Answer:
New allele combinations are acted upon by natural selection.
Explanation:
Recombination may be defined as the process of the exchange of the genetic material between the homologous chromosomes of the non sister chromatid. The combined trait will be visible in the upcoming generation.
The recombination allows the generation of the new genes in the population. These new genes if beneficial for the population will be pass to the next generations. The new allele will be favored by the natural selection and increases the chance of survival of the population.
Thus, the correct answer is new allele combinations are acted upon by natural selection.
Answer + Explanation :
Bacteria :
1) Approximately diameter is 1-5 micrometer
2) They are prokaryotic.
3) They have rigid cell wall containing peptidoglycan.
4) Replicate by binary fission
Fungi :
1) Approximately 3-10 micrometers in diameter.
2) They are eukaryotic.
3) Rigid cell wall containing chitin.
4) Replicate by budding or mitosis.
<u>Viruses :</u>
1) Approximately 0.02-0.2 in diameter.
2) They are eukaryotic.
3) They contain protien capsid and lipoprotien envelope.
4) Donot replicate by binary fission.
<u>Archae :</u>
1) Not typically associated with human disease.
2) Found in extreme environments.
3) Cell wall doesn't contain peptidoglycan.
A daughter cell that matures to the inside of the vascular cambium becomes<u> secondary xylem</u> and a daughter cell that matures to the outside of the vascular cambium becomes <u>secondary phloem.</u>
<u />
- The cambium divides its cells to create secondary xylem and phloem. As secondary phloem and xylem tissue builds up, the stem becomes thicker and develops wood and bark.
- The kind of xylem produced by secondary growth is known as secondary xylem. In contrast, during primary growth, the primary xylem develops.
- As a result, lateral growth, as opposed to vertical growth, is connected with the secondary xylem, as opposed to the primary xylem.
- The procambium, which is found between the xylem axis and the phloem pole, develops into the cambium in the root.
- A pattern resembling the arrangement of secondary stem is produced when xylem forms in the core and phloem on the perimeter of secondary development.
