Answer:
Offspring-heterozygous genotype SsEe
Explanation:
If we name the gene for the body color with S and gene for the eye color with E and if the brown body is dominant over ebony body, while red eyes are dominant over sepia eyes, than the genotypes of the parents would be: female-SSEE, male-ssee
P: SSEE x ssee
Female gametes SE, male gametes se
F1: SsEe all of the offspring would be heterozygous.
Answer:
During meiosis 1, the parent cell with double the normal amount of chromosomes, splits into two diploid cells (have enough chromosomes to survive). During meiosis 2, the two diploid cells each split into two haploid cells (have half the amount of chromosomes to survive). Meiosis ends with four haploid cells.
Answer:
<u>Provide support and energy</u>
Explanation:
Polysaccharides are made up of many monosaccharides the common types include starch, cellulose, glycogen, chitin and lignin. Starch is present as stored food in plant tissues and can be hydrolysed into monosaccharides to provide energy.
Cellulose and chitin are structural components. They give the plan cells their definite shape and the exoskeleton in arthropods respectively.
The correct answer is tick on a dog.
The parasitic relationship can be defined as the relation in which one organism feeds on the other organism for their nutritional purpose. It can also harm the other organism by any means. Here, tick on the dog is dependent on the dog for its nutritional requirement. This is an example of parasitic relationship between dog and tick.
The best answer is A.
As soon as the blood vessel wall is broken or damaged, a series of reactions activate platelets so that they stick to the site of injury. The platelets are able to hold to the blood vessel wall by means of a protein substance called von Willebrand's factor.
Collagen and thrombin then act at the site of injury and induce platelets to clump or stick together, forming a mesh that plugs the broken part. Special clotting protein help sequester more platelets to the plug which finally becomes a blood clot.
