Animals are divided into two groups; vertebrates and invertebrates. Animal classification is a matter of sorting out similarities and differences. This sorting process enables scientists to describe characteristics through the various levels of animal groups and subgroups. Among the most basic criteria by which animals are sorted is whether or not they possess a backbone. This single trait places an animal into one of two groups: the vertebrates (with backbone) or the invertebrates (without backbone). This represents a fundamental division among all animals.

What internal structure identifies an organism as an invertebrate?

The genotypic ratio of dihybrid cross of round yellow is 9:3:3:1 .

Mendel noticed that his dihybrid cross' F2 offspring had a 9:3:3:1 ratio and produced nine plants with round, yellow seeds, three plants with round, green seeds, three plants with wrinkled, yellow seeds, and one plant with wrinkled, green seeds.

An organism's genotype is made up of all of its genetic components. [1] The term "genotype" can also be used to describe the alleles or genetic variations that a person carries in a certain gene or genetic region. [2] The ploidy, or number of copies of each chromosome, found in that species, determines how many alleles a person can have for a given gene.

Bacteria can be classified on the basis of some of their main features which include their shape, mode of nutrition, mode of respiration and composition of their cell wall.

Bacteria are single-celled organisms which are able to survive in a wide range of conditions are found almost everywhere in the environment. They can be classified on the basis of some of their main features. The first feature is shape. Bacteria in nature can be found in different shapes which include rod-shaped, sphere, spiral etc. Another feature is their mode of nutrition which can be either heterotrophic or autotrophic.

The third feature can be their mode of respiration which can be either anaerobic or aerobic. Another feature is the composition of cell wall. The cell wall can be either peptidoglycan or lipopolysaccharide cell wall.

Water vapor rising refers to the process by which water molecules in the air become more energetic and move more freely, causing them to rise higher in the atmosphere. This can occur as a result of several different factors, including:

1. Temperature: Water vapor will tend to rise in the atmosphere if it is warmer than the surrounding air. As the water molecules absorb heat energy, they become more energetic and are able to move more freely, causing them to rise.

2. Humidity: Water vapor will also tend to rise in the atmosphere if the air is already saturated with moisture. When the air becomes saturated, any additional water vapor that is added to it will be less likely to stay in the air and will instead tend to condense and fall to the ground.

3. Pressure: Water vapor will also tend to rise in the atmosphere if the air pressure is lower at higher altitudes. As the water molecules rise and the air pressure decreases, they become more energetic and are able to move more freely, causing them to rise further.

Overall, water vapor rising is an important process in the Earth's atmosphere that helps to distribute heat and moisture around the planet and to regulate the Earth's climate.

Natural resources are anything that can be obtained from the environment for human needs. The more the population increases, the more natural resources are used to meet needs.

For example, food, clean water, clean air, and other needs. If the population increases, various problems will arise, for example, traffic flow density which causes air pollution, many agricultural lands being used as residential areas resulting in slums, and finally clean water becomes a problem.

Sucrose will not yield a positive Fehling's test

A reducing sugar, or a sugar that can reduce copper ions, is detected using the ideal Fehling's test. Fehling's solution, which consists of copper(II) sulphate and a strong base, is mixed with a sugar solution to be tested, and the mixture is then heated.

During this process, the copper ions will be reduced to copper(I) oxide if a reducing sugar is available, and this copper(I) oxide will then react with the strong base to generate a precipitate of copper(I) hydroxide, which will change its color to red. A positive Fehling test result would be produced by reducing sugars like lactose, maltose, and other disaccharides, but not by non-reducing carbohydrates like sucrose.

Answer: The assertion is true and the reason is the correct explanation of the assertion

Explanation: This statement is true because the plasma membrane is selectively permeable, meaning that it allows some substances to pass through it while preventing others from crossing it. Gases like oxygen and carbon dioxide are small molecules that can easily diffuse through the membrane due to their size and lack of charge. Additionally, the plasma membrane has channels and pumps that specifically facilitate the movement of gases across the membrane. Therefore, metabolic gases can freely diffuse across the plasma membrane due to the permeability of the membrane.

If the apple snail population were to decrease, the limpkin, a secondary consumer that eats mainly apple snails, would have to find an alternative food source in order to adapt to its environment. This could involve finding other types of snails or mollusks to eat, or potentially switching to a diet that includes other types of prey. The limpkin may also need to range over a larger area in order to locate sufficient food, or it may need to change its foraging behavior in order to more effectively locate and capture its preferred prey. Ultimately, the limpkin's ability to adapt to a decline in the apple snail population will depend on the availability of other suitable food sources and the flexibility of its foraging behavior.
