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.

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.

How might the digestive system and the immune system interact to help protect the body?
Please i need a correct and accurate answer. ++ giving brainliest
Answer:
Around 70% of our immune system dwells in our digestive tract in the form of gut-associated lymphoid tissue (GALT). An important component of our immune system called plasma cells (which give rise to invader-defending antibodies) also reside within the GALT. Our gut is the major channel between the external environment and the internal systems of our body. It is exposed to plenty of germs and harmful invaders such as bacteria and viruses present in food particles on a daily basis. [1] These toxic agents are perceived by the immune system in the gut as being harmful to our body and attacked. That being said, our body does not reject everything we put into it. This process is known as tolerance. When our immune system rejects an otherwise harmless substance, we are labeled as being sensitive or allergic to that food/food ingredient.

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.

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

Explain why photosynthesis is vital for life.
Answer:
Photosynthesis is important to living organisms because it is the number one source of oxygen in the atmosphere. Without photosynthesis, the carbon cycle could not occur, oxygen-requiring life would not survive and plants would die.
Explanation:
Answer:
Photosynthesis is vital for plant life, because it provides plants with a means to produce energy. Photosynthesis indirectly provides organisms that feed on plants with energy as well. Organisms that feed on plants derive their energy from the plants, which obtained their energy from sunlight through the process of photosynthesis. Photosynthesis also helps maintain atmospheric levels of carbon dioxide and oxygen. Carbon dioxide is taken in by plants during photosynthesis, and oxygen is released.
