Explanation:
Why do planets close to the sun have thin atmospheres and the planets far away from the sun have thick atmospheres. Use what you know about the nebular theory.
Answer:
There are two primary factors: size and distance from the Sun. Gravity helps planets and moons to hold on to their atmospheres, so small planets/moons such as Mars and the Moon have thin atmospheres. The reason why the outer planets are larger is probably down to two major factors. The first is simply the amount of material available which may be accreted to a planet. Clearly, the further away from the Sun, the longer the orbit (twice as far means an orbit twice the physical length).

The swallowing phase where the velopharynx closes forcefully and larynx completely closes at 3 levels is the...
a. Tongue preparatory phase
b. Pharyngeal transport phase
c. Oral transport phase
d. Laryngeal transport phase
Answer:
b. Pharyngeal transport phase
Explanation:
During the pharyngeal phase, the vocal folds close to keep food and liquids from entering the airway.
Swallowing the velopharynx closes forcefully and the larynx completely close at the level of the pharyngeal transport phase this action seal the airway passage, hence option b is correct.
What is swallowing ?According to where the bolus is located, the swallowing process is often split into oral, pharyngeal, and esophageal phases. When consuming solid food vs drinking liquid, the food moves differently through the oral cavity and into the oropharynx.
The tongue closes the oropharynx while it is in the pharyngeal phase. The proximal pharyngeal wall and soft palate serve as a barrier to the nasopharynx.
The laryngeal entrance is sealed off by the vocal cords and arytenoids, and the epiglottis swings down to cover the laryngeal vestibule. These acts close up the pharyngeal cavity's airway.
Therefore at 3 levels, the velopharynx closes forcefully and the larynx completely closes in the pharyngeal transport phase action to seal the airway passage, hence option b is correct.

Ice wedging into the rock and breaking and crAcking the rock and soil
Answer:
Ice wedging is a process that happens when water gets into the cracks of concrete, stones, other forms of the Earth, and freezes. When the water freezes, it expands and pushes the rock from the crack which either separates and turns it into two rocks, or the rock might form together again and just be a larger rock. This process happens in Winter and usually finished in Spring when the ice between the rocks melt. I have described the process of ice wedging for you.

What is DNA?
DNA is a hereditary material which is present in human beings as well as all other living organisms. Every cell which is present in an organism's body has DNA which is the same. Most of the DNA is situated in the cell's nucleus and small amount of it can be found in the cell's mitochondria as well.
Information which is stored in DNA is stored as codes made up of four chemical bases namely, adenine, thymine , cytosine and guanine.Human DNA consists of 3 billion bases .The order of the bases determines information which is required for building and maintaining an organism.
DNA bases are capable of pairing up with each other. Adenine pairs with thymine and guanine pairs up with cytosine .Each base is also attached to a sugar molecule and a phosphate group. A base, phosphate sugar are together called as nucleotides.

The number of waves passing the observer per second is:
- the wavelength
- the amplitude
-the frequency
- the period
Answer:
frequency
Explanation:
comment if im wrong
The number of waves passing the observer per second is the frequency. Hence, the correct option is C.
What is frequency?Frequency refers to the number of waves that pass from a fixed point in unit time. It is a measure of the rate of repetition of a periodic phenomenon such as vibration or a wave.
It is measured in hertz (Hz), an international unit of measure where 1 hertz is equal to 1 cycle per second. The more cycles that occur per second, the higher the frequency of the system is.
For example-The human heart beats at a frequency of 68 beats per minute.
In general, frequency is a very important concept in many fields including physics, engineering, music and the natural sciences, and it is used to describe and analyze a wide range of periodic phenomenon.
Therefore, the correct option is C i.e., frequency.

By analyzing this equation, which property of photosynthesis can be identified?
A the chemical changes that occur during the light independent reactions
B. the chemical changes that occur during the light dependent reactions
C. the source of carbon atoms in the carbohydrate product
D. the identities and roles of electron carriers
Answer:
A
Explanation:
Occur during light reaction process to manufacture food and release oxygen
.
The overall chemical equation that describes photosynthesis is the chemical changes that occur during the light independent reactions(option -A).
Why is the process of photosynthesis named that?Light energy is converted into chemical energy during photosynthesis by phototrophs, which is subsequently used to drive cellular functions. The form in which the chemical energy is stored is in the form of sugars, which are produced from water and carbon dioxide.
Photosynthesis' main job is to transform solar energy into chemical energy and then store that chemical energy for later use. The majority of the planet's biological systems are propelled by this process.
Anoxygenic and oxygenic photosynthesis are the two forms. The former is the more prevalent type, found in plants, algae, and cyanobacteria, and they both operate on very similar principles.

The flame of many stove burners is blue, but the wires of a toaster glow orange. How do you think the temperatures of these two cooking appliances compare?
Answer:
the hotter is it, the more bluish it is. And the more reddish it is, the colder it is
just like the bluer the star, the hotter it is, the redder the star, the colder it is.
Comparing the temperatures of the two cooking appliances ; The temperature emitted in stove burners are hotter than the temperatures emitted by the toaster
White-Blue flames are the hottest flames when combined together but the hottest single flame is the blue flame burning between ( 2,600º F and 3,000º F). Blue flames have more oxygen than other types of flames, hence they burn hottest and this is because gases when burnt are hotter than other materials. while
The orange flame of a toaster burns at a temperature between ( 1100°C to 1200°C) . releasing carbon monoxide as it burns.
Hence we can conclude that The temperature emitted in stove burners are hotter than the temperatures emitted by the wires of a toaster.

By their experimentation using the Neurospora fungus, Beadle and Tatum were able to propose the far-reaching hypothesis that ________
Answer:
one gene produces a specific enzyme
Explanation:
The one gene-one enzyme hypothesis states that one gene specifies the production of a specific enzyme. This concept is based on Beadle and Tatum's experiment. Beadle and Tatum irradiated Neurospora spores with X-ray in order to induce mutations, then they crossed mutant strains with non-irradiated Neurospora strains. Finally, Beadle and Tatum observed that some mutant spores would not grow without addition of arginine (Arg) residues to the culture, thereby suggesting that each gene is responsible for the synthesis of one enzyme.
