Lip print evidence can potentially contribute to proving that an individual committed a crime, or it may be used to exonerate someone, but it cannot conclusively prove guilt or innocence on its own. It's a type of forensic evidence that, like fingerprints, can be unique to an individual and may place a person at a crime scene.

Forensic evidence, such as lip prints, is often part of the puzzle that investigators piece together when solving a crime. Lip prints, known as cheiloscopy, are the pattern of lines on the lips that are unique to each person. Just as fingerprints can be used to identify individuals, lip prints can also serve as a means of identification. However, the presence of someone's lip prints at a crime scene does not, by itself, prove that the person committed the crime. It can suggest that the individual was present, but additional evidence is generally needed to establish guilt beyond a reasonable doubt. Similarly, if an individual's lip prints are not found at a crime scene, this might help to exonerate them, but it is not definitive proof of innocence either, as the perpetrator might not have left any lip prints, or they could have been removed or obscured. The use of lip print evidence in court depends on the expert testimony that establishes the relevance and reliability of the method used to obtain and interpret the lip prints.

Answer: A. Loss of biodiversity

Endangered species are those animal or plant species which are at risk of being extinct. The number or population of such species decreases either rapidly or suddenly due to loss of habitat, migration, hunting, poaching, climate change and because of other reasons.

The loss of endangered species from the native habitat can directly reduce the available biodiversity.

Answer:

Loss of biodiversity

Explanation:

Answer:

Isotopes such as fluorine-18, gallium-67, krypton-81m, rubidium-82, nitrogen-13, technetium-99m, indium-111, iodine-123.

Explanation:

For diagnostics, medical imaging radiopharmaceuticals are used intravenously or orally. After which external detectors catch the images from the radiation that is emitted from these isotopes also used in MRI and CT scanners.

Iodine 123 is used for examining the whole body part. In developed countries about 26 % of the population use 2%/ year of these medications for the therapies, and these nuclear medicines were developed in the 1950s by physicians who emphasized there use of Iodine 131 for the treatment of thyroid disease.

These isotopes consist of molybdenum-99, which has half-life 66 hours,

Plants reproduce sexually through their flowers. The flowers have both the male and the female organs. Pollens contain the male gametes and the stimage is a long tube connecting to the female organ of ovary that has the female gametes. The pollen grains need to stick to the stigma for the pollination to begin. This can happen in two ways:

a. Self-pollination: When the pollens of the same plant or flower end up on its stigma. This can happen by the force of wind.

b. Cross-pollination: When the pollens of one plant end up on the stigma of the other plant's flower. This happens when insects while visiting a flower get pollen grains stuck on their body and deposit it at the stigma of the other plant's flower when they sit on it.

The best example would be of the Hibiscus and the Yucca plant flower, each of which gets pollinated by insects.

The human immunodeficiency virus (HIV) that causes the disease known as aids selectively infects helper T cells (CD4+).

This retrovirus also infects macrophages and dendritic cells. When CD4+ T cell numbers decrease below a critical level (due to the killing of this cells with different mechanisms), cell-mediated immunity is lost. As a result, the body becomes progressively more susceptible to infections, leading to the development of AIDS.

 HIV can be transmitted only via body fluids like blood, semen, pre-seminal fluid, rectal fluids, vaginal fluids, and breast milk, which means that people usually get or transmit HIV through sexual behaviours and use of the needle. For HIV infection, these fluids must come in direct contact with a mucous membrane or damaged tissue. Another way is to be directly injected into the bloodstream (from a needle for example).

Answer: Congeneration is a process of producing electricity and heat simultaneously.

Explanation:

The rationality of congeneration lies essentially in the saving of energy resources in the face of a conventional configuration that produces the same amounts of useful heat and work, which is usually converted to electrical or mechanical energy.

Congeneration is a very efficient energy production process, providing several benefits. At a local level, it can significantly reduce the user's energy bill, while at a global level it reduces the consumption of fossil fuel reserves, leading to a significant reduction in the environmental impact of using these fuels.

Final answer:

Objective vision is the ability to identify specific objects through sight, which is enabled by the complex interaction between the eyes and the brain.

Explanation:

“Objective vision” is the type of vision that identifies specific objects. Vision is crucial for many aspects of life and is the ability to detect light and see. The eye and the brain play essential roles in this sensory experience, allowing us to see in color, and three dimensions, and focus on various distances. Vision issues like myopia and hyperopia can be corrected with optical lenses or surgery. Animals and humans have evolved complex visual systems that prioritize vital visual information, making vision one of the most important senses. Around one-third of the human cerebral cortex is dedicated to processing visual information, highlighting the significance of vision in our daily lives.

