Which of the following was one of the first instruments that prehistoric people probably used?A. Lyres
B. Tambourines
C. Guitars
D. Voices

Answers

Out of the following choices given, the first instrument used by the prehistoric people was their voices. The correct answer is D.

Answer:

Option (D)

From the remains of musical instruments that are collected by the archaeologists, scientists have predicted that the sound was first generated consciously, along with the creation of arts such as wall paintings, clay statuette during the time between 60,000 BC and 30,000 BC.

The human voice was usually considered to be the first musical instrument discovered by humans. In the initial period, people often used their hands to clap so that a clear rhythm can be obtained.

Archaeologists have collected early instruments such as whistles, pipes, and flutes that are made up of wood as well as from the bones of animals. Some of the old instruments include 'Tjurunga' and 'Harp'.

Thus, the human voice was considered to be the first instrument that prehistoric people probably have used.

hence, the correct answer is option (D).

The equations summarize the process of fertilization. Which equation represents fertilization? haploid + diploid = diploid
diploid + haploid = haploid
haploid + haploid = diploid
diploid + diploid = diploid

Answers

The answer is haploid + haploid = diploid.

Fertilization is the process in which two gametes (one male and one female) fuse which first creates a zygote and then leads to the development of an embryo. Germ cells are cells that give rise to the gametes - either egg cells (female gamete) or sperm cells (male gamete). Germ cells are the only cells that can undergo both mitosis and meiosis. They are diploid cells present in gonads. After meiosis haploid gametes are produced. Thus, in fertilization two haploid gametes fuse (n+n) and form diploid zygote (2n).

Answer:

C) haploid + haploid = diploid

What about Earth allows it to maintain bodies of water? a)moderate tempatures b)comet crashes c)tides d)mountains

Answers

The correct answer is (a.) moderate temperatures. The moderate temperatures allow Earth to maintain bodies of water into its normal state. Changes in the bodies of water in terms of volume and structure would change due to the change in temperature.

What allows the earth to maintain bodies of water are moderate temperatures, as shown in option A.

What are water bodies?

Rivers.
Lakes.
oceans.
Lagoons.

The earth's ability to maintain its water bodies is due to moderate temperatures, which allow this water to remain in a liquid state and pass through a cycle that maintains it. If the earth were a very hot planet, water bodies would completely evaporate. If the earth were very cold, the bodies of water would freeze.

Aim on how does the dominant hand and non-dominant hand react to stimulus

Answers

The dominant hand will most probably be faster to react and will also react more strongly in comparison to the non-dominant hand. The reason for this is that our dominant hand tends to be better at reacting towards stimuli in comparison to our non-dominant hand.
