how does water move through the water cycle
Answer:
The water moves from one reservoir to another, such as from river to ocean, or from the ocean to the atmosphere, by the physical processes of evaporation, condensation, precipitation, infiltration, surface runoff, and subsurface flow. In doing so, the water goes through different forms: liquid, solid (ice) and vapor.

Transcription is the process that must happen in order to make
Answer:
a protein
Explanation:
Transcription is one of the three main, necessary events needed for proteins to form in a cell. This happens when DNA is transcribed to mRNA. Thymine (T) is subbed in by Uracil (U), so when transcribing, A's turn into U's, not T's.

what type of mutation has the least amount of impact on a protein ?
Answer: Silent Mutation
Explanation: Silent mutation: Some mutations that change DNA bases do not have any effect on the sequence of amino acids in the protein. These mutations are called silent mutations and they do not affect the structure or function of the protein because there is no effect on the amino acid sequence.
Answer:
Point Mutations
Explanation:
It is the least harmful mutation

What causes cells in living organisms to be different from one another?
O A An organism evolves new cell types in response to its environment
O B. The brain of an organism sends a signal to its cells to differentiate when the organismis in danger.
O c The DNA of an organism moves from one cell to another, allowing different cells to have different functions
O D. An organism expresses different genes at different times in development, causing cells to be specialized
Explanation:
The cell types in a multicellular organism become different from one another because they synthesize and accumulate different sets of RNA and protein molecules. They generally do this without altering the sequence of their DNA.

Which of the following best describes the genes of offspring of organisms that reproduce sexually?
Answer:
Each of the offspring is genetically unique and received some of its genetic
Explanation:
While reproducing sexually, The zygote receives half of the gametes of male organism while half of the gametes of female organism. This constitutes to the total number i.e. 46 chromosomes.
While the zygote receive half from male and half from female, This means that the offspring produced by the zygote will have both the characteristics in common of the male as well as female. Remember that, Chromosomes contain gene which are particularly responsible for characteristics.
So, Each of the offspring is genetically unique and received some of its genetic information from each parent, so each has some traits in common with each parent.
which organ is part of the body system that transports nutrients from food through the entire body
Answer:
The Circulatory System
Explanation:
imagine what happens if materials are not send out of the body from time to time ?
Explanation:
excretory system is present in human body which discharge out the waste material time to time. basically when a cell in a body breaks down they produce various waste material like carbohydrates eliminates carbon dioxide while digestive system eliminates through feces. any malfunctioning can cause serious problem like constipitation kidney failure and kidney stones

In what ways are the features of a plant living in water different from a plant living on land ?
Answer:
Earth, both on land and in water. Wherever they
live, plants provide food and oxygen to the
creatures that live nearby – including humans!
In this activity we will examine both a
terrestrial (land) plant and an aquatic (water)
plant. They have many things in common, but the
ways they get air, food and water change along
with the environments in which they live.

Answer:
You gotta sketch out a sperm egg under the questions after the example.
Explanation:
You see, there is an example, right? Well, then, depending on how many chromosomes there are, write the correct chromosome number in each cell. Number 1 is just an example of what you gotta do. Mosquito wing cell contains 6 chromosomes. The cell contains at least 42 chromosomes. Do what you saw in the example: egg cell gamete + cell gamete = 1st somatic cell.

What does it mean to be in the same species
Answer:
organisms belong to the same species if they can interbreed to produce viable, fertile offspring. Species are separated from one another by prezygotic and postzygotic barriers, which prevent mating or the production of viable, fertile offspring.
plz help asap! The activity of many cellular enzymes is regulated by activators and inhibitors. Enzyme activity is also regulated in eukaryotic cells by which of the following mechanisms?
Compartmentalization and restricting enzymes to specific organelles or membranes
Secreting enzymes out of the cell
Limiting the availability of substrates
Changing the primary structure of enzymes
Answer:
compartmentalization and restricting enzymes to specific organelles or membranes
Cellular steroid gradients are produced by the compartmentalization of enzymes into various organelles of a cell, and this might impact how well the various steroid products are balanced. Thus, option A is correct.
What is Compartmentalization?In biology, the biomembrane, or biological membrane, effectively compartmentalizes enzymes by allowing them to perform only certain functions within a limited area.
The enzymes may be located on the membrane surface or inside the defined compartments.
A percentage of the enzymes would likely not work or their ability to catalyze reactions would likely be insufficient if there was just one cellular compartment.
This is because enzymes catalyzing distinct reactions frequently have variable temperature and pH optimums.
Therefore, Compartmentalization and restricting enzymes to specific organelles or membranes.
