The monosaccharides is formed by just bounding of C, H and O.

Monosaccharides are simplest molecule or unit in the carbohydrates group which united with each other to form di, tri or polysaccharide structure. As these are the simplest unit in carbohydrates, they are only formed by numbers of carbon, oxygen and hydrogen atoms. The number of atoms in the chain of monosaccharides varies with changing required compound. for example in deoxyribose, one of hydrogen is not present in its structure but present in ribose.

The main reason is slope and high altitude of mountains with low water availability.

Mountain slope soil is often infertile due to erosion caused by water runoff, which depletes the nutrient-rich material in soil. Conversely, valleys, particularly those near large rivers, have fertile soil due to regular deposits of nutrients from the flooding and receding of rivers. Human practices like terrace farming can also transform infertile mountain soil into fertile land.

The reason the soil on mountain slopes is typically infertile while the soil in valleys can be fertile has to do with topography, water runoff, and nutrient deposition seasonality. Steep slopes are prone to erosion, so the soil becomes thin and less nutrient-rich as parent material is washed away. This means less optimal conditions for plants, which further results in soil infertility.

Conversely, valleys, especially those near large rivers, receive frequent deposits of organic matter during flooding. This seasonal activity replenishes the soil with nutrients, making it fertile. Additionally, human activities like irrigation and plowing, originally practiced by ancient riverine farmers, can further enhance soil fertility in these low-lying areas.

It's also worth mentioning unique practices like terrace farming, used to transform the steep, infertile mountainsides into flatter, arable land. This agricultural innovation made possible by human creativity and resourcefulness has allowed the cultivation of crops in challenging terrains, demonstrating how human adaptability can defy the geographical constraints imposed by topography.

First what is mitosis?

Mitosis is a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth.

According to definition,

Answer:

Option (1), (3), (4) and (5).

Explanation:

Mitosis may be defined as a type of cell division by which the cell multiply their number. The four stages of mitosis are prophase, metaphase, anaphase and telophase.

Two daughter cells are produced from the parent cell by the process of mitosis. The chromosome number remains same in the daughter cells and the  cells are almost identical to the parent cell. Single division is involved in mitosis. Mitosis occurs in the somatic cells of the body and meiosis occurs in the gametic cells. The DNA replication occurs in the synthesis phase and completes before the cell division.

Thus, the correct answer is option (1), (3), (4) and (5).

The first responders are the ones who reaches at the crime scene before anyone else. The first responders are usually the police officers. The duty of the first responders is to provide any aid or assistance to the victims that may be present on the scene. The first responders then secure the crime scene so that the scene is not contaminated.

Hence, the answer is 'Option D - renders aid and assistance'.

The CSI team members arriving on the crime scene after the first responders have left with the victim should immediately secure the crime scene. The securing of the crime scene is necessary so that the evidences present at the scene are not contaminated and can be collected for forensic tests.

Hence, the answer is 'Option A - secure the crime scene'.

The first responder in a crime scene is generally police officers. The prime and important duty of an officer in the crime scene is to look for a victim and provide him/her with proper aid and assistance.

The first action of first responder of the crime scene will be securing the scene.

Further Explanation:

The first responders or the police officers are the people who officially respond to the crime scene at first. The moment an officer reaches a crime scene he/she must look for a victim and determine whether the victim is alive or not. If alive, the office must provide all the required assistance and aid to the victim as his/her prime duty.

The officers at the crime scene are also responsible for protecting the crime scene and public present there. They also control any further changes in the crime scene after occurrence of the incident. The first responders must also take care of their safety as well as the safety of the local citizens. For this reason, they must also look for a suspect at the crime scene.

An atom becomes a positive ion by losing one or more of its electrons. Positively charged ions are called cations.

Positively charged ions are called cations. Generally, metallic elements turn into positive ions due to the quantity of valence electrons they contain. Metallic ions can achieve a full valence shell if they lose their outer electron(s). When they lose these electrons, the inner shell is now their valence shell, and it's complete. When this happens, they will have more protons than electrons, giving the atom a positive charge.

An atom becomes a positive ion (cation) when it loses one or more electrons from its outermost energy level.

