Answer:
A
Explanation:
Meiosis results in gametes with one half the number of chromosomes of the parent cell.
Macromolecules are nucleic acids which are the source of Immediate energy?
Answer:
Primary producers (autotroph organism), primary consumers (herbivores), secondary consumers (carnivores), decomposers
Explanation:
The trophic web is the process of energy transference through a series of organisms, in which every organism feeds on the preceding one and becomes food for the next one. The first link is an autotroph organism or producer, such as a vegetable, that can synthesize organic matter from inorganic matter. The next links are the consumers: herbivores are primary consumers and feed on producers. Carnivores are secondary consumers and feed on herbivores, and so on. The last links are the decomposers, microorganisms that act on dead animals degrading organic matter.
When one of the links disappears, it affects the superior links as they will not have their food source. The immediately anterior link will be beneficiated, as it will not be eaten by its predator. And finally, as this last link will overgrow, it will consume greater quantities of its food, causing a decrease in its anterior link.
Answer:
The correct answer is - 20000, 25,000 genes.
Explanation:
Genes are made by the functional and physical unit of the heredity called DNA. Genes are the precursors or encoded instructions to make a specific protein. Genes can be small or large depending on the DNA bases present in it which can be hundreds to millions in numbers.
According to the Human Genome Project, which found out the total genes present in a human genome between 20000 to 250000 genes approximately.
Thus, the correct answer is - 20000, 25,000 genes.
Answer:
All living things have certain traits in common: Cellular organization, the ability to reproduce, growth & development, energy use, homeostasis, response to their environment, and the ability to adapt. Living things will exhibit all of these traits.
Explanation:
All living organisms (whether they are bacteria, archaea or eukaryote) share several key characteristics, properties or functions: order, sensitivity or response to the environment, reproduction, growth and development, regulation (including homeostasis), energy processing, and evolution with adaptation.
