Renewable energy resources are those which can be used again and again. This reuse is possible because either they are present in ample amount or they are produced in a very short span of time.
While a non-renewable energy resource cannot be used again and again. Also if they are recreated, they take millions of years which in other way round lead to their depletion.
Based on the above explanation, the classification is as follows -
A. energy obtained from coal --------------> Non Renewable
B. energy obtained from burning plant waste. --------------> Non Renewable
C. energy obtained from water springs inside the Earth. ---------Renewable
D. energy obtained from natural gas.------------Non Renewable
The classification of the energy sources is as follows:
A. energy obtained from coal: Non renewable
B. energy obtained from burning plant waste: Non renewable
C. energy obtained from water springs inside the Earth: Renewable
D. energy obtained from natural gas:Non renewable
What are Renewable and Non renewable energy sources?Renewable energy resources are those energy sources that are gotten from natural materials which can be used and reused again. Examples include water, soil and plants.
Non renewable energy resources are those energy sources that are artificially gotten and they can't be renewed. Examples include coal, oil,steel aluminium.

The speed of sound through water is 1400 m/s. Which of the following could be the speed of a sound wave through air?
Answer is A. 430 as the speed of sound in water is 1498 m/s but the question has taken an approximate of 1400 m/s
The expected speed of sound in the students' colder-than-usual school room would be lower than the accepted room temperature value of 346 m/s, and much lower than the speed of sound through water.
Explanation:The speed of sound through air varies with temperature and the typical value at room temperature (20°C or 68°F) is 343.5 m/s. This value decreases when the air is colder. Since the accepted speed of sound at room temperature air is 346 m/s, and the school is colder than usual, the speed of sound in the school's room would be expected to be less than 346 m/s, certainly lower than the speed of sound through water which is about 1482 m/s. When the students use standing wave patterns in their lab procedure, they would find a speed lower than the standard 346 m/s due to the lower temperature of their environment.
The accepted speed of sound in room temperature air is 346 m/s. However, in the question, it is mentioned that the speed of sound through water is 1400 m/s.
Since sound travels faster through solids and liquids than through gases, we can conclude that the speed of sound through air will be less than 1400 m/s. Therefore, none of the speeds listed in the options could be the speed of a sound wave through air.
Anoles are a family of lizards found throughout the Americas. Green anoles, Anolis carolinensis, are native to a specific area of Florida. In this area, the primary territory of green anoles was once along the ground and in low-level branches. However, the introduction of brown anoles, Anolis sagrei, from Cuba forced green anoles to shift their territory to the tops of trees. The branches at the treetops are smoother and thinner than those close to the ground. Over time, the toe pads of the green anoles have become larger and stickier.
What is the best explanation for the change in green anoles' toe pads?
A.
Some individuals in the green anole population had mutations that helped them survive and reproduce in the new conditions, so their genes were passed on to the next generation.
B.
Gene flow between the green and brown anoles provided the green anoles with traits that helped them survive and reproduce, and those traits were passed on to the next generation.
C.
The feet of the green anoles became larger and stickier as they used them, which helped the green anoles to better survive, reproduce, and pass the trait on to the next generation.
D.
The change in conditions caused mutations in green anoles that gave them beneficial traits for survival and reproduction, and those mutations were passed on to the next generation.
The answer is; A
The mutation occurs in the population at low rates. However, if these mutations are advantageous, they are maintained in the population and passed on to next generations. This way, the frequency of the mutated alleles increase with each generation. This is how gene change occurs and natural selection.
The correct answer is (A)
Some individuals in a large population are mutated and the mutation was successful as it helped the population to to survive in a better way. The frequency of mutated population started reproducing and was passed on to the next generations. The frequency of mutated population increases with each generation. Some individuals in the green anole population had mutated and that helped them to survive and they successfully reproduced and the trait was passed on to the next generations.
How does a diversity of organisms increase the chances that some will survive a major change in environment ?
This can be explained with an example.
Let’s lake an example of two species 1 and 2.
Species 1 has a wide genetic diversity due to which organism are also diverse in phenotype. Their phenotype are:
Black, dark brown, brown, dark red, red, light red, pink, skin color.
From left to right organism are becoming less adapted to high temperature relatively.
For species 2: This species has less genetic diversity and its phenotypic diversity is as follow:
Black, red, Skin color.
From left to right organism are becoming less adapted to high temperature relatively.
Now if there is the sudden high temperature in the environment; 4 Types of phenotype will survive are black, dark brown, brown, dark red.
While there will only two types of organism in specie 2 which will survive are black, red.
So that’s how the diversity of organisms increase the chances that some will survive a major change in environment.
Plants absorb water from the soil through their roots. _______ of this water is used for photosynthesis; _______ of this water evaporates into the air through transpiration. A. Some; most B. None; all C. All; none D. Most; some
A. I need to make this 20 characters long so yeah
Plants absorb water from the soil through their roots. Some of this water is used for photosynthesis; Most of this water evaporates into the air through transpiration. Therefore, option (A) is correct.
What is transpiration?Plants absorb water from the soil through their roots, and some of this water is used for photosynthesis, while most of this water evaporates into the air through transpiration. Transpiration is the process of water movement through a plant and its evaporation from aerial parts, especially from the leaves and stems.
It helps plants to absorb nutrients from the soil and transport them to the rest of the plant. The process of photosynthesis occurs in the leaves, and water is one of the essential components needed for this process. Therefore, only some of the absorbed water is used for photosynthesis, and the remaining water is released into the atmosphere through transpiration.

