Answer: B
Explanation:
• Nerve cells (neurons) carry the message from the stimulated receptors to the correct effectors.
• A sensory neuron carries the message from the receptor to the central nervous system (the spinal cord and brain).
• A motor neuron carries the message from the central nervous system to the effector.
• This is a reflex arc.

Answer:
6, 5, 4, 2, 1, 3
Explanation:
Transcription refers to the process of the formation of RNA molecules from DNA molecules using DNA strands as a template.
Only one strand out of two DNA strands is involved in the process and the strand is known as coding strand which runs in the direction of 5' to 3'.
The process of transcription takes place in the following sequence:
1. Helicase enzyme binds to the DNA and unzips the two strands of DNA. This opens the helices of the DNA and the DNA gets open.
2. RNA polymerase binds to the promoter attached to the DNA and forms the single strand.
3. The RNA nucleotides form complementary base pairs with the DNA and the RNA strand. A new complementary strand is made using complementary base pairing.
4. DNA helicase unzips the DNA and RNA hybrid.
5. The DNA and RNA get separated and the mRNA molecule formed in the nucleus exits the nucleus.
6. The two-strand of DNA is again joined via complementary base-pairing rule.

Answers
Answer:
Human activities increases the concentration of oxygen in the atmosphere.
Explanation:
Human is not responsible for the balance of oxygen gas in the atmosphere because human takes oxygen from the environment for the production of energy in the process of respiration. Plants are the key factor for maintaining the oxygen concentration in the atmosphere. Human activities are the main reason of increasing carbon-dioxide and other harmful gases in the atmosphere and increases the air pollution and change in climate occurs.

The diagram below shows the Moon's orbit around Earth. Letters A, B, C, and D represent four positions in the Moon's orbit.
What is the approximate length of time it takes the Moon to travel from position A to position C?
1 day
14 days
28 days
31 days
Answers
Answer:
14 days is the correct answer. Since it takes 27(approx) days to complete one revolution of the earth and will take (27/2=14) days to complete half of the revolution I.e. A to C.
The orbit of the Moon around Earth is shown in the diagram below. Four locations in the Moon's orbit are represented by the letters A, B, C, and D.
How long does it typically take the Moon to move from position A to position C?
The Moon takes 28 days to go from location A to position C, which is a rough estimate. The Moon is at perigee, or its closest point to Earth, at position A. The Moon is at its apogee, or furthest point from Earth, at location C. Even though the Moon's orbital speed varies, it does take about 28 days to go from perigee to apogee. The Earth's orbit around the Sun and the Moon's orbit are both inclined.
This indicates a tilt between the orbital planes of the Earth and the Moon. The Moon's location with relation to the Sun consequently shifts throughout time. The Moon appears to "wax" and "wane" in the night sky because of this. The 28-day synodic period of the Moon accounts for the Moon's shifting positions with respect to the Sun.
Therefore, it may be concluded that it takes the Moon 28 days to roughly travel from place A to position C. This is due to the Moon's relatively slow orbital motion, which takes around 28 days to complete from perigee to apogee and from one place in relation to the Sun to another.

(please answer in simple words i don't even understand the question)
Answers
Answer:
During the process of the type of cloning known as Somatic Cell Nuclear Transfer (SCNT), once the nucleus is removed from the egg cell, blunt and sharp pipette both are used. The purpose of the blunt pipette is to hold the egg cell in position whereas the sharp pipette penetrates the cell to take the nucleus out by sucking it - a process known as "enucleation". This nucleus is discarded. Rather, this nucleus is replaced by a nucleus taken out from a somatic cell (same way as described before) of the same organism.

5. A majority of the moths were a lighter gray. With the changing color bark they were seen more by predators.
6. Adaption caused the first darker moths to appear because they learned they needed to blend into the new tree bark color.

What can scientists infer about the period of very early Earth from the fossilized remains of trees found under a lake?
Answers
Answer:There is a theory that terrestrial plants evolved from aquatic plants through a process of natural selection. Thus, by finding fossils of plants under the river, scientists may conclude that this theory is correct and that these fossils represent the ancestors of terrestrial plants.
The emergence of plants that survive on earth is a very important milestone for the planet, it is believed that these plants have evolved from green algae called Chlorophyta that have survived in marshy areas that had alternating periods of flooding and drought.Then the discovery of these fossils, through scientific experiments may conclude that the theory is correct
Explanation:
Answer:
The fossil record is the record of life on earth preserved in rock as fossils. The fossil record provides evidence of where types of plants and animals lived, how long they lived, how they died, and how they changed. It also tells us about Earth’s early environment and how it changed. The fossil record helps determine the age of rock formations by looking at how deep the fossils are buried in the rock. When a fossil is found above another fossil in a rock formation, the deeper fossil are considered older.
