The density of a white dwarf is
Answer:
The density of a white dwarf is 1 x 109 kg/m3.
Explanation:
A typical white dwarf is half as massive as the Sun, yet only slightly bigger than Earth. An Earth-sized white dwarf has a density of 1 x 109 kg/m3. Earth itself has an average density of only 5.4 x 103 kg/m3. That means a white dwarf is 200,000 times as dense.
1 x 10⁹ kg/m³ is the density of white dwarf. It is 200000 times denser than Earth. And it is the second densest object we know after neutron star.

How does ocean expansion occur?
Answer:
Global sea level has been rising over the past century, and the rate has increased in recent decades. ... The two major causes of global sea level rise are thermal expansion caused by warming of the ocean (since water expands as it warms) and increased melting of land-based ice, such as glaciers and ice sheets.

A. Cells that conduct electrical impulses throughout the body.
B. Thin projections that extend from a cell and connect to other cells.
C. An insulating lipid layer.
D. Cells in the brain that control hormone release.
Thanks!
Answer:D
Explanation: got it right
The neurons are the cells that conduct electrical impulse throughout the body. The correct option is A.
What is nerve impulse?The signal commutes along the height of a nerve fiber and results in neurotransmitter release.
Neurons are the basic units of the brain and nervous system; they are the cells that receive sensory input from the outside world and sending motor commands.
Nerves carry information along the neuron and all over the nervous system via nerve impulses.
Thus, the correct option is A.

Herbicides are chemicals that kill plants by interrupting important biological processes. Different herbicides affect different plant processes. The herbicide atrazine prevents the chemical reactions that use energy from sunlight.
A plant is sprayed with atrazine.
Exposure to atrazine causes an immediate decrease in the production of two substances in plant. Select the substance.
A. DNA
B. Carbon dioxide
C. Oxygen
D. Phospholipids
Answer:
oxygen because that's one of the substance that plants produce.
You can also do this by the process of elimination. Knowing that atrazine impedes the production of substances in plants, we know that it can't be DNA and Phospholipid. Carbon Dioxide is used by plant, not produced; thus, oxygen is the answer.
A herbicide is a type of pesticide that is used for controlling the weeds so that the plants can get nourishment. They are common weed killers used to clear taw waste groups and constructional areas.
These herbicides are used for different plants and prevents the chemical reaction that makes use of energy. The plants are sprayed with the chemical called atrazine which is used to decrease the production of oxygen.Hence the option C is correct.

List and describe 4 features of the ocean floor
Answer:
Humans beings haven't touched the ocean floor.but the features is -The deep ocean is dark, very cold and has tremendous pressure from the overlying water.Scuba divers can explore only to about 40 meters, while most submarines dive only to about 500 meters. Scientific research submersibles have explored the ocean’s deepest trenches, but most are designed to reach only the ocean floor.Today much of our exploration of the oceans happens using sonar and remotely operated vehicles.Features of the ocean include the continental shelf, slope, and rise. The ocean floor is called the abyssal plain. Below the ocean floor, there are a few small deeper areas called trenches. Features rising up from the ocean floor include seamounts, volcanic islands and the mid-oceanic ridges and rises.Which of the two growth models, exponential or logistic, would you say that the human population portrays?

Prokaryotes play essential roles in the environment and industry. Which statement describes the benefit of nitrogen fixation, a process that certain prokaryotes perform? (1 Point) a. Genetically-engineered bacteria synthesize drugs and chemicals. b. Bacteria clean up oil spills and or remove waste from water. c. Bacteria break down dead organisms and cycle materials back into the environment. d. Symbiotic bacteria on the roots of legumes help supply nutrients to the plant.
Answer:
d. Symbiotic bacteria on the roots of legumes help supply nutrients to the plant.
Explanation:
Symbiotic bacteria on the roots of legumes help supply nutrients to the plant by fixing atmospheric nitrogen done by nitrogen fixing bacteria. There are some bacteria present in the roots of plants which fixes atmospheric nitrogen and convert in available form to the plants and in exchange the plant provides food and habitat to the bacteria that performs nitrogen fixation.
A book is sliding along a desktop. Because the book is in motion, you know that the forces acting on the book are ______? What is the force acting against the book?
Answer:
Normal force, gravity and Friction.
Explanation:
The forces acting on the book are normal formal force which act or exerts by the table on the book while on the other hand, gravity is a force that acts in the downward direction. Friction is the force that acts against the motion of the book and is responsible for lowering speed of the book that is sliding on the surface of the table. If the friction is low between the book and table then the book moves easily on the surface.

oxygen transport in humans involves the bonding of oxygen with
A : white blood cells
b :platelets
C :Hormones
D Hemoglobin molecules
Answer:
i think it's d. hemoglobin molecules
Oxygen transport in humans involves the bonding of oxygen with hemoglobin molecules. Therefore, option (D) is correct.
Human oxygen transport is essential for delivering oxygen, a key gas needed for cellular respiration, to all tissues and organs. Haemoglobin molecules in red blood cells deliver oxygen.
Oxygen diffuses into the bloodstream and meets haemoglobin in the lungs. Oxyhemoglobin is formed when haemoglobin binds to oxygen molecules. Oxygen partial pressure and other factors affect reversible binding.
The heart pumps oxygenated blood via the circulatory system to tissues and organs. Oxyhemoglobin releases its oxygen, allowing cells to use it in cellular respiration to make energy. The mechanism efficiently supplies oxygen for metabolic needs. Life and physiological activities depend on this mechanism. Therefore, option (D) is correct.
