The rabbit cell is an animal cell. It has a two layered lipid membrane. The lipid membrane is non-polar in nature and will permit the movement of non-polar substrates across itself. Ions and large charged particles cannot pass across this membrane unless the cell expends its store of energy to facilitate their active transport into the cell. Hence Calcium ions and sodium ions will not diffuse across the rabbit cell membrane, whereas water (uncharged), glucose (polar) and oxygen (uncharged) will diffuse across the lipid membrane.
The correct answer is A. A sperm
Explanation:
Sperms are a type of reproductive cells that are essential for sexual reproduction. Sperms are male reproductive cells different from eggs that are female cells. Additionally, these can have flagella that allow them to move to reach the egg or be non-motile. In the case of human sperms, these have a flagella and also they contain 23 chromosomes; additionally, in this there is 1 allosome chromosome that defines sex and in males and therefore sperms can be either X or and 22 autosomes that refer to chromosomes not related to sex, this is also particular from sperms as eggs in humans can only have an X allosome. According to this, it is a sperm the cell that contains 22 autosomes and a Y chromosome.

Some people who protested against it include; U.S. Fish and Wildlife Services (FWS) and U.S. National Oceanic and atmosphere Administration. (NOAA)
- The law requires federal agencies, in consultation with the U.S. Fish and Wildlife Service and/or the NOAA Fisheries Service, to ensure that actions they authorize, fund, or carry out are not likely to jeopardize the continued existence of any listed species or result in the destruction or adverse modification of designated critical habitat of such species. Which is some part of the reason they took action.
