Look at the reaction below.
H2SO4(aq) + Ca(OH)2(aq).
→ CaSO4(aq) + 2H2O(1)
Which substance is the base in the reaction?
2H20 (1)
H2SO4 (aq)
CaSO4 (aq)
Ca(OH)2 (aq)
Answer:
Ca(OH)2 (aq)
Explanation:
The balanced neutralization reaction i.e. a reaction between an acid and a base, in this question is given as follows:
H2SO4(aq) + Ca(OH)2(aq) → CaSO4(aq) + 2H2O(l)
According to Arrhenius in his definition of acid and base, a base is a substance that dissociates into hydroxide ions (OH-) when in an aqueous solution. In other words, a base increases the concentration of hydroxide ions when dissolved.
In this reaction, Ca(OH)2 releases the OH- (hydroxide ion) that combines with the hydrogen ion (H+) released by the acid, H2SO4, to form water (H2O). Hence, Ca(OH)2 (aq) is the BASE.
Answer:
Ca(OH)2 (aq)

Does the shadow tell you that the girl is translucent, transparent, or opaque? What inference can you make? also explain it
Subject Science
Answer: Well, shadows are visible to us because they are darker than the light around them. When an object is translucent it allows a lot of light to pass through. This amount of light makes the shadow very light and similar in color to the original light source.Why do translucent and opaque materials form shadow? Answer: Translucent and opaque materials form shadow because translucent objects block some light and opaque object block the light completely.A shadow appears the side of the objects furthest from the light source. * An opaque material makes a dark shadow. * A translucent material makes a faint shadow. * A transparent material cannot make any shadow. so it translucent
hope this helps have a nice day❤️

How are ATP molecules important in plants?
Answer:
D
Explanation:
ATP molecules are important in plants as ATP molecules provide energy for the synthesis of carbohydrates.
What are the functions of ATP molecules?Adenosine triphosphate is an organic compound that provides energy to drive many processes in living cells, such as muscle contraction, nerve impulse propagation, condensate dissolution, and chemical synthesis.
Adenosine triphosphate (ATP) is the source of energy for use and storage at the cellular level. The structure of ATP is a nucleoside triphosphate, consisting of a nitrogenous base (adenine), a ribose sugar, and three serially bonded phosphate groups.
Adenosine triphosphate (ATP) are energy-carrying molecule found in the cells of all living things. ATP captures chemical energy obtained from the breakdown of food molecules and releases it to fuel other cellular processes.

Which makes a bigger difference: a 100 kg increase in the mass or a 100 meter/sec rise in velocity?
An increase in mass of 100 kg. No, it is not true that an object moves faster quickly the less mass it has, as your example demonstrates very clearly. Another illustration: a snail moves more slowly than a rocket but weighs much less. Thus option A is correct.
What mass makes a bigger difference compare to velocity?The heavier (denser) object will fall quicker if two identically sized but made of different materials objects are present. This is because both objects will experience the same drag and buoyancy forces, but the heavier object will experience a stronger gravitational pull.
The less an object accelerates when a certain force is applied, the more mass it has. For instance, the acceleration is halved for a given force when the mass of an object is twice.
Therefore, a 100 kg increase in the mass. No, as your example clearly shows, it is not true that an object travels more quickly the less mass it possesses. Another example: a snail travels slower than a rocket but is considerably lighter.

Answer: Embryo sac is the megaspore mother cell.
Explanation:
The bisporic embryo sac can be defined as the comprises of the nuclei that is obtained from two units of the megaspore tetrad on the other hand, the tetrasporic embryo sac comprises of four units of megaspore tetrad. The megaspore mother cell undergoes meiosis to produce megaspore tetrad or four haploid megaspores.
Why is the ovum so much bigger than a sperm cell?
1)It already contains all the chromosomes that will determine the zygote's traits.
2)It must store enough food for the growth of the zygote into an embryo.
3)Its big size allows the sperm to locate it better inside the oviduct.
4)A big ega is easier to implant in the uterus after tertilization.

surface tensions of three different liquids. Which event could be a source of
error?
A. The air temperature varied when someone opened a window.
B. The liquids that spilled over the edges could mix on the table.
C. The vials were made of the same material,
D. The vials were different shapes.
Answer:
D
Explanation:
just did it
The vials were different shapes is the event could be a source of error. Hence option D is correct.
What is surface tension?Surface tension is defined as the tendency to reduce surface area produced by the tension of a liquid's surface film due to the attraction of the surface layer's particles to the liquid's bulk. Cohesive interactions between the liquid's molecule's cause the surface tension to develop. The molecules at the center of the liquid are surrounded by other molecules on both sides.
The forces that bind molecules of the same type together are known as cohesive forces. For instance, cohesive forces between molecules allow liquids to be kept in open containers. Adhesive forces are those that compel distinct types of molecules to come together. For instance, these pressures induce liquid drops to adhere to window panes.
Thus, the vials were different shapes is the event could be a source of error. Hence option D is correct.

Maggots can be used to help predict PMI for a body discovered
hidden among the tall weeds of field
twenty years after death
buried in a deep wet grave
on an ice flow off the Alaskan coast
Answer:
The answer is A, hidden among the tall weeds of field.
Explanation:
Maggots can no longer grow on a body that died 20 years ago. It would have dried out, making it a bad habitat.
It can't be buried in a deep, wet grave, because it would be hard for flies or maggots to get that deep into the soil, so they're going to look for easier options.
If a body was found on an ice flow off the Alaskan coast, it is far too cold for flies to lay eggs on the body.
This leaves "hidden among the tall weeds of a field," which doesn't say that the body has dried out, it's probably not too cold, and it's easy accessible to the flies that need to lay eggs.
