White spotting, or piebald trait, characterized by an absence of hair pigment in specific places, is caused by mutant copies of a A) carbohydrate. B) gene. C) lipid. D) steroid

Answers

Answer 1

Answer:

Answer: Gene

Explanation:

Mutation can be defined as the change in the single base pair of the DNA. Each and every trait inside an eukaryotic organism body is controlled by the help of the gene.

Pie bald is also a trait controlled by the genes in the body. Pie bald can be defined as a pattern of unpigmented spots on the pigmented background of scale, feather and hair.

Example: A pie bald black and white dog is a black dog with white spots on it.

Answer 2

Answer: B. Gene. Piebalding is caused by mutant copies of genes.

1. Which macromolecules were present in the unknown solution? In the milk?

Answers

These macromolecules could either be amino acids, proteins or nucleic acids. They are responsible for the chemical changes and reactions that affects largely the cell and its composition. Take for instance the cytoplasm of the cell where these organelles are settled. These simple organelles are composed of macromolecules which ignites and catalyses different functions that enables cells, in macro-perspective in motion and metabolism. In intestines for example, metabolism happens and breaking down parts of a food to simpler compounds that are used and these nutrients delivered throughout the body and again broken down by into smaller components.

A fruit jam processing unit uses a food-processing method that deactivates the enzymes in the kiwis used to make jam while retaining the bright color of the fruit. Which food processing method does it use?A. steaming B. freezing C. magnetic cooling D. blanching

Answers

Answer:

D. blanching

Explanation:

Bleaching is a short application thermal process with pre-treatment characteristics, as it precedes the start of other industrial processes. This operation performs the following actions:

Produces inactivation of enzymes that affect product quality during and after processing. Peroxidase and catalase are the most heat resistant enzymes, serving as indicators of good bleaching.

Helps clean food by reducing the amount of microorganisms on its surface.

It softens and swells the plant tissues, so as to give more uniform mass to the food within the given container.

Softens the skin of vegetables that will be peeled.

It unleashes the gases contained in the plant tissues, reducing the corrosion of the cans and facilitating the vacuum in the free space.

It favors the fixation of the coloration of certain vegetable pigments.

It leads to the loss of heat-sensitive vitamins and water-soluble nutrients. When in excess, it damages the texture.

Blanching is the food processing method that deactivates the enzymes in the kiwifruit used to make jelly while maintaining the bright color of the fruit.

The correct answer would be D.blanching.

9. The action of insulin on sugar levels in the blood helps to interfere with homeostasis (2) maintain dynamic equilibrium (3) coordinate enzyme production (4) regulate digestion of protein

Answers

Insulin's action on blood sugar levels helps maintain a dynamic balance. Therefore, the correct option is B.

The pancreas secretes the hormone insulin, which is essential for controlling blood sugar levels. Insulin is released into the bloodstream when blood sugar levels rise, as they do after a meal. Insulin aids in the maintenance of dynamic equilibrium by encouraging the uptake of glucose from the blood into cells, where it can be used as an energy source or stored for later use.

Therefore, the correct option is B.

How does targeted cancer therapies differ from traditional chemotherapies

Answers

Chemotherapy tends to kill all cells, including healthy ones, in order to eradicate malignant cancer. Targeted cancer therapies aim to solely eradicate the cancerous cells in the affected region.

Answer:

Chemotherapy drugs destroy cells that grow and divide rapidly. However, in addition to the cancer cells that replicate rapidly, they also kill normal, healthy body cells in the hair and skin causing significant side effects. Targeted therapies are an advancement in medicinal chemistry because they specifically target cancer cells, which will reduce damage to healthy cells. Also, some targeted therapies may be less toxic on the body overall, even though side effects still occur.

Explanation:

The fight-or-flight response in humans is activated by epinephrine, a hormone secreted by the _____ glands.pituitary
thyroid
parathyroid
adrenal

Answers

The correct answer is adrenal

Adrenal glands are also called suprarenal glands which are located on the kidneys. They produce various hormones including epinephrine (adrenaline). Adrenaline is secreted when a person is under a fight-or-flight. This hormone quickly responds to the emergent situation or threat by increasing heart rate, slowing blood flow to muscle cells and changes other autonomic nervous functions, which gives energy and strength to fight any emergency.

The sympathetic nervous system. The hypothalamus, in close association with the limbic system of the brain. The two main chemicals invoved here are the neurotransmitter "norepinephrine" (noradrenaline) and the hormone "epinephrine" (adrenaline).
