The hypothesis will state as follows: IF the concentration of acid increases, THEN, the amount of limestone dissolved will also increase.
WHAT IS A HYPOTHESIS?
A hypothesis is a crucial part of the scientific method. It is a testable explanation of an observation or a proposed answer to a scientific question. A hypothesis, which must be testable via experimentation, can either be accepted or rejected depending on the outcome of the experiment. A hypothesis is an IF, THEN statement that must include the independent and dependent variables of the experiment i.e. it must show how the dependent variable (effect) is affected by the independent variable (cause).In this case regarding the dissolution of limestone with respect to different concentrations of acid, a possible hypothesis will state as follows:
"IF the concentration of acid increases, THEN, the amount of limestone dissolved will also increase".

The cell membrane is primarily made up of fats called triglycerides.
True
False
Answer:
True.
Cause Triglycerides have glycerol and three fatty acids make them fats
The plasma membrane is primarily made up of fats called triglycerides. The statement is true.
What is the composition of plasma membrane ?Plasma membrane composed of lipid, carbohydrate and protein.
Lipids are mainly phospholipids which forms the fabric of the membrane, which form the lipid bilayer structure.
phospholipid molecules are amphiphilic in nature, as it has hydrophilic head or water loving region at the outer side and hydrophobic or water hating region at the inner side of the membrane.
Proteins are mostly Peripheral proteins located at the outer or inner regions of phospholipid bilayer , another type of proteins are intrinsic and extrinsic proteins.
Cholesterol is a fat molecule which is folded between the hydrophobic tails of phospholipid bilayer.
Carbohydrates found as a conjugated form either attached with lipid or protein like glycolipid or glycoprotein.

seeds
answer is seeds
when you hear angiosperms think fruit
Angiosperms reproduce using seeds. Therefore, option (D) is the correct answer.
What type of seeds do angiosperms have ?Angiosperms are plants that blossom and produce fruits that contain their seeds. With around 300,000 species, they are the most numerous and diverse group within the kingdom Plantae. Approximately 80% of all known extant green plants are angiosperms.
Varied plants are angiosperms. They have leaves, stems, and roots. Angiosperm seeds are found in a flower, as opposed to gymnosperm seeds found in conifers and cycads. Angiosperm ovaries, which are typically found in flowers, are where fertilized angiosperm eggs turn into seeds.

Fracking uses highly pressurized fluids, such as water mixed with sand and chemicals, to drive open cracks that exist in underground rock. Which statement best describes an environmental consequence of this process?
A. Chemicals added to the liquid can contaminate groundwater.
B. Wastewater is contaminated with oil and becomes sludge in landfills.
C. Water vapor is released into the air, which is considered a greenhouse gas.
D. Heavy metals are released into surrounding soil, poisoning local vegetation.
Answer:
Option A, Chemicals added to the liquid can contaminate groundwater, this statement best describes an environmental consequence of this process.
Explanation:
Fracking is a process of digging fossil energy sources, which need a lot of water and uses local water resources. It is drawn with high-pressure water, sand and elements, creating high pressure to block the porous rock and discharge gas. The spill itself stops energy from the drilling position, and may even make earthquakes, mainly due to the pumping of overflowing wastewater into porous rock types such as limestone. The most significant result of water distortion is on groundwater.To learn more about fracking, refer:

explain how the difference in diameter is responsible for the process that occurs in the malpighian body
Answer:
Explanation:
Malpighian body is made up of the glomerulus and the Bowman's Capsule. The glomerulus is a network of capillaries that receives blood from the afferent arteriole and gives it further to the efferent arteriole. From the glomerulus, the component of blood diffuse into the Bowman's Capsule through the endothelium and basement membrane of the glomerulus and the epithelium of Bowman's Capsule.
The blood comes into the glomerulus through which it is diffused into the Bowman's capsule. Only the smaller solute molecules and water is allowed to pass through the membranes while the blood cells are retained within the glomerulus. Hence, the Malpighian Body allows the filtration of blood so that the waste can be separated from the blood. The filtrate further moves to tubules where fine reabsorption and secretion takes place. Both the kidneys produce approximately 180 liters of filtrate every day.
The difference in diameter is responsible for the process that occurs in the malpighian body as - it forms some obstruction to blood flow, which results in higher pressure in the glomerular cavity.
Malpighian Body is a structure located in Nephron in the urinary system that helps in ultrafiltration of blood. It consists of a glomerulus and its surrounding Bowman's capsule.
There are two main arteries in the Malpighian body of blood vessels
one entered for filtration, called afferent arteriole.one leaving the structure after filtration called efferent arteriole.Differences in diameter provide for the increased blood pressure in the glomerulus for ultrafiltration.The afferent arteriole has a larger diameter, which leads to more blood would flow into the efferent arteriole, which is of a smaller diameter due to this causes more blood pressure or hydrostatic pressure in the glomerulus.Thus, the correct answer is - it forms some obstruction to blood flow, which results in higher pressure in the glomerular cavity.

9) One difference between carbon-12 ( 2C) and
carbon-14 (CO) is that carbon-14 has
A) two more protons than carbon-12.
B) two more clectrons than carbon-12.
C) two more neutrons than carbon-12.
D) A and C only
E) B and C only
Answer:
C
Explanation:
this is because that Carbon 12 has 6 protons and electrons and the same goes for Carbon 14 so Choice A and choice B can't be answers so D and E arent equivalent too that means Choice C can be the appropriate answer.
further more explanation:
it's also Choice C because both carbon atoms are neutral which means that the number of protons and the number of electrons are the same so that leaves us with neutron and we get the neutron number by subtracting the mass number with the proton number so let's go on shall we!
for carbon 12= 12-6=6
for for carbon 14=14-6=8 which means the best alternative is Choice C.

Inorganic compounds include carbon dioxide, oxygen, water, and most ionic compounds.
True
False
Answer:
[tex]{ \underline{ \sf{true}}}[/tex]
Explanation:
because they chemically decompose
It is true that inorganic compounds include carbon dioxide, oxygen, water, and most ionic compounds.
What are inorganic compounds?Any substance in which two or more chemical elements usually other than carbon are combined, almost always in definite proportions, is an inorganic compound.
When carbon is bound to hydrogen, the compound is classified as organic.
Organic compounds are distinguished by the presence of carbon atoms. Most inorganic compounds do not contain carbon atoms.
Water, sodium chloride (salt), sodium bicarbonate (baking soda), calcium carbonate (dietary calcium source), and muriatic acid are examples of common inorganic compounds (industrial-grade hydrochloric acid).
Inorganic compounds are characterized by high melting points and varying degrees of electrical conductivity.
Thus, the given statement is true.

essay on atoms molecules and matter
Answer:
Atoms are typically made up of three main parts: protons, neutrons and electrons. Think of the protons and neutrons as together forming a “sun”, or nucleus, at the center of the system. The electrons orbit this nucleus, like planets. If atoms are impossibly small, these subatomic particles are even more so.
Molecules are groups of atoms clumped together by chemical bonds. They are also distinguished from ions by their lack of electrical charge.
H20 is a molecule, N2 is a molecule even O3 is a molecule.
Matter is basically anything that takes up space and that has mass. All physical objects have matter. The original stated of matter are solid, Liquid, And gas.
