The total number of amino acids in the body that can be used in the production of proteins is 20.

Amino acids are the organic compounds that serve as the building blocks of proteins. They are composed of an amino group (-NH2), a carboxyl group (-COOH), and a side chain group (-R), all attached to a central carbon atom.

There are 20 different types of amino acids that are used to produce proteins in the human body. These amino acids can be divided into two groups: essential amino acids and non-essential amino acids.

Essential amino acids cannot be produced by the body and must be obtained through the diet, while non-essential amino acids can be synthesized by the body from other amino acids or molecules.

Explanation:

Acid rain harms numerous animals and plants. Thus, the food web suffers. Acid rain kills lake phytoplankton. As a result, phytoplankton-dependent insects die. Therefore, option (C) is correct.

Acid rain, also known as acid deposition, is an all-encompassing word that refers to any form of precipitation that contains acidic components, such as sulfuric or nitric acid, and that falls to the ground from the atmosphere in either a wet or dry form. Acid precipitation can take several forms, such as rain, snow, fog, hail, or even dust.

Rain that contains acid can provide significant challenges for a wide variety of flora and fauna. As a direct consequence of this, the entire food web is disrupted. For instance, phytoplankton in lakes might perish as a direct result of acid rain. As a result of there being less phytoplankton available, the insects, which get their nutrition from it, are starting to starve to death.

Therefore, option (C) is correct.

Tumor suppressors or Oncogenes  are the genes that  prevent the cell cycle from going out of control.

When cells grow and divide abnormally and continuously an abnormal mass of tissue is formed which is called as a tumor. Tumors may or may not be cancer, that is they can be malignant or benign. Benign tumors grow but does not spread or invade to adjacent tissues, in contrast malignant tumors can spread to nearby tissues.

To prevent formation of these abnormal cell masses, tumor suppressors are genes that prevent cell cycles from going out of control. These tumor suppressors prevent formation of tumors.

Organic molecules produced from spontaneous synthesis or from meteorites

Explanation:

The evidence that none of the spider offspring have a new gene version refutes the claim that spiders can acquire new genetic material from their prey. This is because the absence of new gene versions in the offspring indicates that the genetic material from the prey is not incorporated into the spider's DNA. If spiders were able to acquire new genetic material from their prey, then it would be expected that at least some of the offspring would have a new gene version not found in either parent. Therefore, this evidence suggests that the claim that spiders can acquire new genetic material from their prey is not supported.

Answer: Biomagnification refers to the process by which the concentration of a contaminant increases as you move to higher trophic levels in a food chain or food web. In other words, as organisms consume other organisms, the contaminants present in the prey accumulate and become more concentrated in the bodies of the predators.

To understand this process, let's consider an example involving a water ecosystem. Suppose a pollutant is released into the water, such as a pesticide or heavy metal. The primary producers, such as algae or aquatic plants, absorb small amounts of the contaminant from the water. As herbivorous organisms consume these primary producers, they ingest the contaminants along with their food.

Since the contaminant is not easily broken down or eliminated from the organisms' bodies, it accumulates over time. As a result, the concentration of the contaminant becomes higher in the herbivores than in the primary producers. Now, when carnivorous organisms consume the herbivores, they not only accumulate the contaminant from their own food but also from all the prey they have consumed. This leads to an even higher concentration of the contaminant in the carnivores.

Therefore, biomagnification describes the phenomenon where the concentration of a contaminant increases significantly as you move up the food chain or trophic levels. The highest concentration of contaminants is often found in top predators, such as large fish, birds of prey, or mammals, which can have adverse effects on their health and reproductive capabilities.

It's important to note that biomagnification primarily occurs for persistent and non-biodegradable contaminants that cannot be easily metabolized or excreted by organisms. These contaminants are often lipophilic (fat-soluble), which allows them to accumulate in fatty tissues and remain in the organism's body for long periods, leading to biomagnification.

Answer:

The correct answer is B. "Melanocytes and muscle cells express different genes."

Although all cells in an organism (such as a human) contain the same DNA, different cell types express different sets of genes. Gene expression is the process by which specific genes are activated to produce a needed protein. In this case, the gene responsible for melanin production is expressed in melanocytes, but not in muscle cells.

This does not mean that muscle cells have destroyed the gene for melanin (as stated in option C) or that melanocytes contain different genes from muscle cells (as stated in option D). All cells within an organism contain the same genes, but not all genes are expressed in every cell. The process of gene expression is regulated by the cell to ensure that each cell type functions properly.

Option A is also incorrect because all cells, including both muscle cells and melanocytes, rely on both DNA (for storing genetic information) and RNA (for transmitting that information and producing proteins). DNA is transcribed into RNA, which is then translated into proteins. This process occurs in all cells.

The statement explains the difference between skin melanocytes and muscle cells is - melanocytes and muscle cells express different genes. So option b  is correct.

Melanocytes are dark, dendritic-shaped, highly differentiated cells that secrete melanin, a pigment found in melanosomes, which is the primary function of melanocytes.

Melanocytes are a type of cell derived from the neural crest. They form a synapse with keratinocytes through their dendrites in the epidermis. Melanocytes play an important part in skin pigmentation and their role in the generation and distribution of melanin has been extensively studied.

The correct order for transcription is as follows:
1. A small portion of the DNA double helix unwinds .
2. The mRNA nucleotides enter the nucleus through the nuclear pores.
3. The mRNA locates the correct DNA sequence and pair up together.
4. The mRNA, with the "blueprint" for making a specific protein, leaves the nucleus .

To start the process of protein synthesis, the DNA sequence needs to be transcribed into mRNA. This is the process of transcription.
Transcription is the process of synthesizing an RNA copy of a segment of DNA. This RNA copy is called messenger RNA or mRNA, and it carries the genetic information from DNA to the ribosome, where it will be used to make a protein. Transcription is a critical step in protein synthesis because it is responsible for creating the messenger RNA that will ultimately be translated into the amino acid sequence of the protein. Overall, transcription is a complex process that involves many steps, but it is a crucial part of the synthesis of proteins in the cell.

Answer:

It means "True bactria" --> A.

Answer:

A. True bacteria

Explanation:

Eubacteria means "True bacteria".

Explanation:

A buffer is an aqueous solution that can resist significant changes in pH levels upon the addition of small amount of acid or alkali. Each buffer is characterized by a set ‘capacity’ which is defined as the quantity of strong acid or base that must be added to change the pH of one liter of solution by one pH unit. In other words, buffer capacity is the amount of acid or base that can be added before the pH begins to change significantly.

A buffer range is the specific pH range in which a buffer effectively neutralizes the added acid or base, while maintaining nearly constant pH. Capacity and range of a particular buffer ensures that the added small amount of acid/base is neutralized and the chemical reaction keeps going without giving a wrong outcome for the experiment/process. Simply put, a buffer is a mixture of a weak acid and its conjugate base or a weak base and its conjugate acid
