Mendel determined that for a given character(i.e. pea seed shape) an individual has two factors that these can exist in two form

s (R or r). Today we would describe R and r as being:______.
a. different alleles of the seed shape gene.
b. different genes of the seed shape locus.
c. different genotypes of the seed shape character.
d. different loci of the seed shape gene.

Answer:

a. different alleles of the seed shape gene.

Explanation:

Mendel crossed different varieties of pea plants and he observed how phenotypic traits passed to the progeny. From these experiments, Mendel formulated the 'First Law of Segregation', where he observed that traits may exist in pairs that segregate (separate) at meiosis. During meiosis, i.e., gamete formation, these two factors separate from each other, thereby each gamete has the same probability of receiving either factor. Nowadays, we know that these two factors represent two different gene variants or 'alleles' for a given gene <em>locus</em>. Alleles can be classified into dominant or recessive as in the example above described, where the R factor (round) dominates on the r factor (wrinkled) to determine the seed shape.

Called solar system because Sun is biggest and heaviest

Solar means sun  planets revolve about (travel in circles around) the sun  path a planet travels is called its orbit  earth is the 3rd closest planet to the sun  all the planets go around in the same direction (like clockwise or counterclockwise), in roughly the same plane, but at different speeds  planets close to sun move fast, far out move slower  closer a planet is to the sun, the hotter it is, more or less.

The above is only approximately correct scientifically, but could be good enough for grade school.  Look up "solar system" in wikipedia for more details and accuracy.

Explanation:

Hope this helps! :)

What happens to alleles between the p generation and the f2 generation?
ikadub [295]

<span>During the development of a gamete, the two alleles of the P generation separate.  Each gamete carries one allele from each parent which randomly pairs in the F1 generation. This mechanism repeats when F1 plants cross and yield F2 plants.  The outcome of the F2 generation would then have new combinations of alleles which can be different compared to the preceding generations.</span>

Which process most likely enabled the formation of the early protists?
sergejj [24]

Answer:

endosymbiosis.

Explanation:

By the beginning of the 20th century, researchers thought that plastids and mitochondria could come from bacteria. These would have been ingested by primitive cells and live within them in symbiosis.

I just need help understanding the question a bit more
mash [69]

Answer:

D

Explanation:

So basically genes are made of DNA molecules. DNA molecules are the building blocks of genes.... if you think about legos for a second the building blocks of legos would be plastic right? because without plastic you don't have legos which is same here... genes are legos and DNA molecules are the plastic that make them (if you get my analogy).

So genes are the information carriers because they carry information on how to make a certain protein or express certain characteristics. Gene directs the cell to make certain proteins and proteins are the key players that are involved in many cellular process because they carry out major functions hence, the protein determine the function of cell because without protein the cell would have no function
