A red flower producing snapdragon plant is crossed with a white flower producing snapgragon plant. Resulting F1 generation is crossed with one another to produce F2 generation.
This is incomplete dominance of genes.
Q1 What type of a breeding is this? (monohybrid, dihybrid or interspecific)
Q2 Draw a genetic chart to show P, F1 and F2 generations clearly indicating genotypes, phenotypes and generations.
Answers
Answer:
See the answer below
Explanation:
1. This is an example of monohybrid breeding. A monohybrid breeding is the type of breeding that involves parents with a pair of contrasting characters. On the other hand, a type of breeding involving a single gene is what is known as monohybrid breeding.
2. When a red flower snapdragon is crossed with a white flower snapdragon, the resulting offspring are usually pink - an indication of incomplete dominance of the gene responsible for flower color. Assuming the red flower's genotype is AA and that of the white flower is aa:
AA x aa
Aa Aa Aa Aa
F1 genotype = all Aa
F1 phenotype = pink flower
At F2:
Aa x Aa
AA 2Aa aa
F2 Genotype/phenotype:
1AA - red color
2Aa - pink flower color
1 aa - white flower color.

A. There will be no difference as compared to an area that has saprotrophs and detritivores. •
B. There would be nothing left, it will have completely decomposed. •
C. The body would remain, and be just as it was when it died except for weathering. •
D. The body would be decomposing at about half the normal speed.
The correct option is C.
The body would remain, and be just as it was when it died except for weathering.
Explanation:
"If an organism were to die in an environment that had no saprotrophs or detritivores, The body would remain, and be just as it was when it died except for weathering because detrivores and feed on organic matter and excrete the nutrients, without detrivores and saprotroph the the organic matter in the dead organisms will still remain the same.
Detrivores are organisms that feed on dead organic matter and releasing nutrients to the ecosystem through it's wastes.
Saprotroph are decomposers that survive on or in dead organic matter secreting enzymes and releasing nutrients to the ecosystem. Examples is fungi.
Without detrivore and and saprotroph the dead organisms will remain the same except from weathering be side weathering is carried out through the activities of air, water or some agents.

The client has experienced a stroke, and her speech is now garbled. The client may have experienced damage to which of the following?
A. Brainstem
B. Medulla oblongata
C. Frontal lobe
D. Cerebellum
Answers
Answer:
C
Explanation:
A person with garbled speech may have experienced damage to the frontal lobe portion of the brain.
This is because the left portion of the frontal lobe of the brain is an area that has been touted to be responsible for the control of speech in humans. Research in the past has shown that damage to that region of the brain affects the formation of spontaneous speech as well as motor speech control.
Hence, garbled speech in someone that has experienced stroke can be attributed to damage to the frontal lobe.
Correct option: C.

Which hormone released by the highlighted structure stimulates the release of TSH from the anterior pituitary (adenohypophysis)? Which hormone released by the highlighted structure stimulates the release of TSH from the anterior pituitary (adenohypophysis)? TRH CRH GHIH GHRH
Answers
Answer:
Explanation:
hypothalamus release thyrotropin releasing hormone(TRH) which stimulate the pituitary gland to release TSH
The activity of the thyroid gland is regulated by thyroid-stimulating hormone (TSH), also called thyrotropin. TSH is released from the anterior pituitary in response to thyrotropin-releasing hormone (TRH) from the hypothalamus.
How do you stimulate TSH production?Eating a portion of Essential Fats at every meal which includes extra olive oil, flaxseed oil, raw unsalted nuts and seeds, avocados, and oily fish, will improve thyroid hormone levels as our cell receptors become more able to take up thyroid hormone.

If the gametes from a diploid individual only contain one of the two possible alleles, it is not difficult to determine the genotypes of the gametes from that individual. For the diploid genotypes indicated below, write all of the possible genotypes of the gametes. If more than one type of gamete is possible, separate them with a comma. Diploid Genotype Genotype of Gametes RR rr Rr
Answers
Answer:
Diploid Genotype - Genotype of Gametes
RR - R
rr - r
Rr - R, r
Explanation:
According to Gregor Mendel in his law of Segregation, he stated that the alleles of a gene gets separated into gametes during gamete formation (meiosis). This occurs in such a way that only one allele of the two possible alleles that make up the genotype of a diploid organism is found in the gamete.
Meiosis is a cell division that reduces the chromosomal number of the daughter cells. Hence, a diploid organism (2n) will undergo meiosis to produce haploid (n) daughter cells (gametes). An organism with a diploid genotype RR will produce gametes which have only genotype R. The same applies to organism with genotype rr. Only gametes with genotype, r, will be produced.
However, in a heterozygous genotype like Rr, the different alleles will separate into gametes in an equal proportion i.e. gametes with genotypes R and r will be produced in a ratio 1:1.

Explanation:
Answer:
The phagocytes cell in the skin are the monocytes, macrophages, neutrophils, tissue dendritic cells and mast cells. One litre of human blood contains about six billion phagocytes.
When pathogens are detected, the immune system produces millions of white blood cells, which fight the infection. Blood vessels near the wound expand, and white blood cells move from the vessels to enter the infected tissues. Many of these white blood cells are phagocytes which engulf and destroy bacteria.

How does your body know when cells are missing
Answers
Answer:
Receptors provide information to nervous system about missing cells.
Explanation:
Your body know when cells are missing due to nervous system. The network of nervous system spreads throughout human body which provide information about what is going on in the body. If the cells are missing due to injury, the nervous system gives instruction to the body to produce more cells and transported that cells to the region where these cell are required. So receptors are responsible to provide information to nervous system about missing cells.
The body knows cells are missing as a result of the receptors sending
to the central nervous system.
The human body consists of cells which have neurons. These neurons are
responsible for the passage of messages and information to other parts of
the body.
When a cell is missing from the body, signals are passed to the central
nervous system which consists of the brain and spinal cord and they then
relay impulses which helps to fix the issue so as to ensure optimal
functioning of the body.

Myristoyl-CoA is a saturated fatty acid with 14 carbons attached to coenzyme A. How many molecules of ATP would be generated from the complete oxidation of a single molecule of myristoyl-CoA
Answers
Answer:
Total ATP molecules produced = 94 molecules of ATP
Explanation:
Myristoyl-CoA, is a saturated fatty acid with 14 carbons which has been activated for oxidation by attachment to coenzyme A. When it has undergone complete oxidation, it will yield 7 acetyl-CoA molecules and 6 FADH₂ and 6 NADH molecules each.
Each of the 7 acetyl-CoA molecules obtained from its initial oxidation enters into the citric acid cycle and is completely oxidized to yield further ATP and FADH₂ and NADH molecules.
The overall yield of ATP from the various enzymatic steps is shown below:
Acyl-CoA dehydrodenase = 6 FADH₂
β-Hydroxyacyl-CoA dehydrogenase = 6 NADH
Isocitrate dehydrogenase = 7 NADH
α-Ketoglutarate dehydrogenase = 7 NADH
Succinyl-CoA synthase = 7 ATP (from substrate-level phosphorylation)
Succinate dehydrogenase = 7 FADH₂
Malate dehydrogenase = 7 NADH
Note: 1 FADH2 molecule yields 1.5 ATP; 1 NADH molecule yields 2.5 ATP molecules. Therefore,
Total ATP from FADH₂ molecules = 13 * 1.5 = 19.5
Total NADH molecules = 27 * 2.5 = 67.5
Total ATP molecules produced = 19.5 + 67.5 + 7 = 94
Total ATP molecules produced = 94 molecules of ATP
