In garden peas, one pair of alleles controls the height of the plant, and a second pair of alleles controls flower color. The al
Lerok [7]

Answer:

The parent's genotypes are:

Ddpp - tall, white parent

ddPp - dwarf, purple parent.

Explanation:

This question involves two different genes coding for height and flower color in pea plants. The alleles for tallness (D) and purple color (P) are dominant over the alleles for dwarfness (d) and white color (p) respectively.

According to this question, a tall plant with white flowers is crossed with a dwarf plant with purple flowers to produce the following proportion of offsprings: 1/4 tall purple, 1/4 tall white, 1/4 dwarf purple, and 1/4 dwarf white.

Since some of the offsprings contain recessive alleles for both or either genes, the dominant traits of the parent is controlled by an heterozygous genotype. This means that the tall plant with white flowers has a genotype: Ddpp while the dwarf plant with purple flowers has the genotype: ddPp. In a cross between Ddpp × ddPp, 1/4 of each combination of alleles is produced in the offsprings (see punnet square in the attachment).

Which of the following is an example of using relaxation techniques? a. flight-or-flight response b. visualization c. rational r
kirill115 [55]

Answer:

Option B

Explanation:

Flight-or-flight response is a response or physiological reaction towards external stimuli. Systematic desensitization is a methodology to control anxiety during speech. Hence, these two are not relaxation techniques.  Transforming novelty into familiarity is also a methodology to remain prepared during a speech by practicing it well. Visualization is a technique that helps our mind to relax by using imagination to reach a relaxed state of mind.

Hence, option B is correct

20 POINTS WHO ANSWERS CORRECTLY!!!!! biology
Alex787 [66]

Answer:

They will have a large amount of genetic variation.

Explanation:

Scrapping pollens obtained from one plant to the flower of another plant (different variety but same species) would lead to increase in the genetic pool. The new hybrid plant would carry genetic features from both plants varieties. This process is also used to develop new varieties and have been recognized as cross-pollination. This process is generally preferred over genetic modification (GM) because of more nature friendly.

shtirl [24]

Ecology is made up of the science of biology. Ecology is a science that deals with the relationships between groups of living things and their environments. To exist with one another, organisms belonging to a same species either compete for the resources or divide it amongst themselves, where animals and plants of the same species co-exist and creates a beauty with nature.

rusak2 [61]

Answer:

E. glucosuria (glucose in the urine)

Explanation:

Generally, glycosuria occurs in patients with kidney changes due to diseases such as Wilson's disease or cystinosis, can also be a hereditary problem, but is not expected in patients with kidney damage caused by prolonged lithium use.

Normally, the kidneys filter the blood, eliminating all substances that are not necessary for the body to function, while glucose is reabsorbed in the blood because of its importance in energy production, but people with renal glycosuria do not reabsorb glucose. , which causes it to be eliminated in the urine, occurring glucosuria.
