Explanation:
G- green feathers
g- yellow feathers
L- long beak
l- short beak
Letters are the easiest way of modeling a Punnett square. The big letters mean it's dominant, while the lower case means it's recessive. Dominant traits will show up over the recessive traits. The answer is 75% because if the female is heterozygous, her alleles would be Ll, and as I said before, the big letters take over the little letters in any case.
I hope this helps :)
Answer:
The correct answer is - Histones are positively charged.
Explanation:
Histone is an octamer that is made up of four proteins and each protein has 2 copies. These proteins are H2A, H2B, H3, and H4. Histone proteins are mainly made up of positively charged amino acids like arginine and lysine which gives histone proteins an overall positive charge.
This positive charge of histone plays important role in the binding of DNA around it because phosphate group present in the DNA makes DNA negatively charged molecules that are attracted by positively charged histone protein by electrostatic interaction.
This interaction results in the wrapping of DNA around the histone proteins and then compaction of DNA into chromatin. Therefore the right answer is- histones are positively charged.
Answer:
correct answer is symporter and active
Explanation:
- A symporter is an integral membrane protein involved in the transport of two different molecules in the cell membrane in the same direction.
- The symporter works in the plasma membrane and the molecules are transported to the cell membrane at the same time.
- Active transport is the movement of molecules across a cell membrane from a low-concentration region to a high-concentration region against the concentration gradient.
- Active transport requires cellular energy to achieve this movement.
Answer: Codominance
Explanation:
<u>Codominance is a relationship between two versions of the same gene, called alleles.</u> Individuals receive an allele from each parent and if the alleles are different, the dominant allele will normally be expressed, while the effect of the other allele (called recessive) is masked. However during codominance, the two allele genes are expressed, but without mixing.
A true-breeding organism is one that only passes down certain phenotypic traits to the offspring. So the organism is homozygous for every trait and they have identical alleles for specified traits, which are homozygous dominant or recessive.
The red flower could be homozygous dominant (AA) while the white flower could be homozygous recessive (aa). Then 100% of the offspring will be Aa, and since A (the dominant allele which masks the effects of the recessive allele) is red, then we would expect 100% of red flowers. However since they are white with red splotches, then this is an example of codominance.

Without any inference and related test , a write up or text is a plain theory or just a summary.
