1. How is it possible for a phospholipid to be hydrophilic and hydrophobic? (2)
1

Answers

Answer 1
Phospholipids consist of a glycerol molecule, two fatty acids, and a phosphate group that is modified by an alcohol. The phosphate group is the negatively-charged polar head, which is hydrophilic. The fatty acid chains are the uncharged, nonpolar tails, which are hydrophobic.

How do the properties of water and the ability to modify the rates of chemical reactions enable living things to carry out functions necessary for life, such as digesting food?

Answers

Answer:

A chemical reaction is a process that changes some chemical substances into others. It involves breaking and reforming chemical bonds. They follow the Law of Conservation of Matter.

Explanation:

Energy is a necessity for all living organisms to survive, and ATP is a reactant that powers several other chemical processes inside cells. Cellular respiration is the method used by cells to produce energy.

What attributes of water are requisite for an organism?

The term “universal solvent” refers to water's enormous capacity to dissolve a wide range of molecules, and it is this capacity that makes water such a priceless life-sustaining agent.

Water has five key characteristics: strong polarity, high specific heat, high heat of vaporization, low solid density, and affinity for other polar molecules.

The process of converting one chemical substance into another is known as a chemical reaction. Chemical bonds are broken and rebuilt in this process. The Law of Conservation of Matter is observed by them.

Therefore, Water's function as a solvent aids cells in the transfer and utilization of chemicals like oxygen and nutrients on a biological level.

Stella described protein synthesis as a process that makes the necessary proteins for the human body to function. She
explained the process in the following steps.
1. DNA is transcribed into mRNA.
2. Amino acids form a chain.
3. The amino acid chain is folded into a protein in the endoplasmic reticulum.
What step did Stella miss in her explanation?
(1 point)
O Polypeptide chains express gene traits.
O tRNA delivers the DNA to the ribosome.
hy
O DNA is replicated into two daughter cells.
O mRNA is translated into amino acids.

Answers

The step of protein synthesis missed by Stella would be the translation of mRNA into amino acids.

The process of protein synthesis can essentially be divided into 2, namely:

TranscriptionTranslation

During transcription, genetic information on DNA is transcribed into mRNA. Once this is done, the genetic codes in mRNA are then translated to their respective amino acids and linked by peptide bonds.

The polypeptide bond undergoes further processing such as folding in the endoplasmic reticulum.

Thus, before amino acids can form a polypeptide chain, they must first be translated from genetic codes in mRNA.

The properties of photosynthetic pigments that allow pigments to absorb light of only certain wavelength is ; ( B and D ) 

Only light with the correct wavelength to boost an electron of the pigment to a higher energy level is absorbed.All pigment molecules possess a light-trapping region with a special structure that allows electrons to move freely between Its atoms.

The Green pigment found in plants ( i.e. photosynthetic pigment )  that absorb light energy used by plants during  photosynthesis is the chlorophyll. It absorbs light energy based on the wavelength of the visible light while reflecting visible green light due to its wavelength.

The reflection of the visible green light by the chlorophyll gives the plants leaves the green color it possesses.

Hence we can conclude that The property of photosynthetic pigments that allow pigments to absorb light of only certain wavelength is ; Only light with the correct wavelength to boost an electron of the pigment to a higher energy level is absorbed. and statement D.

2. Producers are living things that use energy to make food. Producers make food for themselves and other living things.

3. the difference between a herbivore and an omnivore is a herbivore eats only plants or producers, and an omnivore eats both plants, and other animals/consumers.

4.A food chain follows one path of energy and materials between species. A food web is more complex and is a whole system of connected food chains. In a food web, organisms are placed into different trophic levels.

What happens when oxygen, carbon dioxide and glucose molecules diffuse across the cell membrane? Explain in your own words

Answers

Answer:

Simple diffusion is responsible for the spread of an air freshener through a room, or of a few drops of dye to eventually turn a glass of water a uniform color. Molecules naturally disperse from areas of higher concentration to lower concentration.

As oxygen-rich (and carbon dioxide-poor) blood travels by a cell the oxygen diffuses through the cell membrane to the area of lower concentration inside the cell. It can do this easily because the oxygen molecule (O2) is very small and has no charge or polarity. The oxygen is used up rapidly by mitochondria. This rapid consumption causes oxygen to constantly move into the cell from the blood.
