When α helices and β sheets are described as being amphipathic, it means that they have one side or face that is predominantly polar, with the other side being predominantly hydrophobic. Option A is the correct answer
This means that the α helices and β sheets have distinct regions or sides with different chemical properties. One side of the helix or sheet is composed of polar amino acids, which have charged or polar functional groups that interact favorably with water molecules. These polar regions are hydrophilic, meaning they have an affinity for water.
On the other side, there are hydrophobic amino acids that have nonpolar or hydrophobic side chains. These hydrophobic regions do not interact well with water and tend to avoid contact with it. Instead, they tend to interact with other hydrophobic regions or residues in the protein or form a core in the protein structure.
Option A is the correct answer as it accurately describes the amphipathic nature of α helices and β sheets, where one side is predominantly polar (hydrophilic) and the other side is predominantly hydrophobic.

¿Qué puedo hacer para que mis hijos tengan un ambiente sano, alimentos y recursos naturales suficientes?
Answer:
proteger el medio ambiente mediante la utilización de energías renovables, crear conciencia a través del uso sustentable de los recursos naturales, disminuir el consumo, reciclar y fomentar la utilización de compuestos biodegradables
Explanation:
La cultura del descarte en conjunción con el aumento creciente en la población mundial ha conducido a graves problemas ecológicos que afectan actualmente a la sociedad tales como, por ejemplo, el cambio climático, el cual plantea una preocupación muy seria acerca de las condiciones en las que recibirán nuestro planeta jóvenes y futuras generaciones. La mejor manera de garantizar un ambiente limpio, saludable y sostenible es fomentando el uso de energías renovables y simultáneamente reduciendo al mínimo el consumo innecesario de recursos (como por ejemplo, a través del uso eficiente del agua o electrodomésticos de bajo consumo energético). También reciclar materiales, utilizando materiales biodegradables y evitando compuestos no reciclables (tales como plásticos) representan buenas ideas para un mañana sin riesgos ambientales.

Glycolysis requires an input of energy. What molecule provides this energy?
a) glucose
b) ATP
c) NAD+
d) ADP
Answer:
B
Explanation:
Glycolysis requires an input of 2 ATP molecules to produce 4 ATP molecules. It results in a net worth of 2 ATPs.
The option (B) is correct. ATP
What do you mean by ATP?
Adenosine triphosphate (ATP) is the source of energy for use and storage at the cellular level. The structure of ATP is a nucleoside triphosphate, consisting of a nitrogenous base (adenine), a ribose sugar, and three serially bonded phosphate groups.
Moreover, adenosine triphosphate is an organic compound that provides energy to drive many processes in living cells, such as muscle contraction, nerve impulse propagation, condensate dissolution, and chemical synthesis.
Therefore, ATP can be used to store energy for future reactions or be withdrawn to pay for reactions when energy is required by the cell. Animals store the energy obtained from the breakdown of food as ATP. Likewise, plants capture and store the energy they derive from light during photosynthesis in ATP molecules.

What is a main difference between Mercury and Neptune?
Mercury is an inner planet with a thicker atmosphere and a longer year than Neptune.
Mercury is an inner planet with a thinner atmosphere and a shorter year than Neptune.
Neptune is an inner planet with a thicker atmosphere and a shorter year than Mercury.
Neptune is an outer planet with a thinner atmosphere and a shorter year than Mercury.
Answer:
B because Mercury's orbit is 88 days and Neptune's is 164 earth years
Mercury is an inner planet with a thinner atmosphere and a shorter year than Neptune.
What is Mercury and Neptune?
Since 2011, Neptune has spent 12 years in the sign of Pisces, which it rules and enjoys being in. Mercury spends just 15 to 60 days in each sign of the zodiac, but because of the Mercury retrograde, they come together and hang out for a while.
This is incredibly uncommon. It may be said that Mercury, the hare, is enjoying a Long sleep with Neptune in a dreamy fog and has forgotten his responsibilities as a courier around the Earth.
When Mercury conjoined the Sun on March 14 at 24 degrees Pisces and then today, on March 25, when Mercury conjoined Neptune at 16 degrees Pisces, this was notably felt.
Therefore, Mercury is an inner planet with a thinner atmosphere and a shorter year than Neptune.

A liquid has a density of 11g/mL. If you have 35mL of the liquid, what would its mass be?
Answer:
use the equation below
Explanation:
density=mass/volume
A liquid has a density of 11g/mL. If you have 35mL of the liquid, the mass of the liquid will be 385 grams.
What is density?"Density is the mass per unit volume". Density is a scalar quantity. It is denoted by d and the symbol for density is given as rho, a Greek symbol. Density is calculated as mass divided by volume.
"Mass is the quantity of matter in a physical body". The product of the molar mass of the compound and the moles of the substance are defined as mass.
Volume is the space occupied by a three-dimensional object.
Given that, the volume of liquid is 35mL
The density of the liquid is 11g/mL
The mass to be calculated
The formula to calculate the mass is
mass = volume x density
mass = 35 x 11 = 385 grams
Thus, the mass of the liquid will be 385 grams

Explain why it is very important for the gametes to divide by meiosis. What could happen if the gametes accidentally divide by mitosis? can someone answer in a sentence!!
Meiosis is important because it ensures that all organisms produced via sexual reproduction contain the correct number of chromosomes. Meiosis also produces genetic variation by way of the process of recombination.
Explanation: Gametes are made via meiosis which produces cells with n=23 instead of diploid cells. If gametes were produced instead by mitosis each gamete would be diploid not haploid.

Chemical Weathering 5 facts about it
Answer:
5 Facts
Explanation:
1. When it comes to chemical weathering, it’s all about chemistry. By looking at the term “chemical weathering,” you can see that a chemical reaction causes something to break down or “weather.” That “something” is rocks and minerals.
2. In chemical weathering, rocks and minerals are reacting to acids, oxygen, carbon and water. That’s why no two rocks ever look exactly the same. It’s also the reason that we have those awesome looking caves and unique rock formations all over the world.
3. While chemical weathering creates nifty formations, the way it breaks down rocks also causes fractures in ancient structures like the Great Sphinx of Egypt. It also causes the surface to break down on gravestones.
4. Chemical weathering types can work separately, but they often work together to create landforms and break down minerals.
5. Acid rain caused by pollution such as factory and car exhaust is another agent of chemical weathering.
