Answer:
Options (1) and (2)
Explanation:
The atmosphere is defined as the gaseous envelope that surrounds the earth. It is comprised of various gases which are found to be present at a certain amount, and this amount can also be increased or decreased depending on the processes and activities that take place on the earth's surface.
The atmosphere is helpful because it protects the lives present on earth from the harmful incoming UV radiations emitted from the sun. It also protects the water present on earth from getting evaporated into the atmosphere.
Thus, the correct answers are options (1) and (2).

To make a 25% sugar syrup, we need to determine the amount of water required to dissolve the sugar.
We know that we have 50 grams of sugar, and we want the sugar to be 25% of the total mixture. This means that the remaining 75% will be water.
Let's set up an equation to find the amount of water needed:
Sugar + Water = Total Mixture
50g + Water = Total Mixture
Since we want the sugar to be 25% of the total mixture, we can express it as a decimal fraction:
25% = 0.25
Now we can rewrite the equation as:
50g + 0.25(Total Mixture) = Total Mixture
Next, we want to solve for the amount of water needed. To do this, we'll isolate the Water term:
0.25(Total Mixture) = Total Mixture - 50g
0.25(Total Mixture) - Total Mixture = -50g
0.25(Total Mixture) - 1(Total Mixture) = -50g
-0.75(Total Mixture) = -50g
Dividing both sides by -0.75:
Total Mixture = -50g / -0.75
Total Mixture ≈ 66.67g
Now, to find the amount of water needed, we'll subtract the weight of the sugar from the total mixture:
Water = Total Mixture - Sugar
Water = 66.67g - 50g
Water ≈ 16.67g
Therefore, to make a 25% sugar syrup with 50g of sugar, you would need approximately 16.67g of water.
In figure 33-5, identify the four chambers of the heart. then use them to describe the path through which blood travels in the heart.
Answer:
You did not provide a figure, but you can refer to the attached picture and match it up with your figure.
The heart has 4 chambers. It has the left and right Atrium (plural is atria) and the left and right ventricle.
The blood FROM the body going towards the heart is deoxygenated. It empties into the RIGHT ATRIUM. From there, it goes through the tricuspid valve then empties into the RIGHT VENTRICLE. The right ventricle then pumps the blood up into the pulomonary artery, and goes towads the lungs to be oxygenated. The oxygenated blood then leaves the lungs via the pumonary vein and it empties the blood into the LEFT ATRIUM. From there the blood goes through the bicuspid valve and pours into the LEFT VENTRICLE. The left ventricle pumps the blood up the aorta and from there, it goes to the different parts of the body.
In summary:
BODY ---> RIGHT ATRIUM ---> RIGHT VENTRICLE ---> LEFT ATRIUM ---> LEFT VENTRICLE
Take note though that this is the pathway with regards to ONLY the chambers.

Describe each method of asexual reproduction:
Fission:
Budding:
Fragmentation:
Fission : fission the process where eukaryote cells replicate their DNA and create a new organism with a copy of that DNA.
Budding : a new organism develops from an outgrowth or bud due to cell division. The new organism remains attached as it grows, separating from the parent organism only when it is mature
Fragmentation : an organism is split into fragments. Each of these fragments develop into matured, fully grown individuals that are identical to their parents.
Hope this helps , Danielle xo
Fission is defined as the splitting of a single cell organism into two or more separate daughter cells.
What are the types of fission?Binary fission is of two kinds: Binary fission and multiple fission. Binary fission is most common form of reproduction in that occurs in some single-celled eukaryotes and prokaryotes. For example, amoeba.
Multiple fission is defined as when the organism divides equally into more than two different parts and they develop to form New individuals.
Budding is defined as the formation of an outgrowth (bud) from an organism. Bacteria, yeast, flatworms are the examples of budding.
Fragmentation is a type of cloning where one organism is divided into minor fragments. Once divided, the fragments develop into individual ones which are fully grown.

1. How’s is pressure affected as depth increases?
2. As the sun heats the surface of the oceans, two layers of water result. What separates the layers?
3. How is the temperature affected when (a) the depth increases (b) the latitude increases
4. How is salinity affected?
(A) evaporation increases
(B) freezing increases
(C) melting increases
(D) precipitation increases
5. How is density affected when
(A) the temperature increases
(B) the depth increases
(C) the latitude increases
(D) the salinity increases
1:
At sea level, the air that surrounds us presses down on our bodies at 14.5 pounds per square inch. You don't feel it because the fluids in your body are pushing outward with the same force.
Dive down into the ocean even a few feet, though, and a noticeable change occurs. You can feel an increase of pressure on your eardrums. This is due to an increase in hydrostatic pressure, the force per unit area exerted by a liquid on an object. The deeper you go under the sea, the greater the pressure of the water pushing down on you. For every 33 feet (10.06 meters) you go down, the pressure increases by 14.5 psi.
2:
Two layers of water result would be; Mixed layer and deep water, Also the Thermocline separates them.
Description
A thermocline is a thin but distinct layer in a large body of fluid in which temperature changes more rapidly with depth than it does in the layers above or below. In the ocean, the thermocline divides the upper mixed layer from the calm deep water below.
3:
(A)
The deeper the waters, the lower the temperatures since. The only reason this works is since sunlight isn’t able to penetrate to deeper water due to the fact it gets attenuated bc of diffusion and scattering.
(B)
Temperature of water are lower with increasing attitude due to the fact that the differential angle in which the sunlight usually would hit, would hit earth at a different angle.
4:
(A)
It would increase salinity since, Evaporation of ocean water and formation of sea ice both increase the salinity of the ocean.
(B)
In cold, polar regions, changes in salinity affect ocean density more than changes in temperature. When salt is ejected into the ocean as sea ice forms, the water's salinity increases. Because salt water is heavier, the density of the water increases and the water sinks.
(C and D)
Evaporation of ocean water and formation of sea ice both increase the salinity of the ocean. However these "salinity raising" factors are continually counterbalanced by processes that decrease salinity such as the continuous input of fresh water from rivers, precipitation of rain and snow, and melting of ice.
5:
(A)
Heating a substance causes molecules to speed up and spread slightly further apart, occupying a larger volume that results in a decrease in density. ... Hot water is less dense and will float on room-temperature water. Cold water is more dense and will sink in room-temperature water.
(B)
The water molecules pack together tighter as pressure increases -the pressure increase with depth, due to the weight of the water above, and causes the greatest density changes in seawater with depth (greater than the density changes due to temperature and salinity changes).
(C)
The density decreases
(D)
Increasing salinity also increases the density of sea water. Less dense water floats on top of more dense water. Given two layers of water with the same salinity, the warmer water will float on top of the colder water. ... Temperature has a greater effect on the density of water than salinity does.

