The food energy pyramid is the type of pyramid that shows the flow of energy within the trophic levels of an ecosystem.

In a typical food energy pyramid, the organism with the highest energy level is usually located lowest in the pyramid while the organism that obtained the lowest energy is at the uppermost part of the pyramid.

There are various types of food pyramids which include the following:

From the given diagram, each level is being represented by the energy they acquired when they feed on the lower placed organisms.

Therefore, when humans feed on the trout that fed on the smelt that fed on the zooplankton that fed on the algae, they will only obtain 1.2 calories of the 1000 calories possessed by algae and bacteria.

A typical mechanism of disease development and a prognostic factor for malignant tumors is developed resistance to prostate cancer treatments. Resistance to MTAs, such as the taxane Docetaxel, determines treatment failure and the progression of the disease into lethal stages.

The variety of processes causing acquired resistance has been investigated for decades, but they remain poorly understood, which severely restricts the creation of novel therapeutic approaches. We outline a procedure for creating Docetaxel-resistant prostate cancer cell lines in this article.

The Docetaxel-resistant cell lines created by this method have been successfully used in recent studies, such as the loss of resistance properties over time, and they present an opportunity to enhance our knowledge of the molecular mechanisms behind acquired chemoresistance in deadly prostate cancer.

An immunity used by human body is: (2) humoral immunity antibody mediated.

Immunity is the ability of the body to fight against the foreign invaders and the disease caused by them. This immunity can be active or passive. Active immunity is the one that the body develops by itself. Passive immunity is the one that is introduced into the body by injecting antibodies.

Humoral immunity is the response mediated by the antibodies present in the body for specific pathogens. It is driven by the B cells. Antibodies are the Y-shaped structures that are produced by the B cells in response to the invasion of certain foreign invaders also called the antigens.

The fascicles of the biceps brachii run in the same direction as the long axis of the muscle, and it's the muscle belly that is so distinctive when someone contracts this muscle. Considering this information, the biceps brachii is an example of a parallel muscle.

The ventral part of the upper arm has a big, muscular muscle called the biceps brachii.The muscle is made up of a long head (caput longum) and a short head (caput breve) (caput longum). The biceps muscle has two joints. Both muscles' head partially constrains opposite motions at the shoulder joint. While the short head pulls the arm back towards the trunk, the long head pushes the arm away from the trunk (abduction) and rotates it inward (inward rotation) (adduction).

Strap muscles are a type of parallel muscle because their fibers, as their name implies, run parallel to one another. Although they are not very strong, they have good endurance. They are often lengthy muscles that create significant movements. Sartorius and Sternocleidomastoid are two examples.

Answer: The Correct answer is 3) Negatively charged electrons can move freely through a metal

Explanation:

The electric current can pass easily through a metal because the electrons or negatively charged ions are relatively free to move in metals. So, whenever current pass-through metals, electrons carry electricity and pass it through the metal. The movement of these electrons are the reason for conduction of current in metals.

The object which is having greater mass will have greater KE if gravity is neglected. Cause kinetic Energy is directly proportional to the mass of the object.

Now on rolling down the slide the one which is rolled from a greater height will have greater potential energy will eventually have greater kinetic energy.

The energy that an object has as a result of its ongoing motion is known as kinetic energy in terms of physics. It is described as the effort required to move a mass-determined body from rest to the indicated velocity.

The body holds onto the kinetic energy that it acquires during this acceleration until and unless its speed changes. Kinetic energy has the following formula: K.E. = ½ m v2, where m is the object’s mass and v are its square velocity.

The kinetic energy that is measured in kilograms-meters then squared per second squared if this mass is then measured in kilograms and the velocity is then measured in meters per second.

When potential energy is released, among other catalysts such as elastic forces or gravity, kinetic energy is produced.

Disruptive (diversifying) selection has taken place in this population. The correct answer is option(d).

Diversifying selection, also known as the disruptive selection, happens when extreme levels of a trait are preferred above the middle values. Often, speciation is driven by this kind of selection. Additionally, environmental changes that favor people at one extreme of the phenotypic spectrum might result in diversifying selection.

Disruptive selection is important because it has the ability to create a population with such a high level of diversity that it results in the speciation of new species, including ecological sexual dimorphism. Since more than one phenotype, or physical attribute, is preferred by the disruptive selection, genetic and phenotypic diversity in a population rises. As a result, diversified selection is another name for disruptive selection. Disruptive selection has the potential to trigger speciation over time.

The gene in the middle is R in a three-point testcross if the most abundant classes are rqh and rqh and the rarest classes are rhq and rhq.

The locations of three genes in the genome of an organism are identified using a three-point cross. A homozygous recessive individual is crossed with a person who is heterozygous for three mutations, and the progeny's phenotypes are graded. The parental gametes produce the two most prevalent phenotypes, while a double-crossing during gamete creation produces the two least prevalent phenotypes. The geneticist can identify which gene is situated between the other genes on the chromosome by comparing the phenotypes of the parental and double-crossover individuals. The most prevalent phenotypes are rqh and rqh while the least prevalent phenotypes are rhq and rhq, therfore the middle gene after comparing is R.
