Answer:
When there is a mutation in the DNA nucleotide sequence where GGC passes into GGA, the mutation is a point mutation of the silent type.
Explanation:
A point mutation of DNA, where the cytosine nucleotide is changed to adenine, GGC to GGA, the resulting triplet mRNA is CCU, instead of GCC.
Codons CCG and CCU encode the same amino acid, which is proline (Pro), so despite the existence of a mutation, the protein that is synthesized will not have alterations in its number or sequence of amino acids.
Silent mutations are characterized by changes in a nucleotide in the DNA base sequence that do not affect changes in the coding protein, as happens in the change of GGC to GGA.

Elements are _____.
only found on earth
subatomic particles with a positive charge
substances that are made up of only one type of atom
a chemical substance composed of atoms of two or more different types of atoms
Answer:
C
Explanation:
An element is a material that consists of a single type of atom. Each atom type contains the same number of protons. Chemical bonds link elements together to form more complex molecules called compounds. A compound consists of two or more types of elements held together by covalent or ionic bonds.
For each of the following statements, indicate whether the statement describes the P generation, F1 generation, or F2 generation.
The plants in the
were allowed to self-pollinate.
The plants in the
are true breeding.
After a cross, there are three times as many tall plants as there are short plants in the
.
Answer:
The plants that were allowed to self pollinate were the First filial generation, filial, Latin for family. Or just the F1 generation plants.
The plants that are true breeding are Parental generation or for shorthand, the P generation plants.
The plants where there were three times as many tall plants as short plants are in the second filial generation, or the F2 generation.
This question is based on the Mendel’s Experiment.
Sir Gregor Johann Mendel.
Mendel experimented on pea plants and gave the laws for genetics which are a very important aspect of hereditary. Because of his experiment the terms recessive and dominant came into light and how the genes are passed from generations were also studied.
The statements can be completed as:
Plants that were allowed to self pollinate were F1 or the first filial generation.The true-breeding plants are P (parental) generation.The plants having the phenotypic ratio of 3:1 for tallness and shortness are in F2(second filial) generation.The steps can be explained as:
The cross which is the first step between the given alleles of a trait in a cross is called parental (P) generation.The progenies produced as a result of a cross between the parental traits is called the first filial (F1) generation.When the traits from the F1 is interbred then a second filial generation (F2) is produced.To learn more about parental and filial generations follow the link:

What is the difference between food chains and food webs? Food webs show the flow of energy from producers to consumers, and food chains show the flow of energy from consumers to producers. Food chains show a single path of energy in an ecosystem, and food webs show overlapping pathways of energy in that ecosystem. About ten percent of the energy is passed on to the next trophic level in food webs, but in food chains, about ninety percent is passed on to the next trophic level. Heat is lost when energy is passed on to the next trophic level in food chains, but in food webs, heat is not lost when energy is passed on to the next trophic level.
Answer:
Food chains show a single path of energy in an ecosystem, and food webs show overlapping pathways of energy in that ecosystem.
Explanation:
Unlike food chains, food webs show more detailed information about the different animals in an ecosystem and show multiple energy transfers to different animals from the same sources.
By looking at these examples, you will notice a dramatic difference in detail:
Food chains show a single path of energy in an ecosystem, and food webs show overlapping pathways of energy in that ecosystem.
What is food chain?Food chain shows the relationship between organisms by the food they eat.
What is food web?A food web is the natural interconnection of food chains and a graphical representation of what-eats-what in an ecological community.
Difference between food chain and food webFood webs show interconnection of food chains about the different animals in an ecosystem and different energy transfer processes.
Thus, food chains show a single path of energy in an ecosystem, and food webs show overlapping pathways of energy in that ecosystem.

Which statement correctly describes the number of chromosomes in body cells and gametes?
Answer:
its A
Explanation:
Body cells and gametes are both diploid correctly describes the number of chromosomes in body cells and gametes.
What are chromosomes?A chromosome is a long DNA molecule with part or all of the genetic material of an organism. In most chromosomes the very long thin DNA fibers are coated with packaging proteins; in eukaryotic cells the most important of these proteins are the histones.
Chromosomes are threadlike structures made of protein and a single molecule of DNA that serve to carry the genomic information from cell to cell. In plants and animals (including humans), chromosomes reside in the nucleus of cells.
One molecule of DNA and one protein make up one chromosome. Chromosomes are different sizes, and proteins called histones allow them to pack up small enough to fit in a nucleus.

Which of the following domains include prokaryotic organisms?
A. Archaea only
B. Eukarya only
C. Archaea and Bacteria
D. Bacteria only
C. Archaea and Bacteria
Archaea and Bacteria are categorized into the domains of prokaryotic organisms, hence option C is correct.
What are prokaryotic organisms?There are three domains of the life the Archaea, the Bacteria, and the Eukarya, in which Archaea and Bacteria belong to prokaryotic cells but eukaryotic cells belong to the Eukarya domain.
Prokaryotic organisms include the organism's absence of a nuclear membrane and not having well-defined cell organelle, this includes bacteria. It is a unicellular organism having an asexual mode of reproduction.
The Eukarya domain includes the eucaryotic cells having a true nuclear membrane, this domain includes all the eukaryote plants the human beings.
Therefore, Archaea and Bacteria is the correct option.

In homologous recombination in E. coli, the protein that moves along a double-stranded DNA, unwinding the strands ahead of it and degrading them, is:
Answer:
RecBCD enzyme
Explanation:
RecBCD is an enzyme of the E. coli bacterium that initiates recombinational repair from potentially lethal double strand breaks in DNA which may result from ionizing radiation, replication errors, endonuclease, oxidative damage, and a host of other factors. The RecBCD enzyme is both a helicase that unwinds, or separates the strands of DNA, and a nuclease that makes single-stranded nicks in DNA.
