Answer:

The given statement is false.

Tropical rainforests are located near the equator and receive precipitation generally in the form of rain. These forests receive a large amount of precipitation throughout the year which can range from 80 inches to 400 inches in a year.

Temperate rainforests are located on higher altitudes as compared to the tropical rainforests. They receive precipitation in the form of rain and snow. They receive less amount of rain as compared to tropical rainforests. They receive precipitation which lies between 40 inches and 60 inches in a year.

Thus the amount and type of precipitation in tropical and temperate rainforests are different.

Which organs perform both mechanical digestion and chemical digestion of food?

kotykmax [81]

Answer: Mouth.

Explanation:

The mouth is known to be performing both the tasks of chemical digestion and mechanical digestion.

The food is ingested through mouth and the teeth perform the process of mechanical digestion by breaking down the food particles into smaller particles.

Then the saliva gets mixed into the food and the enzymes(amylase) present in the saliva helps in the digestion of carbohydrates.

So, mouth is the organ that performs the process of both mechanical and chemical digestion.

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 pictures show close-up views of a fir tree and a cactus.

Akimi4 [234]

The fir tree can be found in the coniferous forest biome, and the cactus can be found in the desert biome.

Option C.

<h3>Explanation:</h3>

Both the cactus and fir trees are having modified tree leaves due to the same purpose - saving water.

The fir trees are found in the coniferous forests which are mainly seen in mountains or in the temperate region. Both the regions face very cold climates and frequent snowfalls in every years. This is why there's a lack of water in the surroundings. This is why they need to save water and minimize transpiration.

Whereas the cacti are found in desert or semi arid regions where water is itself very scarce and temperature is either very high or very low. So they have their leaves converted into spines which help to reduce transpiration.
