please what is meant by photosynthesis
Answers
Answer:
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities. Some of this chemical energy is stored in carbohydrate molecules, such as sugars and starches, which are synthesized from carbon dioxide and water, In most cases, oxygen is also released as a waste product that stores three times more chemical energy than the carbohydrates. Most plants, algae, and cyanobacteria perform photosynthesis; such organisms are called photoautotrophs. Photosynthesis is largely responsible for producing and maintaining the oxygen content of the Earth's atmosphere, and supplies most of the energy necessary for life on Earth.

Deforestation is the second leading cause of global warming (climate change) worldwide, and it produces about 24% of global greenhouse gas emissions. Deforestation in the tropical rainforests contributes more carbon dioxide to the atmosphere than the sum of all cars and trucks that drive on the world’s roads.
Why would deforestation this lead to more carbon dioxide?
a
The changed habitats support more animals, like native birds and mammals, that produce more carbon dioxide.
b
The increased amount of timber harvested produces oxygen gas, which encourages the wildlife to generate carbon dioxide.
c
Loss of trees leads to a decrease of the ability of forests to act as carbon sinks to remove carbon dioxide from the atmosphere.
d
Equipment used for clear-cutting produce metric tons of carbon dioxide, which is released into the atmosphere during the process of deforestation
Answers
Answer:
C
Explanation:
According to Worldwildlife.org, Forest play a critical role in mitigating climate change because they act as a carbon sink - soaking up carbon dioxide that otherwise be free in the atmosphere and contribute to ongoing changes in climate patterns.

Could melanin granules be moved by dynein and kinesin along an actin microfilament?.
Answers
We can confirm that melanin granules could in fact not be moved by dynein and kinesin along an actin microfilament.
Why can these substances not be moved along a microfilament?This has to do with the fact that these proteins are specific to microtubules, and therefore are not able to move along microfilaments. This is why the dynein and kinesin motor proteins would not be able to transport the granules along microfilaments.
Therefore, we can confirm that melanin granules could in fact not be moved by dynein and kinesin along an actin microfilament.

Which of the following is least involved in the mechanical breakdown of food, digestion, or absorption?.
Answers
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.
