AVprozaik [17]3 years ago
4 0

Answer: The movement of water throughout a plant is driven by the loss of water through it's leaves, or transpiration. The water molecules that move through the xylem are connected in a continuous “stream”. ... To get the food made in the leaves to other parts of the growing plant requires energy.

Round seeds are dominant over wrinkled seeds in
antoniya [11.8K]

Genotype - RR - 25%, Rr - 50%, rr - 25% (1:2:1)

Phenotype - Round seeds - 75%, Wrinkled seeds - 25% (3:1)

<h3>How explain your answer?</h3>

Let the letter "r" stand for the alleles, where R is round seeds and r is wrinkled seeds. A genotype is an individual's genes represented through alleles. Phenotypes are how the genes express themselves. In other words, genotypes will be written using letters, the alleles, and phenotypes will be the possible outcomes of the alleles.

Both of the parent seeds have the genotypes Rr and the phenotype of round seeds.

If you create punnet square (which had four boxes in total) 1 will have RR, 2 will have Rr, and 1 will have rr. These are the ratios for the genotypes. Each box represents 25%, so the percentages will be 25, 50, and 25. Finally, 3 of these boxes (RR and Rr) will result in round seeds because those are dominant. Only the genotype rr will result in wrinkled phenotype. Therefore, the ratio is 3:1 or 75% to 25%.

Thus, this could be the answer.

Of the following experimental results, which is the best evidence that photosynthesis is more efficient at certain wavelengths o
GarryVolchara [31]

Answer:

The correct answer will be option-C

Explanation:

The plant absorbs the sunlight to perform photosynthesis which helps produce the sugar molecule used by the plants.

The plants absorb maximum sunlight at two wavelengths that are red and blue wavelength by chlorophyll and other pigments. The efficiency of photosynthesis is also measured maximum at these two active wavelengths called action spectrum.

In the given question, since the efficiency of photosynthesis has been discussed which could be measured with the production of oxygen and consumption of carbon dioxide. The experiment performed by the Engelmann showed that aerobic bacteria got concentrated in the blue and red wavelengths as the output of the photosynthesis were observed maximum.

Thus, the selected option is the correct answer.

Misha Larkins [42]

Options for the question have not been given. They are as follows:

A. a lack of urban health care capacity

B. cultural disregard for women and women's health

C. prudence's family medical history

D. a lack of previous medical problems

Answer:

C. prudence's family medical history

Explanation:

Sociological factors include the factors related to human society. These factors stem from the way a society functions and effects the people which are a part of it. The way the society is structured and developed, impacts the people.

Prudence died during childbirth. There can be many sociological causes of her death like low status of women or poor medical facilities in her society. However, her family medical history will not be considered a sociological factor. Family medical history also depends on other factors like genetic composition of the family which is not a sociological factor.
