Explanation:
Meiosis produces haploid gametes (ova or sperm) that contain one set of 23 chromosomes. When two gametes (an egg and a sperm) fuse, the resulting zygote is once again diploid, with the mother and father each contributing 23 chromosomes.
<h3><u>Answer;</u></h3>
The above statement is <u>False </u>
<h3><u>Explanation;</u></h3>
- Speciation is an evolutionary process in which new species arise. There are three types of speciation, namely; sympatric, parapatric and allopatric speciation.
- <em><u>Sympatric speciation is a pattern in which speciation occurs in the absence of a physical barrier to gene flow; ex. polyploidy arising in flowers.</u></em>
- In an Allopatric speciation on the other hand, a physical barrier arises and separates two populations, ending gene flow between them and allowing reproductive isolating mechanisms to evolve so that later if the two groups come back into contact they will no longer be able to reproduce together, therefore making them different species.

thats the definition
but i dont know the statements so i cant help much after that.</span>
Answer:
b. They cannot reproduce outside of a host cell.
Explanation:
Viruses are <em>parasitic organisms</em> that need a<em> host</em> in order to<u> thrive</u> and <u>reproduce</u>. This means that they cannot replicate outside of a host cell, but can only do this by parasitizing it. They have to find a host cell in order to continue their life-cycle or else they won't thrive. The word "obligate" means <em>being restricted to a specific mode or function in life</em>. This shows that the virus has a restriction when it comes to <u><em>reproduction.</em></u> It cannot reproduce without finding a host cell.
Answer:
4.2 Newtons
Explanation:
Force=mass x acceleration
Force = 6 kg x 0.7 m/s/s = 4.2 kg m/ s/s = 4.2 Newtons
