Ethics in general means the moral principles of an individual which rules the mind of an individual and tells him/her about the good or bad.

Ethics play a very important role in science, like there should not be any biased research and also there should be honest reporting of data. If the data is copied or used from any other research done by other scientist then one must provide the credit of sourcing of information. There are many chemicals which are made by the researchers which are very useful for the mankind but on the same hand those can be also used as a weapon and used for mass destruction of mankind, so it is all upto the moral or ethics of the individual.

Answer:

The water vapor content in the atmosphere is typically recorded using a measurement called relative humidity, which represents the amount of water vapor present in the air relative to the maximum amount the air could hold at a given temperature. Therefore, if two locations have different water vapor content in the atmosphere, it is likely that they would have different relative humidity readings.

For example, if one location has a higher water vapor content in the air, it would have a higher relative humidity measurement than a location with a lower water vapor content. Conversely, if one location has a lower water vapor content in the air, it would have a lower relative humidity measurement than a location with a higher water vapor content.

It is important to note that other factors can also influence relative humidity measurements, such as temperature and atmospheric pressure, so a direct comparison of relative humidity readings between two locations should take these factors into account.

Diffusion is an essential process for the functioning of cells, as it allows for the exchange of materials and energy between the cell and its environment. Diffusion occurs when molecules move from an area of higher concentration to an area of lower concentration. This process occurs within the cell membrane, as molecules of solutes move across the membrane as well as through the membrane. Diffusion is important for the transport of substances across cells, which is necessary for metabolic processes and other essential functions. Diffusion is an important process that helps cells to maintain homeostasis.

It is evident that the dominant characteristic, which is present on the autosome and causes disease, does not exist on the sex chromosomes. Here, autosomal dominance is the mode of inheritance. Therefore, No is the appropriate response.

Pedigree, which determines how traits are passed down from one generation to the next, is similar to a family tree. With pedigree: 1) A square box is used to symbolise men. 2) A circle is used to represent women. 3) Straight horizontal line signifies Mating whereas a vertical line represents that both individuals have offspring. 4) Shaded areas show affected people, whereas un-shaded areas show healthy people.

This indicates that the parents are heterozygous for the trait because only one offspring is affected and the other is unaffected. It is autosomal dominant in terms of inheritance.

Answer:

Advantages of using ethanol as fuel

A. It is a carbon-neutral activity

C. It does not produce toxic gases when burnt

D. It can be mixed with conventional petrol to make gasohol

Disadvantages

B. It takes a lot of plant materials to produce the ethanol

Explanation:

It has been proven that blending ethanol with conventional petrol produces gasohol and this helps to reduce the harmful emissions of CO, hydrocarbons, etc. This then means that vehicles that run on ethanol produces fewer harmful emissions than those that run on gasoline. For ethanol, it produces a no net carbon dioxide emissions.

Ethanol is considered to be atmospheric carbon neutral when the combustion of ethanol is made from biomass (such as sugarcane and corn). Ethanol is made plant materials like grains and crops that possess high starch. Also, it can be made from sugar content such as sugar cane, sorghum, corn, barley and sugar beets.

The particles of the substance initially had high Kinetic Energy.​

Gas particles move quickly in all directions and regularly collide with one another and the container's side. The particles gather kinetic energy and accelerate as the temperature rises. The particles' real average speed is influenced by their mass and temperature.

In liquids, particles are quite close together and move with random motion throughout the container. Due to the closer proximity of the particles, collisions between them happen more frequently than in gases even if particles are moving quickly in all directions.

Sexual reproduction in plants involves the fusion of male and female gametes to produce offspring with genetic diversity.

Mechanisms that facilitate sexual reproduction in plants are examples:

1)Pollination and Fertilization: Many plants rely on pollinators, such as bees, butterflies, or birds, to transfer pollen from the male reproductive structures (anthers) to the female reproductive structures (stigma) of flowers.

This process enables the fusion of sperm cells within the pollen with egg cells in the ovules, leading to fertilization.

Examples include flowering plants like roses, sunflowers, and apple trees.

2)Seed Production: After fertilization, the ovule develops into a seed. Seeds contain an embryo, formed by the fertilized egg, enclosed within a protective seed coat.

The mature seeds can disperse and germinate to give rise to new plants.

Various plant groups, including angiosperms (flowering plants) and gymnosperms (conifers and cycads), reproduce sexually through seed production.

3)Alternation of Generations: In plants with a complex life cycle, such as ferns, mosses, and liverworts, sexual reproduction involves an alternation between two distinct generations: the gametophyte and the sporophyte.

The gametophyte generation produces gametes (sperm and eggs) through specialized structures, while the fusion of gametes gives rise to the sporophyte generation, which produces spores.

4)Self-fertilization: Some plants have the ability to self-fertilize, where the pollen from the anther of a flower is transferred to the stigma of the same flower or another flower on the same plant.

This allows for sexual reproduction without the need for external pollinators. Self-fertilization can be seen in plants like tomatoes, peas, and certain grass species.

Explanation:

The vertebrate forelimb of human, bird, and bat may not appear to have much in common, but a closer examination of the anatomy shows that the same bones were applied to a variety of different jobs in each of these species. Evolution doesn't plan ahead. It can only work with what's available. The color coding shows the way the bony elements were modified in each species. You might think that the two wings would be more similar in design because of the job they do but, in fact, the bird wing and human arm are more similar on the interior. However, the bird "hand" is reduced, whereas the bat and human hand have more in common. See if you can find a similar image of a dolphin or whale flipper for another comparison.

Natural selection is a mechanism of evolution. Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success. This process causes species to change and diverge over time.

Homologous structures are structures that are similar in related organisms because they were inherited from a common ancestor. These structures may or may not have the same function in the descendants. Figure \(\PageIndex{3}\) shows the upper appendages of several different mammals. They all have the same basic pattern of bones, although they now have different functions. All of these mammals inherited this basic bone pattern from a common ancestor.

The anole lizard is a tree-dwelling reptile that has adapted to live almost anywhere. Because the rain forest is rich with species of anole, many lizards are competing for the same food and the same living space. Oftentimes, anoles will avoid competition by occupying different portions of the rain forest. For example, one species of anole may live in the canopy, while another species live near the forest floor. This behaviour is an example of- niche partitioning.

What is niche partitioning?

The process by which competing species use the environment differently to enable them coexist is known as niche partitioning in ecology. According to the competitive exclusion principle, two species with identical niches (ecological roles) will always drive the other one to extinction if they compete.
