Answer:

Because we know that photosynthesis is a process that plants use, we can define photosynthetic protists as 'plant-like' protists that get their nutrients by converting sunlight into energy using photosynthesis.

When a tautomeric shift occurs, then the resulting mutation ALWAYS changes a purine to a purine or a pyrimidine to a pyrimidine. A tautomeric shift may lead to a point mutation.

A mutation is any alteration in the nucleotide (DNA) sequence of the genome of an individual.

A tautomeric shift can be defined as a temporary change in the nucleotide base structure.

A transition mutation is a point mutation of one purine or pyrimidine base pair to the other purine/pyrimidine that occurs when one nucleotide base undergoes a tautomeric shift during DNA replication.

Answer:

Air-sea exchange is a physio-chemical process and is important for the cycling of gases such as carbon dioxide, methane, nitrous oxide, dimethylsulfide and ammonia

A test cross performed between the individual with unkown genotype and the h0m0zyg0us recessive individual. 9) hh. 10) Hh or HH. 11) HH x hh. 12) 100% Hh. 13) Hh x  hh. 14) 50%Hh and 50% hh. 15) -16) in the text.

-----------------------------------

For this gene we will assume complete dominance, meaning that the dominant alele completely hides the expression of the recessive allele.

According to this information, we can say that

Genotype      Phenotype

HH                  Hairy pig

Hh                   Hairy pig

hh                   Hairless pig

9) Geneviene does not have hair  ⇒  Its genotype is hh

10) Fred has hair ⇒ Its genotype is HH or Hh

Possible crosses

11 and 12)

Cross1: If Fred was genotype HH and bred with Genevieve

Parentals) HH    x    hh

Gametes)   H   H    h    h

Punnett square)    H    H

                        h   Hh   Hh

                        h   Hh   Hh

F1) 100% of the progeny is expected to have hair and be heter0zyg0us, Hh.

13 and 14)

Cross2: If Fred was genotype Hh and bred with Genevieve

Parentals) Hh    x    hh

Gametes)   H   hh    h    h

Punnett square)    H    h

                        h   Hh   hh

                        h   Hh   hh

F1) 50% of the progeny is expected to have hair and be heter0zyg0us, Hh.

     50% of the progeny is expected to be hairless and be h0m0zyg0us recessive, hh.

15)  

• If the individual with the unknown genotype (Fred) is heter0zyg0us, the phenotypic rate of the descendants is 50% heter0zyg0us -Hh- and 50% h0m0zyg0us recessive -hh-.

• But if the individual with the unknown genotype is h0m0zyg0us dominant, the phenotypic rate of the descendants is 100% heter0zyg0us for the trait, Hh.  

16)

The weakness is that even if Fred is heter0zyg0us for the trait, when making the cross it might occur that all individuals in the progeny are born h0m0zyg0us recessive, and there is a risk of missinterpreting the results.

So in that situation, many crosses must be done between fred and genevieve to se sure about Freds genotype.

Answer: sympathetic nervous system

Explanation: because it is the body's rapid involuntary response to dangerous or stressful situations.

Goosebumps are a symptom of a seizure illness termed temporal lobe epilepsy, a sympathetic nervous system disorder, or other brain disorders, albeit they are uncommon. They are also common with heroin or other drug withdrawal.

The body's quick automatic reaction to hazardous or stressful circumstances is controlled by the sympathetic nervous system.A quick hormone rush raises the body's alertness and heart rate, which boosts the flow of blood to the muscles.

Therefore, In response to a threat, we perspire, breathe more quickly, get goose bumps, and feel nauseated. These responses are Sympathetic nervous system because it is the body's rapid involuntary response to dangerous or stressful situations.

Answer:

Homeostasis is the process of maintaining a constant internal environment suitable sustaining life.

Homeostasis continues to maintain ideal environment for enzyme action and all cell functions throughout the body.

It is the preservation of a constant internal environment in the face of changing internal and external conditions. These include blood glucose concentration control in the human body.

A series of control mechanisms at the organ, tissue, or cellular level maintain homeostasis.

Substrate supply, activation or inhibition of individual enzymes and receptors, enzyme synthesis and degradation, and compartmentalization are examples of control mechanisms.

The liver, pancreas, kidneys, and brain (hypothalamus, autonomic nervous system, and endocrine system) all contribute to homeostasis.

The liver is in charge of metabolizing toxic substances and maintaining carbohydrate metabolism with pancreatic signaling.

Thus, homeostasis is necessary for a cell to survive.

Because they have a wide surface area to speed up absorption, root hair cells are designed to absorb water and mineral ions.

Plants are anchored by root hairs that emerge from the surface of the soil and take up water and minerals.

Vascular tissue in the heart of the root transports food produced in the leaves to the root, while transporting water and minerals away from it.

Its main purposes include anchoring the plant, absorbing water and dissolved minerals and transferring them to the stem, as well as storing reserve food.

Water and nutrients are mostly taken up by root hairs from the rhizosphere.

Therefore, root hair cell have large surface area that enable the cell to carry out its function.
