Which event may occur when ocean salinity increases?
mass of water increases
freezing point of water increases
sunlight in deeper locations decreases
amount of dissolved gases in water increases
Answers
Salinity increases on increasing the mass of water.
What is salinity?
Salinity is the saltiness or amount of salt dissolved in a body of water.
When salt is dissolved in fresh water, the density of the water increases because the mass of the water increases. Therefore on increasing mass of water, salinity will increase.Adding salt to water lowers the freezing temperature. Thus salinity will decrease on increasing the freezing point of water.On decreasing the sunlight in deeper locations, salinity will also decrease.On increasing the amount of dissolved gases in water, salinity will decrease.Learn more:

How do changes to the structure and function of proteins affect humans?
Answers
A protein's shape determines its function.
Explanation:
Because form determines function, any slight change to a protein's shape may cause the protein to become dysfunctional. Small changes in the amino acid sequence of a protein can cause devastating genetic diseases such as Huntington's disease or sickle cell anemia.
What needed to be present in marine mud to form fossil fuels?
Answers
Carbon and Hydrogen.
Answer:
Mostly decaying organisms are needed to present in marine mud to form fossil fuels.
Explanation: When organisms and plants died and sank to the bottom of swamps and oceans, brown soil-like materials called peat are formed. Over millions of years, the peat became covered with sand, clay and other minerals and the peat is converted into layers of sedimentary rocks. After a long time, different type of fossil fuels are formed.

Each section of a lab report has its own purpose. 1. Title: expresses the topic of your study 2. Abstract: summarizes your research aims, methods, results, and conclusions
Explanation:
When the speed of the bottle is 2 m/s, the KE is kg m2/s2. When the speed of the bottle is 3 m/s, the KE is kg m2/s2. When the speed of the bottle is 4 m/s, the KE is kg m2/s2. When the speed of the bottle is 5 m/s, the KE is kg m2/s2. When the speed of the bottle is 6 m/s, the KE is kg m2/s2.
instructions
In this part of the experiment, you will be changing the speed of the bottle by dropping it from different heights. You will use the same mass, 0.250 kg, for each trial, so record this mass in Table B for each velocity. Then, calculate the expected kinetic energy (KE) at each velocity. Use the formula KE = mv2,
where m is the mass and v is the speed. Record your calculations in Table B of your Student Guide.
Answers
Answer:
Based on the given instructions, you need to calculate the expected kinetic energy (KE) at each velocity using the formula KE = mv^2, where m is the mass and v is the speed. The mass is given as 0.250 kg.
Table B: Calculation of Kinetic Energy (KE)
Table B: Calculation of Kinetic Energy (KE)
Speed (m/s)Mass (kg)KE (kg m^2/s^2)20.2500.50030.2500.75040.2501.00050.2501.25060.2501.500
To calculate the kinetic energy at each velocity, multiply the mass (0.250 kg) by the square of the velocity.
For example, when the speed of the bottle is 2 m/s: KE = (0.250 kg) * (2 m/s)^2 = 0.250 kg * 4 m^2/s^2 = 1.000 kg m^2/s^2
Perform similar calculations for the other velocities and record the results in Table B.
Answer:
Explanation:mass of the bottle in each case is M = 0.250 kg
now as per given speeds we can use the formula of kinetic energy to find it
1) when speed is 2 m/s
kinetic energy is given as
2) when speed is 3 m/s
kinetic energy is given as
3) when speed is 4 m/s
kinetic energy is given as
4) when speed is 5 m/s

1156 g/L
= ________ kg/mL
Answers
The Answer is 0.001156.
1156 g/L = 1.156 kg/L
Since 1 L is equal to 1000 mL, we can convert kg/L to kg/mL by dividing by 1000:
1.156 kg/L = 1.156/1000 kg/mL
1.156/1000 kg/mL = 0.001156 kg/mL
Therefore, 1156 g/L is equal to 0.001156 kg/mL.

Why is it easier for most metal elements to gain electrons rather than to lose them?
PROPER EXPLANATION
Answers
Because it is easier for metals to shed their valence electrons and form cations for a stable configuration, they have comparatively few chances of acquiring electrons.
The metals usually complete their octet in each reaction. The outermost electron shell often contains more electrons in metals. Metal atoms lose electrons when they interact with other non-metals because the energy of an electron in its outermost shell is very weak.
Metals often have low ionization energy because their electrons are positive in nature. Metals lose their electrons and trade them with non-metals to achieve a stable configuration.

Technique A: Sprayed his corn crop with an insecticide. The insecticide is known to kill all honeybee, butterfly, and moth larvae.
Technique B: Used a genetically modified variety of corn. The plant produces an insecticide which selectively kills only the moth larvae as it feeds on the corn.
Which technique is likely to have less of an impact on the environment?
Technique B because it may help humans who consume corn to fight bacteria
Technique A because it kills a broader variety of insects to protect the corn
Technique B because it preserves the harmless insects and targets only the moth larvae
Technique A because insecticide use is better for preserving the environment.

A.) wavelength
B.) frequency
C.) amplitude
D.) crest
Answers
Answer:
first answer is B second answer is a and third answer is d
Compared to wave A, wave B has a shorter wavelength and lower frequency. So, the correct options of 1, 2 and 3 are B, A and D.
What is Wave?A wave is defined as a propagating dynamic disturbance of one or more quantities that may be periodic, in which case those quantities oscillate repeatedly about an equilibrium value at some frequency.
Frequency and wavelength can be calculated by this formula,
\(v=\lambda f\\v = velocity\\\lambda = wavelength\\f = frequency\)
A wave with a crest that is closer to the baseline has a smaller amplitude. When compressed coiled spring faster but keeps everything else the same, the crest will increase.
Thus, the correct options of 1, 2 and 3 are B, A and D.

Classify matter by the arrangement of its atom?
Please help me understand/anwser too please
Answers
Answer:
Matter can exist in three different states, solid, liquid, and gas, based on the way the atoms and molecules are arranged inside them.
Explanation:
Solid- the atoms are packed together and aren't moving, so nothing can go through them.
Liquid- the atoms are spread out slightly and moving a little, so that's why it's pretty hard to run through the water and yet it's hard to run on top of the water.
Gas- the atoms are spread far away and moving rapidly, that's how we are able to walk without bumping into any of the gases around us, but as we get higher in elevation the atoms are further spaced out and it becomes harder to breathe.

HELP! 100 POINTS! A cinder block is pulled 0.50 meters to the right in 3 seconds. What is the block's average speed to the nearest hundredth of a meter per second (m/s)?
Answers
The average speed of the blocks are 0.36 m/S.
Explanation:
Average speed is defined as the ratio of distance covered per unit time. So if it is said that blocks are pulled to 0.9 m in the right side. This means the blocks cover a distance of 0.9 m from the origin and that distance is covered in 2.5 s. Thus, the average speed can be calculated from the change in speed
with respect to time. As at time t = 0, the speed is
also zero, and at time t = 2.5 s, the speed will be
Speed =
0.9 = 0.36
2.5
Since, in this case, the speed is equal to the average speed of blocks. So the average speed of the blocks will be 0.36 m/s.
2.5
Since, in this case, the speed is equal to the average speed of blocks. So the average speed of the blocks will be 0.36 m/s.
