Benefits of rainforest ecosystems. 1. Preservation of species. Because they are so biodiverse, healthy rainforest ecosystems are the perfect places to preserve huge numbers of species that would otherwise be endangered.
Rain forest ecosystem have several advantages like preserve species, biodiversity is high etc.
what are the types rainforest ecosystem ?
The major constituents of a rainforest ecosystem are tall evergreen trees, it is formed due to heavy annual rainfall, high temperature, poor quality soil and rich in biodiversity.
There are different types of rain forest such as Tropical rainforests which is present near to the equator, the climate is hot and humid.
Temperate rainforests present in extreme temperate zones, close to coastal areas and the climate is cooler than tropical rainforests.
Third is Flooded forest where dry forest can be flooded by heavy rains or due to tidal river surrounding the forest, climate is highly humid.
Lowland rainforests refers to either tropical or temperate present near to valley. Cloud forests or Montane rainforests is located on the top of mountain top, partially in cloud.
Finally, mangrove forests are also called as mangrove swamps, trees are waterlogged ground.

Assume that the genes from the previous example are located along the chromosome in the order X, Y, and Z. What is the probability of recombination between genes X and Z
Knowing the order or the genes in the chromosome and the recombination frequencies in region 1 and 2, we can assume that there are 30% the probability of recombination between genes X and Z.
Recombination frequencyWhen talking about recombination frequencies, we are refering to the probabilities of recombination or crossing over between two genes.
When these genes are too close in the same chromosome, we say they are linked, and the recombination frequency might be too small.
Crossing-over between linked genes that are very close to each other in the chromosome is not that common.
A short distance between genes is a very little target for crossing-over to occur, which means that only a few of them will happen, compared with the number of events between genes that are more separated between each other.
Available data
The recombination frequency between X and Y = 25%The recombination frequency betqeen Y and Z = 5%The order of the genes in the chromosome is X, Y, ZHere we have the recombination frequency in region 1 (X-Y) and the recombination frequency in region 2 (Y-Z).
To get the value of the recombination frequency between the two extremes, we just need to add the two regions values.
R1 + R2 = Rt
25% + 5% = 30%
X----------R1----------------Y-----R2----- Z
X----------25%-------------Y------5%----Z
X-----------------------30%-----------------Z

what is the process of photosynthesis
The process of photosynthesis is the synthesis of food molecules from inorganic compounds using energy from sunlight.
WHAT IS PHOTOSYNTHESIS?Photosynthesis is the process whereby green plants obtain their food (glucose) in the presence of sunlight as an energy source.
Photosynthesis takes place in two stages namely;
Light dependent reactionsLight independent reactionsPhotosynthesis combines carbon dioxide and water as reactants as follows:
6CO2 + 6H2O = C6H12O6 + 6O2
Therefore, the process of photosynthesis is the synthesis of food molecules from inorganic compounds using energy from sunlight.

What is DNA?It should be noted that deoxyribonucleic acid, is the hereditary material that is found in humans and all other organisms.
DNA replication is a complex process that involves many enzymes and the complex formed by the enzymes to make an exact copy of the DNA during cell division. DNA replication enzymes are common in both prokaryotes and eukaryotes but the site of DNA replication differs.
The difference between prokaryotic and eukaryotic DNA replication is that the prokaryotic DNA replication takes place through a single origin of replication. In contrast, eukaryotic DNA replication occurs through multiple replication origins.
The nucleus is an organelle that carries the genetic material of the cell. Therefore, DNA replication does not take place in the nucleus but in the cytoplasm.
In conclusion, the label that would change if this DNA process took place in a prokaryotic cell is the nucleus.

There are 20 standard amino acids. Ninhydrin turns yellow when it interacts with proline. Ninhydrin turns purple in the presence of the other 19 amino acids. Can you determine the identity of each of these 19 amino acids using ninhydrin test only? why or why not
Because the ninhydrin test produces the same purple color for all amino acids except for proline, it cannot be used to identify all other 19 amino acids.
What are amino acids?Amino acids are the molecules from which proteins are made.
Amino acids contain an alpha amino and carboxyl group, with a side chain group attached.
The ninhydrin test is used to test for the presence of amino acids generally and for proline specifically.
Since the ninhydrin test produces the same purple color for all amino acids except for proline, it cannot be used to identify all other 19 amino acids.
