The supporting structure of the cell that is also involved in movement is most likely the cytoskeleton.
Answer:
C
Explanation:
Ice-covered surfaces are highly reflective of the sun's rays therefore prevent those areas from warming as much as the areas where the ice is replaced with darker, less reflective surfaces which absorb heat and thus contribute more to global warming. Albedo is the percentage of radiation reflected by the earth's surface. Clear surfaces have greater albedo values than dark surfaces.
<u>Evolution is sometimes a controversial:</u>
Evolution is the most scientific explanation about how the life forms of earth originated and turned into the form that we see today.
I don’t think there should be a controversy because there is no other explanation that proves to be more logical than the theory of evolution. Evolution is a theory that has several supporting proofs and the theory itself was formed after several years of detailed study and observation.
I don’t think alternatives to evolution should be taught at schools. Alternative theories to evolution are based on various religious beliefs which lack a scientific basis.
Schools should be a place that enables students to do productive scientific thinking and teaching alternatives to evolution wouldn’t be a good idea.
Answer:
40: 3
41: 1
Explanation:
40: When trying to achieve a better or sharper image on a microscope, the part of the microscope that needs to be adjusted is the "fine focus" which is responsible for better/sharper image by either moving the stage or the eyepiece. The fine focus is labelled C in the image.
41: Chromosomes contain hereditary materials (genes) that are responsible for an organism's trait. All organisms have their individual genetic materials in their cells and in the case of the onion cells, it's genetic materials (genes) are stored in the chromosomes hence it is important the cells have these chromosomes. Thus, the correct option is 1
Chromatin is a simpler for of a chromosome. For example, in mitosis (somatic cells dividing) chromatin is in the nucleus, however when it condenses, it forms chromosomes.
