Answer:

The beginning and majority of the time is known as Interphase. Interphase is 80% of the total cycle and is where the cell does most of the work in replicating organelles, chromosomes, and preparing to undergo Mitosis which is the actual splitting process where one cell becomes two. During Interphase there are 3 major steps, G1, S, and the G2 phase.

Thepotemich [5.8K]

Answer:

1.To prepare compost, either a plastic or a concrete tank can be used. The size of the tank depends upon the availability of raw materials.

Collect the biomass and place it under the sun for about 8-12 days. Now chop it to the required size using the cutter.Prepare a cow dung slurry and sprinkle it on the heap for quick decomposition.Add a layer (2 – 3 inch) of soil or sand at the bottom of the tank.Now prepare fine bedding by adding partially decomposed cow dung, dried leaves and other biodegradable wastes collected from fields and kitchen. Distribute them evenly on the sand layer.Continue adding both the chopped bio-waste and partially decomposed cow dung layer-wise into the tank up to a depth of 0.5-1.0 ft.After adding all the bio-wastes, release the earthworm species over the mixture and cover the compost mixture with dry straw or gunny bags.Sprinkle water on a regular basis to maintain the moisture content of the compost.Cover the tank with a thatch roof to prevent the entry of ants, lizards, mouse, snakes, etc. and protect the compost from rainwater and direct sunshine.Have a frequent check to avoid the compost from overheating. Maintain proper moisture and temperature.

B is wrong because water contamination does not directly relate to respiratory health.

D is wrong because fertilizers can impact respiratory health (Explanation seems lack-luster, but I feel like this is common sense).

Hope this helps :)

The brown-eye allele is dominant over blue-eye allele. A couple currently has 3 children with brown eyes. What is the probabilit
MissTica

Answer:

The correct answer is: 25 %

Explanation:

According to Mandel's law of inheritance, the dominant allele masks the expression of the recessive allele if present together. If a couple has 3 children with brown eyes. In a monohybrid cross, the ideal phenotypic ratio of the offsprings is 3: 1 or in other words, the dominant character chances to appear is 75% in phenotype.

So, by the law of dominance of monohybrid cross the chances of the fourth child to develop blue eyes is 25%.

Thus, the correct answer is : 25 %.
