What are the functions of the roots, stems, branches, leaves, flowers, and fruits in a plant?
Pachacha [2.7K]
Roots absorb nutrients and water from the soil, as well as keep the plant attached to the ground. Some plants also use the roots, to parasite other plants (ie, Mistletoe) or reproduction (Potatoes). 

Stems, transport water and nutried to the plants up reaches, sometimes they are important for protection, as they are covered in thorns or toxins.  

Branches sort of form the same function as stems, only they branch out from the stem.

Leaves, are where the plant conducts its metabolic photosynthetic processes. Sometimes the leaves are also important for protection (the thorns of cacti are actually leaves).

Flower, are useful for reporduction, giving out pollen and when combined with other pollen are turned into fruits.

Fruits are the protective object of the seed, and provide nutrition for the seed, a means of seed dispersion, and lastly protection from outside forces.

AleksAgata [21]

Answer:

<em>The correct option is C) Dd and Dd</em>

Explanation:

To explain the answer, lets make a punnet square with a cross between Dd and Dd.

       D       d

D     DD    Dd

d      Dd     dd

As deafness is a recessive trait, this means that both the alleles in a person should be same and recessive for that trait to occur in the phenotype. A cross between heterozygous carriers show that there will be a 25% probability that the offsprings produced will get the recessive alleles and hence they will be deaf. 50% of the offsprings will have the chance to be carriers like their parents. And there willbe a 25% chance that they will have normal homozygous alleles.

Answer:

The stratosphere

contains the ozone layer ,

is used by airplanes,

has strong, steady winds , and

increases in temperature as altitude increases .

Explanation:

The stratosphere is the atmospheric layer between 10 km and 50 km above the Earth's surface.

It includes the ozone layer, which is at an altitude of about 20 km.

It has strong, steady winds that can reach as high as 220 km/h.

Passenger aircraft generally fly in the lower levels of the stratosphere, at altitudes of about 10 km to 12 km.

Temperatures increase with altitude, from -50 °C at 10 km to -3 °C at 50 km.

A is wrong. The mesosphere (altitude 50 km to 85 km) is the coldest of the atmospheric layers, with temperatures as low as -90 °C at 85 km.
