4. A wave traveling at 200 m/sec has a wavelength of 2 meters. What is the
frequency of this wave?
Given that,
The speed of a wave, v = 200 m/s
Wavelength, [tex]\lambda=2\ m[/tex]
We need to find the frequency of this wave. The relation between wavelength, frequency and the speed is given by :
[tex]v=f\lambda\\\\f=\dfrac{v}{\lambda}\\\\f=\dfrac{200\ m/s}{2\ m}\\\\f=100\ Hz[/tex]
So, the frequency of this wave is 100 Hz.

The purpose of DNA replication is to * make changes in base pairs in order for an organism to evolve make an exact copy of a DNA strand for bacterial reproduction to repeat patterns of DNA in order to expand the bacterial genome to transribe information to RNA in order to synthesize proteins
Answer:
make an exact copy of a DNA strand for bacterial reproduction
Explanation:
The purpose of DNA replication would be to make an exact copy of a DNA strand for bacterial reproduction.
DNA replication is a process during which an extra copy of an organism's DNA is made following a series of steps. The replication usually precedes reproduction or the formation of daughter cells. Each daughter cells resulting from reproduction must have a complete genome that mirrors that of the parent or otherwise depending on the type of reproduction.
Without reproduction, DNA replication would not have been necessary.

Describe what might happen in the water cycle if
the amount of solar energy entering the Earth
system decreased.
When the amount of solar energy that enters the system become decreased, what may happen in the water cycle are:
evaporation will reduceclouds won't formprecipitation would dropfreezing will occurThe water cycle can be described as a biogeochemical cycle that depicts how water is being circulated and recycled within, above, and on the earth's surface.
A typical diagram showing a water cycle is attached below.
From the water cycle diagram, we can observe that a vital aspect of the water cycle involves the sun which supplies solar energy that heats up earth.
The solar energy entering earth makes it possible for evaporation of water as vapor which form clouds that leads to rainfall.
The solar energy is also important in melting of ice, thereby converting it to water to goes into oceans for evaporation.
The implication of having an earth system where the amount of solar energy that enters it is reduced is that:
evaporation of water will reduced, clouds will not be able to form, and we won't have enough rainfall, andice would be predominant as low solar energy that is required to melt the ice is reduced.In conclusion, when the amount of solar energy that enters the system become decreased, what may happen in the water cycle are:
evaporation will reduceclouds won't formprecipitation would dropfreezing will occurLearn more here:

_______ inputs to the system come from weathering of rocks, from windblown dust, and from precipitation, which can carry material great distances.
Answer:
Nutrient
Explanation:
Ecology can be defined as the scientific study of the relationship between living organisms such as plants and animals in relation to their physical and biological environment.
Nutrient inputs to the system come from weathering of rocks, from windblown dust, and from precipitation, which can carry material great distances. Various amount of nutrients are transported or transfered from terrestrial ecosystems through erosion and then deposited in aquatic ecosystems such as oceans, seas, and associated lowlands.
Erosion can be defined as a geological process which typically involves the wearing out of earthen (soil) materials and the transportation of these materials by natural forces like water, wind, etc. Soil erosion is greatest when the soil is steep.
Weathering can be defined as the physical and chemical breakdown of rock into smaller pieces called sediment. Weathering can be classified into two categories namely;
I. Physical weathering : it is the process of breaking rocks into pieces without affecting its chemical composition e.g temperature, abrasion and frost action.
II. Chemical weathering : it is the process of breaking rocks into pieces by chemical action which leads to changes in its chemical composition e.g carbonation, hydration, plant acid and oxidation.

How is lactase an example of fitness in humans?
[tex] \\ [/tex]
Evolutionary advantages. Lactase persistence is a text-book example of natural selection in humans: it has been reported to present stronger selection pressure than any other known human gene. However, the specific reasons as to why lactase persistence confers a selective advantage "remain open to speculation".
WHAT THEY DO IN HUMAN BODY?Lactase breaks down the lactose in food so your body can absorb it. People who are lactose intolerant have unpleasant symptoms after eating or drinking milk or milk products. These symptoms include bloating, diarrhea, and gas. Lactose intolerance is not the same thing as having a food allergy to milk.
In pastoralist populations, individuals with the lactase-persistence mutations were more likely to survive, reproduce, and pass on their alleles than people without the mutations, especially in times of famine.

The sedimentary rock layers are being weathered and eroded at different rates because the rock layers:
Explanation:
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. The particles that form a sedimentary rock are called sediment, and may be composed of geological detritus (minerals) or biological detritus (organic matter). The geological detritus originated from weathering and erosion of existing rocks, or from the solidification of molten lava blobs erupted by volcanoes. The geological detritus is transported to the place of deposition by water, wind, ice or mass movement, which are called agents of denudation. Biological detritus was formed by bodies and parts (mainly shells) of dead aquatic organisms, as well as their fecal mass, suspended in water and slowly piling up on the floor of water bodies (marine snow). Sedimentation may also occur as dissolved minerals precipitate from water solution.
