How do radio telescopes help advance our knowledge of our universe?
Answer:
Raido telescopes can sense signals way out in space seening things that we havent seen yet therefore futhering our knowlege of the universe
Explanation:
To investigate naturally occurring radio radiation from stars, galaxies, black holes, and other celestial phenomena, we utilize radio telescopes.
What are radio telescopes?They may also be used to send and receive radio waves that are reflected from the planets in our solar system.
Planets, comets, massive clouds of gas and dust, stars, and galaxies may all be seen with radio telescopes as they point toward the skies. Astronomers can discover information about these objects' composition, structure, and motion by examining the radio waves they emit.
We can learn more about these hot regions, which emit radio waves, with the use of radio telescopes. Our solar system's planets also have radio personalities.
Therefore, radio telescopes display the motion of the gas clouds that whirl around Uranus and Neptune, and the north and south poles of Jupiter emits radio waves.

Which of the following converts food into energy for the cell?
Vaculoe
Cytoplasms
Mitochondria
Cell Membrane
Mitochondria converts food into energy for the cell.
Mitochondria convert food into energy for the cell. Option 3 is correct.
Mitochondria are often referred to as the "powerhouses" of the cell because their primary function is to generate energy in the form of adenosine triphosphate (ATP) through a process called cellular respiration. This process involves the breakdown of glucose and other organic molecules to produce ATP, which is the main energy currency of the cell.
Inside the mitochondria, there are specialized structures called cristae, which increase the surface area available for cellular respiration. The mitochondria have an outer membrane and an inner membrane, with a space called the intermembrane space in between. The inner membrane contains proteins and enzymes involved in the electron transport chain, a key step in ATP production.
During cellular respiration, glucose is broken down through a series of biochemical reactions, such as glycolysis, the citric acid cycle (also known as the Krebs cycle), and the electron transport chain. These reactions occur in the mitochondria, specifically in the matrix (fluid-filled region) and on the inner mitochondrial membrane. Through these processes, the energy stored in glucose is gradually released, and ATP is synthesized.
The ATP produced by the mitochondria is then used by the cell to power various cellular activities, including metabolism, active transport, muscle contraction, and synthesis of macromolecules. Without functional mitochondria, cells would not be able to efficiently convert food into energy, and vital cellular processes would be impaired.

1) A delta is receiving sediment at a faster rate than it is subsiding. What will happen to the delta?
A. It will grow.
B. It will sink.
C. It will stay the same.
D. It will erode away
Answer: Option D.
It will erode away.
Explanation:
Delta refer to landform that is formed when the river and sediments empty itself into the oceans, another river or land.
When a Delta is receiving sediments at faster rate than it is subsiding, it will erode away because as the water and sediments continue to empty itself in it, it will accumulate large some, and when it has exceeded the capacity it can hold, it will break into distributaries channels that allows water and sediments to flow and branch off from the mainstream river into the land or another place.

A pea plant with wrinkled peas is crossed with a pea plant with smooth peas. All of the offspring produced have wrinkled peas. What can be inferred about the wrinkled pea trait?
A) It is recessive.
B) The smooth and wrinkled traits are codominant.
C) The plant is a hybrid.
D) It is dominant.
Answer:
D. It is dominant
Explanation:
A dominant trait will always be the one portrayed as long as it is in the genes. Think of it as an override. It is the reason 2 brown-eyed people can have a blue-eyed child. The Punnett square is always the first thing I think of when it comes to genes.

Explanation:
A teacher has two cubes of sugar that are both the same size and shape. He adds cube A to a beaker filled with 100 mL of water, and the cube completely dissolves in the water. He then places cube B on a glass dish over a flame. He keeps the dish over the flame until cube B has turned completely black. Once cube B has cooled off, he adds it to another beaker filled with 100 mL of water. Cube B does not dissolve in water.
What does this demonstration indicate?
Answer:
Burning sugar results in a chemical reaction
Explanation:
Flammability, odor, and density are just a few examples of characteristic properties of a substance. A chemical reaction occurs when molecules interact with one another and the molecules change. For example burning sugar results in a chemical reaction because the properties of cube B changed when it was burned. This change in solubility shows that cube B must be a different substance than cube A because of the chemical reaction that occurred when cube B was burned.
Answer:
Burning sugar results in a chemical reaction
