If water vapor continues to increase in our atmosphere, what changes would you expect in fresh water lakes?
A: lake temperatures will decrease, but dissolved oxygen in water will increase.
B: lake temps will decrease along with dissolved oxygen.
C: lake temps will increase, but dissolved oxygen will decrease.
D: lake temps will increase along with dissolved oxygen.
Answer: Option (C)
Explanation:
Temperature and dissolved oxygen is inversely proportional to each other i.e if temperature is high then dissolved oxygen will be low and if temperature is low then dissolved oxygen will be high.
Thus, we can conclude that when the water vapor content increases in the atmosphere, the lake temperature eventually will rise whereas the dissolved oxygen will get subsequently reduced.
Hence the correct option is (C)

According to the density profile shown here, at which depth would you find the coolest, saltiest waters?
A. depth B
B. depth A
C. depth C
D. You cannot tell from this graph
Answer:
C. depth C
Explanation:
From the chart you can teel that the most dense, coolest and saltiest waters can be found at the deepest levels of depth, in this case the deepest from the options would be located at less than 3,000 meters and it would be point C. As we know as we go depeer into the water of the ocean pressure increases and with that density of the water also increases, under normal circumstances the sunlight and sun heat is the only thing that is able to heat up the water of the ocean, so the deeper you go, the less sunlight and less sun heat is available so the waters become cooler.
Curious Carl and his lab partner were trying to answer the question: "What is white light?" To do this, Carl directed an intense beam of light through a glass _________ that had been placed on a piece of white paper. As the beam of light emerged from the opposite side, a rainbow of colors was produced on the white paper.
Carl directed a beam of light through a glass prism. The prism causes the white light to be refracted. Each wavelength bends at a different angle, so the visible spectrum is seen on the opposite side, emerging from the prism.

How do the nutrients in soil become building materials for a plant to grow?
The nutrients from the soil is taken up by the roots to be distributed to the entire plant. The plant absorbs the nutrients into its cells and utilized by the leaves, stem, trunk. They are also used to grow flowers and to bare fruits.
Moreover, the nutrients are divided into two groups; first the macronutrients which is needed by the plants in large amount such as nitrogen, phosphorus, potassium, calcium, magnesium and sulfur. Second group is the micronutrients, needed in tiny amounts that include zinc, copper, manganese, boron, iron, sodium and cobalt. These two groups are essential for normal plant growth and development.

Which statement presents a commonly-found format for hypothesis
Trees maintain the balance between gases in the air, removing carbon dioxide from the air and releasing oxygen.
Answer:
Photosynthesis is correct answer.
Explanation:
Various gases are found in the atmosphere, Oxygen and carbon dioxide are the two most important gases for the survival of plants and animals. Animals and human beings require oxygen to stay alive, while plants need carbon dioxide for producing food and photosynthesis. Animals breathe the oxygen which is prepared by the plants. Marine animals also take oxygen dissolved in Oxygen. Plants use the process of photosynthesis for producing oxygen, during this process plants take in the carbon dioxide through the tiny openings on their leaves and release the oxygen as a waste product.
why must a tourniquet be removed prior to removing the hypodermic needle
A tourniquet must be removed before the hypodermic needle to prevent hematoma, excessive bleeding, and bruising, ensure patient comfort, and avoid nerve and tissue damage due to restricted blood flow.
The tourniquet must be removed prior to removing the hypodermic needle to prevent potential complications such as hematoma formation, excessive bleeding, or bruising at the puncture site. A tourniquet is typically applied during venipuncture or the insertion of the needle to restrict blood flow, which helps in vein dilation making the vein more visible and palpable. Once the blood draw is complete, it's critical to remove the tourniquet before the needle is withdrawn. This is because the tourniquet's pressure can cause blood to rapidly fill the vein when the needle is still in place, and upon its removal, this can lead to blood leaking out of the puncture site or other damage to the vessel.
Additionally, prolonged application of a tourniquet can cause unnecessary discomfort to the patient, as well as potential damage to nerves and tissue due to restricted blood flow. Thus, prompt removal of the tourniquet is a key step in a safe and effective venipuncture procedure.

which statement correctly describes an example of the cohesive property of water
Explanation:
The water drop is made up of water molecules that like to stick together is an example of cohesive property of water.
Cohesion and adhesion are important properties of the water. Adhesion is attraction of water to other substances while cohesion is attraction of water to water. It affects every water molecule with on this Earth and also the interaction between the water molecules and other substances.
A property that allows the molecules and compounds of a substance to stick and bind together is called cohesion or cohesive property.
The correct statement about the cohesive property of water is:
Water that is poured onto a waxed surface will gather together to form droplets.
The water molecules are bonded together by hydrogen bonds.When the water is poured on the waxy surface then the water droplets come together and due to cohesive nature sticks to each other.Water exhibits adhesion and cohesion properties that allow them to bond to water molecules and other compounds.Therefore, water molecules show cohesive properties.

