Which of these is a disadvantage of hydroelectric energy ?
A. Is expensive to build or maintain
B. Has high power plant efficiency
C. Has a long power plant life span
D. Reduces greenhouse gas emissions
Answer:
A. Is expensive to build or maintain
Explanation:
Hydroelectric energy is a type of energy which is generated from the flow of water. In this energy, water is allowed to fall from a certain height on the turbine. The moving of turbine produces energy. The main disadvantage of hydroelectric energy is that it is very expensive and require high amount of money for the construction and maintenance of hydroelectric power plant. The machinery used for the production of hydroelectric energy is very costly.
Wooly mammoths became extinct thousands of years ago while other species of mammals that existed at that time still exist today. These other species of mammals most likely exist today because unlike the mammoths they
Answer:
4. had certain inheritable traits that made them to survive
Explanation:
The options are:
1. produced offspring that all had identical inheritable characteristics
2. Did not face a struggle for survival
3. learned to migrate to a new environment
4. had certain inheritable traits that made them to survive
The correct option would be option 4.
This is law of natural selection at play. According to this law, organisms that are better suited to an environment survive, multiply, and pass their survival genes to their offspring. Those that are weakly adapted to the environment usually fade off the environment gradually.
Hence, other species of mammals exist today most likely because they had inheritable traits that made them to survive the changing environment while mammoths became extinct because they were poorly adapted to changing environment.
What do the Spike Proteins do?
Answer:

Explanation:
Ice cubes float in water because they are less
Answer: Ice floats because it is less dense than the water. Something denser than water, like a rock, will sink to the bottom. To be able to float, an object must displace fluid with a weight equal to its own weight. The fact that ice floats in water is a bit strange, because most substances are denser when they're solids.

What are 3 pros and cons of fracking?
Please help and thank you
Answer:
3 Pros and 3 cons
Explanation:
Pros:
The fracking process has reduced the need of coal in the United States. There is a relatively low amount of water intensity used - Compared to nuclear energy this requires up to 1000 times less energy. Fracking wells are not permanent- Drilling operations eventually stop.Cons:
The clear consequences for Fracking on the environment are not yet known. This process is often known to leak methane. The lower prices for fossil fuels causing more people to use them - This is really bad for the environment.During which stage of a cell's cycle do the replicated chromosomes thicken and

Suzanne has a cat and uses a pet carrier to take her cat to the veterinarian. After a few years, the cat runs away and hides everytime suzanne gets the carrier out. Which beat describes the cats behavior?
Answer:
C. Conditioned
Explanation:
Based on the reaction that the cat is having it seems that the cat has a conditioned response to the carrier being out. This means that the cat has a learned response that is directly associated with a certain stimuli which in this case is the carrier. Since he has a bad experience with the carrier before, he now reacts in a scared manner every time he sees it.

What is one reason why the abundance of angiosperms could have helped small mammals be successful and produce more offspring?
Answer:
The reason why the abundance of the mammals be successful is that it provides food and oxygen for the survival of the mammals.
These plants also attract the mammals which helps in mating of the animals and producing more offspring.
A healthy animal will only lead to the producing more healthy offspring and by getting proper food the animals will produce successful offspring.

• How do each of the representative organisms obtain glucose in order to perform cellular respiration?
• How do each of the representative organisms get rid of carbon dioxide, the waste product of cellular respiration?
• How are the processes of cellular respiration & photosynthesis connected? Use the representative organisms to explain your answer.
complete sentences, please
Answer:
Plants obtain glucose in the process of photosynthesis while animals obtain glucose by eating other organisms.
Explanation:
Plants obtain glucose in the process of photosynthesis while animals obtain glucose by eating other organisms. In plants, carbondioxide is used as a raw material in the process of photosynthesis but also small amount of carbondioxide gas is released during respiration from stomata present on leaves while animals has lungs which helps in the removal of carbondioxide gas from the body during breathing.
Cellular respiration and photosynthesis are opposite to each other. respiration is energy releasing process while photosynthesis is a process in which food is produced.
A. Increased shoot and leaf growth and increased photosynthesis
B. Accelerated CO2 uptake by leaves and increased transpiration rate
C. Decreased water uptake activity in roots and a shutdown of CO2 uptake by leaves
D. Reduced photosynthesis and increased root growth

Describe how natural selection impacts the evolution of organisms
Answer:
Natural selection is the process through which populations of living organisms adapt and change. Natural selection can lead to speciation, where one species gives rise to a new and distinctly different species. It is one of the processes that drives evolution and helps to explain the diversity of life on Earth.

Explanation:
Aerobic respiration will yields 36 ATP molecules and starts with the process of glucose molecules.
What is Aerobic respiration?The respiration in which glucose molecules produces energy in the form of ATP is called aerobic respiration.
The aerobic respiration produces 36 ATP molecules. Fermentation will produce lactic acid. Aerobic respiration consists of three stages such as glycolysis, ETC cycle.
The conversion of fuel, such as fats and sugars, into chemical energy is known as aerobic respiration. Anaerobic respiration, in contrast, doesn't require oxygen.
Therefore, Aerobic respiration will yields 36 ATP molecules and starts with the process of glucose molecules.

Which activity is a method of habitat restoration?
By restoring biotic elements (such as species composition and interactions among species) and abiotic factors (such as soil chemistry, water content, and disturbance) to historical levels, habitat restoration can be achieved. Thus, option A is correct.
What are the important methods in habitat restoration?Reducing tillage, employing more organic fertilizer and pest management, and raising a wider variety of crops, including trees, are always to restore them.
By using these steps, soils can increase their productivity and restore their carbon reserves, allowing countries to feed their growing populations without needing additional land.

An earthquake occurred at 6:35:10 am. At what time did the S-wave arrive at a seismic station 4000 km away?
Answer: Around 6:55:40 Am
Explanation:
The velocity of the S wave may depend on the density of the ground.
The speed can go from 1km/s to 8km/s, with an average velocity of 3.25km/s
Now, we can use the equation:
Velocity = distance/time.
Time = distance/velocity.
We have distance = 4000km
and velocity = 3.25km/s
time = 4000km/3.25km/s = 1230.77 seconds.
now, a minute has 60 seconds, so this is:
1230.77/60 = 20.5 minutes. or 20 minutes and 30 seconds
So the earthquake will reach the seismic station around
6:35:10 + 0:20:30 Am
6:55:40 Am
