What are three possible long-term consequences of two species occupying the same niche?
Answer:
one will become extinctone/both will adaptone will migrate to a new locationExplanation:
An ecological niche is the role species has in its environment. This includes how it survives, reproduces, finds shelter, and obtains good. It includes all its interactions with both biotic (living) and abiotic (non-living) factors.
When species occupy the same niche, it means they are competing for the same resources. This is not sustainable. Eventually, one of three things are likely to happen:
one species will die out (become extinct) because they are being outcompeted by the more successful species, and will struggle to survive without adequate food and sheltereither one or both species will have to adapt to occupy another similar niche by, for example, exploiting a new food source in the area.either one or both species will have to migrate to a new area to occupy a different geographical area and new resources.The species that is being excluded from the niche can either adapt in the long term to occupy another similar niche, migrate to a new area, or it can die out.
Answer: The species that is being excluded from the niche can either adapt in the long term to occupy another similar niche, migrate to a new area, or it can die out.

What describes G and why they face the watery inside and outside of the cell
Answer:
Because they are hydrophilic
Explanation:
The cell membrane is made up of a phospholipid bilayer. The phospholipid bilayer is made up of an arrangement of phosphate heads, which are (attracted to water) hydrophilic, and fatty acid tails, which are hydrophobic. (repelled by water).
Because they are attracted to water, the phosphate heads face the outside of the cell, where the water is

Cholesterol is synthesized by all animal cells and is an essential structural component of animal cell membranes. Cholesterol is the most common steroid and is mainly synthesized in the liver. Cholesterol also serves as a precursor for several important biological compounds including all, EXCEPT: A) insulin B) vitamin D C) bile salts D) testosterone
the answer is insulin. because the precursor for insulin is called pro insulin
Cholesterol does not serve as the precursor for insulin. So the correct option is A.
What is cholesterol?Cholesterol is a wax-like substance. Cholesterol is considered to be bad among the general public but it is not inherently “bad.” Our body needs for building cells and making vitamins and several other hormones. Cholesterol levels, in excess, can pose a problem.
Cholesterol can come from two sources. These are synthesized by the liver and from foods from animals. The liver produces all the required cholesterol but the remainder is obtained from foods. For example, meat, poultry, and dairy products of them contain dietary cholesterol.
These are the same foods that are also high in saturated fats and trans fats. These fats cause the liver to make more cholesterol than required or more than it normally does. This added production of cholesterol, for some people, means they go from a normal level of cholesterol level to unhealthy level of cholesterol.
Therefore the correct option is A.

Cytoplasm contains the cytosol, microfilaments and other support structures in the cytoskeleton; it holds parts of the cell together.
What is cell wall?Cell wall is the rigid outer layer of the cell; this forms a protective wall made mostly of cellulose, a structural carbohydrate. It maintains the shape of the cell by preventing water loss. Vacuole a phospholipid membrane bound organelle plays a structural role in the cell; supports the cell membrane by exerting turgor pressure.
Arranged in a phospholipid bilayer, the cell membrane is semi-permeable; allowing entry into the extracellular fluid or the cytoplasm which are both hydrophilic and contain large concentrations of polar water molecules or other water-soluble compounds.
The hydrophilic heads of the bilayer are attracted to water while their water-repellent hydrophobic tails face towards each other- allowing molecules of water and hydrophilic molecules to move across the membrane along the concentration gradient.
Therefore, Some organelles are bound by membranes like those that make up the external structure of the cell, with varying compositions of phospholipids and proteins.

A “valve” called the lower esophageal sphincter (LES) is located just before the opening to the stomach. This valve opens to let food pass into the stomach from the esophagus and it prevents food from moving back up into the esophagus from the stomach.
What causes sea floor to spread apart at mid ocean ridges?
Answer:
Seafloor spreading occurs at divergent plate boundaries. As tectonic plates slowly move away from each other, heat from the mantle's convection currents makes the crust more plastic and less dense. The less-dense material rises, often forming a mountain or elevated area of the seafloor.
how are proteins made in animals and humans
Answer:
Through protein synthesis of course...
Explanation:
DNA and RNA do many steps such as translation, transcription, and more to form protein codons and code them into amino acids. Then, thousands of amino acids are oined together to make proteins, which regulate body function and catalyze chemical reactions (enzymes). Ribosomes are also involved in this action. To make proteins, nitrogen is needed for the plant to use, and that comes mainly from nitrate ions in the soil, and gets into the plant by active transport.
Which of the following is true:
- Since the active site has a specific shape it can only fit one substrate.
- The active site can fit any type of substrate.
- Nothing can fit or bond with the active site of an enzyme.
Answer: Since the active site has a specific shape it can only fit one substrate.
Explanation: I took one for the team on Ed puzzle.
Since the active site has a specific shape it can only fit one substrate. The correct option is A.
What is active site of enzyme?The active site is the region of an enzyme where substrate molecules bind and undergo a chemical reaction in biology and biochemistry.
The active site is made up of amino acid residues that form temporary bonds with the substrate (binding site) and residues that catalyze the substrate's reaction (catalytic site).
The active site of an enzyme is the specific region of the enzyme where a substrate binds and catalysis or chemical reaction occurs.
It is a protein structural element that determines whether the protein is functional when subjected to an enzyme reaction.
A holoenzyme is a fully active enzyme that is made up of a protein portion (apoenzyme) and a cofactor.
Thus, the correct option is A.

In one plant species petal color follows INCOMPLETE DOMINANCE. If there
are alleles for both red and white plants, what would a heterozygous plant's
phenotype be?
Red
Pink
White
Red and White
Answer:
Pink
Explanation:
Incomplete dominance is when one allele is not entirely dominant over the other. The resulting phenotype of the heterozygote is intermediate between the two alleles. That means the flowers would be pink.
Red - no, this would be true if red was dominant to white
Pink - yes, this is an intermediate phenotype
White - no, this would be true if white was dominant over red.
Red and White - no, this would be true if the alleles were co-dominant and both equally but independently expressed.

a)condensation
b)evaporation
c)the greenhouse effect
d)radiation
Answer:
The greenhouse effect is a process that occurs when gases in Earth's atmosphere trap the Sun's heat. This process makes Earth much warmer than it would be without an atmosphere. Solar energy absorbed at Earth's surface is radiated back into the atmosphere as heat. As the heat makes its way through the atmosphere and back out to space, greenhouse gases absorb much of it.
