d. have the same movement as thermohaline currents
2. A water molecule's shape resembles which of the following?
a. oval
b. circle
c. square
d. triangle
3. Much of the earth's heat is retained in the
a. crust
b. wind
c. oceans
d. mountains
4. Most hurricanes will originate
a. near the North Pole
b. in the equatorial region
c. when the water and air are cold
d. below the ocean's surface current
Option D is correct.
d. have the same movement as thermohaline currents
Explanation:The movement of the surface water of the ocean due to the certain pattern of wind and Coriolis Effect and earth spin creates surface currents. That are influenced by all of the above three except the fourth one.
Answer 2:Option D is correct.
d. triangle
Explanation:Water molecules are not linear in shape. Oxygen has 8 electrons in its valence shell so there are two bonding pairs in water and two lone pairs. Lone pairs strongly repel each and water molecules get bent shape due to this.
Answer 3:Option C is correct.
c. oceans
Explanation:We just do not know that how much heat is captured in the oceans. Most of the heat dissipates in the atmosphere is absorbed in the oceans. So, most of the heat is retained in oceans.
Answer 4:Option B is correct.
b. in the equatorial region
Explanation:Hurricanes begin as the warms storms in tropical regions of due to the warm moist water of Atlantic and Pacific Oceans near the equator. So the correct option is B.
The odd statement is b. exist in large lakes
Explanation:Surface currents are generated largely by wind. Their patterns are determined by wind direction,Earth's rotation, and the position of landforms that interact with them. Currents may also be generated by density differences in water masses caused by temperature and salinity variations but they are not present in the form of lakes
The shape of H2O molecule is oval
Explanation:It is not completely oval but irregular A molecule of water has an angular or bent shape. The H-O-H bond angle in a molecule of water is 104.5o, an angle that is also quite close to the 109.5o bond angles of methane so we can say that it is a little bit oval plus triangular too.
Much of the earth's heat is retained in the oceans
Explanation:Earth retains its temperature in water cycle and we know that water cycle is mostly dependent upon the ocean. Although winds are also responsible but mostly it is retained by oceans. Similarly the constant exchange of energy between the Earth's surface and the greenhouse gases is what enables the planet to maintain its average temperature of 15 degrees Celsius.
Most hurricanes will originate in the equatorial region
Explanation:A hurricane needs the warm water of the tropics, which feeds a storm with energy, in order to form. Most of them are originated in the African continent and that is why we can say that they originate from the equatorial region because much part of Africa lies in equator.
A lens that is thicker in the center than at the edges is called a ____________________ (concave, convex) lens.
convex lens
Explanation:A convex lens is thinner at the edges and thicker towards the center.
It spreads light rays apart producing an image smaller than the actual object. Nearsighted people (people who see close objects fine but distant objects appear blurry) have concave lenses in their glasses to correct their vision.
Convex lens is the right answer since it is thicker in the center while concave is thinner in the center

Nitrogen cycle is important to humans because it converts nitrogen into a form that humans can obtain by eating other organisms.
NITROGEN CYCLE:
Nitrogen cycle involves the manner by which nitrogen is recycled in the environment i.e. from the soil to the atmosphere and vice versa. Nitrogen is fixed by bacteria present in the root nodules of leguminous plants. The plants absorb nitrogen in form of nitrates. Human beings benefit from this process when they feed on organisms like plants that have converted nitrogen to a usable form. Therefore, nitrogen cycle is important to humans because it converts nitrogen into a form that humans can obtain by eating other organisms.Learn more at: https://brainly.com/question/23603107?referrer=searchResults

The nucleus is a structure that surrounds a cell and helps control what enters and exits the cell.
The nucleus is the cell's control center, housing the genetic instructions. Enclosed by a nuclear envelope, it regulates transport of material into and out of the nucleus. However, not all cells contain a nucleus.
Explanation:The nucleus is a crucial component of a cell, often considered its control center because it houses the cell's genetic instructions or DNA. This genetic material determines the entire structure and function of the cell.
The nucleus is enclosed by a double membrane known as the nuclear envelope that assists in regulating the transport of materials, like ions and molecules, in and out of the nucleus through nuclear pores. Inside the nucleus, the semi-solid fluid is known as nucleoplasm, where we find the chromatin and the nucleolus.
Interesting to note, not all cells contain a nucleus. Some cells, such as mammalian red blood cells, do not contain nuclei. In contrast, muscle cells might contain more than one nucleus, a condition known as multinucleated.

Why does
culture establish the standard by which quality of life is measured
Answer:
Culture establishes the framework in which individuls judge their environment.
Explanation:
Quality of life is the concept sorrounding all aspects of a persons life and focus on that person's needs as well as the way they are satisfied in its environment. But there is a bias in it, because while a person living in a country that offers it a lower standard of living can perceive it has the best quality of life without universal healthcare, free access to education, and a big market of employment. That person can believe that it has the best quality of life. Even though are countries with better standard of living. So, quality of life is a subjective cultural construction built by a society perception. That becomes objective and universal when is compared to different countries.

Suppose that you found a vertebrate fossil and brought it to an expert. The expert showed you that the joint structure of the fossil was similar to the joint structure of a modern squirrel. Infer the kinds of movements for which the animal had been adapted. Explain your inferences in a paragraph.
As we know before in back in time. Animals will adapt to their environment that their ancestors didn't have. This animal must have used to have a straight legs but then adapted since it couldn't really move. Then over time it most have started to bend so that way it could move faster. I think that it must have had straight legs because most animals aren't originally the same like humans have tailbones and tails or six fingers. I also feel that it was a analogous structure. Because the squirrel and vertebrate fossil had the similar appearance but are not evolved together and don't have a common ancestor.

Which word identifies the agent that carries the energy released from earthquakes? Epicenter focus lithosphere waves
The correct answer is - waves.
When there's an earthquake, it means that there's a big shock deep inside the ground where a large amount of energy is released, This energy, since it is inside of the Earth, is transferred through the crust in the shape of waves, or rather, seismic waves. The bigger the stress inside the Earth, the more intense the seismic waves, and vice versa, the lesser the stress, the lesser the intensity of the waves. There's special scales that are measuring the frequencies of this waves, and some of the most popular in usage are the Richter scale, and the Mercalli scale.

convolutions
explanation
The convolutions is basically consist of grooves called sulci and raised ridges in between called gyri . A convolution is a curvature of a surface. Picture a fully inflated beach ball. It has no convolutions - it is entirely convex. Now, take out some of the air, and fold the surface of the ball. Each place you make a valley in the surface, you make a convolution
The answer is Convolutions
ExplanationConvolutions are located in the cerebral cortex area of the brain. This area has a wrinkled surface , hence named as Convoluted part or convolution. Convolutions contain ridges and grooves. Deep portions or grooves are called sulci Whereas raised portions or ridges are called gyri. Basically gyri are the specific area of the brain where memories are stored.
In ferns the spores develop on A. the tip of the gametophyte. B. the underside of the gametophyte. C. the roots of the gametophyte. D. the underside of the sporophyte.
Answer:
The correct answer is option D-the underside of the sporophyte.
Explanation:
Ferns are pteridophytes which evolved earlier than the flowering plants. They do not produce seeds and reproduce through spores.
These spores are usually present on the underside of fern leaf also called "fronds" in sporophytic structures called sori. When these spores are ripened they are released from the capsule which germinates to produce prothallus, a gametophyte from which gametes are produced.
Thus, option D-the underside of the sporophyte is the correct option.