Electrons carry a negative charge, so when an atom loses electrons, it has an excess of positive charge compared to its negative charge, resulting in a net positive charge.

An atom can lose electrons through a process called electron transfer, where it interacts with another atom or molecule.

Atoms can also become positive ions by absorbing sufficient energy. This can occur through various means, such as exposure to high temperatures or intense electromagnetic radiation.

Thus, an atom becomes a positive ion known  as cation, when it loses one or more electrons from its outermost energy level.

Final answer:

The statement that mutations always negatively impact a population is false. Mutations can be beneficial, harmful, or neutral, affecting an organism's fitness in different ways. Neutral mutations sometimes play a role in the long-term evolutionary changes of a population.

Explanation:

The statement that mutations always negatively impact a population is false. While it is true that many mutations are harmful, changing a functional allele to a less or nonfunctional one, some mutations have beneficial effects, such as increasing an organism's fitness. Moreover, many neutral mutations have no immediate effect on an organism's fitness but may still play a role in the long-term evolutionary process.

Advantageous mutations can lead to improved survival and chances of reproduction, as seen with the mutation that conferred insecticide resistance in mosquitos or the black coloration in peppered moths during the Industrial Revolution. Harmful mutations, on the other hand, can decrease an organism's fitness by reducing its likelihood of survival or the number of offspring it can produce. However, the evolutionary impact of mutations cannot be oversimplified; neutral mutations and those with only a slight effect can, over time, contribute to significant genetic diversity within a population.

The niche of the giraffe is characterized by its unique adaptation of a long neck to feed on high foliage, which reduces competition for food sources. Variation among species, as exemplified by giraffes, is vital for adaptation and survival in changing environments. The giraffe's distinct niche also demonstrates the concept of competitive exclusion in ecological communities.

The niche of the giraffe is highly specialized within its ecosystem. Giraffes have evolved certain structural adaptations, such as their long necks, to exploit a unique resource – the high foliage of trees in their habitat. These majestic animals browse on leaves that are out of reach for most other terrestrial herbivores, reducing direct competition for food. In addition, their height enables them to spot predators from long distances, which is beneficial in the open habitats of the African savannas.

Furthermore, the ecological niche involves not only the giraffe's food sources but also their role within the community. By feeding on higher vegetation, giraffes may also play a part in shaping the structure of their environment, which can affect other species. The niche of a giraffe showcases the importance of variation among species, which can be crucial for survival amid environmental changes.

Lastly, the giraffe's niche reflects the concept of competitive exclusion. No two species can occupy the exact same niche within an ecosystem. Thus, giraffes have carved out a niche that allows them to live without direct competition for their primary food source, ensuring their continued survival unless environmental conditions change drastically enough to challenge their adaptability.

The correct answer is: D.  damage to nerves that control the stomach.

The vagus nerve is a cranial nerve that controls stomach contractions and thus, the movement of the food. When the vagus nerve is damaged, the muscles of the stomach do not function properly, so gastroparesis occur. Consequently,  food then moves slowly or even totally stops moving through the digestive tract.

I believe the answer is D, Cells get energy by taking in nutrients from food. Correct me if I'm wrong.

Final answer:

OPTION D.

Cells acquire energy by converting nutrients from food into ATP, the cell's energy currency. While oxygen is crucial for aerobic respiration, ATP can also be produced without oxygen through processes like glycolysis.

Explanation:

Cells obtain energy to perform their necessary functions through a process called cellular respiration. This process involves converting nutrients from food into adenosine triphosphate (ATP), which cells use as a direct source of energy. Specifically, cells acquire energy from carbohydrates, fats, and proteins that they metabolize. Oxygen plays a crucial role in this process, especially during aerobic respiration, which is the most efficient form of cellular respiration. However, some organisms can also produce ATP in the absence of oxygen through processes like glycolysis.

Through photosynthesis, certain organisms convert solar energy into chemical energy, which is ultimately used to build carbohydrates. These carbohydrates are then consumed by other organisms, and the energy stored within their bonds is released and harnessed for cellular work during cellular respiration.
