Yay Sachs disease is a disorder characterized by an accumulation of fatty substances called gangliosides in the brain and spinal

cord. One cause of the diseas is a mutation in the gene sequence that codes for the enzyme hexosaminidase A. The enzyme is rendered nonfunctional when a single amino acid is incorporated into the enzyme instead of an arginine. In this scenario, what is the cause of tay-Sachs disease

Theodor W. Engelmann illuminated a filament of algae with light that passed through a prism, thus exposing different segments of
WARRIOR [948]

Answer:

The correct answer is C and Engelmann conducted this experiment to prove relationship between algae and the rate of photosynthesis.

Explanation: First we must talk about 3 facts:

1) Prism scatters the white light into different wavelengths.

2) Photosynthesis, 6 carbon dioxide and 6 water molecules are consumed and 6 oxygen and 1 sugar molecule is synthesized using light energy.

6CO2 + 6H2O → C6H12O6 + 6O2

3) Aerobic bacteria breaks down sugar while using oxygen and produces water and carbon dioxide in simplified terms.

So with this experimental setup a researcher can understand the rate of the photosynthesis by increased accumulation of aerobic bacteria near algae  in certain wavelengths since they uses oxygen and tend to move close to the oxygen source (<u>see figure</u>). In this experiment there are no ways to measure heat (B), there is no known relation between wavelength of light and aerobic respiration since it can happen even in the dark (A) and finally there are no ways to measure carbon dioxide (D).

Select the correct statement about double fertilization in the angiosperm life cycle. a. Double fertilization results from the f
erastovalidia [21]

Answer:

Double fertilization produces a diploid sporophyte and a triploid endosperm. (Ans. C)

Explanation:

Angiosperm are plants which is known for flowering plant on the earth. The flower is reproductive parts of the angiosperm plant. They are including 4 basic parts of the flower: Carpel, Stamens, Sepals and Petals.

During angiosperm plant reproduction, 2 structure are formed which are known as the Endosperm and a Zygote. Later a Zygote will grow and form a embryo and the endosperm is known for food source of plant embryo. Endosperm and Zygote forming process is known as double fertilization and it is a unique process found in angiosperms.

Steps involved in double fertilization are:

1) The pollen tube processing to release 2 sperm cells into an unfertilized ovule.

2) When one sperm cell fuses with the eggs to the formation of zygote and another sperm fuses with the 2 polar nuclei to the formation of endosperm this process is known as double fertilization.

3) After the completion of double fertilization, a fruit and seed develop.
