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.

Why can the more complex sugar cellulose store more energy than the sugar
glucose?
A. Cellulose is made by plants.
B. Cellulose is smaller than glucose.
C. Cellulose has more chemical bonds.
D. Cellulose contains hydrogen atoms.
Answer:
Cellulose has more chemical bonds
Explanation:
It is complex carbohydrates molecule and stores thosands of energy as in glucose
The statement (C) is correct. The cellulose has more chemical bonds.
What do you mean by cellulose?Cellulose is an organic compound with the formula ₙ, a polysaccharide consisting of a linear chain of several hundred to many thousands of β linked D-glucose units. Cellulose is an important structural component of the primary cell wall of green plants, many forms of algae and the oomycetes.
Moreover, cellulose, a tough, fibrous, and water-insoluble polysaccharide, plays an integral role in keeping the structure of plant cell walls stable. Cellulose chains are arranged in microfibrils or bundles of polysaccharide that are arranged in fibrils (bundles of microfibrils), which in turn make up the plant cell wall.
Hence, cellulose is an insoluble dietary fibre consisting of glucose polymers present in all cell walls of plants.

PLEASE HELP ME!! ASAP Why is it so difficult to tell the impact of pollution in the deep ocean region?
Explanation:
THE OCEANS ARE so vast and deep that until fairly recently, it was widely assumed that no matter how much trash and chemicals humans dumped into them, the effects would be negligible.
hope it helped
All forms of pollution eventually taint water. Air pollution contaminates lakes and oceans. An underground stream, a river, and ultimately the ocean could all become contaminated due to land contamination.
What is the impact of pollution in the deep ocean region?The consequences of the toxins aren't usually obvious or simple to spot. Only in the cases of marine debris, man-made noise, and acidification by atmospheric CO2 can cause and effect be clearly shown.
The unfavorable climate makes it difficult to study the ocean floor. Instruments like sonar can be used to pollution study the seafloor in an indirect manner.
In contrast to mapping the land, the sea floor can't be directly measured from space using radar, since the water there absorbs the radio signals.
Therefore, With the aid of unique vehicles, it may be directly researched. To the ocean floor, certain vehicles transport scientists and their equipment.

Answer:
False
Explanation:
EDGE 2021
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.

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.

A.heavy metals promote biofilm formation in humans
B.heavy metals stimulate some microbes to reproduce even more
C.heavy metals are toxic to many organisms besides microbes
D.heavy metals can assist with virus attachment to host cells

The correct answer is - option C.
Explanation:
Heavy metals can alter the physiological and biochemical qualities or nature of the microbes or microorganisms. For instance, Chromium is able to denature the proteins of microbes and may cause oxidative damage.
Using heavy metals to control the microbe growth can be very dangerous as the ions of these heavy metals bind themselves to amino acid containing sulfur tightly and accumulate in the cells. This can be very toxic the most of the organisms besides the microbes.
