Each element on the periodic table is represented by its element symbol and atomic number.

Explanation:

The periodic table is the list of known chemical elements. The atomic number of an element is the same as the number of protons in the particular nucleus of an atom.

The elements in the periodic table are arranged into periods and groups. A row of elements across the table is called a period.

In a periodic table element is listed by its symbol and atomic number. For example "H" denotes hydrogen, "Li" denotes lithium.

The elements in the same group represents the patterns in atomic radius, ionization energy and electronegativity. The elements are represented by 2 letters one capital and other in lower case. they are arranged based on the increased atomic number.

What are the ways in which captive breeding helps protect biodiversity? Check all that apply
IgorLugansk [536]

Answer:

Following are the ways captive breeding helps conserve biodiversity:

  1. Captive breeding can increase population numbers
  2. Captive breeding can help remove species from the Endangered Species List
  3. Captive breeding can result in the eventual release of offspring into the wild.

Explanation:

Captive Breeding:

Captive breeding is an ex-situ conservation technique (taking the animal out of its natural habitat to increase population numbers in zoos or sanctuaries). Captive breeding involves selective breeding of endangered species to help produce a sizable population that can later be introduced back into the wild when their habitat improves.

Captive breeding programs include zoos, sanctuaries located away from the animal's original habitat. For example, the Toronto Zoo has operated a captive breeding program for the Blanding's turtle since 2012. The turtles are kept their for 2 years after birth and then released back into the wild.

If a magnet is attracted to a metal object what can you say about the pole of the magnet and the pole of the object?
Nikolay [14]

Answer:

A. The poles are opposite

Explanation:

Magnets are object that produce magnetic fields, which are regions of space that exert a forces on charged particles in motion or on other magnets.

Every magnet has 2 opposite poles, which are labelled by convention as North Pole and South Pole; the lines of the magnetic field of a magnet go out from the North Pole and go into the South Pole.

Magnetic poles always exist in pair: it means, every magnet always contains a North Pole and a South Pole. If a magnet is cut in a half, each half of the magnet will still have a North Pole and a South Pole.

Each pole exerts a force on another pole; in particular, we have:

- Like poles (north-north or south-south) repel each other

- Opposite poles (north-south) attract each other

In this problem, a magnet is attracted to a metal object: this means that the two poles must be of opposite polarity. Therefore, the correct option is

A. The poles are opposite

Which kind of solution is the concentration of solutes the same inside and outside of the cell?
Readme [11.4K]

Answer:

D. Dynamic equilibrium

Explanation:

Equilibrium is when the amount of solution outside the cell is equal to the amount inside. A dynamic equilibrium is when this homeostasis is kept through a continuing process. Therefore, since homeostasis is constantly being maintained the solution will be equal on both sides of the cell.
