Answer:
B) The first and second answers are correct.
Explanation:
The law of Independent assortment is one of the four laws of Mendel which states that alleles located on the chromosomes segregate or assort independently of each other.
This means that whether they are present close to each other or they are present at a distance they can be passed on in the generation together but they will show their effect on the phenotype independent of each other.
The law was concluded form the result of the dihybrid cross which showed that although the two genes were controlling the trait each allele will show its effect independent of each other or like a monohybrid result.
Thus, Option-B is the correct answer.
Duodenum is indicated structures contains the glands which secrete an alkaline mucus that helps to neutralize the acidic chyme
The duodenum is first part of the small intestine. The main role of the duodenum is to complete the first phase of the digestion. In this section of the intestine, the food from the stomach is mixed with enzymes from the pancreas and bile from gallbladder.
It may be subdivided into four sections: the superior part, is descending part, is horizontal part and is ascending part. The superior part (first part, D1) lies in intraperitoneally and is also enlarged proximally (duodenal bulb

Answer:
The correct answer will be option-pollen.
Explanation:
The pollen are the male gametophyte which is produced in the seed plants.
The pollen produce male gametes after entering the female gametophyte. The male gametes fuse with the egg cell and form the embryo inside ovary which matures and forms seeds. The vascular seed plants lack these pollen but instead produces male gametes in gametangia which are replaced by the pollen in the seed plants.
Thus, option-pollen is the correct answer.
Answer:
Through the study of meteorites, their chemical composition of silicates—material made of silicon and oxygen. Others contain metal—nickel and iron. Knowing what the meteorite was composed of lets you know where it came from. Chondrites are composed of hardened lava - this is occurred at the beginning of the solar system (4.5 mya). Carbonaceous chondrites contain carbon and water which formed away from the sun.
Explanation:
Planting plants would increase how much carbon dioxide they can take in as a whole, reducing the amount of carbon dioxide that goes into the atmosphere and therefore counteracting/minimalising our affecting the carbon cycle.
