8. The graph below shows the reaction rates of two different reactions. Which of the following statements could explain the difference in the two reactions?
Answer:
These two reactions have different reactants, bonding and catalysts.
Explanation:
The two reactions are different from one another due to fusion of different reactants as well as different products. These two reactions may have different types bonding i.e. covalent, ionic or metallic bond etc between their atoms. In these two reactions, different types of catalyst are used which helps in speedup the chemical reaction so we can conclude that these two reactions have different reactants, bonding and catalysts in their chemical reaction.

Special cells in the body are responsible for gathering information about the body's environment. These cells are called receptor cells. The information gathered by receptor cells is encoded as electrical signals that travel along the body's nerve cells. The brain and spinal cord then process the electrical signals to determine how the body should respond.
Suppose information gathered by a group of receptor cells has just been processed by the nervous system. Which of the following could happen next?
Answer:
A reflex action

Beginning around 1750,the global human population began to grow at much faster then it had in the years before this time.What caused this to change in the population growth rate?
Answer:
The cartogram is made up of squares, each of which represents half a million people of a country’s population. The 11.5 million Belgians are represented by 23 squares; the 49.5 million Colombians are represented by 99 squares; the 1.415 billion people in China are represented by 2830 squares; and the entire world population of 7.633 billion people in 2018 is represented by the total sum of 15,266 squares. It started in 1798, to the 1800. This period is when the human population began to grow at a faster rate then any other time in history. The answer is 300 years ago.
Explanation : Births - usually measured using the birth rate (number of live births per 1,000 of the population per year). Deaths - usually measured using the death rate (number of deaths per 1,000 of the population per year). Migration - the movement of people in and out of an area.

Answer:
As during the civil war, African elephants with tusks were targeted, and the tuskless elephants were left alone. This, in turn, allowed for the tuskless elephant populace to thrive and continuously grow, while the tusked elephants saw a decline as more and more were poached. So, it is only natural that as time progresses, and assuming the circumstances remain constant, that the tusked elephant population will see a negative trend, and inversely the tuskless elephant population will see a positive trend.
You are looking under a microscope at a dividing cell. You notice
the chromatin has just condensed into chromosomes, the nuclear
membrane has started to break down and the spindle has started
forming. What phase is the cell in?
Answer:
Prophase.
Explanation:
Prophase is the phase of mitosis in which chromatin condenses into chromosomes, the nuclear membrane is started to break down and the forming of spindle has started . Prophase is the first stage of mitosis which occurs after G2 portion of interphase. After prophase, metaphase, anaphase, and telophase occurs that completes the cell division process and the one parent cell divides into two daughter cells.

A. in planets and natural satellites
B. in comets and asteroids
C. in dark matter and dark energy
D. in interstellar gases and stars
Most of the baryonic matter (ordinary matter) of the universe are found in
planets and natural satellites.
The baryonic matter is composed of particles present in the nucleus such as
the proton and neutron . Electrons or other sub-particles aren't present in
the baryonic matter.
This type of matter is present in stars with a percentage of about 10 percent
and in planets and satellites with a higher percentage.

What is the difference between primary and secondary succession? Give an example of each.
Answer:
Some examples of primary succession include the formation of a new ecosystem after a volcano, glacier outbursts, or a nuclear explosion. Some examples of secondary succession include succession after a fire, harvesting, logging, or abandonment of land, or the renewal after a disease outbreak.

Cheests as a species of cat best known for being the fastest land animal, with the ability to sprint at speeds of up to 120
Kilometers per hour, Cheetahs have small heads, lean bodies, long legs, and a yellowish-tan coat with distinctive black spots
Cheetahs face extinction pressure from climate change, hunting by humans, and habitat destruction, which is reducing the size of
their populations, Predict how these pressures have affected the genetic diversity of cheetahs.
Answer:
Genetic diversity has decreased due to inbreeding due to dwindling population size.
Cheetahs are facing great pressures, such as climate change, destruction of their habitat, and also hunting by humans that have greatly impacted their genetic diversity.
What are the causes of inbreeding in Cheetahs?Cheetahs have experienced a very declining rate of their populations due to destruction of their habitat, and also hunting by humans that has resulted in inbreeding in their populations and loss of genetic diversity.
Due to inbreeding, cheetahs have become more exposed to genetic disorders and vulnerable to diseases, and other threats.
Climate change has also posed a great threat to the declining population of cheetahs as it has affected their habitats and food resources. Climate change causes alteration in the temperature and rainfall pattern resulting in low availability of prey and water resources. Therefore, climate change leads to the malnutrition of cheetahs and making them more susceptible to severe disease.
Therefore, cheetahs are facing extinction due to climate change, habitat destruction, and hunting by humans.

Why do we classify lionfish populations near the eastern United States as an invasive species? What suggests that these new populations are not an expansion of the lionfish’s natural range? View Available Hint(s) Why do we classify lionfish populations near the eastern United States as an invasive species? What suggests that these new populations are not an expansion of the lionfish’s natural range? Lionfish are native to the tropical Pacific. There are no natural water routes of warm water between the Pacific and Atlantic oceans.
Answer:
Lionfish is introduced in this region.
Explanation:
The lionfish populations near the eastern United States is considered as an invasive species because this fish is not native species of this region and they were introduced into this region. Due to no predator available for this lionfish will make it invasive species that eliminated the local fish species and disturb the ecosystem. Lionfish are native to the tropical Pacific and there are no natural water routes of warm water between the Pacific and Atlantic oceans which helps this lionfish to reach eastern United States so we can say that it was introduced by humans.
Vascular resistance is due to friction between blood and the walls of the blood vessel. Which of the following causes low vascular resistance?
obesity
dehydration
high blood pressure
cholesterol levels within normal range
Answer:
Cholesterol levels within normal range
Explanation:
Vascular resistance is due to friction between the blood and the walls of the blood vessel, and cholesterol levels within the normal range can cause low vascular resistance, which is the last option.
What is vascular resistance?Vascular resistance is the resistance to blood flow in the blood vessels, which is determined by the diameter of the blood vessels, blood viscosity, and the length of the blood vessels, so when blood flows through the blood vessels, it experiences frictional forces due to the interaction between the blood and the walls of the blood vessels, obesity, dehydration, and high blood pressure can all contribute to increased vascular resistance.
Hence, the correct answer is that cholesterol levels within the normal range can cause low vascular resistance, which is the last option.
