Answer:
They use advance technologies in agriculture.
Explanation:
There is a direct relationship between thriving civilization and it’s agriculture system because they use advance methods and technologies in agriculture instead of traditional practices. They use heavy machinery for tillage in order to save the time, use high yielding varieties, use proper dose of fertilizers, use of pesticides and weedicides in order to protect the crop. They harvest the crop by using thresher in order to avoid post harvest losses. In short, they use all technologies available to make a higher yield in order to earn more profit.

" The role of oxygen in the regulation of respiratory rhythm is quite significant"
Answer:
Pneumotaxic centre in the pons region of the brain can moderate functions of the respiratory rhythm centre. Neural signals from this centre can reduce the duration of inspiration and thereby alter the respiratory rate. A chemosensltive area is situated adjacent to the rhythm centre to make necessary adjustments in the respiratory process. Receptors associated with aortic arch and carotid artery also can recognise changes in CO
2
and H+ concentration and send necessary signals to the rhythm centre for remedial actions. The role of oxygen in the regulation of respiratory rhythm is quite insignificant.
So, the correct answer is 'Both Assertion and Reason are correct and Reason is the correct explanation for Assertion'.
Explanation:
Answer:
this means that the oxygen is maintained by the respiratory rhythm.

Determine whether the statement is true or false, and why. "Learned behavior is present from birth, requires no thought, and is
essential to survival."
A. False, it should read, "Instinctive behavior is present from birth, is developed through observation and experience, and allows animals to adapt to
changes in the environment."
False, it should read, "Instinctive behavior is not inherited, requires no thought, and is developed through experience and observation."
C. True
False, it should read, "Learned behavior is not inherited. It is developed through observation and experience and allows animals to adapt to
changes in the environment."
Answer: It is, (False, it should read, “Learned behavior is not inherited. It is developed through observation and experience and allows animals to adapt to changes in the environment.”)
Explanation:
The statement is false, it should read, "Learned behavior is not inherited. It is developed through observation and experience and allows animals to adapt to changes in the environment."
What is learned behavior?Learned behaviors are those behaviors or characteristics that we learn from observing other people, learning and reading, and our experiences. It is the best type of characteristic of humans because learning just by observation is very efficient.
This behavior can not be inherited by another person because it is not in our genes. The behavior can be acquired by nature and the learning ability of a human, not inheritance. The genetic qualities are only inherited.
Thus, the correct option is D, false.

Explanation:
Describe at least 2 benefits and 2 drawbacks there might be for animal cells (including humans) to make their own food through photosynthesis.
Answer:
here.
Explanation:
Benefits would be that we'd be autotrophs, meaning that we'd be independent of an external source of organic compounds for energy. All we'd need is the sun and carbon dioxide. It's a simpler and less energy-consuming process than having to undergo digestion, absorption and then assimilation.
Cons would include the fact that it provides a very limited amount of energy only for the day. Which means humans will be inactive at the night time because the energy won't be able to support our activities. Since we don't have a surface area as big as leaves, our deep cells (like those of our organs and bones) will suffer most from the lack of energy since sunlight cannot penetrate our fat, muscles and bones. This can cause organ failure if our cells solely depended on diffusion.
Our high metabolic rate and our need for energy makes photosynthesis very very ineffective.

n your lab you are studying the genome of venomous rattlesnakes to find the gene which codes for their venom glands. You have two rattlesnakes, one rattlesnake has a mutation but can still produce venom. You compare his DNA to a normal rattlesnake. What type of mutation has occurred? Normal: AATCGCTACGCACGTCAG Mutated: TATCGCTACGCACGTCAG
Answer:
There are no options but the kind of mutation that occurred by carefully observing both sequences is:
POINT SUBSTITUTION MUTATION
Explanation:
Mutation is any change, whether small or big, in the nucleotide sequence of a gene (DNA). Mutation occurs from time to time in an organism either by a mistake during DNA replication or induced by a mutagen (mutation-causing substance). Mutation can be of different types depending on the effect on the mutant.
In this case of comparing the DNA sequence two rattle snakes, the sequences of the two snakes are:
Normal: AATCGCTACGCACGTCAG
Mutated: TATCGCTACGCACGTCAG
By carefully observing the two DNA sequences, one would realize that the only difference in the two sequences is the first nucleotide base. That is, in the normal sequence, th first base is Adenine (A) while in the mutated sequence, the first base is Thymine (T).
This type of mutation that involves only one nucleotide base is called POINT MUTATION. It can also be noticed that base "A" was changed "T". Hence, this is a type of SUBSTITUTION MUTATION because a single base was replaced by another in the sequence.

