Answer:

A Plant stem carries out vital resources to the rest of the plant.

Explanation:

Carrying out vital functions such as the transportation of water, food, and nutrients to the rest of the plant. These transportations are done by the xylem ( carries water ), and the phloem ( carries nutrients ). The plant also supports the plant and firmly fixes it in one area in the soil. Depending on the plant's structure, the plant stem may be rigid, sturdy, or flexible.

Hope this Helps!

A population of wild-flowers was scored for flower color. There were 302 blue (BB) plants, 1857 violet (BR) plants and 811 red (

Paul [167]

Answer:

frequency of the blue (B) allele $= 0.4142$

frequency of the red (R) allele $= 0.5858$

The number of blue plants expected is $509.652$

The number of red plants expected is $1019.304$

The anticipated number of violet plants is $1441.341$

Calculated chi square value

$= 84.5320 + 42.5688 + 119.8692\\= 246.97$

Explanation:

Frequency of blue allele is

Frequency of blue allele is equal to sum of frequency of BB and half of frequency of BR

$\frac{302}{2970} + \frac{1}{2} \frac{1857}{2970} \\= 0.1016 + 0.3126\\= 0.4142$

Frequency of other allele

$1- 0.4142\\= 0.5858$

Chi Square test

Interpret the chemical reaction - what is the overall purpose of photosynthesis?

juin [17]

<h2>interpret the chemical reaction - what is the overall purpose of photosynthesis?</h2>

The main purpose of photosynthesis is to convert radiant energy from the sun into chemical energy that can be used for food. Cellular respiration is the process that occurs in the mitochondria of organisms (animals and plants) to break down sugar in the presence of oxygen to release energy in the form of ATP.

Which of the following is true of receptors for dynamic equilibrium?

gulaghasi [49]

Answer:

The correct answer is option D.

Explanation:

Dynamic equilibrium refers to the sense, which interprets angular acceleration in the three-axis of rotation that when combined provides a sense of equilibrium when movement takes place. The receptors for dynamic equilibrium are known as ampulla, maculae are the receptors of static equilibrium.

The movement of the head does stimulate dynamic equilibrium receptors, as these receptors are situated in the inner ear that moves with the head. The receptors for dynamic equilibrium are situated in the semicircular canals. The receptors for dynamic equilibrium react to rotational forces, as the receptors are located on the three-axis, thus, they can detect rotation, that is, angular momentum.
