Hope this helps!!!
a. The question the students were trying to answer was "Which type of soil would rose bushes grow the tallest in?" Their hypothesis was that one type of soil would lead to the rose bushes growing taller than the others.
b. The independent variable in this experiment was the type of soil in which the rose bushes were planted. The dependent variable was the height of the rose bushes. They likely measured the height of the bushes at regular intervals (e.g. daily or weekly) using a ruler or tape measure.
The conditions (variables) that were controlled during the experiment were the size of the rose bushes, the size of the pots, the amount of water, the light and temperature conditions.
What is a variable?A variable is a characteristic or property that can take on different values or can be manipulated in an experiment or study. In science, variables are used to help understand the relationship between different factors or phenomena.
They can be classified as independent variables, which are manipulated by the experimenter, and dependent variables, which are observed or measured as a result of the manipulation of the independent variable. In some cases, there are also controlled variables which are kept constant in an experiment

Demand of oxygen in water does not increase with increase in
a/concentration of solid waste
b/number of aquatic plants
c/number of aquatic animals
d/rapid flow of water
Answer:
b. number of aquatic plants
Explanation:
The number of aquatic plants doesn't increase the demand for oxygen in water because these plants take in carbon dioxide rather than oxygen. This means that an increase in their number will not trigger an increase demand for oxygen, rather it will trigger an increase demand for carbon dioxide in its dissolved form.
An increase in the concentration of solid waste, increases the demand for oxygen because it is needed for decomposition.
An increase in aquatic animals will increase the demand for oxygen in its dissolved form because aquatic animals take in oxygen to survive.
An increase in the flow of water increases the demand for oxygen because as water flows, it mixes with air. The more rapid it is, the higher the chance to mix with oxygen.

Low pitched male voices (RR) and a high pitched male voice (rr). Heterozygotes have a baritone voice. This is an example of _________
Answer: incomplete dominance
Explanation:
Incomplete dominance is also referred to as partial dominance or semi dominance. It occurs when the two forms of gene in a trait combine in such a way that one does not have a dominance over the other one. Therefore, there's a blend of both genes in the physical appearance of such organism.
Therefore, a low pitched male voices (RR) and a high pitched male voice (rr). Heterozygotes have a baritone voice is an example of incomplete dominance.

DNA has two strands. If the sequence of nucleotides of one strand was known, is it possible to use that information to determine the sequence of the second strand? Explain your reasoning for your response using an example DNA sequence. and this is for biomedical science.
Answer:
Yes
Explanation:
DNA, which is the genetic material, is a double-stranded molecule i.e. possess two strands. Each strand is made up of a sequence of nucleotide base, which are complementary to one another. The complementary base pairing rule as proposed by Chargaff states that Adenine (A) base will always hydrogen pair with Thymine (T) base while Guanine base (G) will always pair with Cytosine (C) i.e. A-T, G-C.
For example, If the sequence of nucleotides of one strand was CTAGCGGATC, the sequence of nucleotide of the other strand will be GATCGCCTAG. Hence, based on this question, the information of the sequence of base on one strand can be used to determine the sequence of the second strand.

Mutations are always harmful and lead to the early death of an organism.
Mutations can give organisms new abilities not seen before.
Mutations can alter or stop the production proteins in a way that either alters the appearance or quality of life of an organis
Answer:
The statement that correctly identifies how a genetic mutation affects an organism is that mutations can alter or stop the production proteins in a way that either alters the appearance or quality of life of an organism.
Explanation:
A genetic mutation occurs at the molecular level, in the DNA, and consists of the change of a specific sequence of nucleotides in the nucleic acid.
Since the sequence of DNA bases determines genetic information necessary for the synthesis of specific proteins, changes in the sequence can produce alterations in structural and functional proteins —due to changes in the sequence of amino acids or incomplete synthesis— that affect the appearance or functioning of a living being.
The other options are not correct because:
Although some mutations go unnoticed, most can cause alterations in organisms. Not all mutations are harmful or lead to premature death. Mutations do not produce new abilities.URGENT!!!!!!!!!!!!!

Explanation:
Algal blooms can result in a cloudiness called ____________________, which can reduce the penetration of sunlight.
Answer:
There are no options to this question, however, the answer is:
TURBIDITY
Explanation:
Algal bloom is a term used to describe the excessive and rapid growth of algae species on a water surface. It is caused by the pollution of a water body with nutrients, in a process called EUTROPHICATION.
Asides the low oxygen effect of this algal blooming on a water body, it can also form a cloudiness on the surface of the water body. This cloudiness causes the water to be unclear in a process that is called TURBIDITY. In other words, the water that is affected by algal bloom is said to be "TURBID" and can reduce the penetration of sunlight.
The blood Group of Mother is O. The Blood Group of the Child is B. Man Exonerated If He to Blood Group?
Answer:
If the mother's blood type is O, and the child's blood type is B, a man would be exonerated from paternity if he has blood type A or O.
Explanation:
In the above case, if a mother has blood type O and her child has blood type B, a man can be exonerated from paternity only if his blood type is A or O, and responsible if he is type B or AB.
The blood type is defined by the presence of surface antigens in the red blood cell, called A and B. The presence of each antigen is determined by a gene present on the parental chromosomes.
Blood type A corresponds to the presence of gene A, and its genotypic expression can be A/A or A/O. Type B blood, whose genotype is B/B or B/O, is due to the presence of a gene containing the B antigen. AB blood —due to codominance— has one gene for A and another for B, with genotype A/B. Blood type O, characterised by the absence of surface antigens, behaves like a recessive trait, which only manifests itself in the absence of surface antigens A and B. The genotype is O/O.By making a hypothetical crossing between mother and man, one can observe why he can be exonerated.
Man with blood type O
♂ O|O
♀ O|O
Alleles O O
O O|O O|O
O O|O O|O
The only possibility, in this case, is to have children with type O blood. No chance of children B.
Male with blood type A
♂ A|O
♀ O|O
Alleles A O
O A|O O|O
O A|O O|O
In this case there is a 50% chance that the children will be blood type A and 50% chance that they will be O. No chance of children B.
In the case of a man A|A the result is 100% probability of children A|O, and no probability of children B.
So, a man with blood types A (any genotype) and O, can be exonerated from paternity, since it is impossible for him to have a child of blood type B, when the mother is of blood type O.

the four nitrogenous bases present in DNA are
Adenine(A)Thymine(T)Guanine(G)Cytosine(C)The DNA sequence that produced the mRNA sequence uracil, guanine, cytosine, guanine adenine uracil adenine adenine
Answer:
The DNA sequence that produced the mRNA sequence uracil, guanine, cytosine, guanine adenine uracil adenine adenine during transcription is adenine, cytosine, guanine, cytosine, thymine, adenine, thymine, thymine.
Explanation:
Transcription of DNA into messenger RNA (mRNA) is a process in which the specific nucleotide sequence is transferred from one molecule to another, through the synthesis of mRNA molecules from a DNA strand.
The complete transcription process is done by nitrogenous base complementarity, where mRNA receives the sequence of complementary bases according to the DNA sequence:
Adenine is complemented with uracil, since in RNA the thymine is substituted by this uracil. Thymine is complemented with adenine. Cytosine is complemented with guanine. Guanine is complemented with cytosine.Thus an uracil mRNA sequence, guanine, cytosine, guanine adenine uracil adenine U-G-C-G-A-U-A-A comes from a DNA sequence adenine, cytosine, guanine, cytosine, thymine, adenine, thymine, thymine or A-C-G-C-T-A-T.
