Why is the polarity of water molecules and hydrogen bonding essential to adhesion and cohesion?

Answers

Answer 1
Cohesion and surface tension keep the hydrogen bonds of water molecules intact and support the item floating on the top. ... This is because the water molecules are attracted to the charged glass walls of the capillary more than they are to each other and therefore adhere to it.
Answer 2

Some properties like Polarity makes water a good solvent, cohesion helps in stick water molecule to itself while adhesion helps it to stick with other surfaces. Water have surface tension due to hydrogen bonding.

What are the difference between adhesion and cohesion ?

when two similar molecule come closer adhesion occur where as in cohesion two similar molecules face the force of attraction.

Adhesion is the force of attraction observed between the water molecules and xylem vessels while Cohesion is unrestrained among water molecules.

Capillary action and meniscus are the effects of adhesion while  Surface tension, meniscus and capillary action are the effects of cohesion.

The major forces responsible for adhesion are electrostatic or mechanical forces while Cohesion is the result of hydrogen bonding and Van der Waals forces.

A strong adhesion can lead to spread of liquid all over the surface while  cohesion forms water droplets.

What is the variable that affects enzyme function in the example of phosphofructokinase-1?

Answers

Answer:

This question is incomplete

Explanation:

The question is incomplete because the example referred to was not stated. However, phosphofructokinase-1 is a key enzyme in glycolysis; it converts/phosphorylates fructose-6-phosphate to fructose-1,6-bisphosphate in the presence of ATP to release ADP. It is a regulatory enzyme in this pathway (glycolysis) because it's function can be affected by an increased ATP to ADP ratio which inhibits the enzyme (phosphofructokinase-1) and indeed glycosis itself.

Give the two ways nitrogen can be fixated so plants can use it to grow.

Answers

[tex]\huge\mathfrak\red {Answer:}[/tex]

Fixation

Nitrogen in its gaseous form (N2) can’t be used by most living things. It has to be converted or ‘fixed’ to a more usable form through a process called fixation. There are three ways nitrogen can be fixed to be useful for living things:

Biologically:

Nitrogen gas (N2) diffuses into the soil from the atmosphere, and species of bacteria convert this nitrogen to ammonium ions (NH4+), which can be used by plants. Legumes (such as clover and lupins) are often grown by farmers because they have nodules on their roots that contain nitrogen-fixing bacteria.

Through lightning:

Lightning converts atmospheric nitrogen into ammonia and nitrate (NO3) that enter soil with rainfall.

What are the key difference between Independent and dependent Variable ?

The variable whose values are changed by researcher to get desired outcome  is called an independent variable.

The variable, by changing its values to reciprocate change in the values of the independent variable is called the dependent variable.

The independent variable is act as  the experiment controller whereas, the dependent variable act as experiment measure.

An independent variable is a cause whereas the dependent variable is an effect of that cause.

we can say in a linear regression, ‘y’ denotes dependent variable while ‘x’ denotes independent variable.

An independent variable does not rely on anything, while the dependent shows the effect, due to changes in independent variable.

Thus option A is correct.

An adult panda bear must eat at least 30 pounds of bamboo in a day. There are 12 adult pandas living in part of a bamboo forest 360 pounds must available each day.

Why does panda only eat bamboo?

Panda comes under the specialist because its eats only bamboo because it's present abundantly and Thus they don't have to fight with other animals to get it.

Bamboo is rich in fibre but has less nutrients, so pandas have to eat 20 to 40 pounds of the elements every day just to get by.

Explanation:

because it is a polysaccharide

Glycogen because it is a polysaccharide which provides long-term energy storage. So, the correct option is A.

What is Glycogen?

Glycogen is defined as a multi-branched polysaccharide of glucose that serves as energy storage in animals, fungi and bacteria which is the main storage form of glucose in the human body.

The body mainly uses glycogen stores in the liver to help regulate blood glucose which is sugar levels where the body normally regulates blood glucose mainly with the hormones glucagon and insulin. When the blood sugar level becomes too low, which is called hypoglycemia, the pancreas releases more glucagon.

Thus, Glycogen because it is a polysaccharide which provides long-term energy storage. So, the correct option is A.
