Answer:
10 m/s/s or m/s²
Explanation:
Acceleration can be calculated by using the formula;
a = v - u/t
Where;
a = acceleration (m/s²)
v = final velocity (m/s)
u = initial velocity (m/s)
t = time (s)
In other terms, acceleration (a) can be represented as ∆V/t.
According to this question, a ball accelerates from 10 m/s (u) to 30 m/s (v) in 2 seconds. Hence, the acceleration of the ball is as follows:
a = 30 - 10/2
a = 20/2
a = 10m/s².

What is the
original source of the energy contained in coal?
Answer:
Coal is called a fossil fuel because it was made from plants that were once alive! Since coal comes from plants, and plants get their energy from the sun, the energy in coal also came from the sun. The coal we use today took millions of years to form.

What are the types of vascular plants? How do they reproduce?
crytogams - this type of vascular plant reproduces by spore.
phanerogams - this type of vascular plant reproduces from the seeds, hence also named as seed plants.
Angiosperms - this type of vascular plant reproduces flowers and fruits
Gymnosperms - this type of vascular plant reproduces cones and seeds only.
Answer:
Vascular plants are plants that have roots, stems, and leaves. They have a vascular system that is responsible for the distribution of water and nutrients. This system is made up of the xylem (responsible for distributing the raw sap to the leaves) and the phloem (responsible for transporting the processed sap to the rest of the plant). Within this group we have: pteridophytes (Many plants do not produce flowers. They are also known as cryptogams. They reproduce through spores) and spermatophytes (they are vascular plants that produce seeds and, therefore, are the most evolved).
Explanation:
Vascular plants are those that have a “corm” made up of root and stem (stem and leaves), as well as a conduction system made up of xylem and phloem for transporting water and photosynthates. Pteridophytes are vascular plants that do not produce seeds. Within the vascular plants they are the simplest plants at a structural level, since they do not have the complexity linked to the production of these seeds, which are what allow the sexual reproduction of plants. Spermatophytes are the vascular plants that produce seeds. These seeds generated by the flowers, when they fall to the ground after dispersing, germinate and give rise to a new plant. This presence of seeds that can be spread by the wind or by animals is what has allowed these plant species to colonize the world.
Natural selection will only lead to evolution if it allows for an organism to:
a) Possess advantageous traits
b) Compete for resources
c) Produce offspring
d) All of the above
A ________
is a system formed by the interaction of a community of organisms with
their physical environment
A.Biome
B.Ecosystem
C.Habitat
D.Campground
B. Ecosystem

The climate of Antartica is mostly affected by________ current
A. Warm
B. Cold
C. Neutral
Answer:
A.) Warm
Explanation:
The climate of Antartica is mostly affected by warm currents
Don't be fooled by the question. When you think of Antartica's climate, you associate it with being cold, which is true. But, this question is not asking "What is the climate of Antartica?". It's asking what type of current affects Antartica's climate the most.
Warm currents, primarily caused by global warming, affect Antartica's climate the most.
"The warming of the Antarctic Peninsula is causing changes to the physical and living environment of Antarctica."

Plant material can
increase which of
the following in
soil?
Answer:
Soil is a major source of nutrients needed by plants for growth. The three main nutrients are nitrogen (N), phosphorus (P) and potassium (K). Together they make up the trio known as NPK. Other important nutrients are calcium, magnesium and sulfur.
Explanation:
The best I could do
Through their roots, plants absorb water and mineral nutrients, returning organic matter to the soil through root exudates, litterfall, and roots. Thus, they can increase organic matter in the soil.
What increases soil quality?Through their roots, plants absorb water and mineral nutrients, and they return organic matter to the soil through litterfall, roots, and root exudates.
Avoid over-tillage while preparing seedbeds, and maintain the seedbed as coarse as you can to keep the aggregates big enough to hold gases and carbon. Any organic material input enhances soil quality. Organic matter enriches the soil with carbon while preserving the separation and integrity of the soil aggregates.

Which level has the most number of organisms but the least specific characteristics?
Answer:
Kingdom
Explanation:
Out of all the taxonomic categories, the Kingdom is the least specific, which means it has the least filters.
I like to think of taxonomic categories as filters/sieves. If you put your animals through the Kingdom filter, then all the animals are in that category. if you have a finer sieve, then less animals get through, this goes down all the way to the most specific which is Species.

For a neuron to function, an input of free energy from ATP is required to set up the sodium and potassium ion concentration gradients such that a signal can be propagated down the axon of a neuron without the necessity of ATP. The system could have worked the opposite way. The neuron could have used ATP to move ions across when a signal was being propagated and then allow natural diffusion to return the ions to their respective sides of the membrane. What advantage does the organism have using ATP up front
Answer:
The lack of ATP would slow nerve responses to generate an action potential
Explanation:
Adenosine triphosphate (ATP) is the main source of energy in the cells. Moreover, ATPases are pumps that use ATP in order to transport sodium and potassium ions across the cell membrane and thus create an action potential. In stressful situations (e.g., escape from a predator) the lack of ATP would not allow to develop fast nerve responses, thereby ATP is required during rest periods and the flow of ions is used when is required a fast response.
If I mix red, blue, and green light equally I get white light. Would the same thing happen if I mix the same colors in paint? Why or Why not?
When you mix red, blue, and green light equally you get white light, because in this case all these colours get added. But exact opposite happens in the case of paint. In paint, these colours gets subtracted to form black colour.
In simple words, when we mix paint, all the light falling on the paint gets absorbed. So, it reflects no light and gives black colour. This is because the light that doesn't get absorbed by one pigment gets absorbed by the other one. So, all the light gets absorbed.
