<span>Not every member of a particular species (one kind of organism) must be able to reproduce in order for the species to survive. If you take homo sapiens for example (Humans) there are many males and females around the world who are sterile and unable to reproduce, yet you still see the human species flourishing. </span>
Answer;
all individual variation is due only to environmental factors
A population of organisms will not evolve if all individual variation is due only to environmental factors.
Explanation;
-Evolution of organisms is influenced by several factors which include; natural selection, random genetic drift, mutation, and gene flow.
-Mutation is a random heritable change in a gene or chromosome, resulting from additions, deletions, or substitutions of nitrogen bases in the DNA sequence. Gene flow works to decrease the variation between the two populations.
-Genetic drift is the random change in allele frequency from one generation to the next.. Natural selection is the process by which some organisms have a greater chance of surviving and reproducing than others due to features that are better adapted to the environment.
I believe the condition is infestation. Infestation is the state of being invaded or overrun by pests or parasites. It can also refer to the actual organisms living on or within a host. For example being invaded by ectoparasites such as lice, mites, or ticks. It may also refer to the presence of an unusually large number of insects or animals in a place, typically so as to cause damage or disease.
Answer:
Female egg cells grow in the ovary.
Explanation:
If we talk about female reproductive system in animals or particularly humans, ovaries are basically the sites where female egg cells are produced. These egg cells are also termed as oocytes or ova. After the production, they are transferred to fallopian tubes where the sperm is also reached and ultimately fertilization occurs. Once the egg gets fertilized, it moves towards another site called uterus. The walls of the uterus get thicker and thicker due to production of specific hormones and help in supporting the baby. You can see attached image for better understanding.
<em>Note: </em><em>The female egg cells grow in ovary but here we specifically focussed on human females. The option is true for all animals.</em>
Hope it helps!
