Advantages Of the asexual reproduction

The organism that reproduces asexually has the ability to take many different extensive forms that allow asexual reproduction to succeed in various environments?

The asexual reproduction is only performed in the organisms that often stay in one place, It does not need mobility, So, most plants have a great ability to create their offspring as this process doesn’t need to move to another place.

Asexual reproduction has a rapid increase of offspring which is very helpful in producing lots of offspring, It lets the plants make lots of offspring effectively which will help them in increasing their genes.

Disadvantages Of Asexual Reproduction

Most organisms that only perform the asexual reproduction process have less chance to adapt to the changes of the environment as they need stable environments.

Only one parent plant is required for the asexual reproduction, the new plants are identical to the parent so that good features will always be passed on, the chromosomes and genes of the parent will be copied, So, there will be genetic defects or the mutation in the offspring with no exception.

The asexual reproduction does not have the genetic diversity, there is less variation produced with the offspring, and the organism becomes less adapted to certain environmental changes, the entire communities will not be adapted to the harsh environment.

The asexual reproduction usually leads to struggle for the existence as well as the overcrowding, and the main distinction of asexual reproduction from the sexual reproduction is that there is no need for two parents as well as special cells to reproduce.

Explanation:

Answer:

true

Explanation:

The fatty acid chains are the uncharged, nonpolar tails, which are hydrophobic. Since the tails are hydrophobic, they face the inside, away from the water and meet in the inner region of the membrane.

The statement "the tail portion of the phospholipid molecule is hydrophobic" is definitely true.

Phospholipid may be defined as an amphipathic molecule that is constructed from four components. They are fatty acid, a platform to which fatty acids are attached, a phosphate, and an alcohol attached to the phosphate.

The molecule of phospholipid has a polar head and a non-polar tail. The polar head is known as hydrophilic and a non-polar tail is known as hydrophobic.

Such types of tails move away with water, hence they are significantly found at the inner side of the membrane and form a type of barrier.

These tails of phospholipids are typically uncharged which expel water and separates the internal contents of the cell from its outer environment.  

Therefore, the statement "the tail portion of the phospholipid molecule is hydrophobic" is definitely true.

The correct answer is -

Two methionine amino acids will be in the protein chain.

The protein will have five amino acids.

Explanation:

In protein synthesis, there are mRNA codons made up of the three bases known as triplet codons that form a specific amino acid during translation. There is a specific codon known as the starting codon that is AUG present at the beginning of almost every protein sequence and code for the methionine amino acid. UAG, UGA, and UAA are the stop codons if present at the end of the mRNA sequence and if any of these stop codons are present at the end of the sequence they do not produce any amino acid.

In this case, the mRNA sequence having 6 triplet codons AUG CCC UUU AUG GGG UAA where the first AUG is a start codon and code for the methionine and UAA is a stop codon and do not code for any amino acid therefore, the protein would carry only 5 amino acid and as there are two AUG so it has two methionine.

Answer:

Two methionine amino acids will be in the protein chain.

The protein will have five amino acids.

Answer:

B - by comparing DNA from the blood cells with DNA from suspects!

Explanation:

DNA fingerprinting is a laboratory technique used to establish a link between biological evidence and a suspect in a criminal investigation.

A DNA sample taken from a crime scene is compared with a DNA sample from a suspect.

If the two DNA profiles are a match, then the evidence came from that suspect. (from www.genome.gov )

Hope this helps! :]

A forensics expert has obtained a sample of human blood from a crime scene, DNA fingerprinting may be useful by comparing DNA from the blood cells with DNA from suspects, which is option B.

DNA fingerprinting is a technique used to identify individuals based on their unique DNA profiles, and by analyzing the sequence of nucleotides in an individual's DNA, forensic scientists can create a DNA profile that is unique to that individual. So to identify the person who left the blood at the crime scene, forensic scientists would analyze the DNA in the blood sample and create a DNA profile, and then find out the criminal based on the DNA fingerprinting.

Hence, DNA fingerprinting may be useful by comparing DNA from the blood cells with DNA from suspects, which is option B.

Any infectious disease (genetic, bacterial, and viral) can be prevented by vaccinations. Therefore, option D is correct.

Vaccinations are primarily designed to stimulate the immune system and provide protection against specific pathogens that cause diseases. They work by introducing harmless components of the pathogen, such as inactivated or weakened viruses or bacteria, or their components (antigens), into the body.

This exposure allows the immune system to recognize and mount an immune response against the pathogen without causing the actual disease.

Answer: C

Explanation:

A specific DNA segment is amplified via PCR from a complicated combination of starting material, commonly referred to as template DNA, hence option C is correct.

The reaction's simplicity and the relative case of the practical manipulation procedures are what's behind it. The reaction needs some knowledge of the flanking DNA fragment's sequence in order to be amplified.

Taq polymerase is the name of the heat-tolerant bacterium from which the DNA polymerase normally used in PCR was derived (Thermus aquaticus). T. aquaticus resides in hydrothermal vents and hot springs.

The primers are used in accordance with the sample or target DNA. The procedure, which entails numerous cycles in which copies are created, likewise uses DNA and Taq polymerase.

Therefore, the three fundamental phases are "denaturation," "annealing," and "extension."
