Answer:

The correct answer is option A "Duplication".

Explanation:

Chromosomal duplication is defined as a type of rearrangement of genetic material at which extra copies of a DNA fragment are created. In this case if a broken chromosomal fragment becomes reattached, this fragment will represent an extra copy, and therefore the resultant genetic material is considered a chromosomal duplication.

Answer:

Please find the detailed explanation below

Explanation:

A chromosome is thread-like material that carries the long strands of the genetic material (DNA), which in turn carries the gene. The chromosome is the found form of nuclear material in the nucleus.

Due to the long nature of the DNA molecule, they cannot fit into the cell. Hence, to ensure they fit, the cell wraps the DNA molecule around a set of protein called HISTONE proteins to form a NUCLEOSOME. Each nucleosome is made up of DNA coiled around a set of 8 proteins called HISTONE OCTAMER. The nucleosome structure becomes more compacted and further wound around the histone to form a CHROMATIN. This chromatin then undergoes condensation to form the visible CHROMOSOME structure.

Hospitalizations will be less if adequate food safety practices are adopted.

Adequate food safety practices lead to less hospitalizations in the society because most people hospitalize due to bad food habits and food poisoning. If we implement safety measures related to food then we can save ourselves from various diseases as well as prevent ourselves from going to the hospital so in my opinion hospitalizations will be less if sufficient food safety measures are adopted by the people.

Answer:

Natural selection

Explanation:

According to  Darwin's theory, natural selection is the process by which individuals better adapted to their environments have more chances to survive and reproduce, and thereby their descendants will be better represented in the next generation. This mechanism exploits the existence of natural variation among members in the population which is used to select those individuals that are better adapted (i.e., with a higher adaptive fitness) for their environments. Natural selection is a key mechanism of evolution by which species change across time.

Answer:

c) Organisms within a population vary, and all populations produce more offspring than can be supported by the environment, resulting in competition for survival within the population.

Explanation:

Darwin's theory was based on the evidence of natural selection and survival of the fittest.

Evidence of Darwin's theory were observed from the variation in the population which is supported by the environmental factor (natural selection) and these population than produce offspring, resulting in competition for survival within the population (survival for fittest).

Hence, the correct option is "c".

Answer:

The answer is below

Explanation:

The weight of trees is calculated using the equation:

[tex]W=b_o+b_1(D^2H)[/tex]

W is the tree weight in tons, D is the diameter of the tree in inches, H is the height of the tree in feet and [tex]b_o \ and\ b_1[/tex] are constants.

The circumference is given by:

Circumference = 2πr

Where r is the radius and 2r is the diameter

Therefore:

14 = 2(22/7)× r

14 = (22/7)×2r

2r= 14 × 7 / 22

Diameter = 2r = 4.455 inches

[tex]W=b_o+b_1(4.45^2*120)\\W = b_o+2381.643b_1\\Let\ us\ assume\ b_o = -35,b_1=1.9.\\Therefore\\W = -35+2381.643(1.9)\\W=4490 \ tons[/tex]

Answer: The founder effect

Explanation: The high incidence of polydactyl prevalent among the Amish population could be attributed to the a case of genetic drift called the founder effect. The founder effect occurs when a small population consisting of few people separate from a much large population, just like the Amish population separating from the larger American community. Due to the few composition or small size of the population, the genetic impact or influence on members of the population is usually higher than the effect on the larger population and leading to more rapid spread. The relatively small individuals which make up the Amish population compared to the larger American community is the reason why polydactyl hmis prevent within them and since theere are no newcomers, the trend will likely continue.

adaptation

Explanation:

Adaptation in Biology refers to the process whereby an organism adjust to its natural environment in order to increase its chance of survival or in other words, the organism becomes better suited to its natural habitat by possession of some adaptive features.

In this example, a white peppered moth with black spots initially possess these color combination in order to blend to its natural environment, which is the bark on beech trees. However, due to the burning of coal in Great Britain which caused many of the beech trees to be black, the peppered moths had to ADAPT to this change in environmental color by becoming all black in order to blend in with the new bark color.

Therefore, this is an example of ADAPTATION.

Rayleigh wave, surface acoustic waves called Rayleigh waves move along the surface of solids, hence option D is correct.

They are commonly employed in non-destructive testing to find flaws and can be created in materials in a variety of methods, as by a localized impact or by piezoelectric transduction.

These include what are known as Rayleigh waves. A Rayleigh wave's amplitude decreases with depth below the surface and becomes noticeably tiny at depths greater than a few wavelengths.

As a result, the disturbance is limited to a solid's surface layers. The motion experienced by the surface layers includes both transverse and longitudinal components.

Answer:

C. glycoproteins

Explanation:

Glycoproteins are proteins containing glycans (oligosaccharide carbohydrates) attached to amino acid side chains. These oligosaccharides are attached to the amino acid chain by a posttranslational modification referred to as glycosylation, a modification generally found in extracellular regions. Glycosylation refers to the chemical reaction in which a glycosyl donor (i.e., the carbohydrate) is attached to a functional group in the protein. The glycosylation sites play distinct functional roles for both cell interactions and cell recognition. Moreover, glycosylation sites are also essential for substrate recognition by an enzyme. For example, secreted cytokines are glycosylated, which is required for their binding to receptors.

Answer:

New leaves appear on a tree in spring. - NO

An amoeba divides in half. - YES

A bean plant produces seeds in long pods. - YES

Pollen grains are released from a flower. - YES

A sea star produces a new arm after losing one to a predator.​ - NO

Explanation:

The appearance of new leaves has nothing to do with reproduction but rather regeneration.

An amoeba dividing in half is a form of reproduction known as asexual. Binary fission is a reproductive process in which an organism divides into two and each half develops into new independent organisms.

A bean plant producing seed is part of the reproductive process. After fertilization, the ovule of a flower becomes the seed. A seed in itself is a ripened fertilized ovule.

The release of pollen grains from the anther of a flower to the stigma of a compatible flower in the same or different individuals plants is known as pollination. Pollination is a reproductive process similar to fertilization.

A sea star producing a new arm after losing one to a predator is a regeneration process rather than a reproductive process.
