What are your 3 best evidences for evolution?

Biology
1 answer:
Semmy [17]4 years ago
8 0

Answer:

Anatomy. Species may share similar physical features because the feature was present in a common ancestor (homologous structures).

Molecular biology. DNA and the genetic code reflect the shared ancestry of life. DNA comparisons can show how related species are.

Biogeography. The global distribution of organisms and the unique features of island species reflect evolution and geological change.

Fossils. Fossils document the existence of now-extinct past species that are related to present-day species.

Direct observation. We can directly observe small-scale evolution in organisms with short lifecycles (e.g., pesticide-resistant insects).

The cook should compare 3 and 4.

<h3><u>Explanation</u>:</h3>

Yeast is an unicellular fungi whose scientific name is <em>Saccharomyces cerevisiae</em>. This organism is an anaerobic fungi which performs alcoholic fermentation. The alcoholic fermentation is done by the enzyme zymase which is a mixture of different enzymes. This enzymes acts on glucose to form the ethyl alcohol and carbon dioxide from glucose.

Glucose - > 2 Ethanol + 2CO2.

In an open system, the carbon dioxide will evolve as gas and leave the system. So in the container with yeast, the container will loose weight but the other one won't loose any weight.

Review the chart, which shows the population sizes of three African animals in 1990 and in 2000.
iren2701 [21]

The explanation which is best supported by the numbers in the chart is that Lion and cheetah populations compete for the food source of zebras, and lions outcompete cheetahs. Thus, the correct option is A.

<h3>What is Competition in the population?</h3>

Competition in population may be defined as the existence of two or more same or different species that are actively fighting over the same resources and factors that they disseminate.

Competition and predation are the two types of species interaction through which the population of species either increases or decreases.

According to the given chart, it is noticeable that the population drop in predator cheetah and lion populations because of the reduction in zebra lowering population but the in cheetah population is additionally than that of the lion.

Therefore, the correct option for this question is A.
