Blood groups are inherited from both parents. The ABO blood type is controlled by a single gene (the ABO gene) with three types of alleles inferred from classical genetics: i, IA, and IB. The I designation stands for isoagglutinogen, another term for antigen.

Alecsey [184]
If I am not wrong, I believe the answer is Producers. The reason as to why I say that producers is the answer is because in every food chain, there needs to be a base. That base is what provides the starting energy that will later on move up in the food chain.

Roan coat color in cattle develops through incomplete dominance of the gene for red color and its allele for white. what crossin
slava [35]
<span>Roan is a combination of white hairs with red hairs. When we see cattle like this, they look pink because it resulted from a mix of white and red.

Red allele: A
White allele: a
</span>
<span>A heterozygotic animal has this genotype: Aa
Like i said previously this is the mixture of colors so the animal would be pink.

A red coat color has this genotype: AA
A white coat color has this genotype: aa

To get all the herd to be</span><span> roan-colored cattle the combination of parents should be: AA x aa. -> 100% roan
Another possible way to obtain would be</span><span>roan-colored cattle: Aa x Aa or aa x Aa (in this case there would be less probabable to obtain road).</span>

How would a tsunami most likely affect the abundance of aquatic organisms in the intertidal zone of the ocean?
AlexFokin [52]

Answer: C). A tsunami would decrease abundance by causing physical damage to the organisms and their ecosystems.

An intertidal zone is also known as littoral zone. It is the region which is covers the foreshore and seabed. This region is exposed to the affects of tides. This region is highly vulnerable to tsunamis. The tsunami will disturb the habitat of organisms living in intertidal zone. Therefore, will result in decrease in abundance of aquatic organisms.

Which statement correctly describes one way that the properties of water affect heat and temperature? Water retains more heat th
Sphinxa [80]
I believe the correct statement is that Water absorbs heat when it changes to vapor, helping to keep animals cool through perspiration. Water has a high heat of vaporization, the amount of energy needed to change one gram of a liquid substance to gas at constant temperature. In humans and other organisms, the evaporation of sweat, which is 90% water, cools the body to maintain a steady temperature.
