Answer:

hehe i just finished answer a question about pollution sooo here you go :) this is just an example and not a full essay I recommend adding more evidence!! (please write in your own words)

Pollution has been a problem for over 2,000 years now. There are many things that are causing pollution. For example firecrackers!

Using firecrackers can be very dangerous not just for us, but the environment as well. Firing crackers can increase the concentration of dust and pollutants in the air. After firing, the fine dust particles settle on the surrounding surfaces which are packed with chemicals like copper, zinc, sodium, and lead. Now you may think oh so it's bad for the air so what? If the air is polluted, trees and plants that give us oxygen can't do their job. If they can't do their job we can't breathe or live. Most of the chemicals that are bad for the air are in firecrackers. These chemicals can last for hours or days on end, exposing you and your neighbors to possible long-term health problems. Then fireworks also have the potential of starting wildfires. About 7,500 to 10,600 trees were burnt down (10% to 14% of trees) in California alone due to wildfires. About 19,500 trees were burnt down just from fireworks.

give example on substitutions for frieworks. I would recommend adding more information about how the chemicals in the firecrackers are dangerous for the air. Since I didn't go into full enough details (if you don't you might get marked down for not having enough details or evidence)

Answer:

fisrt one is the answer most likely

Answer:

D

Explanation:

any of a large group of organic compounds occurring in foods and living tissues and including sugars, starch, and cellulose. They contain hydrogen and oxygen in the same ratio as water (2:1) and typically can be broken down to release energy in the animal body.

The characteristic that all protozoans display is their eukaryotic nature. Thus, the correct option for this question is D.

Protozoans may be defined as single-celled microscopic organisms that significantly belong to the kingdom of Protista. These organisms are eukaryotic in nature, and hence they have a true and membrane-bound nucleus in order to function properly.

Some protozoans are definitely attached to the substrate or construct cysts. So, they do not migrate around. But some protozoans have the capability to move around at some stages in their life cycles mostly after the cell division.

So, option B is eliminated. Protozoans are heterotrophic as well. They use organic carbon as a source of energy. So, option A is eliminated.

Therefore, the characteristic that all protozoans display is their eukaryotic nature. Thus, the correct option for this question is D.

Answer:

Houses nasal conchae to enhance turbulence for filtering air. larynx. Prevents food and liquid from entering the rest of the respiratory tract.

Explanation:

Houses nasal conchae to enhance turbulence for filtering air through nasal cavity. Hence, the correct option is A.

It is a large air filled space within the nose and is part of the respiratory system. It is lined by an inner thin layer of moist mucous membrane which helps to humidify and filter the air as it is breathed in.

The nasal cavity is divided into two parts-the right and left nasal cavities, separated by a thin bony wall called septum. It is involved in the sense of smell, as small receptors located in the mucous membrane of the nasal cavity are responsible for detecting different odors.

Overall, the nasal cavity is a crucial part of the respiratory system and plays an important role in protecting the body from inhaled irritants, facilitating the sense of smell. Hence, the correct option is A.

Chlorophyll is the primary pigment that makes leaves green in land plants, by absorbing red and blue light.

It is a pigment present in the plant leaves, through which plant leaves apers green in observation, it plays several roles in the plants other than the green appearance of the leaves.

During photosynthesis, this chlorophyll pigment is responsible to form reaction center through which light is absorbed and leads to a process through which light converts into chemical energy for the synthesis of food.

It is present in the chloroplast, which is the site of photosynthesis, and provides the necessary components for plant food synthesis.

Therefore, the primary pigment that makes leaves green in land plants is known as chlorophyll.

A bacterium has positively supercoiled DNA. This is likely because? A. The bacteria don't normally express their genes. B.

Explanation:

The bacteria normally grow in high temperature condition. So, the correct option is D.

Bacteria are defined as tiny, single-celled organisms that are millions of different types of bacteria. Many can be found in and on the body and are beneficial to us. Bacteria lack a membrane-bound nucleus and other internal structures, so they are classified as unicellular life-forms called prokaryotes.

The bacteria in our bodies help break down the food we eat, provide us with nutrients and neutralize toxins that play an essential role in preventing infection by protecting colonized surfaces from invading pathogens.

Thus, the bacteria normally grow in high temperature condition. So, the correct option is D.

Answer:

Denature

Explanation:

Denature

Answer:

A substance that speeds up a chemical reaction—without being a reactant—is called a catalyst. The catalysts for biochemical reactions that happen in living organisms are called enzymes. Enzymes are usually proteins, though some ribonucleic acid (RNA) molecules act as enzymes too.

ExplanatioEnzymes perform the critical task of lowering a reaction's activation energy—that is, the amount of energy that must be put in for the reaction to begin. Enzymes work by binding to reactant molecules and holding them in such a way that the chemical bond-breaking and bond-forming processes take place more readily.

Reaction coordinate diagram showing the course of a reaction with and without a catalyst. With the catalyst, the activation energy is lower than without. However, the catalyst does not change the ∆G for the reaction.

Active sites and substrate specificity

To catalyze a reaction, an enzyme will grab on (bind) to one or more reactant molecules. These molecules are the enzyme's substrates.

In some reactions, one substrate is broken down into multiple products. In others, two substrates come together to create one larger molecule or to swap pieces. In fact, whatever type of biological reaction you can think of, there is probably an enzyme to speed it up!

The part of the enzyme where the substrate binds is called the active site (since that’s where the catalytic “action” happens

Answer:

Natural selection can cause microevolution (change in allele frequencies).

Explanation:

With fitness-increasing alleles becoming more common in the population.

Fitness can affect the survival and reproduction rates of individuals with different alleles, leading to differential contribution to the next generation and changes in the frequency of these alleles in the population.

Fitness is a measure of the reproductive success of an individual within a population. The fittest individuals are those that are most successful at passing their genes on to the next generation. When the environment changes, the selective pressures on a population also change. This can lead to changes in the relative fitness of different individuals, and thus changes in the allele frequencies of a population over time.

For example, if a population of birds lives on an island with small seeds, those birds with small beaks may be more fit than those with larger beaks. This is because they are better adapted to the environment and can more easily obtain food. Over time, the frequency of the small-beaked allele will increase in the population, while the frequency of the large-beaked allele will decrease.

Thus, fitness can drive changes in the allele frequency of a population over time by favoring those individuals with alleles that are better adapted to the environment.
