Answer:
It is 25% less
Explanation:
That is all i can say
A close comparison of the 20% solution to the 45% solution shows that the 20% solution is actually less than 50% of the 45% solution.
Arithmetically, you discover that the 20% solution is 25% or 0.25 (45% - 20%) less than the 45% solution.Comparatively, you can compute that the 20% solution actually represents 44.4% or 0.444 of the 45% solution (20% x 45%). The same result can be obtained by first dividing 20% by 45% and then multiplying the resulting dividend by 100.Thus, the result of the comparison shows that there is more sugar in the 45% solution than there is in the 20% sugar solution.

Which is one event that may lead to Primary succession? clear-cutting climate change volcanic eruption introduced species
Answer:
(c)volcanic eruption
Explanation:
An event that may lead to primary succession is volcanic eruption.
Primary succession happens when pioneer organisms colonize an area that holds no life before. It usually happens when a new land is formed or when a bare rock becomes exposed to life.
When volcanic eruption happens, new rocks are formed from the molten magma and these rocks provide a surface that can be colonized by pioneer species such as lichen.
From there, the successional process continues with time until a stable community is formed, all other things being equal.

At which stage of development does the embryo implant in the uterus?
Answer:
Blastocyst stage
Explanation:
A baby undergoes different stages of development before they become fully matured. It all begins with the process of fertilization which involves a sperm cell coming in contact with an egg.
After a successful fertilization, the fertilized egg travels down to the uterus where it undergoes series of cell division till it becomes a stack of arranged cells known as the blastocyst.
During the blastocyst stage, the embryo fastens itself to the edge of the uterus, this process is known as implantation.
Hence, the embryo implants in the uterus during the blastocyst stage.

Explanation:
All fish nitrogen into the water as ammonia and organic nitrogen. These chemicals are byproducts of their metabolism and respiration.
Answer:
The correct answer would be - release/excretes.
Explanation:
In ponds, rivers, or similar ecosystem nitrogen cycle is completed with the help of the fishes. In this ecosystem, the nitrogen cycle initiates with the eating plants or fish food by the fishes and performs metabolism and cellular respiration which produces byproduct ammonia and organic nitrogen as animal waste.
This waste is released or excreted by the fish in the water where the beneficial bacterium helps in restoring nitrogen back to the atmosphere by breaking these wastes.
Students in a science class were asked to investigate how missing or damaged

At what rate does the cell wall need to break down its carbohydrate structure to
meet the high energy needs of the cell?
Answer:
At what rate do the mitochondria of the cell need to convert glucose to usable
energy molecules to meet the high energy needs of the cell?
Explanation:
Organelles are organ-like structures found in cells. The are responsible for the specific actions carried out by each cell. Each organelle has its own specific role to play. However, missing or damaged organelles can have effects on the cells.
Mitochondria are organelles found in cells of all eukaryotic living organisms e.g animal, plants as they are responsible for the synthesis of energy in form of ATP. Since the cells being investigated in this question is a MUSCLE CELL, which is only found in animals, then an appropriate organelle must be investigated.
The appropriate to be asked to know if muscles cells are functioning properly is: At what rate do the mitochondria of the cell need to convert glucose to usable energy molecules to meet the high energy needs of the cell?.
Note that, other options are incorrect because muscle cells do not have chloroplast and cell wall, while ribosomes are not site for glucose production.

WHAT DO SCIENTIST DO WHEN THEY RUN AN EXPERIMENT
In aquatic ecosystems, phytoplankton and other photosynthetic organisms appear in the upper layer of the water, but not deeper layers. Which statement explains this distribution?
ANSWER :
The deeper layers are too dark for photosynthesis to occur.
Explanation:
Photosynthesis is a unique process to autotophic organisms. It involves the use of light energy from the sun to manufacture organic molecules (food). As the phenomenon implies i.e. PHOTO - LiGHT, light is an unnegotiable requirement for photosynthesis to take place. Autotrophs are able to perform this process because they contain pigments (Chlorophyll) that can trap energy from sunlight.
In an aquatic ecosystem, phytoplanktons and other photosynthetic organisms like aquatic plants are the autotophic organisms. They are found in the upper layer of the water so that they can reach light from the sun. The light from the sun cannot travel deep down the water making the deep parts of the ocean be deprived of light.
This is the reason why photosynthetic organisms cannot be found in the deep parts of the water as they will be unable to have access to the light from the sun in order to perform photosynthesis.

