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.

How is prey different in wet/dry seasons in Zimbabwe?
Answer:
In the dry season, the animals congregate here freely and happily. In the wet season, though,waterholes are nothing special as there are plenty of water sources throughout the parks, so the animals are more widely dispersed and the odds of seeing them along the roads and waterholes are much slimmer.

Which statement best describes the significance of meiosis to sexual reproduction?
A. It produces haploid gametes, with half the number of chromosomes.
B. It creates organisms with better adaptability to the environment.
C. It allows all types of cells to produce two sets of identical chromosomes.
D. It produces up to eight diploid cells, each with the same number of chromosomes.
In meiosis sexual reproduction produce haploid cells to produce gametes and chromosome number is reduced, hence option a is correct.
What is meiosis in sexual reproduction?Gametes or sex cells, which are needed for sexual reproduction are created during meiosis.
It deactivates the sporophytic information while activating the genetic information for the production of sex cells.
Meiosis is a kind of cell division that results in the production of four gamete cells and a 50% reduction in the number of chromosomes in the parent cell. To develop egg and sperm cells for sexual reproduction, this procedure is necessary.
Therefore in sexually reproducing organisms meiosis is important to produce gametes, hence option a is correct.

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.

After a workout, the muscles in a basketball player's legs are very sore. Which of the following statements best explains why the basketball player experiences this muscle soreness after a workout?How are the processes of photosynthesis and cellular respiration interrelated?
Answer:
1. There is an increase in the amount of lactic acid being produced in the muscle cells during the process of anaerobic respiration.
2. Photosynthesis removes carbon dioxide from the atmosphere and cellular respiration releases carbon dioxide into the atmosphere
Explanation:
Note, medical professionals consider lactic acid a byproduct released when we are engaged in intense physical exercise. Although it is still believed that the increase in the number of lactic acids causes muscle soreness, some medical findings have revealed they have no such effect on muscles.
Put simply, photosynthesis involves a natural cycle where carbon dioxide is released into the atmosphere by humans and animals for plants, and green plants undergo a process where they convert carbon dioxide into oxygen for humans. It is interrelated with cellular respiration in the sense that, cellular respiration also involves a convertion (of glucose) to carbon dioxide released into the atmosphere.

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.

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.

A. True
B. False
8. Carbon is a relatively large atom allowing it to bind to more atoms than smaller atoms would, thereby making it more versatile.
A. True
B. False
Answer:
Explanation:
Carbon is a non- metallic element with tetravalent, which means carbon posses four electrons which is available to form covalent chemical bonds. it is a chemical element with chemical symbol "C" , it has atomic number of 6, and it is categorized as a member of group 14 in the periodic table. It can form up to 4 covalent bonds, in term of electronegativity, non- metal like Oxygen and nitrogen have a stronger electronegativity compared to carbon which means there is a strong pull on a shared electron. The carbon backbone of a molecule is made up of a string of carbon atoms held together with either single or double bonds.

8. Carbon is a relatively large atom allowing it to bind to more atoms than smaller atoms would, thereby making it more versatile.
B. False
It is true that carbon atom can form up to four covalent bonds. It is false that carbon atom has six electrons in its outermost shell. It is also false that the bond between a carbon and hydrogen atom is a polar bond. The answers are A. True, B. False, B. False, A. True, B. False, A. True, A. True, and A. True.
Up to four covalent connections can be formed by a carbon atom. The reason for this is that carbon possesses four valence electrons, which enable it to share electrons with other atoms to complete its octet and create durable covalent bonds.
The outermost shell of a carbon atom only contains four electrons, not six. With a total of six electrons—two in its inner shell and four in its outer shell—carbon has an atomic number of six.
A nonpolar, not a polar, bond forms between an atom of carbon and an atom of hydrogen. Due to their identical electronegativities, carbon and hydrogen share the same number of electrons, resulting in a nonpolar covalent connection.
Compared to carbon, oxygen and nitrogen have larger electronegativities, which means that they exert more of a pull on the shared electrons in chemical bonds.
Under normal circumstances, bonds between carbon and other atoms are typically stable and do not easily dissolve.
A chain of carbon atoms bound together by single or double bonds makes up the carbon backbone of a molecule.
A molecule's carbon backbone can take on a variety of forms, such as straight, ring-like, or extremely branched ones.
Compared to lesser atoms, carbon is a comparatively big atom, which enables it to make numerous bonds and attach to more atoms.
Carbon's adaptability is a significant property that contributes to the complexity and diversity of organic compounds.

Explanation:
Krusty was told that a certain itching powder was the newest best thing on the market; it even claims to cause 50 % longer lasting itches. Interested in this product, he buys the itching powder and compares it to his usual produce. One test subject (A) is sprinkled with the original itching powder, and another test subject (B) is sprinkled with the Experimental itching power. Subject A reported having itches for 30 minutes, Subject B reported to have itches for 10 hours.
Hi, you've asked an incomplete question. The full question reads;
1. Identify the:
Control GroupIndependent VariableDependent Variable2. Explain whether the data supports the advertisement's claims about its product.
Answer:
Subject AThe "certain itch powder"The time of itchinessExplanation:
1. Remember, the Control group in research often refers to the group in a research experiment that who are not subjected to any treatment, rather they are used as a comparison scale to see how other tested subjects perform.
We also need to note here that the independent variable here refers to a variable or factor that does not change (ie it is independent), but which results in changes in other variables. From the study, the "certain itch powder.""The time of itchiness" is a dependent variable because it does change, or can be affected by the independent variable.2. Remember, the advertisement of the "certain itching" "claims to cause 50% longer lasting itches". Hence, we can conclude that the data support the advertisement claims since subject B did itch over 50% longer than subject A. In fact, we are subject B itched for 10 hours, not the 30 minutes subjet A itched.
