Within a population, the different colors and patterns of eyes are _____. A. the results of chance mutations B. reflections of the colors in the environment C. produced in anticipation of environmental forces D. created by the environmental effects on the phenotype
Answer: the correct option is B.
reflections of the colors in the environment
Explanation:
This is because the environment causes different reflections of color. Fir example white light reflect colors, it will absorb all other colors except with.
The environment serves a a medium for color reflection and this has lead to different color and patterns in population. People have eye pattern and color base on their surrondings, what the surronding is made off influence the color and patterns.
1. What percentage of puppies would have the same genotype as the
parents, Ww?
Answer:
50%
Explanation:
This question involves a single gene with two alleles W and w in puppies. According to the question, the genotype of the parent organisms are Ww. In a cross between the two parents i.e. Ww × Ww, the following gametes will be produced by each parent: W and w.
Using these gametes in a punnet square (see attached image), the following genotype of offsprings will be produced: WW, Ww, Ww, ww. Hence, based on this question, the percentage of puppies that would have the same genotype as the parents, Ww are 1/2 × 100% = 50%.

It helped to show that some bacteria can swim like fish.
It helped to show that some bacteria are just one cell.
It helped to show that cells can be created from thin air. shows the average wind speeds of four hurricanes in Florida.
Answer:
The correct answer is - option C.
Explanation:
Anton Leeuwenhoek observed the presence of organisms in his tooth scratch or scrapings under the primitive microscope made by himself. At that time there was no knowledge about the bacteria and he named these small creatures as animalcules. These animalcules were bacteria actually.
These creatures were single-cell organisms and able to perform the function as an entity and postulate that bacteria is a single which is a fundamental unit of function and structure of all living organisms.

On the first day after arriving in Miami for spring break vacation, Matt plays out in the sun for six hours. Later that night he notices that the skin on his legs and arms becomes red, swollen and extremely painful. By morning all of the afflicted areas have developed numerous blisters. These areas cover about 30% of his trunk (front and back) and 40% of the arms and legs.What organ has been damaged? What general types of tissue have been afflicted?What type of burn has Matt received? Explain.List ALL layers of the skin that have been damaged.What tissue repair process causes the blistering?List all of the body functions that may be disrupted by such a burn.After a few days his skin peels and the burned areas begin to heal. Matt notices that the healing areas are more susceptible to injuries due to chafing or trauma. During the next week after Matt returns to Tampa, Maria tells him that a sunburn prepares his skin for a deep tan. Maria encourages him to quickly begin tanning sessions at a local tanning salon before the effects of the burn wear off.What has happened to the skin that would cause this increased susceptibility?What would you advise him to do? Why?Is a deep tan a sign of skin that is healthy or severely stressed? Explain.

The question the scenario shows suggests, the integumentary system of Matt is affected, this system is part of the skin.
What is sunburn?A person having lesser melanin content in their skin has the risk of developing redness, swelling, and pain in the skin indicative of cellular damage caused by excessive sun UV radiation, this is known as sunburn.
Matt received a second-degree sunburn, which affects the dermal and epidermal layers of the skin. The inflammatory stage, proliferation stage, and matrix remodeling are the tissue repair process.
The skin is the first line of defence and acts as a barrier, after this injury affect this line of defence is affected causing entry of pathogens inside the body.
In absence of the epidermis, when the dermis is exposed, easily bruises and injury occur since blood vessels are exposed to the skin's surface.
Therefore, excessive exposure to the UV light creates deep tan signs.

Explanation:
A farmer is trying to increase the diversity of corn kernel color in his crops. The trait for corn color is controlled by two alleles. Yellow corn (B) is dominant over white corn (b). Which combination of corn should he cross to get the most variety of genotypes for corn color in the next generation?
A. BB x BB
B. Bb x bb
C. Bb x Bb
D. BB x bb
Answer:
C
Explanation:
If the farmer crosses Bb x Bb, then the progeny will have BB, Bb and bb genotypes attributing to increased diersity of corn kernel color in his crops.
What is a genotype?The total complement of an organism's hereditary material is referred to as its genotype. The alleles or variants that an individual carries in a specific gene or genetic region are also referred to as their genotype. Genotype is another term for them.
There are three distinct categories of genotypes: heterozygous recessive (pp), heterozygous dominant (PP), and homozygous recessive (pp). Both the dominant homozygous genotype and the dominant heterozygous genotype exhibit the same characteristics.
Therefore, if the farmer crosses Bb with Bb, the offspring will have BB, Bb, and bb genotypes, which will contribute to an enhanced diversity of corn kernel color in the farmer's harvests.

A strain of Drosophila known as dunce produces one-half the amount of cAMP phosphodiesterase found in wild-type flies, which causes a learning defect. Another strain of Drosophila known as rutabaga produces a defective adenylyl cyclase protein (one of the AC types expressed in most cells) and also causes a learning defect. A dunce - rutabaga double mutant fly has relatively normal learning. Explain these curious observations.
Answer:
From the given observations we can say that there are 2 genes that are responsible for normal learning. It is also given that the dunce and rutabaga mutations are the mutations of 2 different genes.
Due to complementation which is a phenomenon of restoration of normal phenotype if mutants are crossed, it is found that the flies have normal learning behavior if both mutants are crossed.
Let's assume that the Drosophila having this learning effect and it is due to genes D and R where D is the normal gene and dd is the case of mutation that results in duncy phenotype. Similarly, Gene R is responsible for normal learning, and rr results in rutabaga phenotype.
Cross between ddRR (duncy) x DDrr (rutabaga)
Gametes - dR x Dr
F1 progeny - DdRr
Thus, in heterozygous cases, a single copy of both wild-type alleles D and R complement each other.
All of the following are composed of body cells EXCEPT
a. bone

How are bees vital to our ecosystem? Describe what could happen if bees were to disappear from ecosystem Earth and what the consequences would be. In general, use WHO, WHAT, WHEN, WHERE, and WHY “are bees” DYING off. Lastly, how could We as humans integrate Bee hives efficiency in our own society?
Answer:
They are pollinators.
Explanation:
Bees are vital to our ecosystem because they are pollinators and due to this pollination, these bees are responsible for the presence of trees, shrubs and other small plants etc. if bees were to disappear from ecosystem Earth then the whole world is adversely affected because trees can't produces fruits and seeds so after sometime animals die due to unavailability of food. Human activities are responsible for the death of these bees because human activities causes pollution which is not good for bees. We have to make a safe place for bees and grow as many flowers as you can in order to increase their population.
If the anticodon of a molecule of tRNA has the sequence GAU, what was the original DNA sequence?
Answer:
CTA
Explanation:
DNA to RNa
A---> T
C--> G
RNa to dna
A--> U
C---> G
If the anticodon of one molecule of tRNA contains the sequence GAU, then CTA was the original DNA sequence.
What is DNA sequencing?
DNA sequencing is defined as the laboratory procedure used to determine the exact sequence or order of the four building blocks or bases that make up DNA. Information that is stored in DNA in a code which is formed by arranging the four bases which are adenine, cytosine, guanine and thymine which are identified by letters A, C, G and T in different order.
Within double-stranded DNA, nitrogenous bases on one strand pair with complementary bases on the other strand. A always pairs with T, and C always pairs with G, during DNA replication, the two strands separate into a double helix.
Sequence of tRNA is GAU, so the DNA sequence is CTA as C complements to G, A to T and U to A as in RNA Uracil is present in the place of thymine.
Thus, if the anticodon of one molecule of tRNA contains the sequence GAU, then CTA was the original DNA sequence.
