hi <3
the correct option would be C.8
a pH above 7 is considered 'basic' and the higher the pH above 7, the more 'basic' it is
therefore, a weak basic solution would have a pH of 8
hope this helps :)

hope it is helpful to you ❤️Of the thorns or spines and the greeny pigmented hard part of the cactus are the leaves and why?
The spines of a cactus are exactly not the leaves, but they are the solid hard part that reduces the rate of transpiration, so as to level the water constant in the cactus' body. They are important as it can reduce the animals from eating the cactus.
However, camels have thick jaws and can eat cactus easily .

Which states would be the most likely to experience the next volcanic eruption AND earthquake in the United States? List at least 3 for each hazard and explain why they might happen there.
Answer:
AlaskaWashingtonHawaiiCaliforniaOregonExplanation:
Eruptions along the western edge of the United States have formed the Cascades volcanic mountain range. Also, they develop island chains, such as the Aleutians in Alaska, which makes Alaska a potential volcanic eruption place. A prominent example of an eruption along the Ring of Fire was the dramatic eruption of Mount Saint Helens in Washington in 1980, which makes Washington a potential volcanic eruption state. Deep beneath Hawaii, there is a fixed source of abundant rising magma, called a hot spot, making Hawaii likely to be a volcanic eruption state. In 2018, they added Salton Buttes to the 2018 assessment, which is a high threat of a volcanic eruption. In other words, California is likely to be a volcanic eruption state. Eleven of the eighteen very high threat volcanoes are in Oregon, and few other states, where explosive and often snow- and ice-covered volcanoes can project dangerous long distances to densely populated and highly advanced areas.
How are globes used?
Answer:
Globes are used to look at places, without a device. You can think of a globe as a map of the world wrapped up into a ball. If you wanted to look at the United States, you could twist the globe, and see it, and surrounding places like Canada or South America.
In a different case, they are used for school geography. The students are asked to find a place and point to it on the globe.

blank makes up cell membranes
Phospholipids : This makes up the bi-layer which is the membrane's basic structure and has great control over what can enter and exit the cell, due to their hydrophobic tails and hydrophilic heads.
Cholesterol : This also controls entry and exit of substances as it also exhibits hydrophilic heads and hydrophobic tails. It also stabilises the membrane and affects its fluidity (the more there is, the more fluid is the membrane.)
Glycolipids : Those can act as receptor molecules (essential for cell-signalling), antigens and in cell-adhesion
Answer:
glycerophospholipids
Explanation:
With few exceptions, cellular membranes — including plasma membranes and internal membranes — are made of glycerophospholipids, molecules composed of glycerol, a phosphate group, and two fatty acid chains.

Number the steps of Darwin's theory in order.
Answer:
1.Natural Selection
2.Overproduction
3.Variation
4.Struggle for existence
The steps in the theory of Darwin should be performed in the following order: Overproduction, Natural Selection, Variation, and the Fight for Existence.
Thus, the following sequence can be used to number the steps in Darwin's theory, which involves variation where people within a population display innate variances in their attributes. This step is followed by overproduction, when an organism produces more children than the environment can sustain, resource competition results.
People within a population battle for survival because of overproduction and a lack of resources. The last step is natural selection, which involves people having advantageous mutations that suit their environment better have a higher likelihood of surviving and reproducing successfully.

Why would bacteria, plant and animal cells need to be different?
Answer:
Because each the cells would have different functions on different organisms.
Explanation:
Bacteria cells are usually prokaryotic which means that it is only composed of one cell. The single cell already has everything it needs so therefore, it isn't as complex as plant and animal cells.
Plants are autotrophs and produce their own food through photosynthesis. Plant cells would have a large vacuole, cell wall, chloroplasts, unlike animal cells.
Animal cells have all the cell organs that plant cells except a large vacuole, cell wall, and chloroplasts. Animal cells also have lysosomes in which plant cells don't.
What do barycenter, nutation , and precession have in common ?
Answer:
Precession: The slow movement of the axis of a spinning body around another axis due to a torque, such as gravitational influence, acting to change the direction of the first axis.
Barycenter: The center of gravity between two objects
Nutation: As an object precesses, it will not precess in a circular path, but will wobble/ oscillate slightly. This wobble is nutation, the periodic movement of an axis due to gravitational interactions with other bodies.
These are all caused by gravitational interactions between two or more bodies.

how could you increase the rate of the reaction in part C of the above image? select the best response based on the information given
a. expose the reaction to sunlight
b. decrease the amount of reactiant(s)
c. change the temperature
d. increase the amount of enzymes
Answer:
c) change the temperatureTo increase the rate of the reaction in part C of the above image, change the temperature. Thus option C is correct.
what are the factor affecting the rate of reaction ?
At higher concentration of reactants, more collisions leads to increase the rate of the reaction.
Changing the pressure can change the concentration leads to high number of collisions caused increases the reaction rate.
If a reactant is a solid and grinding of these reactants can increase the surface area, will lead to faster the reaction.
Increase in temperature, means molecule have higher average kinetic energy and more collision causes an increase in the reaction rate.
The medium in which the reaction occurs is another factor like in aqueous solution the reaction go faster.
Catalysts lower the activation energy followed by increase the rate of a chemical reaction.
Thus option C is correct.

THREE catastrophic results of radiation on the Environment
Answer:
adverse effect on human and enviroment.
Explanation:
UV radiation generates ground-level ozone (o3) and dome particulate matter( PM frequently called aerosol ) that include nitrate, silfate and organic aerosols causing adverse effects on humans and the environment. UV promotes the formation of hydroxyl radicals that act as cleaning agents for the troposphere.
Three catastrophic results of radiation on the environment are :
Generation of ground level ozone ( O₃) which degrades the environmentFormation of organic Aerosol which poses health threat to humansFormation of hydroxyl radicals which affects the troposphere.The results of heavy UV radiation on the environment can lead to the degradation of the environment and pose a significant health threat to Humans as well in the environment. some of the results of radiation includes the formation of organic Aerosol which can pose health threat ( Lung diseases ) to humans. while hydroxyl radicals acting as cleaning agents in the troposphere damages the atmosphere as well.

It is vital that organisms maintain their body temperatures. Please use the chart below to pick the best description of what might be occurring based upon the displayed data.
1. The organism is not successfully maintaining their body temperature
2. The organism is trying to get their body temperature under control and will even out soon
3. The organism is maintaining homeostasis so that every time their body temperature starts to drop their brain will send signals to increase it and vice-versa
Answer:
number 3 would be the right answer
Explanation:
The best description would be that the organism is maintaining homeostasis so that every time its body temperature starts to drop, its brain will send signals to increase it and vice versa. So the correct option is A.
What is homeostasis?A self-regulating process, by maintains the stability of the biological organisms while they are trying to adjust to the conditions that are important for their survival is called homeostasis. The individual is able to live only if homeostasis is successful. If homeostasis is unsuccessful the individual will not survive.
The stability that is achieved during the process of homeostasis is actually not permanent. It is a dynamic state of equilibrium. In this condition, continuous changes are happening which ultimately lead to uniform conditions.
A biological system in dynamic state equilibrium will always tend to attain a steady state equilibrium. This is a balanced condition to resist any kind of outside forces of change.
Therefore the correct option is A.
