Answer:
The correct answer would be - D. the distribution of alleles in a population.
Explanation:
Allele frequency in population genetics is the term used to provide the amount of the different alleles in particular loci. In other words, it is the distribution of alleles in a population.
The term allele frequency refers to the fraction of the copies of the gene of the alleles in a known population. It can be calculated by the number of allele present of interest divided by total number of alleles in a population.

Answers
Answer:
A. Uses the law of superposition to determine which rock is older or younger.
Explanation:
I majored in Biology
The law of superposition of rocks is used to determine the age of rocks.
A rock is defined as a solid mass of minerals which could be found above or below the earth's surface. Rocks are of different types and they take different forms.
In order to determine the relative age of rocks, the law of superposition is used. This law can be used to determine which rock is older or younger.

From which molecules are mRNA molecules transcribed?
A. tRNA
B. rRNA
C. DNA
D. protein
Answers
Answer:
C
Explanation:
mRNA molecules are transcribed from DNA molecules. Therefore, option (C) is correct.
Synthesis of mRNA molecules utilising a DNA template occurs during transcription. RNA polymerase and other transcription factors attach to particular sections of DNA known as promoters in the nucleus of eukaryotic cells. The DNA double helix is subsequently unwound by the RNA polymerase, and using one of the DNA strands as a template, it starts to synthesise a complementary RNA strand.
According to the complementary base pairing principles, the RNA polymerase adds nucleotides to the expanding mRNA strand during transcription. While cytosine (C) pairs with guanine (G), adenine (A) in DNA pairs with uracil (U) in mRNA. The mRNA molecule is released and the DNA double helix reforms once the full gene sequence has been read.

Free lime and natural gypsum, in addition to soluble salts, are frequently found in the C horizon. Therefore, option (C) is correct.
What is C Horizon?Free lime and natural gypsum, in addition to soluble salts, are frequently found in the C horizon. Unconsolidated material can be found above bedrock at the C Horizon, which is also referred to as the substratum. It has not undergone enough deterioration to be classified as soil, but it is nevertheless considered to be a layer of a soil profile.
The C horizon is often composed of boulders, cobbles, pebbles, and other types of rocks that have not been worn or have only been lightly weathered. Due to the fact that the layers of soil that are found above the C horizon are typically generated from this material, these rocks are referred to as parent rocks.

Answers
Answer:
a quick burial
The most important part: the body has to be buried suddenly, which is rare. Rapid burial can happen due to natural effects, including volcanic eruptions, which bury things in ash, or dying near a flooding stream, which rapidly covers the body in sediment.
Explanation:
Water seeps into the remains, and minerals dissolved in the water seep into the spaces within the remains, where they form crystals. These crystallized minerals cause the remains to harden along with the encasing sedimentary rock.

A dinner a marathon runner would eat the night before running the Boston Marathon would be rice and chicken. Rice has a simple carbohydrate and will build up the ATP in his system to make his run time better and give him energy. Chicken has a long term energy source that will keep him full and his muscles working throughout the marathon.
What is carbohydrate?Carbohydrates has been defied as the contains biomolecule that contains all the carbon hydrogen and oxygen in a same ratio of 2:1. Carbohydrates are main source of the energy of the body they work as the fuel for the brain, kidneys central nervous system and heart muscle.

Gradual speciation is more likely to be associated with small changes building up in:___________
A. ability to reproduce asexually
B. genes associated with DNA synthesis
C. geographically diverse areas
D. stable environments
Answers
Answer:
D. stable environments
Explanation:
In the gradual speciation model, changes in species are slow over time that occur in small steps. Change in speciation rate influences two factors that are environmental conditions and population size.
Gradual speciation mostly occur in large populations that move towards evolution and live in a stable environment. The stable environment provides enough time for the evolution to happen and stable habitat for the new species to grow slowly.
Hence, the correct answer is "D. stable environments".

Answers
Answer:
C. Oxygen supply
Explanation:
Autotrophs make their own food with carbon dioxide and create oxygen as a byproduct. Heterotrophs need oxygen to create energy and create carbon dioxide as a byproduct. Therefore, if there are no autotrophs, the carbon dioxide in the air won’t be able to be used to turn to oxygen, which heterotrophs need. The heterotrophs will use up all of the oxygen in the air, leaving lots of carbon dioxide behind. This is why we need plants and trees! Thus, the answer is C.

If the objective lenses of a microscope can be changed without losing focus on the specimen, they are said to be ______. A) equifocal. B) totifocal. C) parfocal.D) optifocal.

Answer:
C) parfocal.
Explanation:
A microscope can be defined as an optical device that is typically used to make an enlarged (magnified) image of a minute (small) object and as such reveals all the little information about the object that cannot be seen by the natural human eye.
A microscope is said to be parfocal if its lense is binocular and they can both be in focus.
Hence, if the objective lenses of a microscope can be changed without losing focus on the specimen, they are said to be parfocal.
