D.Sucrose

Answer:

uses the energy of sunlight to convert water and carbon dioxide (reactants) into high-energy sugars and oxygen (products).

Explanation:Summarize what happens during the light-dependent reactions of photosynthesis. ... NADP+ molecules pick up the high-energy electrons along with H+ ions to become NADPH.

Most of the light energy absorbed during photosynthesis is used to generate ATP and NADPH in the light-dependent reactions, which are later used in the Calvin cycle to produce carbohydrates, effectively storing solar energy as chemical energy.

During photosynthesis, most of the light energy is converted into chemical energy. This transformation begins when sunlight is absorbed by chlorophyll, a pigment in the thylakoid membranes of the chloroplasts. A photon strikes photosystem II initiating the process where energy is transferred through an electron transport chain and is used to pump hydrogen ions into the thylakoid space, establishing an electrochemical gradient.

The hydrogen ions flow through ATP synthase, a process known as chemiosmosis, to form ATP, an energy carrier molecule. Photosystem I absorbs a second photon, leading to the formation of NADPH. Both ATP and NADPH are then utilized in the Calvin cycle to create sugar molecules. Ultimately, the light energy absorbed by plants is stored as chemical energy in carbohydrates, serving as fuel for life on Earth.

The number of cells produced in a week can be calculated using the formula 2^n, where n is the number of generations. Since a plant cell completes the cell cycle in 24 hours, the number of cells produced in a week would be 128 cells.

Explanation:

The number of cells produced in a week can be calculated using the formula 2^n, where n is the number of generations, and each generation represents a 24-hour cell cycle. Since a plant cell completes the cell cycle in 24 hours, we can assume that each day is equivalent to one generation. Therefore, the number of cells produced in a week would be 2^7, which equals 128 cells.

Answer:

Primary structure and quaternary structure because the heat energy will disrupt only the weaker interactions which causes the secondary and tertiary structure to break down.

Explanation: sorry no explanation :(

Among the four levels of protein structure, only the primary structure remains after denaturing.

The primary structure, which is the sequence of amino acids in the protein, survives because it's held together by sturdy covalent bonds.

Proteins have four hierarchical levels of structure: Primary, Secondary, Tertiary, and Quaternary.

However, only the primary structure of a protein can be maintained after a denaturing process.

Denaturing events, such as changes in temperature or pH, disrupt the interactions that hold the secondary, tertiary, and quaternary structures together.

Conversely, the primary structure, which refers to the sequence of amino acids in a protein, is held together by covalent bonds that remain intact during denaturation.

Answer/Explanation :

A heterozygous cat has a genotype Hh

A hairless cat has a genotype hh

When crossed, the results could be any of the following:

Hh (with hair)

hh (hairless)

There is a 50:50 chance or 1: 1 ratio that the offspring will have hair.

Final answer:

In a genetic cross involving cats where hair is dominant over hairlessness, a heterozygous male cat (Hh) mated with a hairless female cat (hh) results in offspring that are predicted to have a 1:1 ratio of haired (Hh) to hairless (hh) genotypes.

Explanation:

The question regards a genetic cross concerning hairlessness in cats, a trait determined by a single gene with two alleles: hair (H) is dominant over no hair (h). When a heterozygous male cat (Hh) is mated with a hairless (hh) female cat, we are examining a simple Mendelian cross to determine the offspring's potential genotypes.

The parents' genotypes in this scenario are as follows:

This cross results in a Predicted offspring phenotype ratio of 1:1, where 50% of the offspring are expected to be heterozygous with hair (Hh) and 50% are expected to be hairless (hh).

Answer:

Fission Hypothesis

Explanation:

This theory proposes that the Moon was once part of the Earth and somehow separated from the Earth early in the history of the solar system. The present Pacific Ocean basin is the most popular site for the part of the Earth from which the Moon came.

This theory was thought possible since the Moon's composition resembles that of the Earth's mantle and a rapidly spinning Earth could have cast off the Moon from its outer layers.

However, the present-day Earth-Moon system should contain "fossil evidence" of this rapid spin and it does not. Also, this hypothesis does not have a natural explanation for the extra baking the lunar material has received

Answer:False

Explanation:You're supposed to have numerically more smaller units than bigger units, since a lot of these smaller units are combined to create a single larger unit.

The given statement is False because a larger quantity is not divided by multiples of ten when it needs to be converted to a smaller quantity.

We multiply a larger quantity with the multiples of ten to convert it to a smaller unit during unit conversion.

For example, if you need to convert 3-kilo meters into meters -

You know that 1 km = 1000 meters,

So, to convert, let's consider x meters = 3 kilometers.

[tex]\frac{1}{1000} = \frac{3}{x}[/tex]

[tex]x = \frac{3 * 1000}{1}[/tex]

[tex]x = 3000[/tex] meters

Another example – you need to convert 2 milligrams (mg) into micrograms,

We know that 1 mg = 1000 micrograms

[tex]\frac{1}{1000} = \frac{2}{x}[/tex]

[tex]x = \frac{2*1000}{1}[/tex]

[tex]x = 2000[/tex] micrograms

This proves that, whenever you need to convert a higher unit into a lower unit, you need to multiply it by multiples of 10. Therefore, the given statement is False.

