Bonds between atoms break and new bonds form correctly describes a chemical reaction
<u>Explanation:</u>
The process of resetting the integral fragments of the reactants to produce diverse items as outcomes is termed as a chemical reaction. Effects transpire when pair or further particles fuse and the particles transfer. Bonds between atoms are split and designed to develop new fragments.
Chemical reactions need to be separated from physical alterations. The physical aspects of a thing will vary during physical conversion befalls, still the chemical identification will endure the equivalent. Chemical bonds are formed or split to formulate a unique molecule. Individual reactions often occur as part of a broader list of reactions.
Question
What must happen before meiosis can begin
DNA replication must come first before meiosis to happen.Previous to replication, a germ cell contains two copies of each chromosome, a maternal copy. and a paternal copy.
Answer:
Option C, They allow random distribution of genetic material when a cell divides.
Explanation:
The chromatin are responsible for packaging of DNA molecule into smaller space with in a chromosome. It not only package it but also protect it from. Packaging allows for easier division of cells during mitosis and meiosis and hence prevent any kind of damage to the DNA.
Chromosomes make recombination and random segregation of genetic material to form new cells. Each new cell gets equal number of chromosomes
Hence, option C is correction
Answer:
plants are the main producer in a forest
Explanation:
because if the herbivores don't get their food then they die, and if they die carnivores die and there is no more forest
Answer:
Daughter chromosomes move toward opposite poles of the cell.
Explanation:
Prophase is the beginning of cell division. At this stage, the CHROMATIN from which the chromosomes are formed thickens and twists spirally and CHROMOSOMES are formed which become visible under a microscope.
CENTRIOLS are organelles whose main role is to form a dividing spindle during cell division, now they separate and move towards the poles of the cell.
When they reach the poles, the threads of the dividing spindle are formed between them. Chromosomes are attached to these threads.
