain alive according to
schepotkina [342]

When a petal is plucked from a flower, it will not remain alive for very long. It will soon start to decompose.

Explanation:

To understand this, we need to go back to the act of plucking the flower as such from the plant. The moment a flower is plucked from a plant, it stops receiving any further nutrition from the plant. Whatever nutrients were present in the flower at the time of plucking it will continue to keep it alive and once those nutrients are used up, the flower will start to decompose.

In this case, since the petal is plucked from a flower which already was surviving on limited nutrients, it will decompose very quickly.

According to the characteristics of life, it cannot be considered dead at the time it's plucked. It <u>continues to live, but for a very brief time</u>.
