Answer:
A.) transcription factors
Explanation:
Transcription factors are often very important in initiating patterns of gene expression that result in major developmental changes.
<u>Answer:</u>
Limited resources contribute to evolutionary change in animals by increasing Intra-specific competition.
<u>Explanation:</u>
- Intra-specific competition means competition among the members of same species.
- Individual of same species have same ecological niche i.e. how an organism is related with biotic and abiotic aspect of environment.
- So they require same resources of their survival. When population of any species increases then there is high chance of intra-specific competition because of limited resources.
- Intra-specific competition also determine the population size of species. For example, competition among shark rodents.
Answer:
go through a metamorphosis
Explanation:
METAMORPHOSIS is the change in the form and often habits of an animal after the embryonic stage during normal development.
For Example: the transformation of a caterpillar into a butterfly, OR a tadpole into a frog.
Note that the other options given are WRONG because they are characteristics or features of either of them, NOT both.
Answer:
Molecules of gas starts movement when they get energy from the sun in the form of heat.
Explanation:
Molecules of gas absorbed heat energy coming from sun. This heat energy is converted into kinetic energy due to which gas molecule moves faster. Volume of gas molecules also increases due to expansion of molecules by the absorption of heat energy. So more space is occupied by gas molecule as compared to liquid molecules.
