According to the Big Bang theory of the origin of the universe, the universe has expanded from a hot dense state into a vast, cooler state. What would be considered scientific evidence supporting this theory?A) Galaxies are moving toward each other.
B) Galaxies are moving away from each other.
C) Cosmic background X-ray radiation was detected in space.
D) The existence of common elements throughout the universe.

Answers

The correct option is option B, Galaxies are moving away from each other

It was discovered by Edwin Hubble in 1920, that galaxies are moving away from each other in proportion to the distance between them. The greater the distance at which a galaxy  exists, the faster is the distance with which it is moving away. Hubble established the Hubble’s constant which establishes expansion rate which is also helpful in determining the age and size of the universe.

In a zygotic life cycle:_________A. Haploid cells form gametes that fuse to produce thick-walled diploid zygotes capable of surviving stressful conditions.
B. There is an alternation of generations.
C. The zygote undergoes meiosis and produces many heat-resistant spores that increase the population size and aid in dispersal.
D. Haploid cells form spores that fuse to produce thick-walled zygotes capable of surviving stressful conditions.
E. none of the choices provided.

Answers

Answer:

a. Haploid cells form gametes that fuse to produce thick-walled diploid zygotes capable of surviving stressful conditions.

Explanation:

The zygotic life cycle is exhibited by fungi and protists mostly. In these organisms, the multicellular organism is haploid. Haploid cells form gametes by mitosis. The haploid gametes are fused together to form the diploid zygote. Zygote mostly develops a thick wall to survive the unfavorable growth conditions. This zygote represents the only diploid phase of the life cycle of these organisms. Meiosis in zygote forms the haploid organism under favorable conditions.

Which is not a way that ancient people classified plants and animals? By using binomial nomenclature
By taste
By use
As beneficial or poisonous

Answers

The correct answer is - By using binomial nomenclature.

The ancient people were using their senses and their experiences in the defining of the plant and animal species. This was due to lack of technology, so they used what they had at disposal. Thus the binomial nomenclature is out of question for usage for the ancient people since they were nowhere near the technological level needed to perform such a thing and use it in their daily lives.
Since they're ancient, I'm guessing they didn't classify by using binomial nomenclature.
