Meiosis is a special type of cell division in sexually-reproducing organisms used to produce the gametes, such as sperm or egg cells.
Mendel accounted for the observation that traits that had disappeared in the F1 generation reappeared in the F2 generation by proposing that _____
A) new mutations were frequently generated in the F2 progeny, "reinventing" traits that had been lost in the F1
B) the mechanism controlling the appearance of traits was different between the F1 and the F2 plants
C) traits can be dominant or recessive, and the recessive traits were obscured by the dominant ones in the F1
D) members of the F1 generation had only one allele for each trait, but members of the F2 had two alleles for each trait
Answer:
C) traits can be dominant or recessive, and the recessive traits were obscured by the dominant ones in the F1
Explanation:
Mendel observed that the F1 generation obtained by crossing two pure breeding plants expressed only one trait. Here, the two parents differ from each other with respect to one genetic trait. F1 progeny expressed the phenotype identical to one parent plant while the trait expressed by the other parent plant was not present in the F1 progeny. However, the self crossing of two F1 plants obtained the F2 progeny and 1/4 F2 plants expressed the trait that was absent in the F1 progeny.
He concluded that the trait which was masked in the F1 was recessive and the alternating trait that appeared in the F1 was dominant. The presence of the allele for the dominant trait did not allow the expression of the allele for the recessive trait in the F1 generation.
Answer:
D. were socially isolated, unable to communicate with other monkeys, and incapable of caring for their young.
Explanation:
Attachment theory is an emotional bond that connect one person to another. Monkeys reared in Isolated Monkey have not been connected with other monkeys rared and have not experience how to get attached or care for the young. It has not been registered in their mind to act the way other do hence a difference between the Isolated and the reared once.
They will be socially distance from others also.

</span><span><span>Monosaccharide, disaccharides, and polysaccharides are the three major categories of molecules in Carbohydrates. </span>
Monosaccharides, known as simple sugar, is the simplest form of carbohydrates. Its basic molecular formula is CH2O. Monosaccharides are glucose, fructose, and galactose. Its primary function is to be the source of energy of living organisms. It is also the primary requirement for the formation of disaccharides and polysaccharides.
Disaccharides are formed when two monosaccharides are bonded together through a covalent bond. Common Dissaccharides are sucrose (glucose+fructose) or table sugar, maltose (glucose+glucose), and lactose (glucose+galactose). Its primary function is to provide nutrition for monosaccharides. Sugar in food is mostly dissaccharides.
<span>Polysaccharides are formed when another monosaccharides is bonded to the disaccharides. This bond is called glycosidic bond. Two major polysaccharides are starch and glycogen. Starch is made by plants while glycogen is made by animals. Polysaccharides' major function is to immediately release energy from its storage. When glucose is consumed, some of them are stored and will only be released when the body needs it to satisfy the body's immediate need of energy.</span> </span>
Answer:
Hydrogen Bonding
Explanation:
This attraction is called 'hydrogen bonding', and it operates between the hydrogen atoms on one H2O molecule and the oxygen atom of another. A hydrogen bond is a feeble link, a tenth the strength of the bond that holds the hydrogen and oxygen atoms of each individual molecule together.