The advantages of different skin colours of the frog is in survival, they help them camouflage from predators. If a predator is below them, the brighter ventral site simulates the bright sky (or water surface). If the predator is above, then dorsal side helps the frog to blend into the surrounding ground environment (or floating vegetation). 

Final answer:

Frogs have a dark dorsal side and light ventral side, an adaptation known as countershading, to camouflage from predators. This, along with their specialized eyelids and tympanum, are critical adaptations for survival in their environments.

Explanation:

The dark dorsal side and the light ventral side of a frog is an adaptation known as countershading, which helps provide camouflage from predators. When predators look down on the frog from above, the dark dorsal side blends with the darker environments underwater or on the forest floor. Conversely, when predators or prey look up at the frog against the light sky or water surface, the light ventral side makes it more difficult to see. This adaptive trait is complemented by the frog's skin texture and coloration that aid in blending with their environment.

In addition to their skin adaptations, frogs have three eyelid membranes that protect their eyes and aid their vision in different environments, both on land and underwater. Their tympanum, a part of their hearing apparatus, is well-developed to pick up on sounds, which plays a role in communication and predator avoidance. Frogs are also known to change from having a tail during their tadpole stage to losing it as adults, which is an adaptation to their life stages from water to land.

Researchers initially believed proteins were the genetic material due to their complexity and diversity, but experiments by Chase and Hershey in 1952 confirmed DNA as the genetic material.

Researchers initially thought that protein was the genetic material because of its abundance, diversity, and complex structure. Proteins, with their wide array of 20 different amino acids, appeared to offer the biological specificity necessary to explain an organism's myriad genetic traits. By contrast, DNA seemed too simple, with only four types of nucleotides, to account for the vast complexity of hereditary information. For many decades, the remarkable structural diversity of proteins led scientists to view them as the more plausible candidates for carrying genetic information. In 1952, decisive experiments by Martha Chase and Alfred Hershey provided confirmatory evidence that DNA, not protein, was the genetic material. Their work with bacteriophages marked a turning point in our understanding, proving that DNA, despite its simplicity, carried the code of life.

Experiments conducted by Martha Chase and Alfred Hershey in 1952 provided confirmatory evidence that DNA was the genetic material and not proteins. Chase and Hershey were studying a bacteriophage, which is a virus that infects bacteria. Viruses typically have a simple structure: a protein coat, called the capsid, and a nucleic acid core that contains the genetic material, either DNA or RNA. The bacteriophage infects the host bacterial cell by attaching to its surface, and then it injects its nucleic acids inside the cell. The phage DNA makes multiple copies of itself using the host machinery, and eventually the host cell bursts, releasing a large number of bacteriophages. Hershey and Chase labeled one batch of phage with radioactive sulfur, ³5S, to label the protein coat. Another batch of phage were labeled with radioactive phosphorus, ³2p. Because phosphorous is found in DNA, but not protein, the DNA and not the protein would be tagged with radioactive phosphorus.

Answer:

Memories that are related to specific life experiences, such as recalling the events of a vacation, are called episodic memories.

Explanation:

Human memory is composed of different types of memory. Episodic memory require recollections of a specific event or an episode for remembering events that occurred during a vacation, People associates particular details with an episodic memory, such as how they felt, the time and place, and other particulars. Thanks to this memory we have the ability to recall and mentally re-experience specific episodes from one's personal past, the individual is able to re-experience individual events. For example people can remember who was on vacation, where it occurred, and their own personal interactions.

1. Boron has a smaller radius and the protons in carbon exert a greater pull.

2. H2O

1. Boron and carbon have the same number of electron shells, but boron has one less proton in its nucleus than carbon. This means that boron has a smaller radius than carbon due to a weaker nuclear charge, but carbon has a greater pull exerted by its protons due to a stronger nuclear charge.

2. A compound is a substance that consists of two or more different elements chemically bonded together in a fixed ratio.

Cl2 and H2 are both molecules, but they are not compounds because they consist of only one element (chlorine and hydrogen, respectively).

He is a noble gas and exists as individual atoms, not as a compound.

Answer:

Pancreatic duct delivers chemicals to duodenum of small intestine.

Explanation:

Pancreatic duct is the complex structure, also called the hepatopancreatic duct. It is formed of pancreatic duct itself along with common bile duct, carrying bile juice from liver, and opens into the lesser curvature of duodenum.

The pancreatic duct delivers pancreatic juice, contains a lot of enzymes like amylase, lipase, DNAase, RNAase, carboxypeptidase, aminopeptidase etc and bile juice containing bile salts and cholesterol, with heavy metal ions, and bile pigments etc.
