Answer:
In addition to lipids, membranes are loaded with proteins. In fact, proteins account for roughly half the mass of most cellular membranes. Many of these proteins are embedded into the membrane and stick out on both sides; these are called transmembrane proteins.The cell membrane contains a phospholipid bilayer, but the terms are not interchangeable.In addition to the phospholipids, the plasma membranes of animal cells contain glycolipids and cholesterol. ... Because the interior of the phospholipid bilayer is occupied byExplanation:
The principal components of the plasma membrane are lipids (phospholipids and cholesterol), proteins, and carbohydrate groups that are attached to some of the lipids and proteins.Adjustments to timber management strategies meant to address long-term shortfalls will _______.

What else do you think plants may need to grow and go through their normal processes?
Plants need water, oxygen, soil, and solar energy.
Those are the only things that I believe plants need. They need water for food and Solar Energy (basically Vitamin D which you get from the sun) and soil to grow. Obviously they need oxygen to be able to survive.

Thoroughbreds are an example of a type of horse that results from selective breeding. However, not all thoroughbreds have the traits that are most desired. How has the process of selective breeding increased the probability that the horse will have a desired trait? Use information from the stimulus material and your knowledge of science in your answer. In your answer, be sure to:
Explain how selective breeding increases the probability that offspring will have a desired trait.
Explain why not all individual thoroughbreds may express the desired traits.
Answer:
If breeders Breed these horses with other breeds, the foal wont be a straight thoroughbred. So, it will change the horses breed.
Explanation:
Selective breeding increases the probability that offspring will have the desired trait because it limits narrows the gene pool to only include desired variants of a gene. Not all thoroughbreds may express the desired trait because they may inherit an unwanted variant of the gene & mutations may occur.
The traits and characteristics of an animal are determined by the genes they possess. When two animals breed, the offspring inherits one variant of each gene from both parents, known as alleles. This means that all animals have 2 variants for any specific trait.
When a gene in an allele is expressed, it means that the genetic code in that allele is the one that can be seen on the offspring. Gene variants can be classified based on how likely they are to be expressed as:
Dominant RecessiveWhen one allele is expressed and the other is not, it is because that allele is dominant and the other is recessive. Recessive variants for a gene will only be expressed if both alleles inherited by the offspring possess are recessive. dominant genes are symbolized by a capital letter and recessive genes with a lower-case letter.
Selective breeding is used to continuously breed animals that have similar variants of the desired trait. If breeding were to be natural, then many of what we consider desirable traits may be lost behind the expression of common, more dominant genes. Selective breeding is done by narrowing the gene pool, meaning that we only allow breeding between animals known to possess the desired trait.
Not all thoroughbreds may express the desired traits because sometimes even though a parent has the desired variant of a trait, they may also contain a different recessive or dominant variant of a trait. Since selective breeding does not control what variant exactly the offspring inherits, it does not always work with each offspring. Genetic mutations can also affect the outcome.

Why do plants use gravity?
Answer:
Gravity perception is important to plants because they need to send their roots downwards towards water and nutrients and their shoots upwards towards light. Plants are known to detect gravity using statelets, which are small starch-filled packets that settle at the bottom of gravity-sensing cells

What is one function of the organ system shown below in the picture?
The circulatory and respiratory systems are involved in respiration. They provide oxygen to the body cells and remove carbon dioxyde. The correct option is A. To remove carbon dioxyde from the body.
Two systems work together when providing oxygen to the body cells and removing carbon dioxide: The circulatory and respiratory systems
• Respiratory systemThis system is in charge of the gasses interchange. It takes oxygen from the air and releases carbon dioxide.
• Circulatory systemThis system is in charge of driving oxygen to the organism's tissues and cells and taking away carbon dioxide from them.
These gases are in the oxygenated and deoxygenated blood, respectively.
The heart bombs blood through arteries, veins, and capillaries to the whole body.
The blood carries oxygen to different tissues.
This oxygen is absorbed in the lungs and proceeds from the air that we breathe. Its final destiny is all the cells in the organisms.
Types of circulation• Lung circulation
1. Moves blood between the heart and the lungs.
2. Deoxygenated blood goes from the heart to the lungs
3. In the lungs, deoxygenated blood releases carbon dioxide and gets oxygenated again.
4. Carbon dioxide is released by exhalation.
5. Blood absorbs oxygen from small air sacs named alveoli.
6. Oxygenated blood returns to the heart.
• Systemic circulation
1. Carries blood between the heart and the rest of the body.
2. Oxygenated blood leaves the heart and moves to all the cells in the body.
3. Deoxygenated blood returns from tissues to the heart.
According to thi framework, the function of the organ system shown in the picture is to remove carbon dioxyde from the body. Option A.

Choose the CORRECT statement about enzymes below.
Group of answer choices
Enzymes raise the activation energy needed in a chemical reaction
Enzymes slow down the rate of chemical reactions
Enzymes function best at specific pH and temperatures
Enzymes are carbohydrates and store short term energy
Answer:
Enzymes function best at specific pH and temperatures.
Explanation:
An enzyme can be defined as a biological catalyst that typically lowers the activation energy of a biological reaction. When the activation energy of a reaction is low, the rate of the reaction would be faster. Therefore, an enzyme speeds or catalyzes the rate of a reaction by lowering its activation energy.
Also, if the conditions are not optimal for an enzyme, it limits the ability of an enzyme to bind or be joined with its substrates.
Hence, the correct statement about enzymes is that enzymes function best at specific pH and temperatures. An increase in temperature increases or speeds up the rate of a reaction while low temperature limits or reduces the rate of a reaction. The optimal temperature for enzymes in the human body is around 37 degrees celsius.

Which of the following statements about human society and limiting factors is true?
a. Modifications made to the environment to reduce the impact of limiting factors can cause
disruption to the natural balance of an ecosystem.
b. Humans cannot modify their environment to adapt it to their needs.
c. Humans can completely overcome the factors that limit population size.
d. Limiting factors are of no concern to human society, because they do not affect human
populations
The statement that is true about human society and limiting factors is "Modifications made to the environment to reduce the impact of limiting factors can cause disruption to the natural balance of an ecosystem." The correct option is A.
What are limiting factors?Limiting factors are the factors that limit the growth of populations. For instance, the limiting factors for humans might be a lack of food or water. Limiting factors may be biotic or abiotic. Abiotic factors include nonliving aspects like temperature and rainfall while biotic factors are the living aspects like predators and competition.
Modifications made to the environment to reduce the impact of limiting factors can cause disruption to the natural balance of an ecosystem. These modifications include the introduction of a new species, the clearing of land for agriculture or industry, or pollution.
The new species can lead to the elimination of the native species, the clearing of land can cause habitat loss, and pollution can have numerous effects like air and water pollution.
Therefore, the correct option is A.
