Explanation:

Wash your hands often. This is especially important before and after preparing food, before eating and after using the toilet.

Get vaccinated. Immunization can drastically reduce your chances of contracting many diseases. Keep your recommended vaccinations up-to-date.

Use antibiotics sensibly. Take antibiotics only when prescribed. Unless otherwise directed, or unless you are allergic to them, take all prescribed doses of your antibiotic, even if you begin to feel better before you have completed the medication.

Stay at home if you have signs and symptoms of an infection. Don't go to work or class if you're vomiting, have diarrhea or are running a fever.

Explanation:

Ecological succession is the process of change in the species structure of an ecological community over time. The time scale can be decades (for example, after a wildfire), or even millions of years after a mass extinction.[1]

Succession after disturbance: a boreal forest one year (left) and two years (right) after a wildfire.

The community begins with relatively few pioneering plants and animals and develops through increasing complexity until it becomes stable or self-perpetuating as a climax community. The "engine" of succession, the cause of ecosystem change, is the impact of established organisms upon their own environments. A consequence of living is the sometimes subtle and sometimes overt alteration of one's own environment.[2]

It is a phenomenon or process by which an ecological community undergoes more or less orderly and predictable changes following a disturbance or the initial colonization of a new habitat. Succession may be initiated either by formation of new, unoccupied habitat, such as from a lava flow or a severe landslide, or by some form of disturbance of a community, such as from a fire, severe windthrow, or logging. Succession that begins in new habitats, uninfluenced by pre-existing communities is called primary succession, whereas succession that follows disruption of a pre-existing community is called secondary succession.

Succession was among the first theories advanced in ecology. Ecological succession was first documented in the Indiana Dunes of Northwest Indiana and remains at the core of much ecological science.[3]

Answer:

population I stars.

Explanation:

A star is a giant astronomical or celestial object that is comprised of a luminous sphere of plasma, binded together by its own gravitational force.

It is typically made up of two (2) main hot gas, Hydrogen (H) and Helium (He).

The luminosity of a star can be defined as the total amount of light radiated by the star per second and it is measured in watts (w). Also, the apparent brightness of a star is a measure of the rate at which radiated energy from a star reaches an observer on Earth per square meter per second. The apparent brightness of a star is typically measured in watts per square meter.

Some of the examples of stars are; Canopus, Sun (closest to the Earth), Betelgeus, Antares, Vega etc.

New stars that are found in the spiral arms and formed from recycled dead star material are known as population I stars. Also, it comprises of association and clusters formed a million or billion years ago in the spiral arms of Milky Way galaxy.

A galaxy can be defined as a collection or group of many billions of stars and other planetary body which are existing independently.

Answer:

Insect larvae and shrews

Answer: c. 50%

Explanation:

If you draw a punnett square you see that the phenotypes you get are Cc, Cc, cc, and cc. If C (curly hair) is dominant over c (straight hair) then those with the phenotype Cc would have curly hair and those with the phenotype cc would have straight hair. 2 out of 4 have Cc (curly hair) so that's 50%.

Answer:

embryonic stem cells

Explanation:

I prefer embryonic stem cells instead of adult stem cells because embryonic stem cells can be differentiate into any cell type whereas adult stem cells can't be differentiated into other cell type. Due to this feature of embryonic stem cells, it can be used for the therapy and the disease can be cured with the help of these embryonic stem cells. So I prefer embryonic stem cells due to their unique ability of differentiation into any type of cell.

Answer:

Evolution means change in the physical features of an organism.

Explanation:

Evolution means change in the physical features of an organism. Evolution occurs in the population of an organisms due to various factors such as mutation, non-random mating and natural selection. Nonrandom mating occurs when an organism prefer mating with particular superior organisms or with the similar organism. Mutation in the genetic makeup of an organism is also responsible evolution. this mutation occurs when an organism experience ultraviolet radiation from the sun, or also occur if an error in DNA during cell division. Gene flow is also known as gene migration is the transfer of genetic material or traits from one population to another when the organism is migrated to another environment. Some organisms are selected naturally because they have the potential to survive in that environment so they survive and that doesn't adopt itself to the environment, it will extinct from the environment.

Answer: Caterpillars and Meadow voles

Answer:

before the common ancestor of all extant life.

Explanation:

Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.

Heredity refers to the transfer of traits (specific characteristics) from the parent of a living organism to her offspring through sexual reproduction or asexual production. Some examples of hereditary traits are dimples, tongue rolling, baldness, handedness, freckles, curly hair, color blindness, height, etc.

Basically, deoxyribonucleic acid (DNA) is an organic complex-molecular structure found in all living organisms. It comprises of genes and is essentially the foundation block of all living organisms such as humans, animals and plants.

The current genetic code evolved before the common ancestor of all extant life i.e that are still in existence or alive.

Answer:

Answer:Fossil fuels are the largest sources of energy for electricity generation. Natural gas was the largest source—about 38%—of U.S. electricity generation in 2019.

Answer:Fossil fuels are the largest sources of energy for electricity generation. Natural gas was the largest source—about 38%—of U.S. electricity generation in 2019.Explanation:

Answer:Fossil fuels are the largest sources of energy for electricity generation. Natural gas was the largest source—about 38%—of U.S. electricity generation in 2019.Explanation:The United States uses many different energy sources and technologies to generate electricity. The sources and technologies have changed over time, and some are used more than others. The three major categories of energy for electricity generation are fossil fuels (coal, natural gas, and petroleum), nuclear energy, and renewable energy sources. Most electricity is generated with steam turbines using fossil fuels, nuclear, biomass, geothermal, and solar thermal energy. Other major electricity generation technologies include gas turbines, hydro turbines, wind turbines, and solar photovoltaics.

Natural gas is used in steam turbines and gas turbines to generate electricity.Coal was the second-largest energy source for U.S. electricity generation in 2019—about 23%. Nearly all coal-fired power plants use steam turbines. A few coal-fired power plants convert coal to gas for use in a gas turbine to generate electricity.

Answer:

Compressibility is reducing the volume by increasing the pressure of a substance like liquid or gas. It is a physical characteristic of a substance especially gases.

Everyday life examples:

(1) LPG - These gas cylinders have compressed natural gas to liquid gas to store and use as fuels.

(2) Tubes of bicycles are filled by the pumps that compress the air.

(3) Carbonated soda filled with the help of compressing the carbon dioxide into the bottle.

4) oxygen bottles in medical institutes for helping the patient to breathe.
