On average, women tend to carry extra weight around their bellies. Thus, option "B" is correct.

An excess in fat will cause it deposited in various parts of the body. One of the locations is the visceral part of the digestive system in the belly. This will cause the belly to look bloated and called "beer belly" or "central obesity". The fat is also located in the subcutaneous part of the skin.

Thus, option "B" is correct.

A possum playing dead to increase its chances of survival organism exhibits behavioral adaptation.  Correct Option is 2.

Behavioral adaptations refer to the actions or responses exhibited by organisms in response to their environment or specific stimuli to improve their chances of survival and reproduction. Among the options provided, choice B, a possum playing dead to increase its chances of survival, best represents a behavioral adaptation.

When a possum plays dead (a behavior known as "playing possum" or "playing dead"), it is exhibiting a defensive response to threats or predators. When confronted by a potential predator, a possum will feign death, becoming limp and unresponsive. This behavior can deceive predators into thinking that the possum is no longer a threat or potential prey, giving the possum a chance to escape from danger.

Explanation: the skin is made up of tissue

The skin is made up of tissues with different functions that work together. So, the correct option is (C).

Skin is defined as the largest organ of the body where skin and its derivatives such as hair, nails, sweat and oil glands form the integumentary system. The main function of the skin is protection which protects the body from external factors such as bacteria, chemicals and temperature.

The skin is made up of water, proteins, fats and minerals that protect the body from germs and regulate body temperature. Skin nerves help to feel sensations like hot and cold.

It is made up of three layers, the epidermis, dermis and hypodermis which are anatomically distinct. Its structure is made up of a complex network that serves as the body's initial barrier against pathogens, UV light and chemicals, and mechanical injury.

Thus, the skin is made up of tissues with different functions that work together. So, the correct option is (C).

Answer:

through changes in the availability or activity of the "helper"

Explanation:

This process involves many "helper" proteins, which make sure the ribosome is correctly positioned. Translation can be regulated globally (for every mRNA in the cell) proteins.

During dehydration synthesis, an enzyme removes a hydroxyl  functional group from the monomers of one organic molecule and a hydrogen (H) from another monomer, linking monomers together to form a polymer. This chemical reaction also forms water molecules as byproducts.

An enzyme removes a hydroxyl (-OH) group from one monomer and a hydrogen (H) from another during dehydration synthesis, allowing the monomers to form a polymer. This mechanism bonds monomers covalently and produces water molecules. Complex biological components including proteins, nucleic acids, and carbohydrates depend on dehydration synthesis.

Eliminating water molecules strengthens chemical connections, making it easier to assemble bigger structures from smaller components. This response aids energy storage, structural stability, and information flow in living things.

"We may not know about all organisms present in the ancient world since not all organisms on Earth can be fossilized". The best statement is that Organisms that have soft bodies decay before they fossilize.

The animals represented via way of means of those newly found fossils, which include sponges, annelid worms, mollusks, and horseshoe crabs, lived at some stage in the Ordovician length among 480 million and 472 million years ago, making them the oldest ever found at some stage in this length.

For a soft-bodied animal to be fossilized, its frame should be blanketed from decomposition. The frame is typically uncovered to air and water with quite a little oxygen, so it decomposes rapidly. The animal is probable to be fossilized best if it's miles buried quickly after it dies (or whilst it's miles buried may be fossilized.
