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.

Which of the following scenarios is representative of parasitism? A.Tapeworms living in mammal's intestinal tract B.Remora fish attaching themselves to sharks C.Birds feeding on insects stirred up by grazing animals D.Birds eating scraps of food from crocodile's teeth
Answer:
A- Tapeworms living in a mammal's intestinal tract.
Explanation:
Parasitism is a symbiotic relationship between species, where one organism, the parasite, lives on or in another organism, the host, causing it some harm, and is adapted structurally to this way of life.

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.

HELP YALL I NEED IT QUICKKKKK Hybrid seeds are deliberately crossbred for particular traits, such as growth pattern or disease resistance. They have been hand-pollinated and are patented, often sterile, and genetically identical within food types. These plants are usually grown in a monocultural environment and are cultivated for mass production and sale. They must be sturdy to withstand mechanical picking and cross-country shipping. They do not compare to the quality and taste of heirloom plants, but they do produce large, healthy fruit that appeals to most shoppers. Unlike heirloom seeds, if one saves a hybrid seed, one will not get the same plant again.
Which statement can be removed and not affect the excerpt’s reliability?
Answer:
Unlike heirloom seeds, if one saves a hybrid seeds, one will not get same plant again.
Explanation:
Hybrid seeds they are cross pollinated. It is the main contributor in agriculture.
They does not reproduce so they do not save seeds from hybrids.
Heirlooms are open pollinated. Thy can be harvested and replanted and it can be grown year after year.

Energy is released from ATP when a phosphate group is removed.
true or false?
Yes! True!
[From nature.com] "When one phosphate group is removed by breaking a phosphoanhydride bond in a process called hydrolysis, energy is released, and ATP is converted to adenosine diphosphate (ADP). Likewise, energy is also released when a phosphate is removed from ADP to form adenosine monophosphate (AMP)."

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.

Cell Observations
Cell X Cell Y
has lysosomes lacks lysosomes
lacks a cell wall has endoplasmic reticulum
has ribosomes has a nucleus
Which additional observation will Alyssa most likely make?
Cell X has a cell membrane, and Cell Y does not.
Cell Y has a cell membrane, and Cell X does not.
Cell Y has a larger vacuole than Cell X.
Cell X has a larger vacuole than C
Answer:
Cell Y has a larger vacuole than cell X
Explanation:
Cell Y is the plant cell, only plant cells have a tough and rigid cell wall, animal cells do not. The observation that Cell X lacks a cell wall as well as having lysosomes is indication that Cell X is an animal cell. The answer that Cell Y has a larger vacuole is true because plant cells need to store more water and nutrients than animal cells and will have a much larger vacuole.

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

Witch of the following would introduce a bias into an experiment?
A. Publishing your experimental results in a scientific journal.
B. Allowing other scientist to repeat and verify your experimental results.
C. Using a computer to record and store your data.
D. Discarding data that does not fit with your personal expectations.
Answer:
D. Discarding data that does not fit with your personal expectations.
Explanation:
One of the ways in which bias can be introduced into an experiment is by discarding data that does not fit with one's personal expectations.
Bias in an experiment is the process whereby scientists alter the results of their experiment to achieve their own expected results.
Anomalous values defined by one's expectation can make an experiment highly biased. A scientist is supposed to be objective in their experimental approaches.FIRST GETS BRAINLEIST!!

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.

The warming of the atmosphere by the trapping of heat being radiated to space is called
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.
