Answer:Option C

Explanation:

Wilting can be defined as the process in which the leaves in the plants drops down.In normal conditions the water is absorbed by the roots and then it is stored in the vacuoles of the cell.

When there is lack of water in the plant body then the xylem releases all of its water and the leaves of the plant drops down.

This is done in order to decrease the surface area of exposure so that there is less requirement of water.

The xylem releases all its water when we observe plants that wilt.

Answer: Option C

Explanation:

Wilting is a process where the plant loses its rigidity and droops down. To understand it better the water is absorbed through the roots and aids in the functioning of the plant. The excessive water is stored inside the vacuole when during water scarcity releases water.

But during the drought conditions the water is lost completely causing the leaves to shrink. The xylem starts releasing all its water leaving a less surface area. Hence the leaf shrinks and wilting occurs.

Why doesn''t the patellar reflex happen when your leg is straight?

irga5000 [103]

The patellar reflex can be defined as the kicking movement of the lower leg which occurs with a sudden twitch when the patellar tendon of a person is tapped. This patellar tendon is present below a person's kneecap. This reflex happens only when the leg is bended. It is impossible for patellar reflex to occur if the leg is straight as the quadriceps muscles are already contracted and a sudden kicking movement of the leg in such state could not be elicited. The patellar reflex protects the quadriceps from stretching too much.

Complete the sentences by matching the names of trees to the appropriate blanks.

raketka [301]

Answer: A: Pine, Cedar and Mango.

B: Pine and Cedar

C: Mango, Cedar and Elm

D: Pine and Cedar

Explanation: Evergreens plants always have there leaves on regardless of the season, because their roots go very deep into the soil getting water and nutrients far below the levels other tap roots can go, they are mainly found in the rain forest region that have abundance of water. Example, Mango

Deciduous trees are usually found at desert places that dont always have water, so they lose their leaves during etreme weather to reduce the rate of evaporation of water on its surface. Example, Maple.

Hardwood: These are flowering plants. they usually have broad leaves and nuts. example, Mahogany.

Conifers: These are cone bearing seed plants. they are perennial and woody plants. Example Pine.

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.

The circulatory system consists of three independent systems that work together: the heart (cardiovascular), lungs (pulmonary), and arteries, veins, coronary and portal vessels (systemic). The system is responsible for the flow of blood, nutrients, oxygen and other gases, and as well as hormones to and from cells.
