Mass increases at the crust.
B)
Less mass on the mountain causes uplift.
0
The crust beneath the mountain thins and rises.
D)
The mass of the crust decreases and the mass of the mantle increases.
Answer: It's A.
Explanation: I am doing UsatestPrep, Now I got this answer wrong, but afterwards it told me the right answer is! "Mass increases at the crust" I got the answer wrong originally because I chose B but it's actually A.
Answer:
Its A because Mass increases at the crust. . Mass is actually decreasing due to erosion of the crust, isostatic adjustment will thus, cause the mantle mass to increase over time.

Please help me with Q5 I’ll give brainliest!!!
Answer:
Ayo, your best answer would have to be B.
Explanation:
A student is investigating how substrate concentration affects the rate of anenzyme-catalyzed reaction. Which threevariables should be kept constant in the setup of thestudent’s investigation? Select all three variablesA. temperature of the reactionB. amount of enzymeC. amount of substrateD. amount of productE. pH of the reaction
Answer:
A. temperature of the reaction
B. amount of enzyme
E. pH of the reaction
Explanation:
Temperature should be kept constant because enzymes operate at different activity rates depending on the temperature. The same goes for the pH as well with different enzymes having different optimal pH levels.
The amount of enzyme should be kept constant as well because different concentrations of enzymes can determine how fast the reaction will occur.
Essentially anything that could affect enzyme activity apart from substrate concentration should be kept constant.

How do increases in the carrying capacity of Earth for people affect the carrying capacity of Earth for other species?
1. It increases for all species .
2. It decreases for all species .
3. It increases for most species
4. It decreases for most species .
Answer:
It decreases capacity for other species
Explanation:
As humans clear and develop more and more land, the animals that live in the cleared land lose their homes, so they have nowhere to live. This decreases the animals carrying capacity while increasing humans carrying capacity.
4. Take a beaker (jar or jug) with some water and put some drops of red or blue
ink in it. Take a tender twig of any flowery plant with leaves and flowers, preferably
white flowers, and put it in the beaker for 6 to 8 hours. What do you observe? For
further examination cut across its stem and look for the presence of colored water.
Explain your observations.
Answer:
Blue Ink patches are observed on the leaves of the plant. Also, on cutting across the stem of the plant, the red color of the solution is found along the length of the stem.
The above observation shows that the stem of the plant conducts water through its length to the leaves of the plant.
Explanation:
The leaves of plant obtain water and minerals from the soil through the roots of the plant. The water is conducted by the stem of the plant from the roots to the leaves of the plant where they are needed for photosynthesis as well as for cooling the plant. The xylem tissue in plants is responsible for conducting water to the leaves of the plant from the roots of the plant through the stem.
The conduction of water from the roots to the leaves of the plant is maintained by capillary action as well as by transpiration pull. Transpiration pull refers to the pull of water by the transpiration action taking place in the leaves of the pant, whereby water evaporates from the leaves of the plant through the opening in the leaf of the plant.
When the blue ink is added to the water, the colored water is conducted through the stem of the plant to the leaves. On getting to the leaves, the water molecules evaporate leaving behind the colored patches fond on the leaves. When the stem of the plant is cut, the blue color is seen along its length showing that the colored water was conducted through it.

Mesocarp
Explanation:
One nucleotide in a DNA strand is replaced with another, but the change results in
the same amino acid to be placed next in the protein. What is this type of mutation?
nonsense
point
silent
frameshift
Answer:
The type of mutation that occurs when one nucleotide in the DNA strand is replaced by another, but the change results in the same amino acid to be placed next in the protein is a silent mutation.
Explanation:
Silent mutations are molecular mutations where, despite a change in one of the DNA nucleotides, this change has no impact on the amino acid sequence that a synthesized protein will have.
An example of a silent mutation is the change in a DNA sequence TTC where a thymine replaces the cytosine, obtaining the TTT sequence:
Normal With mutation
DNA TTC TTT
mRNA AAG AAA
Amino Acid Lys Lys
There was a nucleotide change in the DNA, but the encoded amino acid was the same, which is a silent mutation that does not affect the amino acid sequence of a protein, its structure or function.
Drag the inputs and outputs of cellular respiration to their correct
place.
Answer:
Inputs are: Glucose
Output are; carbon dioxide, ATP and heat
Explanation:
Cellular respiration is the metabolic process by which cells of living organisms breakdown glucose molecules to release energy (ATP). Cellular respiration, which is a must for every living organism uses oxygen (aerobic) to break down glucose (C6H12O6) into carbon dioxide (CO2) and water (H2O).
Based on the question asked, the inputs of cellular respiration are GLUCOSE AND OXYGEN while the outputs are CO2, H2O, ATP and HEAT give out. The general chemical equation is as follows:
C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP
How does DNA determine an organism’s traits
Answer:
Traits are determined by genes. A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins.
in monohybrid cross between a pure breed plant that produces blue flowers (BB)and a pure breed plant that produces white flowers.The f1 generation produces only blue flowers. By means of a labelled cross diagram,state the type of flower you will expect if the f1 generation is self pollinated
Answer: If the F1 generation is self-pollinated, 75% of the flowers will be blue, while 25% will be white.
Explanation:
Monohybrid cross between blue and white: BB x bbThe cross produces 100% Bb --> blue is dominant, so all the flowers will be blue. This is the F1 generation.If F1 is self-pollinated, it will be Bb x Bb.The cross will produce 25% BB, 50% Bb, and 25% bb.Since blue is dominant, 75% of the flowers will be blue, while 25% will be white.Pictures:
The first picture is the BB x bb cross.The second picture is the Bb x Bb cross.I don't know why the pictures are appearing sideways. If you click the rotate button at the top right of the pictures, you can turn them.PLS HELP how does gene knockout work?

After this, rRNA creates bonds between _____________ to make __________
Answer:
After this, rRNA creates bonds between amino acids to make proteins.
Some important points to know:
rRNA (Ribosomal RNA) is used in the synthesis of proteins.
Amino acids are the building blocks of proteins which means that proteins are made up of amino acids.
When amino acids are joined together, they form proteins.
The bond between two or more amino acids when bonded is called "peptide bond".

Explanation:
Do environmental or genetic factors affect growth of organisms most?
Answer:
Examples of local environmental conditions could include availability of food, light, space, and water. Examples of genetic factors could include large breed cattle and species of grass affecting growth of organisms. The environment in which an organism lives plays an important role in modifying the rate and extent of growth. Environmental factors may be either physical (e.g., temperature, radiant energy, and atmospheric pressure) or chemical. Organisms and the cells of which they are composed are extremely sensitive to temperature changes; as the temperature decreases, the biochemical reactions necessary for life occur more slowly. A lowering of the temperature by 10° C (18° F) slows metabolism at least twofold and often more.
I copied this stuff from a bunch of different biology websites. It doesn't answer your exact question but I would have to say based on what I typed here it would be the environment that affects the growth of an organism more.
