The main plant tissue that the lines in the enlarged diagrams point to is the ground tissue.

<h3>What are ground tissues in plants?</h3>

Ground tissues in plants refer to the collenchyma tissues, the parenchyma tissues, and the sclerenchyma tissues.

In other words, they are tissues that are neither dermal nor vascular in origin.

Different ground tissues perform different functions depending on the part of the plants in which they are found. the functions range from photosynthesis in leaves to storage in roots, and support functions.

Species A has a diploid number of 42 chromosomes, while species B has a diploid number of 48 chromosomes. Give the chromosome nu
Arada [10]

Answer:

a. autotriploid of species A: 63 chromosomes

b. autotetraploid of species B: 96 chromosomes

c. allotriploid from species A and B: 1) 66 chromosomes and 2) 69 chromosomes

Explanation:

<u>For a.</u>

this species will have 3 haploid sets of chromosomes ('tri' means 3)

one haploid set = 21

21 × 3 = 63 chromosomes

<u>For b.</u>

this species will have 4 haploid sets of chromosomes ('tetra' means 4)

one haploid set = 24

24 × 4 = 96 chromosomes

<u>For c.</u>

there are two ways to do this:

1) two sets of chromosomes from species A and one from species B

42 + 24 = 66 chromosomes

2) one set of chromosomes from species A and two from species B

21 + 48 = 69 chromosomes

Hope that answers the question, have a great day!

Your aunt grows sprouts hydroponically. from where do her plants get nutrients?
larisa [96]
Hydroponics way of growing, is way of farming, in which plants are grown in nutrient rich water. So, in Hydroponic growing of sprouts, sprouts get their nutrients from the nutrients supply like liquid fertilizers which are mixed with the water. It is one of the advantage of hydroponic means of growing because, unlike in soil system, the plants root does not have to work hard to get nutrient from underground. The easy availability of nutrients and other condition like water, pH level etc makes plants grow faster are fuller.

Also, advancement of technology have made it possible to prepare built-in hybrid hydroponic system which have multiple ways of delivering nutrient to specific plants.

In ducks, the trait for normal feathers is dominant to the trait for silky feathers. If
vesna_86 [32]

Answer: The genotype ratio is 2Ff : 2ff

The phenotype ratio is two normal feathered birds to two silky feathered birds.

Explanation: Let F represent the gene for normal feather and f represent the gene for silky feather. F is dominant while f is recessive, therefore a male that is hybrid for trait of normal feather is heterozygous and will have a genotype of Ff, a female that is homozygous for silky feather will have a genotype of ff.

A cross between Ff and ff will yield 2Ff birds and 2ff birds. Since F is dominant, a bird having genotype of Ff will manifest outwardly as blue feathered birds while ff will manifest outwardly as silky feathered birds because f is recessive and must occur in a homozygous condition in order to manifest phenotypically. Therefore, the genotype ratio is 2Ff: 2ff.

What is the Mid-Atlantic Rift ​
scoray [572]
The mid Atlantic rift is in the middle of the Atlantic Ocean where 2 plates diverge. That means that the 2 plates are moving away from each other, and the mantles lava is filling the gap between the two plates. The newest land is located closest to the ridge, and the oldest land is located farther away from the ridge.