Describe the body covering, the method of support, and the forms of movement used by jellyfish.
Jellyfish are like corals, gorgonians and anemones they belong in the group called cnidarians also jellyfish is a kind of invertebrates. This animal group has stinging cells which they use both to capture their prey and also as a form of defense.the type of movement that the jellyfish has is called passive locomotion another example aside from jellyfish which is sailing are kiting (spiders) and rolling (some beetles and spiders).
Jelly fishes a water loving creature, is composed of 3 layers:
- An outer layer also known as ectoderm
- A middle layer- composed of thick jelly like substance called mesoglea
- An inner layer
The outer layer is covered with tentacles composed of stinging cells which are used to attack prey and for defense against the predators. There is present one single opening for mouth and anus.
As explained, the body is covered with tentacles which help jelly fishes to attach and support themselves in movement. The type of locomotion jelly fish has is passive locomotion.
A biology teacher asks his class to make models of a plant cell, an animal cell, and a bacterial cell. Aside from cytoplasm and the cell membrane, which other cell structure will the students need to make for all three models?
Answer:
The most possible answer would be ribosomes.
Explanation:
Bacteria is characterized as prokaryotes while animal and plants are eukaryotes.
Apart from the cytoplasm and cell membrane there are ribosomes are found in both prokaryotic cells eukaryotic cells, that can be bacteria, animal and plant cell. Ribosomes are essential for the translation of the DNA to form a protein.
In animal and plant cells they can be attached to the endoplasmic reticulum or free in the cytoplasm whereas in bacterial cells ribosomes are usually found as free ribosomes in the cytoplasm.
Thus, the correct answer would be ribosomes.

How did animals adapt/survive in hurricane katria (Plz help will mark brainliest)
Baby animals who live in trees, like squirrels and birds, are at high risk of being blown out of their nests and becoming lost, separated from their parents forever. One example is a litter of baby squirrels who were blown out of their nest and rescued by a Good Samaritan. “[I]f the animals had not been found they would have died within hours,” whether from shock or predators, the Daily Mail reported. But the news wasn’t all good for this squirrel family: sanctuary workers feared that their mother, whom rescuers could not locate, was still searching for her missing babies.
Birds are also in danger of death or dislocation from hurricanes. Some, like woodpeckers, know how to weather the storm — they stay in holes in trees. But migratory birds don’t fare as well. “Powerful winds from hurricanes and tropical storms can blow birds off course and push them hundreds of miles away from their home habitat,” according to the National Wildlife Federation (NWF). Some of them never make it back.
Non-migratory birds are in peril of losing their food sources. “Birds living in hurricane areas…suffer when their food supplies, such as fruits and berries, are stripped from trees and shrubs,” reports Birding.com. But at least the adults can stay put: their toes are designed to clench tight around branches, allowing them to resist even strong winds.
Sea mammals have it hard too. Kevin Coyle of NWF writes that “some dolphins and manatees have actually been blown ashore during major storms.”
Other sea life can suffer from the intermingling of salt and fresh water when a hurricane’s high winds cause storm surges, NWF explains: “[S]alty ocean water [piles] up and surge[s] onshore,” which “shifts the delicate balance of freshwater and brackish wetland areas. Creatures and vegetation that are less salt-tolerant will be harmed and many will not survive this influx of sea water.”

The general movement of low-pressure centers across the United States is from _____
The general movement of low-pressure centers across the United States is from West to east
Temperatures in the US are cooler than they are nearer to the equator, so air pressure is moderate than it is in the tropics. Because wind flows table clockwise nearby low pressure, winds normally blow from west to east, shifting weather operations to the east.
Generally, dominant winds blow east-west rather than north-south. This occurs because Earth's revolution creates what is perceived as the Coriolis effect. The Coriolis effect creates wind systems rotate counter-clockwise in the North Hemisphere and clockwise in the South Hemisphere
Low-pressure centers move from west to east across the United States due to prevailing westerly winds.
The general movement of low-pressure centers across the United States is from west to east. In the Northern Hemisphere, weather systems, including low-pressure centers (also known as cyclones), tend to move in an eastward direction due to the rotation of the Earth.
This eastward movement is often referred to as "westerly flow" and is a result of the Coriolis effect, which deflects moving air masses to the right in the Northern Hemisphere.
This means that low-pressure systems typically approach the western United States and then move eastward, affecting different regions as they travel across the country.
This eastward movement of weather systems is a fundamental aspect of the United States' weather patterns.

Check all statements below that are true. All organisms must compete for survival. When organisms struggle to survive, they usually mutate to increase chances of reproduction. Some organisms have phenotypes that make them better competitors than others in their environment. Animals undergo natural selection, but plants and other organisms generally do not. Natural selection continues to occur even today. Phenotypes found in the most successful members of a species become the most prevalent after several generations. A decrease in food availability will increase the variation in a population.

Which structure allow the flow of gases in and out of a leaf
Answer:
The correct answer is stomata.
Explanation:
The leaf structure is adapted for gas exchange between plants and the environment. The cells in the spongy mesophyll have tiny pores, termed as stomata, present in the leaf surface. Most of the stomata are found in the lower epidermis. These tiny pores control gas exchange. Opening and closing of stomata depend on the guard cell turgidity.
Diffusion of oxygen, carbon dioxide and water vapor in and out of the leaf is highest when these stomata are open.
Thus, the correct answer is stomata.
The _____ psychologists asserted that with respect to perception, the whole is greater than the sum of the parts.
Answer:
The given blank can be filled with Gestalt.
Explanation:
A school of thought, which looks at the mind of a human and behavior as a whole is known as Gestalt psychology. In making an attempt to produce the sense of the world surrounding us, the Gestalt psychologists suggest that one does not basically focus on every small constituent. However, the minds seem to perceive objects as part of the greater whole and as the constituents of more composite systems.
This branch of psychology plays a prime function in the contemporary development of the study of human perception and sensation.

In double stranded DNA, 13% of the strand is found to be adenine. How much would you expect thymine to be present?
13%
74%
26%
37%
The amount of thymine in double stranded DNA would be equal to that of adenine, which is 13%, according to Chargaff's rules.
Explanation:In double stranded DNA, if 13% of the bases are adenine (A), then we can expect the same percentage, 13%, to be thymine (T) according to Chargaff's rules. This is because adenine always pairs with thymine, forming hydrogen bonds. Hence, the amount of adenine equals the amount of thymine in a DNA molecule. Consequently, the percentage of thymine present would also be 13%, making option A the correct answer.
