Answer:
Galactose
Explanation:
Galactose is a sugar with six carbons and one aldehyde group present at the end. The presence of a free aldehyde group in galactose makes it a reducing sugar. Galactose can reduce the Cu2+ of Benedict solution into Cu+ and produce a red precipitate. Sorbitol, β-ethylglucoside, and gluconate do not have aldehyde group to reduce Cu2+ ions and therefore, do not give the positive test with Benedict solution.
b. dominant autosomal
c. x-linked
d. y-linked
e. either x or y-linked
Answer:
The correct answer will be option-A
Explanation:
In the pedigree analysis, the description of a trait help shows the relation of a trait linked to a gene.
The pedigree analysis is usually used to determine the heredity of a disease in a family which has been described in the question also as
1. The trait is rare and present in both sexes- this shows that it is independent of sex chromosomes and since is rare is recessive.
2. A consanguineous mating- mating between close relative which result in autosomal recessive trait as the genes for the trait must be present on both the parents which happen only when they are closely related.
Thus, option-A is the correct answer.

Answer:
there are diffrent type of emperor penguins so they are considered a species
Explanation:
Answer:
False.
Explanation:
NADP does not convert testosterone to estradiol. This oxidation is done by a steroid 17-a-hydroxysteroid dehydrogenase.
This oxidation is essential for stability of hormone: it helps to regulates the elevation of Testosterone in women,subduing the manifestation of male sexual characteristics,
and
for preventing autoimmune diseases.
The oxidation involved two basic steps of reaction, controlled by two different enzymes.
NADP is a Co- factor, when in reduced form( NADPH) is used in Calvin cycle, of light independent reaction of photosynthesis, and in Nucleic acid and triglycerides synthesis.
It has nothing to do with conversation of Androgen( testosterone to Estradiol.

Hope that helps!
It consists of different layers of different thicknesses.
It allows visible light to pass through completely.
It contains gases that filter out ultraviolet radiation.
2. Matthew has recently learned that Earth’s atmosphere is made up of nitrogen, oxygen, water vapor, and many other trace elements. Which of the following is NOT a way in which gases in the atmosphere are helpful to life on Earth?
Carbon dioxide insulates Earth
Protection against radiation from the Sun
Barrier against violent storms and lightning
Oxygen stays within the atmosphere
3. Which of the following is a way the atmosphere helps maintain life on Earth?
The atmosphere helps maintain a moderate temperature.
The atmosphere draws water vapor from outer space.
The atmosphere has air currents that rotate the planet.
The atmosphere contains some gases that are toxic.
keep her skin protected. She wonders what else the atmosphere does that she takes for granted each day. The atmosphere allows which of the following to happen?
Meteorites to hit Earth’s surface
Chloroplasts producing oxygen
Reflection from the ocean's surface
Precipitation and the water cycle
5. Gases in the atmosphere are helpful to life on Earth because they offer protection from which of the following?
Poisonous gases from stars
Harmful radiation from the Sun
Collisions with other planets
Violent storms and lightning
6. Without the atmosphere, life on Earth would not be possible. Which of the following is NOT an explanation for how Earth’s atmosphere protects life on the planet?
It allows visible light to pass through completely.
It contains gases that filter out ultraviolet radiation.
It keeps Earth warm by trapping in heat.
It protects life from ultraviolet rays of light.
7. Alexander applies sunscreen to help provide protection from ultraviolet radiation. With what does the atmosphere provide protection for Earth?
Thick layers of ice clouds
Ozone in the upper atmosphere
Water vapor in the lower atmosphere
The reflective surface of the ocean
8. The atmosphere is often referred to as a blanket that covers Earth, keeping out harmful things and protecting life inside. Which of the following best represents a way in which the atmosphere helps maintain life on Earth?
The atmosphere provides air for oxygen.
The atmosphere controls the distance from the Sun.
The atmosphere helps rotate the planet.
The atmosphere provides protection from disease.
9. Which two gases in the atmosphere are essential to life on Earth?
Nitrogen and helium
Carbon dioxide and oxygen
Neon and argon
Helium and hydrogen
10. The atmosphere is made up of four different layers: the thermosphere, mesosphere, stratosphere, and troposphere. Which of the following is NOT true regarding the composition and structure of the the atmosphere?
The structure maintains safety against harmful UV rays.
The composition allows necessary gases for life on Earth.
The atmosphere allows Earth to rotate around the Sun.
The atmosphere is made up of nitrogen, oxygen, and a variety of gases.
Earth's atmosphere contains gases that filter out ultraviolet radiation. So, the correct options for 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10 are D, A, A, D, B, A, B, A, B and C respectively.
The layer of gases that covers the Earth is known as the atmosphere. It is made up of roughly 78% nitrogen, 21% oxygen, and 1% additional gases like argon, carbon dioxide, neon, and methane. It is held in place by the gravity of the Earth. The troposphere, stratosphere, mesosphere, and thermosphere are the four principal layers of the atmosphere.
Gases in the atmosphere of Earth serve as UV radiation filters. CO2 acts as an insulator. The existence of life on Earth is not a result of atmospheric gases. A temperate temperature is kept by the atmosphere. The water cycle and precipitation are made possible by the atmosphere. Life on Earth benefits from gases in the atmosphere because they provide protection from harmful solar radiation.
Earth is protected by ozone in the upper atmosphere. The best way to think about how the atmosphere supports life on Earth is as the source of oxygen in the air. The atmosphere's carbon dioxide and oxygen are necessary for life on Earth.
So, the correct options for 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10 are D, A, A, D, B, A, B, A, B and C respectively.
