Answer:
a virus, because it requires a host cell to reproduce
Explanation:
- a bacterium, because it is contagious
-
a fungus, because it infects livestock
-
a protist, because it is microscopic
-
a virus, because it requires a host cell to reproduce
The correct answer would be <u>a virus because a virus is the only microbe that cannot reproduce on its own without a host</u>. A virus utilizes the genetic mechanism of its host to reproduce either lytically or lysogenically.
<u>In lytic cycle</u>, the virus utilizes the genome system of the host to produce more viruses that eventually leave or lyses the host to become independent viral particles, killing the host in the process.
<u>In lysogenic cycle</u>, the virus inserts its genome into that of the host and uses the host's replication machinery to replicate its genome. The virus then waits for the defense mechanism of the host to become weakened before multiplying and lysing the host.
Answer:
Outside factors are not always constant meaning that there is little way to control them.
Explanation:
Answer:
Assuming the dominant allele is represented as A, and the genotype as AA and the recessive as a, and genotype as aa; then the F1 will produce the offispring. Aa, Aa, Aa,Aa in ratio: 1:1:1:1:1
This shows the dominance of allele A.
However if two of the F1 generation are crossed then:
The F2 is AA,Aa,Aa,aa the phenotypic ratio is
3 ; 1
W<u>hile the Genotypic ratio is ratio;</u>
<u> 1AA : 2Aa Aa; 1aa(1 ;2;1)</u>
Explanation:
Answer:
When all of the populations live together in the same area, it is called:
A community
Why? Because a community occurs when multiple people are together, and the prefix com means "together".
