In Sexual reproduction evolution takes place.
Explanation:
In sexual reproduction, the gametes from the two parents fuse to form a zygote and consequently an organism. The gametes from the two parents provide different alleles for a trait. The different genetic variant or alleles found will cause genetic variation.
The offspring can survive and adapt to the new environment. This leads to natural selection and evolution.
In asexual reproduction changes only occur if mutation takes place otherwise the progeny remains genetically identical so less chance of evolution.
Analogous are the organs having similar function but different origin in different organisms.
Detrimental effects are small or negligible effect of mutation on organism due to the exposure of chemicals or rays.
Only those mutations are heritable which occur in germ cells, mutations of somatic cell do no pass to other generation. Detrimental effect is mainly seen in somatic cells.
Answer:
Organs
Explanation:
It is a system of cells and tissues. Organisms are comprised of organs. Btw what anime do you like?
Answer:
This question is incomplete
Explanation:
This question is incomplete because of the absence of options but the complete question is in the attached picture below.
The human genome is the basic genetic code, or blueprint, for the transfer of traits from parents to offspring through -hereditary transmission- . Studying this code -has revealed- ways to partially correct genetic defects after birth. It is already clear that behavior is rarely controlled by -a single gene- . Rather, almost all behavior involves -multiple genes- , and often specific -environmental- factors influence how genes are expressed.
It would be noted that some of the options were not chosen at all, this is because this question focuses on genes and it's expression. "Nurture and education" and "psychological" are not factors that actually affect gene expression. Also, studying genetic codes has already revealed partial ways to correct genetic defects and hence it would be wrong to choose "may in time reveal". For instance, there are procedures used to identify genetic defects in the spermatozoa of a male which can be screened out and the "good" sperm used to fertilize an egg in-vitro.
Answer:
Fibrous
Explanation:
Proteins are assembled according to their functions. Fibrous proteins usually provide protection and support to cells. They are made up of polypeptides that have elongated shape and assembles in large cables or threads. These proteins are differentiated from globular proteins by their globular form and repeated units of amino acids.
For example the fibrous proteins involved in horns, hair and nails is alpha-keratin. Elastin found in skin and ligament is also a fibrous protein. Collagen includes collagen fibrils that have tensile strength of steel is also a fibrous protein found in cartilages and bones.
