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.

What is protein?
Protein has been defined as the large macromolecules as well as biomolecules that are used to made up of the long chains of the amino acid. There has been various function of the protein such as the DNA replication, speeding up of chemical reaction which helps to maintain the structure of cell.
The main function of the protein has to maintain the structure and function of the organs, repair muscle, and the muscles. Diet contains high protein has been recommended for the purpose of losing weight, reducing fat, or increasing fat.
There are several types of the protein such as the structural protein, transport proteins, antibodies, contractile proteins, hormonal proteins, and enzymes.
Therefore, Both protein and carbohydrate molecules tend to form chains. These chains differ in that protein chains are composed of amino acids, and carbohydrate chains are composed of sugars. Thus, option D is correct.

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.

If an organism is multicellular, it probably has
A.) Prokaryotic cells
B.) Eukaryotic cells
C.) Cancer cells
D.) All of the above
Answer:
B. Eukaryotic cells
Explanation:
Prokaryotic cells are only seen in unicellular organisms as bacteria and cancer cells are just cells where there has been an error in division or a mutation.
If an organism is multicellular, it probably has - option B.) Eukaryotic cells.
Cells are of mainly two types prokaryotic cells and eukaryotic cells. The main difference between eukaryotic and prokaryotic cells is that:
Eukaryotic cells have a nucleus in which genetic material is stored enclosed by a nuclear membrane.All prokaryotic cells only form single-celled (unicellular) organisms without a true nucleus or membrane-bound structures, examples of prokaryotes are bacteria and archaea. Organisms with eukaryotic cells are called eukaryotes that can be either multicellular such as animals, plants, fungi, and protists, or single-celled as well. So, all multicellular organisms are eukaryotes..Thus, If an organism is multicellular, it probably has - option B.) Eukaryotic cells.

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.

Answer:
d.Blue light has a shorter distance between wave crests than orange light.
A. Red light has a longer distance between wave crests than blue light.
Explanation:Make sure u read!!!!
The correct answers are C. Blue light has a longer distance between wave crests than red light, and E. Orange light has a shorter distance between wave crests than violet light.
What is visible light?Visible light waves are a type of electromagnetic radiation that are visible to the human eye. They make up a small portion of the electromagnetic spectrum and have wavelengths that range from about 400 nanometers (nm) to 700 nm. Visible light waves can be separated into colors of the rainbow, including red, orange, yellow, green, blue, indigo, and violet.
Each color of visible light has a unique wavelength and frequency. Red light has the longest wavelength and the lowest frequency, while violet light has the shortest wavelength and the highest frequency. This means that red light has a longer distance between wave crests than violet light, and violet light has a shorter distance between wave crests than red light.

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 !
