What is the main function of vascular tissue in vascular plants?

2 answers:

8 0

The vascular tissue conducts water and minerals from the roots upward and throughout the plant, and phloem, which transports dissolved nutrients in all directions within the plant. The main conducting vessels of xylem are the tracheids and the vessels.

Answer and Explanation:

Vascular tissue is complex tissue which is made up of more than one type of cell.

It is found in vascular plants.

Main components of vascular tissue are as follows:

1) Xylem

2) Phloem

Xylem helps in conducting water whereas phloem helps in conducting food to the plant.

So, vascular tissue is required for conducting water, minerals and all necessary nutrients to the vascular plants.

Answer:

C. Balancing a chemical equation simply means ensuring that the same numbers of atoms of the elements which are involved in the reaction (reactants) are represented in the result of the reaction (products). This demonstrates that matter is not created nor destroyed in a chemical reaction.

Explanation:

The products of a reaction contains a certain number of each atom constituting each product;

Matter cannot be created or destroyed so the reactants must contain the same number of each atom;

Balancing the equations means this will be the case and hence, this will demonstrate the number of each reactant atom/molecule necessary for the reaction to proceed

What is the elevation of point B

Alika [10]

Answer: c. Point B has an elevation less than 2750 feet.

Explanation:

The lines drawn on the map are known as contour lines and they are used to measure elevation. Point B is on a river and rivers are only able to flow at a lower elevation than the area around them.

Point B is therefore lower than the area around it and as the closest contour line to it puts the area at an elevation of 2,750 feet, that must mean that Point B is lower than 2,750 feet.

1. In a population of 200 field mice, 98 mice are homozygous dominant for brown fur (FF), 84 mice are heterozygous (Ff), and 18

iVinArrow [24]

A.
The genotype frequencies can be determined by dividing the number of individuals with a genotype by the total number all the individuals.
FF genotype frequency:
98÷200=0,49. There are approximately 5 homozygous dominant mice in 10.
Ff genotype frequency:
84÷200=0,42. There are approximately 4 heterozygous mice in 10.
ff genotype frequency:
18÷200=0,09. There are approximately 1 homozygous recessive mouse in 10.

B.
To determine the frequency of an allele we can divide the number of times that the allele appears by the total number of alleles.
F allele frequency:
 $\frac{(98*2)+84}{400}$ =0.7
There are 7 F alleles in 10 random alleles.
f allele frequency:
$\frac{84+(18*2)}{400}$ =0.3
There are 3 f alleles in 10 random alleles.
