What belongs there in the box

Answer:

Explanation:

Most organisms are adapted to live within a particular range of temperatures and will not survive at temperatures too far above or below their range. Precipitation limits the organisms that can be found in a biome because all organisms need water, and the bigger the animal, the more water it needs.

Our crops depend on insect pollination and the complex biological processes that create soil. We benefit from parks, natural environments, and animals when we do so because it improves our health and wellbeing.

As a society, we rely on healthy ecosystems for a number of purposes, such as crop pollination to ensure that we won't go hungry, air purification so that we can breathe easily, carbon sequestration to control the climate, nutrient cycling so that we can access clean drinking water without having to invest in pricey infrastructure, and so on.

Healthy ecosystems keep our soil in good condition, purify the air, regulate the climate, recycle nutrients, and provide us with food.

Answer:

The correct answer would be - two bands ( one intermediate, and one light)- the light band contains more DNA molecules.

Explanation:

After the switching to the lighter isotope by the second round of replication where light strands are used as template strands, produces the light band of 14N.

After three rounds of semiconservative replication, where template strand contains both heavy and new formed light bands or nitrogen and produces so in a Density gradient, there will be 2 bands one light band and the other intermediate band.

Answer:

A. Plants will only flower during long day periods when the day length exceeds their necessary photoperiod

Explanation:

Photoperiodism is a phenomenon that refers to the response of an organism to the length of day. This phenomenon causes a physiological change in the organisms involved (plants or animals). However, the best studied example of change caused by photoperiodism is that of FLOWERING IN PLANTS.

Different plants flower at different times in response to the day length. Certain plants called LONG DAY PLANTS e.g. spinach and potato etc only flower when the length of day exceeds their photoperiod (threshold), which is usually 12 hours. These plants require very short periods of darkness to flower.

Hence, according to the question, FLOWERING response in plants is the best explanation to describe photoperiodism.

Answer:

Both ferns and flowering plants produce spores at some point in their life cycles. True

Only ferns have a gametophyte as part of their life cycle. False.

Only flowering plants produce pollen grains. true

Both a tree and a large fern plant are diploid sporophytes. True

Explanation:

Yes, both ferns and flowering plants produce spores in their life cycles. In fern plant, it produce spores on the underside of the leaves whereas in flowering plant, there are two types of spores such as microspores and megaspores. Both ferns and flowering plants have gametophyte as part of their life cycle. Flowering plants produce pollen grains whereas non-flowering plants produce spores to continue their generation. Both tree and large fern plants having diploid sporophytes which is a necessary part of their life cycle.

Answer:

a, b, d (see below)

Explanation:

So, looking at the 3 states of matter:

Solid - holds a shape and is made up of particles that vibrate in place (because particles are always moving no matter what)

Liquid - holds shape of its container and has particles with some space in between them that allow them to flow

Gas - holds shape of its container and has particles with huge gaps of space between them that are always, constantly moving and zooming around

Refer to the image below for a better visual understanding.

So, now, looking at the answer choices:

a) moving randomly

Yes. They are—they're speeding around super fast all the time.

Every time heat is added to something, the particles start loosening up and moving. A lot.

So when you add heat to a solid, it starts loosening up and moving around until it becomes flowy enough to be a liquid. Then, if more heat is added, the particles moving faster and loosen up even more until they're a gas.

Imagine doing that one more time, and you'll have plasma. As you may have guessed it, plasma moves super fast

b) collide into each other

Yes. Because they're moving so fast and uncontrollably all the time, they're bound to have rammed into one another a few or more times.

Imagine bumper cars at a carnival, except the speed of each car is sooo fast that you could be on a highway. You're probably going to hit someone, which is why bumper cars are not that fast in reality. For safety reasons.

c) move slow

No. Since we know that they're always zooming around (refer to my bumper car example above, in bold), they obviously can't be slow.

d) high kinetic energy

Yes. Anything moving (a.k.a. in motion) has kinetic energy. If gases zoom super fast 24/7, they will have high kinetic energy.

