Answer:
The correct answer will be option-A.
Explanation:
Genetic variation is the difference in the DNA sequences of individuals in a population. Genetic recombination is the main reason for the diversity of organism on earth.
The genetic variation takes place during gamete formation by recombination of DNA sequences which takes place during prophase of meiosis I.
Since genetic variation involves changes in the coding segments of the DNA called genes which leads to mutations, therefore, flowering time does not influence the genetic variation and option-A is the correct answer
Answer:
2-Air masses are colliding with each other.
Explanation:
have a great day <3
- From the image given below its clear that the warm is rising upwards and as a result of the collision from the cold winds or front from below, hence the development of clouds that make the thunderstorms appear.
- And a result of this turbulent the rising air is pushed and the warm front cycle takes a turn and will lead to either development of cyclone or rainfall.
Can you be more clear in ur question
The answer is <span>c. A and B are both correct
The solubility of some solid depends on temperature. Increased temperature of a solution will increase the kinetic energy of molecules in the solution. Solvent molecules will effectively break apart solute molecules. By breaking them apart, the surface area of solute molecules increases, too. Grinding the material will also break apart solvent molecules and increase their surface area. Increased surface area enables more solute molecules to interact with solvent molecules and the reaction rate increases.
Imagine if sugar will better dissolve in cold or hot water and also if icing sugar or granulated sugar will better dissolve.
Therefore, both increasing the temperature and grinding the material are important to increase the solubility of something.</span>
<span>Much of our understanding of the basic structure and composition of Earth and the other planets in our solar system is not strenuously debated. We can infer a surprising amount of information from the size, mass and moment of inertia of the planets, all of which can be determined from routine astronomical observations. Measurements of surface chemical composition, either by direct sampling (as has been done on Earth, the moon, and Mars) or through spectroscopic observations, can be used to estimate elemental abundances and the degree of chemical differentiation that occurred as the planets condensed from the solar nebula. Remote observations of the gravitational field can be used to understand how a planet's mass is distributed, whereas the strength and shape of the magnetic field provides some constraint on the structure of a metallic core. The specifics of structure and composition, however, are much more debatable. And it is these details that tell us a much more extensive and ultimately more interesting story about the internal dynamics of the planets and their evolution. As a result, trying to determine them is frontier research in almost all fields of earth and planetary science.
