If a scientist is attempting to provide support for the hypothesis that RNA was the first genetic material, then RNA can be observed to self-replicate without the assistance of proteins, while DNA always requires protein-based enzymes to replicate would be a workable alternate hypothesis (Option B).

The functions of RNA are not limited to transporting the genetic material from DNA to protein but also act as catalytic agents in some situations, which are called ribozymes, in addition to the reservoir of genetic information for viruses.

Therefore, with this data, we can see that the functions of RNA are not limited to transport genetic information.

Answer:

See the answer below

Explanation:

An increase in the number of exons in a sequence of DNA would result in another protein with a longer amino acid sequence.

Exons are the coding part of a gene as opposed to introns. After transcription, the non-coding part of the gene - the introns - are removed by splicing and the exons are joined back together. The final RNA that will undergo translation consists of only exons.

The longer the exons in a gene, the more the codons present in the corresponding mRNA from the gene, and the more the number of amino acids that would be translated from the mRNA. A longer amino acid chain would result in a different protein.

Hence, a mutation that causes an increase in the number of exons in a sequence of DNA would result in a different protein with a longer amino acid sequence.

Answer:

- Binomial nomenclature is a widely accepted naming system, which is used in the naming of living things. Multiple native names make it extraordinarily tough to establish an organism globally and maintain an observation of the variety of species. Thus, it creates quite a lot of confusion. To eliminate this confusion, a normal protocol came up. According to it, every organism would have one scientific title which might be utilized by everybody to establish an organism.

What is binomial nomenclature?

Binomial Nomenclature follows a universally accepted naming system, which is used to provide a scientific name to a known organism.

Binomial Nomenclature also known as the binary nomenclature.

It uses two-terms during the nomenclature of a specie (plants, animals, and living organisms) that is why it called two-term naming system.

The scientific name of an organism or binomial nomenclature consists of two words, such as the generic epithet and describes the genus and the specific epithet and refers to the species of the organism.

Both of this term is written in italic and the genus name is capitalized.

Binomial nomenclature was given by Swedish botanist and physician Carl Linnaeus. He also called the founder of modern taxonomy.

Carl Linnaeus described and classified thousands of species of plants and animals in his book Systema Naturae.In this technique, there are particular guidelines that are followed while naming organisms. This normal algorithm is relevant to plants and animals whereas giving them distinctive names inside a given system.There are two worldwide codes such as the International Code of Botanical Nomenclature (ICBN) deal with the biological nomenclature for plants and the International Code of Zoological Nomenclature (ICZN) deal with the biological nomenclature of animals.

These two codes agreed upon by all of the biologists over the world for the naming protocol. These codes ensure that every organism will get a selected identity and that identity is globally recognized.

Summary of the limitation binomial nominclature:

- Some of the main drawbacks of binomial nomenclature are: If two or more names are actually in use in compliance with the priority rule, the appropriate name will be used first and the other names will end up being synonyms because authenticity is synonymous with the senior.

Meiosis  (listen); from Ancient Greek'lessening', since it is a reductional division) is a special type of cell division of germ cells in reproducing organisms that produce the gametes, such as sperm or egg cells. It involves two rounds of division that ultimately result in four cells with only one copy of each chromosome (haploid). Additionally, before the division, genetic material from the paternal and maternal copies of each chromosome is crossed over, creating new combinations of code on each chromosome. Later on, during fertilization, the haploid cells produced by meiosis between a male and female will fuse to create a cell with two copies of each chromosome again, the zygote.

Errors in meiosis resulting in aneuploidy (an abnormal number of chromosomes) are the leading known cause of miscarriage and the most frequent genetic cause of developmental disabilities.

Explanation:

The two methods that allow fish to maintain water balance in saltwater are pumping out salt through the gills and absorbing water into the body by osmosis.

In saltwater, the concentration of dissolved salts is higher in the surrounding water than in the fish's body cells. To maintain water balance, fish have developed two main methods:

1. Pumping out salt through the gills: Fish possess specialized cells in their gills that actively pump out excess salts from their bodies. This process helps maintain a lower salt concentration within the fish's body, preventing dehydration and maintaining water balance.

2. Absorbing water into the body by osmosis: Osmosis is the movement of water from an area of lower solute concentration to an area of higher solute concentration through a semi-permeable membrane. Fish have a protective layer of skin that allows water to be absorbed into their bodies while preventing the entry of excessive salts.

By absorbing water through their skin, fish replenish the water lost to the surrounding saltwater, helping to maintain their internal water balance.

These two mechanisms work together to enable fish to survive in saltwater environments. By actively pumping out salts and absorbing water, fish can regulate their internal salt concentration and prevent dehydration, ensuring their overall water balance is maintained.

Answer:

Chromatid Y is called Y because it is one of the two chromatids that make up the Y chromosome. The Y chromosome is one of the two sex chromosomes in humans and other mammals, and is present in males. It is called Y because it was named after the last letter of the alphabet (the "Y" chromosome) to distinguish it from the other sex chromosome, the X chromosome.

The Y chromosome is much smaller than the X chromosome and carries relatively few genes. However, it plays a crucial role in determining an individual's sex. In males, the Y chromosome is responsible for the development of male characteristics such as the presence of testes and the production of sperm.

Each chromosome is made up of two chromatids that are joined together at a centromere. When a cell is preparing to divide, the chromosomes are replicated and each chromosome is made up of two identical chromatids. During cell division, the chromatids are separated and go to different daughter cells.
