Answer:
Option A, B and D apply except C
Explanation:
All DNA contains the same four nitrogenous bases, A, T, C, G and these bases combine in threes to produce 20 amino acids which make proteins.
On the other hand, DNA is transcribed in the nucleus to mRNA transcript and then sent to the cytoplasm for translation. mRNA is then translated to proteins with the aid of the ribosomes. Thus making option C wrong.
Small fragments of orbiting bodies that have landed on Earth are known as meteorites. If the fragments are still orbiting earth are known as meteoroids. They are not called meteorites until they enter Earth's atmosphere. Once a meteor enters Earth's atmosphere it will begin to burn up. It may burn up completely or lose most of its size by the time is lands on Earth's surface.
Answer:
B
Explanation:
Adaptation can be described as a process that helps the organisms fit their environment and enhancing their evolutionary fitness (reproductive success). Adaptation makes organism become well-suited for an environment and thus, help them to survive and produce more offspring. Also, adaptation may refer to a phenotypic or adaptive trait with a functional role in the success of each organism in their habitat.
They increase the genetic diversity of the species
Answer:
A. Water enters a plant by passing through the root cell membranes.
Explanation:
Osmosis is a kind of passive transport i.e. no energy input is required by the cell, that involves the movement of water across a semi-permeable membrane from a region of low solute concentration/high solvent concentration to a region of high solute concentration/low solvent concentration. The movement is usually facilitated by a difference in concentration gradient between the cell's membrane and the extracellular solution.
In this question, water from the soil enters into the root's cell via its cell membrane, which acts as the semi-permeable membrane. This movement must have occured because the solute concentration in the root's cell is higher than that of the soil, forming an osmotic gradient.
Answer:
1) the independent variable would be the type of treatment so underline treatment 1 and 2. The dependent variable would be the seed Yield so circle where it says Seed Yield (g/m2)
2) Yes, the bacterial treatment did have for because based on the results, the seed yield increased when putting the treatment. You can tell that with treatment 2, it was the one that had a better effect.
Explanation:
