Heterotrophs are consumers, cannot make their own foods, and have some of them have the capacity to consume autotrophs. Hence, they are not at the base of most food webs.

Heterotrophs are organisms that have no capacity to manufacture their own foods, unlike autotrophs.

They depend on other organisms for their foods. Hence, they are known as consumers, unlike autotrophs that are called producers.

Heterotrophs are of different types:

Thus, heterotrophs do not occupy the base of food webs. The base of food webs are mostly occupied by autotrophs, the producers.

Heterotrophs are at the base of most food webs is the statement that is false.

Therefore, we can conclude that autotrophs are considered producers and are at the base of most food webs, while heterotrophs are considered consumers which could not survive without feeding on other organisms.

DNA evidence and the fossil record indicate are the ancestors of the living cetaceans were land-dwelling mammals. DNA evidence allows to trace the evolutionary origin of taxonomic groups.

DNA evidence refers to the linear order of nucleotides, which can be used to trace the evolutionary origin of a particular taxonomic group.

When the linear order of DNA nucleotides is conserved, it is known as sequence homology.

Fossils are preserved remains of organisms that once lived on the Earth, which can also be used as evidence to trace the evolutionary origin of a given group.

The first part of the small intestine is called duodenum

Explanation:

The small intestine is a tightly folded tube which connects to the stomach on the top end and to the large intestine on the bottom end.

The small intestine consists of three parts:

Duodenum is responsible for completing the first phase of digestion. In this section of the intestine, food is mixed with enzymes and bile which help break down food.

Answer:

Duodenum

Explanation:

Duodenum is the first part where most of the small intestine digestion happens

Phytohormones are responsible for the movement of plant towards stimulus. Auxin is the main phytohormone responsible for gravitropism and phototropism of plants.

Plants are immobile however different parts of the plant show movements in response to the stimulus in the environment. The chemicals present in the plant body which are responsible for these movements are called phytohormones or plant hormones.

Auxins are the main hormones responsible for the cell elongation in plants.  Auxins are responsible for the phototropism (movement of plant parts in response to light) and gravitropism (movement in plants in response to gravity).

Roots of a plant grow downward and exhibit positive gravitropism whereas stems on the other hand, exhibit negative gravitropism since they grow upwards and against the gravity. If you place a plant on its side or even upside down, the stem will curve its way up in response to gravity and auxin is responsible for this movement.

Structure S is a simple columnar epithelium, which is a type of tissue.

The diagram shows the structures that form the surface of the trachea. The trachea is a tube that carries air from the lungs. The surface of the trachea is lined with a layer of tissue called the epithelium. The epithelium is made up of cells that line the inside of the trachea.

The structure labelled S is a type of epithelium called a simple columnar epithelium. Simple columnar epithelia are made up of cells that are arranged in a single layer. The cells in a simple columnar epithelium are tall and column-shaped.

The simple columnar epithelium in the trachea helps to protect the trachea from infection. The cells in the epithelium produce a mucus that traps dust and other particles. The mucus is then carried away by the cilia, which are tiny hairs that line the trachea.

The other levels of organization in the diagram are organ, organ system, and cell. The trachea is an organ, which is a collection of tissues that work together to perform a specific function. The respiratory system is an organ system, which is a group of organs that work together to perform a common function. Cells are the basic units of life, and they are the building blocks of tissues, organs, and organ systems.

Answer:

Fungus

Explanation:

Chitin is a fibrous substance consisting of polysaccharides and forming the major constituent in the exoskeleton of arthropods and the cell walls of fungi. This would point to it most likely being a fungal agent. Hope this helps!

Chitin is a natural polymer and a nitrogenous carbohydrate. The cell walls of fungus pathogens are formed of the N-acetylglucosamine polymer chitin.

Pathogens are germs that enter, grow, and cause sickness in their host's body. It simply needs a host body to live.

Pathogens have the ability to circumvent the immune system. It likewise relies on body chemicals to survive. Depending on the kind, these bacteria can move from one host to another in a variety of ways.

The plant is home to millions of fungus species. Not all of them are pathogenic. Only roughly 300 of them are capable of causing disease. Fungi can be found on the surface of your skin or inside your food. They only cause illness if they overgrow.

Fungi have two protective layers, a membrane, and a cell wall, and they are difficult to destroy. The severity of a fungal infection might vary.

Thus, we can conclude that the unknown pathogenic organism is fungus because fungus pathogens contain chitin.

all cells life begin and end with this process by the process of meiosis

Meiosis is the process  where a single cell divides twice to produce four four haploid daughter cells which are otherwise called as gametes; It can occur in two substages such as meiosis I and meiosis II.

Humans have 46 chromosomes in every cell,  where 23 chromosomes t came from one of our parents and 23 very similar chromosomes that came from the other parents.

Meiosis I consist of substages like Prophase I where nuclear envelope disintegrates, Chromosomes begin to condense, Spindle fibres appear.

Secondly Prometaphase I where Spindle fibres attach to the  centromere followed by Metaphase I where The homologous chromosomes align at the equatorial plate, Anaphase I where he homologous chromosomes move towards the opposite poles.

Telophase I where Spindle fibres disappear, Cytokinesis I where the cytoplasm and the cell division result in 2 non-identical haploid daughter cells.

Explanation:

For example,The density of seawater depends on the content of salt. It is known that the density of salt is 2.165g/cm3, so the more salt, the greater the density of mixed liquid.

Answer:If you know that dissolution of salt only marginally affects the volume of the solution, how would you expect the density to evolve? It should reasonably increase.

Explanation:

at a given temperature, Should salts be dissolved in the water, and the volume remains reasonably constant, the density

. A solute binds water molecules around itself in a coordination sphere, and should a salt be dissolved, both anion and cation must be solvated; hence an increase in solution density with respect to water.
