es el intercambio de material genético entre dos cromátidas hermanas idénticas.
Primero se descubrió usando el método de tinción de Giemsa en una cromátida que pertenece al complejo de cromátidas hermanas antes de la anafase en la mitosis. La tinción reveló que se pasaron pocos segmentos a la cromátida hermana que no se tiñeron. La tinción de Giemsa pudo teñirse debido a la presencia de una base análoga de bromodeoxiuridina que se introdujo en la cromátida deseada.

_______ 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.
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.
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.

Fill in the boxes in the template to identify the nucleotide sequence from 3' to 5' of the tRNA anticodon that will recognize codon 5 and the tRNA anticodon
Complete question:
(C) Fill in the boxes in the template to identify the nucleotide sequence, from 3' to 5´ of the tRNA anticodon that will recognize codon 5 and the tRNA anticodon that will recognize codon 510 of the mRNA template and to identify the amino acids that will be added at these two positions.
In the attached files you will find the image
Answer:
Codon Anticodon Amino Acid
5 CGG → GCC → Arginine, Arg
510 UAG → AUC → Stop
Explanation:
Some theory that you need to know to answer the question:
Each tRNA has two important sites. One of them that couples with the codon of the mRNA molecule, named anticodon. The other site couples with an amino acid through the action of the aminoacyl-tRNA synthase enzyme. The whole complex, amino acid + enzyme + tRNA is named aminoacyl-tRNA. Considering that there are twenty amino acids available, there are also twenty complexes of aminoacyl-tRNA, one for each amino acid.
tRNA allows amino acids to align according to the nucleotidic sequence in the mRNA molecule.
Once the new peptidic link joins, placing together the new amino acid to the growing peptidic chain, the binding between the amino acid and the tRNA molecule breaks. The tRNA is now free to join another amino acid and repeat the cycle.
Now, to fill in the boxes, you need to pay attention to two things:
Anticodon: In this box, you need to place the sequence of bases that pairs with the mRNA codon. Amino Acid: In this box, you need to place the amino acid that is codified by the mRNA codon.For instance, let us say that the codon of mRNA is CUC.
The anticodon for this sequence is GAG (because guanine joins cytosine and adenine joins uracyl).
The amino acid placed on the 3´extreme of the tRNA molecule will be the one that is codified by the codon, NOT the anticodon. So, as the codon is CUC, the amino acid will be Leucine, Leu. Do not use the anticodon GAG to fill these boxes. Remember that tRNA is translating information carried by the mRNA, so we need to use this information to grow the protein.
So, in the problem, there are two codons: 5 and 510
Codon Anticodon Amino Acid
5 CGG → GCC → Arginine, Arg
510 UAG → AUC → Stop

Answer:
The central dogma of molecular biology describes the flow of genetic information in cells from DNA to messenger RNA (mRNA) to protein. It states that genes specify the sequence of mRNA molecules, which in turn specify the sequence of proteins.

If you assume that the high projection is correct, what is one way the larger
human population can ensure it has enough food?
The one way the larger human population can ensure it has enough food is by finding more efficient ways of growing crops. Therefore, the correct option is option B.
What is population?The term "population" is frequently used to describe the total number of people living in a particular location. To estimate the number of the residents within a certain territory, governments conduct censuses. The phrase has particular use in the domains of ecology and genetics and is also used to refer to plants, animals, and microbes.
An region with a sexual populace is one in which interbreeding between any two individuals therein is both conceivable and more likely than cross-breeding between individuals from other places. The one way the larger human population can ensure it has enough food is by finding more efficient ways of growing crops.
Therefore, the correct option is option B.

a) The following account was written by a confused student.
Rewrite the paragraphs with the mistakes corrected:
"Shortly after a heavy meal, glucose is absorbed from the large intestine, and its concentration in the blood cells goes up. This
rise is detected by the liver, which releases the hormone
insulin into the blood. Insulin makes the pancreas remove the extra glucose from the blood and store it as starch.
Later on, the concentration of glucose in the blood drops. The liver breaks down fat so that it goes up again.
(b) Explain why, some time after the meal, the blood glucose
concentration falls below its correct level.
Following a heavy meal, the small intestine absorbs glucose into the blood, and the rise is detected by the pancreas, which releases insulin. The liver absorbs glucose as a result of the action of this hormone, and the blood glucose level falls.
What is the role of insulin?Insulin aids the body in glucose regulation. The correct paragraph is as below. "Shortly after a heavy meal, glucose is absorbed from the small intestine, and its concentration in the blood cells goes up. This rise is detected by the pancreas, which releases the hormone insulin into the blood. Insulin makes the liver take the extra glucose from the blood and store it as glycogen. Later on, the concentration of glucose in the blood drops. The liver breaks down glycogen so that it goes up again. After a while, the majority of glucose from the meal is stored as glycogen in the liver, resulting in less free glucose in the blood as the level drops".
Hence, insulin regulates the blood glucose level by decresing the level and storing it in muscle and liver cell.
