A cell is placed into a solution and is left sitting for 24 hours. When you come back you notice the cell is exactly the same size it was beforehand. Which type of solution was the cell sitting in? Explain
Answer:
Isotonic Solution
Explanation:
There are commonly three types of solutions:
Hypertonic solution = the concentration of solute is greater than in the cellHypotonic solution = the concentration of solute is less than in the cellIsotonic solution= the concentration of solution and cell is same.So, if the cell was in any other solution, it would have been burst or it would shrink. but nothing changed because it was in a solution where outside environment is similar to the internal environment

Most nonrenewable energy resources are burned for us to use their energy. Which of the following is a nonrenewable energy source that is NOT burned?
A) nuclear
B) coal
C) natural gas
D) biofuels
Answer:
The correct answer is - A) nuclear.
Explanation:
Most of the non-renewable sources of energy are fossil fuels that are formed by the thermal decomposition of dead organic matter for million years and are converted to lighter hydrocarbons that contain high electrostatic potential energy.
Burning is the process that breaks the hydrocarbons into water vapor and CO2 with high amount of energy. Coal, natural gas and biofuels all three are fossil fuels and nuclear products are not fossil fuel but radioactive elements.

Why are silent mutations possible for some of the amino acids?
Answer:
That's possible because proteins are encoded by "triplets" of nucleotides, each responsible for adding a particular amino acid to the protein chain. A change in one nucleotide, however, doesn't always change the triplet's meaning; the mutated triplet may still add the same amino acid.

Describe an experiment used to prove that amino acids and sucrose go up and down the phloem.
Answer:
By using carbon-14 in the experiment in order to prove the statement.
Explanation:
Translocation occurs in the plant body in order to transport amino acids and sucrose from one part to another by the phloem tissues. In order to prove this, we have to incorporate radioactive element in the amino acid or sucrose which shows us that through which layer the amino acids and sucrose move in the plant body. For this purpose, carbon-14 can be used to trace the path of the translocation of amino acids and sucrose. Through this experiment we will find out that phloem layer is the path used by the plant to move amino acids and sucrose from one part to another.

what are the energy-storing compounds in photosynthesis?
Answer:
Hi, Plants store their energy in the form of starch, which is a complex carbohydrate that can be broken down into a simple carbohydrate (glucose) for the plant to use for energy. Plant cells store starch in storage organelles as all cells do. (vacuoles).
Answer:
Photosynthesis is the process by which organisms that contain the pigment chlorophyll convert light energy into chemical energy which can be stored in the molecular bonds of organic molecules (e.g., sugars). Photosynthesis powers almost all trophic chains and food webs on the Earth.
In pea plants, peas can be green or yellow in color. Assume that green peas are dominant to yellow peas. Is it possible for two plants with green peas to produce any offspring with yellow peas?
vocabulary words to use in response: dominant allele, recessive allele, , heterozygous, genotype, phenotype
Answer:
No.
Explanation:
Turns out they have yellow peas because the yellow version, Y, is dominant over the recessive green version, y. Y always wins out over y: When a pea plant makes seeds, only one of its two copies of the color gene goes into the seed. So if you have two green pea plants, each can only pass a green version.
Answer:
No.
Explanation:
Turns out they have yellow peas because the yellow version, Y, is dominant over the recessive green version, y. Y always wins out over y: When a pea plant makes seeds, only one of its two copies of the color gene goes into the seed. So if you have two green pea plants, each can only pass a green version.
If two-hybrid Ff rabbits mate, what will the offspring look like?
Answer:
25% FF - homogenous dominant
25% ff - homogeneous recessive
50% Ff - heterogenous
Explanation:
When two-hybrid Ff rabbits mate, then the offspring look like
25% FF - homogenous dominant25% ff - homogeneous recessive50% Ff - heterogenous.What is Mating?For the goal of sexual reproduction, opposite-sex or hermaphrodite organisms team together during mating. Two gametes join together during fertilisation. When two sexually reproducing creatures join their sex organs, internal fertilizations and insemination take place.
Punnett Square situations with two hybrid parents marrying are frequent. The heterozygous hybrid parents possess a single allele (A and a, Dominant and Recessive). There are four genotype outcomes that can happen if two hybrid parents mate.
Thus, when two-hybrid Ff rabbits mate, then the offspring look like

How do animals help recycle carbon atoms?
Answer:
animals, oxygen combines with food in the cells to produce energy for daily activity and then gives off carbon. The carbon combines with oxygen to form carbon dioxide (CO2) and is released back into the atmosphere as a waste product when animals breathe and exhale