The essence of meiosis is that a. specialized cell division reduces the chromosome number by half b. gametes are formed that are diploid c. specialized cell division doubles the chromosome number d. gametes are formed that are haploid e. a and d are correct
Answer:
e. a and d are correct
Explanation:
Meiosis produces 4 daughter cells that are haploid. Haploid means they have half of the chromosomes of the parent cell.
The essence of meiosis is that specialized cell division reduces the chromosome number by half and gametes are formed that are haploid.
Therefore option e is the right answer.
What is meiosis?A single cell splits twice during the meiotic process, resulting in four cells with half the original genetic material. These cells are our sex cells—eggs in females and sperm in males—and they are produced by a specific form of germ cell division in sexually reproducing species. Two rounds of division are necessary, and the end product is four cells with just one copy of each chromosome. The goal is to produce gametes, or sperm and eggs, that contain half of the parent cells' genetic makeup. Meiosis is characterized by DNA replication, two rounds of cell division, and the production of four daughter cells, each of which has half as many chromosomes as the parent cell.To learn more about meiosis, refer

1. How are wavelength, frequency, and energy related to each other?
Answer:
wavelength: the distance between successive crests of a wave
frequency: the rate per second of a vibration constituting a wave, either in a material (as in sound waves), or in an electromagnetic field (as in radio waves and light)
electromagnetic energy is used for wifi, cell phones, microwave ovens etc.
the electromagnetic spectrum includes radio waves, microwaves, infrared radiation, visisble light, ultraviolet, xrays and gamma rays
the only part we can see is visible light
visible light can be characterised by the colours of the rainbow
the longest wavelength is red and the shortest is violet
when combined, the colour is perceived as white or beige
Answer:
Just as wavelength and frequency are related to light, they are also related to energy. The shorter the wavelengths and higher the frequency corresponds with greater energy. So the longer the wavelengths and lower the frequency results in lower energy.
Explanation:
WAVELENGTH=

FREQUENCY=
Frequency, in physics, the number of waves that pass a fixed point in unit time; also, the number of cycles or vibrations undergone during one unit of time by a body in periodic motion.
ENERGY=
energy, in physics, the capacity for doing work. It may exist in potential, kinetic, thermal, electrical, chemical, nuclear, or other various forms. There are, moreover, heat and work—i.e., energy in the process of transfer from one body to another.

41 Explain why you needed to use a water plant for this experiment
I suspect you are referring to a specific experiment, which measures the rate of photosynthesis at differing intensities of light. This experiment could certainly be done with land plants, but using a water plant makes it easier to have a simple way to measure the rate of photosynthesis--the counting of bubbles which come off a specific area of the plant. A water plant such as elodea (the type you commonly see in aquariums) does the process of photosynthesis just as plants that grow in the air do, but you can actually see the bubbles that indicate photosynthesis is occurring--they form on the leaves before they float to the surface, enabling an easy measurement of bubbles per minute.
Plants have chloroplasts, which in addition to giving plants their green color, perform photosynthesis, the process on which life on earth is dependent. They use the energy of the sun to use carbon dioxide and water to produce sugars and oxygen. When you are counting the bubbles on the underwater leaf, you are counting bubbles of oxygen formed during photosynthesis.
If a cusp is lost during preparation, which matrix band would provide the best support while restoring
Answer:
I would use a specialized or preformed matrix for the posterior sector.
Explanation:
Losing a cusp is a much more critical situation, that is, there will be less tooth remnant and less resistance to functional and parafunctional forces.
The matrices that are usually used in the posterior sector are matrices that must be burnished and already come with a format to better restore the functional unit of the occlusal surface.
It is important to clarify that cusps are only in the posterior sector and not in the anterior sector.
The cusps, even if they have the most correct selection of the matrix, will fail in their restoration if they are not performed according to the patient's occlusion, under a good dental integration system such as adhesion through resins, and respecting the normal antomy of the piece to be restored.

The CT reveals several issues with the cranial structure, one of which might be in the cribriform plate but the image isn't well defined. What non-invasive test can you do to test if the cribriform plate is severely damaged? Why?
The non-invasive test that can be used to test if the cribriform plate is severely damaged is called the pledget study.
CRIBRIFORM PLATE is the part of the ethmoid bone that forms the nasal cavity.
The olfactory nerve which is part of the cranial nerves passes through the small opening found in the cribriform plate.
A damage to the cribriform plate leads to cerebrospinal fluid (CSF) leak which usually comes out from the nose and ears.
Therefore to test if the cribriform plate is severely damaged, the pledget study is performed.
Pledget study is a non-invasive method of diagnosing a CSF leak.
To perform this test,
Cotton pads called Pledgets are placed in the nostrils.If the leaking fluid contains CSF it will be detected.The presence of CSF shows that there is damage to the cribriform plate.
This method is non invasive because it doesn't require the breaking or opening of any part of the body.
