Answer:
Triploid
Explanation:
The process whereby gametes produced by different sexes of the same species of organism come together is called FERTILIZATION. A gamete is said to be HAPLOID (n) if it contains one set of chromosomes while it is DIPLOID (2n) if it contains two sets of chromosomes.
Hence, if an haploid (n) and diploid (2n) gamete unites, a zygote that is TRIPLOID (3n) emerges or forms. A triploid zygote will have three sets of chromosomes i.e. n + 2n = 3n.
Answer:
The incorrect statement is -C. They are ALL parasites that harm their host by living in or on it.
Explanation:
Protists are organism shows the vast difference and have a single cell microscopic eukaryotic cell. These are based on their characteristics similar to plants or animals divide them into two groups called plant-like protists and animal-like protists.
Animal-like protists are also a eukaryotic unicellular organism that depends on other organisms for their food so they are called heterotrophs. Some of these organisms also parasites and affect their host negatively. These are also organisms that are live symbiosis and help other organisms.
The best answer is D. He extracted and observed DNA from white blood cells. He is a Swiss physician and a biologist who is known to be the first researcher to identify nucleic acid. He isolated various phosphate-rich chemicals , which he called nuclein or what we know now as nucleic acid, from white blood cells' nuclei which paved the way for him to discover and identify DNA.
Answer: crossing over, process in genetics by which the two chromosomes of a homologous pair exchange equal segments with each other. Crossing over occurs in the first division of meiosis . At that stage each chromosome has replicated into two strands called sister chromatids.
Transpiration and guttation are the two important process of removal of excess water from the plants. However, the two processes are different from each other. Transpiration is the removal of water from the stomata present on the leaves. On the contrary, guttation is the process of removal of water from the hydathodes.
