There you go!

Answer:

It is hard to answer

Explanation:

Some people yes and some people no if you go back to 1899 where everything wasn't as polluted as now you'd be amazed so to answer your question no not all humans have negative impacts on the environment.

Answer:

No

Explanation:

Not always, But I have to say that the negative outweighs the positive.

- People have a positive affect on the environment by Recycling,

Reforestation, making green and open space laws, and having environmental regulations to protect the environment and keep it clean.

Answer:

food chain, in ecology, the sequence of transfers of matter and energy in the form of food from organism to organism. Food chains intertwine locally into a food web because most organisms consume more than one type of animal or plant.

Explanation:

Answer:

Food Chain

Reason :

A food chain is a system of linkages in a trophic chain that begins with primary producers and ends with a top predator, organisms feeding on organic matter , or organisms feeding on non-organic matter . A food system clearly demonstrates ways creatures are tied to one another by their food consumed.

Answer:

Codominance means that neither allele can mask the expression of the other allele. An example in humans would be the ABO blood group, where alleles A and alleles B are both expressed. So if an individual inherits allele A from their mother and allele B from their father, they have blood type AB.

Following are the statements which describe Kingdom Archaebacteria:

Archaebacteria are a group of primitive microorganisms that are distinct from other bacteria. They are considered to be some of the oldest life forms on Earth and have unique metabolic processes that allow them to survive in extreme environments, such as high temperatures, acidic conditions, and environments with little oxygen.

They are found in diverse environments, including hot springs, salt lakes, and deep-sea vents. Archaebacteria play a crucial role in maintaining the balance of Earth's ecosystems, serving as primary producers and decomposers in some of the harshest environments on the planet.

Answer:

Carnivore

Explanation:

Carnivores are organisms that eat meat. So, organisms that mostly eats meat or the Flesh of other animals would be "carnivores."

Common examples of carnivores would be Tigers, Sharks, Lions, crocodiles, and honey badgers. You also have herbivores, and omnivores which are animals who eat rather plants, or both plants AND animals. Common examples of herbivores would be something like a hippo. While a common example of an omnivore would be a bear.

The biotechnological processes that are described in the table are as follows:

Thus, the correct option for this question is D.

Biotechnological processes may be defined as those techniques that are significantly utilized by live organisms or enzymes from organisms in order to produce products and processes useful to humans.

Process one describes the facts and principles of the artificial selection through which a high-yielding wheat variety with a disease-resistant wheat variety is produced with a desirable outcome.

Process two describes the facts and principles of genetic engineering through which the insertion of bacterial toxin takes place due to which the production genes in cotton may alter.

Therefore, the correct option for this question is D.

Explanation:

Answer:

making seeds.

Explanation:

Yes, position is relative and therefore movement is relative. Uniform motion (constant speed in a straight line) is relative, but changes in motion (speed or direction) are not. If one observer speeds up, slows down or changes direction, he feels the forces that cause that change; other observers do not.

Answer:

Photosynthesis is the name given to the set of chemical reactions performed by plants to convert energy from the sun into chemical energy in the form of sugar. Specifically, plants use energy from sunlight to react carbon dioxide and water to produce sugar (glucose) and oxygen.

Explanation:

Answer:

The product of photosynthesis that plants make as a source of energy for their life functions is oxygen. This substance allows the body to function because it is an important reactant in cellular respiration, which is what keeps us alive. If plants disappeared from Earth, all other forms of life would undoubtedly be affected. Many animals that rely on oxygen to survive would be impacted and those species might go extinct. And even life forms that don't necessarily or directly rely on the oxygen produced by plants would feel an effect through the food web. The food web extends to all life forms that exist on Earth, and the disappearance of an integral member of the food web such as the entire plant kingdom would cause a ripple effect that would worsen almost every single life form's living situation.
