Answer:
However, some helium atoms have more or less than two neutrons. Atoms with the same number of protons but different numbers of neutrons are called isotopes. Because the number of neutrons can vary for a given element, the mass numbers of different atoms of an element may also vary.
During which phase of mitosis do the chromosomes pull away from the middle of the cell?
In Anaphase of mitosis chromosomes pull away from the middle of the cell.
During this period the replicated chromosomes are split and moved to the opposite poles of the cells.What is mitosis?It is the process by which cell replicates its chromosomes and then segregates them, producing two identical nuclei in preparation for cell division.
What are chromosomes?It is along DNA molecule with part or all of the genetic material of an organisms.

If an organism is heterozygous for a particular trait, the organism
A.
has the same allele on both chromosomes in a chromosome pair.
B.
is missing alleles on the chromosomes in a chromosome pair.
C.
has different alleles on the chromosomes in a chromosome pair.
D.
has extra alleles on both chromosomes in a chromosome pair.
Answer: C.
has different alleles on the chromosomes in a chromosome pair
Explanation:
Hetero means different.
A heterozygous condition is one in which the child inherits various eye-color genes from both biological parents. For that particular gene, a heterozygous genotype exists when there are two distinct versions. Thus, option C is correct.
What is the particular trait for heterozygous organism?When two distinct alleles of a gene (one mutant allele and one wild-type allele) are present in a diploid organism's cells, that organism is said to be heterozygous at that particular gene locus.
Heterozygosity describes a particular genotype, since the cell or organism is referred to be a heterozygote just for the particular allele in question.
The heterozygote may, however, occasionally have a phenotype that is somewhere between the phenotypes of both homozygous parents.
Therefore, has different alleles on the chromosomes in a chromosome pair.

Every cell contains DNA. The main purpose of DNA is to store the cell’s genetic information. How does DNA control the cell?
A. DNA activates nerve signals in the nervous system
B. DNA speeds up chemical reactions and lowers activation energy
C. DNA protects the cell from invaders.
D. DNA determines what proteins are made.
Answer:
The answer is D: DNA determines what proteins are made.
Explanation:
The nucleotide sequences that make up DNA are a “code” for the cell to make hundreds of different types of proteins; it is these proteins that function to control and regulate cell growth, division, communication with other cells and most other cellular functions.This process is called protein synthesis.All known cellular life and some viruses contain DNA. The main role of DNA in the cell is the long-term storage of information. It is often compared to a blueprint, since it contains the instructions to construct other components of the cell, such as proteins and RNA molecules.
Hope this helps!! ;)
DNA controls the cell by determining what protein are synthesized by the cell. Thus, the correct option is D.
What is Translation?Translation is the process of synthesis of proteins from the mRNA (messenger RNA) of the cell. This process occurs in the ribosome of the cell. In this process, the mRNA produced from the DNA encodes amino acids which join together to form large polypeptide and protein molecules.
mRNA are produced from DNA through the process of transcription. Transcription occurs in the nucleus of the cell. Through this process, DNA produces a sequence of mRNA which is complementary to it. This mRNA determines what proteins will be synthesized by the cell.
Therefore, the correct option is D.

Epinephrine enters the cell after it binds to the receptor. Yes, this statement is true.
What are the functions of epinephrine?
Adrenaline, also known as epinephrine, is a hormone and medication which is involved in regulating visceral functions. It appears as a white microcrystalline granule.
Epinephrine injection is used for emergency treatment of severe allergic reactions (including anaphylaxis) to insect bites or stings, medicines, foods, or other substances.
Through its action on alpha-1 receptors, epinephrine induces increased vascular smooth muscle contraction, pupillary dilator muscle contraction, and intestinal sphincter muscle contraction.

Anaerobes carry on whereas aerobes carry on cellular respiration
Answer:
Anaerobes carry on cellular respiration in the absence of oxygen, whereas aerobes carry on cellular respiration in the presence of oxygen.
Explanation:
Many of the cell processes needed need some energy to occur. Cellular respiration is the process by which cells degrade organic compounds and turn them into energy. Cellular respiration follows two ways, which depend on the presence or absence of oxygen, and both of them begin with the process of glycolysis, which occurs in the cytoplasm and does not need oxygen to occur.
Aerobic Respiration
Occurs in the presence of free oxygen.Series of reactions by which pyruvic acid (product of glycolysis) turns into CO₂ and H₂O, producing many ATP molecules. Respiration occurs in the mitochondria.Takes place in two steps or stages: Krebs cycle and electron transporter chain. Glycolysis and Krebs cycle produce electrons, which then travel along the electron transporter chain while releasing energy, and ATP is produced.Anaerobic Respiration
Occurs in the absence of free oxygenSeries of reactions by which using pyruvate (product of glycolysis) 2 ATP molecules van be produced. There are two ways in which anaerobic respiration can be produced: lactic fermentation and alcoholic fermentation. Lactic fermentation produces lactic acid and 2 ATPAlcoholic fermentation occurs in two steps, and the final products are ethylic alcohol, 2ATP, and 2 CO₂The whole anaerobic process occurs outside the mitochondria.plz help i need it i have to turn it in tomorrow
