Proteins (def - organic molecules composed of very long chains of amino acids that play a crucial role in almost everything a cell does)
Answer:
20% cytosine
Explanation:
Their is 30% thymine and a total of 30% adenine, and there is 20% cytosine and 20% guanine.
Answer:
32 possible combination of chromosome
Explanation:
According to the law of independent assortment as proposed by Mendel, alleles of a gene will separate into gamete independently of the alleles of another gene. Since this organism contains 10 chromosomes in its somatic cell, it will undergo meiosis to produce half number of chromosomes in its gametes i.e. 5 chromosomes.
If we know the haploid number of chromosomes of an organism i.e. n, we can calculate the possible combination of chromosomes that will be present in its gametes as a result of independent assortment during meiosis using the formula:
2^n, where n= haploid no. of chromosome
If n is 5 chromosome in this case, the possible combination of chromosome in its gametes will be 2^5 = 32. Hence, as a result of independent assortment, an organism with 10 chromosome in its somatic cell will produce 32 possible combinations of chromosome in its gametes.
Answer:
1. Medulla
2. Heart rate and breathing
Explanation:
The brainstem is the part of the brain that was formed earlier in the history of the evolution of the brain, therefore, is present in the posterior region of the brain. The brainstem is composed of three parts called the pons, the midbrain and the medulla.
The medulla is the portion which is connected to the spinal cord and thus the transfers the signals form the spinal cord to the brain structures.
The brainstem controls the main functions of the body like the breathing rate, the heart rate, consciousness, blood pressure and many involuntary functions.
Thus, Medulla and Heart rate and breathing are correct.
