Answer:

Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. ... A typical species becomes extinct within 10 million years of its first appearance, although some species, called living fossils, survive with little to no morphological change for hundreds of millions of years.

Explanation:

# CAUSES OF ANIMAL EXTINCTION

Demographic and genetic phenomena.

Destruction of wild habitats.

Introduction of invasive species.

Climate change.

Hunting and illegal trafficking.

# Basic causes of extinction are as follows

2. Excessive hunting and killing of wild animals.

3. Poaching for purpose of meat, skin, fur, ivory, and rhino horns etc.

4. Capture and export of new species in large number.

5. Introduction of exotic species.

6. Excessive use of pesticides, fungicides, and other toxic chemicals.

7. Conversion of fertile land in the desert by overgrazing of domestic animals.

8. Deforestation leading to loss of covers or shelter to wild animals.

9. Excessive use of plant wood for timber, charcoal or fire purpose.

Answer:

The tissues of multicellular, complex animals are four primary types: epithelial, connective, muscle, and nervous. Recall that tissues are groups of similar cells group of similar cells carrying out related functions.

Explanation:

.

The percentage of water inside the cell is 2.5 %. Water will move into the cell and it will swell. So it's a hypotonic solution.

Osmosis is the spontaneous diffusion or flow of water or other liquids over a semipermeable membrane, or one that prevents the passage of solutes, or dissolved compounds. The crucial biological mechanism was initially in-depth investigated in 1877 by German plant physiologist Wilhelm Pfeffer. Inaccurate investigations of leaky membranes, such as animal bladders, and the movement of water and other chemicals through them were previously conducted by other researchers.

A solution will tend to become more diluted by absorbing solvent through a membrane separating it from the pure solvent if the membrane is permeable to the solvent but not to the solute. The osmotic pressure, also known as the pressure exerted on the solution, can be raised to a certain level to halt this process. Jacobus Henricus van 't, Hoff, a Dutch-born chemist, demonstrated in 1886 that Henry's rule is obeyed if the solute is sufficiently diluted that its absolute vapor pressure is above the solution.

Therefore, the percentage of water inside the cell is 2.5 %. Water will move into the cell and it will swell. So it's a hypotonic solution.

Answer:

Sunlight, water, carbon dioxide, dirt/soil

Explanation:

Birds that detect UV light have favorable characteristics that enable them to survive and reproduce. These  characteristics are passed on to their offspring.

According to Darwin's theory of evolution, organisms that are better adapted to their environment live long enough to survive and reproduce and pass on these favorable traits to their offspring.

Since birds depend on these fruits for food and these fruits reflect UV light. A bird that can not detect UV light will find it difficult to obtain food. Hence, birds that have developed the ability to detect UV light will live long enough and reproduce, passing on these favorable characteristics to their offspring. Hence, birds that can detect UV light appears from birds who do not originally detect UV light.

See explanation section for answer:

Explanation:

The left side of the heart contains the left atrium which allows oxygen rich blood to flow through the mitral valve and into the left ventricle. Whereas the right side of the heart contains the right atrium which allows the blood with poor oxygen levels to enter the right ventricle through the tricuspid valve.

Also, the left ventricle is larger than the right ventricle because the left ventricle is responsible for pumping the fresh oxygen rich blood throughout the body.

Answer:

Protons flow down their concentration gradient into the matrix

Explanation:

The proton gradient produced by proton pumping during the electron transport chain is used to synthesize ATP. Protons flow down their concentration gradient into the matrix through the membrane protein ATP synthase, causing it to spin (like a water wheel) and catalyze conversion of ADP to ATP.

Answer: we know that the same temperature was named 0°C and 32°F. We write it 0°C = 32°F, and read it: "A temperature of zero degrees Celsius is the same as a temperature of 32 degrees Fahrenheit." Similarly, 0°F = 160/9°C. ... 23°C is 23°C above 0°C. But 23°C = 23*1.8°F and 0°C = 32°F.

Explanation: Mark me brainly please

Answer:

They are the same

Explanation:

(0°C × 9/5) + 32 = 32°F

To convert temperatures in degrees Celsius to Fahrenheit, multiply by 1.8 (or 9/5) and add 32.

Osmosis: Osmosis is the movement of solvent particles across a semipermeable membrane from a dilute solution into a concentrated solution. ... Diffusion: Diffusion is the movement of particles from an area of higher concentration to lower concentration.

Living beings are organisms that can respire, respond, grow, reproduce, and are made of cells. All living things have a genetic code. Thus, option B is correct.

A genetic code is a sequence of proteins and nucleic acids that act as a hereditary molecule that transfers the traits and characteristics to the progeny.

The code can be in the form of DNA or RNA and provides information about the genotype of the organisms that were passed from their ancestors.

The genetic code is in the form of triplets and is a universal system that codes for the same proteins in all organisms. It consists of the nitrogenous bases that through translation make the amino acids.

Therefore, option B. all living organisms have a genetic code.