How does an area's weather differ from the area's climate?
Weather refers to the short-term atmospheric conditions, such as temperature, precipitation, humidity, wind speed, and cloud cover, that occur in a specific area over a short period of time, typically days or weeks.
Climate, on the other hand, refers to the long-term average weather patterns observed in a particular region over a period of decades to centuries.
Weather is the day-to-day variation in atmospheric conditions, including temperature, humidity, precipitation, wind speed, and cloud cover. It describes the current state of the atmosphere at a specific location and can change rapidly. For example, one day may be hot and sunny, while the next day may be cloudy and rainy. Weather conditions are influenced by various factors, such as air pressure systems, temperature gradients, and local geography.
Climate, on the other hand, represents the average weather patterns and conditions observed in a region over a long period of time. It is determined by factors such as latitude, elevation, ocean currents, and prevailing winds. Climate provides a broader perspective and encompasses the typical range of weather conditions experienced in a particular area. It takes into account long-term trends, seasonal variations, and averages of weather parameters.
While weather can change from day to day or even hour to hour, climate reflects the long-term patterns and trends in weather. For example, a region with consistently high temperatures and low rainfall throughout the year would have a hot and arid climate, regardless of occasional variations in daily weather conditions.
In summary, weather describes short-term atmospheric conditions, while climate represents the long-term average weather patterns observed in a specific area.

during a rainy spring, where are you most likely to find surface runoff
Answer:
there is only one surface in which we can run off in rainy season and that is room
Explanation:
steffie matt
Answer:
On a sloped parking lot
Explanation:
Surface runoff can be referred as the flow of water, that occurs when the excess water flows from the storm water, melt water, flood, rain streams and rain fall. The fast moving water current takes along with it superficial layers like surface and sub- surface layers of soil. Hence, causes water erosion of soil. The slope parking lot will favor, surface runoff more likely than in a grassy prairie, mulched flower bed, or in a sand pit because the slope will provide a surface for free flow of water. There are chances that water gets absorbed by the soil in the grassy prairie, mulched flower bed and sand pit. Whereas the slopy surface of parking lot will not allow the water retention by soil, instead will accelerate the flow of water.

The production and transmission of hormones in the endocrine system is MOST similar to which scenario?
Answer:
You type a text message, which your friend shows to a third party, who reacts to it.
Explanation:
Copied from google.
When a message is shown to a friend who shows it to another person.
What is the endocrine system?
A group of organs called glands makes up your endocrine system. These glands, which may be found all over your body, produce and emit hormones.
Hormones are substances that communicate with your organs, skin, muscles, and other tissues through your blood to coordinate various bodily activities. These messages instruct your body on what to do and when.
The level of hormones in your blood is regularly monitored by your endocrine system. In order to transmit the message, hormones send their messages by locking them into the cells they intend to reach.
When your hormone levels increase, the pituitary gland signals other glands to stop manufacturing and releasing hormones. The pituitary gland has the ability to tell other glands to manufacture and release additional hormones when levels fall below a specific threshold. Homeostasis is a mechanism that functions similarly to your home's thermostat. Almost every process in your body is impacted by hormones.
Therefore, it is like the scenario where a message is shown to a friend who shows it to another person.

Bone does not amplify sound during speaking is _____________________
Answer:
Bone is a solid tissue, which resists a high impact of forces in its major axis.
The function of this fabric is not to transmit sounds, since it does not provide the elasticity, and the necessary elongation that is needed to generate the rope effect as in the case of muzzle cords.
Explanation:
The more rigid and less elastic the fabric is, the less sound it will transmit.
Sound strings, or mouth strings, are those that tighten, are flexible and resonate with different vibrations, in the case of bone tissue, sound vibrations are not influenced in their conformation because they do not have the ability to transmit them. .
The bone tissue, transmits impact forces or high newton levels, does not fulfill the function of transmitting vibrations and emitting sounds in terms of this type of vibrations and their frequencies.
which of the following is most consistent with the modern theory of evolution
The correct answer is Parents pass their physical traits to their offspring; those offspring with traits that help them survive in their environment are able to reproduce.
Explanation:
The modern theory of evolution explains the mechanisms that make organisms change. One of the main ideas this theory proposes is that organisms with traits that help them survive or reproduce have higher chances to pass their genes and traits to new generations. This mechanism makes certain traits to be favored and contributes to the evolution of organisms because after multiple generations certain traits will prevail while others will be eliminated.
Moreover, this theory specifies genes in an organism are not acquired or modified during its life but these are the results of the traits passed to the organism by its parents and evolution occurs only after a long time or multiple generations. According to this, the first option is the correct one.
