What type of microscope is used when Determining whether a tissue type is
human, plant, or animal

Answers

Answer:

compound microscope

Explanation:

they are illuminated and the image seen with this type of microscope is two-dimensional. this microscope is the most commonly used this microscope is the most commonly used you can view individual cells even living ones

Answer:

The Compound Microscope.

Explanation:

You would use this microscope because you are examining and analyzing a tissue sample and are trying to determine if its human, plant or animal. The compound microscope enlarges things to make them look bigger. So you would use this because you would be able to see the tissue sample more clearly and bigger and then all you have to do is look to see if that would be human, plant, or animal.

Farmers have selected for increased oil content from corn. For a long time, the plants responded with steadily increasing oil content, but recently the response slowed and then stopped. When this line of corn is crossed to another line and the hybrids are selected, the oil content resumed its climb. What is a plausible reason for the lack of response?
A. The environmental conditions improved.
B. The genetic variation for the trait was exhausted.
C. There was too much genetic variation for the trait.
D. The environmental conditions deteriorated.
E. Artificial selection is different than natural selection.

Answers

Answer:

B. The genetic variation for the trait was exhausted.

Explanation:

Oil content is a quantitative trait, ie., a phenotypic feature that depends on the accumulative effects of many genes and the interaction of a genotype with its environment. During crop improvement, the plants (i.e., lines) containing desired alleles involved in the variation of this trait will be selected, thereby increasing oil content but simultaneously decreasing the genetic variation of the population. In consequence, after successive rounds of artificial selection, lines will not have sufficient genetic diversity to be again selected for this trait.

In muscle tissue, what is the reactant of lactic acid fermentation and the product that builds up during intense exercise?

Answers

The reactant of lactic acid fermentation and the product that builds up during intense exercise is glucose.

Homolactic Fermentation in Muscle CellsLactic acid fermentation is a metabolic process by which glucose or other six-carbon sugars are converted into cellular energy and the metabolite lactate, which is lactic acid in solution. Glucose is the simple sugar reactant used in this type of homolactic fermentation, instead of lactose used in the case of bacteria. This process of energy production is employed by muscle cells when oxygen levels are low, such as during periods of extreme exercise.

Which of the following base pairs would be found in a cell

Answers

adenine, thymine, guanine, and cytosine

adenine forming a base pair with thymine, and cytosine forming a base pair with guanine.

The base pair cytosine and guanine is found in the cell. The correct option is D.

What are base pairs?

A base pair is a primary component of double-stranded nucleic acids that comprises two nucleobases that are hydrogen-bonded to one another.

They are the foundations of the DNA double helix and make a contribution to both DNA and RNA's folded structure.

Purines and pyrimidines are nitrogen bases that form hydrogen bonds between DNA strands.

Predicated by Chargaff's Rule, they associate together via complementary pairing A::T and G::C. The purines in DNA are the same as those in RNA: adenine and guanine.

The 2 significant pyrimidine bases in DNA are cytosine and thymine, which base pair with guanine and adenine. Uracil supplants thymine and base pairs to adenine in RNA.

Thus, the correct option is D.

Many of the plants in a grassland environment are specifically adapted to that habitat. The natural selection that led to this adaptation was a result of all
the following EXCEPT
populations of plants naturally exhibit variation
plants produce more offspring than can survive.
the available resources do not support all the plants,
related plant species share some genetic material.

Answers

Answer: hybridisation between related species is unlikely to contribute to adaptive speciation.

Explanation: any population has natural genetic variation. The available resources are insufficient for all plants (and conversely, not all offspring survive). Natural selection favours variations better suited to the conditions.

Although hybridisation is more common in plants than animals, and can lead to speciation, adaptive radiation from an ancestral species is the general response to environmental change, such as from rainforest to savanna. There is low probability of selective advantage from hybridisation of two ancestral species adapted to niches within the original habitat when the conditions in those niches changes significantly.

Answer:

The correct will be C: The available resources do not support all the plants.
