Answer:
Pollen from a plant is a biotic factor.
Explanation:
The reason why pollen is a biotic factor is because the pollen has life and it is basically a living cell which can give life to a flower.
Ansnswer:
False.
No Mendel principled talk about how different genes assemble unregulated with one another to develop reproductive cells
Explanation:
Gregor Mendel was a scientist and the founder of modern science genetics. He made so findings in 1865 and He proposed three laws and they are;
Law of independent assortment which states that two alleles from different genes separated independently to form gamete.
Law of segregation states that a pair of gene separated to for reproductive cells.
Law of dorminant inheritance states that in heterozygote, dorminant allele will masked the recessive allele.
Answer:
The answer is A.
Explanation:
The bacteriophage is an organism that attacks bacteria and uses them to replicate it's DNA to reproduce and multiply.
If all the amino acids of the bacteria are flagged with fluorescent tag, then the new bacteriophage's DNA will exhibit the fluorescent tag because it will be constructed using the bacteria's protein molecules in the first place. So the answer is A.
I hope this helps.
In human audition, the vibration of the ossicles is triggered by the vibration of the tympanic membrane (the eardrum) and transmitted directly to the fluid and membranes of the inner ear.
The inner ear is shaped like a snail with a thousands of tiny hair cells in it and it is called the cochlea. Hair cells change the vibrations into electrical signals that are sent to the brain through the auditory nerve.
Answer: A protein domain is a region of the protein's polypeptide chain that is self-stabilizing and that folds
independently from the rest. Each domain forms a compact folded three-dimensional structure. Many proteins consist of several domains.
One domain may appear in a variety of different proteins. Molecular evolution uses domains as building blocks and these may be recombined in different arrangements to create proteins with different functions.
In general, domains vary in length from between about 50 amino acids up to 250 amino acids in length.
The shortest domains, such as zinc fingers, are stabilized by metal ions or disulfide bridges. Domains often form functional units, such as the calcium binding EF-hand domain of calmodulin.
Because they are independently stable, domains can be "swapped" by genetic engineering between one protein and another to make chimeric proteins.
