Answer: D) autotrophic nutrition

Explanation: Autotrophic nutrition is a type of nutrition in which a living organism manufacture its own food. For example, plants are autotrophs and they manufacture their own food using chlorophyll present in plant leaves to trap sunlight in the presence of carbon dioxide and water. This process is known as photosynthesis. In photosynthesis, plants use chlorophyll (a green pigment found in the Chloroplast of plant cells) to trap energy from the sun, in the presence of water and carbon dioxide to produce glucose and oxygen. The balanced chemical equation for photosynthesis is 6CO2 + 6H2O + solar energy --> C6H12O6 + 6O2.

It is hotter near the equator because the Sun's rays hit the Earth more directly in that area so they are focused or concentrated more in that area

Round seeds and yellow seed color are dominant to wrinkled seeds and green seed color. What is the probability of having offspri

Reika [66]

Answer:

Explanation:

This question involves two distinct genes; one coding for seed shape and the other for seed colour. The allele for you seeds (R) is dominant over the allele for wrinkled seeds (r) in the first gene while the allele for yellow seeds (Y) is dominant over allele for green seeds (y).

In a cross involving RRYY (homozygous dominant for both traits) and RrYy (heterozygous for both genes), the following allelic combinations of gametes will be produced:

RRYY- RY, RY, RY, RY

RrYy- RY, Ry, rY, ry

Using these gametes in a punnet square (see attached image), 16 possible offsprings will be produced. The genotypes of the offsprings in the ratio 1:1:1:1 will be:

RRYY (4)

RRYy (4)

RrYY (4)

RrYy (4)

According to the question, offspring that have wrinkled seeds and yellow seed color will have genotype: rrYY or rrYy.

This genotype is not one of those that will be produced by the cross between a RRYY and RrYy parent. Hence, the probability of having an offspring with wrinkled seeds and yellow seed color is 0%

Some of the stars you see in the night sky are already gone. Why is it possible to still see their light?

AlladinOne [14]

Answer:

they are light years away

Explanation:

when you look at the sky you are looking at about 6 million years in the past because time travels differently between space and our atmosphere. That's why astronauts can feel like they have been gone for 3 days but really for 3 months.

Key point:

Light travels differently between space and Earth
