How would you describe dominant in a different way then this? In a easy way?
Refers to a trait that appears more frequently than another trait, resulting from interactions between gene alleles.
Answer:
A dominant allele is a variation of a gene that will produce a certain phenotype, even in the presence of other alleles. A dominant allele typically encodes for a functioning protein. The allele is dominant because one copy of the allele produces enough enzyme to supply a cell with plenty of a given product.
Which animals have adapted to near-freezing water?
A. Barnacles
B. Animals in coral reefs
C. Fishes in polar areas
D. Whales
Answer:
C/D
Explanation:
Unfortunately, I can't give a straight answer since it doesn't specify if the fish belongs in the water, all I know it that it's a plain fish in polar water. So D is probably the answer. Since some whales live in polar areas.

Explanation:
because thats what I think the answer can be
B. pluripotent stem cell. Pluripotent stem cells are a type of stem cell that have the ability to differentiate into many different types of cells, including blood cells.
What are pluripotent cells?Pluripotent stem cells are a type of stem cell that have the ability to differentiate into many different types of cells, including blood cells. They are "pluripotent" because they can give rise to many different cell types, as opposed to more specialized stem cells, such as multipotent stem cells, which can only differentiate into a limited number of cell types.
Pluripotent stem cells are important because they have the potential to be used for regenerative medicine and to treat a wide range of diseases, such as blood disorders, cardiovascular disease, and neurodegenerative diseases. They can also be used to study early human development and to understand the underlying mechanisms of disease.

The cell will ____________ in CORN SYRUP because _____________________________________________________.
Answer:
The cell will shrink because water can move in but proteins cannot move out.
Explanation:
Since the egg membrane is semi-permeable, water can move in but proteins cannot move out. If a naked egg is placed in the corn syrup the egg will shrink. This is also due to osmosis, but in the opposite direction. The corn syrup is mostly sugar.
Why must cells divide to stay small or change shape to reduce volume?
O To diffuse substances from an area of higher to lower concentration
To ensure the cell is able to obtain nutrients or remove wastes.
To reduce surface area of the cell for quick movement.
O To move water molecules from areas of high to low pressure
Answer:
if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume. When this happens, the cell must divide into smaller cells with favorable surface area/volume ratios, or cease to function. That is why cells are so small.
Explanation:
Answer:
To ensure the cell is able to obtain nutrients or remove wastes.
The important point is that the surface area to the volume ratio gets smaller as the cell gets larger. Thus, if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume That is why cells are so small.

Insta: 25k_kemWhich factor may increase a rabbit population?(1 point)
decrease in space
decrease in temperature
decrease in food
decrease in predators
Answer:
D. Decrease in predators
Explanation:
The lack of predators would cause less death to the rabbit population, with less hunters to kill the rabbits the population will increase and further increase if they reproduce.
The factor that will increase a rabbit population is ( D ) Decrease in predators
Rabbits as primary consumersRabbits are herbivores that feed on nuts and grasses they are primary consumers and are prey to so many secondary and tertiary consumers ( i.e predators ).
A decrease in space will result to lose of habitat and this will decrease the population of rabbits also extreme weather conditions might lead to death of rabbits just like decrease in food will cause starvation and eventual death for rabbits as well.
While a decrease in predators will result in the survival of more rabbits ( i.e increase in population )
Hence we can conclude that The factor that will increase a rabbit population is Decrease in predators.

A. transcription
B. translation
The nucleus is the site of transcription in protein synthesis.
What do you mean by Transcription?Transcription may be defined as a process through which a cell makes a copy of RNA (mRNA) from a strand of the DNA.
These messenger RNA carries the genetic information which is essential to make a protein in a cell. The process of transcription occurs in the nucleus of the cell.
While translation is the process by which the sequences of mRNA may transform into proteins. This process occurs in the cytoplasm of the cell.
Therefore, the nucleus is the site of transcription in protein synthesis.

Both the liver and kidneys are organs of the excretory system. How do the two organs work together to complete a task?
Answer:
When the liver has broken down due to harmful substances, its by-products are exerted into the bile or blood. Bile by-products enter the intestines and leave your body in the form of feces. Blood by-products are filtered out through the kidneys and leave the body in the form of urine.
Explanation:
When the liver is damaged by harmful substances, their by-products move into the bile or blood, where the by-products of bile enter the intestines and leave your body as feces and by-products of the blood. -products are filtered through the Kidneys and leave the body as urine.
What is Excretion?Excretion is defined as the process in which metabolic waste is eliminated from an organism, this is done by the lungs, kidneys and skin in vertebrates.
This is in contrast to secretion, where matter may have specific functions after leaving the cell where excretion is an essential process in all forms of life.
Through excretion organisms control osmotic pressure which is defined as the the balance between inorganic ions and water and maintain acid-base balance.
Thus, when the liver is damaged by harmful substances, their by-products move into the bile or blood.

1: What gases are used and expelled by photosynthesis and respiration?
2: Where are the largest concentration of ozone and what value does it have?
3: What happens to the surface of the earth when there is an increase in greenhouse gases?
Answer:
1 Photosynthesis uses CO2 and expels O2 and the reverse for respiration
2. stratosphere where ~90% of it is
3. Less infrared radiation is able to escape from the earth into space and that infrared radiation hits the GHG gases and the radiation is turned into kinetic or heat energy trapping which warms up the earth
Explanation:
Answer:
1. Used by Photosynthesis: CO2 Expelled: O2
Used by Cellular respiration: O2 Expelled CO2
2. Most ozone (about 90%) is found in the stratosphere, which begins about 10–16 kilometers (6–10 miles) above Earth's surface and extends up to about 50 kilo- meters (31 miles) altitude. The stratospheric region with the highest ozone concentration is commonly known as the “ozone layer”

A student wanted to see if covering a leaf in foil would stop it from producing starch. Why should the student put the plant in a dark cupboard for 48 hours before returning it to the light and starting the experiment?
1. To make the results reliable
2. So that the plant would photosynthesise faster when returned to the light
3. So that any starch already in the leaf was used up by the plant
4. He did that simply
Answer:
4.) He did that simply
Explanation:
I'm just guessing it's 1 because the other answers don't seem reasonable
Answer:
Putting the plant in dark for 48 hours would stop the process of photosynthesis as light is required for it. Photosynthesis produces organic sugars which are stored in form of starch in plants. The absence of photosynthesis would lead to the consumption of all stored starch making the leaf starchless. The correct answer is option D.
