madam [21]3 years ago
7 0

Answer:

1. a phospholipid bilayer with various molecules embedded within and floating between the layers

Explanation:

The fluid mosaic model is best described as a phospholipid bilayer with various molecules embedded within and floating between the layers.

This is because this model talks about a phospholipid layer having protein and other molecules in it which aids in it being fluid. The fluid characteristic is what encourages floating between the layers.

How are cancer cells able to get nutrients away from your healthy cells?
chubhunter [2.5K]
<span>well this is an interesting question and i would say it may depend on what type of cancer cells you are growing and what type of "normal" cells your growing. One possibility is that cell fusion events may occur between your cancer cells and normal cells, thus creating a few options 1 - making the normal cell cancerous, 2 - making the cancer cell that fused with the normal cell not cancerous anymore. 3 - either way the fused cell will have a different genotype and hence be a different cell.</span>

Answer: Ecosystem Services

Explanation: Simply put,Ecosystem services refer to all the benefits that man enjoys from his relationship with the ecosystem.Ecosystem services are the benefits that people obtain from ecosystems. Ecosystem services are indispensable to the wellbeing of all people, everywhere in the world. They include provision,regulation and cultural services that directly affect people, and supporting services needed to maintain the other services. From the availability of adequate food and water, to disease regulation of vectors, pests, and pathogens, human health and well-being depends on these services and conditions from the natural environment.

We depend on nature for our survival – without healthy ecosystems, our drinking water isn’t clean nor is the air we breathe. Studies also show that people who spend time in nature tend to be happier than those that don’t. Being outdoor can even act as a natural anti-depressant. With industry and urban sprawl expanding at unprecedented rates, Ecosystem Services attempt to translate the benefits we receive from nature into economic terms so we can better understand the compromise we are making between nature and industrial development.

The sedimentation coefficient:
chubhunter [2.5K]

Answer:

option D is incorrect

Explanation:

the sedimentation coefficient is measured in Svedberg units named after the scientist Theodore Svedberg. the shape of the particle being measured in the ultracentrifuge is one of the factors that determines the sedimentation coefficient. the values are usually not additive as the sedimentation coefficient is based on the rate at which a particle sediments in an ultracentrifuge and not on the size. for example, the sedimentation coefficient of eukaryotic ribosome is 80S but is made up of the 60S large subunit and the 40S small subunit.
