Answer:
0.2Hz
Explanation:
The wavelength of a radiowave can be calculated this;
λ = v/f
Where;
λ = Wavelength (m)
v = speed (m/s)
f = frequency (Hz)
Based on the information provided in this question, λ = 1.5 x 10^9 meters, c = 3 × 10^8m/s, f = ?
Hence, using λ = v/f
f = v/λ
f = 3 × 10^8 ÷ 1.5 x 10^9
f = 2 × 10^(8-9)
f = 2 × 10^-1
f = 0.2Hz

What effect do glaciers have on plant life?
Glaciers bring quantities of minerals beneficial to plants as the water runs off melting ice.
Glaciers bring quantities of minerals that choke plant life as the water runs off melting ice.
Glaciers has no effect on plant life other than helping distribute necessary water.
Glacial flooding is destructive to plant life as silt builds in rivers.
Answer:
Glaciers bring quantities of minerals beneficial to plants as the water runs off melting ice.
Explanation:
Glaciers are natural reservoirs of water and minerals that may persist to dry conditions during the summer season. Ice melting provides water and minerals during the warm season, which is therefore critical for plants living in dry summer environments. Moreover, it is well-known that the 'melt-water' (i.e., water released by the melting of glacial ice) also affects downstream stream water temperatures, creating a microhabitat that may be beneficial to the life of plant species.
describe the main difference between a bright field, compound light microscope and a dissecting microscope
Answer:
Please find the main difference in details between these two microscopes below
Explanation:
Compound microscopes and dissecting microscopes are two types of light microscopes. This means that both types of microscope uses light as a source of view. However, they are used for different purposes despite this similarity.
- The compound microscope is used to view the internal features of a small specimen by looking through it. This is due to the high magnifying power of its objective lenses (40x - 1000x).
- On the other hand, dissecting microscopes are used only to view the surface of a large specimen owing to its low magnifying power. It can be used to view a three dimensional object.

By genetic modification and evolutionary processes, biodiversity is increased and decreased by habitat loss, population reduction and extinction. The number and relative abundance of species present in a given biological organization is simply species diversity (population, ecosystem, Earth).
Answer:
Genetic Modification is a procedure to change the qualities of a plant, creature or miniature life form by moving a bit of DNA from one living being to an alternate living being. This is done through focused expulsion of the ideal qualities from the DNA of one living being and adding them to the next living being. This strategy has for instance been utilized to create growths and microorganisms that produce drugs.
Evolution is the cycle by which current creatures have dropped from old progenitors. Evolution is liable for both the surprising similitude we see over all life and the astonishing variety of that life.
Explanation:
Evolution is change in the heritable qualities of organic populaces over progressive ages. These attributes are the statements of qualities that are given from parent to posterity during generation. Various attributes will in general exist inside some random populace because of transformation, hereditary recombination and different wellsprings of hereditary variety. Evolution happens when transformative cycles, for example, regular choice (counting sexual choice) and hereditary float follow up on this variety, bringing about specific qualities getting more normal or uncommon inside a populace.
It is this cycle of development that has offered ascend to biodiversity at each degree of natural association, including the degrees of species, singular life forms and atoms.

write any two method for identification of fossils?
Traces of the dead bodies present on the sedimentary rocks are fossils identification parts. By the physical appearance as well we can see the fossils and the types.
What are the ways by which fossils form ?Molds and the casts are the ways by through the fossils are formed out.
Something becomes fossil then it is mineralized or later becomes is made of the minerals. This is usually meaning an increase in the weight. A fossil bone is just heavier than the normal bone that is noticeably so. So if object is heavy then it just might be the fossil. Sediment might fill mould and later form cast fossil.
Have an eye that looks for the detail Look for the regular lines along with the marks or the patterns on the pebbles just like ridges or the growth lines in the shell. Looking for the tiny pieces that are among the beach pebbles and not only the big stones. Often the crinoid stems or the belemnites can also be small as the little fingernail.

5. It is winter and everyone in your family has the flu virus but you. Which 10 points
body systems work together to help prevent you from catching the flu?
The cardiovascular system transports the disease fighting cells around the body, the
respiratory system warms the air and weakens the flu virus.
The cardiovascular system transports the disease fighting cells around the body, the
immune system recognizes and kills the pathogen before it can make you sick.
The muscular system creates the disease fighting cells responsible for fighting off
diseases; the excretory system removes pathogens along with liquid waste before it
can make you sick.
The respiratory system warms the air and weakens the flu virus; the immune system
recognizes and kills the pathogen before it can make you sick
Answer:
immune system recognizes and kills the pathogen before it can make you sick
Explanation:
the respiratory and cardiovascular system mostly just spread the disease
the muscular and excretory system have no part in fighting the disease

Answer:the valves prevents the backward flow of blood
Explanation:
Answer:
The labelled structure of the heart is attached below. The valves in the heart prevent the backward flow of blood. These valves are actual flaps that are located on each end of the two ventricles (lower chambers of the heart). They act as one-way inlets of blood on one side of a ventricle and one-way outlets of blood on the other side of a ventricle.

problems?
a. Increased predation
b. Decreased amount of food
c. Disorientation
d. Disrupted breeding times
Answer:
Light pollution does not affect predation levels, so the correct answer is A
Explanation:
Increase predation is one of them which is not affected by Light pollution.
What is light pollution?Artificial illumination that is undesirable, improper, or excessive is referred to as light pollution.Light pollution, also known as artificial light at night, is the excessive or inefficient use of artificial outdoor light that disturbs wildlife's normal routines, adds to the buildup of carbon dioxide (CO2) in the atmosphere, interrupts human sleep, and obscures the night sky's stars.What is predation?One creature kills and eats another in predation. Predation offers energy to the creature that kills, the predator, in order to prolong its life and encourage reproduction at the expense of the organism that is eaten, the prey. Predation has an ecological impact on species on two levels.Hence, the correct option is A.

how could changing one mRNA codon change a protein?
Answer:
the outcome of a frame shift mutation is complete alteration of the amino acid sequence of a protein. This alteration occurs during translation because ribosomes read the mRNA strand in terms of condons,or groups of three nucleotides. theses groups are called the reading frame.
Explanation:
hope that helps.:)
Changing one mRNA codon will change a protein because each protein
have their specific mRNA codons.
The mRNA codon are translated into a single amino acid during polypeptide
formation. Changing one mRNA codon will result in the formation of a
different type of protein.
The mRNA codon comprises of three base pairs and a change in an amino
acid such as Alanine which has a codon of GCA which when replaced by
GAC will form aspartic acid.
