Genes are composed of hereditary material. Identify this hereditary material

Answer: The answer is 4

Explanation:

Vitamin D controls your skin pigment. It's kind of like when someone has an iron deficiency they get bruises and they turn a whiter shade.

Hope I helped :)

The factors that were determined to directly cause the loss of skin pigmentation in humans as a result of natural selection are the impact of UV radiation on folate and Vitamin D levels in human populations.

 Ultraviolet B radiation produces diet D in human skin. Ultraviolet radiation can, however, smash folate. Folate is critical for the speedy increase of cells, particularly at some point in which its deficiency can motivate neural tube defects. The human frame additionally has a mechanism to save you overproduction of vitamins.

Ultraviolet is a shape of electromagnetic radiation with a wavelength from 10 nm to four hundred nm, shorter than that of seen light, but longer than X-rays. UV radiation is found in sunlight and constitutes approximately 10% of the whole electromagnetic radiation output from the Sun.

Thus it is learned that the above answers are well-explained factors that were determined to directly cause the loss of skin pigmentation in humans as a result of natural selection bout.

Answer:

Heredity is important to all living organisms as it determines which traits are passed from parent to child. Successful traits are more frequently passed along and over time can change a species. Changes in traits can allow organisms to adapt to specific environments for better rates of survival.

Answer:

The performers are consenting to being seen by the audience.

Explanation:

A voyeurist experiences pleasure from observing someone else having sexual relations, undressing, or performing any sexual activity. The voyeurist does not have the person's consent to watch, and they find ways to do it from a distance or with discrepancy. Part of their pleasure is from observing the person without consent, and another part is from observing the person engage in sexual activities. They do not desire to be in a sexual relationship with the observed person; they want to watch.

People who go to strip clubs do not observe from afar and hiding from the performer. They have the consent of the performers, which is the opposite of what attracts a voyeurist.

Answer:

14.284

Explanation:

Know parameters from the problem are: the amount of the substance/ gas molecule is 1.20 mol, the Temperature of the gas is 17 Celsius degrees (i.e. 290.15 K [17 Celsius degrees plus 273.15 K]), the pressure exerted on the container by the gas is 2.0 atm.

The unknown ( what you are asked to find) is the volume that the gas would occupy in its container under those conditions above; V=?.

We use the ideal gas equation here; PV=nRT. R in this equation is called the molar gas constant or Ideal has constant. There are many values for R given different circumstances. For the condition of this problem, R's value is 0.08205 L atm/mol K.

Make V the mathematical subject of the equation PV=nRT.

V=(nRT)/P

V=(1.20 mol x 0.08205 L atm per mol per K x 290.15 K)/ 2.0 arm

V= (28.568169 L atm mol per mol per K)/ 2.0 atm

V= 14.284 [(L atm mol K)/(atm mol K) atm mol K is in the numerator and the denominator would be canceled. Leaving only L.

Therefore, V= 14.284 L of N

Answer:

True

Explanation:

Microvilli: The cells on the villi are packed full of tiny hairlike structures called microvilli. This helps increase the surface of each individual cell, meaning that each cell can absorb more nutrients.

Answer: TRUE

Explanation: Villi are folds on the small intestine lining that increase the surface area to facilitate the absorption of nutrients. Absorptive cells that line the small intestine have microvilli, small projections that increase surface area and aid in the absorption of food.

So, the correct option is 'True'.

It would be 100 % pink.

Explanation:

Pink and Pink make Pink. Just as Red and White make Pink.

Due to incomplete dominance, when two pink flowered plants are crossed, the color of offspring could be 1Red: 2Pink :1White.

Hence, the offspring will be 1 Red flowered plant: 2 Pink flowered plant :1 White flowered plant.

The cell wall of gram-negative bacteria is thin (approximately only 10 nanometers in thickness), and is typically comprised of only two to five layers of peptidoglycan, depending on the growth stage. In gram-positive bacteria, the cell wall is much thicker (20 to 40 nanometers thick).

Answer:

Number of albino cockroaches = 486 cockroaches

Explanation:

Assuming that the population is in Hardy-Weinberg equilibrium and that albinism is recessive, the Hardy-Weinberg equation is used to determine the frequencies ofnthe different alleles in the population

According to the Hardy-Weinberg equation : p² + 2pq + q² = 1

Also p + q = 1

Where p² is the frequency of cockroaches having similar alleles for the dominant trait;

2pq is the frequency of individuals with the heterozygous allele, while q² is the frequency of the individuals having similar allele the recessive trait, albinism.

q² = 24/666

q² = 0.036

Since, the frequency of albinism in the population 0.036, number of individuals with the recessive allele, that is albino cockroaches in the next generation is obtained by multiplying the frequency with the number of individuals in the next generation.

Number of albino cockroaches = 0.036 × 13485

Number of albino cockroaches = 486 cockroaches

Answer:

Melanin

Explanation:

Melanin is the protective component of skin that defends us against UV light.

UV light poses big risks to our health, as it can damage DNA. DNA damage can lead to cancers like skin cancer.

Answer:

If there's a higher concentration of solutes outside of the cell (the solution is known as hypotonic solution) then the cell will swell up as the solutes will flow into the water through the process of osmosis. The cell may also swell up & burst (if it's an animal cell).
