Answers

10% 

These light and heat energy are then used for photosynthesis and other cell processes.

Plant can go through photosynthesis because they contain chloroplasts.  A chloroplast is an organelle found only in plant cells and which enables photosynthesis to occur.

Insides chloroplasts, there are  found structures called thylakoids also known as grana or stroma. It is these thylakoids that contain chlorophyll, the green pigment that helps capture light energy from the sun which provides the fuel to run the first stage of photosynthesis.

The diagram shows an unpredicted change in the genetic material of two chromosomes. The change in DNA is called a A) mutation. B) replication. C) transcription. D) translation.

Answers

The unpredicted changes in the genetic material of chromosomes in a cell is known as Mutation. Mutations are the changes in gene caused by mutagens. Thus, the correct option is A.

What is Mutation?

Mutation can be defined as any change in the DNA sequence of a cell. These may be caused by mistakes during the cell division, or may be caused by exposure to DNA-damaging agents in the environment which are called Mutagens. Mutations can be harmful, beneficial, or have no effect.

Mutations can affect an organism by changing the phenotype or it can impact the way DNA of an organism codes the genetic information. When mutations occur in an organism they can cause termination of an organism or can be partially lethal.

Therefore, the correct option is A.

Earth's greenhouse effect is most directly related to the _____ cycle.a. argon
b. carbon
c. oxygen
d. nitrogen

Answers

carbon

reason being that if you've studied the carbon cycle, you know that carbon goes into the atmosphere and is absorbed by plants. but if we produce more CO2 than plants can absorb, it causes more rays from the sun to be concentrated to the earth, rather than being reflected away

Answer:

The answer is B. carbon Earth's greenhouse effect directly related to the carbon cycle hopefully this helps!

The ATP molecule shown consists of a base,__________, and a chain of three phosphates.

Answers

The ATP molecule shown consists of an adenine base, a ribose sugar, and a chain of three phosphates. ATP (adenosine triphosphate) is used in cells as a coenzyme for energy transfer. It plays a significant role in several biological processes such as cellular respiration (Krebs cycle or citric acid cycle) and fermentation.

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)

Explanation:

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).
