tRNA uses (anticodons/codons) to match to the mRNA.
Answer:
anticodons
Explanation:
codons are for mRNA
tRNA uses anticodons to match to the mRNA.
Which one does tRNA uses?tRNA (transfer RNA) molecules are responsible for carrying specific amino acids to the ribosomes during protein synthesis.
They have an anticodon region that consists of three nucleotides that are complementary to the codons on the mRNA (messenger RNA). The codons on the mRNA determine the sequence of amino acids in the growing polypeptide chain.
The anticodon on the tRNA base pairs with the complementary codon on the mRNA, ensuring that the correct amino acid is incorporated into the growing protein chain. The matching between the anticodon and codon is essential for the accurate translation of genetic information into protein synthesis.

What is the main difference between active transport and passive transport?
(A) During active transport the water inside the cell is used to transport substances throughout the cell. Passive transport uses the cell's cytoplasm to move substances around the cell.
(B) Passive transport moves substances throughout the cell without using the cell's energy and active transport moves substances using the cell's energy.
(C) Active transport moves substances from higher concentrations to lower concentrations and passive transport moves substances from lower concentrations to higher concentrations.
(D) Passive transport moves substances that are too large to get through the cell membrane by forming a vesicle inside the cell and active transport forms the vesicle on the outside of the cell.
Answer:

what is chemical weathering? what are some facts?
Answer:
Chemical weathering is the erosion or disintegration of rocks, building materials, etc., caused by chemical reactions (chiefly with water and substances dissolved in it) rather than by mechanical processes.
Explanation:
1. There are four types of chemical weathering: Reaction with water, Reaction with acid, Reaction with oxygen, and Reaction with organisms.
2. Chemical weathering occurs when water dissolves minerals in a rock, producing new compounds. This reaction is called hydrolysis. Hydrolysis occurs, for example, when water comes in contact with granite. Feldspar crystals inside the granite react chemically, forming clay minerals.
In rabbits, spotted coat (S) is dominant to solid color (s) and black (B) is dominant to brown (b). A true-breeding black spotted rabbit is mated to a true-breeding brown solid rabbit to produce a heterozygous F1 generation. Two F1 individuals are mated, and you do not see a 9:3:3:1 (black spotted: black solid: brown spotted: brown solid) ratio of offspring, but instead see that almost all offspring are a non-recombinant phenotype. This tells you that
Answer:
Epistasis effect result into these offspring
Explanation:
Given
spotted coat (S) is dominant to solid color (s) and black (B) is dominant to brown (b)
Genotype of true-breeding black spotted rabbit BBSS
Genotype of true-breeding brown solid rabbit bbss
Genotype of offspring BbSs
In normal crossing between BbSs and BbSs offspring of F1, should produce offspring in the ratio 9:3:3:1
But it does not happens in this case the simple reason could be presence of Epistasis in which the alleles assort independently but do not express themselves because of the following reasons -
a) Interaction between two or more loci thereby resulting into new phenotypes
b) An allele at one locus masks effects of other allele at one or more loci
c) Allele at one locus modifies the effects of alleles at one or more other loci
As a result of the experiment scientists did with Mexican tetras, it seems likely that their first hypothesis about blindness in the tetras is right. Explain how the result of the experiment supports their first hypothesis.
The scientists' first hypothesis is that blindness gives the fish some sort of evolutionary advantage, but not directly.
The experiment was: The scientists transplanted a lens from the eye of a surface tetra embryo into the eye of a cave tetra embryo. The result was striking—the surface tetra lens into the cave tetra caused all of the surrounding tissues to develop into a healthy eye.
A result that supports the hypothesis 'blindness gives the fish some evolutionary advantage, but not directly' may be a higher fitness in close relatives of fish.
What is a hypothesis?An scientific hypothesis is a given explanation to a scientific observation from the real world.
A hypothesis must be verifiable, which means that it can be confirmed or rejected by using the scientific method.
In conclusion, a result that supports the hypothesis 'blindness gives the fish some evolutionary advantage, but not directly' may be a higher fitness in close relatives of fish.

Analyze the effects of DNA mutations
on the
of an organism.
Answer:
DNA mutations or Chromosomal mutations are also called chromosomal aberrations, chromosomal abnormality, or chromosomal disorders, all indicating a possible alteration in the morphology and structure of the chromosome.
DNA mutations lead to abnormalities in the function of the cell and organism, as chromosomal or DNA mutations can result in abnormal gene numbers or positions.
These are known to cause different genetic diseases that can be hereditary and are transferred from one generation to another.
These mutations, however, do not always affect the functioning of the cell as some mutations might affect regions of chromosomes that do not make up the genetic makeup of the organism.
Even though gene mutations are usually more severe than chromosomal mutations, some chromosomal mutations might result in gene mutations.

Which statement best describes the movement of ocean waves? Water moves across the ocean's surface water remains in the same place as wave (energy) travels through it water moves because there is a difference in density of the water creating a wave none of these
Answer:
water remains in the same place as wave (energy) travels through it
Explanation:
Winds influence the ocean and its movements. Air current running on the ocean surface transfers energy to water. A wave is nothing else than energy. When the winds provide energy to the water surface and produce waves, it occurs a particular water molecules´ motion. They move in circles from up to down, up to a certain depth, and go back to the surface. And they do so while energy from the wave is passing through. Waves are the ones that move through the ocean until they reach the shore, where the energy is transferred to land. Water molecules remain in the same general area, while energy travels from molecule to molecule as a wave.

Write a 200-word report on your research, using proper grammar, correct spelling, and appropriate punctuation. Make sure you include:
A definition of overgrazing
A discussion on the damage overgrazing can cause
The advantages and disadvantages of each type of grazing
A discussion on the type of grazing you select to use, which includes your justification of why you selected the grazing strategy
Answer:
answer is in explanation before
Explanation:
Overgrazing occurs when plants are exposed to intensive grazing for extended periods of time, or without sufficient recovery periods. It can be caused by either livestock in poorly managed agricultural applications, game reserves, or nature reserves. Overgrazing combined with overstocking has the most damaging outcomes to the world’s natural environment. The scarcity of water resources, water pollution, degeneration of coral reefs, and eutrophication are all connected to overgrazing. The chief polluting elements include farm chemicals and animal wastes.
Types of grazing systems 1. Types of grazing systems Grazing animals (such as cattle, sheep and goats) feed on the leaves and shoots of grass... 2. Zerograzing In this type of grazing system, the animals are not allowed to go out into the pastureto graze.
Overgrazing is defined as the practice of allowing too many livestock to graze on a particular area of land for an extended period. This leads to a decrease in the vegetation cover and the soil's capacity to hold moisture, which results in soil erosion and desertification.
What is overgrazing?There are three types of grazing systems: continuous grazing, rotational grazing, and intensive grazing. Continuous grazing involves leaving livestock on a particular area of land throughout the year. Rotational grazing involves rotating livestock to different areas of land to prevent overgrazing. Intensive grazing involves keeping livestock in smaller paddocks and rotating them frequently.
Hence, overgrazing is defined as the practice of allowing too many livestock to graze on a particular area of land for an extended period. This leads to a decrease in the vegetation cover and the soil's capacity to hold moisture, which results in soil erosion and desertification.
