The phospholipid head is hydrophilic which means it has an affinity for water. And it is true.

<h3>What is phospholipid , its component and how come it is hydrophilic?</h3>
  1. Phospholipid contains of a head and a tail , the head part of phospholipid consist of phosphate group and for further clarification the tail part of phospholipid consist of fatty acids.
  2. As we know already phosphate group that is OH- is negatively charged which clearly which its head is going to be polar .
  3. Since its polar , its hydrophilic. There is a specific function performed by phosphate group that cannot be filled by other compound present simultaneously.
  4. Phosphate group grabs a role to provide space to other compounds too.

Explain why lime is added to lakes. Refer to the problem that exists and what lime does to the lakes.
aalyn [17]

Explanation:

Lime is added to lower the acidity of lakes when pH levels go too low.

Acidic environment is harmful to aquatic ecosystems. Acidity causes some minerals, such as phosphorus and calcium, in the water to become unavailable to aquatic organisms like plants and fishes ( This means the water hardness is reduced). The low nutrients cause stress and death in the aquatic environment lowering biodiversity.  Applying lime raises the pH to neutral levels and improves the health of the aquatic life in the lake. This also improves economic activities in the lake like fishing.

Brilliant_brown [7]

Answer:

<h2>8.89 g/mL</h2>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume} \\

From the question we have

density =  \frac{24}{2.7}  \\  = 8.88888...

We have the final answer as

<h3>8.89 g/mL</h3>

Hope this helps you

The isotope of an unknown element, X, has a mass number of 79. The most stable ion of this isotope has 36 electrons and has a 22
Tema [17]

Answer:

A) False

B) True

C) True

D) True

Explanation:

A) False. If the charge of the atom is +2 means that you have two protons more than number of electrons. If you have 36 electrons you must have <em>38 protons.</em> Also, the electrons are not in the nucleus.

B) True. The isotope of X contains 38 protons, two more than the electron number.

C) True. The mass number is the number of protons + number of neutrons.

If the mass number is 79 and there are 38 protons you must have 41 neutrons.

D) True. You can now the identity of the atom with the number of protons that is the same than atomic number. The strontium, Sr, is the atom with 38 as atomic number.

I hope it helps!
