A scientist uses radioactive nitrogen to label the nitrogenous bases of the DNA of a cell. Then the DNA is allowed to replicate, and the new strands take up non-radioactive bases. Do one, both, or neither of the daughter cells have radioactive DNA? Explain.
I think yes, because from what i knew. When the DNA replicate, it will be same as the original/mother DNA. so it will both have radioactive DNA.
Just think, if only one DNA have radioactive then it wont be dangerous, but it affect the replication DNA, then its different case and will be dangerous for the body. You must've heard that radioactive can be dangerous for the body.
Sorry if im wrong
Answer:
I would say one..
Explanation:
It says the new strands take u non-radioactive bases.. if he only used the radioactive to label one of them then I would say one..

How can the type of bedrock under soil affect the characteristics of the soil? *
by absorbing water
by making the soil more fertile
by weathering and becoming new parent material
by providing surface area for nutrient accumulation
Answer:
by weathering and becoming new parent material
Explanation:
Soil formation occurs as a result of the the decay or the remains of plants and animals which are used up.
Weathering can be defined as the physical and chemical breakdown of rock into smaller pieces called sediment. Weathering can be classified into two categories namely;
I. Physical weathering : it is the process of breaking rocks into pieces without affecting its chemical composition e.g temperature, abrasion and frost action.
II. Chemical weathering : it is the process of breaking rocks into pieces by chemical action which leads to changes in its chemical composition e.g carbonation, hydration, plant acid and oxidation.
Hence, the type of bedrock under a soil affect the characteristics of the soil by weathering and becoming new parent material i.e the contribution of small rock particle to the soil.
Why are normally unseen members of the food web, such as soil microorganisms, essential to the nitrogen cycle?
Answer: Why are normally unseen members of the food web, such as soil microorganisms, essential to the nitrogen cycle? ... Since not all organisms can utilize the nitrogen gas directly, these microorganisms convert nitrogen in different nitrogen compounds, such as ammonia, nitrites, and nitrates. In this article we explore how nitrogen is cycled and the important role of microbes in this cycle. ... Nitrogen is required by all living organisms for the synthesis of organic molecules such as amino acids, nucleic acids and proteins. The Earth's atmosphere contains almost 80% nitrogen gas
Bacteria play a central role:
Nitrogen-fixing bacteria, which convert atmospheric nitrogen to nitrates.
Bacteria of decay, which convert decaying nitrogen waste to ammonia.
Nitrifying bacteria, which convert ammonia to nitrates/nitrites.
Denitrifying bacteria, which convert nitrates to nitrogen gas.

Explain the difference between sex hormones and glandular stimulating hormones
Answer:
Sex hormones are those hormones that within the endocrine system of the human being, are considered more directly involved in human sexuality, particularly in the processes of copulation and reproduction.On the other hand, glandular stimulating hormones are those that act on hormonal production in another endocrine gland, that is, they are stimulants, since they stimulate the corresponding glands.
Explanation:
Sex hormones are chemical substances secreted by the sex endocrine glands (the testes and ovaries) and subsequently released into the bloodstream, to be transported to the organs on which they exert their action (increasing or decreasing their activity).The production of hormones is regulated in many cases by a negative feedback system, which causes an excess of a hormone to be followed by a decrease in its production. The glandular stimulating hormones are transported to the blood to stimulate the corresponding glands (thyroid, adrenal cortex, and gonads) and these will be the ones that secrete various types of hormones (thyroxine, corticosteroids and sex hormones, respectively), which in addition to acting in the body, they feed back into the pituitary and hypothalamus to inhibit their activity and balance the respective secretions of these two organs and the target gland. For example, follicle-stimulating hormone encourages sperm production in men and stimulates the ovaries to release eggs in women. Luteinizing hormone and follicle stimulator work together to allow normal function of the ovaries or testicles.

What kind of mutation would occur if a sequence of DNA is changed from ATCGGCTTAACG to ATCGGCTAAACG?
Answer:
Base substitution mutation
Explanation:
Mutation is the alteration or change that occurs to the sequence of a gene caused by a mutagen (chemicals) or spontaneously-induced. Depending on how the mutation occurs, it is of different types. The mutation shown in this question is as follows:
ATCGGCTTAACG to ATCGGCTAAACG
This type of mutation is called SUBSTITUTION MUTATION. Substitution mutation is a type of mutation that involves the replacement of one or more nucleotide base by another. In this original sequence; ATCGGCTTAACG, the eight base T was replaced by base A in the sequence, hence, it is a substitution mutation.
In some bunnies, the gene for fur color is controlled by condominance. The allele for gray color is G and the allele white color is W. The heterozygous phenotype results in a gray and white bunny/ What is the genotype for gray bunnies? what is the genotype for white bunnies? what is the genotype for gray and white bunnies?
Answer:
Genotype gray bunnies: GG
Genotype white bunnies: WW
Genotype gray and white bunnies: GW
Explanation:
In diploid species (2n), organisms receive one gene copy (allele) from each parent. Codominance is a relationship that occurs when both alleles of the same gene show dominance. In consequence, the expression of both alleles in heterozygous individuals results in a new phenotype. In this example, the expression of G and W alleles results in a gray and white phenotype. Examples of codominance include individuals with type AB blood group in humans or the roan coat color in horses.

Answer:
Required answer in the attachment18) What kind of mutation causes extensive damage in the DNA?
a. Point mutation c. Frame shift mutation b. Chromosomal mutation d.Nonsense mutation
Answer:
c. Frame shift mutation.
Explanation:
Frame shift mutation is a type of mutation which causes more damage to the DNA of the cell. It causes changes in the amino acid sequences in a polypeptide chain. Point mutation is a type of mutation in which only one amino acid changed, while on the other hand, frameshift mutation changes the whole sequence of amino acids so we can say that frame shift mutation is more damaging to the DNA molecule.

Answer:
RESPUESTA:OPCION B espero te ayude
A accomplish this task, and muscle C does the opposite of A, then muscle A is a antagonist to prime mover.
What is antagonist muscle?muscles can only pull. They typically work a joint in pairs because of this. When a body part is moved, one of the pair's muscles contracts; when the body part is brought back to its starting position, the other muscle in the pair contracts.
Antagonizing pairs of muscles are those that function in this way. When two muscles are antagonistic, one contracts while the other relaxes or lengthens. The muscle that is lengthening or relaxing is referred to as the antagonist, while the muscle that is contracting is referred to as the agonist.
Therefore, A accomplish this task, and muscle C does the opposite of A, then muscle A is a antagonist to prime mover.

The number of neurotransmitter molecules located within a specific synaptic gap would most clearly be
reduced by
Answer:
The correct answer is - reuptake.
Explanation:
The process that reabsorbs the neurotransmitters known as reuptake which reduced the number of neurotransmitter molecules. Neurotransmitter transporter found on the outer membrane of the plasma membrane assists the process of reuptake by reabsorbing the neurotransmitter molecules from the specific synaptic gap. Neurotransmitters recycle by this process in order to reuse again after a time for the particular signal to last.
Thus, the correct answer is - reuptake.
