Explanation:
got it right on edg quiz (see pic)
hope this helps :)
All nutrients that enter the circulation are processed by the digestive and excretory systems simultaneously, with the exception of oxygen, which is taken in by the respiratory system. The correct answer is a) The digestive system fuels the cells and the excretory system rids the body of the cells’ waste.
What is the digestive and excretory system?Nutritive substances are absorbed by the digestive system, and any that are not are expelled. By continuously purging the blood, the excretory system works in tandem to remove metabolic waste products from cells throughout the body.
The digestive system takes in the nutrients and water from the diet. All across the body, the circulatory system delivers nutrition, water, and oxygen to cells. The respiratory system, the excretory system, and the skin all remove waste from the cells.
The excretory system filters the bloodstream for nutrients and gathers unneeded components in your urine for disposal, whereas the digestive system absorbs nutrients, collects them, and then eliminates the undigested solids (feces).
Therefore, the correct answer is a).

What is the DNA sequence that was used for synthesizing this mRNA sequence? A.TTTgctatactatagtac ...
Answers
Answer:
The generated mRNA sequence will be AAACGAUAUGAUAUCAUG...
Explanation:
DNA consists of nucleotides, which are composed of nitrogenous bases that are called Adenine (A), Thymine (T), Guanine (G) and Cytosine (C). These nitrogenous bases must pair with each other for the DNA molecule to be formed. In DNA, Adenine only pairs with Timine, while Guanine only pairs with Cytosine. In this case, we can say that the nitrogenous bases pair with other bases that are complementary to them.
The mRNA is formed from the DNA and the enzyme that produces the mRNA, uses the sequence of nitrogenous base pairs of DNA to produce the mRNA, however, the mRNA does not have the Thymine base, but the Uracil (U) base that pairs with Adenina. In this case, when the DNA contains the Adenine base, the mRNA produced will present the Uracil base. When the DNA has the Guanine base, the mRNA will have the cytosine base.
Thus, a DNA with the base sequence TTTgctatactatagtac will present an mRNA with the base sequence AAACGAUAUGAUAUCAUG ...

Which model of replication did the actual results of the Meselson-Stahl experiment support? Explain your answer.
Answers
Answer:
Semi-conservative replication
Explanation:
After the double-helix discovery of Watson and Crick, there were three possible models about the DNI replication:
The Conservative model stated that the two strands of DNI together were the template of another new molecule. The final product was the original double-stranded molecule and the new molecule. The semi-conservative model stated that the original DNI molecule separated into two strands, and each of them served as a template for the synthesis of a new complementary strand. The replication product would be two double-stranded DNA molecules, each carrying an original strand a new one. The Dispersive moles stated that the replication product would be two molecules made by a mixture of segments of the original and the new molecules.Meselson and Stahl joined to discover which of the models was the correct one. To do it they used E. coli and Nitrogen isotopes.
First, they extracted DNI from bacteria grown in a medium with N¹⁴ and got its density band by centrifugation. Then they grew bacteria in a medium with N¹⁵, extracted their DNI molecules, centrifugated them, and got the density band, which was heavier than the firsts ones. The researchers then transferred bacteria grown in medium with N¹⁵ to a medium with N¹⁴, and they allowed only one replication process to occur. DNI was extracted and centrifugated again, and a new band appeared. This band was an intermediate form between bands of DNI-N¹⁵ and DNI-N¹⁴.This event eliminated the conservative model. If this model were correct, the expected result would be to get two bands: one corresponding to the density DNI-N¹⁵ and the other corresponding to the density DNI-N¹⁴.
Bacteria grown in a medium with N¹⁵ and then transferred to a medium with N¹⁴ were finally allowed to replicate twice. Their DNI was extracted and centrifugated. The result was two bands: one of them coincided with the intermediate band, and the other one with the DNI-N¹⁴.This result was conclusive because if the dispersal model were correct, these two bands should not appear, as all the DNI strands would have part of the original molecule.
With this experiment, Meselson and Stahl proved that the correct replication model was the semi-conservative one.
In North American forest, two species of birds, nuthatches and brown creepers, forage on the same trees for insects. Brown creepers feed on insects near the bottom of the tree trunk, while nuthatches feed on insects in the top part of the tree. The difference in foraging behavior most likely affects the nuthatches and brown creepers by: allowing birds to avoid many types of predators allowing birds to avoid many types of predators reducing competition between the birds for resources reducing competition between the birds for resources preventing the birds from interbreeding with each other preventing the birds from interbreeding with each other establishing dominance between the birds for nesting sites
Answers
Answer:
The correct answer is - reducing competition between the birds for resources.
Explanation:
In this ecosystem, the two species of birds brown creepers and nuthatches share habitat in the same tree for their food resources are insects. Brown creepers feed on resources on the bottom of the tree whereas nuthatches feed on the top of the tree.
By this, they avoid competition between these two birds for the same food resources in the same tree. The competition would be more if both have depended on the insects all over the tree.

energy for cells?
A. hydrolysis
B. breaking the bond between the 2nd and 3rd phosphate
C. removing the ribose sugar
Answers
Answer:
B
Explanation:
when one phosphate group is removed by breaking a phosphoanhydride bond in a process called hydrolysis, energy is released.
The ATP molecule releases energy for cells by breaking the weak phosphate bond and converting it to ADP. This process is called A. hydrolysis.
What is the hydrolysis of ATP? Our body requires energy to perform various body activities and functions. This includes muscle contraction, digestion, transportation of molecules etc. This energy comes from the breakdown of ATP. The ATP molecule that is generated during the respiration process is broken down into ADP. This process is called the hydrolysis of ATP. The energy that is released during the breakdown of ATP is used to perform the required functions. Out of the three phosphate bonds, the weak phosphate bond is broken down to fulfil the energy needs of the body.Thus, whenever the cell requires energy, the ATP is broken down into ADP by the process of hydrolysis.

(examples include humans, cows, plants, etc.) for now, until we see the other answers, we will skip b. It can't be C, because on a trusted website, it states that the unified cell theory states that: all living things are composed of one or more cells; the cell is the basic unit of life; and new cells arise from existing cells. Rudolf Virchow later made important contributions to this theory. ... All organisms are made up of one or more cells.
If we take a look at D, It could be true because in another trusted website, it states that Oxygen helps organisms grow, reproduce, and turn food into energy. ... Although other animals may use different organs to breathe with, they all get oxygen into their bodies through respiration. So, Looking back up to B, it seems less likely now that we've viewed everything. D is the answer, I wasn't paying attention earlier, haha.

Gressel the Goblin is making an inventory of Darklord Ganondorf’s treasure horde following a raid by some violent fellow named link. The horde now contains only 2150 gems (as in $). Gressel notices that there were twice as many green-gems (worth 1) as blue-gems (worth 5) and 13 fewer blue gems than red-gems (worth 20). How many red, blue and green gems are there remaining in the horde?
Answers
➥ Let the number of blue gems be x, green gems be 2x and red gems be x + 13.
According to question,
5x + 1 × 2x + 20(x + 13) = 2150
On solving equation, we get
27x + 260 = 2150
27x = 2150 - 260
27x = 1890
x = 1890/27 = 70 blue gems.
2 × 70 = 140 green gems.
70 + 13 = 83 red gems.
Hence, We have 70 blue gems, 140 green gems and 83 red gems.
