Given what we know, we can confirm that the explanation for the situation described is that the blue star must be moving toward Earth and the red star away from Earth.
How do we explain this?This has to do with a phenomenon known as the doppler effect. This effect explains how we can perceive a star as red or blue depending on its distance and on whether or not it's moving towards or away from us. When an object moves away from us, the wavelengths of the light it emits are stretched, making the object appear red. However, when it moves towards us, this increases the wave frequency that reaches us and we observe it as blue.
Therefore, we can confirm that the explanation for the situation described is that the blue star must be moving toward Earth and the red star away from Earth.

The only type of human cell that is never replaced is ___. *
Answer:
The only type of human cell that is never replaced is Nerve cells.
Hope this helps you. Do mark me as brainliest.
The only type of human cell that is never replaced is nerve cell.
What is a nerve cell?Neurons are in charge of receiving sensory input from the outside world, sending action potentials to our muscles, and transforming and relaying electrical signals at every step in the process.
The nerve cell is the basic unit of communication in the nervous system (neuron). The cell body, a major branching fiber (axon), and numerous smaller branching fibers comprise each nerve cell (dendrites).
They do not divide in any way. There are only two exceptions to this rule: only two specific areas of the brain can produce new neurons. However, for the most part, the brain is unable to replenish dead neurons.
Thus, nerve cells are the ones that never gets replaced after getting injured.

In one of the first steps in Prophase I of meiosis,
A) the cell divides into four daughter cells.
B) the chromatids separate and move to opposite ends of
the cell.
C) half of the chromosomes are made inactive.
D) homologous pairs of chromosomes form tetrads
Answer:
D) homologous pairs of chromosomes form tetrads
Explanation:
During prophase I, the homologous chromosomes condense and become visible as the x shape we know, pair up to form a tetrad, and exchange genetic material by crossing over.
how would this affect the cells made from the cell cycle? passage: timmy has a disease that effects his cell cycle, it causes the S phase (part of interphase) to not work correctly.
Answer:
No cells are produced.
Explanation:
If the S phase of cell cycle did not work properly, the cells produced are abnormal or no cells are produced because no extra copy of chromosomes are present for cell division. If there is no extra copy of chromosomes is present in the cell, the cell will not go to the G2 phase and as a result the cell cycle is remain incomplete. So that's why we can say that no cells are produced if S phase did not work properly.
Scientists have studied a fruit fly, Drosophila, to better understand early embryonic development and have discovered that the cell cycle changes as embryonic development proceeds. Model A represents the first 13 cell cycles after fertilization, which only includes two phases. Model B represents cell cycles 14 through 16, which are more complex and include a G2 phase. The figure shows two circular models, labeled Model A and Model B, that represent the cell cycle of fruit flies after fertilization. Model A represents cell cycles 1 through 13, and it contains two phases. Model B represents cell cycles 14 through 16, and it contains three phases.
What of the following explains the advantage of a G2 phase during embryonic development?
A Cells can undergo the cell cycle more quickly with a G 2 phase.
B Cells can replicate more DNA with a G2 phase.
C Cells are checked for DNA damage before entering mitosis with a G2 phase.
D Cells are able to produce two new daughter cells with a G2 phase.
Answer:
C. Cells are checked for DNA damage before entering mitosis with a G2 phase.
Explanation:
G2 phase is very important phase of cell division in which cells are checked for DNA damage before entering mitosis with a G2 phase as well as correct duplication of the DNA is also verified and cell proteins that are necessary for cell division are also produced. This phase comes after S stage in which replication of DNA occurs so this G2 phase check the damages before starting of mitosis.
True or false: All herbivores are autotrophs.
Answer:
false
Explanation:
Autotrophs, organisms that produce their own food, are the first trophic level. These include plants and algae. Herbivores, which eat autotrophs, are the second trophic level. Carnivores, organisms that consume animals, and omnivores, organisms that consume both plants and animals, are the third trophic level.

Benny uses a compass to navigate his way through the woods when he
is carnping. The needle on the compass reacts to Earth's magnetic field
by always pointing north. Which part of Earth is responsible for creating
its magnetic field?
A. Cilist
B. inner core
C. mantle
D. outer core
Answer
Outer Core
Because of the weight of the melting moving metal creates energy
Our planet is shielded from cosmic radiation and charged particles from our Sun by the magnetic field, which is created by the motion of molten iron in the Earth's core. It also offers the framework for compass navigation. Thus, option D is correct.
What role of outer core of earth in magnetic field?Radiative heating and chemical differentiation have caused the Earth's outer core to be in a state of turbulent convection.
The convective kinetic energy is transformed into electrical and magnetic energy through a mechanism that is somewhat similar to a naturally occurring electrical generator.
The magnetic field is not produced by the earth's core, since metals lose their magnetic characteristics at high temperatures.
Therefore, Because of the weight of the melting, moving metal creates energy.

Mom has type O blood. Dad has type AB blood. What percentage of their kids will inherit type B blood?
Answer:
50%
Explanation:
Type A blood and type B blood are both dominant over type O blood.
A B
O AO BO
O AO BO
As is demonstrated by the Punnett square, the children's genotypes will either be AO or BO. Since type O blood is recessive, no child will have O blood, as other dominant alleles are present. 50% will have type A blood and 50% will have type B blood.

Can anyone help me write hydroelectric essay
INTRODUCTION:
BODY:
CONCLUSION:
Please I really have bad life
Answer:
A competitive firm’s marginal revenue always equals its average revenue and price. This is because the price remains constant over varying levels of output. In a monopoly, because the price changes as the quantity sold changes, marginal revenue diminishes with each additional unit and will always be equal to or less than average revenue. A conclusion is the last paragraph of your essay, or, if you’re writing a really long essay, you might need 2 or 3 paragraphs to conclude. A conclusion typically does one of two things—or, of course, it can do both: Summarizes the argument. Some instructors expect you not to say anything new in your Hydro-power is the energy harnessed from running water-streams, rivers or any other artificial or natural water flow. It is one of the oldest method of energy production. Even in the medieval period, people used to derive energy from water wheels. The contribution of hydel power in the world energy production scenario is immense and ever-increasing.
Hydro-electricity now contributes nearly 7% of global electricity production when only 15.3 percent of the global exploitable hydro-electric potential is being used. Ever increasing awareness of ecology and social costs of hydro-plant construction failed to debar the increasing use of hydro-electricity.
