The given statement is true. The deoxyribonucleic acid (DNA) molecules can be changed or altered and this process is termed mutation.

A mutation in biology is an adjustment to the nucleic acid sequence of an organism's, virus's, or extrachromosomal DNA.  DNA or RNA can be found in the viral genome. Errors in DNA replication, viral replication, mitosis, meiosis, or other types of DNA damage (like pyrimidine dimers from exposure to ultraviolet radiation) can result in mutations.

Damaged DNA may then undergo error-prone repair, particularly microhomology-mediated end joining,cause an error during other types of repair,, or result in a replication error (translesion synthesis). Due to mobile genetic elements, mutations can also be caused through the insertion or deletion of DNA segments.

By manufacturing solutes that are consistent with their metabolism and growth, many microorganisms maintain a little higher solute concentration in their protoplasm, keeping their membrane pushed snugly against the cell wall.

From 5 minutes to 1(1/2) hours after the tissue has been removed from the body, the osmotic pressure maintained by liver or kidney tissue as determined by its water equilibrium with solutions of sodium chloride stays unaltered. At high osmotic pressure, solute accumulation strongly promotes bacterial growth, whereas solute release enables cells to withstand osmotic downshocks.

When meat is devoid of water and salt is added, a solute-rich environment is created that causes osmotic pressure to suck water from bacteria, slowing their growth. To accomplish this, salt content must be close to 20%.

Polar vs n-p covalent bonds affect the charge of the atoms involved.

Molecules that generally have  polar covalent bonds can contain positive and negative charges.

Covalent bonds can be polar or nonpolar, depending on the electronegativity difference between the poles. The covalency between two identical atoms (as in H2) are nonpolar in a molecule the electronegativity of the ions are uniformly spread over. There is no net charge on either atom. Therefore the attractive force is produced,when  the electron pair interacts with the nuclei of both the atoms. While those which are unlike atoms are polar then one atom is slightly negatively charged and the other is slightly positively charged for example hydrochloric acid(HCl).

Answer:

Explanation:

Scientists most often use the morphological and genetic characteristics of organisms to form the basis for biological classification. Morphological characteristics refer to an organism's physical features, such as its size, shape, color, and structure. Genetic characteristics refer to an organism's genetic makeup, including its DNA sequence and other molecular features.

In the past, scientists relied primarily on morphological characteristics to classify organisms. They would group organisms together based on similarities in physical appearance and structure. For example, birds and bats were once classified together based on their ability to fly, despite the fact that birds are warm-blooded and have feathers while bats are mammals with fur and produce milk for their young.

Today, with advances in technology and our understanding of genetics, scientists use a combination of morphological and genetic characteristics to classify organisms. DNA sequencing and other molecular techniques can provide insight into the evolutionary relationships between organisms, and allow for a more accurate classification system. For example, genetic analysis has led to the reclassification of some organisms that were once thought to be closely related based on their physical appearance, but are now known to be more distantly related based on their genetic makeup.

Overall, the goal of biological classification is to create a system that accurately reflects the evolutionary relationships between organisms and helps us better understand the diversity of life on Earth.

Option C. Light is the immediate source of energy for ATP synthesis in chloroplasts and photosynthetic bacteria.

During photosynthesis, light energy is absorbed by pigments, such as chlorophyll, in the thylakoid membranes of chloroplasts or in the plasma membranes of photosynthetic bacteria. This light energy is then used to power a series of electron transport reactions that ultimately generate a proton gradient across the thylakoid membrane or the plasma membrane.

The electrochemical proton gradient (PMF) generated across the membrane serves as a source of energy to synthesize ATP via the enzyme ATP synthase. The energy of the PMF is used to power the rotary motion of the ATP synthase, which catalyzes the synthesis of ATP from ADP and inorganic phosphate.However, it is important to note that NADPH is also an important product of the light reactions in photosynthesis. NADPH, along with ATP, is used as a source of energy to power the carbon-fixing reactions of the Calvin cycle, which produce glucose and other organic molecules from carbon dioxide.

The type of signal that directs the synaptic vesicles to release their neurotransmitters into the synapse is a repeated, intense electrical signal.

This signal causes an influx of calcium ions into the presynaptic neuron's cell membrane, which triggers the synaptic vesicles to release the neurotransmitters into the synapse.

Synaptic vesicles are small, membrane-bound structures that are found in the presynaptic terminal of neurons. They store neurotransmitters, which are chemicals that are released by the neuron in order to communicate with other neurons. When the neuron is stimulated, the synaptic vesicles are triggered to release their neurotransmitters into the synapse, where they can bind to receptors on the postsynaptic neuron, allowing for the transmission of signals between neurons. The release of neurotransmitters from the synaptic vesicles is regulated by a repeated, intense electrical signal, which causes an influx of calcium ions into the presynaptic neuron's cell membrane, which triggers the synaptic vesicles to release their neurotransmitters into the synapse.

Autotrophs are known as producers because they are able to make their own food from raw materials and energy.  Heterotrophs are known as consumers because they consume producers or other consumers.

An organism that can make its own nourishment by the use of light, water, carbon dioxide, or other substances is an autotroph. Autotrophs are also referred to as producers because they make their own nourishment. Photosynthesis is the method that most autotrophs employ to produce their food. During photosynthesis, autotrophs use the sun's energy to transform soil-derived water and atmospheric carbon dioxide into glucose, a nutrition. A kind of sugar is glucose. Plants get their energy from glucose. Furthermore, cellulose, which is used by plants to grow and construct cell walls, is produced by them from glucose.

An organism that consumes other plants or animals for energy and nutrients is referred to as a heterotroph. The word is derived from the Greek terms "nourishment" and "hodos" for "other."

Autotrophs and heterotrophs are two main classifications of organisms depending on how they receive energy and nutrients. Autotrophs are referred to as producers since they can generate their own food using energy and raw resources. Plants, algae, and several varieties of bacteria are examples. Because they eat producers or other consumers, heterotrophs are referred to as consumers. Humans, dogs, and birds are all instances of heterotrophs.
