Explanation:
The lysosomes are the cellular organelles containing the hydrolytic enzymes which help in the metabolism of the complex and toxic compounds. The alcohol which is consumed is degraded and digested by the lysosomes which decrease the rate of digestion of the other complexes like the proteins. This decreased lysosomal activity leads to liver damage.

. As the volume of the cell increases, how does the surface area to volume ratio (SA/Ve) change?
Answers
Answer: Well, you see, As the cube size increases or the cell gets bigger, then the surface area to volume ratio - SA:V ratio decreases. ... When a cell grows, its volume increases at a greater rate than its surface area, therefore it's SA: V ratio decreases.

What is the internal and external adaptation in a leaf for photosynthesis? Please give a clear short answer (prefer in bullet points). I will give brainliest to fastest answer
Answers
Answer:
They are adapted for photosynthesis by having a large surface area, and contain openings, called stomata to allow carbon dioxide into the leaf and oxygen out. ... The cells inside the leaf have water on their surface. Some of this water evaporates, and the water vapour can then escape from inside the leaf.
Answer:
▪︎leaf with large surface area
▪︎dark coloured leaf for maximum sunlight absorbtion
▪︎has stomata openings to allow carbon dioxide diffuse in the leaf
▪︎It has the green pigment :chloroplast inside to absorb sunlight
Is DNP and cyanide an inhibitor of cellular respiration?
Answers
Answer: Yes.
Explanation:
DNP and cyanide are both cellular respiration inhibitor.
Cyanide is a neurotoxin that can prevent cellular respiration by it's inactivation activity on mitochondria enzymes called cytochrome oxidase.
DNP (2,4-Dinitrophenol is a chemical that inhibit cellular respiration. It help to shuttle proton across cell membranes of living cells by spreading the proton along along the mitochondria and collapsing the force that produced energy for the cell activities.

in summer, what happens to the hurricane’s temperature, category, and speed as it travels across a body of water and then land?
Answers
I think it starts to get slower as soon as it starts traveling because then hurricanes wouldnt be as bad and would be long, and it could possible get worse as it travels across the water because it could be sucking up water so then it would get bigger and worse. The tempertaure will get colder because it will then start to pour and cause destruction and make it windy and very chilly.
In summer the temperature of hurricane will get colder because it will then start to pour and cause destruction and make it windy and very chilly and it could be sucking up water so then it would get bigger and worse.
What is hurricane?Hurricane has been defined as the conditions which has been expected in a specified area. As defined by National Oceanic and Atmospheric Administration (NOAA), it means that hurricane conditions (sustained winds of 74 mph or greater) are possible within your area and hurricane warnings means hurricane conditions are expected in an area.
The warm ocean water allows more water to get evaporate and this gives more power for the Hurricane to began. Powerful winds clash as a result of the air to move towards upwards which has light wind around the area allows it to start moving round and round with this whole process continues to make the Hurricane powerful and faster.
Therefore, In summer the temperature of hurricane will get colder because it will then start to pour and cause destruction and make it windy and very chilly and it could be sucking up water so then it would get bigger and worse.

Answers
Answer:
The correct answer is-
4. true
5. Natural selection
6. microevolution
Explanation:
Adaptive radiation is a cycle where living beings diversifying rapidly from a familial or an ancestral species into a huge number of several new types, especially when there are new environmental aspects present such as different habitats and few competitors.
Thus, it is a true statement.
Natural selection is the cycle through which a population or a species of living beings adjust and change over the period of time. natural selection just acts upon the heritable attributes of a population by choosing for advantageous alleles or and in this manner increasing the frequency of these adaptive alleles in the population.
Thus the option Natural selection is correct.
Changes inside a genetic pool from happening to one generation to another is known as microevolution. Allele frequencies in a population may change because of, natural selection, mutation, genetic drift, and genetic flow.
Thus, the correct answer is - microevolution.
