Answer:

One reason is that agricultural plants are often grown in large quantities and are often monoculture crops, meaning that they are all the same species. This can make them more susceptible to pests and diseases, as these organisms can quickly spread through a monoculture crop and cause significant damage. Natural growth plants, on the other hand, are often more diverse and may not be as vulnerable to these types of problems.

Answer:

Adaptations to a common environment and examples of convergent evolution

Explanation:  

Convergent evolution is a process by which two independent and phylogenetically separated organisms, get to develop similar structures or behavior to survive. These structures make possible a better performance in a similar environment. These organisms are morphologically or ethologically similar in their whole bodies or just in parts.  

Convergent evolution occurs in different phylogenetic branches independently from each other. It results from the need of different organisms to adapt to a similar environment and to solve a problem from that particular ecological niche. Ecological pressures acting on them might be similar, modeling the organisms´ phenotype. Each evolutive branch ends by developing the same structures, which they both find effective in their environment.  

In the exposed example, Ichthyosaurs (reptile) and fishes are separated species on evolutive time, corresponding to different phylogenetic lineages. Both of them inhabit the same aquatic environment. Pressures of the habitat acted on them and modeling their phenotypes. These species need to adapt to living in water, moving, feeding, scaping, chasing, etc. So both species arrived at the same solution. They developed dorsal fins and tails, which are important to stabilize the body in the water while swimming, making it more hydrodynamic and getting to propel better.

D. mitosis

Explanation:

Mitosis is the process whereby the parent cell divides into two daughter cells that are identical.

Mitosis is the process by which a parent cell becomes two identical daughter cells. So, the correct option is (D)

Mitosis is the process in which cell duplication, or reproduction takes place. Wherein one parent cell gives rise to two genetically identical daughter cells. Mitosis is the duplication and distribution of chromosomes which carries the genetic information.

It is an important process in single celled eukaryotes as it is the mode of asexual reproduction. The main function of Mitosis is to produce more cells.

Life starts with single cell in multicellular organism which is formed from two gametes. Mitosis takes place one cell is divided into two cells as this single celled multicellular organism only carries genetic information in the form of DNA but not enough cells. These two cells further divide mitotically into four cells, then into 8 , then 16 and then 32.

It is essential to life because it give rise to new cells for growth and replacement of dead cells. It may take few minutes or some hours, depending on the type of cells. It depends on time, temperature and chemicals.

Thus, mitosis is the process by which a parent cell becomes two identical daughter cells. So, the correct option is (D).

Answer:

First, enzymes read the information in a DNA molecule and transcribe it into an intermediary molecule called messenger ribonucleic acid, or mRNA. Next, the information contained in the mRNA molecule is translated into the "language" of amino acids, which are the building blocks of proteins.

In transcription, the information in the DNA of every cell is converted into small, portable RNA messages. During translation, these messages travel from where the DNA is in the cell nucleus to the ribosomes where they are 'read' to make specific proteins.

Have a wonderful day! :-)

Answer:

Explanation:

The process of converting genetic information stored in DNA into functional proteins that can be used by cells is known as gene expression. This process is composed of several steps:

Transcription: The first step in gene expression is the transfer of genetic information from DNA to RNA. This is accomplished through the process of transcription, where an enzyme called RNA polymerase reads the DNA code and synthesizes a complementary RNA molecule. This RNA molecule is called messenger RNA (mRNA).

Splicing: Before the mRNA molecule is transported out of the nucleus, it may undergo a process called splicing. This process involves the removal of non-coding sequences of the mRNA molecule, leaving only the coding sequence, called exons.

Translation: After the mRNA molecule has been processed and is in the cytoplasm, it is translated into a protein by ribosomes. The ribosome reads the sequence of codons (groups of three nucleotides) in the mRNA molecule and uses this information to assemble a chain of amino acids. The amino acids are linked together through peptide bonds to form a functional protein.

Post-translational modification: Once the protein is produced, it may undergo further modification, such as folding into its final 3D shape or modification by the addition of chemical groups. These modifications are important for the proper functioning of the protein.

In summary, gene expression is the process by which the genetic information stored in DNA is transcribed into mRNA, processed, and then translated into functional proteins in the cytoplasm. These proteins carry out the functions that are essential for the survival and functioning of cells.

(A) The answer to the initial value problem is given by \(\(y = (x^2 + 1)e^x\)\), where \(\(y' - y = 2xe^{2x}\)\) and \(\(y(0) = 1\)\).

(B) The resolution to the initial value problem can be expressed as \(\(y = \frac{2x - (\pi - 1)}{\sin(x)}\)\), where \(\(y' + \cot(x)y = 2\csc(x)\)\) and \(\(y\left(\frac{\pi}{2}\right) = 1\)\).

(A) To solve the initial value problem:

\(\[y' - y = 2xe^{2x}, \quad y(0) = 1\]\)

We can use an integrating factor method. To begin, let us express the equation in its standard form:

\(\[y' - y - 2xe^{2x} = 0\]\)

The integrating factor \(\(I(x)\)\) is given by \(\(I(x) = e^{\int -1 \, dx} = e^{-x}\)\).

To obtain the solution, apply the integrating factor to both sides of the equation and perform the multiplication.

\(\[e^{-x}(y' - y) - 2xe^{2x}e^{-x} = 0\]\)

This simplifies to:

\(\[e^{-x}y' - e^{-x}y - 2x = 0\]\)

Now, observe that the expression on the left-hand side represents the derivative of \(\((e^{-x}y)\)\) with respect to \(\(x\)\).

