Biology

Mashcka [7]3 years ago

Gram-positive microorganisms have a thicker layer of peptidoglycan which traps a greater amount of the gem violet included and upon de-colorizer discharges approximately caught stains. 



Gram-positive cell dividers contain a thick peptidoglycan layer with teichoic acids. Gram-negative cell dividers contain a thin peptidoglycan layer that is encompassed by a thick plasma film. Gram-positive microorganisms will recolor purple in view of their thick peptidoglycan cell divider.

Use the information below to answer the following question(s). In a survey, the rate of heavy smokers was reported as 270 per 10
Eddi Din [679]

The probability that neither of them is a heavy smoker is 0.53 or 53%

<h3>What is genetic probability?</h3>

Probability serves to mathematically estimate the possibility of events that happen by chance, that is, as a matter of luck.

In this case:

Probability that selected one is heavy smoker is:

p=270/1000=0.27

Number of individuals selected  is 2 and We know that:

P(X=x)=nc_x(1-p)^{n-x}(p)^x

We need to prove that X=0:

P(X=0)=nc_0(1-0.27)^{2-0}(0.27)^0

P=0.5329

What does paleontology, biogeography, embryology, and anatomy reveal bout evolution
Ugo [173]

Paleontology deals with fossils and helps in learning the changes of living organisms in sequence.

Biogeography deals with the distribution of species across the mother earth.

Embryology deals with the study of the similarities and difference that exists in the embryos of different species or organisms.

Anatomy deals with the study of the similarities and difference that exists among different species or organisms.

<u>Explanation: </u>

As an organism dies, the remaining of these organisms will be buried in soil. These are fossils. Paleontology supports evolution with the information that are related to the fossils, footprints etc. With these we can study the evolution of organisms and also the changes they undergo. There are some technologies like radiometric dating that can be used for the determination of these rocks and fossils ages.

Charles Darwin suggested that the evolution of species were form their ancestor. Biogeography supports evolution by explaining about the distribution of different species over the earth. Embryology and Anatomy supports evolution by describing about the similarity and difference in the species of living organisms. Embryology deals with the embryos and anatomy deals with the structure.
