(brainliest if right!) How is the dispersive model different from the semiconservative model of DNA replication?

1. In the dispersive model, each strand of both daughter molecules contains a mixture of old and newly synthesized DNA, and in the semiconservative model, each new double helix consists of one old and one new strand.
2. In the dispersive model, the old double helix is degraded, and in the semiconservative model half of its nucleotides are used in the construction of two new double helices.
3. In the dispersive model, one of the two resulting double helices is made of two old strands, and in the semiconservative model the other is made of two new strands.
4. In the dispersive model, one strand of the new double helix is made of DNA, and in the semiconservative model the other strand is made of RNA.

I believe they are the third trophic level. Please tell me if i'm wrong!

Answer:

Mendel's law of dominance states that in a heterozygote, one trait will conceal the presence of another trait for the same characteristic. ... The recessive allele will remain “latent,” but will be transmitted to offspring by the same manner in which the dominant allele is transmitted.

What is the law of segregation- The law of segregation ensures that a parent, with two copies of each gene, can pass on either allele. Both alleles will have the same chance of ending up in a zygote. In sexually reproducing organsisms, the genome is carried in two identical copies. A copy was inherited from each parent, in the form of a gamete

The given diagram basically represents a cladogram. The correct option is D.

A cladogram is a type of diagram that depicts the evolutionary relationships between organisms.

It is a branching diagram in which the nodes represent the descendants' most recent common ancestor. The cladogram is based on the organisms' shared characteristics or traits.

These characteristics, which can be physical or genetic in nature, are used to classify organisms into clades.

Clades are groups of organisms that share a common ancestor, and they are represented on the cladogram as branches.

The organisms are more closely related the closer the branches are to each other. Cladograms are commonly used in biology to study organisms' evolutionary histories.

Thus, the correct option is D.

Answer:

Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction. During reproduction, when the sperm and egg unite to form a single cell, the number of chromosomes is restored in the offspring.

Answer:

The purpose of mitosis is the creation of diploid somatic cells and the purpose of meiosis is the creation of haploid sex cells.

Explanation:

Mitosis takes place in somatic, or body cells, and meiosis takes place in gametes, or sex cells.  The purpose of mitosis is growth and repair, while the purpose of meiosis is creating gametes with half the normal number of chromosomes and is for reproduction.  Mitosis goes through Interphase, Prophase, Prometaphase, Metaphase, Anaphase, Telophase, and Cyokinesis once to produce two genetically identical diploid somatic daughter cells.  Meiosis goes though that twice (Meiosis I and Meiosis II) to produce 4 genetically unique haploid gametes.  It has stages (Prophase, Metaphase, Anaphase, and Telophase) such as Prophase I and Prophase II because meiosis occurs twice.  Another difference is that mitosis happens throughout your life and meiosis occurs before females are born and throughout a males life.  

Answer: Sexual reproduction provides genetic diversity because the sperm and egg that are produced contain different combinations of genes than the parent organisms.

Explanation:  Each resulting cell, or gamete, resulting from meiosis has only half the amount of DNA as the parent cell.

Explanation: A.P.E.X.

Gene therapy and gene splicing are separate but linked processes. A new organism can be created by cutting and recombining genetic material from two separate sources, a process known as gene splicing.

It is a technique that scientists utilise in the lab to develop new organisms with desired features. On the other side, a healthy gene is introduced into the patient's cells during a medical process called gene therapy to treat diseases and disorders.

Gene splicing and gene therapy share certain similarities despite their distinctions. Both procedures entail the modification of genetic material, frequently derived from several sources, in order to produce the desired outcome.

The goal of gene splicing is the development of a new creature or its modification.that of an active organism. Treatment of a disease or disorder is the intended outcome of gene therapy. Both procedures also entail the manipulation of genetic material using specialised methods, such as recombinant DNA technology. Finally, for both methods to be effective, a good understanding of genetics is necessary.

Answer:

One of the central conclusions Mendel reached after studying and breeding multiple generations of pea plants was the idea that "[you cannot] draw from the external resemblances [any] conclusions as to [the plants'] internal nature." Today, scientists use the word "phenotype" to refer to what Mendel termed an organism's "external resemblance," and the word "genotype" to refer to what Mendel termed an organism's "internal nature." Thus, to restate Mendel's conclusion in modern terms, an organism's genotype cannot be inferred by simply observing its phenotype. Indeed, Mendel's experiments revealed that phenotypes could be hidden in one generation, only to reemerge in subsequent generations. Mendel thus wondered how organisms preserved the "elementen" (or hereditary material) associated with these traits in the intervening generation, when the traits were hidden from view.

It is important to use an organism with a recessive phenotype in a cross with an organism of an unknown genotype to identify the recessive traits.

The observable traits of an individual are the result of gene expression; the clinical manifestation of a person with a certain genotype is called the phenotype of an individual. Some examples of the phenotype are height, skin color, eye color, hair nature, etc.

The term "genotype" refers to an organism's whole gene pool, or, in other words, the genetic makeup of that creature. The phrase can also be used to describe the alleles, or different forms of a gene, that an organism carries in a more specific meaning.

A recessive phenotype is used in a cross with an organism of unknown Genotype to identify the recessive traits.

The correct answer is - The growth and tissue repair are the major purpose of mitotic cells in multicellular organisms.

Explanation:

The purpose of mitotic cell division in multicellular organisms can be understood by the three points:

1. somatic cells divide through mitotic cell division.

2. Every multicellular organism shows growth and develop with time in size

3. Every cell of the body is repaired with the help of the mitosis that replaces the damaged cell with the new cell.

Single-celled eukaryotes show asexual reproduction by binary fission which is a form of mitosis.

I think all the mice had brown fur due to epistasis

Explanation:

The expected results would be 50% black and 50% brown and the ratio could be 2:2.  But, if epistasis occurred and the brown fur gene overshadowed the black fur gene, then all the offspring could have brown fur.  

The Punnett square to find the expected ratio of black to brown mice pups is to be considered when all the mice had brown fur because to epistasis.

The expected result should be 50% black and 50% brown and the ratio should be considered as the 2:2.

In the case when epistasis should be arisen and brown fur gene should be overshadowed the black.

Hence, the same should be considered.

Answer:

The experiment that scientists could use that would best determine if the tiny structures are spores is called Opto-Electronic Imaging and Imaging Processing.

Explanation:

Optoelectronics speaks to the body of knowledge and of electronic devices that source, detect and control light and how they are used or applied. It is founded on the quantum mechanical effects of light on electronic materials.

Besides Optoelectronic Imaging, there are several other techniques that can be used to identify spores. Some of them are:

1. The culture-based methods: These methods involve the growing of spores on an agar plate and on the enumeration of colony units formed therein.  

2. Culture-independent methods: These methods are based on

the counting of spores under an electron microscope. This method utilizes the hybridization of DNA for the detection of pores. Opto-electric imaging is preferred and considered more efficient because it is faster than all the above processes that have been mentioned. The above processes have the disadvantage of time-consumption.

Lactic acid is created when pyruvate is reduced to make it, while NAD+ is created when NADH is oxidized. Reducing pyruvate to lactate requires a proton from NADH and electrons from the molecule. Thus, option D is correct.

Anaerobic respiration occurs when human muscle cells do not receive enough oxygen. So, the fermentation of lactic acid results in the production of energy molecules. The result of this process is lactic acid.

Oxidize electron transporters to allow for glycolysis re-use. Without the aid of oxygen, fermentation enables cells to generate chemical energy from the breakdown of sugar, such as glucose.

Therefore, in lactic acid fermentation, NAD+ is regenerated for use in glycolysis.
