Answer:
The hard parts of organisms, such as bones, shells, and teeth have a better chance of becoming fossils than do softer parts. One reason for this is that scavengers generally do not eat these parts. Hard parts also decay more slowly than soft parts, giving more time for them to be buried.
Explanation:
LDL (low-density lipoprotein) carry cholesterol from the liver to the tissues and can contribute to the formation of plaque that builds up in the arteries.
<h3>What are lipids?</h3>
Lipids are soluble in fat and to circulate in the blood, which is an aqueous medium, they form lipoprotein complexes called lipoproteins, these constitute a transport medium and circulating reservoir for lipids.
<h3>Characteristics of LDL (low-density lipoprotein)</h3>
- Low-density lipoproteins, composed of 50% triglycerides, are the ones that transport the lipids synthesized in the liver to other parts of the body.
- LDL, composed mainly of cholesterol, when in excess, also deposits it on the walls of the arteries, contributing to the formation of plaque.
Therefore, we can conclude that excess LDL (low-density lipoprotein) poses a health risk because it facilitates the accumulation of fat in the arteries.

The cell membrane functions as a selective barrier. We call these kind of membranes as differentially permeable or semi permeable membrane. It can decide what substances can pass in and out. Therefore it can surround the cytoplasm (which is the inside of a cell) to separate the cell's content from the surroundings.
Answer:
it says that plants are the main source of nutrients and energetic materials and when the cow feed on them, it consumes some of the benefits that we miss when we eat beef
I think the answer would be yes, the nuclear membrane would be present. It is involved during the process of cytokinesis and is remain unchanged even the process is done. It is a very important part in order to have a healthy cell function.
