Variations can be genetic or environmental, the traits are passed from one generation to other generation of snail is from from both parents to offspring and through the environment.

The correct answer is C.

Explanation:

Genetic variation in an organism is passed to the offspring by its parents.

environmental variation is the the result of different environment with which individual adapt.

Natural selection is a process in which a suitable trait which is well adapted to the environment is passed on tho future generations.

Genetic variation is the change in DNA or gene of the individual trait. The tree snails having different pattern in their shells is due to the habitat they are living in.

The snails which have well adapted to the environment are able to reproduce and pass on the traits to their progeny. The variation is due to the traits passed from parents through the environment also.

White meat contains less syoglobin than red meat. Red meat contains more ( slow-twitch / fast-twitch) muscles than white meat do
Nesterboy [21]

Answer:

Slow-twitch

Explanation:

Red meat is rich in slow-twitch muscle fibers. The slow-twitch muscle fibers are rich in myoglobin and blood capillaries. They also have many large mitochondria to generate ATP by aerobic respiration.

These fibers are slow-twitch fibers as the ATPase in myosin head carries out the hydrolysis of ATP at a slower rate causing a slower contraction cycle.

Slow-twitch fibers appear red due to a large amount of myoglobin and a rich network of blood vessels. They are capable of prolonged contractions and are fatigue resistant.

Natural and artificial selection depend on genetic and phenotypic variation. In natural selection, the selective pressure comes
otez555 [7]
<h2>B) option is correct </h2>

Explanation:

Natural selection is a selection pressure which operates in a population and allow the best fitted genotype to survive in changing environmental conditions and eliminate the other genotype which are not fit

In artificial selection, breeders select superior breed for the breeding purpose so that this type of selection favors the superior genotype and eliminates inferior genotype, thus leading to genetic drift

Stabilizing selection is a type of natural selection in which intermediate genotype is favored but extreme genotypes (inferior and superior) are eliminated

In the given example of pigmentation in pigeons, breeding is selectively done with intermediate pigmentation hence intermediate genotypes will be favored

Following knee replacement surgery 10 days earlier, an older adult client diagnosed with an infection in the knee has a synovial
Inga [223]

Answer:

<em>The correct option is B) Scientific paradigm</em>

Explanation:

The scientific paradigm focuses on the infection and the microorganism for the occurrence of the infection. A scientific paradigm also refers to the treatment of these infections through pharmaceutical or surgical approaches. Hence, option B is correct.

Other options, like option A, is not correct because a holistic paradigm focuses on the connection between the mind, body and the soul. Option C is false because the analytical paradigm is not a part of the major health belief system.
