Answer: Asexual reproduction
Asexual reproduction is a mode of reproduction in which a single parent is involved to produce the offsprings. This occurs in simple organisms. This does not requires formation of gametes like sexual reproduction. The offsprings are identical to the parent organism. Here, mother colony of protists, volvox gives birth to daughter as only single parent is involved it is a asexual mode of reproduction.
Gross motor skills involve large muscles in the arms legs and torso. The general guidelines for gross motor development for children 4 years of age include running, jumping and climbing well and control their direction. They can hop on one foot and they start to skip at this age. At this stage, they are also able to ride a tricycle and reliably catch a ball.
The answer to your question is 4.
1) Adenosine triphosphate (ATP) is thought of as the "molecular currency" for energy transfer within the cell. Function: ATPs are used as the main energy source for metabolic functions. They are consumed by energy-requiring (endothermic) processes and produced by energy-releasing (exothermic) processes in the cell and Cells store energy in the form of ATP; cells make 36 ATP through cellular respiration.
2) Energy is normally stored long term as carbohydrate, in plants the storage polymer is starch whereas in animals the storage polymer is glycogen. Both of these are formed from the monomer alpha-glucose (C6H12O6). When energy is required by the cell, storage polymers are hydrolysed to yield glucose molecules, which are the starting point of respiration, a series of chemical regions yielding ATP, the universal cellular energy release molecule.
I think homologous structures is a great example and idea that supports the theory of evolution. Homologous structures shows us how our futures evolved by natural selection.
