Explanation:

When a habitat is destroyed, the carrying capacity for indigenous plants, animals, and other organisms is reduced so that populations decline, sometimes up to the level of extinction. Habitat loss is perhaps the greatest threat to organisms and biodiversity.Extinction happens when environmental factors or evolutionary problems cause a species to die out. The disappearance of species from Earth is ongoing, and rates have varied over time.

Extinctions are associated with biodiversity changes, thereby affecting species expansion.

Extinction refers to the disappearance of a given taxonomic group (e.g. species-level extinction).

In conclusion, extinctions are associated with biodiversity changes, thereby affecting species expansion.

Answer:

Asexual reproduction.

Explanation:

The generation of genetically identical offspring from a single parent, without the fusion of sperm and egg, is called asexual reproduction. Asexual reproduction occurs when there is only one parent from which organism is produced. Budding, binary fission and fragmentation are the different types of asexual reproduction that involves only one parent and no fusion of sperm and egg cells.

Answer: Cancer can spread anywhere through the body, but it's most likely to spread to lymph nodes, bones, the brain, the liver or the lungs.

Explanation:

Answer:

See below

Explanation:

Cancer can cause discomfort and loss of function in a specific section of the body by compressing surrounding nerves. Headaches and stroke-like symptoms and indications, such as weakness on one side of the body, are common symptoms and indicators of cancers that damage the brain.

Cancer may spread to any region of the body, although lymph nodes, bones, brain, liver, and lungs are the most commonly affected.

Answer: An ecological footprint is a means of understanding resource availability and usage. The correct option is B.

Explanation:

The ecological footprint is a method which is used to measure the rate as which humans use natural resources in their environment and generate waste from them compared with how fast nature can absorb these wastes and generate the used resources again. The productive areas which are measured through this means are:

--> cropland,

--> grazing land,

--> fishing grounds,

--> built-up land,

--> forest area, and carbon demand on land.

The importance of ecological footprint to the environment should no the over emphasizes. When properly observed, different environmental pollution would be dealt with. Generally, there would be:

--> decreased desertification,

--> decreased global warming

--> availability of fresh unpolluted air and

--> decreased carbon emissions.

GMOs are created by selecting and inserting a particular gene into a plant to produce a desired trait – such as resistance to pesticides. ... This type of selective or traditional breeding involves crossing thousands of genes, which is different than how gmos are made.

Explanation:

Answer:

GM is a technology that involves inserting DNA into the genome of an organism. To produce a GM plant, new DNA is transferred into plant cells. Usually, the cells are then grown in tissue culture where they develop into plants. The seeds produced by these plants will inherit the new DNA.

What are oceanic features?

Features of the ocean include the continental shelf, slope, and rise. ... Below the ocean floor, there are a few small deeper areas called ocean trenches. Features rising up from the ocean floor include seamounts, volcanic islands and the mid-oceanic ridges and rises.\

The air we breathe: The ocean produces over half of the world's oxygen and absorbs 50 times more carbon dioxide than our atmosphere. Climate regulation: Covering 70 percent of the Earth's surface, the ocean transports heat from the equator to the poles, regulating our climate and weather patterns.

The concept of fraction

Explanation:

What is the concept of fraction tho? Fractions are numbers that represent a part of the whole. When an object or a group of objects is divided into equal parts, then each individual part is a fraction. ... It is divided into a numerator and denominator where the denominator represents the total number of equal parts into which the whole is divided.

A fraction represents the number of parts that we take from a unit that is divided into equal parts. It is represented by two numbers separated by a fraction line.

Answer:

Plants use electric fields to communicate with bees, scientists have learned.

Bumblebees are able to find and decipher weak electric signals emitted by flowers, according to the study.

Tests revealed that bees can distinguish between different floral fields, as if they were petal colours. The electric signals may also let the insects know if another bee has recently visited a flower.

Explanation:

How bees detect the fields is unknown, but the researchers suspect the electrostatic force might make their hair bristle. A similar hair-raising effect is seen when placing one's head close to an old-style TV screen.

Flowers were already known to use bright colours, patterns and enticing scents to attract pollinators.
