Why / how does hydrogen bonding help ice cubes float?

Answers

Answer 1

Answer:

First, we must understand:

What is Hydrogen Bonding?

Hydrogen Bonding is the interaction between Hydrogen atoms, with their molecules, due to the fact that their (Hydrogen atoms and bonds) are weak that even the other types of bonds are stronger.

(The other bonds are: covalent and ionic bonds)

(Hydrogen bonds are weaker than the average bonds listed above)

If you are to take how and why hydrogen bonds effect/affect ice cubes, we would have to look at how ice cube are formed. If you know, ice cubes can be created due to low temperatures (cold temperatures) making water into a solid. When ice cubes form into a sold, the spacing of the molecules become further apart, creating the density of the overall ice cube lighter than it was allowing it (ice cubes) to float.

Which abiotic factors would you expect to influence the growth of trees in the mountains?

Number of deer and insects
Types of trees and plants
Rainfall and the location on the mountain
Predator and prey population

Answers

I would have to say the answer to this would be “rainfall and the location on the mountain.” I say this because the options don’t really have anything to do with how they would influence the growth of trees in the mountains. Trees need water, i.e. rainfall, in order to grow. The location matters, as well. If the tree is in a spot has trouble getting water then it’s not going to grow as good as a tree that gets enough water, if that makes any sense. I hope this helps you.

Answer:

Rainfall and the location on the mountain

Explanation:

This is the answer because:

Rainfall highly helps the trees on the mountains grow. The location of a tree also matters a lot because it has to be in a spot where it can reach sunlight and lots of rain.

Therefore, the answer is Rainfall and the location on the mountain.

Hope this helps! :D

Answers

Answer:

plant cells have a rigid cell wall that helps it keep shape and animal cells don't

Answer:

Plant cells contain a cell wall to help give better structure and protection than animal cells. Plant cells also contain a large central vacuole that is used to store waste and water. Another thing is that plant cells have an organelle that preforms photosynthesis.

in what ways is ATP like a fully charged battery?

Answers

Answer:

ATP ATP can be compared to a fully charged battery because both contain stored energy, whereas ADP resembles a partially charged battery. Releasing Energy From ATP The energy stored in ATP is released when ATP is converted into ADP and a phosphate group.

Explanation:

The ATP molecule is comparable to a battery that can be recharged. It is ATP when ultimately charged. It's ADP when it's worn out. When the battery runs out, it is simply recharged rather than discarded.

What is ATP?

A vital "energy molecule" in all living things is adenosine 5′-triphosphate, also known as ATP and typically written without the 5′-. In particular, it is a coenzyme that transfers cells' energy by liberating its phosphate groups when it interacts with enzymes like ATP triphosphatase. The molecule comprises an adenine bicyclic system, a furanose ring, and a triphosphate chain.

The discovery of ATP was announced in 1929 by two research teams. It was isolated from mammalian muscle and liver by Cyrus H. Fiske and Yellapragada Subbarow at Harvard Medical School (Boston). Karl Lohmann discovered it in muscle tissues while working for the Kaiser Wilhelm Institutes in Berlin and Heidelberg.

Over the next 15 years, ATP separation from other sources came next. In 1987, Koscak Maruyama of Chiba University (Japan) provided a thorough analysis of ATP's discovery and structural elucidation.

Therefore, ATP is like a rechargeable battery because it can be recharged and discharged.

Explain why the population of clones would struggle to evolve if there was a major environmental change on the island.

Answers

The population of clones that struggle to evolve if there was a major environmental change on the island is :

-Lack of variations in the population as the clones are products of without fusion reproduction.

"Environmental change"

The population of clones will struggle due to lack of variations in the population as the clones are products of without fusion reproduction.

Without fusion reproduction will allow the parent organism to produce offspring that are exactly identical to the parent.

Also it will help in production of large number of progenies at a single time.

Therefore, the population of clones will struggle due to lack of variations in the population as the clones are products of without fusion reproduction.

how to find atomic mass number?
PHYSICS question

Answers

Answer:

Together,the number of protons and the number of neutrons determine an elements isotopes have slightly different mass numbers, the atomic mass is calculated by obtaining the mean of the mass numbers for its isotopes.

hope it is helpful....

To calculate the atomic mass of a single atom of an element, add up the mass of protons and neutrons. Example: Find the atomic mass of an isotope of carbon that has 7 neutrons. You can see from the periodic table that carbon has an atomic number of 6, which is its number of protons.

​A carbon atom has 6 protons and 6 electrons. Carbon has three naturally occurring isotopes, carbon-12, carbon-13, and carbon-14. Which of these statements is true about carbon and its isotopes? A.​All carbon atoms have six neutrons. B.​All carbon atoms have six protons and six electrons. C.​Atoms of all carbon isotopes have either more than 6 electrons or fewer than 6 electrons.

Answers

Answer:

The correct option is B

Explanation:

Isotopes of the same element have the same atomic number (number of protons) but different mass number. Hence, all the three naturally occurring carbon isotopes mentioned in the question have 6 protons each. Since the number of protons in a neutral atom is equal to the number of electrons in the same atom, each of these isotopes also have 6 electrons.

However, to determine the number of neutrons in each atom, the number of protons (atomic number) is subtracted from the mass number.

Hence, the number of neutrons in carbon-12 is 12 - 6 = 6

the number of neutrons in carbon-13 is 13 - 6 = 7

the number of neutrons in carbon-14 is 14 - 6 = 8

From the explanation above, it can be noted that the number of protons and electrons in isotopes of the same element are the same while the number of neutrons in these isotopes are different. Hence, the correct option is B

White blood cells are especially active when you are sick because their primary job is to fight off infections – often bacteria or viruses that do not belong in you. Once they locate the invader making you sick, they eat it and destroy it. What organelle do you think is plentiful in white blood cells?

Answers

Answer:

Lysosomes

Explanation:

Lysosomes are membrane bound organelles that contain degradative enzymes. They degrade worn-out cellular parts and may also be used by cells to degrade/destroy invading bacteria or viruses. Hence, since white blood cells are primarily responsible for fighting infections, it is expected that they have a high amount of lysosomes (which they indeed do have in high amount).

D) RNA polymerase is using a single strand of the DNA molecule as a template for mRNA production

Answer:

D) RNA polymerase is using a single strand of the DNA molecule as a template for mRNA production

Explanation:

During transcription, RNA polymerase uses DNA as a template to create a new molecule of mRNA via complementary base pairing

A) tRNA with anticodons is carrying amino acids to the ribosomes.  - this is not evidence of transcription but is instead evidence of translation

B) DNA polymerase is using both strands of DNA to produce multiple RNA molecules.  - this is false, DNA polymerase is the enzyme that performs DNA replication not transcription.

C) Ribosomes are reading mRNA molecules three nucleotides at a time to synthesis proteins  - this is not evidence of transcription but is instead evidence of translation

D) RNA polymerase is using a single strand of the DNA molecule as a template for mRNA production - this accurately describes the process of transcription.
