If a cell has 32 pairs of chromosomes in its diploid state, how many chromosomes will it have after Meiosis 1? A. 8 B. 64 C. 32

Lostsunrise [7]

Answer:

option c is correct that is 32

Explanation:

meiosis occur in two phases in the first phase DNA replication occur and amount of DNA becomes doubled without any changes in the chromosomes number and two daughter cells( each 2n) are formed

now in stage 2 each daughter cell undergoes mitosis with the formation of two cells each with half chromosomes (n)

now 2n =32

n=32/2=16

after meiosis stage 1 ........ two daughter cell each with 32 chromosomes

stage 2.... each daughter cell form two grand daughter cell each with 16 chromosomes

What was the average of diameters (cm) for the Willapa Bay urchins sampled before the hunt? (Type just the number rounded to the

Otrada [13]

Answer:

See Explanation

Explanation:

The question is incomplete as the diameters of the Willapa Bay urchins were not given.

However, I'll give a general way to solve this problem.

Average is calculated using:

$Average = \frac{\sum x}{n}$

i.e. Sum of all diameters divided by the number of bay urchins.

The diameter of urchins is usually between 6cm to 12cm; So, I will assume the following diameters for 10 urchins.

10cm, 8cm, 10cm, 7cm, 9cm, 10cm, 6cm, 10cm,8cm, 8cm

Using the above data, the average is:

$Average= \frac{10+8+10+7+9+10+6+10+8+8}{10}$

$Average= \frac{86}{10}$

$Average= 8.6$

The human body is able to synthesize them: proteins, fats

Contains nitrogen in the amine group : proteins

Made according to instructions from DNA: proteins

Explanation:

The cells of the human body synthesize proteins from the transcription and translation processes.

Fats and carbohidrates are ingested in the diet and metabolized by the body. However some types of fat such as cholesterol is synthesized by the human body. Same as phospholipids that are part of the membranes.

Proteins are formed by hydrogen, oxygen, nitrogen and carbon. Amino acids are characterized for owning a carboxyl group (- COOH) and an amino group (-NH2)

Explanation: Lymphatic tissues have various distinct configurational groups correlated to its specific purpose in the resistance of a particular infection reaction. Lymphatic tissues can be primary or secondary in basic features, the primary lymphatic tissues in humans being thymus and bone marrow. However, the lymphocytes are shaped from a long thin corroborative section of cells in the soft fatty material in the compartments of bones in which cells are generated and then distributed in the lymphatic tissue.
