Answer:
A They can possess tissues and organs.
Explanation:
Multicellular are those organisms which are made of more than one cell. All multicellular organisms have tissues and organs. Each organ has a specific function. For example, heart is an organ which is responsible for the pumping of blood throughout the body. Kidney is also an organ which helps in the purification of blood and send waste material such as urine to urinary bladder.
Answer:
C
Explanation:
The correct answer would be <u>a genotype that was different from that of both parents.</u>
Let us assume that the allele for height is A (for tall) and a (for short). Homzygous tall plant would have the genotype AA while homzygous short plant would have the genotype aa. Crossing both genotypes:
AA x aa
Aa Aa Aa Aa
<em>All of the offspring, even though have the same phenotype as one of the parents, have unique genotype from either of the parents. While the parents are AA/aa, the offspring are Aa.</em>
The correct option is, therefore, C.
Answer:
Estrogen binds to specific receptors inside many kinds of cells, each of which have different responses to its binding. intracellular receptors are present only in target cells
Answer:
Diffusion forces protons to travel through ATP synthase because the membrane is not permeable to protons
Explanation:
ATP synthase is the enzyme that allow the production of ATP from adenosine diphosphate. The ATP synthase allows is the protein found in the cell membrane, which allow protons to pass through the membrane.
The concentration gradient can be compared to diffusion of water where particles move from region of higher concentration to lower concentration through a permeable membrane
In this case, the concentration gradient will force the proton through the membrane , so that, the free energy can be used by ADP to produce ATP.
Answer:
the genotype of the parent guinea pigs are as follows:
RrBb (rough, black) and Rrbb (rough, white)
Explanation:
Since the phenotype of smooth coat is present in the offspring, the parent genotype cannot have RR alleles for their coat. Similarly, the rough, black parent cannot have BB alleles in its genotype because that will not yield a white coat color in its offspring.
After making the dihybdrid cross, the probability obtained for each phenotype is given below:
rough black:
rough white:
smooth black:
smooth white:
Hope that answers the question, have a great day!
