Answer:
B. Dependent variable.
Explanation:
An experiment can be defined as an investigation which typically involves the process of manipulating an independent variable (the cause) in order to be able to determine or measure the dependent variable (the effect).
Hence, an experiment is used by scientists or psychologists to illustrate how a change in variable affects behavior.
This ultimately implies that, an experiment can be used by scientists to show or demonstrate how a condition causes or gives rise to another i.e cause and effect, influence, behavior, etc in a sample.
In an experiment, there are two (2) main types of variables and these are;
I. Independent variable: this is the variable that is being manipulated or alters and as such it is the cause of a behavior. This variable stands alone.
II. Dependent variable: this variable is the direct effect of the actions of the researcher in an experiment.
Basically, the dependent variable is the variable that is being measured and tested by an experimentalist.
Hence, dependent variable is another term for the responding variable because it responds to an action.
what vibrates as an electromagnetic wave passes by?
how is the hydrosphere connected to the lithosphere
Answer:
Water in the lake (hydrosphere) seeps into the cliff walls behind the dam, becoming groundwater (lithosphere), or evaporating into the air (atmosphere). Humans (biosphere) harness energy from the water (hydrosphere) by having it spin turbines (lithosphere) to produce electricity.

The six modes of disease transmission shown in the Model 2 are
1. Airborne
What is airborne?The Airborne transmission can be caused by coughing, sneezing where
water droplets carry the disease causing organisms.
Example: flu, tuberculosis, etc.,
2. Food borne or waterborne
The pathogen is transmitted by the consumption of contaminated
food or water
Eg: cholera, botunilsm, etc.,
3. Vector
The vector such as insects or animals can act as vectors by carrying disease causing malaria, dengue.
4. Blood borne
The disease is caused by the transmission of blood or contact of
injured cuts or incisions.
Example: hepatitis, AIDS, etc
5. Contact
The disease is caused by the person to person direct contact of skin to skin such as leprosy, skin and eye infections, fungal infections, etc.,
6. Seˣual
The disease is seˣually transmitted are AIDS, gonorrhea, syphilis.

if the skeletal muscle cells in your leg are performing lactic acid fermentation to produce the necessary ATP for their proper functioning, decribe what is happening to the O2 gas you are breathing
Answer:
The O2 gas in uses in Aerobic Respiration and That O2 is performing that process to make ATP for your body and making glucose to function your body
Explanation:
Lactic Acid Fermentation is Anaerobic Respiration which doesn't Involve Oxygen

Discuss how algae help support other life on earth?
Answer:
In the distant past, algae helped turn the earth's then inhospitable atmosphere into one that could support modern life through photosynthesis, which plants use to turn carbon dioxide and sunlight into sugars and oxygen. Some of the algae sank to sea or lake beds and slowly became oil.
describe in detail Alfred Wegener's idea of continental drift
HELPP
Answer:
Continental drift was a theory that explained how continents shift position on Earth's surface. Set forth in 1912 by Alfred Wegener, a geophysicist and meteorologist, continental drift also explained why look-alike animal and plant fossils, and similar rock formations, are found on different continents.
Explanation:
An athlete throws the javelin 212 m. The average speed of the javelin was 15 m/s. How long was the javelin in the air?
Answer:
The correct answer is - 14.133 seconds.
Explanation:
The time that the javelin took in the air before landing after the 212 m throw can be calculated by simple distance and velocity formulas which say that the speed of an object is equal to the distance traveled by the object in unit time.
Given:
Speed or s = 15 m/s
Distance or d = 212 m
Then, the time or t =?
Solution:
By the formula, s = d/t
or t = d/s
t = 212/15
t = 14.1333
thus, the correct answer is - javelin was in the air for 14.1333 seconds.

Pesticides often do not just kill the target pest but also poison
inects in and
around the fields. These insects with the pesticides can be eaten by other animals and poison them.
Some pesticides are suspected of disrupting the
of wildlife and people. These
chemicals
because they are fat soluble and get passed up the food chain
by
Unlike pesticides, fertilizers are not directly toxic but their presence in
freshwater and marine areas alters the
system, and in consequence the species
composition of specific ecosystems. Their most dramatic effect is
resulting in an
explosive growth of algae due to
nutrients. This depletes the water of dissolved
oxygen, which in turn can kill fish and other aquatic life.
Answer:
Other problems of pesticide use include most pesticides kill beneficial species as well as the target pest species, pesticides do not stay put, pesticides harm wildlife, and pesticides can threaten human health. Farmers pay more and more for a pest control program that often becomes less and less effective.

Yellowstone is located above a blank the collapse of a crater after volcanic eruption
Answer:
Starting near the Oregon/Nevada/Idaho juncture 16 million years ago, a line of rhyolite magma centers—supervolcanoes—formed across what is now the Snake River Plain of southern Idaho. Yellowstone National Park today lies directly over the hotspot.
Those parts of the surrounding states of Montana, Idaho, and Wyoming that are closest to Yellowstone would be affected by pyroclastic flows, while other places in the United States would be impacted by falling ash (the amount of ash would decrease with distance from the eruption site).
Answer:
Caldera
Explanation:
Yellowstone is located above a caldera.

Look at the species name for each alien. How do you think these names were chosen?
plz answer
Complete question:
You will find the complete question in the attached files
Answer:
1)
Alienus quadlegicus: Mouth opened and no armsAlienus hairicus: Mouth opened, hairyAlienus tritoothicus: Mouth opened, not hairyAlienus stripicus: Mouth not opened, hornsAlienus bloblicus: Mouth not opened, No legsAlienus fuzzicus: Mouth not opened, Legs2) Genus Alienus
3) Morphological characteristics of aliens are used to identify them and to name them.
Explanation:
1) The dichotomous keys give you information about the groups that are being differentiated to correctly identify them. All you need to do is follow the description of the organisms and the numbers where each description drives you. If you observed correctly the organism, you will reach the scientific name, or genus, or any other taxonomic group you are looking for.
2) Taxonomy is the study of different organisms, their classification into categories according to their morphological and molecular characteristics and their evolutionary relationships. A binomial name is assigned to each organism, composed of a genus and the epithet.
Among all the categories where organisms are classified, we can find the genus, which includes many species that share some common characteristics that are used to group them together.
In this example, Alienus is the genus of all these aliens species.
3) Morphological characteristics of aliens are used to identify them and to name them.
Alienus quadlegicus: Four-legged alienAlienus hairicus: Hairy alien.Alienus tritoothicus: Alien with three teethAlienus stripicus: Alien with striped hornsAlienus bloblicus: Alien with no shape. Shapeless massAlienus fuzzicus: Short fine-haired alien.

Answer: A.
Explanation:
Palisade mesophyll cells contain the most amount of chloroplasts with an average of 30–70 chloroplasts per cell so they will be number 2 in the graph.
Spongy mesophyll cells contain less chloroplasts than their palisade counterparts to enable them have a larger surface area for gas diffusion.
The guard cells have the least amount of chloroplasts on average and so will be number 1. on the graph.

wastes
water
Answer: water, and oxygen
Explanation: Homeostasis depends on maintaining correct fluid levels within the cell and on exchanging useable materials, such as oxygen, for waste products, such as carbon dioxide. Plasma membranes allow water, oxygen and carbon dioxide to pass through by osmosis, or passive diffusion.
What else do you think plants may need to grow and go through their normal processes?
Plants need water, oxygen, soil, and solar energy.
Those are the only things that I believe plants need. They need water for food and Solar Energy (basically Vitamin D which you get from the sun) and soil to grow. Obviously they need oxygen to be able to survive.
