In the Animals cladogram, which trait evolved two different times?Think and discuss: What could cause similar traits to evolve independently in different species?You will find the cladogram in the attached files.
Answer:
Bipedalism is the trait that evolved two different timesDifferent organisms in different spaces and times face the need to adapt to a similar environment. They manage to solve a problem from that particular ecological niche by developing the same traits, even when the involved groups are not closely related.Explanation:
Through the process of Convergent evolution, two phylogenetically independent organisms get to develop similar structures. These structures make possible a better performance in a similar environment. These organisms are morphologically or ethologically similar in their whole bodies or just in parts.
Convergent evolution occurs in different phylogenetic branches independently from each other. It results from the need for different organisms to adapt to a similar environment and to solve a problem from that particular ecological niche. Ecological pressures acting on them might be similar, modeling the organisms´ phenotype. Each evolutive branch ends by developing the same structures, which they both find effective in their environment.
In the given cladogram, the trait that evolved twice in evolution is bipedalism, reflecting the same need for chickens and humans to adapt to their environment in the same way and according to their habits.

Explain the role of insulin in the homeostatic regulation of blood glucose levels
Answers
Answer:
Insulin helps the cells absorb glucose, reducing blood sugar and providing the cells with glucose for energy. When blood sugar levels are too low, the pancreas releases glucagon. Glucagon instructs the liver to release stored glucose, which causes blood sugar to rise.

Explain the reason the Type AB and Type O blood phenotypes always have the same
genotype, whereas the Type A and Type B blood phenotypes have two possible allelic
combinations.
Answers
Answer:
Because A is co-dominant to B and O is recessive, so the genotype is the same as the phenotype. But A can have 2 genotypes because A can mask a recessive allele, which makes the phenotype A. B can also mask a recessive allele, which makes the phenotype B.
Examples
AO (genotype) = A (phenotype)
BO (genotype) = B (phenotype)

O D. Phenol-chloroform extraction
Answers
Answer:
The correct answer is - C. Chelex extraction.
Explanation:
Chelex extraction is a DNA extraction method that involves a Chelex100 chelating resin that prevents DNA degradation by traping the degradative enzymes and from potential contaminants.
In absence of this Chelex resin, a styrene polymer resin that binds metal ions that might inhibit downstream analyses. This process involves a commercially used Chelex 100 which is a styrene-divinylbenzene copolymer that has paired iminodiacetate ions, which act as chelating groups in binds metal ions.

Agriculture is the leading source of pollution in many countries. Pesticides, fertilizers, and other toxic farm chemicals can poison fresh water, marine ecosystems, air, and soil. They also can remain in the environment for generations.
What are the major environmental problems caused by agriculture?Agriculture contributes to a number larger of environmental problems that cause environmental degradation including climate change, deforestation, biodiversity loss, dead zones, genetic engineering, irrigation problems, pollutants, soil degradation, and waste.
Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water.
Fossil fuels began to be used, which led to increased pollution, and the construction of factories led to the loss of habitat for many wild animals. The development of agriculture has led to the emergence of new plant varieties, domestication of animals, and disturbance of soil composition.
Therefore, some of the environmental problems caused by the agriculture and natural resource industry are well described above.
