How does young stem gives mechanical support to the plant body?

The young stem gets mechanical support from the cells found in it. The sclerenchyma and collenchyma are responsible for the support to the plant body. The walls of sclerenchyma are thick as compared to collenchyma and they build up in a uniform layer around the entire margin of cells. They are usually found associated with the term mechanical support. They are found in stem and leaf veins. Collenchyma are mostly found in the areas that are young and grow rapidly.

One is through turgidity. This occurs before ground tissue ( collenchyma and sclerenchyma cells) become well developed to give structural support to the plant as it grows bigger. The xylem tissue (composed of rigid tissue) of the young plant helps render this support and also maintaining osmotic turgidity of the surrounding plant cells.

Please help asap the scientific name Canus nipponicus. To which classification levels does this scientific name belong?

Amiraneli [1.4K]

The correct answer is - C. genus and species.

The final scientific name of an animal represents two things, its genus, and its species.

The first name is the genus of the animal, in this case we have Canus. The second name is the species of the animal, in this case nipponicus.

All living organisms are classified in a same manner: kingdom, phylum, class, order, family, genus, species.

Since the name Canus reminds me a lot of Canis, I will take the wolf as an example:

Kingdom: Animalia

Phylum: Chordata

Class: Mammalia

Order: Carnivora

Family: Canidae

Genus: Canis

Species: C. Lupus

In mammoths, assume that spotted skin (S) is dominant over non-spotted skin (s) and that wooly hair (W) is dominant over non-woo

lisabon 2012 [21]

Answer:

Genotypic and Phenotypic ratios → 1:1:1:1

25% of the progeny is expected to be SsWw, exhibiting spotted skin and wooly hair, SsWw
25% of the progeny is expected to be Ssww, exhibiting spotted skin and non-wooly hair, Ssww
25% of the progeny is expected to be ssWw, exhibiting non- spotted skin and wooly hair, ssWw
25% of the progeny is expected to be ssww, exhibiting non-spotted skin and non-wooly hair, ssww

Explanation:

<u>Available data</u>:

spotted skin (S) is dominant over non-spotted skin (s)
wooly hair (W) is dominant over non-wooly hair (w)
Cross: heterozygous spotted, non-wooly mammoth with a heterozygous wooly-haired, non-spotted mammoth.

Parentals) Ssww x ssWw

Gametes) Sw, Sw, sw, sw

sW, sW, sw, sw

Punnett square) Sw Sw sw sw

sW SsWw SsWw ssWw ssWw

sw Ssww Ssww ssww ssww

F1) 4/16 = 1/4 = 25% of the progeny is expected to be SsWw, exhibiting spotted skin and wooly hair

4/16 = 1/4 = 25% of the progeny is expected to be Ssww, exhibiting spotted skin and non-wooly hair

4/16 = 1/4 = 25% of the progeny is expected to be ssWw, exhibiting non- spotted skin and wooly hair

4/16 = 1/4 = 25% of the progeny is expected to be ssww, exhibiting non-spotted skin and non-wooly hair.

Genotypic and Phenotypic ratios → 1:1:1:1
