Answer:
B. Knowledge of growth rates allows researchers to predict responses to changing conditions.
Explanation:
Genetic analyzes are tests that try to identify the genetic composition of a living being, being able to analyze the DNA in a profound way and obtaining crucial information about the organism. The most common way to carry out a genetic analysis is through the sequencing of genes, since they are segments of DNA molecules. Therefore, we can conclude that among all the response options presented above, all that refer to the sequencing of genes should be discarded. Thus, we can see that option B is the correct option, since the analysis of growth rates does not involve a genetic analysis.

1. Would the pollution problems caused by cars and trucks be completely solved if they all became electrically powered overnight?
2. Name one challenge we need to overcome by using solar panels
Answer:
1.This doesn't help COMPLETELY get rid of pollution. It might help lessen the pollution, but it definitely won't solve it, because there are also other things that cause pollution.
2.The main problem with solar power that has stifled its use is the fact that energy production only takes place when the sun is shining. And it won't be beneficial to the countries that aren't really close to the equator ( the middle east) and that might be a problem cause there just might not be enough energy/electricity.

Some ocean plants, such as photosynthetic algae, benefit when dissolved CO2 levels in ocean water are elevated. Complete the
chemical equation by dragging and dropping components of the equation into the boxes that BEST explains how algae use CO2 for
photosynthesis
Answer:
CO2 + H2O ---SUNLIGHT--------> C6H12O6 + O2
Explanation:
In the process of photosynthesis, carbondioxide reacts with water molecules in the presence of sunlight forming glucose molecules and oxygen gas. The carbondioxide enters the plant body through small openings called stomata, these stomata opens when there is sunlight whereas water enters the plant body through roots from the soil and reaches to the leaves. In leaves both combine produces glucose which can be stored in different parts of the body and some oxygen is used by the plants in the process of respiration and extra is released through stomata.
Which role do ultrafine particles play in dirty air?
They contribute to less than 13,000 premature deaths a year.
They can worsen symptoms for people with breathing difficulties.
They are easily removed from the air when people see them floating.
They are constantly filtered by the nose, which prevents lung absorption
Answer:
B
Explanation:
The role the ultrafine particles play in dirty air is that they can worsen symptoms for people with breathing difficulties. The correct answer is b).
What are ultrafine particles?The term "ultrafine particles" (UFPs) refers to particles with a dimension of less than micrometers and more than 0.1 micrometres (100 nanometers), also known as nanoscale particles. The majority of the ultrafine particles are found on motorways and are mostly produced by vehicle emissions.
It has been demonstrated that ultrafine pollution particles may play a crucial role in igniting extra pathways or inflammation, which worsens asthma disease. The ultrafine particles released by motor vehicles and other sources of combustion are covered with an organic chemical coating that can be inhaled.
By oxidizing cells and tissues, these substances create free oxygen radicals that activate the immune system in the lung. For those who have asthma, oxidation exacerbates the allergic inflammation in their lungs.
Therefore the correct option is b).

Match the type of metamorphism to its cause. Impact ? Heat Contact ? Directed pressure Dynamic ? Meteorite Regional ? Surrounding pressure SUBMIT
Answer:
Contact Metamorphism - Heat
The heat is the main cause, cooling magma affects the rock adjacent to an intrusive body.
Dynamic Metamorphism - directed pressure
It takes place due to grinding two large blocks of rock in a fault zone which causes a directed pressure that leads to heat and the formation of these metamorphisms.
Regional - surrounding pressure
A heat and lithostatic pressure come from depth within the earth.
Impact - Meteorite
By collision of meteorite to earth very high amount of kinetic energy is converted instantaneously to heat and differential stress.

A. All of the layers should contain fossils of simple organisms.
B. All of the layers should contain fossils of complex organisms.
C. The lower layers should contain fossils of more complex organisms.
D. The upper layers should contain fossils of more complex organisms.
Answer:
D the upper layers
Explanation:
at first, lifeforms were simple. they got more complex for a variety of reasons, including to adapt to the changing earth. simple organisms will be lower down for that reason.
The lower layers should contain fossils of more complex organisms. So, the correct option is (C).
What are Fossils?A fossil is defined as the preserved remains, imprint or trace of something that once lived from a previous geological era. Examples of fossils are bones, shells, exoskeletons, fossilized traces of animals or microbes, objects preserved in amber, hair, petrified wood, and DNA residues. The totality of fossils is known as the fossil record.
There are four main types of fossils which are formed in different way are conducive to preserving different types of organisms. Fossils are mold fossils, cast fossils, trace fossils and true form fossils.
Fossil layers are fossils that formed in sedimentary rock that formed in layers by depositing and pressing sediments on top of each other.

Select an organism of your interest! Research to see if that organism undergoes asexual or sexual reproduction. Describe why that type of reproduction is advantageous for your organism.
Answer:
Many fungi and plants reproduce asexually. Some plants have specialized structures for reproduction via fragmentation.
Explanation:
This allows them to adjust to conditions in the environment. They can spread quickly through asexual reproduction when conditions are stable. They can increase their genetic variation through sexual reproduction when conditions are changing and variation may help them survive.
Reproduction is a method by which the genetic material from the parent is transferred to offspring and in this way the character and traits are passed from generations.
I will select plants for my research purpose.
Plants are species that reproduce sexually. They have male and female organs that produce cells for reproductions. They sexually reproduce through the process of pollination.
This method of reproduction helps in genetic variation and in forming recombinant species that are more variant.
This variation helps the plant species to survive better compared to less competent species.
Sexual reproduction is beneficial for plants as it increases varieties and helps plants in fighting against a common population disease.
