which one of these situations is commonly caused by acid rain?
a. people being poisoned by drinking water
b. fish and birds in freshwater habitats dying off
c. people receiving acid burns on there skin
d. whales and dolphins dying off in the oceans
A situation that is commonly caused by acid rain is the dying off of fish and birds in freshwater habitats. Thus, the correct option for this question is B.
What do you mean by Acid rain?Acid rain may be defined as a type of precipitation that correspondingly include acidic components, like sulfuric acid, nitric acid, etc. that fall to the ground from the atmosphere in wet or dry forms like rain, fog, hail, etc.
The pH of acid rain is generally low compared to normal water. So, it causes numerous impacts on the earth's surface. But the most consequential influence of acid rain is the destruction of fish and birds in freshwater habitats.
It generally lowers the pH of the freshwater ecosystem and makes it unfavorable for many organisms like producers, small fishes, birds, etc. They cannot adapt themselves to such lower pH and have to dye off.
Therefore, the correct option for this question is B.

What is the difference between cytokinesis in plant and animal cells?
Answer:
The primary difference between cytokinesis in plant and animal cells is that cellular reproduction is done sexually (meiosis) in animal cells, while cellular reproduction is done asexually (mitosis) in plant cells.
To better elaborate, Sciencing.com, states, "In plant cells, cytokinesis simply consists of the cell plate forming at the equator of the old cell that will soon be two. The cell plate–the future cell wall that will separate the two cells--divides the cytoplasm in half. . . . Cytokinesis in animal cells is more complex than in plant cells. A contractile ring, underneath the original cell's membrane, begins to form and contracts, which creates the cleavage furrow. The furrow grows deeper between the two cells until they pinch off and separate from one another, resulting in two separate daughter cells."

What is the relationship between global winds and global ocean currents?
A. The pattern of global winds is one of the factors that drives global ocean currents
B. The pattern of global ocean currents is one of the factors that drives global winds.
C. Both are caused by heat from the sun, and they do not affect each other.
D. Both are caused by Earth's rotation, and they do not affect each other
Answer: B
Because i said so
The uneven heating of the Earth's surface leads to the formation of large global wind systems. The surface currents of the oceans are in turn driven by these global wind systems. Thus, option B is correct.
What are global winds and global ocean currents?Large-scale surface ocean currents are propelled by global wind systems that are fuelled by solar energy. These currents transport heat from the tropics to the poles, altering the climate on a local as well as global scale.
Friction from the global winds, which both follow the same basic circulation, clockwise in the Northern Hemisphere and counterclockwise in the Southern Hemisphere.
Warm water and precipitation are transported from the equator to the poles by ocean currents, whereas cold water is returned to the tropics from the poles.
Therefore, The pattern of global ocean currents is one of the factors that drives global winds.

How does carbon move through Earth's spheres in the slow carbon cycle? Be sure to include carbon sinks and sources and the movements between them in your explanation.
Answer:
Respiration is a necessary process conducted by animals and plants in efforts of getting rid of carbon dioxide. When fossil fuels are burned, that is when the carbon moves towards the atmosphere. Carbon enters the atmosphere in forms of carbon dioxide gas when humans burn fossil fuels through processes such as powering factories and driving cars.

Why does a lunar eclipse effect a larger area?
Answer:
A lunar eclipse occurs when the Moon moves into the Earth's shadow. This can occur only when the Sun, Earth, and Moon are exactly or very closely aligned (in syzygy) with Earth between the other two, and only on the night of a full moon. The type and length of a lunar eclipse depend on the Moon's proximity to either node of its orbit.

In an enzymatic reaction: Select one: a. The enzyme leaves the reaction chemically unchanged b. The least important level of organization for an enzyme is its tertiary structure c. Increasing temperature above the optimal value slows the reaction rate
Answer:
c. Increasing temperature above the optimal value slows the reaction rate
Explanation:
Enzyme activity is affected by factors, such as temperature, pH, and concentration.
The rate of an enzyme-catalysed reaction increases as the temperature increases. However, increasing the temperature above the optimal value slows the reaction rate because the enzyme becomes denatured and can no longer function.
Thus, the correct option is "C"
c. Increasing temperature above the optimal value slows the reaction rate
Determine the stimulus, receptor, control center response and effector for gas exchange for plants.
I put slides to help find the answer Please help me!!
Answer:
The exchange of oxygen and carbon dioxide in the leaf (as well as the loss of water vapor in transpiration) occurs through pores called stomata (singular = stoma). Normally stomata open when the light strikes the leaf in the morning and close during the night.
Stomata (the receptors of gas exchange process) are tiny holes found in the underside of leaves. They control water loss and gas exchange by opening and closing. They allow water vapour and oxygen out of the leaf and carbon dioxide into the leaf. In low light the guard cells lose water and become flaccid, causing the stomata to close

Answer:
Honestly i think that its Richness because its good to have a good amount of different species so that there is a good number of animals to create a food chain. The amount of animals in a population is important but its more important to have a variety of different animals so that all the populations have other animals to eat or survive off of.

why does the vagina get wet ?
Answer: From getting turned on
Explanation:
Answer: Hor/mon/es among Other things
Explanation:
Aro. usal; As you become arou. sed, blood flow to your geni. tals increases, which triggers the release of fluid from the cer. vix and the Bar tholin’s glands, which provides lubr. ication during sex. ual activity. Often, the more arou. sed you’re feeling, the more va. ginal lub. rication your body will produce. Horm ones and age; Horm. ones play a big role in va. ginal wet. ness. Higher estro. gen levels lead to increased va. ginal we. tness, but as your body starts to produce less estr. ogen during meno. pause and afterwards, your body may not produce as much va. g inal fluid, making your va gina drier. Meanwhile, as you move through your men. strual cycle and ovul. ation approaches, your cer. vix produces more va. ginal fluid, which plays an important role in helping sp. erm travel to an egg during the process of fer. tilization. Infection; Sometimes you will feel more we. t than usual if you have an infection such as bacterial va. ginosis. The va. ginal fluid helps to remove bacteria from the va. ginal canal. Infections may also lead you to produce other types of va. ginal dis. charge, which will vary in appearance depending on the type of infection. But if you notice any disch. arge that’s an abnormal color or smell, you’ll want to get in touch with your physician. Medication; Horm. onal birth control can alter your va. ginal fluid production, leaving you more w.et or dry than you’re used to when not taking the medication.
