which of the following molecules is likely a carbohydrate?
a) H2O
b) C11H22O11
c) C2H17O2
A carbohydrate is a molecule that contains hydrogen and oxygen in a ratio of 2:1 like water.
The term carbohydrate simply means "a hydrate of carbon". This molecule can be broken up into carbon an water.
For this to be possible, the molecule must contain hydrogen and oxygen in a ratio of 2:1 as in water.
This is only possible in C11H22O11. The hydrogen to oxygen ratio is 2:1 hence the compound is a carbohydrate.

There are two types of reactions in photosynthesis: light-dependent reactions and light-independent reactions. A group of biology students creates a set of devices that will automatically measure the rates of both types of reactions. The light-dependent reaction rate is tracked by the rate of water uptake in plants, and the light-independent reaction rate is tracked by the rate of carbon dioxide gas uptake in plants. The students decide to measure the rate of the light-dependent reactions at noon, when the light is brightest, in a sunny room. They measure the rate of the light-independent reactions at 8:00 p.m. in a dark room under very minimal lighting conditions.
What is the most obvious critique of the students’ experimental design?
Answer:
The two stages of photosynthesis: Photosynthesis takes place in two stages: light-dependent reactions and the Calvin cycle (light-independent reactions). Light-dependent reactions, which take place in the thylakoid membrane, use light energy to make ATP and NADPH
Match the characteristics with the phylum. Tongue-shaped structure called radula for grasping food spongin fibers or spicules for support fleshy lobe-like structure called parapodia Porifera arrowRight Molluska arrowRight Annelida
Answer:
A Tongue-shaped structure called radula for grasping food --> MolluscaFleshy lobe-like structure called parapodia --> AnnelidaSpongin fibers or spicules for support ---> PoriferaExplanation:
Radula: This is an organ used in feeding by mollusks. It constitutes a highly developed feeding organ. The radula has is conformed of small teeth-like structures located in rows. Lateral teeth vary in shape and size. The movements of the radula during feeding are complexes acting as a scratcher on the surface to get the food.
Parapodia: These are characteristic lateral appendixes that emerge and extend from each of the body segments of invertebrates such as polychaetes. The typical parapodium is a fleshy prolongation more or less laterally comprised and is composed of a superior branch (notopodium) and an inferior branch (parapodium).
Spicules: Sponges (Poriferous) skeleton is composed of calcium carbonate and siliceous micro-structures called spicules. Their morphology is so varied that it is used in taxonomy for identification and classification.
There are different kinds of spicules:
- Monoaxonic spicule: needle-shaped, straights or curves
- Tetraxonic spicules: they have four prolongations
- Triaxonic or Hexaxonic spicules
- Poliaxonic spicules
Two terms can be applied to any of these spicules kinds:
- Megaspicules: They are elongated and compose the main architecture of the sponge skeleton
- Microspicules: Variable in shape and size, with ancillary functions
Sponges have few predators because of the spicule structures and their high toxicity. Many of them are capable of perforating soft tissues and producing urticant substances.
Which statement correctly describes a supersaturated solution?
A) it is possible to dissolve more solute into the solution
B) more solute than i normally possible is dissolved
C) the solution is made of pure solute and contains
D) it is not possible to dissolve more solute into the solution
Answer:
D) it is not possible to dissolve more solute into the solution
Explanation:
There are primarily three types of solutions: saturated solution, unsaturated solution and supersaturated solution.
A "saturated solution" is a solution in which you can dissolve a lot more solute. It has very little solute in it.
An "unsaturated solution" is a solution in which you can dissolve a little more solute although it has a lot of solute in it.
A "supersaturated solution" is a solution in which you cannot dissolve any more solute. It has the maximum amount of solute in it. This makes choice D as the answer.
Plants absorb nutrients from soil, and nutrients help plants grow. Which level of organization best describes this interaction between plants and soil?

if there is 13% guanine in a DNA molecule how much cytosine and thymine would there be ?
Answer:
13% cytosine
37% thymine
Explanation:
There are two types of nucleotides based on their structures - purines and pyrimidines.
The purines are adenine and guanine. The pyrimidines are thymine and cytosine.
Chargaff's rule states that the ratio of purines to pyrimidines in a molecule of DNA is 1:1
Therefore, the total number of A+G is the same at the total number of C+T.
All 4 bases together must equal 100% of the DNA molecule
If there is 13% guanine, and guanine always pairs with cytosine, there is also 13% cytosine.Together, that is 26% of the total sample.
100-26 = 74% of the total of adenine and thymine.
Since there are equal amounts of A and T, we know that the DNA sample is 74/2 = 37% thymine

Caverns most commonly form in limestone. So, the correct option is (C).
What is Limestone?Limestone is defined as a type of carbonate sedimentary rock which is the main source of physical lime and is composed mostly of the minerals calcite and aragonite, which are different crystal forms of CaCO₃. Limestone is formed when these minerals precipitate out of water containing dissolved calcium.
It is a known source of lime as calcium oxide used in steelmaking, mining, paper production, water treatment and purification, and plastic production. It also has major applications in the manufacture of glass and in agriculture.
A cavern is a natural opening in the Earth large enough for human exploration. This type of cavity is formed in many types of rocks and by many processes. The largest and most common caves are those formed by a chemical reaction between circulating groundwater and bedrock which is composed of limestone or dolomite.
Thus, Caverns most commonly form in limestone. So, the correct option is (C).

The behavior that occurs when a wave travels straight through a medium is known as
Answer:
If it is a single disturbance passing through a medium, then it is called a pulse.
Transmission occurs when a wave travels straight through a medium. Light transmits well through air, glass, and water.
What is transmission?As the name implies, transmission occurs when a wave moves from one medium to another. Distinct waves go through various media in different ways. The rate of transmission is sensitive to both the wave's and the medium's characteristics, as well as the frequency at which the wave is propagated.
Some examples of transmission are :
When ocean waves travel through a shallow area, they retain the majority of their original energy.Upon hitting a window, more than 95% of the light's energy is retained.Therefore, the behavior that occurs when a wave travels straight through a medium is known as Transmission.

describe how a plant takes in carbon dioxide from the air and mineral ions from the soil
Answer:
Plants take up essential elements from the soil through their roots and from the air (mainly consisting of nitrogen and oxygen) through their leaves. Nutrient uptake in the soil is achieved by cation exchange, wherein root hairs pump hydrogen ions (H+) into the soil through proton pumps.
Plants take in carbon dioxide from the air through their leaves and mineral ions through their root hairs
Plants take in carbon-dioxide through the atmosphere during photosynthesis in the presence of sunlight and gives out oxygen to the atmosphere in the process as well. while the mineral ions found in the soil are absorbed by a plant through its root hairs in the form of ions dissolved in water ( solutes ). these solutes are deposited in ground water by the humus soils which enables the absorption of the mineral ions by the plants.
Hence we can conclude that plants take in carbon dioxide from the air through their leaves and mineral ions through their root hairs.

13% cytosine
37% thymine
Explanation:
Chargaff's rule states that the DNA always has a 1:1 ratio of purine bases (the cytosine and thymine to pyrimidine bases (guanine and adenine).
If there is 13% guanine, then there must also be 13% of cytosine (since G pairs with C)
The total of guanines and cytosines is 26%, meaning the total of A + T is 100% - 26% = 74%. That means there are 74/2 = 37% of thymine.
