Can someone please help me? :(
Answer:
B i think or C
Explanation:
Because in the way I am thinking it's B, "School cooks should be educated on allergies to peanuts." It makes the most sense
Answer: b
Explanation:
it can't be a since source 2 says "few people recognize..." which contradicts "students know what to do..."
it can't be c because there is no source comparing peanut allergies now vs. past.
it can't be d because you cannot infer this from the given data.
leaving us with b because since a majority of peanut allergies happen at school and not many know how to deal with an event with a peanut allergy, then teaching cooks about peanut allergies will help students in the case of an allergic reaction in school.
hope this helped! ♡
Which of the following is least involved in the mechanical breakdown of food, digestion, or absorption?.
Answer:
Esophagus
Explanation:
In the digestion and absorption of food, the esophagus is the least involved.
It is a part of the digestive system, but all it does is simply pass the food down to the stomach.
The one that is least involved in the mechanical breakdown of food, digestion, or absorption is esophagus. The correct option is d.
Even though it is a vital component of the digestive system, the esophagus plays a much smaller role in the mechanical digestion of food than the other alternatives.
A muscular tube called the esophagus moves food from the mouth to the stomach by a process known as peristalsis, which calls for repetitive muscle contractions.
Its main job is to push food down the digestive tract so that it can travel more easily. Food is mostly mechanically broken down in the mouth while being chewed by the teeth and in the stomach while being churned by muscles.
The majority of digestion and nutrient absorption occurs in the small intestine.
Thus, the correct option is d.

What is the role of cells in vision?Two types of specialized cells are found in the eye for vision. These are named as rods and cones. These cells are called as photoreceptors as they are sensitive to light and thus functions in response to light.
Rod cells function in response to dim light and thus are active during the night time whereas cone cells impart colour vision.
These photoreceptor cells detect the light and convert them into electrical signals. Such electric signals travel to the brain from the retina through optic nerve. Brain thus helps in the perception of objects.
Defects in the rod cells leads to night blindness. It is also due to the deficiency for vitamin A which is pre-requisite for the activation of rod cells. Colour blindness (inability to distinguish between primary colours) can result if the cone cells are damaged.
Thus, photoreceptors cells are important in vision and image formation.

Which of the following best describes the part of the blood composition that forms clots around wounds to prevent blood loss? Plasma Platelets White blood cells Red blood cells
Answer:
Platelets
Explanation:
Platelets are small pieces of dead blood calls that clump together to form a netting also known as a scab. These scabs stop bleeding, preventing every wound from being fatal and allowing the body time to heal.
Small fragments of dead blood cells called platelets collect together to form a netting, also known as a scab. Because these scabs stop the bleeding, no cut becomes fatal, and the body has time to heal. Thus, option B is correct.
What role of Platelets in clots around wounds?Blood clotting is the main function of platelets, also known as thrombocytes. Compared to other blood cells, platelets are significantly smaller.
In order to stop bleeding, they congregate to create clumps or plugs in the hole of a vessel.After the wound has healed, your body will often spontaneously dissolve the blood clot.
Therefore, As soon as the vessel's margins are broken, platelets start to stick to them and release chemicals that draw in additional platelets. External bleeding stops as soon as a platelet plug forms.

How can we stop carbon dioxide to the ocean to not affect pH levels?
Answer:
Because of human-driven increased levels of carbon dioxide in the atmosphere, there is more CO2 dissolving into the ocean. The ocean's average pH is now around 8.1 , which is basic (or alkaline), but as the ocean continues to absorb more CO2, the pH decreases and the ocean becomes more acidic.
Hope This Helps
Answer:
Carbon dioxide (chemical formula CO2) is a chemical compound occurring as an acidic colorless gas with a density about 53% higher than that of dry air. Carbon dioxide molecules consist of a carbon atom covalently double bonded to two oxygen atoms. It occurs naturally in Earth's atmosphere as a trace gas. The current concentration is about 0.04% (412 ppm) by volume, having risen from pre-industrial levels of 280 ppm.[9][10] Natural sources include volcanoes, forest fires, hot springs, and geysers, and it is freed from carbonate rocks by dissolution in water and acids. Because carbon dioxide is soluble in water, it occurs naturally in groundwater, rivers and lakes, ice caps, glaciers, and seawater. It is present in deposits of petroleum and natural gas. Carbon dioxide has a sharp and acidic odor and generates the taste of soda water in the mouth,[11] but at normally encountered concentrations it is odorless.[1]
