Prokaryotic cells are the primitive type of cells that lacks organelles and a true nucleus. The plasmid of the prokaryotic cell confers the antibiotic resistance ability to the bacteria.

Plasmids are defined as the extrachromosomal genetic material present along the nucleoid of the prokaryotic cell. They are small circular structures that are present in the cytoplasm of protozoans and bacteria.

They are the double-stranded DNA molecules that are constituted of the genes that confer antibiotic resistance ability to the prokaryote and are helpful in the survival of the prokaryotes. It also protects them from enzyme degradation.

Therefore, plasmids are the extra genetic material that confers antibiotic resistance to the prokaryotic cells.

The right answer is A) Trisomy

Aberrant karyotypes containing an abnormal number of chromosomes are known in the human species. The best-known (and most common) chromosomal abnormality is trisomy 21, which is responsible for Down syndrome (mongolism). There are others such as Turner syndrome (woman with a single X chromosome) or Klinefelter syndrome (man XXY).

These abnormalities originate from the non-disjunction of the chromosomes of a pair of homologues during metaphase I of meiosis. At the end of division I, a daughter cell contains the two chromosomes of the pair considered and the other cell does not contain a chromosome of this pair. A similar result can be obtained during a bad distribution of chromatids during anaphase II.

After fertilization from a gamete of this type, a trisomy or a monosomy is obtained.

Answer:

A: Trisomy

Explanation:

Trisomy The result of fertilization of sperm C with a normal egg containing the haploid chromosome number would be trisomy. We do not know what chromosome underwent nondisjunction, so we cannot be more specific.

Cohesion and adhesion of water: Water can stick to itself (cohesion) and other molecules (adhesion). Specific heat, heat of vaporization, and density of water: Water has a high heat capacity and heat of vaporization, and ice—solid water—is less dense than liquid water.

Is there any answers they give you to choose from?

The answer is the number 2. Why? Because the cytoplasm is a fluid that sustains the cell shape. The mitochondria is a organelle, ribosomes are protiens and vacuoles are carriers/storage bins.

The size of the population will increase.

According to the situation, If 100 is the birth rate and 10 is the death rate. immigration and emigration rate are both 5.Then the population will increase by 90 individual every year. It means if the population is 400 this year, next year it will be 490.

Answer:

Carbohydrates.

Explanation:

Biomolecules may be defined as the important chemical molecules that are present in the living organism. Four important bio molecules are carbohydrates, proteins, lipids and nucleic acids.

The carbohydrates contains the carbon, hydrogen and oxygen in its basic structure. The sugars are the monomers of the carbohydrates. The carbohydrate structure consists of carbon, hydrogen and oxygen in a 1:2:1 ratio.

Thus, the correct answer is option (A).

Answer: The plasma membrane

Explanation:

The plasma membrane also known as the cell membrane, is a covering that surrounds and delimits the cell, separating it from the external environment. It functions as a barrier between the inside of the cell and its environment by allowing molecules to enter and exit through it. This passage of molecules is a phenomenon called permeability. But the membrane does not let all the molecules pass easily, so it is selectively permeable.   The cell membrane is characterized by a dynamic structure, with fluidity being one of its most important features.  This fluidity is temperature-dependent, as it increases with increasing temperature. It also depends on the nature of the lipids that it possesses, since the presence of unsaturated and short-chain lipids favors the increase of fluidity. The presence of cholesterol hardens the membranes, reducing their fluidity and permeability.  Other functions of the cell are related to transport, communication, recognition and cell adhesion.  

In the composition of the membrane 40% corresponds to lipids, 50% to proteins, and 10% to carbohydrates.

The lipids that form the plasma membrane are mainly phospholipids. They form a double layer in which their hydrophilic heads are exposed and their hydrophobic tails are hidden. In each layer of the lipid bilayer the lipids are in continuous lateral movement, giving the membrane its fluid quality.  Membrane proteins are embedded in the lipid bilayer and their proportion varies from cell to cell.  Those on the outer surface or inside the lipid bilayer are peripheral proteins.  Those that penetrate the bilayer are integral proteins.  While the lipid bilayer determines the basic structure of the membrane, the proteins can perform multiple functions such as:

In order to live and grow, cells need to constantly receive nutrients and eliminate waste substances before they accumulate in the cell and cause damage. The cells also secrete substances produced by themselves. All nutrients, waste and secretions must pass through the membrane.  There are three general ways in which substances pass through the plasma membrane:

The cell membrane, also known as the plasma membrane is a thin, flexible barrier that surrounds every living cell, delimiting the cell from the environment around it.

The cell membrane is made of two layers of phospholipids, which are amphipathic molecules with a hydrophilic head and a hydrophobic tail. The hydrophilic heads face the aqueous environment inside and outside the cell, while the hydrophobic tails are sandwiched in between.

