The above-given statement that 'No exceptions to the central dogma exist. RNA is always transcribed from DNA, and RNA is translated to produce proteins' is false.
The above statement is false because of the process of reverse transcription.
In the field of biology, central dogma can be defined as a process through which mRNA is formed by DNA, under a process named transcription. The mRNA formed then forms proteins under the process referred to as translation.
However, in some organisms, like the retroviruses, the process of reverse transcription was discovered. Reverse transcription is the process by which RNA is converted into DNA which is an exception to the central dogma process. The process of reverse transcription is now being used in genetic engineering due to its various benefits.

Solution that has a higher solute concentration on one side of a membrane than the other side.
A solution that has a higher solute concentration on one side of a membrane than the other side is termed as a hypertonic solution.
The cell membrane is a semi-permeable membrane that allows selective entry of materials into and out of a cell. Due to this, a concentration gradient develops inside and outside of the cell.
Such a solution that has more solutes present is referred to as a hypertonic solution. As a result of the hypertonic solution, a concentration gradient will be developed. Of a hypertonic solution is present inside the cell, then water from outside will enter the cell. On the other hand, if a hypertonic solution is present outside the cell, then water from inside the cell will move outwards.
Although a part of your question is missing, you might be referring to this question:

what adaptations have allowed tetrapods to survive on land
Answer:
It is extremely useful for terrestrial organisms because it allows them to use their hindlimbs efficiently for locomotion on land. Since the aquatic ancestors of fishes and tetrapods had no such connection, one might guess that this feature first evolved serving the function of enabling terrestrial locomotion.
Answer: When the land animals began to use the fins for standing and walking, the girdle bones had to become stronger to support the body on the legs. These bones eventually became the femur (upper leg bone) and humerus (upper arm bone) of the tetrapods

Answer:
Aftershocks are sometimes just as hazardous as the main quake itself. In fact, aftershocks may be so strong that they're stronger than the main quake. ... While foreshocks occur around the same time of the main quake, aftershocks may not occur until days or weeks later! The point at the Earth's surface directly above the focus is called the epicenter of the earthquake. At the epicenter, the strongest shaking occurs during an earthquake.

Ecology, conservation and management of vernal pool ecosystems – proceedings from 1996 is a research paper
What is this research paper about?California has 32 million residents, and that number is still increasing remarkably quickly. Ninety-five percent of the state's wetlands have been lost due to rapid population increase (Dahl, 1990). Vernal pools are one type of wetland that has seen exceptionally severe losses. This study addresses the urgent need to justify the creation of an ecologically sound compensation scheme for vernal pools that will be part of a larger vernal pool conservation strategy. They also talk about how to maintain and restore the functional integrity of vernal pool wetland ecosystems by creating a compensating mitigation plan that is ecologically based. They think vernal pool conservation can be carried out while also improving effectiveness within the current federal, state, and municipal regulatory framework.

The diagram below shows a phospholipid molecule.
Which of the following best describes how this molecule is produced by eukaryotic cells?
Question 12 options:
The nucleus sends out mRNA to the smooth ER (endoplasmic reticulum) so it can assemble the phospholipids using amino acids that are transported into the cell by the cell membrane. Vacuoles carry glucose to the smooth ER to supply the energy.
The enzymes needed to assemble it are from the Golgi. The smooth ER (endoplasmic reticulum) assembles the phospholipids using fatty acid tails that are transported into the cell through the cell membrane. Energy for the reaction comes from the mitochondria as ATP.
The enzymes needed to assemble it are from ribosomes. The rough ER (endoplasmic reticulum) assembles the phospholipids using energy from the mitochondria. The cell membrane transports new amino acids into the cell that are changed in the phospholipid.
The nucleus sends instructions out to the smooth ER (endoplasmic reticulum) to build the phospholipid. The cell membrane transports fatty acid tails into the cell to be used, and energy for the reaction comes from the mitochondria as ATP.

When an archaeologist finds an ancient artifact on a dig, how should they determine its relative age?.
There are several ways for an archaeologist to determine the relative age of an ancient artifact on a dig.
The first one is relative dating. In this process, the archaeologist has to assume that the sites lower layers are assumed to be older than those that lie above them because of stratification. Assumptions can be wrong that is why it is not widely accepted.
The second one is carbon dating. It is one the most accurate and widely use dating techniques. The archaeologists use the amount radioactive carbon decay to determine the artifact's date.

If a DNA strand has 32 % guanine before semi conservative replication occurs, what
percent thymine will each new strand have after replication?
Answer:I believe that the answer would be 18
Explanation:
32 divided by 2 is 18
If a DNA strand has 32% Guanine before semi-conservative replication occurs, then the percent Thymine will each new strand have after replication will be 18%.
The deoxyribonucleic acid (DNA) is a double helix molecule composed of four types of nucleotides: Adenine (A), Thymine (T), Cytosine (C) and Guanine (G).In DNA, Adenine (A) always pairs with Thymine (T), whereas Cytosine (C) always pairs with Guanine (G). The replication of DNA is semi-conservative because after replication each DNA molecule contains one original DNA strand and one newly-synthesized DNA strand.If a DNA molecule contains 32% of Guanine, then the content of G + C is equal to 64%, so the content of T + A is equal to 36% (64 + 36 = 100) and T content is 18% (18 + 18 = 36).In conclusion, if a DNA strand has 32% of Guanine before replication, then the percent of Thymine after replication will be 18%.

If the pride is taken over by new individuals, what happens to the females? males? cubs?.
The cubs are a significant barrier to reproduction when a new male coalition first takes control of a pride. Mothers of surviving cubs won't mate again until their young are at least 18 months old, but if their cubs are lost, they will mate right away.
Following that, males leave on their own or are driven out by other men who take control of their pride. It is common for a new male to kill all the cubs when he joins the pride in order to pass his genes on to all future cubs. The major function of males in the pride is defending the pride's territory.Female lionesses will devour the cubs of other pride, but not the cubs of their own pride. The "egalitarianism" of female lions stands in stark contrast to the autocratic behavior of wolves, wild dogs, and several other species, where dominant females prevent subordinates from reproducing.When a female lion gives birth, she leaves the pride and doesn't come back until the cubs are several weeks old. After that, the adult females band together to take care of and protect the young.Learn more about pride here:
