Answer;
The substance that can enter a cell by diffusion without having to be digested is water.

Explanation;
Diffusion involves the movement of molecules from a region of high concentration to a region of low concentration, down a concentration gradient.
Water is able to diffuse through the cell membrane without being digested since it has small molecules.
One property of cell membrane is semi-permeability; it selectively allows material to enter or leave the cell. Large molecules such as starch , fat and proteins, can not enter the cell due to their size and will need to be digested to small molecules for the to gain access to the cell.

Answer:

Jake is correct.

Explanation:

Sophie is wrong because although dolphins and sharks can technically be said to be similar, it resulted from convergent evolution, which has nothing to do with common ancestry and rather to do with similar environments for their homes.

What specifically is this biochemical used for, and how is it broken down during digestion?
Cerrena [4.2K]
Digestion occurs in the stomach and the duodenum through the action of three main enzymes: pepsin, secreted by the stomach, and trypsin and chymotrypsin, secreted by the pancreas.During carbohydrate digestion the bonds between glucose molecules are broken by salivary and pancreatic amylase.The digestion of certain fats begins in the mouth, where short-chain lipids break down into diglycerides because of lingual lipase. The fat present in the small intestine stimulates the release of lipase from the pancreas, and bile from the liver enables the breakdown of fats into fatty acids.DNA and RNA are broken down into mononucleotides by the nucleases deoxyribonuclease and ribonuclease (DNase and RNase) that are released by the pancreas.

irina [24]

Answer:

b. False

Explanation:

All biomes, even the most remote, are affected by the impact humans have on the environment.

Humans have been causing deforestation, pollution, agricultural expansion, mining, desertification, extinction of animals and plants, burning and other practices that have had extremely negative impacts on biomes around the world. In addition, all the pollution and exploitation of nature that humans have caused has caused harmful climate change that has affected even the most remote biomes.

The biome is a large set of interconnected ecosystems. Ecosystem, in turn, is an ecological system where there is life and interaction between living beings in a given space, and can vary in size, from a puddle to a large forest.
