Answer:
Yes, Mass Extinctions May Have Been Caused By Meteors, as the probability of mass extinction occurring after an asteroid that could hit a random location on the Earth's surface was approximately 13% when the Chicxulub-scale asteroid hit the Earth.
Soot could be the main cause of mass extinction after an asteroid impact.

In soil erosion, the soil is carried away from by the wind or water from the top layer of the ground. Soil formation is making soil. It can be by the deposition of the soil from water or wind
<h3><u>Turmeric powder can be adulterated in many different ways:</u></h3>
- Curcuma longa(Turmeric) is a strong base and is used as a domestic product.
<u>The possible adulteration and deterioration of Curcuma longa are as follows</u>:
- It can be mixed with chalk powder which results in production of small bubbles.
- When turmeric powder is mixed with water, it produces some streaks of soluble colour in water that is caused as a result of adulteration of lead chromate in turmeric powder.
Answer:
The genotype of both parents is RrYy.
The possible types of gametes would be RY, Ry, rY, and ry.
The cross would produce offspring that can have one out of four types of phenotypes:
- Round and yellow seeds (1 RRYY+ 2 RrYY +2 RRYy + 4 RrYy) = 9/16
- Wrinkled and yellow seeds (3 rrYy) = 3/16
- Round and green seeds (1 RRyy + 2 Rryy) = 3/16
- Wrinkled and green seeds (rryy) = 1/16
Thus, one out of 16 offspring would have wrinkled and green seeds.
