Answer:
Volume of mercury decreases due to close arrangement of particles.
Explanation:
When we freeze liquid mercury, its volume decreases and density increases from from 13.69 g/cm3 to 14.184 g/cm3 and form a solid mercury. The motion of particles stop when we freezes liquid mercury and the particles settles into a stable arrangement. If we cool the liquid mercury and the temperature reaches to -38.83 °C, then it converts from liquid into solid substance.

Answer:
The question lacks options, the options are:
A. understand the viewpoint of other people.
B. realize that the term heavy describes an object one way and the term big describes it another way
C. understand that six ounces of liquid in a jar and six ounces in an elongated tube are equal.
The answer is C
Explanation:
Piaget proposed the theory of cognitive development, which talks about how human intelligence is developed. Piaget worked with Children because he believed they played a significant role in the development of cognitive intelligence. Based on his work, he proposed four stages of cognitive development viz: sensorimotor, preoperational, concrete operational and formal operational stages.
However, in the preoperational stage, Piaget described children between ages 2-7 as being in this stage of cognitive development where they are yet to comprehend mental logic. One characteristics of this stage is CONSERVATION, which is the ability to know that changing a substance's appearance doesn't change the properties of that substance. Piaget proposed that Children between the ages of 2-7 lacked this conservative characteristics.
He performed an experiment where he used two beakers with the same amount of liquid. He then emptied the contents of one of the previous beakers into a new beaker with different shape (longer). Piaget was able to notice that Children at the pre-operational stage were unable to understand that the contents of the two beakers (longer one and previous beaker) were still the same despite the beaker has been changed.
Hence, according to Piaget, a child has acquired the cognitive skill of conservation when he/she is able to understand that six ounces of liquid in a jar and six ounces in an elongated tube are equal.

B. G1, S, G2, Mitosis, Cytokinesis
C. S, G1, Mitosis, G2, Cytokinesis
D. S, G1, G2, Mitosis, Cytokinesis
Answer:
B. G1, S, G2, Mitosis, Cytokinesis
Explanation:
G1 is the first stage of the cell cycle, and it is essential for cell growth.
Next, the S (Synthesis) phase occurs. This phase involves DNA synthesis to prepare the cell for division.
G2 is the next phase, and it involves preparing and growing the cell for mitosis.
Mitosis is the next stage, where the cell divides into 2.
Lastly, Cytokinesis occurs after mitosis, and it creates the two daughter cells.
So, the correct answer is B. G1, S, G2, Mitosis, Cytokinesis

11) base pairs
12) G with C and A with T
13) 1953
14) died
15) unwound
16) synthesized; a new molecule
Explanation:
Nitrogenous bases are used to construct nucleotides. Until the discovery of the helical shape of the DNA molecule, were only possible to identify the genetic material (chromosomes) by the microscope. Chromosomes are composed of DNA and proteins (histones). Nucleotides are the building blocks of the DNA molecule. The X-ray diffraction data obtained by Rosalind Franklin were used to decipher the DNA structure. The ball-and-stick is a molecular model where atoms are represented by spheres and bonds are represented by rods. Chargaff's rules indicate that the content of cytosine is equal to guanine and adenine is equal to thymine. Rosalind Franklin died of ovarian cancer in 1958. The double-stranded DNA molecule must be unwound and then the DNA strands serve as templates to synthesize identical DNA molecules.

scientists at the tar pits discovered that many of the smaller animals they extracted from the pis still exist around los angeles today. But many of the larger mammals such as wooly mammoths and saber toothed tigers are now extinct. I believe this is the case because since bigger beasts couldnt take shelter in small protected burrows, perhaps they were done in by fierce environmental conditons.

Trees grow more quickly in the ________ than the ________, and the tree rings show up as ________ colored bands.
summer, winter, darker
summer, winter, lighter
winter, summer, lighter
winter, summer, darker
Answer:
Its summer, winter, darker.
Explanation:
This is the answer I hope it helps you out.
Trees grow more quickly in the summer than in the winter, and the tree rings show up as darker colored bands.
What are seasons?A season exists the year that stands determined by particular climate conditions. The four seasons—spring, summer, fall, and winter—follow one another regularly. Each includes its light, temperature, and weather designs that repeat yearly.
Summer exists the hottest of the four temperate seasons, happening after spring and before autumn. At or centered on the summer solstice, the earlier sunrise and latest sunset happen, daylight hours exist longest and dark hours exist shortest, with day length falling as the season progresses after the solstice.
Winter, the coldest season of the year, between autumn and spring; the name arrives from an old Germanic word that represents “time of water” and guides to the rain and snow of winter in middle and increased latitudes.
Hence, Trees grow more quickly in the summer than in the winter, and the tree rings show up as darker colored bands.

A projectile is fired vertically upward at an initial velocity of 100 m/s. How high will it rise? How long will it take to reach that height?
The question is solved using the equations of motion
According to the equations of motion:
[tex]v^2 = u^2 -2gh[/tex]
v = final velocity
u = initial velocity
g = acceleration due to gravity
h = height
Note that at the maximum height, the final velocity (v) = 0 m/s
so we can write:
[tex]u^2 = 2gh[/tex]
[tex]h = \frac{u^2}{2gh}[/tex][tex]h= \frac{100^2}{2 * 10}[/tex]
h = 500 m
The time taken is obtained from:
[tex]v= u - gt[/tex]
since v= 0 at maximum height
[tex]u = gt\\\\t= u/g\\\\t= 100/10\\t = 10 s[/tex]

The diagram summarizes the light-dependent reactions of photosynthesis. A diagram shows the light-dependent reactions of photosynthesis. x goes to the light dependent reaction. The light dependent reaction goes to chemical energy and oxygen. What is the input of the light-dependent reactions, labeled X? CO2, H2O, O2, and light CO2, H2O, and light CO2 and H2O H2O and light
Answer:
Although there is no diagram attached to this question but it can be answered based on the general knowledge of photosynthesis. The answer is:
H2O and light
Explanation:
Photosynthesis is a unique phenomenon that occurs in the Chloroplast of plant cells. It is the process by which plants and other autotrophs obtain their energy source (food) in the presence of sunlight. Photosynthetic process occurs in two distinct stages viz: light dependent reaction and light independent reactions.
The light dependent reaction, as the name implies, is dependent on light to occur. It occurs in the Thylakoid membrane of the Chloroplast, where a photon of light is captured by the Chlorophyll pigment and the energy is used to split molecule of water in a process called PHOTOLYSIS OF WATER. The transfer of electrons across the thylakoid membrane creates a proton pump, which is used to generate ATP and NADPH. NADPH and ATP are electron and energy carriers respectively which enters into the light independent stage in order to synthesize glucose (sugar).
In a nutshell, the inputs of the light dependent stage are LIGHT from the sun, and water (H2O), which provides the proton and electron when split.
