Answer: Cellular respiration

Explanation:

In the presence of oxygen glucose is oxidised through a series of enzyme coordinated reactions to produce energy which is stored in form of ATP.

Metabolism is the process that is responsible for an increase in chemical energy for cell activities in organisms living on the earth possible.

<u>Explanation</u>:

Metabolism is the set of the chemical reactions that occurs in the living cells. All the living organisms needs some energy for growth and reproduction. Metabolism is the process that continues the chemical process in the organisms and activates the organisms to convert the chemical energy that stored in the molecules into other form of energy which can be used for the cellular process.

Nonamiya [84]

The provided question is incomplete as it lacks the image required to identify the, however the correct image is attached:

Answer:

B is protein

C is the process of translation

Explanation:

The given image is a flow chart representation of the process of the protein synthesis from the DNA molecule by a two-step process that is combinedly known as the central dogma.

The first step is a transcription in which an RNA molecule (mRNA) is synthesized from the DNA molecule in organism nucleus (in eukaryotes only). The second step is to making a polypeptide chain of amino acid with help of rRNA, tRNA, and mRNA, this process is known as translation and represented in the image as C and B is the protein that formed.

Thus, the correct answer is - B is protein

C is the process of translation

Organisms with the genotypes aabbccdd and aabbccdd are crossed. What are the expected proportions of the following progeny?

Dvinal [7]

Answer:

a) $\frac{27}{64}$

b) $\frac{1}{32}$

c) $\frac{27}{64}$

d) $\frac{3}{64}$

Explanation:

The correct question is

Organisms with the genotypes AABbCcDd and AaBbCcDd are crossed. What are the expected proportions of the following progeny?

a. A_B_C_D_

b. AabbCcDd

c. a phenotype identical to either parent

d. A_B_ccdd

Solution

In such question the probability for each allele pair is to be determines separately

For instance,

AA * Aa will produce AA, Aa, AA, Aa this means that all the the probability of getting both AA and Aa is $\frac{1}{2}$

Like wise when Bb and Bb are crossed, BB, Bb, Bb, and bb are produced. So the probability of getting dominant trait i.e BB or Bb is $\frac{3}{4}$ and recessive trait i.e bb is $\frac{1}{4}$

Chance to get homozygous bb only or BB only is $\frac{1}{4}$

and chance of getting Bb is $\frac{1}{2}$

Like Bb and Bb cross, the same will be the probabilities for Cc and Cc cross and Dd and Dd cross

Part A)

$\frac{1}{4} * \frac{3}{4} * \frac{3}{4} * \frac{3}{4} \\= \frac{27}{64}$

Part B)

$\frac{1}{4} * \frac{1}{2} * \frac{1}{2}* \frac{1}{2}\\= \frac{1}{32}$

Part C)

$\frac{1}{4} * \frac{3}{4} * \frac{3}{4} * \frac{3}{4} \\= \frac{27}{64}$

Part D)

$\frac{3}{4} * \frac{1}{4} * \frac{1}{4} * \frac{1}{4} \\= \frac{3}{64}$

aleksandrvk [35]

Answer:

Clostridium tetani

Explanation:

Clostridium tetani causes tetanus, a disease that classically follows injury to the body. Clostridium tetani spores, which are commonly in soil and animal faeces are deposited in the wound and germinate in anaerobic condition. It releases toxins which are tetanospasmin and tetanolysin. Tetanospasmin is responsible for sustained contraction while tetanolysin is responsible for hemolysis of blood cells which is commonly associated with clostridium tetani.