Role of primase in replication
1.Primase enzymes are activated by Helicase and form primosome complex.
2. Primase then synthesizes primers- short RNA molecules from ss-template DNA of 4-15 nucleotides long.
3.These primers are recognised by the enzyme DNA polymerase which adds and elonagte by adding nucleotides to the primer.
thus, option B is correct.
What happens to the energy stored in the biomass of an organism when it dies?
Answer:
The energy is recycled

A single pair of goldfish in a aquarium produced a large number of offspring.
These offspring showed variations in body shape and coloration.
The most likely explanation for these variations is what?
(A.) Offspring were adapting to different environments.
(B.) Parent fish had not been exposed to mutagenic agents.
(C.) Offspring were produced from different combinations of genes.
Answer:
C. Offspring were produced from different combinations of genes.
Explanation:
The offspring would not be adapting to different environments as they all live in the same aquarium. There is no mention of mutagenic agents present in the aquarium and that would have had more of an effect on the parents and not the offspring. The parents may have had different sets of alleles which could produce a variety of phenotypes of their offspring.

Answer:
Cones is the correct answer because cone is the female reproductive part
Answer:
Option C, Cones
Explanation:
In Gymnosperm, male microspore and female megaspores are generated in sporangia which are carried by cones/strobili.
Strobili consists of a short stem with leaves known as sporophyll on which sporangia is found. The sporangia producing the male microspore and female megaspore are found on separate cones. The male cone is known as staminate cone and the female cone is known as ovulate cone.
Thus, option C is the correct answer
Is a waste product that uses the most energy to produce
A waste product is a product that is made but isn’t necessarily needed eg. A lightbulb will make light energy but it also makes a waste product heat.
Waste products are nitrogenous wastes excreted from the metabolic processes. Uric acid is a waste product that uses maximum energy to produce. Thus, option B is correct.
What are nitrogenous wastes?Nitrogenous wastes are nitrogen-based products eliminated from the body in various forms like ammonia, urea, and uric acid. Ammonia has one nitrogen and is very toxic.
Urea has two nitrogen and is less toxic. On the other hand, uric acid has four nitrogens and complex molecules although is non-toxic but requires the maximum amount of energy to eliminate four nitrogen.
Therefore, uric acid needs maximum energy.

The two waves in the diagram are occupying the same place at the same time
Answer: by adding the amplitude of the two waves
Explanation:
The question pertains to wave superposition in Physics, demonstrating constructive interference and standing waves when two identical waves intersect in opposite directions, leading to an increase in amplitude and fixed points of no motion (nodes) and maximum motion (antinodes).
The question deals with the concept of wave superposition in Physics, specifically the phenomena known as constructive interference and standing waves, which occur when two waves occupy the same place at the same time.
When two identical waves traveling in opposite directions intersect, they can add up at the same points in space, leading to an increase in amplitude. This process is called constructive interference, resulting in wave patterns called standing waves, characterized by their nodes—points where the amplitude is always zero—and antinodes—points of maximum amplitude. The figures mentioned in the question demonstrate these phenomena. For example, Figure 16.33 illustrates pure constructive interference where the amplitude of the resulting wave is twice that of the individual waves due to their perfect alignment in phase, whereas Figures like 12.1.1 and 5.6.5 show standing wave patterns resulting from the superposition.

first?
O
Electrons in water get released during photolysis
O
Electrons are transported into the electron transport ch
O
ATP is transformed into glucose.
Electrons in chlorophyll become excited.
:)))
Answer:
Electrons become excited
Explanation:
After photons strike the light-absorbing pigment chlorophyll, electrons within the chlorophyll become increasingly excited. Only after this initial excitation do the electrons begin getting transported into the electron transport chain. Electrons in water molecules get released during photolysis, but only after they first become excited. ATP isn’t transformed into glucose until the light-independent stages of photosynthesis.
After photons strike the light absorbing pigment chlorophyll, the electron in that molecule becomes excited. The correct option is D.
What is chlorophyll?Chlorophyll is the term coined to the green pigment used by plants to produce food throughout the photosynthesis process.
Chloroplasts are plant cell organelles that use photosynthetic energy to revert light energy into fairly stable chemical energy.
They endure life on Earth while doing so. Chloroplasts also perform a variety of metabolic functions for plant cells, such as the metabolism of fats and membrane lipids.
Chlorophyll is excited and emits electrons when it absorbs light. These chlorophylls are discovered in photosynthetic units known as Photosystems I and II.
Each unit has a distinct reaction center containing pigment molecules. These molecules absorb different wavelengths of light and emit electrons.
Thus, the correct option is D.
