Which statement best describes the position of a coastal area during a low
tide?
A. It is on a side of Earth that is perpendicular to the Moon.
B. It is on the part of Earth that is experiencing nighttime.
C. It is on the part of Earth that is experiencing daylight.
D. It is on a side of Earth that faces the Moon directly.
Answer:
A is the correct answer
Explanation:
Moon pulls the ocean upwards causing tides
The position of a coastal area during a low tide is: it is on a side of Earth that is perpendicular to the Moon.
What happens during low tide?Whenever the absolute bottom, or the box, arrives at a coast, the coast encounters a low tide. Envision the sea is molded like a ball pointing at the moon. The football's sharp closures address the pieces of the Earth encountering elevated tide and the ball's level sides are the pieces of the earth encountering low tide.
Thus, option A is correct.

In what way does the shape of a molecule affect how the molecule is
involved with living systems?
OA. It determines the weight of the molecule.
OB. It determines how the molecule functions.
O C. It determines oxidation states present in the molecule.
OD. It determines what elements are in the molecule.
Answer:
B
Explanation:
I'm not 100% sure, but B seems like the most likely answer because the shape of a molecule usually is a major factor in how molecules interact with each other.

It took 380,000 years for electrons to be trapped in orbits around nuclei, forming the first atoms.
These were mainly helium and hydrogen, which are still by far the most abundant elements in the universe. Present observations suggest that the first stars formed from clouds of gas around 150–200 million years after the Big Bang. Heavier atoms such as carbon, oxygen and iron, have since been continuously produced in the hearts of stars and catapulted throughout the universe in spectacular stellar explosions called supernovae.

In an ecosystem, the correct order for the food chain is grass, antelope, lion.
What is an ecosystem?Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.There are different types of ecosystems present.

A whale is swimming in the ocean. It communicates with another whale by sending out a sound. Which of the following best
describes how the sound gets to the other whale?
A.
All of the sound absorbed by water changes to heat before getting to the other whale.
В.
The sound is transmitted through water until it reaches the other whale.
C.
All of the sound is diffused in
the water until only a faint sound reaches the other whale.
.D
The sound is reflected in the water before it gets to the other whale.
Answer:
A.
The sound is transmitted through water until it reaches the other whale.
Explanation:
When one whale makes a sound, the sound is transmitted through water until it reaches the other whale. The sound causes a ripple-like effect in the water, producing waves that travel in the water. The waves are heard in all directions. This is why humans can hear the sounds animals make underwater.
The statement which best describes how the sound gets to the other whale is that all of the sounds absorbed by water change to heat before getting to the other whale. Thus, the correct option for this question is A.
How sound may transmit from one place to another?The transmission of sounds is generally carried out through a medium in the form of waves. These sound waves involve the pattern of disturbance caused by the movement of energy.
In an aquatic environment, when one whale successfully constructs a sound, the sound is effectively transmitted through the medium that is known as water.
It remains in the form of waves until it reaches the other whale. The sound in a waveform provokes a ripple-like effect in the water and travels in the water. The waves are effectively heard in all directions.
Therefore, the correct option for this question is A.

Answer:
During exercise, heart rate can rise dramatically, from a resting rate of 60–80 beats per minute to a maximum rate of about 200 for a young adult. While you are running, blood flow is diverted toward tissues that need it most. For example, muscles in the arteries in your legs relax to allow more blood flow.

How do you know if a compound is covalent
Answer:
Compounds containing two elements (binary compounds) can either have ionic or covalent bonding. If a compound is made from a metal and a non-metal, its bonding will be ionic. If a compound is made from two non-metals, its bonding will be covalent.
An ion is when an atom or molecule has an electric change True or False

The elements mercury and bromine are both liquids at room temperature, but mercury is considered a metal, and bromine is considered a non-metal. How can that be? Explain using properties you know of.
Answer:
At room temperature, mercury and bromine are of fluid consistency, it is because their melting or melting temperature is very low, so low that it reaches room temperature.
Compared to mercury and other metals, the more traditional metals have much higher melting temperatures.
On the other hand, bromine is not a metal, since it does not have the ability to oxidize with the presence of oxygen and also does not give up electrons.
Explanation:
Mercury in the periodic table is Hg, and bromine is Br

Many plants in rainforests have leaf tips that come to a point, so precipitation drains off the leaf. This helps to keep the plant safe from harmful germs. Based on this info, what resource is prevalent in a rainforest?
Answer:
rainfall/water
Explanation:
The possession of drip tips by the leaves of plants in the rainforest is a form of adaptation against high rainfall. Without the drip tips on leaves, water will persist on the surface of leaves, and in conjunction with the warm climate, promotes the growth of pathogens such as fungi and bacteria.
Hence, the possession of drip tips on leaves is an indication of the prevalence of water in the rainforest region.

The maximum allowable concentration of Pb2+ ions in water in a local community is 1.51 x 10-8 M. Could a chemist use 2.00 mL of 0.12 M KBr solution on a 5.00 mL sample of tap water to prove through a precipitation reaction that the water supply is safe? Show all work and reasoning
Answer:
The water supply is not safe.
Explanation:
Ionically, the reaction is;
Pb^2+(aq) + 2Br^-(aq) -------> PbBr2(s)
Amount of Br^- reacted = 2/1000 * 0.12 = 2.4 * 10^-4 moles
From the reaction equation;
1 mole of Pb^2+ requires 2 moles of Br^- for complete precipitation
x moles of Pb^2+ requires 2.4 * 10^-4 moles of Br^-
x = 1 * 2.4 * 10^-4 /2
x = 1.2 * 10^-4 moles of Pb^2+
Concentration of Pb^2+ precipitated from 5ml of tap water = 1.2 * 10^-4 * 1000/5
Concentration = 2.4 * 10^-2 M
The amount of Pb^2+ found in the water is greater than the maximum allowable concentration of Pb2+ ions in water in a local community which is 1.51 x 10-8 M. Therefore, the water supply is not safe.

Yes, that is correct!
Explanation:
Answer:
Yes
Explanation:
A covalent bond consists of the mutual sharing of one or more pairs of electrons between two atoms. These electrons are simultaneously attracted by the two atomic nuclei. A covalent bond forms when the difference between the electronegativities of two atoms is too small for an electron transfer to occur to form ions.