Having high kinetic energy means that the something is moving really fast or a lot. In this case, gases are both.

e) moving orderly

No. They're moving everywhere and really fast, so they have no control over how they move because of how fast they are.

(refer to my bumper car example in answer b, in bold)

Answer:

Origin: L. Infinitas; pref. In- not – finis boundary, limit, end: cf. F. Infinite. See Finite.

1. Unlimited extent of time, space, or quantity; eternity; boundlessness; immensity. There can not be more infinities than one; for one of them would limit the other. (Sir W. Raleigh)

2. Unlimited capacity, energy, excellence, or knowledge; as, the infinity of god and his perfections.

3. Endless or indefinite number; great multitude; as an infinity of beauties.

4. (Science: mathematics) a quantity greater than any assignable quantity of the same kind.

Mathematically considered, infinity is always a limit of a variable quantity, resulting from a particular supposition made upon the varying element which enters it.

5. (Science: geometry) That part of a line, or of a plane, or of space, which is infinitely distant. In modern geometry, parallel lines or planes are sometimes treated as lines or planes meeting at infinity. Circle at infinity, an imaginary circle at infinity, through which, in geometry of three dimensions, every sphere is imagined to pass. Circular points at infinity. See Circular.

Explanation:

Answer:

a. the blood pressure decreases. the bblood in the A that is the artery is higher as the artery carries the oxygenated blood which is directly pumped out of the heart.so the artery's pressure is higher where as the capillaries pressure decreases when compared with artery. the blood in the capillary flows slowly and smoothly as capillary needs time to exchange the substance between the body cells and the blood. the vein carry the deoxygenated blood back to the heart so their pressure is low.

b.the highest pressure is found in the artery because it carries the oxygenated blood and the heart pump the blood with great force thus tge artery have the highest pressure . and it also wanted to transport the oxygen quickly to other parts of the body.

c. valves. these prevent the backflow of the blood in capillary as the blood moves against the gravity.so valves prevent the blood from going back . therefore the valves help the blood in veins to move back to heart. (not sure)

Answer:

In this case, it is likely that the polypeptide chain assumed an alpha helix configuration because the lipid bilayer did not have beta-barrel proteins.

Explanation:

A polypeptide chain is naturally polar, however, a lipid bilayer is naturally non-polar. This makes it difficult and even prevents the polypeptide chain from crossing a lipid bilayer, since the composition of these two elements does not allow them to mix. In that case, the polypeptide chain has two options to take to successfully cross the lipid bilayer.

The first option that the polypeptide chain has is to allow the creation of twisted beta sheets in the shape of a closed barrel in its structure. This only works if the lipid bilayer has beta barrel proteins in its composition to act as a transport channel for the polypeptide chain. However, few lipid layers have this protein.

Most likely, the polypeptide chain assumes an alpha helix conformation to cross lipid bilayers that do not have beta-barrel proteins. By assuming the beta conformation, the polypeptide chain reinforces the hydrogen bonds present in its composition, allowing it to cross the lipid bilayer without having its conformation and structure disassembled.

Answer:

Aquifers but since there is no answer choice I say groundwater .

Hope this helps .

Water located in wells underground is ground water. Therefore, the correct option is option C.

Water that is found below the earth's surface in cracks in rocks and the crevices between soil particles is known as groundwater. It is essential for maintaining ecosystems on our planet and supporting human activities. Groundwater is created and made available by precipitation and surface water that seeps into the ground. It gathers in subterranean aquifers, which are enormous water reservoirs contained in permeable rocks or sediments. The thickness and depth of these aquifers vary. Groundwater supply is influenced by elements like rainfall, geology, and human use. Groundwater is an important resource since it is necessary for a variety of purposes. It provides over half of the world's population with their main supply of drinking water.

Therefore, the correct option is option C.
