Answer:

In immunology, an antigen is a molecule or molecular structure, such as may be present on the outside of a pathogen, that can be bound by an antigen-specific antibody or B-cell antigen receptor. The presence of antigens in the body normally triggers an immune response. Wik

A. the humans breeding the animals

Explanation:

It says in there that it interferes with the natural animal processes so it probably doesn't help the animal, and it also said in there that we have breed for more desirable traits in other words we bred them to be more useful to us and give us benefits.

Answer: The answer in scientific notation is [tex]4.84\times 10^{14}[/tex]

Explanation:

The conversion factor is : [tex]1km^3=10^{12}L[/tex]

Given : Volume of liquid in Lake Erie = [tex]484km^3[/tex]

To find : Volume of liquid in Lake Erie in units of liters

As [tex]1km^3=10^{12}L[/tex]

Thus [tex]484km^3=\frac{10^{12}}{1}\times 484=484\times 10^{12}L[/tex]

The answer in scientific notation is [tex]4.84\times 10^{14}[/tex]

Answer:

2) an ocean trench

Explanation:

Ocean trench is a commonly formed at a plate boundary where oceanic crust converges with continental crust.

Long, narrow depressions on the seafloor are known as ocean trenches. These chasms are among the deepest natural places on Earth and the deepest portions of the ocean.

Every ocean basin on the planet has ocean trenches, but the deepest ones encircle the Pacific Ocean as part of the so-called "Ring of Fire," which is also home to active volcanoes and earthquake-prone regions. Tectonic activity, which refers to the movement of the Earth's lithosphere, is what causes ocean trenches.

Ocean trenches in particular are a characteristic of convergent plate borders, which occur where two or more tectonic plates collide. In a process known as subduction, dense lithosphere melts or slides beneath less dense lithosphere along numerous convergent plate borders, forming a trench.

Therefore, Ocean trench is a commonly formed at a plate boundary where oceanic crust converges with continental crust.

Answer:An adaptation can also be behavioral, affecting the way an organism responds to its environment.

Explanation:

An example of a structural adaptation is the way some plants have adapted to life in dry, hot deserts. Plants called succulents have adapted to this climate by storing water in their short, thick stems and leaves.

Answer:

The two chromosomes in a homologous pair are very similar to one another and have the same size and shape. Most importantly, they carry the same type of genetic information: that is, they have the same genes in the same locations.

Answer:

Example of potential energy being transformed into kinetic energy  will be; Holding a ball in your hands and then throwing it down a hill. The move of the ball as being transformed to kinetic energy.  

Explanation:

Potential and kinetic energy are two forms of energy that can be converted into each other.   Potential energy is the energy held by an object because of its position relative to other objects or its electric charge. While kinetic energy of an object is the energy that it possesses due to its motion.

Answer: 1. Mitosis

2. Answer A.

Explanation:

Stick insects that reproduce asexually are less biologically diverse because they can't evolve as quickly as species that reproduce sexually can. Thus, option A is correct.

Asexual reproduction, in contrast to sexual reproduction, only contributes to genetic variety in the population if a chance mutation in the organism's DNA is passed on to the progeny.

Evolution can occur gradually. Asexual creatures often evolve relatively quickly following a dramatic mutation and do not need as many generations to accumulate adaptations as do populations that reproduce sexually.

Asexual reproduction has the benefit of allowing for rapid population growth under the right circumstances. You only require one parent. Since you don't require a partner, it is more time and energy efficient.

Therefore, new organisms are usually genetically identical to the parent.

Answer:

Mitosis consists of four basic phases: prophase, metaphase, anaphase, and telophase. Some textbooks list five, breaking prophase into an early phase (called prophase) and a late phase (called prometaphase).

1) Prophase: chromatin into chromosomes, the nuclear envelope break down, chromosomes attach to spindle fibres by their centromeres 2) Metaphase: chromosomes line up along the metaphase plate (centre of the cell) 3) Anaphase: sister chromatids are pulled to opposite poles of the cell 4) Telophase: nuclear envelope ...
