In this activity, you will distinguish the theories of spontaneous generation and biogenesis.

zhannawk [14.2K]

Answer:

Biogenesis = <u>Life from life</u> : Spontaneous Generation = <u>Life from non-living things</u>

Explanation:

As an accurate statement of the difference between spontaneous generation and biogenesis:

Spontaneous generation that sometimes refers to "abiogenesis" is an idea that life comes from non-living things/components. Whereas biogenesis is a contemporary concept that life can only arise from another living thing.

Cell division, a baby of mice born from adult males and females, etc. are some examples of biogenesis. In contrast, there is no example of spontaneous generation. It remains a theoretical concept.

Why is it imprtant for the ova and sperm cell to each contain a haploid number of chromosomes?

Katyanochek1 [597]

Meiosis makes sperm and eggs. ... The result is 4 haploid daughter cells known as gametes or egg and sperm cells (each with 23 chromosomes – 1 from each pair in the diploid cell). At conception, an egg cell and a sperm cell combine to form a zygote (46 chromosomes or 23 pairs).
