A thunderstorm adds freshwater to the ocean as it lowers the density of the water. Thus, option B is correct.
What creates density variations in ocean water?
Differences in temperature and salinity that create density variations in ocean water and salinity refer to how much salt that the ocean water contain, and the temperature became a very important factor because it could determine the amount of water that evaporates.
The term thermohaline circulation is the mixing of hot and cold water from upper surface to the lower surface. This is caused by the temperature and salinity that changes in the water.
It is driven by the density gradient in which the thermohaline circulation begins when the temperature is very cold and ice forms in the sea. The surrounding sea water gets saltier and its density increases and it sinks down.
Therefore, A thunderstorm adds freshwater to the ocean as it lowers the density of the water. Thus, option B is correct.

Which two phenomena are evidence that gravitational forces are attractive? Select two statements.
A. the rise and fall of the tides
B. atoms being held together in a molecule
C. a dropped object always falls toward Earth
D. microwaves passing through the atmosphere into space
Answer:
A. the rise and fall of the tides.
C. a dropped object always falls toward Earth.
Explanation:
Gravity is considered to be a universal force of attraction which acts between all objects that has both mass, energy and occupy space. Therefore, it acts in such a way as to bring objects together.
Additionally, the gravity of earth makes it possible for all physical objects to possess weight.
The two phenomena which are evidence that gravitational forces are attractive includes;
I. The rise and fall of the tides: this is caused as a result of the gravitational force of attraction exerted by the moon on earth.
II. A dropped object always falls toward Earth: this acceleration is due to the gravitational force of attraction between the Earth and the object.
what happens when oceanic crust collides with continental crust at plate boundary
Explanation:
When oceanic crust converges with continental crust, the denser oceanic plate plunges beneath the continental plate. This process, called subduction, occurs at the oceanic trenches. The entire region is known as a subduction zone. Subduction zones have a lot of intense earthquakes and volcanic eruptions.

what are the two strands of DNA
Answer:
The DNA molecule consists of two strands that wind around one another to form a shape known as a double helix. Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups. Attached to each sugar is one of four bases--adenine (A), cytosine (C), guanine (G), and thymine (T). But there are two types of DNA in the cell – autosomal DNA and mitochondrial DNA. Autosomal DNA (also called nuclear DNA) is packaged into 22 paired chromosomes. In each pair of autosomes, one was inherited from the mother and one was inherited from the father.
Extra: Because the two strands of a DNA molecule have complementary base pairs, the nucleotide sequence of each strand automatically supplies the information needed to produce its partner. Before replication can occur, the length of the DNA double helix about to be copied must be unwound.

There are 2 chromosomes.
The two strands are held together by hydrogen bonds between the bases, with adenine forming a base pair with thymine, and cytosine forming a base pair with guanine.
Human cells contain 23 pairs of chromosomes (46 chromosomes in total). Each chromosome is formed by 2 strands of DNA that hydrogen-bonded to each other make the classic DNA double helix (double-stranded DNA).
Which of the following statements about metabolism are true? 1) Catabolism is the process in which complex substances are broken down, yielding a net output of energy. 2) Metabolism is an integrated system in which many of the same reactions participate in degradative (catabolic) and biosynthetic (anabolic) pathways. 3) Anabolism involves the synthesis of polymeric biomolecules and complex lipids from monomers such as fatty acids and nucleotides. 4) All organisms require an external source of energy, such as glucose or sunlight, for metabolic energy.
Answer:
the answer is 1), 2) and 3)
Explanation:
Metabolism can be defined as all the chemical reactions inside a cell that are required to carry out cellular functions (e.g., reproduction, growth, development). The metabolic reactions can be divided into anabolic and catabolic reactions. Anabolic reactions refer to metabolic reactions that require energy in order to construct new molecules from smaller ones (i..e., biosynthesis). Anabolism comprises endergonic metabolic pathways which are fueled by the use of energy (e.g., cellular ATP). On the other hand, catabolic reactions refer to metabolic reactions where larger molecules are separated to form smaller ones. Catabolic reactions are exergonic because they do not require energy (for example, reactions involved in cellular respiration).
What causes the appearance of the Moon to change over time?
A
The orbit of the Earth around the Moon and its distance from the Sun.
B
The Moon's position relative to the Sun and Earth as it revolves around
Sun.
с
The rotation of the Moon on its axis.
The distance of the Moon to the Sun.
D
Answer:
B
Explanation:
The reason we see different moon phases is because of how the sun, earth and moon are relative to each other .
Answer:
As the Moon orbits our planet, its varying position means that the Sun lights up different regions, creating the illusion that the Moon is changing shape over time. The best way of getting to understand the lunar phases is to regularly go out on a clear night when the Moon is in the sky and observe it.
Explanation:
Actually, the Moon rotates in the same period that it revolves, so we always see the same side (the white arrow keeps pointing to Earth). The differences in the Moon's appearance from one night to the next are due to changing illumination by the Sun, not to its own rotation.

