The answer that makes the most sense of the 4 given is "producers".
Answer:A, B, C
Explanation:
A. The phospholipids are arranged in bilayers withe the Polar head groups oriented towards the extracellular side and the cytoplasmic side with a hydrophobic core.
The plasma membrane also contain membrane protein
B. Some Integral protein are Transmembrane protein the span the membrane and provide a hydrophilic channel and are selective for particular solute such as enzymes, antigens, hormones
The peripheral protein exit on the surface of the bilayer the serve as signal protein
C. The membrane lipid bilayers are not static or rigid. They show free lateral movement of its components hence the membrane is fluid in nature. Fluidity enables the membrane to perform endocytosis and exocytosis
Answer: the correct option is D (There are no circumstances in which animal work may begin before IACUC approval)
Explanation:
The IACUC known as Institutional Animal Care and Use Committees is a local working group that research facilities must appoint in accordance with the Animal Welfare Act , Policy on Human Care and Use of Laboratory Animals. It was introduced to research system by the U.S. government in 1986. The policy protects all warm-blooded animals except rats, mice, and birds bred for research. For an institution to use a specie that is covered by the policy, it must obtain their approval before work begins. I hope this helps. Thanks.
Answer:
Prokaryotic, and eukaryotic cells share basically four common features:
1) A plasma membrane which is known as outer covering membrane it helps to separate the interior part of the cell from its surrounding.
2) Cytoplasm which is consisted of gel like region inside the cell where other parts of the cell are found.
3) Genetic material of the cell which is known as DNA.
4) Ribosomes, which helps in protein synthesis.
