What energy transformations are going on within the skateboarder’s body during this process?

balandron [24]

Answer:

When they slide down, they lose this potential energy, which turns into kinetic energy and thermal energy. Thermal Energy - This energy is related to the temperature of a body or a system. When friction is involved in a system, part of the kinetic energy is transformed into thermal energy.

If present, the ________________ allele will always be expressed as the phenotype.

k0ka [10]

Answer:

Dominant

Explanation:

The dominant allele will always be shown in the phenotype if it's present, because the other allele would be dominant or recessive. If both alleles are dominant, then the dominant one shows, if one of the alleles is recessive, then the dominant allele would show over the recessive one.

I think of recessive alleles as "weak" where, they just follow behind whichever other allele exists there. If the other one is dominant, then the recessive one is behind it, and no one can see it. If it other allele is recessive, a recessive allele will be in front.

During elongation in translation, to which ribosomal site does an incoming charged tRNA molecule bind?

bagirrra123 [75]

Answer:

The correct answer will be option-A site.

Explanation:

The addition of the specific amino acids to the nascent peptide occurs after the binding of the amino acid to the tRNA via acylation of the amino acid through a process called t-RNA charging.

This charged tRNA binds to the A-site or Aminoacyl site of the ribosomes where the initiation stage of the translation begins. This amino acid is shifted to the P site or peptidyl site and exit from the E site of the ribosome.

Thus, option-A site is the correct answer.

Which gland produces T3 and T4?

Leokris [45]

Answer:

1. The gland that produces T3 and T4 is the thyroid (first option).

2. True. The adrenal gland produces and allows the secretion of the hormone involved in the fight and flight response.

3.The symptom that is not correctly matched with the organ system is joint pain, which is related to the joint system, not the skeletal system.

4. False. Negative feedback loop inhibits the production and release of hormones.The symptom that is not correctly matched with the organ system is Joint pain - skeletal system

Explanation:

1. Thyroid gland is a small organ of no more than 30 grams found in the neck, in front of the trachea. This gland produces thyroglobulin, which when joined with iodine can synthesize triiodoythyronine (T3) or thyroxine (T4).

The main function of the thyroid gland is the regulation of organic metabolism, while it can also mediate the body's response to other hormones.

2. Adrenal gland is located in the upper pole of each kidney and is responsible for the secretion of several substances that help with the body's activity.

In the gland's marrow, a substance called adenaline is produced, with properties such as hormone and neurotransmitter, one of the main substances produced to deal with stress and the adaptation response called fight and flight.

The adrenaline produced in the adrenal medulla can strengthen muscles, increase heart rate and blood pressure, and increase the body's resistance to the presence of stressors or threats to physical integrity.

3. Joint pain is related to inflammation of the joint soft tissues, which belong to the joint system. Unlike joint pain, bone pain occurs as a result of injury to the periosteum -the thin membrane that covers the bones- which is related to the skeletal system.

Painful inflammation of the joints is called arthritis, and is one of the main causes of disability to perform normal body movements.

4. Feedback is a control mechanism of the endocrine system. Negative feedback loop occurs in response to a stimulus, resulting in the inhibition of mechanisms that promote the synthesis and release of substances.

An example of negative feedback is the sufficient production of thyroid hormones, which sends a signal to the hypothalamus, which in turn inhibits the production of TSH - thyroid stimulating hormone - at the level of the pituitary gland. If the pituitary does not release TSH, production of thyroid hormones ceases.