Answer:

DNA      ATG  CGC ATT AGT GCA  GGA CAG TAG

mRNA   UAC  GCG UAA UCA CGU CCU GUC AUC

tRNA     AUG  CGC AUU AGU GCA GGA CAG UAG

Protein Met  Arg    Ile    Ser    Ala   Gly   Gin   Stop    

Explanation:

The given is a DNA sequence. The next step to this one is transcribing it into a mRNA sequence. When you transcribe DNA to RNA, the main difference between RNA and DNA is that RNA does not have a THYMINE (T) base. So what do we do?

The base pairs would be:

G - C        T - A

C -G         A - U

                U - A

So keep this in mind. Let's take the first one codon (codon is a group of 3 bases):

A T G        

U A C

A transcribes to U

T transcribes to A

G transcibes to C

So that would be your first codon.

The next part wi=ould be translation. Now in translation, a specific amino acid codes for a specific codon. They are brought by tRNA, which has a anti-codon that codes for the amino acid it carries.

Let's take that same codon we transcribed earlier:

ATG

UAC

AUG

Looking at the chart, first look at the first letter, then match it up with the row it corresponds to.

So it falls under A, so look at the row of A.

The next step is to look at the column the second letter corresponds to, following the same row you started in.

Last would be the row within the column you identified that corresponds to the third letter of the codon.

As you can see you wil end up in the box:

AUU

AUC

AUA

AUG

The higlighted sequence is the codon we are examining and based on the box, you can see that it is the Met. So this would be your first amino acid, and this is also known as the start codon by the way.

Answer: D. Thr

Explanation: The bases Adenine- Cytosine-Uracil present in the mRNA strand can be written as ACU. From the above diagram, there are four codons that codes for threonine and they are ACU, ACC, ACA and ACG. Thr is the abbreviation for the amino acid Threonine.

Answer:

A. Competition can limit or deplete resources

Final answer:

Competition for abiotic and biotic resources can limit or deplete these resources, affecting their availability in an ecosystem. This can result in harm to competing organisms, influence community dynamics, and alter species distribution.

Explanation:

When organisms and populations compete for abiotic and biotic resources, the impact can be quite significant. Competition can limit or deplete resources, which affects the availability of these resources to both the competing organisms and others in the ecosystem. For instance, plants competing for sunlight, water, and nutrients can reduce the availability of these resources for other species. This competition can harm one or both of the competing organisms, particularly if they are of the same species (intraspecific competition) or of different species (interspecific competition).

An invasive species like kudzu, by competing for light, can outcompete and thus limit the growth of trees. This is an example of how competition can lead to ecological imbalances. In the broader picture, competition impacts not just the individuals directly involved but can also affect community dynamics and the distribution of various species in a habitat.

Considering the options provided, the correct answer is A. Competition can limit or deplete resources.

The option that best describes the structure of the molecules that make up proteins is D. Carboxyl group + amino group + side chain.

Proteins are made up of amino acids, which are molecules that contain a carboxyl group (-COOH), an amino group (-NH2), and a side chain (R). The carboxyl group and amino group are the reactive groups of amino acids, and they are responsible for the bonding of amino acids together to form proteins.

The side chain of an amino acid can vary in structure and chemical properties. This variation is what gives proteins their different properties and functions.

Besides storing genetic information, nucleic acids helps in

Understanding diseases

Creation of proteins

Transmission of information

Explanation:

Understanding diseases

Knowledge about the nucleic acids and their mechanism of action helps in understanding the causes of a disease and the possible cure for the disease. A genetic disease is caused when there is a faulty gene, which is made up of nucleic acids, is present in the genome. These genes will make faulty RNA's which will result in the establishment of faulty proteins. Hence, by having understanding about nucleic acids, diseases can be studies and cured.

Creation of proteins

The information from the DNA is coded by the mRNA which is used to make proteins.

Transmission of information

Apart from storing information, the nucleic acids such as the DNA are also involved in the transmission of information.

Nucleic acids, besides storing genetic information, are instrumental in the synthesis of proteins. They work to construct proteins based on the instructions carried by the DNA. Additionally, they play a part in regulating cell processes and help in energy production.

Nucleic acids, in addition to their principal role in storing genetic information, play several other vital functions in our bodies. Primarily, they are instrumental in the synthesis of proteins, which are the building blocks of cells. DNA, or deoxyribonucleic acid, carries the instructions for the production of these proteins, while another nucleic acid known as RNA (ribonucleic acid) works to construct the proteins based on these instructions.

Further, RNA also functions in other capacities, such as acting as a messenger (mRNA) that conveys the genetic code from the DNA to the ribosomes, sites of protein synthesis. Additionally, transfer RNA (tRNA) and ribosomal RNA (rRNA) both play critical roles in protein synthesis. Nucleic acids also play a part in regulating cell processes and help in the formation of ATP (adenosine triphosphate), the main energy source for many cellular processes.
