Answer:
The correct answer is - it would because both DNA and RNA have 3' OH.
Explanation:
Ammino acid will connect to the tRNA due to the fact that the process of aminoacylation of tRNA when DNA nucleotide is used will perform or act same the mechanism of Class II aminoacyl tRNA synthetase as both DNA and tRNA have 3'OH. This will get the help of 3'OH in the CCA to bond with charged amino acid.
Thus, the correct answer would be - it would because both DNA and RNA have 3' OH.

A researcher dried a feedstuff and determined that it contained 10 percent moisture. he took 1 gram (dry) of it and combusted it in the bomb calorimeter. the calorimeter contains 1 kg of water. The temperature was raised 2.7 degrees centigrade. Two kilograms (2000 grams) of dry matter of the material was fed to a pig each day for several days. the fecal collections of the pig averaged 200 grams dried per day for the last few days. the feedstuff analyzed 2.41 percent nitrogen (dry basis); the feces (dry basis) analyzed 4.6 percent nitrogen. (hint: the feedstuff contained _____ grams protein, the feces contained _____ grams protein.)
Answer:
Explanation:
The objective of the information given is to calculate the apparent digestible dry matter present in the feedstuff(%) and the apparent digestibility of the protein?
From the given information:
The apparent digestible dry matter present is:
[tex]=\dfrac{ (\text{Dry matter fed to the pig} - \text{Fecal matter of the pig} )}{\text{Dry matter fed to the pig}} \times 100 \%[/tex]
where;
Dry matter fed to the pig = 2kg = 2000 g
Fecal matter of the pig = 200
∴
The apparent digestible dry matter present = [tex]\dfrac{2000-200}{2000}\times 100\%[/tex]
[tex]=\dfrac{1800}{2000}\times 100\%[/tex]
= 90
Amount of Nitrogen(i.e. the protein) content present in the feedstuff = 2.41%
i.e.
2.41 g/100 g OR 48.2 g/2000 g feed
Amount of protein present in feces = 4.6% (4.6 g/100 g OR 9.2g/200g of feed)
∴
apparent digestibility of the protein is:[tex]=\dfrac{\text{Amount in feed }- \text{Amount in feces}}{\text{Amount in feed }}\times 100[/tex]
[tex]= \dfrac{(48.2 - 9.2)}{48.2}\times 100[/tex]
[tex]= \dfrac{39}{48.2}\times 100[/tex]
= 81%

What is transcription?In genomics, transcription is the method of generating an RNA copy of a gene's DNA sequence. This copy, known as messenger RNA (mRNA), transports the protein information encoded in the gene's DNA.
This RNA copy, known as messenger RNA (mRNA), contains the genetic information required for a cell to produce proteins.
It transports information from the cell's nucleus to the cytoplasm, where proteins are produced.
The entire gene is copied into a pre-mRNA, which includes exons and introns, during transcription. Introns are removed and exons are joined to form a contiguous coding sequence during the RNA splicing process.
Thus, as the introns are getting removed completely, the mRNA sequence for the given DNA sequence will be: AUG GCA UAU UUU UUA AUU GAA UCU GCA CGA GAA AAU GAA GCA ACU UAG.

1. Compare a positive feedback loop and negative feedback loop for homeostasis. Body temperature is an example of a negative feedback loop. Imagine that body temperature was regulated as a positive feedback loop and explain what would happen.
2. Look at the figure of the brain lobes in your textbook. Do you think the chimpanzee would have the same brain lobes as that of a human? How might the chimp brain differ from a humans? Keep in mind the chimpanzee is the humans’ closest relative.
Answer:
Homeostasis typically involves negative feedback loops that counteract changes of various properties from their target values, known as set points. In contrast to negative feedback loops, positive feedback loops amplify their initiating stimuli, in other words, they move the system away from its starting state.
Explanation:
Chimpanzee lobes may be smaller than human lobes

5 intestine: smooth
6 veins: smooth
7 biceps: striated
8 trapezius: striated
9 stomach: smooth
10 gastrocnemius: striated
Explanation:
Striated muscle is a type of tissue composed of repeated functional units called sarcomeres, which are the basic contractile unit of the muscle fiber. The striated appearance is caused by repeating bands of actin and myosin proteins. Striated muscle tissue is subdivided into two major parts: 1-cardiac muscle and 2-skeletal muscle. Skeletal muscle is a highly dynamic tissue that is mostly attached by tendons to the bones in the skeleton. This voluntary tissue (skeletal muscle tissue) is composed of multiple fascicles or bundles of muscle fibers. Moreover, cardiac muscle tissue, also known as myocardium, is a type of striated muscle that contracts and releases involuntarily, composed of cells called myocytes present in the heart. Finally, smooth muscle is a type of involuntary and non-striated muscle tissue localized within the walls of organs/structures (i.e., intestine, esophagus, stomach, uterus, urethra, bladder, blood vessels, etc.).

In the population of plant K, each plant has only red flowers or only white flowers. A farmer collected the seeds from plant K with red flowers to grow new plants. Explain why the new plants will have only red flowers
Answer:
nose
Explanation:
nosenosenosenosenosenosenosenosenosenosenose
The new plants will have only red flowers because the trait for red flowers is determined by a dominant gene, and all the plants in population K have the same homozygous genotype for the flower color.
In genetics, the flower color trait in population K is determined by genes present in the plants' DNA. There are two alleles, or gene variants, for the flower color: one for red flowers (let's call it R) and one for white flowers (let's call it r). The gene for red flowers (R) is dominant, meaning that even if only one copy of the gene is present in an individual's genotype (heterozygous), it will produce the red flower phenotype. On the other hand, the gene for white flowers (r) is recessive, which means it will only produce the white flower phenotype if two copies are present in the genotype (homozygous recessive).
In population K, all the plants have only red flowers, indicating that they must have the genotype RR. Since all the plants are homozygous for the dominant red flower gene (RR), when they reproduce, they can only pass on the dominant allele R to their offspring. As a result, all the new plants that grow from the seeds collected from these plants will also have the genotype RR and, therefore, express the red flower phenotype.
Since there are no plants in population K with the genotype rr (homozygous recessive), which is necessary for white flowers, there is no chance of white-flowered plants appearing in the new generation. Thus, the new plants will have only red flowers due to the uniformity of the homozygous dominant genotype in the original population.

If you are pushing on a box with
5N, and the box pushes back 5N,
what would the net force be?.
ΑΟ
A. ON
B. 25N
C. 10N
The correct answer is A. 0N, as there is no net force acting on the box.
The net force in this scenario can be determined by calculating the difference between the applied force and the opposing force. In this case, if you are pushing on a box with a force of 5N, and the box pushes back with an equal force of 5N, the net force would be zero.
Net force is the vector sum of all the forces acting on an object. In this situation, the applied force of 5N is countered by the opposing force of 5N exerted by the box. Since the forces are equal in magnitude and opposite in direction, they cancel each other out.
When the net force is zero, it means that the forces are balanced, resulting in no acceleration or movement of the object. The box would remain at rest or continue moving at a constant velocity if it was already in motion.
Therefore, the correct answer is A. 0N, as there is no net force acting on the box.
