Cell membranes contain membrane proteins that allows all the interaction that occurs within the cell. It makes the cell membrane selectively permeable because of its characteristics as being fluid or its fluidity which means to say that they can move freely within the lipid bilayer. The membrane proteins can also be stored in the lipid bilayer together with the enzymes. It cannot be denied that membrane proteins have a lot of functions based on its type. They can be integral proteins, peripheral proteins and lipid bound proteins.
DNA: deoxyribose, a phosphate<span> group, and a </span>nitrogenous base.<span>The </span>nitrogenous base<span> will be one of these four: Guanine, </span>Adenine<span>, </span>Cytosine, or Thymine.

Answer:
C
Explanation:
Gymnosperms are mostly cones, like Pine cones.
Angiosperms are vascular plants that can produce seeds, fruit, and flowers.
So basically, Gymnosperms really cannot do anything while Angiosperms can.
The answer is hard tissue.
Usually, hard tissue, such as bones and teeth or exoskeleton is much more preserved than soft tissue (organs, skin, etc.). Fossils become fossils by a process of mineralization. Hard tissues are more mineralized during life than organs. So it is no surprise that hard tissues take part in the process of mineralization and is preserved in fossils, unlike soft tissues.
<h2>Answer:</h2>
The goal of transcription is to produce a RNA from a DNA segment.
<h3>Explanation:</h3>
- Transcription is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA).
- DNA safely stores genetic material in the nuclei of cells as a blue print or template.
- The purpose of translation is to synthesize proteins, which are used for millions of cellular functions.
