Answer:
D. Diseases are caused by the presence and action of specific microorganisms.
Explanation:
Answer:
A. DNA replication
B. Two haploid daughter cells
C. Four haploid daughter cells
D. No, they are not the same
E. Gametes
Explanation:
A) Step 1 and Step 2, according to the image attached to this question, depicts the stages of interphase where the REPLICATION of genetic material occurs i.e formation of sister chromatids.
B) Meiosis occurs in two division steps namely meiosis I and meiosis II. Meiosis I, which involves the separation of homologous chromosomes produces TWO haploid daughter cells.
C). However, in meiosis II, sister chromatids separate to produce FOUR haploid daughter cells.
D) The cells in step 4 are not all the same due to a process called CROSSING OVER, which occurs in the Prophase of meiosis I. Crossing over exchanges chromosomal segments between two non-sister chromatids of homologous chromosomes as seen in the color of the images attached.
E) The four daughter cells produced in step 4 will mature into GAMETES, which will be used in sexual reproduction.
The correct answer is Metal.
Sound waves are vibrations which need medium to propagate. Higher the density of medium, the sound travels fastest. Sound travels fastest in solid than liquid and gas. Therefore, in this question sound will travel faster in metal because metal has higher density than air and water and it will not travel in vacuum as sound needs medium to travel.
The answer for that is B, and E it should be all in your book
