Which can remove carbon dioxide from the atmosphere

In a unique species of plants, flowers may be yellow, blue, red, or mauve. All colors may be true-breeding. If plants with blue

Zolol [24]

Answer:

F1) 100% bbRr, red flowered plants.

Explanation:

<u>Available data:</u>

flowers may be yellow, blue, red, or mauve
colors may be true-breeding
the cross of blue-flowered plants with red-flowered plants, produce plants that have yellow flowers
F2 generation: 9/16 yellow, 3/16 blue, 3/16 red, and 1/16 mauve.

Knowing that the phenotypic ratio is 9:3:3:1, we can assume that there are two genes involved in the flower color expression. We can name these genes B and R with a dominant and a recessive allele each (B, b and R, r respectively).

According to the first cross, we might establish the following genotypes:

1st Cross: blue-flowered plant x red-flowered plant

Parentals) BBrr x bbRR

Gametes) Br, Br, Br, Br bR, bR, bR, bR

F1) 100% BbRr, yellow plants

Parentals) BbRr x BbRr

Gametes) BR, Br, bR, br

BR, Br, bR, br

Punnett square) BR Br bR br

BR BBRR BBRr BbRR BbRr

Br BBRr BBrr BbRr Bbrr

bR BbRR BbRr bbRR bbRr

br BbRr Bbrr bbRr bbrr

F2) 9/16 yellow ---> 1/16 BBRR + 2/16 BBRr + 4/16 BbRr + 2/16 BbRR

3/16 blue ------> 1/16 BBrr + 2/16 Bbrr

3/16 red---------> 1/16 bbRR + 2/16 bbRr

1/16 mauve ----> 1/16 bbrr

So,

Yellow-flowered plants: BBRR, BBRr, BbRR, BbRr
Red-flowered plants: bbRR, bbRr
Blue-flowered plants: BBrr, Bbrr
Mauve-flowered plants: bbrr

According to these genotypes, the second cross would be like following,

2nd Cross: true-breeding red-flowered plants with true-breeding mauve flowered plants.

Parentals) bbRR x bbrr

Phenotype) Red Mauve

Gametes) bR, bR, bR, bR br, br, br, br

Punnett square) bR bR bR bR

br bbRr bbRr bbRr bbRr

F1) 100% bbRr, red flowered plants.

The local reaction that occurs in the body as a result of invasion or injury is called the _____________ _________________

brilliants [131]

Answer:

Inflammation

Explanation:

The inflammatory response (inflammation) can be described as a localized response to an injury or to the destruction of tissues. It occurs when tissues are injured by bacteria, trauma, toxins, heat, or any other cause. The cells in damaged tissue release chemicals that can cause swelling, redness, heat, pain in the damaged area, all as part of the healing process. Some of those chemicals are cytokines that bring in body's immune cells. Others are histamine and prostaglandins which cause swelling, pain and fever. As the body heals, the inflammation gradually decreases.

Give one explanation of each type of protist that explains why it is animal-like, plant-like, or fungus-like.

Alex777 [14]

<u>Type of protist:</u>

ANIMAL LIKE PROTIST:

PROTOZOA - They are commonly called as protozoa. Most protozoa consists of the single cell. They are animal like because they are heterotrophs and are capable of moving. Protozoa are not animals ,they are ancestors of the animals.

PLANT LIKE PROTIST:

ALGAE-They are large and diverse group . the main reason is that they contain chloroplasts and produce the food through photosynthesis.

FUNGUS LIKE PROTIST:

MOLDS -They are absorptive feeders on decaying organic matter. they resemble fungi and they reproduce with spores as fungi. They are quite different from fungi and more like other protists.
