Answer:
The correct answers would be maintain chromosome number through generations and cause genetic variations by recombination.
In Meiosis a cell divides into four daughter cells all of which have half the number of chromosomes present in a parent cell.
It helps in the formation of gametes in sexually reproducing organisms.
These gametes (one from father and one from mother) fuse together to form a zygote. It re-established the chromosomal number as that of the parent.
In absence of meiosis, the chromosomal number would have doubled after each generation.
In addition, the meiosis also increases the genetic variation among the population with the help of crossing over which occurs during the pachytene stage of prophase I.
During this event, genetic information is exchanged between the non-sister chromatids of the homologous chromosomes. It produces a new combinations of genes that are different from either parent.
Answer:
A handler must know an animal’s pattern of movement in order to avoid injury.
Explanation:
Point of balance refers to equalibrium so if you know the animals pattern of movemenrt you are less likely to get injured while moving on or with it.
Answer:
Translation.
Explanation:
The mRNA formed in the transcription process is transported out of the nucleus, then goes into the cytoplasm, and then to the ribosome. The ribosome is called the cell's protein synthesis factory.
In the ribosome, it directs protein synthesis. Messenger RNA is not directly involved in protein synthesis. Transfer RNA (tRNA) is required for this. The process by which mRNA leads to protein synthesis with the assistance of tRNA is called translation.
So we can say that the transfer RNA (tRNA) is used in the translation process.
Answer:
Green plants are called producers because they manufacture their own food with the aid of photosynthesis.
