As the name says the goal of the descriptive investigation is to describe.
This type of investigation has no hypothesis, but only a question. With this type of investigation Tyler will be able to observe all types of insects and study the insects in many various aspects and provides a bigger overview, because it uses both quantitative<span> and qualitative data.</span>
Burial practices has not lead to significant changes in Earth’s biomes.
From the punnet square it can be identified that,
R- dominant allele(red)
r- recessive allele(white)
Rr- heterozygous red
RR-homozygous red
rr-homozygous white
It is a monohybrid cross because it is a cross between paternal and maternal genotypes possessing a pair of contrast characters.
Answer:
D. Macromolecules
Explanation:
Lipids and proteins are both types of macromolecules. Macromolecules are molecules made up of more than one atom, and they are larger than other types.
The endosymbiont theory explains the origin of the eukaryotic cell organelles where the cells were engulfed but not digested by the larger prokaryotic cells and in the process developed into the chloroplast, mitochondria and other organelles.
(A) The theory was trying to explain the evolutionary origin of the various cell organelles and,
also explains the dependence of cells on one another.
(B) The evidences that supported the Endosymbiotic theory includes;
-The photosynthetic bacteria; This bacteria utilize the sun's energy to make energy hence the oxygen released from the process accumulated in the atmosphere thereby leading to the death of the anaerobic cells.
-Organelles have their own DNA and divide independently, therefore Margulis predicted that if the organelles were really prokaryotic symbionts, then they would have their own DNA.
- The study of fossils showed the aerobic cells in it, therefore the cells could use the toxic oxygen and convert it into ATP(energy) and water. Organisms that could thrive in aerobic environments were now best suited to the environment.
