What is one reason water can remain in the liquid state on Earth?
A. Earth's atmosphere is deep enough to allow water to cycle through
its solid, gas, and liquid states.
OB. Earth's surface is continually bombarded by comets, which add
liquid water.
OC. Earth's distance from the sun keeps the temperature just right for
liquid water to exist.
OD. Earth's atmosphere is warm enough to prevent water vapor from
condensing.

Answer:
c
Explanation:
water boils at 100 degrees Celcius and freezes at zero degrees Celcius. if you want to keep water in a liquid phase, the temperature has to be between 0 and 100 therefore earth is the only planet that is able to keep water in a liquid phase as it is not too hot nor too cold

Use the following information to calculate the correct frequencies: In a population of
Pennsylvanians, only 18% of individuals express the recessive trait of Syndactyly or webbed finger
(formulas: p+q=1 and p²+2pq+q2²=1)
a. What percentage of the population are not Webbed?
If we have the recessive genotypic frequency, we can calculate the phenotypic frequencies in a population in Hardy-Weinberg equilibrium. The percentage is 82%.
What si the Hardy-Weinberg equilibrium theory?The Hardy-Weinberg equilibrium theory states that allelic and genotypic frequencies remain the same through generations in a population that is in equilibrium.
The allelic frequencies in a locus are represented as p and q. Assuming a diallelic gene,
Allelic frequencies
The frequency of the dominant allele f(X) is pThe frequency of the recessive allele f(x) is qGenotypic frequencies after one generation are
• p² ⇒ H0m0zyg0us dominant genotypic frequency,
• 2pq ⇒ Heter0zyg0us genotypic frequency,
• q² ⇒ H0m0zyg0us recessive genotypic frequency.
The addition of the allelic frequencies equals 1
p + q = 1.
The sum of genotypic frequencies equals 1
p² + 2pq + q² = 1
Available data:
18% of individuals express the recessive trait of Syndactyly
Let us say that the dominant allele is A and the recessive allele is a.
The dominant allele A codes for normal finger.The recessive allele a codes for webbed finger.Assuming this gene expresses complete dominance,
H0m0zyg0us dominant and heter0zyg0us -AA and Aa- individuals have normal finger.Their frequency in the population is p² + 2pq.
h0m0zyg0us recessive -aa- individuals have webbed finger.Their frequency in the population is q².
Individuals that express Syndactyly have webbed finger and their genotype is h0m0zyg0us recessive, aa. Their frequency in the population is q².
q² = 18% = 0.18
We can get the frequency of individuals with normal fingers by clearing the following equation,
p² + 2pq + q² = 1
p² + 2pq + 0.18 = 1
p² + 2pq = 1 - 0.18
p² + 2pq = 0.82
The frequency of individuals with normal fingers is p² + 2pq = 0.82 = 82%.
The percentage of the population are not Webbed is 82%.

A. pharynx
B. larynx
C. trachea
D. Esophagus
The cavity which separate or in between the nose and the mouth is the nasal cavity.
The nose and the mouth meet at a junction called the pharnx; option A

What are Vascular tissues?Vascular tissues in plants are specialised tissues which transport nutrients and water through the plant. They are made up of two distinct kinds of tissues: xylem and phloem.
Xylem is in charge of carrying water and minerals that are dissolved from the plant's roots to its leaves. It is made up of many cell types, such as tracheids, vessel components, and fibres. Tracheids and vessel elements are long, hollow structures that create lengthy tubes when stacked end to end.
Sugars and other organic compounds are transported from the leaves to the remainder of the plant by phloem. There are two sorts of cells in it: sieve tube elements and cell companions. Sieve tube components are long, narrow cells that run end to end.

Jayden is researching the Earth's
plates. How would he describe the
relationship between the Earth's plates
and soil and rocks?
Answer:
Geologists have hypothesized that the movement of tectonic plates is related to convection currents in the earth's mantle. Convection currents describe the rising, spread, and sinking of gas, liquid, or molten material caused by the application of heat.
The Earth's plates have a crucial relationship with soil and rocks. This connection is characterized by the plates' movement influencing the formation, distribution, and composition of soil and rocks across the planet.
The asthenosphere, which is semi-fluid beneath them, is separated into many tectonic plates that make up the Earth's lithosphere. Convective currents in the mantle cause these plates to move constantly. Processes like subduction, in which one plate falls beneath another, and rifting, in which plates move apart, are fueled by this movement. Mountains, valleys, and oceanic basins are all the result of these dynamic processes, which have a significant impact on the surface of the Earth.
Through volcanic activity and metamorphism, interactions between the plates also aid in the production of different types of rocks. Therefore, the distribution and makeup of soils and rocks on our globe are significantly shaped by plate movement, which also has an impact on landscapes, ecosystems, and geological characteristics.
