Answer:
Tubules?
Explanation
The trachea, spiracle, and air sac are part of their respiratory system, Howeber, the tubules are what take away the carbon dioxide from their system. Im not sure if they produce the carbon dioixde. But they are a part of what removes the carbon-dioxide from their body.
Explanation:
Silent mutations occur when the change of a single DNA nucleotide within a protein-coding portion of a gene does not affect the sequence of amino acids that make up the gene's protein.
Totipotent cells can differentiate into more types of cells
The given question is incomplete as the genotype of the parents is not given, so the answer is providing in the followings case:
1. dominant parent and recessive parent
2. heterozygous parents
Answer:
1. dominant parent and recessive parent:
dominant parents can be represented by LL and recessive parent is represented by ll, so the gametes would be L, L and l, l.
so,
L L
l Ll Ll
l Ll Ll
so there are all offspring in heterozygous condition as we known one or two dominant allele masks the recessive allele for the trait so 100% offspring can fold their tongue.
2. heterozygous parents
In this case, parents have Ll genotype and gametes would be L and l for each parent so,
L l
L LL Ll
l Ll ll
In this case, one is pure dominant and two heterozygous whereas only one is recessive so, the phenotype of offspring that cant fol the tongue would be:
3/4 = 75%
Answer: Brain stem
Explanation:
The brainstem can be defined as a structure which is present in between the midbrain and the cerebrum. This controls the flow of information from the brain and the rest of the body. It also controls the functions like breathing, heart rate, consciousness, sleep and wake cycle and blood pressure. The brain stem consists of pons, midbrain and medulla oblongata.
