Answer:
Some amino acids are encoded by more than one codon, inasmuch as there are 64 possible base triplets and only 20 amino acids. In fact, 61 of the 64 possible triplets specify particular amino acids and 3 triplets (called stop codons) designate the termination of translation.
During the late Precambrian era, enough

period of
global warming.
Answer:
Eventually, enough CO2 escaped from volcanoes to begin a period of global warming; melting opened a great variety of new niches. When CO2 levels were high, they created a greenhouse effect. More heat was trapped on Earth's surface, and the climate became warmer.

Which of the following characteristics of a population will make it better able to adapt to environmental changes?
A.Rapid production of many offspring.
B.Specialization in one type of food source.
C.Large amount of inherited genetic variation.
D.Isolation to a limited geographic range.
Answer:
C
Explanation:
Answer: C. Large amount of inherited genetic variation.
If you had a population where the genetic variation wasn't as high or practically non-existent, then that population is likely suited to that very narrow specific environment. If the environment doesn't change, then the population wouldn't have a problem. However, the environment isn't likely to stay static. Things change all the time and this change will bring challenges to the population that was suited for the old environmental conditions.
Populations with high genetic variability will have some individuals thrive while some unfortunate members will perish. The members that die off are likely the ones who cannot adapt to the changes. As the environment changes, the individuals who survive will pass on their DNA to their offspring, allowing for natural selection to reinforce those favorable traits. Since the environment is constantly changing, whether that change is slow or fast, this means the process is continued indefinitely. So that's why high genetic variability is favored.

What are some methods that predators use to capture prey?
Answer:
Offensive Strategies of Predators
Cheetahs use speed to outrun their prey, and eagles, hawks, owls and falcons use flight to their advantage while hunting. Venomous snakes, spiders and wasps use poisons to either kill or immobilize their prey. Some predators even use mimicry to capture prey.
A young man recently learned from a genetics doctor that he had a condition called Friedreich's ataxia. This syndrome affects the arms and the legs with the person usually needing a wheel chair. Neither of his parents have this disorder. However the young man's grandfather was wheelchair bound, but didn't know why because genetic information was very limited when his grandfather grew up. Based on this information, what type of inheritance does Friedreich's ataxia follow? Explain why. What are the genotypes of each of the individuals mentioned in this question? Create a pedigree chart to support your answer.
Answer: Friedreich ataxia is a genetic condition that affects the nervous system and causes movement problems. People with this condition develop impaired muscle coordination (ataxia) that worsens over time. Other features of this condition include the gradual loss of strength and sensation in the arms and legs; muscle stiffness (spasticity); and impaired speech, hearing, and vision. Individuals with Friedreich ataxia often have a form of heart disease called hypertrophic cardiomyopathy, which enlarges and weakens the heart muscle and can be life-threatening. Some affected individuals develop diabetes or an abnormal curvature of the spine (scoliosis).
Most people with Friedreich ataxia begin to experience the signs and symptoms of the disorder between ages 5 and 15. Poor coordination and balance are often the first noticeable features. Affected individuals typically require the use of a wheelchair about 10 years after signs and symptoms appear.
About 25 percent of people with Friedreich ataxia have an atypical form in which signs and symptoms begin after age 25. Affected individuals who develop Friedreich ataxia between ages 26 and 39 are considered to have late-onset Friedreich ataxia (LOFA). When the signs and symptoms begin after age 40 the condition is called very late-onset Friedreich ataxia (VLOFA). LOFA and VLOFA usually progress more slowly than typical Friedreich ataxia.
The genotype of the grandfather and the young man is ff (f allele for Friedreich's ataxia) The genotype of the father and the mother is Ff.
What is a genotype?A genotype is a classification of the type of variant found at a certain position (i.e., a locus) in the genome. Symbols can be used to symbolize it.
Friedreich ataxia is a hereditary disorder that causes movement issues by affecting the neurological system. This disorder causes decreased muscular coordination (ataxia), which worsens over time.
Individuals with Friedreich ataxia frequently have hypertrophic cardiomyopathy, a type of cardiac disease that enlarges and weakens the heart muscle and can be fatal. Some people who are impacted have diabetes or an irregular spine curvature (scoliosis).
Therefore, the genotype of the grandfather and the young man is ff (f allele for Friedreich's ataxia) The genotype of the father and the mother is Ff.

Explanation:
Cross two heterozygous black mice and tell the possible phenotypes and
genotypes in their offspring.
Answer:
The correct answer is -
Phenotype: 3:1 (dominant black mice: recessive brown allele)
genotype: 1:2:1 (purebred dominant : heterozygous: purebred recessive)
Explanation:
In the given question there is a cross that takes place between two heterozygous black mice. LEt assumes B is black which is the dominant allele and b is the recessive allele or brown. As it is given in heterozygous condition black mice are present which means the B is dominant over b.
Now cross:
Gametes: B and b for each mice
B b
B BB Bb
b Bb bb
By the cross, there are two phenotypic offspring that produce 3 black mice out of four and 1 brown or recessive allele out of four
And, genotypically three offspring in the ratio of 1:2:1 (purebred dominant : heterozygous: purebred recessive)

How can we tell histologically that skeletal muscle tissue is highly vascular?
Answer:Muscle tissue is composed of cells specialized for contraction. Muscle is classified into three types according to their structure and function:
Skeletal muscle cells - striated, voluntary control
Cardiac muscle cells - striated, involuntary control
Smooth muscle cells - nonstriated, involuntary control
Skeletal and cardiac muscle cells are called striated because they show an alternating series of bands. The repeating arrangement of their basic contractile unit, the sacromere, produces these striations.
In all types of muscle, contraction is caused by the movement of myosin filaments along actin filaments.
The terms muscle cell and muscle fiber are synonymous.

Predict one possible problem with a DNA molecules' structure that could occur.
Answer: DNA damage due to environmental factors
Explanation:
DNA is a genetic material present in the cell of living organisms. The DNA can be damaged by the environmental factors which can induce mutations in the structure of the DNA further affecting the function. The environmental factors like ultraviolet rays, chemicals, ionizing radiation can damage the structure of the DNA. For example, the chemical may contain alkylating agents which can cause the hydrolysis of the chemical bonds in the DNA.
