Which is one reason why hydrogen is considered a better fuel source for cars? It is nonrenewable. It produces carbon dioxide. It emits no harmful emissions. It combines with water to produce electricity.
Answer:
I’m pretty sure it’s .D
Explanation:
Hydrogen is considered a better fuel it emits no harmful emissions.
Hydrogen:Hydrogen is consider as clean fuel, when it is consumed with fuel cell produces only water. It is produced from variety of domestic sources such as natural source and renewable source such as solar and wind.
Hydrogen fuel can be used in:
Renewable liquid fuelsgasified biomassgasified coalDieselOnce hydrogen gas is generated it produces electrical power in a fuel cell, emitting water vapor and air. Hydrogen's energy content by volume is low.
Hydrogen storage is a challenge because it requires high pressures, low temperatures, or chemical processes to be stored compactly. Hydrogen fuel should now be feasible and easily available so that people can easily buy it.
Therefore, Hydrogen is considered a better fuel it emits no harmful emissions.

Explanation:
blood vessels that contain valves and rely on skeletal muscles to move blood are called:
A) arterioles
B) veins
C) capillaries
D) arteries
and why!? thanks!!
Answer:
veins because they carry low pressured blood due to which there is more chance for backward flow of blood and to prevent that they contain valves.
hope it helped uh..
Answer:
B. Veins
Explanation:
Veins carry blood relying on the action of the skeletal muscle as the body moves. Veins have valves so blood flows in only one direction. Valves are not present in arteries. Arterioles is small and contains valves to prevent backflow of blood but does not rely on skeletal muscles. Capillaries don’t have any valves. The correct answer would be veins.

Based on the evidence of their embryos, which pair of phyla are most closely
related?
O A. Echinodermata and Annelida
O B. Mollusca and Arthropoda
O C. Mollusca and Echinodermata
O D. Annelida and Chordata
Answer: B
Explanation:
AP*X
Invertebrates with an exoskeleton, segmented bodies, and paired jointed appendages are known as arthropods.
Molluscan animals have soft bodies that are triploblastic, bilaterally symmetrical, and coelomate. Malacology is the study of Mollusks. They are slow-moving invertebrates with a thin fleshy envelope or mantle that protects the visceral organs.

Recording the spread of the seafloor in the mid-Atlantic region d. Correlate the rotation of Earth to plate movement
Answer:
C. Recording the spread of the seafloor in the mid-Atlantic region
Explanation:
This seems to be the only logical answer. Since we are talking about a method in studying plate tectonics/movements, using evidence of it, seafloor spreading, would be the best idea out of the four.
Seafloor spreading is a geologic process in which tectonic plates—large slabs of Earth's lithosphere—split apart from each other.

How would you explain to an athlete why damaged joint ligaments and cartilages are so slow to heal following an injury?
Answer: They have little to no direct blood supply.
Explanation: “Ligaments and cartilage injuries are very common injuries for people who practice sports. Damaged joint ligaments and cartilage are slow to heal because these structures don't have a significant blood supply, which brings necessary fluid and nutrients to the injured place. These nutrients and fluids are essential for damage repairing. If ligaments and cartilage become injured, their limited blood and nerve supply result in a longer recovery and healing period.”
The reason why damaged joint ligaments and cartilages are so slow to heal
is as a result of little blood flow within them.
Cartilages and ligaments are connective tissues which help to connect
bones and other parts together. This part of the body has very little blood
flow and a result blood carrying nutrients aren't adequately supplied to the
region.
Different nutrients and compounds which promote healing and repair of
worn out tissues are found in the blood and failure to reach these regions is
why healing is slow.

While an important source of freshwater, groundwater is not as widely used as rivers and springs. This is a false statement because groundwater is widely used.
What is the use of ground water?The fresh water is present in lakes, springs, rivers, and ponds, and some remains as groundwater. Apart from this, water is present in the ocean and sea, but that can't be used for drinking purposes. The fresh water can have a wide range of uses, such as drinking, using in industry, taking baths, etc.
The groundwater is heavily used for drinking purposes, as this is considered to be less polluted. River and spring water are getting polluted due to the discharge of polluted water from industries. Ground water is misused, and due to heavy water loss, the amount of water keeps on declining. People from different areas are facing the issue of getting drinking water.
