Why do people feel fireworks before hearing it?
mars1129 [50]

Answer:

People feel fireworks before hearing it because light travels faster than sound.

Explanation:

We always see the colors of the fireworks before hearing their defeaning sounds. This is because light travels faster than sound, so we can see the light before hearing the sound. An example of this is seeing lightning before hearing thunder. When lightning strikes, the air around it moves very quickly, causing vibrations.

In ______ reproduction, genetically identical offspring are produced, while in ______ reproduction, offspring are genetically di
xxTIMURxx [149]

In <u>asexual </u>reproduction, genetically identical offspring are produced, while in <u>sexual </u>reproduction, offspring are genetically different from each other.

Sexual reproduction is a sort of reproduction that involves a complex existence cycle wherein a gamete (inclusive of a sperm or egg mobile) with an unmarried set of chromosomes (haploid) combines with another to provide a zygote that develops into an organism composed of cells with two sets of chromosomes (diploid).

Sexual reproduction is the maximum common existence cycle in multicellular eukaryotes, which includes animals, fungi, and plants.

Asexual reproduction is a sort of reproduction that doesn't involve the fusion of gametes or change in the number of chromosomes. The offspring that get up by asexual reproduction from both unicellular and multicellular organisms inherit the whole set of genes in their single parent. Asexual reproduction is the number one shape of reproduction for single-celled organisms including archaea and bacteria.
