would see?
Answer:I need some points,, I hope y’all can understand
Explanation:
The growth of bacteria can be observed as the bacteria grows very rapidly and fast by the process of asexual reproduction. They continuously multiplied and in very short period of time they divided from one to thousands.
What is asexual reproduction?Asexual reproduction is defined as the process of reproduction in which only a single parent is involved. Reproduction has been defined as the process carried out by the living organisms and during the process of reproduction the living organisms produces their own young ones and feed them. Reproduction is the supreme quality of living things.
There are two types of reproduction and these are sexual and asexual reproduction. The process of reproduction in which two parents are involved is said to be sexual mode of reproduction and the process of reproduction in which only single parent is involved in known as asexual mode of reproduction. The example of asexual reproduction are budding, fragmentation, spore formation, and binary fission.
Therefore, The growth of bacteria can be observed as the bacteria grows very rapidly and fast by the process of asexual reproduction. They continuously multiplied and in very short period of time they divided from one to thousands.

Radish flowers may be red, purple, or white. A cross between a red-flowered plant and a white-flowered plant yields all-purple offspring. The part of the radish we eat may be oval or long, with long being dominant. If true breeding red, long radishes are crossed with true breeding white, oval radishes, what will the offspring look like?
Answer:
The offspring will be purple and long
Explanation:
Radish flowers = Red, purple, or yellow
For a cross between a red-flowered plant and a white-flowered plant to yield all-purple offspring, that means either the red or white is dominant and the other recessive.
When cross it will result in 16 progenies.

4) Cell C suddenly lost all its dynamin proteins. Which of the following will most likely happen
right
away as a result of this loss?
A) Transcription factor X will no longer be able to go to the nucleus
B) A vesicle bud will no longer be pinched off from a membrane
C) A vesicle will no longer be tethered to a target membrane
D) A protein will no longer be targeted to the mitochondrial matrix
E) Two of the above
Answer:
B) A vesicle bud will no longer be pinched off from a membrane
Explanation:
Dynamin is a protein responsible for endocytosis, the process where the cell takes substances in from outside the cell through a system of vesicles. At the edge of the cell, the membrane pinches in to form a vesicle, which buds off from the membrane and enters the cell.
The step of this process that dynamin is involved in is in cleaving newly formed vesicles from the membrane. Without it, a vesicle bud will no longer be pinched off from a membrane
How does the water on earth regulate the earth temperature
Answer:
It absorbs a lot of the sun’s energy.
Explanation:
A large portion of the sun’s energy and heat is absorbed by the oceans, which causes water to evaporate. Water has a high heat capacity, and therefore absorbs a large portion of the sun’s heat, regulating the earth’s temperature.

A. Proteins
B. Carbohydrates
C. Lipids
D. Nucleic acids
Answer:
proteins create enzymes which speed up reaction
Enzymes are the molecules that catalyze biological reactions, while a catalyst is a material that aids in the occurrence of a chemical reaction, hence option A is correct.
How do enzymes catalyze chemical reactions?The crucial function of decreasing the activation energy of chemical events inside the cell is carried out by the majority of enzymes, which are proteins.
Enzymes are biological catalysts that significantly speed up reaction rates and have the propensity to be particular about particular reactants and products, a substrate is a term for the reactant in an enzyme-catalyzed process.
Proteins are called enzymes to catalyze biological reactions that would not occur without them. For chemical reactions like digestion and cellular metabolism, these enzymes are necessary.
Therefore, since enzymes are a specific type of protein that catalyzes chemical events inside cells, they are excellent therapeutic targets, hence option A is correct.

APT and photovoltaic cells are simikar because
The question is incomplete, below is the complete question.
ATP and photovoltaic cells are similar because
A. they are both key components of plant cells.
B. they both produce chemical and electrical energy.
C. they are both key components of solar panels.
D. they both use energy from the sun to separate electrons from atoms.
The correct answer to the question is option D
ATP and photovoltaic cells are similar because THEY BOTH USE ENERGY FROM THE SUN TO SEPERATE ELECTIONS FROM ATOMS.
Photovoltaic cells are otherwise known as solar cells,they are made of silicone that are specially treated,these specially treated silicon transfers solar energy gotten from the sun to electrical energy.
These solar powered photovoltaic panels converts the rays from the sun into electricity.this it does by exciting electrons found in silicon cells and also using the photons of light from the sun.
When this electricity is generated,it can be used to supply energy that is renewable to ones home or business.
In ATP, during the process of photosynthesis, sunlight penetrates the cell and further pass into the chloroplast. This light energy is further intercepted by granal stacks containing chlorophyll molecules, from then,some of those light energy are concerted to chemical energy,as this is going on,a phosphate is then added to a molecule to give rise to ATP.

Which of the following is not a step in the process of natural selection
A. Individuals who have favorable traits survive and reproduce more than those individuals lacking such traits.
B. Members of a population possess heritable variations.
C. People select which individuals breed and which ones do not.
D. Over multiple generations of reproducing, a larger proportion of the population will have those favorable traits and thus adaptation has occurred.
F. The population produces more offspring than the environment can support.
Answer:
A step that is not part of natural selection is people select which individuals breed and which ones do not.
Explanation:
Natural selection is a process in which favorable or unfavorable environmental conditions determine the evolution of species, producing differences in their genotype over a long period of time.
As its name indicates, it is a natural selection, in which no intervention by people is contemplated, so that people cannot determine which individuals breed.
Natural selection implies that the characteristics on which the environment influences are inheritable, that there is genetic variability in the population and that the variability of these characteristics implies the ease of reproduction and survival capacity.
The other options do form part of natural selection, since they are based on the three premises of this process:
Inheritable characteristics. Genetic variability. The variability of characteristics influences reproduction and survival.Photosynthesis/CR definition
Answer:
Photosynthesis is the process in which green plants and some other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
Cellular Respiration is the process through which cells convert sugars into energy. To create ATP and other forms of energy to power cellular reactions, cells require fuel and an electron acceptor which drives the chemical process of turning energy into a useable form.
