What can you infer about water in the air?
Water in the air contains contaminates.
Water in the air does not have contaminates.
Water in the air is very large.
Water in the air is very salty.
Answer:
I believe water in the air contain contaminates c:
Explanation:
Heat from the Sun causes water to evaporate from the surface of lakes and oceans. This turns the liquid water into water vapor in the atmosphere. Plants, too, help water get into the atmosphere through a process called transpiration! ... Water can also get into the atmosphere from snow and ice.
Final answer:
Water in the air contains contaminants because all naturally occurring water can absorb substances from the environment. Human activities and natural phenomena both contribute to the contamination of atmospheric water vapor.
Explanation:
Based on the information provided, we can infer that water in the air does contain contaminates. All naturally occurring water, including atmospheric water vapor, can absorb various substances from the environment, such as minerals, pollutants, and biological materials. As water is a good solvent, it easily dissolves materials it comes across, leading to the presence of contaminants. While environments can handle a degree of contamination, there is a threshold beyond which the contamination becomes harmful to health and ecosystems.
Pollution happens when contaminants are introduced into the environment at damaging levels. Water vapor in the air can be contaminated by human-induced pollution, such as industrial emissions, or by natural phenomena, like volcanic eruptions. It is our human activities – agricultural, industrial, and sewage treatment processes, among others – that have a significant impact on the quality of water in the environment. This holds true for the water in the air, as it is part of the global water cycle and is subject to the same contamination processes as surface and ground water.

PLEASE HELP! In this simulation, the masses of the planets were all the same. Do you think if the masses of the planets were different, it would affect the results? Why or why not?
Answer:
It would certainly make a difference.
Explanation:
The mass of a planet determines how thick the planets atmosphere would be, if it can even sustain an atmosphere. If all the masses are the same, all of the large planets would not be able to sustain life, while all of the smaller, denser planets still have a chance.
The mass of a planet also affects it’s gravitational pull. If all of the planets had the same mass, they would all have the same gravitational pull, meaning that they would all attract the same amount of asteroids, meteors, and other spacial objects.
Overall, the simulation would certainly be different, for many, many reasons. The above are only two, and if you would like more, just add a comment and I can give you more.
As per the stimualtion if the mass of the plants is the same, It would not create any difference.
What masses of planets different?The mass of a planet are different as they are made of different compositions and their mass determines their thickness and thinness.
The mass is a indication the role of gravity and the density of atmosphere. If the masses are the same then all planets would be of the same size and many would not be able to sustain life.

Does a cell use energy when molecules diffuse in or out of the cell?
Why?
Answer:
There are two major ways that molecules can be moved across a membrane, and the distinction has to do with whether or not cell energy is used. Passive mechanisms like diffusion use no energy, while active transport requires energy to get done.
Explanation:
The cell use energy when molecules diffuse as there are two major ways that molecules can be moved across a membrane, and the distinction has to do with whether or not cell energy is used. Passive mechanisms like diffusion use no energy, while active transport requires energy to get done.
What is diffusion?Diffusion has been defined as the process of passive transport in which a single substance would moves from an area of high concentration to an area of low concentration until the concentration has been equal on both areas.
Diffusion distance rate of diffusion depends on the distance molecules have to travel. The greater the diffusion distance needs to travel the longer it takes to move.The greater the distance that a substance must travel, the slower the rate of diffusion. Oxygen moves from the alveolus to the capillary through the respiratory membrane which means the thickness of the respiratory membrane is diffusion distance.
Therefore, The cell use energy when molecules diffuse as there are two major ways that molecules can be moved across a membrane, and the distinction has to do with whether or not cell energy is used. Passive mechanisms like diffusion use no energy, while active transport requires energy to get done.

Final answer:
Salamanders have moist skin and need water for reproduction, unlike turtles which have dry scales and a hard shell. Salamanders are amphibians with varying modes of respiration and share a facial resemblance with frogs and toads.
Explanation:
What separates a salamander from a turtle? One of the key distinctions is their skin; salamanders have moist skin, which is quite different from the dry scales on a turtle's skin. Salamanders are also amphibians and share some evolutionary traits with frogs and toads, such as a similar facial structure and the need for a watery environment for reproduction. Unlike lizards that are purely terrestrial, salamanders are semiaquatic, meaning that they spend part of their lives in water, particularly for the purpose of reproduction.
Salamanders, like the marbled salamander, typically have a slender body, short legs, a long tail, and moist skin. While most have this general body plan, respiration among salamanders can vary. For example, some use lungs, others breathe through their skin or the lining of their mouth. In contrast, turtles have a hard shell for protection and are reptiles, living both on land and in water but not requiring water to reproduce as amphibians do.