Phagocytes often do not recognize bacterial cells with capsules, increasing the likelihood they will survive and cause disease. What other benefits could capsules give bacterial cells?
Answer: Other benefits that a capsules can give to bacteria includes:
--> slowing the penetration of antibiotics or chemicals,
--> it helps bacteria to adhere to surfaces
--> it prevents them from drying out as it contains water components.
Explanation:
Most microorganisms such as bacteria, virus, and parasites, are free living that benefits both plants and animals. The microorganisms that have the ability to cause disease are called pathogens. Infection occurs when pathogens are able to establish itself in a person through the use of its virulent factors. A typical example of virulent factors include the CAPSULES.
Capsules are made up of polysaccharides which lines the outer layer of a bacteria cell envelope. Example of such bacteria includes:
--> Streptococcus pneumoniae,
--> Klebsiella pneumoniae,
--> Haemophilus influnzae, and
--> Neisseria meningitis
These bacteria secrete a capsule around their cell wall which helps to prevent opsonization and phagocytosis by phagocytes of immune system of the host. This helps them to survive and cause disease. Other benefits that a capsules can give to bacteria includes:
--> slowing the penetration of antibiotics or chemicals,
--> it helps bacteria to adhere to surfaces
--> it prevents them from drying out as it contains water components.
The two sounds heard through the stethoscope during a heartbeat are known as lub and dub. If the doctor detects an unusual lub
sound, evaluate which description could explain the atypical sound.
Answer: the description that could explain the atypical sound is known as HEART MURMURS.
Explanation:
The doctor makes use of instruments like the stethoscope to listen to the sounds of the heart while examining a patient. The sound heard in a normal heart beat is described as a "lub" and a "dub" sound.
The "lub" sound, which is called the first heart sound, is associated with closure of the atrioventricular valves at the beginning of a systole and the "dub" sound,which is called the second heart sound, is associated with the closure of the semilunar ( aortic and pulmonary) valves at the end of systole.
HEART MURMURS usually occurs when there are abnormalities of the valves which may occur due to congenital heart defects. It is classified according to when it occurs and these includes:
--> systole murmurs: these occurs during the first heart sound and,
--> Diastole murmurs: these occurs during the second heart sound.
Therefore the description that could explain the atypical sound is known as HEART MURMURS
Answer:
b.) the mitral valve does not close after the systolic phase.

3. Which of the following is NOT a method that has been used to predict earthquakes?
A) Trying to observe precursors such as foreshocks and changes to animal behavior.
B) Watching changes in weather patterns.
C) Using past earthquake patterns.
D) Predicting stress accumulation based on how recently an earthquake occurred.
Predicting stress accumulation based on how recently an earthquake occurred is not the method that has been used to predict earthquakes. The correct option is D.
What is earthquake?Earthquakes typically result from subsurface rock breaking unexpectedly and rapid movement along a fault.
The seismic waves that cause the ground to tremble are brought on by this quick release of energy.
When two chunks of the ground abruptly slide past one another, an earthquake results. The fault or fault plane is the area where they slide.
Erratic animal behaviour, such as fearful or puzzled pets, or birdcalls not typically heard at night, can be a clue that an earthquake is about to happen. Water levels in wells or artesian bores suddenly change.
It hasn't been possible to anticipate earthquakes by basing stress accumulation on how recently an earthquake happened.
Thus, the correct option is D.

If the first trophic level in an energy pyramid receives 1,000 units of energy from the Sun, how much energy is available for the third trophic level?
Answer:
10 units
Explanation:
Energy is transferred from organism to organism in an ecosystem when they feed on one another. However, based on the pyramid of energy, only about 10% of energy is transferred from one organism to another because a bulk of energy (about 90%) has been lost to metabolic activities.
Energy moves from producers to consumers, each occupying trophic levels. If the first trophic level in an energy pyramid receives 1,000 units of energy from the sun,
- 10% of 1000units will be available for the second trophic level i.e. 10/100 × 1000 = 100units
- 10% of 100units will be available for the third trophic level i.e. 10/100 × 100 = 10units
Hence, 10units of energy is available for the third trophic level.
