What is never found inside the lipid bilateral of a cell membrane
Answer:
Cell membranes restrict diffusion of highly charged molecules, such as ions, and large molecules, such as sugars and amino acids.
Explanation:
Cell membranes serve as barriers and gatekeepers. They are semi-permeable, which means that some molecules can diffuse across the lipid bilayer but others cannot. Small hydrophobic molecules and gases like oxygen and carbon dioxide cross membranes rapidly. Small polar molecules, such as water and ethanol, can also pass through membranes, but they do so more slowly. On the other hand, cell membranes restrict diffusion of highly charged molecules, such as ions, and large molecules, such as sugars and amino acids. The passage of these molecules relies on specific transport proteins embedded in the membrane.
If you took a 20-foot tree and hammered a spike into it 3-feet above the ground, how high would that spike be 30 years later when the tree is 100 feet tall? and why?
Answer:
The spike will remain at 3-feet above the ground in 30 years time because the spike does not increase in height as the tree does.
Please find the explanation below
Explanation:
Living things including the trees stated in this question are capable of growth (in height and girth). According to this question, a spike is hammered into a tree base at 3-feet above the ground level. However, after 30 years, the tree grows to 100 feet but the spike will remain at 3-feet above the ground.
This is because the spike, which is naturally incapable of growth, will not grow alongside the tree. A plant (tree) undergoes growth at its apices or meristem i.e. the tree will elongate from the tip and not any other part. Hence, the tree will grow and leave the spike at its initial level.

How does the polarity property make hydrogen bonds between water molecules possible?
Answer:
The two hydrogen atoms and one oxygen atom within water molecules (H2O) form polar covalent bonds. ... As a result of water's polarity, each water molecule attracts other water molecules because of the opposite charges between them, forming hydrogen bonds.
Explanation:

(1) Cell differ in shape and size
Answer:
Cells have different shape and size because different cell types have different functions. For example : Red blood cells are shaped like a doughnut to carry more hemoglobin, and to fit through small spaces, and neurons are long and skinny to span wide places to send signals around the body .

2. Do you think rapid or gradual environmental changes have a greater potential to affect
an organism's niche? Explain your answer.
Answer:
ofc it does !!
Explanation:
when the environment changes that specific animal niche will most likely change due to it being such a drastic change. for example when let's say the hunting rates have increased alot and that results in the drastic decrease of mice, well that was the main source of food that the foxes were getting and will make the move environments and change their diet drastically cause they cant find their regular diet. i hope this is what u were asking !

If a diploid tomato cell has 24 chromosomes, how many chromosomes will the tomato's sex cells have?a.12c.24b.6d.48
Answer:
12!
Explanation:
Sex cells only carry half of what makes up the organism's DNA. This is so that when they find a mate, in this case- another tomato, their sex cells and their partner's sex cells will add up to the appropriate amount of chromosomes in the organism's DNA. In this case, 24.

Sharks are often followed by smaller fish that eat some of the scraps from the organisms eaten by the shark. These smaller fish are acting as
Answer: they are acting as scavengers, by finding food nearby without hunting it for themselves.
Explanation: hope that answered your question.
These smaller fish are acting as commensalism, that is, they eat the remains left by the sharks.
What is the relationship between the shark and the Pilot Fish?As the name suggests, the pilot fish takes advantage of the food scraps left by the shark when it attacks its prey to feed itself.
Commensalism is a type of interspecific ecological relationship, as it occurs between individuals of different species. In this type of ecological relationship there is no harm to any of the species involved, remembering that only one of the organisms involved benefits.

Answer:
The third answer choice
Different forms of the same gene.
Explanation:
An allele is an alternative form of a gene (one member of a pair) that is located at a specific position on a specific chromosome. These DNA codings determine distinct traits that can be passed on from parents to offspring.
Answer:
An allele is a one of many different forms of a gene that arise by mutation and are found at the same place on a chromosome.

What features do we find only in the cells of bacteria?
What features do we find only in the cells of animals?
What features do we find only in the cells of plants?
Answer:
In bacteria cells, you would find pili (only found in bacteria and archaea) and DNA not contained in a nuclear envelope/nucleus. These are, for the majority, exclusively found in bacteria cells.
In animal cells, you would find lysosomes and centrosomes. These organelles are exclusively found in animal cells.
In plant cells, you would find plastids, such as chloroplasts or amyloplasts. More specifically, chloroplasts are exclusively found in plant cells as they are necessary for photosynthesis to occur.
During glycolysis, glucose is broken down into two molecules of pyruvate.
A diagram shows the conversion of a glucose molecule to 2 pyruvic acid molecules. In this process, 2 A T P form 2 A D P, 2 N A D produce 2 N A D H, and 4 A D P produce 4 A T P.
What is the main transformation that occurs during glycolysis?
Answer:
Glycolysis produces ATP, pyruvate, and NADH by oxidizing glucose.

answer the following questions regarding the organism that the product is derived from (reasonable guesses or
speculation is ok):
1. What is the organism?
2. Where does the organism live?
3. Briefly characterize the ecosystem that the organism lives in.
4. Provide one example of how the organism depends on another organism.
5. What are some threats to the organism in the ecosystem?
Speculate on how your life would be affected if the organism became extinct.
Answer:
1. An organism is a individual animal, plant, or single-celled life form.
2. Habitat, place where an organism or a community of organisms lives, including all living and nonliving factors or conditions of the surrounding environment. Like a forest, lake, coral reef, desert, towns or cities.
3. An ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscape, work together to form a bubble of life. Ecosystems contain biotic or living, parts, as well as abiotic factors, or nonliving parts. Biotic factors are animals, trees, plants, and abiotic factors are things that have never been alive. So rock rivers, ponds, man made objects.
4. When a organism depends on another is called symbiotic relationships. There are three different types of symbiotic relationships: mutualism, commensalism, and parasitism. Mutualism: both partners benefit. An example of mutualism involves goby fish and shrimp. The shrimp maintains a burrow in the sand in which both the fish and shrimp live. When a predator comes near, the fish touches the shrimp with its tail as a warning. Then, both fish and shrimp retreat to the burrow until the predator is gone.
5. Pollution(water&air), deforestation, UV Radiation, invasive species.
If an organism went extinct the next generation won't ever be able to see those organisms. If an organism we eat went extinct we would have one less food source which is something that really does not need to happen in today world.

I chose the product cotton pants. The responses are:
Cotton plant
Southeastern North America
The plant lives in soil in an agricultural field.
The cotton plant requires bees for pollination.
The plant may be threatened by diseases such as cotton leaf curl disease, pests such as aphids, and drought.
If cotton became extinct, my pants would have to be made of some other material, such as linen or wool, which would feel quite different. This would be a big adjustment for me because I am used to wearing cotton pants almost every day.
