Answer:

c) Membrane lipids are amphipathic.

Explanation:

A cell can be defined as the structural, fundamental, biological and functional unit of life. Cells are found in all living organisms because they are the basic unit of life.

In a cell, the "workers" that perform various functions or tasks for the survival of the living organism are referred to as organelles. Some examples of cell organelles found in all living organisms such as trees, birds, and bacteria include; nucleus, mitochondria, lysosomes, ribosomes, chromosomes, endoplasmic reticulum, cytoskeleton, vesicles, golgi apparatus, and cell membrane.

Cell membrane is the wall of a cell and typically controls what leaves and enters the cell.

A general property of cell membranes is that membrane lipids are amphipathic. All the lipid molecules found in the cell membrane are amphipathic or amphiphilic, which means that they are "water loving" (hydrophilic) with a polar end or "water fearing" (hydrophobic) with non-polar end. Thus, membrane lipids have an end that's soluble in water (polar) while the other end is soluble in fat (non-polar).

The membrane lipids are amphipathic.  

• In the majority of cell membranes in animals, lipids, that is, fatty molecules forms about 50 percent of the mass of the cell.  

• All the molecules of lipid in a cell membrane are amphipathic, that is, they possess a polar end or hydrophilic and non-polar end or hydrophobic end.  

• The phospholipids are the most abundant lipids found in the cell membrane.  

• They have a polar head group and two hydrophobic hydrocarbon tails.  

• It is the amphipathic nature and shape of the molecules of lipids, which makes them to produce bilayers spontaneously.  

Thus, correct answer is option c, that is, membrane lipids are amphipathic.

Answer:

1. Molecular weight = 333.3 g/mol

2. Strenght = 2222.2 mg/L

Explanation:

First, we need to find molarity (M) from normality (N) as follows:

[tex] N = nM [/tex]      

Where n is the number of OH⁻ = 2

[tex] M = \frac{N}{2} = \frac{0.03}{2} = 0.015 mol/L [/tex]

Now, when the H₃X solution is neutralized with Ca(OH)₂ we have:

[tex]\eta_{H_{3}X} = \eta_{Ca(OH)_{2}} = M_{Ca(OH)_{2}}*V_{Ca(OH)_{2}} = 0.015*0.04 = 6 \cdot 10^{-4} moles[/tex]              

Hence, the molecular weight (MW) of H₃X is:    

[tex] MW = \frac{m_{H_{3}X}}{\eta_{H_{3}X}} = \frac{0.2 g}{6 \cdot 10^{-4} moles} = 333.3 g/mol [/tex]

Finally, we can calculate the strength (S) of this solution in ppm as follows:

[tex] S = \frac{m}{V} = \frac{200 mg}{0.050 L + 0.040 L} = 2222.2 mg/L [/tex]

Answer:

A physical change, such as a state change or dissolving, does not create a new substance, but a chemical change does. In a chemical reaction, the atoms and molecules that interact with each other are called reactants. In a chemical reaction, the atoms and molecules produced by the reaction are called products.

Answer:Static electricity can be created by rubbing one object against another object.

Explanation: This is because the rubbing releases negative charges, called electrons, which can build up on one object to produce a static charge

Answer: Bacteria, some insects, and fungal species are the decomposers of the dead and decaying matter.

Explanation:

The decomposers are the organisms which act and feed on the dead and decaying organic matter so as to obtain energy from it and degrade it to the simple forms that can be utilized by the plants. Bacteria, some insects and fungi that live in the soil and on the decaying matter. The fungi for example decay on the lignin present in the wood so helps in wood decomposition of trees. If the decomposer like fungi are absent the wood mass will not decompose and it will remain as waste and can be used by the plants in the form of nutrients.

The dark moths were better hidden from predators and therefore more of them survived and this allowed them to have offspring.

Answer:

The dark moths were better hidden from predators and therefore more of them survived and this allowed them to have offspring.

Explanation:

If all of the light colored trees disappeared and there are only dark colored ones, then that means that the light colored moths wouldn't be able to live long since their traits wouldn't match the environment. This then leads to the conclusion that dark moths would be better hidden since their trait fits their current environment and would let them be hid much better from predators. This would allow them to survive longer and eventually, reproduce.

Answer:

355Joules

Explanation:

The amount of heat absorbed can be calculated using the formula:

Q = m × c × ∆T

Where;

Q = amount of heat absorbed in joules

m = mass of substance in grams

c = specific heat capacity of solid (0.727 J/g°C)

∆T = final temperature - initial temperature (°C)

According to the information provided in this question;

Q = ?

m = 12.3g

∆T = 62.1°C - 22.4°C = 39.7°C

c = 0.727 J/g°C

Using Q = m × c × ∆T

Q = 12.3 × 0.727 × 39.7

Q = 355.001

Q = 355Joules

Hence, 355J of heat was absorbed

The  methanol are produced when 2.8 grams of carbon monoxide reacts with 0.50 grams of hydrogen gas is 3.6 grams. option B is correct.

Methanol is also known as methyl alcohol or wood spirit, it is the  long series of organic compounds called alcohols, having a methyl group (CH 3) attached with a hydroxy group (OH). Methanol was formerly made by the process of destructive distillation of wood.

Here, 2.8  grams of carbon monoxide reacts with 0.50 grams of hydrogen gas as there are 4 hydrogen molecules add 2.8 + 0.50 × 2 = 3.6 grams.

Therefore, methanol are produced when 2.8 grams of carbon monoxide reacts with 0.50 grams of hydrogen gas is 3.6 grams. option B is correct.
