Sometimes the reflex response is diminished or absent- a phenomenon termed hyporeflexia. Do you think hyporeflexia would be caused by disorders of the central nervous system or the peripheral nervous system? Explain your reasoning.

Answers

Answer 1

Answer:

Answer:

The functions of the skeletal muscles are affected by the CNS via the two sets of neurons, that is, lower motor neuron and upper motor neurons. The PNS comprises sensory neurons and motor neurons. The lower motor neuron is monitored by the upper motor neuron.

Hyporeflexia occurs because of the dysfunction of the lower motor neuron or its lesion. The lower motor neurons refer to the neurons, which innervate the skeletal muscles directly. Destruction to the central nervous system leads to hyper reflexes and destruction to the peripheral nervous system results in hyporeflexia.

A)
Meiosis produces genetically diverse cells.
B)
Meiosis increases genetic variation in the offspring.
C)
Meiosis produces haploid cells from a diploid parent cell
D)
Meiosis increases the genetic content in the daughter cells.
E)
Meiosis maintains the number of chromosomes originally present in the
parent cell.

Answers

Final answer:

The accurate statements are: Meiosis produces genetically diverse cells, Meiosis increases genetic variation in the offspring, and Meiosis produces haploid cells from diploid parent cell. The inaccurate statements are: Meiosis increases genetic content in daughter cells, and Meiosis maintains original number of chromosomes in parent cell.

Explanation:

The following statements accurately describe the outcome of meiosis:

Meiosis produces genetically diverse cells. This is true. During meiosis, the genetic material from two parent cells is combined in unique ways, resulting in genetically diverse offspring.
Meiosis increases genetic variation in the offspring. This statement is also true due to the crossing over and independent assortment processes during meiosis I, which create new combinations of genes in the gametes.
Meiosis produces haploid cells from a diploid parent cell. This is accurate. The parent cell has two sets of chromosomes (diploid), while the resulting daughter cells each have a single set (haploid) due to the reduction division in meiosis.

These statements inaccurately describe meiosis:

Meiosis increases the genetic content in the daughter cells. This is false. Meiosis actually reduces the genetic content by halving the number of chromosomes.
Meiosis maintains the number of chromosomes originally present in the parent cell. This is also false. The purpose of meiosis is to reduce the chromosome number by half in the offspring to maintain a consistent chromosome number within the species across generations.

Answer:

A) Meiosis produces genetically diverse cells.

B) Meiosis increases genetic variation in the offspring.

C) Meiosis produces haploid cells from a diploid parent cell

Explanation:

Through crossing over, meiosis produces genetically diverse cells causing more genetic variation of offspring. The Daughter cells in meiosis are formed from a diploid cell that has all 46 chromosomes, however the daughter cells are haploids as they need to join with the other gamete to have a full set of chromosomes.

In humans there is a dominant allele (A) for the absence of moles; while the recessive allele (a) results in the presence of moles. A couple who are both heterozygous for this locus (Aa) plan to have seven children. a. Expand the binomial (p + q)7.
b. What is the probability that:
(i) The first child that is born will not have moles.
(ii) All of the children will have moles.
(iii) The first two children will have no moles and the last five will have moles.
(iv) Of the 7 children, 4 will have no moles and 3 will have moles
c. Assume this couple now have two children, one with moles and one without moles. What is the probability that the child born without moles is a carrier of the a-allele (ie heterozygous)?

Answers

Answer:

a. $(p + q)^7$ = $p^7q^0+7p^6q+21p^5q^2+35p^4q^3+35p^3q^4+21p^2q^5+7pq^6+p^0q^7$

b. i. 0.75

ii. 0.000061

iii. 0.012

iv. 0.17

c. 0.67

Explanation:

a. The expansion of the binomial (p + q)7 would be such that:

$(p + q)^7$ = $p^7q^0+7p^6q+21p^5q^2+35p^4q^3+35p^3q^4+21p^2q^5+7pq^6+p^0q^7$

b. Both couples are heterozygous:

Aa x Aa

AA Aa Aa aa

Since A is dominant over a,

probability of having mole (aa) = 1/4

probability of not having moles = 3/4

Therefore, the probability of the first child not having moles = 3/4 or 0.75

ii. Let the probability of not having mole = p and the probability of having mole = q. From the binomial expansion:

$(p + q)^7$ = $p^7q^0+7p^6q+21p^5q^2+35p^4q^3+35p^3q^4+21p^2q^5+7pq^6+p^0q^7$

Probability that all of the children will have moles = $p^0q^7$

since p = 3/4 and q = 1/4

$p^0q^7$ = $(3/4)^0(1/4)^7$ = 0.000061

iii.Probability that the first two children will have no moles and the last five will have moles = $21p^2q5$

= $21(3/4)^2(1/4)^5$

= 0.012

iv. Probability that 4 will have no moles and 3 will have moles out of the 7 children = $35p^4q^3$

= $35(3/4)^4(1/4)^3$

= 0.17

c. Probability that the child born without moles is a carrier of the a-allele = probability of heterozygous.

From the cross in (b), the genotypes of those born without moles are AA and 2Aa. Therefore, the probability of not having moles and be Aa is:

= 2/3 or 0.67

Translate this sequence from mRNA to protein: AUG CAC UCG

Answers

Answer:

The result of the translation of the mRNA sequence AUG CAC UCG into protein is methionine, histidine and serine.

Explanation:

Messenger RNA (mRNA) is responsible for carrying the sequence of nitrogenous bases of its molecule to the ribosome to be translated into amino acids and synthesize proteins.

Three nucleotides of mRNA form triplets or codons that can encode:

The initiation of protein synthesis, with the AUG codon also coding for methionine.
Amino acids to be added to the peptide chain.
Stopping protein synthesis.

For the mRNA base sequence AUG CAC UCG, the amino acid sequence that corresponds to the synthesized peptide or protein is Met-His-Ser, i.e. methionine, histidine and serine.

What is the process by which substances in food are transformed into body tissues and provide energy for the full range of physical and mental activities that make up human life?

Answers

The absorbed food materials are transported by blood and lymph. Lymph is finally transferred to the blood circulation. The blood transports absorbed food materials to different body cells where food materials become integral component of the living protoplasm and are used for energy, growth and repair. This is called assimilation of food.
