All macromolecules have carbon atom and the hydrogen atom.

<h3>What are macromolecules?</h3>

The term macromolecules refers to the molecules that are composed of smaller units. These smaller units are called monomers. The macromolecules that we are concerned with here are the macromolecules that could be found in the human body.

The biological macromolecules are often very large as we can see. This is because the number of units that are joined to form the macromolecules are usually very much. There are thousands of monomer molecules that are joined together to give proteins, lipids, carbohydrates and the nucleic acid macromolecules.

All the macromolecules have the carbon atom and the hydrogen atom. These are found across all the macromolecules. The carbohydrates are reducing sugars thus they contain the carbonyl bond. The carbonyl group is absent in lipids, nucleic acids, proteins, and amino hence they do not undergo carbonyl reduction reactions.

Answer:

A graph not only depends on the data that we are graphing, there are other important factors such as the units we use (here we have °C vs years, but we could have °F vs days and we would see a different graph, which represents the exact same information) , the scale we use (a lot of graphs are misleading because of the use of logarithmic scales, we need to be clear about the scales we use), where we put the zero of each axis (We usually use the intersection of both axes as the (0, 0) point, but this is not a necessary condition, we could manipulate our coordinate axis as we want) , etc.

So there are a lot of things that can impact on how we see the graph of the same data.

About the second answer, one could interpret from that graph that the actual temperature between the years 1880 and 2020 was around 14°C.

Scientists studied reproduction in the New Zealand mud snail. They wanted to determine whether reproducing sexually or asexually
lubasha [3.4K]

A hypothesis is a claim that expresses a relationship between variables. D) Asexual reproduction is advantageous over sexual reproduction because it decreases the snails’ need for social interaction.

<h3>What is a hypothesis?</h3>

A hypothesis is a scientific conjecture, not verified, that requires corroboration. It is a possibility, but not a fact. It is a claim of how it works a relationship between two or more variables.

The researcher hypothesizes in order to predict what is going on or what is expected to occur.

A hypothesis must express what is expected to occur in a perfectly comprehensive manner. There must be a logical relationship between the involved variables. It must be objective. Usually, it is written in the present time.

There are different kinds of hypotheses: descriptive, correlative, differentiative, or causative.  

In the exposed example, researchers wanted to determine whether reproducing sexually or asexually was more beneficial for the snails.

Options,

A) <em>Sexual reproduction is advantageous over asexual reproduction because it reduces the rate of mutation accumulation. </em>

The benefit of reproducing sexually is that the risk of mutation is lower.

B) <em>Asexual reproduction is advantageous over sexual reproduction because it allows the snails to produce more offspring.</em>

<em />

The benefit of reproducing asexually is that a higher number of descendants are produced, which increases reproductive success.

C) Sexual reproduction is advantageous over asexual reproduction because it allows for snails to have increased genetic variation.

The benefit of reproducing sexually is that it increases genetic variation.

D) Asexual reproduction is advantageous over sexual reproduction because it decreases the snails’ need for social interaction.

The benefit of reproducing asexually is that there is no need for social interaction.

Social interaction does not really benefit snails as a species. This is not a variable that might influence in a significant way snails.

However, variables like the mutation rate, variability, and the number of descendants are useful to test how they benefit or not the snails.  

The hypotheses that would least likely aid the scientists to answer the question is <u>option D</u>.

Which of the following is a disadvantage of wind as an energy source?
lesya692 [45]

Explanation:

Wind energy is one of the sources of renewable sources of energy that is environmentally friendly.

It uses wind power to generate other forms of energy mostly electricity.

Some of the drawbacks are:

  • Wind turbines pose serious threat to wildlife. It is common place to see dead birds in areas where wind power is being harnessed.
  • The quantity fluctuates from time to time. Since wind is an element of weather, it is not always in regular supply as desired.
  • The cost of constructing wind turbines can be very high a times.

Incorporation of _____, a neutral antibiotic, into a polyvinyl chloride membrane allows for the manufacture of an ion-selective
Alja [10]

The incorporation of valinomycin, a neutral antibiotic, into a polyvinyl chloride membrane allows for the manufacture of an ion-selective electrode that is highly selective for potassium.

<h3>How Valinomycin Ionophores Enter and Transport K+ across Model Lipid Bilayer Membranes?</h3>

  • A biomimetic lipid membrane attached to the surface of the gold electrode contained the cyclic peptide valinomycin.
  • The ionophore characteristics of the peptide were investigated using electrochemical impedance spectroscopy, and the conformation and orientation of the antibiotic valinomycin within the membrane were identified using polarization modulation infrared reflection absorption spectroscopy.
  • By forming a complex with potassium ions and an ion pair with a counter anion, valinomycin transports ions across the membrane, and the combination of these two techniques revealed novel information about the ionophore mechanism.
  • The ion pair is located inside the hydrophobic portion of the membrane and makes a little angle of around 22° with the surface normal.

Which part of the eye contains receptor cells that are sensitive to light?
Annette [7]
The lining of the back of eye containing two types of photoreceptor cells - rods - sensitive to dim light and black and white - and cones - sensitive to colour. A small area called the fovea in the middle of the retina has many more cones than rods.
