What type of inheritance controls blood types in humans?
Answer:
Human blood types (ABO) are an example of multiple alleles. Polygenic inheritance occurs when more than one gene controls the trait.
Explanation:
put it in your own words
Human blood types (ABO) is the inheritance that controls blood types in humans. Polygenic inheritance occurs when more than one gene controls the trait.
What is polygenic inheritance?A polygene is a member of a group of non-epistatic genes that interact additively to influence a phenotypic trait, thus contributing to multiple-gene inheritance, a type of non-Mendelian inheritance, as opposed to single-gene inheritance, which is the core notion of Mendelian inheritance.
Moreover, polygenic inheritance refers to the inheritance of a trait governed by more than one genes. Generally, three or more genes govern the inheritance of polygenic traits. Multiple independent genes have an additive or similar effect on a single quantitative trait.
Therefore, polygenic traits are determined by the interactions between several different genes, which display incomplete dominance.

B. Dermatomes are involved in referred visceral pain.
C. If a person experiences damage or infection in an internal organ, the pain may be experienced elsewhere due to dermatomes.
D. Dermatomes are important in discovering muscle or organ damage, but are not useful in identifying spinal nerve damage.
Answer:
A. Pain in a dermatome can only arise from the region of the skin that is innervated by that spinal nerve.
D. Dermatomes are important in discovering muscle or organ damage but are not useful in identifying spinal nerve damage.
C. If a person experiences damage or infection in an internal organ, the pain may be experienced elsewhere due to dermatomes.
Explanation:
A dermatome is a region on the skin innervated by a spinal cord's root or dorsal nerve. The cutaneous nerves are those that reach the skin, collecting the sensitivity of it. Each cutaneous nerve is distributed in a particular area of skin, called a dermatome. From each segment of the medulla arises a pair of posterior roots sensory and a pair of anterior or motor roots, which join laterally to the intervertebral foramen level to form a mixed spinal nerve. Each of these innervates a dermatome strip of skin, so the surface corporal can be considered a true mosaic.
This term has three meanings:
Skin neoplasms (tumors)A strip of skin territory innervated by sensory fibers originates from a posterior root (nerves originating in the spinal cord and exiting between two vertebrae), also called the spinal nerve.For its part, the dermatome razor is a kind of razor that allows you to take cutaneous fragments, more or less thick, to perform skin grafts.A dermatome region posses the following characteristics traits as shown in option A, D, and C

List two things that might happen if the snake was removed from this food chain.
What would be the result of removing the decomposers from the food chain?
Explanation:
1. The population of the pray that snakes feed on would grow
2. The predators that feed on snakes may die out
if the snake was removed from this food chain, the population of the prey that snakes feed on would grow and the predators that feed on snakes may die out. Remains of other organisms build up in an ecosystem if the decomposers are absent.
How each organism is important for the food chain?Each creature in the food chain depends on an earlier link in the chain. When a creature is eliminated from the food chain, the ecosystem's energy and nutrient cycles are disrupted.
The stability of the food chain is upset. As a result, the species that rely on other organisms for nourishment will starve to death.
The remains of other organisms build up in an ecosystem if the decomposers are absent.
Therefore, the ecosystem becomes unbalanced because the nutrients are not returned to the source to be used by the producers.

Which of the following phrases describe the function of the digestive system?
l. Smooth, muscular tube connects the mouth to the stomach
ll. Muscular action in the esophagus pushed food to the stomach
lll. Structures called the microvilli to increase the surface area of the intestines
lV. Nutrients are made available to the body's cells
A. l and ll
B. ll and lll
C. ll and lV
D. lll and lV
Answer:
B. ll and lll
Explanation:
The question above is asking for the "function" of the Digestive System. Function refers to how the digestive system actually works.
I is not related to the function of the digestive system. It only describes the "esophagus."
II is called the "Peristalsis." This is one of the functions of the digestive system. This allows the food to move down the GI tract.
III is part of the process called "Segmentation." This is one of the functions of the digestive system. The increase surface area of the microvilli expands 25 times and this allows greater absorption of food.
IV is not related to the function of the digestive system.

A hand sanitizer was advertised to be more effective at killing bacteria than any antibacterial soap. Students were split evenly into 4 groups to test this claim. Groups 1-3 washed their hands using the assigned hand sanitizer or soap (see table) and warm water for two minutes, and then dried their hands with a paper towel. Group 4 rubbed their hands vigorously for 2 minutes in warm water, without any soap or sanitizer, and then dried their hands with a paper towel. After washing, each student’s hands were swabbed and the swab was applied to a culture plate and incubated. Finally, the bacterial cultures were counted. what is the independent variable?
Answer:
Group 4
Explanation:
The control group in this case would be those students in group 4.
The control group during an experiment is a group that does not receive the treatment administered to other groups and as such used as a standard for measuring the effects of the treatment on other groups. Whatever differences that exist between the control group and the various treatment groups is attributed to be as a result of the treatment administered to the groups.
In this case, group 4 only used warm water for washing their hands instead of the hand sanitizer/soap used by the other groups. Whatever differences found out in the bacterial count in their respective culture swabs can be attributed to the effects of the hand sanitizer/soap.
