A heterozygous organism has
1.three different alleles for a trait
2. Two identical alleles for a trait
3. Only one allele for a trait
4. Two different alleles for a trait

Answers

I'm completely sure your answer would be D.

It has two different alleles for a trait!

An organism that is heterozygous has two different alleles for the same trait. Therefore, the correct option is B.

Alleles are genetic variants that affect the way a trait is expressed in different ways. During sexual reproduction an organism receives one allele from each parent. If these alleles disagree, the organism is said to be heterozygous for that trait. Two different alleles enable genetic diversity and the possibility of different phenotypic outcomes. A dominant allele may be expressed as a result of heterozygosity, while the effect of a recessive allele may be obscured. This genetic diversity is important for evolution because it gives rise to natural selection and the ability to adapt to changing conditions.

Therefore, the correct option is B.

A biologist is studying a structure that is made up of two layers of phospholipids. What is she most likely studying?

Answers

Answer:

Phospholipid Bilayer

Explanation:

The cellular phospholipid bilayer has 2 layers of phospholipids(obviously), but keep in mind that the heads of said phospholipids are hydrophillic(loving water) and the tails are hydrophobic(hating water). This makes the 2 layers line up with heads facing away from each other and tails facing each other. This is so the bilayer can exist in the aqueous enviorment outside the cell as a barrier and inside the aqueous enviorment of the cell to transport materials in and out of the cell.

Answers

Answer:

So I think you're trying to ask where transcription errors take place, which I would say is A.

Explanation:

DNA transcrption is when DNA is converted to RNA, which is then sent to ribosomes in the cell to make specific protiens(this is how viruses destroy cells, they use this system to make more viruses by causing viral RNA or DNA(transcripted)to be given to ribosomes) Anyway, transcritpion makes certain sequences of Amino acids for protiens, so an error is going to affect this area first, which can cause large systematic problems later.
