Isotopes of uranium are the most common fuel used in nuclear power plants. True/ False

ruslelena [56]

This is true, they are a large unstable isotope that can be broken down into smaller more stable elements to release energy to power turbines and generate electricity

3. There is a gene that affects pea pod color and has two alleles: G = yellow and g = green. There is another gene that affects

Lena [83]

A. Mendel in his experiments used two true breeding plants that only express one particular trait. He would chose plants with different versions of the trait and cross pollinate them. So, in this case, Mendel’ s P generation would be:

P: GGWW x ggww

B. The possible gametes produced by these first or original parent plants (GGWW and ggww genotypes of the parents) are:

GW and gw. When an organism makes gametes, each gamete receives just one copy of the gene, which is selected randomly (Mendel’s law of segregation).

C. If the gametes GW and gw are joined, the genotype in the offspring would be GgWw. This is dihybrid organism because it is heterozygous (have two different allelss, one recessive, one dominant) at two different genetic loci, G and W. The offspring represents the F1 generation.

D. If the individuals with the genotype GgWw are crossed with the individuals with the same genotype (GgWw), the possible gametes are GW, Gw, gW, gw. The possible genotypes for the F2 generation are: GGWW, GGWw, GgWW, GgWw, GGww, Ggww, ggWW, ggWw and ggww. There are nine different genorypes. The genotypic ratio is 1:2:2:1:4:1:2:2:1.

E. F2 generation of offspring of this dihybrid cross has a 9:3:3:1 phenotype ratio. Mendel did similar experiment with his plants and conluded that the pairs of traits in the parental generation (P generation) sorted independently from one another, from one generation to the next.

List and describe three ways that bacteria can acquire new genetic material

OLga [1]

Answer:

The three most common ways that bacteria diversify their DNA are transformation, conjugation, and transduction. Genetic Material: the material in our cells that makes us who we are inside and out.

Deoxyribonucelic Acid (DNA): hereditary material found in the nucleus.

Ribonucleic Acid (RNA): genetic material that differs from DNA through its chemical bases.

DNA contains all the secrets that make you so awesome! So, it is super important that the cell keeps the DNA safe. DNA has so much information that it could stretch from the earth to the sun four times! No seriously, four times! I'm sure you're thinking, how does all that information get into something so small? Well, DNA is highly organized in order to keep all information safe, yet accessible to the cell. This is a great thing because you don't want to lose your awesomeness! DNA is comprised of four chemical bases also known as nucleotides: adenine (A), guanine (G), cytosine (C), and thymine (T). These bases pair with one another, A with T and C with G. Each base is attached to a sugar (ribose) and a phosphate molecule: hence the name deoxyribonucleic acid.

Now that we have the basic building blocks of DNA, let's get into the structure. DNA is double stranded, and each strand is held together by the pairing of the nucleotides. Remember what we mentioned above: A loves T and C loves G. These bases never cheat on one another; they only pair with the partner they love! The double stranded DNA is spirally coiled to form a helix. You will find many textbooks refer to DNA as a double helix. This double helix looks much like a ladder with the nucleotides representing the rungs on the ladder and the sugar and phosphate are the sides. The double helixes are then wrapped around proteins called histones and packaged into chromosomes.

The other type of genetic material called ribonucleic acid (RNA) is structurally similar to DNA, but there are a few differences--primarily in their chemical bases. Before we get more into the differences, let's examine the similarities. Both have a sugar, phosphate group, and four chemical bases. Unlike DNA which is double stranded, RNA is single stranded. The other major difference is the bases that are found in RNA. RNA contains adenine (A), guanine (G), cytosine (C), and uracil (U). So, in RNA the base thymine is replaced with uracil. In RNA the base pairs are A loves U and C loves G.

A person has a bone fracture and takes a painkiller that causes blood-vessel constriction. Why might this painkiller actually sl

Elan Coil [88]

In contrast to compact bone, spongy bones does not contain true Haversian systems( tiny tubes that form a network in bone and contain blood vessels) but consist of an irregular lattice of thin plates of bone called trabeculae.The spaces between trabeculae are filled with marrow. The cells of the red marrow are responsible for producing blood. Within trabeculae lie lacunae which contain osteocytes.<span> Blood vessels from the periosteum penetrate through to the spongy bone, and osteocytes in the trabeculae are nourished directly from the blood circulating through the marrow cavities.</span>
