Answer: A COMMUNITY
Explanation:
A biotic community, also known as a biota or ’biocoenosis’, is the group of ORGANISMS of two or more different species that live together and interact with each other within an environment or habitat. Together, the biotic community and the physical landscape or abiotic factors make up an ECOSYSTEM.
A group of organisms constitute POPULATION. But when several populations share a common habitat and its resources, they interact among themselves and develop into a biotic community or simply, a community.
Answer:The cells that produce hair contain a lot of ROUGH ENDOPLASMIC RETICULUM , while the cells that produce the oils that coat the hair contain a lot of SMOOTH ENDOPLASMIC RETICULUM.
Explanation: ROUGH ENDOPLASMIC RETICULUM or RER is a cisternae organelle that have two faces: the cytosolic face and the nucleus face. The cytosolic face is studded with ribosomes that are responsible for synthesizing proteins, a process known as translation. In the cells that produce hair, keratinocytes, the main protein synthesized is keratin.
SMOOTH ENDOPLASMIC RETICULUM is an organelle that lacks ribosomes and the function is related to lipid synthesis, different case that proteins synthesis. Specialized cells located in the SER (smooth endoplasmic reticulum) produces the oils that coat the hair called sebum to lubricate the hair. These cells secrete the sebum in an holocrine way. The composition of the sebum is made of triglycerides, wax esters, squalene.
Answer: In females, most of gametogenesis occurs during embryonic development. Primordial germ cells migrate into the ovaries at week 4 of development and differentiate into oogonia (46,2N).

Answer:
Explanation:
Fuligo septica is a species of plasmodial slime mold, and a member of the Myxomycetes class. It is commonly known as the scrambled egg slime, or flowers of tan[2] because of its peculiar yellowish, bile-colored appearance. Also known as the dog vomit slime mold, it is common with a worldwide distribution, and it is often found on bark mulch in urban areas after heavy rain or excessive watering. Their spores are produced on or in aerial sporangia and are spread by wind.
