How are the reactants and products of photosynthesis and respiration related to one another?

1 answer:

6 0

Photosynthesis and respiration can be stated as complementary process to each other as the product of one process is used in the other process.

Plant capture energy from the sun and the following chemical reaction takes place –

CO2 + H2O + light energy = Sugars + O2

Product sugar (glucose) and oxygen is released into the atmosphere.

Now in respiration, the carbohydrate and oxygen is used to produce carbon dioxide, water and energy by organisms other than the producers (plants) . The chemical reaction involved is shown below:

Carbohydrate (Sugar) + O2 = CO2 + H2O + energy

The carbon dioxide, water and energy released in respiration is then used by the green plants to produce carbohydrates (glucose/sugar) and oxygen.

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 environment is most likely to be characterized by dry scrub with frequent fires?

Katyanochek1 [597]

Environments likely to be characterized by the presence of dry scrubs and frequent wildfires are those that lack the presence of rain and suffer high sunlight hours.

When referring to the terrestrial biomes that meet the characteristics described, we can include:

Temperate grasslands
Cold deserts

The temperate grassland/cold desert biomes have:

cold and dry winters
hot, dry summers
Extended sunlight hours

This biome is very dry, and the harsh weather makes it difficult for plants to grow, leading to their dry scrub characteristic. This biome also experiences frequent wildfires due to the intense sunlight and lack of rain to which it is exposed.