Using this observation, we can rewrite the equation as:

\(\[\frac{d}{dx}(e^{-x}y) - 2x = 0\]\)

Integrating both sides with respect to \(\(x\)\), we get:

\(\[e^{-x}y - \int 2x \, dx = C\]\)

where \(\(C\)\) is the constant of integration.

Integrating \(\(\int 2x \, dx\)\), we have:

\(\[e^{-x}y - x^2 + C = 0\]\)

To find the constant \(\(C\)\), we use the initial condition \(\(y(0) = 1\)\).

Substituting \(\(x = 0\)\) and \(\(y = 1\)\) into the equation, we get:

\(\[e^{0} \cdot 1 - 0^2 + C = 0\]\)

\(\[1 + C = 0\]\)

\(\[C = -1\]\)

Substituting \(\(C = -1\)\) back into the equation, we have:

\(\[e^{-x}y - x^2 - 1 = 0\]\)

Finally, we can solve for \(\(y\)\) by isolating it:

\(\[e^{-x}y = x^2 + 1\]\)

\(\[y = (x^2 + 1)e^x\]\)

(B) To solve the initial value problem:

\(\[y' + \cot(x)y = 2\csc(x), \quad y\left(\frac{\pi}{2}\right) = 1\]\)

We can use an integrating factor method. To begin, we will rewrite the equation in standard form:

\(\[y' + \cot(x)y - 2\csc(x) = 0\]\)

The integrating factor \(\(I(x)\)\) is given by:

\(\(I(x) = e^{\int \cot(x) \, dx} = e^{\ln(\sin(x))} = \sin(x)\).\)

Apply the integrating factor to both sides of the equation and perform the multiplication.

\(\[\sin(x)(y' + \cot(x)y) - 2\csc(x)\sin(x) = 0\]\)

This simplifies to:

\(\[\sin(x)y' + \cos(x)y - 2 = 0\]\)

Now, observe that the expression on the left-hand side represents the derivative of \(\((\sin(x)y)\)\) with respect to \(\(x\)\). Using this observation, we can rewrite the equation as:

\(\[\frac{d}{dx}(\sin(x)y) - 2 = 0\]\)

Integrating both sides with respect to \(\(x\)\), we get:

\(\[\sin(x)y -\)\(\int 2 \, dx = C\]\)

where \(\(C\)\) is the constant of integration. Integrating \(\(\int 2 \, dx\)\), we have:

\(\[\sin(x)y - 2x + C = 0\]\)

To find the constant \(\(C\)\), we use the initial condition \(\(y\left(\frac{\pi}{2}\right) = 1\).\)

Substituting \(\(x = \frac{\pi}{2}\)\) and \(\(y = 1\)\) into the equation, we get:

\(\[\sin\left(\frac{\pi}{2}\right) \cdot 1 - 2\left(\frac{\pi}{2}\right) + C = 0\]\)

\(\[1 - \pi + C = 0\]\)

\(\[C = \pi - 1\]\)

Substituting \(\(C = \pi - 1\)\) back into the equation, we have:

\(\[\sin(x)y - 2x + (\pi - 1) = 0\]\)

Finally, we can solve for \(\(y\)\) by isolating it:

\(\[\sin(x)y = 2x - (\pi - 1)\]\)

\(\[y = \frac{2x - (\pi - 1)}{\sin(x)}\]\)

\(\(y = \frac{2x - (\pi - 1)}{\sin(x)}\).\)

An allele is best described as a version of a gene. Option A is correct answer.

Genes are segments of DNA that contain instructions for the development and functioning of living organisms. Each gene can exist in different forms, called alleles.

For example, let's consider a gene that determines eye color. This gene can have different alleles, such as brown allele, blue allele, and green allele. Each allele represents a different version or variant of the gene.

The different alleles of a gene can lead to variations in traits or characteristics. In the case of eye color, individuals with two copies of the brown allele will have brown eyes, individuals with two copies of the blue allele will have blue eyes, and individuals with one copy of the brown allele and one copy of the blue allele will have a mix of brown and blue eyes.

So, the correct answer is A. A version of a gene. An allele represents different versions of a gene that can result in variations in traits or characteristics.

In summary, pre-mRNA is the precursor to mature mRNA and requires processing to remove introns and add modifications. Mature mRNA is the final product that can be translated into proteins.

The pre-mRNA in the nucleus of a eukaryotic cell is the initial transcript of a gene that undergoes processing to become a functional mature mRNA. Here's a comparison between the two:
1. Length: Pre-mRNA is longer than mature mRNA. It contains both coding and non-coding regions, whereas mature mRNA only contains the coding regions (exons).
2. Introns: Pre-mRNA contains introns, which are non-coding sequences. These introns are removed during mRNA processing, resulting in a mature mRNA with only the coding sequences (exons).
3. Processing: Pre-mRNA undergoes several modifications, including 5' capping, 3' polyadenylation, and splicing, to become mature mRNA. These modifications ensure stability, facilitate translation, and remove non-coding sequences.
4. Export: Pre-mRNA remains in the nucleus during processing, while mature mRNA is exported to the cytoplasm, where it can be translated into proteins by ribosomes.
In summary, pre-mRNA is the precursor to mature mRNA and requires processing to remove introns and add modifications. Mature mRNA is the final product that can be translated into proteins.
