A chemical reaction is a process in which one or more substances are changed into new substances.
An example of a chemical reaction is when metal rusts.
Answer:
They do not contain chromosomes. (Ans.C).
Explanation:
Cyanobacteria also known as blue-green algae, they are heterogeneous group of photosynthetic prokaryotic organisms. Like prokaryotes such as bacteria, cyanobacteria lack endoplasmic reticulum, mitochondria, membrane bound nucleus, and Golgi apparatus. Bacteria are simpler than other organisms, and single celled microbes.
Both bacteria and cyanobacteria reproduce through the asexual method either by binary fission in unicellular, multiple fission in colonial form or by spore formation, and fragmentation in filamentous species.
The answer is A, we know this because mitosis, is a part of meiosis. So this excludes C, and D. and Cloning usually occurs in prokaryotic cells.
Answer:
D
explain: The Move from high concentration to low competition. Until the concentration is equal . Diffusion expand needs no energy
<span>If the parents are both heterozygous for </span><span>particular traits their genotype would be: AaBb x AaBb ( this cross would be the F1 generation while the P generation is the one that originated the parents).
This cross would result in the folowing genotypes:
AABB
AaBB
Aabb
aaBB
aaBb
aabb
Dominant for A and B: 9/16
Dominant for A but recessive for B: 3/16
Recessive for A but dominant for B: 3/16
Recessive for A and B: 1/16
ratio: 9:3:3:1
To answer you the possible phenotypes is difficult because your question is missing information about what each gene does, but I know it would be 4 different phenotypes.
