What does the study of embryology tell us about evolution?

Answers

Answer 1

Answer:Embryology, the study of the development of the anatomy of an organism to its adult form, provides evidence for evolution as embryo formation in widely-divergent groups of organisms tends to be conserved. ... Another form of evidence of evolution is the convergence of form in organisms that share similar environments.

Niagara Falls is a big waterfall on the border of Canada and the United States. Each year the edge of the waterfall moves back a couple of centimeters because the water is breaking apart the rocks on the edge. What is this an example of? Why?

Answers

This is an example of erosion. Erosion is when something is “washed” away (or eroded) over time (usually by water). The rocks are breaking apart because the rushing water is slowly eroding the edge a couple of centimeters every year.

What part of the cell determines the type and order of the amino acids that make up a protein?

Answers

Answer:

The gene, or sequence of DNA, ultimately determines the unique sequence of amino acids in each peptide chain. A change in nucleotide sequence of the gene's coding region may lead to a different amino acid being added to the growing polypeptide chain, causing a change in protein structure and therefore function.

If a red-eye female fly is crossed with a red-eye male fly, could they produce offspring with white eyes? Briefly explain your answer. Your answer must include a Punnett square that proves your answer.

Answers

If the red-eye parents are homozygous, no. But if the red-eye parents are heterozygous, yes.

Monohybrid crossing

We are assuming that the red-eye trait is dominant over the white-eye trait. If two red-eye parents are crossed with one another, whether they could produce white-eye offspring would depend on the zygosity level of the parents.

Assuming that red-eye is R and white-eye is r. If the two parents are homozygous red-eyed, their genotypes would be RR. Crossing the two:

       RR    x     RR

   RR   RR   RR   RR

All the offsprings would be RR and there is a zero chance of producing a white-eye offspring.

Now, assuming that the two parents are heterozygous:

        Rr    x    Rr

     RR   Rr   Rr   rr

Both RR and Rr are red-eyed while rr is white-eyed. The Punnet's square for the cross can be found in the attached image.

In other words, it will only be possible for the two red-eye parents to produce white-eye offspring if they are both heterozygous. Any other genotype will give a zero chance of white-eye offspring.

Why are Canada’s Evergreen Forests considered “Earth’s Northern Lungs”? (think about the photosynthesis equation)

Answers

Answer:

Although trees have responded to global warming in the past‐ to temperatures higher than they are now- the rate of change predicted in the 21st century is likely to be unprecedented. Greenhouse gas emissions could cause a 3°-6°C increase in mean land surface temperature at high temperatures and temperatures latitudes. Despite this, few experiments have isolated the effects of temperature for this scenario on trees and forests. This review focuses on tree and forest responses at boreal and temperate latitudes, ranging from the cellular to the ecosystem level. Adaptation to varying temperatures revolves around the trade- off between utilizing the full growing season and minimizing frost damage through proper timing of hardening in autumn and dehardening in spring.

Answer:

The moon's gravitational pull on the Earth is the main cause of the rise and fall of ocean tides. The moon's gravitational pull causes two bulges of water on the Earth's oceans—one where ocean waters face the moon and the pull is strongest and one where ocean waters face away from the moon and the pull is weakest.

Which letter marks the zone of inhibition?

Answers

Answer:

A. B

Explanation:

"B" as labelled in the above is the zone of inhibition.

The Zone of Inhibition is actually a test which is used to assess antimicrobial activities of a material or solution in relation to an micro-organism as a target. It is also known as Kirby-Bauer Test. It measures the antibiotic resistance and also used to inhibit microbial growth.

At the Point B, microbes can not grow in there; they are inhibited.

In the test, if bacterial strain or any other strain is susceptible to the antimicrobial agent, a zone of inhibition appears. If it shows resistance to that agent, then no zone is evidential.

A. Proteins
B. Carbohydrates
C. Lipids
D. Nucleic acids

Answers

Answer:

proteins create enzymes which speed up reaction

Enzymes are the molecules that catalyze biological reactions, while a catalyst is a material that aids in the occurrence of a chemical reaction, hence option A is correct.    

How do enzymes catalyze chemical reactions?

The crucial function of decreasing the activation energy of chemical events inside the cell is carried out by the majority of enzymes, which are proteins.

Enzymes are biological catalysts that significantly speed up reaction rates and have the propensity to be particular about particular reactants and products, a substrate is a term for the reactant in an enzyme-catalyzed process.    

Proteins are called enzymes to catalyze biological reactions that would not occur without them. For chemical reactions like digestion and cellular metabolism, these enzymes are necessary.

Therefore, since enzymes are a specific type of protein that catalyzes chemical events inside cells, they are excellent therapeutic targets, hence option A is correct.

Today, girls typically begin around age 12. This trend has been attributed to the growing number of overweight children and a greater exposure to pollutants. Exposure to phthalates, artificial chemicals found in plastics, has also been cited as a cause. These chemicals disrupt the endocrine system by mimicking hormones in the body.Early puberty can have many negative side effects, including an increased risk of certain types of cancer, such as breast cancer.