4. Different restriction enzymes cut the same DNA molecule into different
numbers of fragments, because different restriction enzymes have
a. different base pairs
b. different sticky ends
c. different restriction sites
d. different nucleotide sequences
Final answer:
Different restriction enzymes cut DNA at specific restriction sites, each with its own recognition sequence, leading to different numbers of DNA fragments.
Explanation:
Different restriction enzymes cut the same DNA molecule into different numbers of fragments because they recognize different restriction sites on the DNA sequence.
Each restriction enzyme is able to identify its specific recognition sequence, which is often a palindromic sequence of nucleotides, and cut the DNA there. This can result in varying numbers of DNA fragments with different sizes.
These fragments typically have either 'sticky ends' or 'blunt ends', depending on the manner in which the enzyme cuts the DNA.
These ends can be used to recombine the DNA fragments with complementary DNA sequences in processes such as molecular cloning and recombinant DNA technology.

20. __________________ and _____________________ are early tetrapods that do not have features
unique to fish. Describe how these two species differ anatomically and what that means about where they each lived.
Answer and explanation:
6. In fossils, what anatomical evidence indicates that gills were present?
The anatomical evidence found in the fossils, such as special bone structures in the shoulders and skulls to support the gills, allows us to know the existence of these structures in some ancient species.
7. Many transitional species had gills, which means they lived in aquatic environments.
Gills are structures which allow people to breathe underwater, and many evolutionary transition species had them, such as the Tiktaalik, which also had lungs.
The existence of gill and lung respiration is what leads us to think that transition species were the first to leave the aquatic habitat to become terrestrial tetrapods.
8. Lungs allow an animal to breathe air. Why did this adaptation evolve?
Species considered transitional between fish and land animals were equipped with both gills and lungs.
It is suggested that the appearance of the lungs is due to the lower concentration of oxygen in the water and the need to obtain oxygen from another source, such as air, where the oxygen concentration is higher. In these circumstances, increased oxygen demand forced some animals to leave the aquatic habitat.
9. Tetrapods use lungs to breathe. Do any modern tetrapods have gills? Explain.
Some present-day tetrapods - such as salamanders, toads and frogs - are amphibians, and in their larval stage they remain in an aquatic habitat, so they are equipped with gills during this stage of their life cycle.
In amphibians like the frog, the passage from the larval stage to the adult stage involves a process called metamorphosis, in which the gills disappear and the lungs develop, in addition to the appearance of the four limbs, which are absent in the larva.
13. Most modern tetrapods have five digits on front limbs and five digits on back limbs, although some species have fewer. How does this number compare to the number of digits on the limbs of transitional fossil forms?
The transitional species originally had fins, but fossils of the first tetrapods have been found with developed limbs and five or more digits, representing an equal or greater number of digits than current species.
An example of a larger number of toes is represented by the genus Acanthostega, with eight toes on each limb.
14. Why do many of the transitional fossils between fish and tetrapods have flat heads?
Many of the transition fossils between fish and tetrapods have flat heads, from top to bottom, because these species participated in the transition between aquatic and terrestrial habitat, adapted to living in shallower waters near the surface, and with gill and lung breathing capacity.
15. How did the anatomy of the shoulder and head change during tetrapod evolution?
The changes in the anatomy of the shoulder and head during the evolution of the tetrapod were basically three:
The bony skeleton of the shoulder is separated from the skull, which in aquatic animals was attached. The appearance of the neck, between both structures. Development of an independent movement of the skull, with respect to the shoulder and the rest of the body.16. Tiktaalik and Acanthostega are fossil species have characteristics unique to fish as well as characteristics found in fish and tetrapods. Describe the characteristics of lobe-finned fish that are similar to those of tetrapods.
Lobe-finned fish -called sarcopterygians- like dipnoi, are lungfish, given the existence of functional lungs in their body. Another characteristic of lobefish is that each of their fins is attached to a single bone, as in the case of the humerus and femur of mammals.
The existence of lungs and the attachment of the limbs to a bone are common features among lobed finfish and tetrapods.
17. Which lobe-finned fish is alive today?
The coelacanth is one of the oldest species of fish that exist, as they are lobe-finned fish that were thought to be extinct, but still exist.
The characteristic of possessing lungs and bony skeleton relates them to the actual lung fishes and to the terrestrial vertebrates.
18. Acanthostega and Icythyostega have been called fish-like tetrapods. Explain why they are described as such and describe the environment in which they probably lived.
Both the Acanthostega and the Icythyostega were animals characterized by having four extremities and be equipped with gills and lungs at the same time, which determines that they are called tetrapods similar to fish.
Their characteristics made them suitable for living in aquatic and terrestrial environments, so they probably inhabited shallow waters or even the surface of the earth.
The origin of the fish from the tetrapods has been detected with the fossils and their study.
In fossils, the anatomical evidence indicating that gills are present has been the bone structure in the shoulder and skull to support gills.The transitional species having gills have been the indication that they live in an aquatic environment and utilize gills for respiration.Lungs allow the animals to breathe in air.

