Which best explains the genetic similarities between species? A. More closely related species will have identical dna B. More closely related species will have fewer dna similarities C. More closely related species will have more similarities in dna D. There is no link between the relationships of species and their dna
Answer:
C
Explanation:
The correct answer would be that more closely related species will have more similarities in DNA.
The DNA stores the genetic information of organisms and contains a set of instructions that defines how organisms look. It is usually used to delimit species with closely related species of organisms having similar DNA. The more related species are, the more similar their DNA would be and vice versa because the similarity in the DNA of organisms is often used as an indication of descending from a common ancestor.
The correct option is, therefore, C.
Genes are the hereditary unit of life, which carries the information from parent to daughter cells. The organisms belonging to the same species will have the same genetic sequence.
The correct answer is:
Option C. More closely related species will have more similarities in DNA
The DNA stores the genetic information of the organisms and codes for the traits of the organism.
The genes delimit the species' relativity of the organisms. The species that are closely related will have more similarities in the genetic sequence.
The similarity of the genes or DNA is often used as an indication of descending of species from a common ancestor.
Therefore, option C is correct.

does aerobic and anaerobic respiration have the same number of carbons, hydrogens and oxygens? Explain.
The fundamental difference between aerobic and anaerobic respiration is the usage of oxygen in the process of cellular respiration. Aerobic respiration, as the name suggests, is the process of producing the energy required by cells using oxygen. The by-product of this process produces carbon dioxide along with ATP – the energy currency of the cells. Anaerobic respiration is similar to aerobic respiration.
What is the source of the energy that
flows through most of the food chains on
Earth?
Answer:
the corret answer is the sun
Explanation:
The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers such as plants, algae, and cyanobacteria use the energy from sunlight to make organic matter from carbon dioxide and water.
Animal cells are eukaryotic and bacteria cells are prokaryotic. This is because?
Answer:because eukaryotic cells are multicellular and prokaryotes are unicellular.
Explanation: multicellular are more complex than unicellular
Which statement about DNA is NOT correct?
O DNA is found in the nucleus of eukaryotes
O DNA is single stranded
O Deoxyribose is the sugar in DNA
o there are two single ring nitrogen bases in DNA
Answer:
B (2nd Option): DNA is single-stranded
Explanation:
A is correct: DNA is indeed found in the nucleus of eukaryotes.
B is incorrect: Although there can be single strands of DNA (ssDNA), DNA is usually double-stranded which is how it forms its characteristic double-helix shape.
C is correct: Deoxyribose is indeed the sugar in DNA (Deoxyribonucleic Acid)
D is correct: The two single ringed nitrogenous bases in DNA are thymine and cytosine, while the other two (Adenine and Guanine are double ringed.

Osmosis does not require an additional input of energy from the cell.
Osmosis is considered to be a type of
active transport
endocytosis
passive transport
exocytosis
Answer:
Osmosis is considered to be a type of
active transport.
Explanation:
Answer:
passive transport
Explanation:
Osmosis is the process in which water molecules move from a region of higher water potential to a region of lower potential down a water potential gradient across a partially permeable membrane, so little energy is required to carry out this process, thus it is a form or passive transport.

isabella works for an environmental safety group. her group wants to answer the question “to what lengths must we go to protect plants and animals?” why is her groups research question flawed?
Answer:
In this case, the question asked is "To what lengths must we go to protect plants and animals?", which is not specific and cannot be used for scientific research.
The ecological researches for the safety of the environment involves the protection of the plants and the animals on the basis of their number and vulnerability to extinction. Almost all the length of the plants are ecologically important and can decrease in number due to the changes in the environment, the length is not a parameter to determine the protection boundary.

There are only 4 types of nucleotides in mRNA and 20 types of amino acids in proteins. This figure shows how 4 types of nucleotides can provide a unique code for each of the 20 types of amino acids.
6a. The mRNA code for each type of amino acid is a
sequence of _______ nucleotides, called a codon.
(2 / 3 / 4)
6b. In the figure, which mRNA codon codes for the amino acid Phe?
Answer:
The mRNA code for each type of amino acid is a sequence of three nucleotides, called a codon.mRNA codon that codes for the amino acid Phe es UUU.Explanation:
The messenger RNA (mRNA) has in its structure sequences of 4 nucleotides adenine, uracil, guanine and cytosine. The possible combinations of these nucleotides to group into triplets is 64 codons to form 20 amino acids, from which it can be concluded:
An amino acid can be encoded by more than one codon. From these combinations the three STOP codons are obtained.A mRNA codon is a sequence of three nucleotides that serves to encode an amino acid.
Phenylalanine (Phe), according to the image, is formed with the UUU codon.
