Answer:
Asexual is reproduction with one parent (single celled organisms)
Sexual is reproduction with two parents
Explanation:
<h2>
<u>Asexual reproduction</u> </h2>
is a type of reproduction by which offspring arise from a single organism, and inherit the genes of that parent only; it does not involve the fusion of gametes and almost never changes the number of chromosomes. Asexual reproduction is the primary form of reproduction for single-celled organisms such as the archaebacteria, eubacteria, and protists.
<h2>
<u>Sexual Reproduction</u></h2>
Sexual reproduction is a form of reproduction where two morphologically distinct types of specialized reproductive cells called gametes fuse together, involving a female's large ovum (or egg) and a male's smaller sperm. Each gamete contains half the number of chromosomes of normal cells.
Answer:
It is a polar molecule
Explanation:
There is no such thing as tri-polar. Water cannot be non-polar due to its partial charges. Water is not a chimeric molecule because it has a plane of symmetry.
Answer:
Balanced
Explanation:
It should be understood that the method used above by the farmers is known as artificial crossing, or artificial insemination when describing the act in animals.
This method is usually adopted to achieve an excellent results from two organisms of different traits.
In this case, the plant or crop with small fruits might have some needed traits like ability to withstand drought, which the other plants with big fruits does not have.
Therefore, the crossing will help to produced a plant which its fruit will be balanced with both traits.
Answer:
Option A is correct (Alfred Wallace).
Explanation:
Option A is correct (Alfred Wallace).
According to the evolution theory all living species are evolved from a simple life source with the passage of time.
Points of natural selection:
- Genetic variation are passed from generation to generation but environment can cause variations too.
- Individuals in species have gene variation which is due to random mutation
- Those who can not adopt to environment can not have their genes pass to next generation.
- Natural Selection is also called as "Survival of the fittest".
I am not totally sure but I think it might biosphere
