Answer:
Sedimentary rocks are formed from pre-existing rocks or pieces of once-living organisms. They form from deposits that accumulate on the Earth's surface. Sedimentary rocks often have distinctive layering or bedding. Sedimentary rocks are types of rock that are formed by the accumulation or deposition of mineral or organic particles at the Earth's surface, followed by cementation. Sedimentation is the collective name for processes that cause these particles to settle in place. Sedimentary rocks are made when sand, mud and pebbles get laid down in layers. Over time, these layers are squashed under more and more layers. Eventually, the layers are lithified – turned to rock. Sedimentary rocks can be formed in deserts, lakes, rivers and seas .

Does Natural Selection affect individuals or populations? EXPLAIN.
Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways. This variation means that some individuals have traits better suited to the environment than others.
Give three differences between parenchyma and selerenchyma?
Answer:
Parenchyma cells have thin primary walls and usually remain alive after they become mature while Sclerenchyma cells have thick lignified secondary walls and often die when mature.
Parenchyma forms the "filler" tissue in the soft parts of plants while Sclerenchyma provides the main structural support to a plant.
Parenchyma cells are usually loosely packed with large intercellular space while Sclerenchyma cells has no intercellular spaces between the cells.
If a P-Wave took 5 minutes to reach a seismic
station and the earthquake began at 4:23:05, what
time did the P Wave reach the station?
Answer: 4:28:05
Explanation: if it takes 5 minutes to reach a station, just add 5 to the amount of minutes you already have (23) to get 28. And the hour and seconds stay the same.

although farmers once used only organic fertilizers to replenish nutrients in the soils, some have been replaced with synthetic fertilizers. Although synthetic fertilizers keep nutrient levels high and increase crop yields, they can have an effect on the environment. Which of the following would most likely lead to a ban of synthetic fertilizers?
A. Synthetic fertilizers help prevent the spread of diseases.
B. Synthetic fertilizers are less expensive than organic fertilizers.
C. Synthetic fertilizers increase the potential for environmental pollution.
D. Synthetic fertilizers provide nutrients, like nitrogen that can disrupt nutrient cycling.
Answer: C. Synthetic fertilizers increase the potential for environmental pollution.
Explanation:
A fertilizer is a material which when applied to soil ,supply one or more plant nutrients essential to the growth of plants.
Fertilizers could be organic ( obtained from nature ) or could be synthetic ( made artificially in labs).
Though synthetic fertilizers such as urea keep nutrient levels high and increase crop yields but they also kill beneficial microorganisms in the soil that convert dead human and plant remains into nutrient-rich organic matter. The non biodegardable synthetic fertilizers seep into groundwater and increase its toxicity, causing water pollution.
Synthetic fertilizers damage the natural makeup of the soil. Plants that grow in soils which use synthetic fertilizers are deficient in iron, zinc, carotene, vitamin C, copper and protein.

If the food on the island is small seeds, what finch is best adapted? Explain why
Answer:Adaptation in Darwins Finches. Beak depth, which is correlated with body size and the ability to crack larger seeds, varies according to drought conditions: plants produce fewer, harder seeds in dry years and more, softer seeds in wet years. Only larger birds with deeper depths survive in drought years.

Through which of the following
would a sound wave travel the fastest?
a. Water vapor in the air
b. Water in the glass
c. Surrounding air
d. The glass
Answer:
D. The glass.
Explanation:
Sound travels fastest through solids. This is because molecules in a solid medium are much closer together than those in a liquid or gas, allowing sound waves to travel more quickly through it.

what is the cause and effect of stop codone mutation?
Answer:
Nonsense mutations occur when a premature nonsense or stop codon is introduced in the DNA sequence. When the mutated sequence is translated into a protein, the resulting protein is incomplete and shorter than normal. Consequently, most nonsense mutations result in nonfunctional proteins.
Hope this helped! :)

A stone 'X' of mass 2 kg is at the height of 2 m from the ground level
Another similar stone 'Y' of mass 4 kg is at the height of 4 m from the ground
level. What is the difference between their potential energy?
un minutes Calculate
Answer:
120 joule.
Explanation:
Given
For the stone X
Mass (m) = 2 kg
Height (h) = 2 m
Acceleration due to gravity (g) = 10 m/s²
Then we have the formula to calculate the potential energy
P.E 1 = mgh
= 2 * 10*2
= 40 joule
Now for Stone Y
mass (m) = 4 kg
height (h) = 4 m
acceleration due to gravity (g) = 10 m/s²
Now
P. E2 = mgh
= 4 * 10* 4
= 160 joule
Now the difference between their potential energy is
= P. E2 - P. E 1
= 160-40
= 120 joule
Hope it will help you :)
The charged particles in the beams that Thomson studied came from atoms. As these particles moved away from their original atoms, they formed a visible beam. The current model of the atom includes protons, neutrons, and electrons.
What is the best use of an atomic model to explain the charge of the particles in Thomson’s beams?
An atom’s negative particles are surrounded by positive matter, so the positive particles are easier to remove.
An atom’s positive particles are surrounded by negative matter, so the negative particles are easier to remove.
An atom’s smaller negative particles are at a distance from the central positive particles, so the negative particles are easier to remove.
An atom’s larger positive particles are at a distance from the central negative particles, so the positive particles are easier to remove.
The question to the above information is;
What is the best use of an atomic model to explain the charge of the particles in Thomson's beams?
Answer;
An atom's smaller negative particles are at a distance from the central positive particles, so the negative particles are easier to remove.
Explanation;
-Atoms are comprised of a nucleus consisting of protons (red) and neutrons (blue). The number of orbiting electrons is the same as the number of protons and is termed the "atomic number" of the element.
J.J. Thomson discovered the electron. Atoms are neutral overall, therefore in Thomson’s ‘plum pudding model’:

Compare and contrast chromosomes and gene
Answer:
Genes are segments of deoxyribonuceleic acid (DNA) that contains the code for a specific protein that functions in one or more types of cells in the body. Chromosomes are structures within cells that contains a person’s genes. Genes are contained in chromosomes, which are in the cell nulecus.
Explanation:
Answer:
quick answer
Explanation:
Both genes and chromosomes are inherited from our parents. Genes are like the instruction manual that put us together. They determine our biological predisposition. Chromosomes are the structures that contain our genes, but unlike genes they also determine gender. Chromosomes are made up of two tightly-wound sister chromatids.

Edge 2021
According to the concept of "survival of the fittest," if a population of birds eats worms that they find deep under ground by using their beaks, birds that have longer beaks would be more likely to survive, which is present in Option B.
What is natural selection?Natural selection is a process in which the only organisms that can adapt to the environment and its changing conditions are chosen by nature, such as in the case of the Darwinian finches. when different types of birds are present in the ecosystem and all can get their favorable food source, but when an adverse climate occurs and food is only available in deep ground, only long-beaked birds can survive because they can get food. This explains the survival of the fittest by the natural selection.
Hence, as per “survival of the fittest," if a population of birds eats worms that they find deep under the ground by using their beaks, birds that have longer beaks would be more likely to survive, which is present in Option B.
