Interesting facts about rainforest biome

1 answer:

6 0

1. Rainforests only cover around 2 percent the total surface area of the Earth, but really about 50 percent of the plants and animals on the earth live in the rainforest.

2. There are two different types of rainforests, and they include both temperate and tropical. The tropical rainforests are the ones that are most commonly found around the world.

3. A fifth of our fresh water is found in tropical rainforests, the Amazon Basin to be exact.

4. Within four square miles of tropical rainforest, you will find 1500 flowering plant species, 750 types of trees, and many of these plants can be helpful in combating cancer.

5. Rainforests are threatened each and every day, especially by practices such as agriculture, ranching, logging and mining.

Hope this helps!

Why are cinder cones short-lived?

Reptile [31]

Usually the lava flows come towards the end of the eruption, once the magma has lost enough of its volatiles to flow more quietly. Cinder cone eruptions are comparatively short lived, and thus cinder cones are much smaller features than stratovolcanoes and shield volcanoes (usually no more than a mile at the base).

The light-independent reactions of photosynthesis, also known as the Calvin cycle, use and produce a variety of molecules. Sort

Margaret [11]

Molecules brought in and used in the calvin cycle - Carbon dioxide $(CO_2)$ , Ribulose bisphosphate (RuBP)

Molecules produced during the calvin cycle that leave the cycle - a few of the glyceraldehyde-3-phosphate (G3P), NADP+

Molecules used and regenerated within the calvin cycle - most of the Glyceraldehyde-3-phosphate (G3P) , NADPH

Explanation:

Calvin cycle is the light independent reaction that takes place in the stroma of the chloroplast. Calvin cycle uses ATP and NADPH produced during the light reaction. Calvin cycle occurs in 3 steps, they are:

1. Carbon fixation - $(CO_2)$ combines with Ribulose bisphosphate (RuBP) to form 2 molecules of 3-phosphoglyceric acid (3-PGA).

2. Reduction - ATP and NADPH is used to convert 3-PGA into glyceraldehyde-3-phosphate (G3P).

3. Regeneration - some G3P molecule form glucose while other regenerates to form RuBP acceptor.

In a certain plant, tall stems (t) are dominant to short stems (t). a farmer crosses a short-stemmed plant with a heterozygous l

melisa1 [442]

The answers would be:

Genotype Phenotype

Tt Tall stemmed

tt Short stemmed

Genotypic ratio : 2:2 or 1:1

Phenotypic ratio: 2:2 or 1:1

You can read on to see how this was done:

Tall stems (T) are dominant to short stems (t).

First figure out the genotypes of the parents. We have a short-stemmed plant and a heterozygous long-stemmed plant cross.

For short stem to occur, you need 2 pairs of short alleles. So the first parent would have a genotype of tt.

Heterozygous long-stemmed means that the parent has one of each allele. So the genotype of the second parent would be, Tt.

Now we can make our Punnett Square.

tt x Tt

t t

T | Tt | Tt

t | tt | tt

Let's list down the genotypes and phenotypic results.

Genotype no. Phenotype

Tt 2 Tall stemmed

tt 2 Short stemmed

So from that we can answer the other questions:

Genotypic ratio : 2:2 or 1:1

Phenotypic ratio: 2:2 or 1:1