Elephants exhibit herding behavior. When they travel, the oldest and largest members often travel in the outer edges of the group. Why is this important to the survival of the species
Answer:
Elephants do not have many offspring, therefore they need to protect them from predators, by the older and larger members of the herd travelling on the outer edges, the young are more protected from being hunted by predators. This is not a means to enhance mating or about food, it is also not just a mere method of organizing themselves either; by travelling this way they protect the survival of the herd and species as a whole.
Explanation:
How does a cell separate itself from its environment and still allow materials to leave and enter the cell in order to maintain homeostasis?
ah! All thanks to the cell membrane!
The cell membrane contains phospholipids that are amphiphilic (polar - water attracting and non-polar - water repelling) in nature. That's why the cell membrane allows non-polar materials to pass through but not polar materials. (if you're learning junior science you really don't need to know this!) The polar materials require proteins found on the cell membrane called protein channels or carrier proteins to pass through. (their names are pretty self-explanatory!)

Living organisms use osmoregulation to balance solute and water concentrations in their cells, tissues and organs. Many marine organisms have internal solute concentrations that are similar to their environment. However, this is not typically true of freshwater and terrestrial organisms. What is likely to happen to the cells of a marine plant if placed in a freshwater environment?
If the marine plant is placed in a freshwater environment, then the cells will undergo plasmolysis.
The plants found in the freshwater surroundings are adjusted for osmoregulation in hypotonic environments. If one place this type of plant in a marine environment, that is, one with a greater concentration of dissolved salts, then the environment is considered as hypertonic environment. The cells of the plant will lose water and will go through the process of plasmolysis.
The Cell will burst or swell due to the large amount of water enters in plan call.
Explanation:The marine plant cell is hypertonic compared with fresh water. So water will enters the cell trough osmosis.Osmosis is a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one.The cell will swell because large quantity of water enters the cell.what kind of cell is this

Kinases and cyclins are internal factors that A. cause apoptosis B. control the cell cycle C. cause cancer cells to break away D. prevent mitosis
B. control the cell cycle
Kinases and cyclins are internal factors that regulate the cell cycle by ensuring that cells progress through the necessary stages of cell growth and division at the proper times.
Explanation:Kinases and cyclins are internal factors that work in symbiosis to control the cell cycle. Their primary function is to ensure that cells progress through the necessary stages of the cell cycle at the proper times, thus regulating cell growth and division. Specifically, cyclins are a group of proteins that are produced in cells during various stages of the cell cycle. Their levels rise and fall regularly, linked with the progression of the cell cycle. Kinases are enzymes that transfer phosphate groups from ATP to proteins in a process called phosphorylation. This process aids in the regulation of the cell cycle. Together, the cyclin-dependent kinases (CDKs) and cyclins form a complex that helps orchestrate cell division.

Circular motion includes all curved paths, not just movement in full circles
Answer;
The above statement is true
Explanation;
-Circular motion is a movement of an object along the circumference of a circle or rotation along a circular path. It can be uniform, with constant angular rate of rotation and constant speed, or non-uniform with a changing rate of rotation.
When an object moves in a circle at a constant speed its velocity (which is a vector) is constantly changing. Its velocity is changing not because the magnitude of the velocity is changing but because its direction is.

C.
The shape of the planet’s orbit will change from elliptical to circular.
D.
The planet’s orbital path will become smaller and its orbital period will increase.
E.
The planet will begin to orbit the star in the opposite direction.
D. The planet's orbital path will become smaller and its orbital period will increase.
The more gravity an object has, the more it will pull objects.
Answer:
The correct answer will be option D.
Explanation:
Planets orbit around the Sun (star) due to the gravity of this star which pulls down them around it. This gravity is the vital force which maintains the elliptical path of their orbit.
If this force of gravity will change it will affect the celestial bodies revolving around it like a planet as this force of gravity is directly proportional to mass and inversely proportional to the distance between them.
According to the question if the gravity of the star increases it will change the orbital path of the planets as they will be more pulled towards the sun which will decrease the distance between the star and planet and the orbital path will become smaller and the orbital period will increase.
Thus, option D is the correct answer.

A. All will have both red and white flowers.
B. Half will have red flowers and half will have white flowers.
C. All will have red flowers.
D. All will have pink flowers.
The correct answer is: A. All will have both red and white flowers.
If camellia plant with red flowers (RR) is crossed with a camellia plant with white flowers (WW), then
P: RR x WW
F1 generation: RW RW RW RW
This means that all of the offspring will have both colors. Codominant means that red and white are equally dominant (both expressed).
In a cross between camellia plants homozygous for red and white flower alleles which are codominant, all offspring will have both red and white flowers visible.
Explanation:In camellia plants, flower color is controlled by a single gene with codominant alleles. The red (RR) and white (WW) flowers represent plants that are homozygous for the red and white alleles respectively. When these plants are crossed, the offspring receive one allele for red and one for white from the parent plants. As they are codominant, both alleles will express themselves, resulting in a phenotype where both red and white are visible. Therefore, the correct answer is A.
