What portion of a pre-mRNA molecule may be cut to be discarded?

ans:- In eukaryote cells the primary transcript (pre-mRNA) is processed. One or more sequences (introns) are cut out.

Since one of the offspring has white fur both of Sam's rabbits have a genotype of Gw. G standing for the dominate trait of grey fur while w stands for the recessive trait of white fur. When you put this information in a genotype chart you will get these possible genotypes for their offspring: GG, Gw, Gw, and ww. This means that there is a 75% chance that the offspring will have grey fur while there is a 25% chance they will have white fur. So this is how we know that Sam's rabbits most likely have genotypes of Gw.

Plants, algae, bacteria and even some animals photosynthesize.

Explanation:

A process essential to life, photosynthesis uses carbon dioxide, water and sunlight, and converts it into sugar, water and oxygen.

Answer:

Cold temperatures cause many plants to become dormant.

Explanation:

This is asking for the effect, not cause. Cold temperatures make many plants die or dormant. Due to the cold, plants can't live or survive due to frozen water and minimal sunlight due to snow. Plants usually freeze through and die, but the plants that survive are eaten my herbivores/omnivores. This causes the competition for food. Fewer plants leads to fewer herbivores. Fewer herbivores lead to fewer carnivores and omnivores.

The competition for food among animals in temperate forests increases in the winter months because cold temperatures cause many plants to go dormant, which is present in the second option.

The temperature has an effect on the plants, such as the plants' height, and the plant density that is seen in the equatorial region is different from the plant density that is seen in the near polar regions. A plant can do photosynthesis and survive in a normal temperature, whereas in a harsh temperature, many adaptations are seen in the plants, and in an extreme cold climate, a plant becomes dormant as the enzymatic function of the cell is affected and hence competition for the food is seen among the animals.

Hence, the  competition for food among animals in temperate forests increases in the winter months because cold temperatures cause many plants to go dormant, which is present in the second option.

An ames test, bacteria that start producing histidines are called revertants is True.

In an Ames test, bacteria that start producing histidines are indeed called revertants. Revertants are mutant bacteria that regain the ability to synthesize histidine due to a reversion of the original mutation. This is a key principle of the Ames test, a widely used bacterial mutagenicity assay that detects potential mutagens by measuring their ability to induce mutations in the histidine biosynthesis pathway of bacteria.

By observing the appearance of revertants, which are able to grow in histidine-deficient media, researchers can assess the mutagenic potential of a test substance. The number of revertant colonies formed is compared to a negative control to determine the mutagenicity of the substance being tested.

Explanation:

Calcium is released and sequestered differently in skeletal and cardiac muscles, this difference is due to the specific properties of the muscle fibers of each muscle.

In skeletal muscle, calcium is released from the sarcoplasmic reticulum (SR) into the cytoplasm in response to an action potential. In cardiac muscle, calcium is released from the SR and also from the extracellular space. This difference in calcium handling is physiologically relevant because in cardiac muscle, calcium ions play a key role in the contraction and relaxation of cardiac muscle fibers. Calcium ions bind to the protein troponin, which then triggers a series of events that result in muscle contraction. The cardiac muscle fibers are able to release calcium ions from the SR and extracellular space, this allows for a more rapid and sustained contraction of the cardiac muscle, which is necessary for the efficient pumping of the blood throughout the body.

Suppose albino corn has been discovered to have in its leaves a chemical that is important to stopping the growth of cancer cells. The farmers could alter the expected 3:1 green to albino ratio and produce more albino plants for cancer research use selective breeding techniques

To produce more albino plants for cancer research, farmers could use selective breeding techniques. First, they would need to identify the albino plants with the highest concentration of the cancer-fighting chemical in their leaves. Then, these plants would be crossbred with other albino plants that also have high levels of the chemical. This would increase the chances of producing offspring with the desired trait.

Farmers could also use genetic engineering techniques to insert the gene responsible for producing the cancer-fighting chemical into other plants, such as green corn, to create new varieties that have the desired trait. By using these methods, the farmers could alter the expected 3:1 green to albino ratio and produce more albino plants for cancer research.

b. Luetta Moore Park playground: Nonexcludable. No free rider problem.

c. National defense: Nonexcludable and nonrivalrous. Free rider problem exists.

d. Subway train: Nonexcludable. Free rider problem possible during peak hours.

a. The Great Smoky Mountains National Park: It is nonexcludable because it is difficult to prevent individuals from accessing the park. However, it is rivalrous as the park's resources, such as campsites or parking spaces, can be depleted. Both nonexcludability and rivalry suggest that the park is both nonexcludable and rivalrous. The free rider problem may occur since people can enjoy the benefits of the park without paying for its maintenance or preservation.

b. Playground at Luetta Moore Park: The playground is nonexcludable since it is difficult to prevent people from using it. However, it is nonrival as one person's use does not diminish the usability of the playground for others. Therefore, it is only nonexcludable. The free rider problem may not apply here since the use of the playground does not impose costs on others.

c. National defense: National defense is both nonexcludable and nonrival. It is nonexcludable because it is challenging to exclude individuals from benefiting from defense. It is nonrival because the defense provided to one person does not diminish the defense available to others. Both characteristics make national defense both nonexcludable and nonrival. The free rider problem is prevalent in national defense since individuals can benefit from defense without incurring the costs associated with it.

d. Subway train: A subway train is nonexcludable since it is difficult to prevent individuals from using it. However, it can be rivalrous during peak hours when overcrowding may limit the available space. Therefore, a subway train is only nonexcludable. The free rider problem may not be significant here as long as there are no capacity constraints or overcrowding issues.

Lizards are able to lose their tails and regrow them by a process called epimorphic regeneration. The type of cellular process taking place in epimorphic regeneration involves a complex cellular process such as the formation of a blastema with undifferentiated progenitor cells

When a lizard loses its tail, cells near the wound site rapidly activate and form a structure called a blastema. This blastema consists of undifferentiated cells known as progenitor cells, which have the ability to differentiate into various cell types. During epimorphic regeneration, these progenitor cells divide and differentiate to replace the lost tail structures, such as muscles, bones, nerves, and blood vessels.

The process is regulated by various molecular signals and growth factors, which guide the formation and organization of the new tissues. This ensures that the regenerated tail closely resembles the original one in both form and function. In summary, epimorphic regeneration in lizards involves the formation of a blastema with undifferentiated progenitor cells, which then divide and differentiate to regrow the lost tail structures under the guidance of molecular signals and growth factors.
