Answer:

destruction of natural habitats

Explanation:

First let's define our main terms or each answer choice.

1)Decreased deforestation - Deforestation is the action of clearing mass amounts of trees for human use such as farms, buildings, houses etc. So this answer is basically saying that as the human population increased the amount of trees that get destroyed will decrease.

2)Destruction of natural habitats - Natural habitats is simply the natural home of animals. So this answer is saying as the human population increases the more number of animals natural homes will be destroyed

3)Unchanged climate - Climate is basically the long term weather of an area. So this answer choice is saying that as the human population increases the climate will remain unchanged.

4)Increased biodiversity - Biodiversity is the different kind of life on earth usually regarding a specific habitat or ecosystem. So this answer choice is essentially saying that as the human population increases the types of life on earth increases.

What comes with increased human population?

As the human population increases the need for food, houses, water, jobs etc increases as well. Keep that in mind while looking at the answer choices.

Determining the answer

Why the answer isn't A

Rereading 1) and then what comes with increased human population we can most definitely rule out A. As human population increases the need for houses and jobs increases. In order to have a good enough supply of wood and land for these houses and buildings for these jobs, deforestation must occur. So as human population increases deforestation would increase as well.

Why the answer is B.

Rereading 2) and then looking at what comes with increased human population we can maybe say that B is correct. Looking back at the previous section we've already identified that mass deforestation must occur to satisfy the needs for wood and land for houses and jobs for the increased population. As we know many animals probably live in these forests and inside of the trees so many of these animals homes would be destroyed resulting in the destruction of natural habitats ( animals homes )

Why the answer isn't C

After rereading section 3) and what comes with increased human population we can rule out C. If an increase in human population results in deforestation the amount of CO2 released into the air increases as well. If you didn't know trees absorb CO2 which is bad for the atmosphere. Once destroyed the trees release the CO2 that they have absorbed. CO2 and other green house gases create holes in our atmosphere leading to a change in climate as the suns radiation travels through these little holes. This results in a change in temperature, increased natural disasters and the melting of ice on the poles which also leads to increased temperatures. Deforestation isn't the only cause of this ( gasoline from cars, burning of fossil fuels , pesticides and many other human caused actions result in this ). These are all human caused things so if the human population increases the amount of green house gase emissions would likely increase as well meaning the climate would no remain unchanged.

Why the answer isn't D

After reading section 4) as well as the section titled "why the answer is B" we can rule out D. In order for an increase in biodiversity to occur, natural habitats must be preserved ( remain untouched ) if deforestation occurs then natural habitats will be destroyed and biodiversity will never increase as many animals may not be able to find another sustainable habitat. Not only that but the question asks about a negative affect and biodiversity is a good thing.

CRISPR/Cas9 is the most widely used genome editor.

Explanation:

Over time, all of the finches adapted to their food source. This caused the evolution of their beaks to begin.

The highlighted part in the below diagram of the male reproductive system is Epididymus. The correct option is D.

The highlighted part in the reproductive system is the epididymis, it is located with vas deferens in close proximity to each other and are involved in the transport and storage of sperm.

The urethra and seminal vesicles are also important components of the male reproductive system, but they are not typically highlighted in diagrams or illustrations of the reproductive system.

Each testis has a little, tightly coiled tube linked to it (the male sex glands that produce sperm). Male reproductive cells known as sperm travel from the testicles into the epididymis, where they mature and are then stored.

Therefore, the correct option is D.

Plant development from vegetative components such as stems, roots, and leaves is known as vegetative propagation.

Plants, unlike most animals, may be propagated by extracting a portion of tissue (usually a leaf, stem, or root) from a parent plant and cultivating it in perfect conditions. Remove a little growing tip off an apple tree limb and plant it in moist soil in a warm, semi-humid region, for example. It will become a new plant when the branch grows roots.

Reasons for vegetative propagation:

The downside:

VEGETATIVE PROPAGATION -:

PROPAGATION IS THE MODE OF REPRODUCTION IN WHICH PRODUCTION OF NEW PLAN TAKE PLACE FROM THE VEGETATIVE PART OF ROOTS STEM LEAVES BULBILIS OF PLANT .

NATURAL METHODS -:

1 PROPAGATION BY ROOTS

The missing element that is needed to make collagen in cellulose is  vitamin C, zinc, copper and manganese to make the triple helix.

Glycine, proline, and hydroxyproline are the three amino acids that make up collagen.

Cellulose synthesis is gaining popularity not only because cellulose is a major component of plant cell walls, but also because it has the potential to become a major resource for renewable biofuels.

The cellulose structure is made up of long polymer chains of glucose units connected by a beta acetal linkage.

The image on the left depicts a very small section of a cellulose chain. The monomer units are all beta-D-glucose.

Amino acids are the building blocks of proteins. These amino acids form protein fibrils with a triple helix structure.

To form the triple helix, your body also requires adequate amounts of vitamin C, zinc, copper, and manganese.

Thus, the missing elements are vitamin C, zinc, copper and manganese.

Efficient milk production is a benefit of commercial agriculture. thus option B is correct.

Commercial farming is a practice where crops and livestock are cultivated with the intention of selling them as finished goods to gain money. A significant amount of capital investment is required to grow commercial farming.

When making commercial dairy, the milk is placed into MASSIVE industrial centrifuges, where it is divided into different components like lipids and proteins. To create whole, low-fat, and skim milk, the components are then once again mixed. It is pasteurized, put in a bottle, and transported.

The ozone layer is best described as a layer of the atmosphere, rich in ozone gas, that protects the Earth's inhabitants from the harmful effects of UV radiation. The correct option is C.

The ozone layer is found in the stratosphere, a region of the Earth's atmosphere located approximately 10 to 50 kilometers above the Earth's surface.

It contains a higher concentration of ozone (O3) molecules compared to other parts of the atmosphere.

The ozone molecules in this layer absorb a significant portion of the incoming UV radiation from the Sun, thereby shielding living organisms on Earth from its harmful effects.

UV radiation can be harmful to human health and ecosystems.

Overexposure to UV radiation can cause sunburn, skin cancer, cataracts, and immune system suppression in humans.

Thus, the correct option is C.

Natural selection is the process by which organisms with favorable features and characteristics that enable them to adapt to their environment survive while those with unfavorable traits die off.

In a changing environment, it will be observed that the organisms with the most favorable traits will be the most dominant in the environment.

Therefore, for the Year 5 and Year 10, the most likely trend that will occur is that the organisms with harmful characteristics will be decreasing in the plant population while organisms with neutral or beneficial traits will likely be increasing in number.
