Answer:
I think it is B it should be but I could be wrong
Explanation:
I dont have an explanation
Answer: the sum of the masses of the individual protons and neutrons is less than the mass of the stable Nucleus
Explanation:
Nuclei fission involved bonds breaking with the loss of quantity of Energy by the protons and Neutrons
Remember : e=mc2
Therefore, this breakage of bonds result in loss in masses of p and n.
However, in intact Nucleus the energies of the p and n are trapped in the intact bonds holding them together therefore heavier masses than when broken down.
Answer:
True.
Explanation:
Polygeny occurs in organisms with complex genomes, when several pairs of genes interact to determine a trait, each with an additive effect on the other. Thanks to this type of interaction there is a very wide variety of phenotypes and genotypes for some characteristics. The interaction of these phenotypes with the environment further increases this variation, such as skin color and height, etc. In other words, polygeny is the state of a particular trait determined by the relationship or action of various genes.
Answer:
The organelles are found in a plant cell include - chloroplasts , plastids, and a large central vacuole. The chloroplasts contain a green pigment chlorophyll that is responsible for the process of photosynthesis.
Answer:
The correct option is A. The oxygen atoms diffuse through the atmosphere and are inhaled by animals.
Explanation:
Photosynthesis can be described as a process in which plants use the light from sun to convert carbon dioxide and water into glucose. Oxygen is made as a by-product of this reaction. This oxygen is released into the atmosphere by the plants through the mechanism of diffusion.
The oxygen released into the atmosphere is taken up by animals. Animals utilize this oxygen for the process of respiration.
The process of respiration and photosynthesis are opposite to each other.
