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.

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.

Explanation:

The marine fish of the family Scorpaenidae are the most venomous fish in the world. Three main genera provoke the majority of envenomations in humans: Synanceja (stonefish) (Fig. 36-50), Pterois (lionfish) and Scorpaena (true scorpionfish) (Fig.

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.

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.

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)

Muscular system is an organ system, Body performs all the kind of movements with the help of muscular system. Almost all the animals have muscles. The muscular system is composed of specialized cells called muscle fibers. Their predominant function is contractibility. Muscles are attached to bones or internal organs and blood vessels. There are more than 600 muscles present in a human body.

[tex]\Large\textbf{Types of Muscles:}[/tex]

There are three types of muscles in a vertebrate body. They are

[tex]\Huge\text{Smooth Muscles}[/tex]

Smooth muscles are structurally the simplest of all muscles types. They are non-striated, and consist of long spindle shaped uni-nucleated muscle cells that are usually arranged in sheets that surround the body's hollow organs. Smooth muscles are also involuntary in action. Smooth muscles push the food through the digestive tract, they empty your urinary bladder, they control the diameter of the blood vessels, the diameter of your eye, the state of erection of hair of the skin, and the smooth muscles form the layer of sheet  around all the visceral organs.

Non-striated muscles, this means that muscles do not have transverse light and dark bands. The striations are caused by the regular arrangement of contractile proteins (actin and myosin). Actin is a globular contractile protein that interacts with myosin for muscle contraction. This means that non-striated muscles can not contract, thus they can not move.

Uni-nucleated Muscles, Smooth muscles are the only muscles which have cells with only one nuclei.

Involuntary in action, This means that their contraction is not under the control of somatic nervous system. The involuntary muscles are automatically controlled by the autonomic nervous system controls the activities of the inner visceral organs (heart, glands, smooth muscles), while the somatic nervous system controls all the voluntary actions.

Visceral Organs, word Visceral arises from latin word Viscera which means "the organ of the body", So Visceral organs are all the internal organs of the body, specifically those within the chest and abdomen. They are covered with visceral membrane made of smooth muscles.

I have attached two pictures of the smooth muscles, one is colored and the other one is colored and the other one is diagrammatic.

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.
