water canexistinthreestates;liquid,solidandgases.

Explanation:

At temperature below zero degree Celsius, water exists as a solid but as it absorbs temperature from Its surroundings, it undergoes melting and turns into liquid water. More application of heat makes it boil leading to the evaporation and vapourisation of water molecules( note: evaporation occurs at all temperature).

Water molecules binding to other polar molecules is calleda. surface tension
b. transpiration
c. adhesion
d. cohesion

Answers

Answer: Adhesion

Explanation:

Adhesion can be defined as the property to water molecules by which it gets attached to other molecules is known as adhesion.

As water molecules is polar in nature they gets attracted towards polar molecules only. So, the one polar molecules(water) gets attached to another polar molecules by adhesion.

This property of water allows it to move from one place to another. The water from soil move to upper part of the plant by this property.

Hence, the correct answer is adhesion.

What is not contained in our blood?A. Blood Plasma
B. Leukoctyes
C. Erythrocytes
D. Lymph

Answers

i think it might be lymph, but its not one of the first two

Our blood contains blood plasma, leukocytes, and erythrocytes but does not contain lymph. Lymph is a separate body fluid, transported by the lymphatic system.

Blood consists of several components: blood plasma, leukocytes (white blood cells), and erythrocytes (red blood cells). Blood plasma is a yellowish liquid component of blood that holds the blood cells of whole blood in suspension. It makes up about 55% of the body's total blood volume. Leukocytes are the cells of the immune system that are involved in protecting the body against both infectious disease and foreign invaders. Erythrocytes, or red blood cells, are cells present in blood in order to transport oxygen. On the other hand, lymph, although a body fluid, is not a part of the blood. It is mainly composed of white blood cells and is transported by the lymphatic system, separate from the circulatory system that transports blood.

6. If an object is an irregularly shaped solid and it is dropped into a graduated cylinder andit displaces 25 mL of water and has a mass of 50 grams what is the density of this
irregular shaped object?

Answers

Answer:

d = 2 g/mL

Explanation:

Given that,

Water displaced by an object in a graduated cylinder, V = 25 mL

Mass of the object, m = 50 g

We need to find the density of this irregular shaped object. It is given by mass per unit volume. So,

$d=(m)/(V)\n\nd=(50\ g)/(25\ mL)\n\nd=2\ g/mL$

So, the density of the object is 2 g/mL.

Protein phosphorylation is commonly involved with all of the following excepta. activation of receptor tyrosine kinases.
b. activation of protein kinase molecules.
c. activation of G protein-coupled receptors.
d. regulation of transcription by signaling molecules.

Answers

Protein phosphorylation is not involved in activation of G protein coupled receptor.

Further Explanation:

Roles of Protein phosphorylation are :

To involve in signal transduction.
To help in membrane transport .
To regulate cell cycle.

G- protein coupled receptor is activated through the external signals in the forms of ligand.

In this, ligand binds to the active site and cause conformation changes in receptor and active G- protein.

Final answer:

Protein phosphorylation is a key process in many biological functions but it is not directly involved in the activation of G protein-coupled receptors. Those receptors are activated by the binding to a specific signaling molecule, not phosphorylation.

Explanation:

Protein phosphorylation is a biochemical process that adds a phosphate group to a protein molecule, significantly affecting its function. Indeed, protein phosphorylation is involved in the activation of receptor tyrosine kinases, the activation of protein kinase molecules, and regulation of transcription by signaling molecules. However, phosphorylation is not directly involved in the activation of G protein-coupled receptors. Instead, these receptors are activated by binding to a specific signaling molecule or ligand, leading to a cascade of signaling events within the cell.
