C. the cruciate and collateral
Answer:
Answer is D.Produce non-identical genetically different gametes and reduction of chromosomes,creating a haploid gamete.
Explanation:
Meiosis is essential for sexual reproduction.In humans diploid gamete-mother cells or germ line undergo meiosis to produce haploid gametes.
The chromosomes pairs of each parent undergo crossing over during meiosis.so daughter cells i.e gametes have genetic variations.When gametes fuse and form zygote ,its genetic make up is different from both parents.thus meiosis allows a species to bring variations in next generations.Benenficial variations help organisms to adapt to the changes in environment.
Genotypes of the dog color are:
BB dominant homozygous-brown phenotype
bb recessive homozygous-white phenotype
Bb heterozygous-tan phenotype
Cross between brown and pan dog would be:
P: BB x Bb
F1: BB Bb BB Bb
The ratio would be 1:1 (brown dog:pan dog).
Solution :
A flowchart may be defined as the diagram which represents the process or the workflow of any process. It is the step by step approach to solve or to do the process.
In the context, the the sequence of each of the terms to form a flowchart is :
1. Person starts exercising.
2. The metabolism of the skeletal muscle increases.
3. The demand for oxygen for the skeletal muscle increases.
4. The oxygen sensors causes the local blood cell vessels to dilate.
5. For providing more of oxygen, the blood flow to the skeletal muscle increases.
