PLEASEE ANSWER BEFORE FRIDAY APRIL 30 Seven students looked at a barometer, a weather device that measures air pressure. They had different ideas about air pressure. This is what they
thought:
Kimberly:
Glenn:
Rae:
Jeff:
Oliver:
I think air has to be moving to create air pressure.
Air pressure is a downward force.
The higher in the atmosphere, the greater the air pressure.
Air pressure is the same in all directions.
Air pressure increases as the number of air particles increases.
Warm air masses have higher pressure than cool air masses.
When air pressure decreases, it might rain or snow.
Cameron:
Jay:
Circle the names of the students you agree with and describe why you
agree. Describe your ideas about air pressure.
Answer: pressure is called atmospheric pressure, or air pressure. It is the force exerted on a surface by the air above it as gravity pulls it to Earth. Atmospheric pressure is commonly measured with a barometer. ... Meteorologists describe the atmospheric pressure by how high the mercury rises.

Select the characteristics of a hydrogen bond: hydrogen attracted to weakly positive atoms a gravitational force intermolecular force between hydrogen and oxygen, fluorine, or nitrogen an attraction between polar molecules
Answer:
intermolecular force between hydrogen and oxygen, fluorine, or nitrogen
an attraction between polar molecules
Explanation:
these are the correct answers....
Hydrogen bond is a type of intermolecular force between hydrogen atom and oxygen, fluorine, or nitrogen atoms Thus, the correct option is C.
What is Hydrogen Bonding?A hydrogen bond is a type of an intermolecular attractive force in which a hydrogen atom is covalently bonded to a small, highly electronegative atoms i.e., nitrogen, oxygen, and fluorine. Hydrogen atom is attracted to a lone pair of electrons on an atom in a neighboring molecule. Hydrogen bonds are very strong compared to other dipole-dipole interactions. However, these bonds are weaker than covalent bonds.
Hydrogen bonds are responsible for the surface tension properties of water. The bonds are also responsible for the relatively high boiling point of water molecules because of strong attractive forces.
Therefore, the correct option is C.

Answer:
The answer is C.
Explanation:
There are dominant alleles present in three out of four (CC, Cc, Cc) and the recessive is always cc. Three out of four make 75% and one out of four is 25%. That makes 75% dominant and 25% recessive.

what types of sedimentary rocks are formed from the remains of dead organisms
Answer:
Limestone
Explanation:
Limestone is formed from dead organisms and can also form from calcite in lakes, seas, etc.
Biochemical sedimentary rocks are formed from the remains of dead organisms.
What are biochemical sedimentary rocks?Biochemical sedimentary rocks are formed from shells and bodies of underwater organisms. The living organisms extract chemical components from the water and use them to build shells and other body parts.Types of biochemical sedimentary rocksThe three basic types of biochemical sedimentary rocks are classified according to their original material:
Limestone (calcium carbonate), coal (carbon), and chert (silica).Thus, we can conclude that biochemical sedimentary rocks formed from the remains of dead organisms.

James looked at a picture of rock layers while studying how scientists determine the ages of rocks. He looked at the variety of layers and understood that the law of superposition indicated something about the rock layer ages. What does the law of superposition indicate?
A. The rock layers can change their position and push younger rock layers under older rock layers.
B. The rock layers can change their position and push older rock layers under younger rock layers.
C. The rock layers on top are the youngest layers and the lower rock layers are the oldest layers.
D. The rock layers on top are the oldest layers and the lower rock layers are the youngest layers.
Answer:The answer would be C.
Explanation:
Law of superposition, a major principle of stratigraphy stating that within a sequence of layers of sedimentary rock, the oldest layer is at the base and that the layers are progressively younger with ascending order in the sequence.

5. Diagram below shows four moon phases observed during July. O First quarter July 8 Moon Last quarter July 24 New Moon July 16 July 31 On which date would the next New Moon occur?
Answer:
August 6th
Explanation:
The next new moon will occur on 15 august. The time period between two new moons is 29.5, which is called a lunatic or synodic month.
What is the moon cycle?The moon orbits the Earth once every 29.5 days, which is known as the moon cycle. Each month, as the Moon progresses through its cycle, which includes a New Moon and a Full Moon, it exhibits eight successive phases. A lunar eclipse occurs when Earth passes in front of the Sun and the Moon, obstructing the Moon's exposure to sunlight. The lunar surface is entirely or partially hidden by Earth's shadow.
Every 27.3 days (a sidereal month), the Moon completes one orbit around Earth, but until it reaches the point in its orbit where the Sun is at the same relative position, the Moon has not yet completed a synodic cycle. This is due to Earth's orbital motion around the Sun.
Hence, the next moon will occur on 15 august.