This structure allows the cell membrane to be selectively permeable, meaning that it only allows certain molecules to pass through.

The cell membrane is a vital part of every living cell. It plays a role in a wide range of cellular functions, and it is essential for the survival of cells.

Final answer:

The Earth's core is primarily made up of iron and nickel, with a solid inner core surrounded by a liquid outer core that generates the Earth's magnetic field.

Explanation:

The Earth's core is composed primarily of dense metals, predominately iron and nickel. The core can be subdivided into two parts: the outer core, which is in a liquid state and is responsible for Earth's magnetic field, and the inner core, which is solid due to the immense pressure it is under. The core also contains some amount of sulfur. The materials in the core are at a very high density due to the pressure of the overlying layers. The Earth's core begins at a depth of about 2,900 kilometers and has a diameter larger than the planet Mercury.

The process provides immunity against antigens and pathogens in the body fluids is called humoral immunity .

Hence, option C is correct .

Humoral immunity is mediated by the complement proteins, antimicrobial peptides and antibodies etc. It is called humoral immunity because it is found in body fluids and humors.

The humoral immunity provides immunity against the antigens and pathogens that are circulating in the body fluids, such as the lymph and blood. The humoral immunity involves the B-cells and helper T cells. It is also known as the antibody-meditated response. The B-cells recognize the pathogens. When the B cells are activated with the help of the helper T cells, they proliferate and produce plasma cells containing the antibodies.

Hence, the answer is 'Option C - humoral immunity'.

They do most of the work in cells and are required for the structure, function, and regulation of the body's tissues and organs. For example, enzymes are proteins that speed up chemical reactions in the body and hormones, like insulin, are proteins that regulate the activity of cells or organs. Some proteins transport materials throughout your body, such as hemoglobin, which is the oxygen-transporting protein found in your red blood cells.

Answer:

A. the cells will have 2n chromosomes and be diploid.

Explanation:

Mitosis is a type of cell division in which a cell divides into two identical daughter cells. If mother cell is diploid (2n) the daughter cells will be identical having the same diploid (2n) chromosomes. It begins with the division of the nucleus (karyokinesis) followed by division of cytoplasm (cytokinesis). It is an equational division, occurs when organisms require to produce a large number of identical cells.

Tropical rainforests, savannahs, and deserts are categorized under Type A: Tropical or Equatorial Climates, and Type B: Dry or Arid Climates. Rainforests have high rainfall and constant warm temperatures, savannahs can have a wet and dry season, and deserts have very low rainfall with extreme temperature fluctuations.

The tropical rainforest, savannah, and desert biomes are all classified under particular climate types according to the Koppen climate classification system. Each biome is distinguished by specific temperatures and precipitation levels that define its climate category.

Tropical rainforests fall under Type A: Tropical or Equatorial Climates, characterized by warm temperatures year-round and a high level of precipitation, without any pronounced dry season.

Savannahs, or tropical and sub-tropical grasslands, are often associated with Type A climates as well, though some may experience a dry season, placing them in subcategories of this climate type.

Deserts are classified as Type B: Dry or Arid Climates, where there is very low and unpredictable precipitation and temperature can range from very hot to very cold across different times of the day or seasons.

Final answer:

Tropical rainforests are in Type A: Tropical or Equatorial Climates due to abundant rainfall, savannas are a type of tropical grassland in the same climate category, and deserts are classified as Type B: Dry or Arid Climates, characterized by low precipitation and high temperatures.

Explanation:

Tropical rainforests, savannas, and deserts are biomes that are all classified under different types of climates based on their temperature ranges and amounts of precipitation. Tropical rainforests are found in equatorial regions and are known for high levels of precipitation and biodiversity, falling under the Type A: Tropical or Equatorial Climates. Savannas are a form of tropical grassland with a distinct dry and wet season, also falling under Type A climates. Deserts, which could be either hot or cold, are categorized as Type B: Dry or Arid Climates due to their very low and unpredictable precipitation and high temperatures during the day.

The function of the protein is determined by the sequence of the amino acid. The function of protein is determined by its shape, and the shape of the protein is determined by the sequence of nucleotide which is present in the gene which encodes for the protein.

These sequence determine the primary, secondary and tertiary structure of protein which depends mainly on the folding of the protein. And the biological function of the protein such as enzymatic, signalling and structural is determined by these structure.

Example: Each enzyme has a active site where substrate binds in order to carry out reactions. The shape of amino acid depends on the sequence of amino acid and protein folding.

Thus, the structure of amino acid sequence is dependent on the its function.

The structure of an amino acid is directly related to its function in cellular processes.

The structure of an amino acid is directly related to its function in cellular processes. Amino acids, which are the building blocks of proteins, have a central carbon atom bonded to an amino group, a carboxyl group, a hydrogen atom, and an R group or side chain. The R group is what gives each amino acid its unique properties and determines its function in cellular processes.
