linked genes?
Answers
The genes are close jointly chromosomes, they are linked. Mendel’s conclusions hold that had different effects if both traits would have been linked traits.
What was the determination from Mendel's experiments?
When genes are consolidated together on the identical chromosome, they are expressed to be linked. That indicates the alleles, or gene versions, already jointly on one chromosome will be inherited as a unit additional frequently than not.
Mendel’s work proceeded virtually unnoticed by the scientific community, which mistakenly believed that the process of inheritance involved a blending of parental traits that assembled an intermediate physical impression in offspring.

components of the molecule.
During DNA replication, which chemical bonds break apart? Select all that apply.
Answers
The DNA has two double strands, and they have different chemical bonds, so during the DNA replication, the hydrogen bonds that are present between the two strands break to separate the DNA.
What role does DNA replication play?DNA replication is the process of making two DNAs from a single DNA, and here the hydrogen bonds that are present between the bases, such as thymine and adenine, which have two hydrogen bonds, and guanine and cytosine, which have three hydrogen bonds, break. The purpose of DNA replication is to make a copy of the genetic content of the cell so that it can be passed to other cells.
Hence, the DNA has two double strands, and they have different chemical bonds, so during the DNA replication, the hydrogen bonds that are present between the two strands break to separate the DNA.

Answers
Answer:
The trees and plant withstand rotting in tropical rain forest using some of these mechanisms.
Explanation:
Tropical rain forests are known for the presence of heavy rainfall, due to this, there might be a lot of water retention in the root. Some trees and plants however are able to store this water and use some of the below mentioned methods to prevent decay and rot.
Some trees in the tropical rain forest may produce very hard outer layer, these hard outer layer will protect the plant and trees form predators and microorganisms from penetrating into the inner tissues of the tree.
Some withstand rotting by producing chemical compounds, these chemical compounds prevents predators and microorganisms from destroying the plants and trees.
