Answer:
two types
During meiosis without crossing over, the alleles of two genes located on each chromosome migrate together and stay attached. We obtain, therefore, gametes that are 100% "parental", subdivided into two types of gametes from the point of view of allele separation.
Answer:
The arrow labelled X is ribosome.
Explanation:
Ribosomes can be described as structures which are the protein manufacturing unit.
For a protein to form, The DNA forms mRNA by the process of transcription. The start and stops codons are attached to the mRNA and it travels outside the nucleus into the cytoplasm where ribosomes are present.
The ribosomes are the site where the process of translation takes places. The process of converting RNA into proteins is termed as translation.

Answer:
y=10
Explanation:
Given the expression 7 - y = -3
First we have to collect all constant term to one side hence
7+3-y=0
10-y=0
10=y
y=10
The root nodules of leguminous plants houses nitrogen-fixing bacteria called Rhizobia. Rhizobia has a symbiotic relationship with leguminous plants that allows both to benefit from each other.
By binding to hydrogen, the Rhizobia bacterium is able to convert or fix nitrogen gas into ammonia , a form that the plant can use. Likewise, the legume plant provides the rhizobia bacterium with carbohydrate which the rhizobia depends on for energy. It is important to note that the carbohydrate sent to the nodules for the rhizobia is also what is used as a source of hydrogen to help the bacterium convert nitrogen to ammonia.