According to the article, how does the intermittent recovery test differ from the intermittent endurance test?
The intermittent recovery test differ from the intermittent endurance test in the way that intermittent recovery test uses twenty-five meter long strip of floor space instead of twenty-two and half meter long strip.
Explanation:
In intermittent endurance test, twenty-two and half meter long strip divides the floor into two sections - one of twenty meter and another of two and half meter. The subject is supposed to run in the longer section a per CD until he reaches the other side or he hears the recorded beep.
One hearing the beep, he must turn and return back to his starting point. On reaching there, he is given five seconds time to walk or jog in the shorter section which is of two and half meter.
If the subject fails to cover twenty meter long section before beep sound, a warning is issued to him.
In case of intermittent endurance test, twenty-five meters long strip is used to divide the floor section into parts, one of one of twenty meter and another of five meter. In this test extra five seconds are also added for active break time, thus making it of ten seconds.

The energy of a UV wave from the sun becomes part of the internal energy of the sidewalk causing the sidewalk to heat up, then the wave's energy was
Answer:
The wave energy was transformed into thermal energy.
Explanation:
Thermal energy is energy related to the generation of heat within a system. This is because thermal energy arises when potential energy agitates the molecules of a system, generating kinetic energy. This agitation of the molecules promotes heat to the system, transforming the kinetic energy into thermal energy and making the system temperature higher.
An example of this can be seen when the waves coming from solar energy promote the heating of a system, like a sidewalk for example. These waves promote the movement of the sidewalk molecules, transforming the wave energy into thermal energy.
A cows grazing in the field. Under what conditions does the cow have relative motion
Relative motion has been defined as the motion or the velocity of the object in reference to the start point. The cow will have relative motion if it changes its position compared to the reference.
What is relative motion?Relative motion or relative velocity has been the velocity and motion of the object with reference to the initial point and to the other body. It defines the rate of change occurring in two different bodies at the same time.
It can be used to show the relative motion of the cow as a reference point or frame is taken as the point to which the motion or the velocity of the cow is taken into consideration. The field is the fixed point to which the cows show motion.
Therefore, the relative motion of the cow can be explained based on the reference point of the field.

#SPJ2
Relative motion between the cow and its surroundings occurs when either the cow is moving while the surroundings remain stationary, or when both the cow and the surroundings are in motion but with different velocities or directions.
When the cow is grazing in a stationary field, there is no relative motion as both the cow and the field are moving together with zero relative velocity.
However, if the cow is walking across the field or if the field is being traversed by other elements such as wind or water currents, relative motion between the cow and the surroundings arises.
Additionally, if the cow is stationary while the field is being traversed by, for example, a strong wind, relative motion occurs.
In essence, relative motion between the cow and its surroundings happens when there is a difference in their velocities or directions of movement.

anaphase II, telophase II, prophase II, metaphase II
prophase II, telophase II, anaphase II, metaphase II
Answer: Prophase II, metaphase II, anaphase II, and telophase II
Explanation: In prophase the spindle forms to prepare the chromatids for splitting. Metaphase lines up the chromosomes at the equator. In anaphase, the sister chromatids split, and in telophase seperate cells are created.
The spindle develops during prophase to get the chromatids ready for splitting. The chromosomes are aligned near the equator during metaphase. Sister chromatids split during anaphase, and separate cells are formed during telophase. Thus, option B is correct.
What is the importance of steps of Meiosis II in cell cycle?The second division of meiosis, known as meiosis II, occurs when each chromosome's chromatid is evenly distributed across the daughter cells. The interphase, which comes before meiosis II, is a period in which DNA is not replicated.
It keeps the number of chromosomes in sexually reproducing organisms constant. Haploid gametes are created from a diploid cell, and they then combine to create another diploid cell. 2. It limits chromosomal number multiplication and preserves stability.
Therefore, Each time cells divide, it causes the development of four daughter cells. The daughter cells have the same size and structure as the mother cell, but have a different number of chromosomes.
