what would happen is there was a change in the DNA ?

Answers

Answer: B) the protein would also change

DNA is a dynamic and adaptable molecule. As such, the nucleotide sequences found within it are subject to change as the result of a phenomenon called mutation. Depending on how a particular mutation modifies an organism's genetic makeup, it can prove harmless, helpful, or even hurtful. Sometimes, a mutation may even cause dramatic changes in the physiology of an affected organism. Of course, in order to better understand the varying effects of mutations, it is first necessary to understand what mutations are and how they occur.

The muscles of a tired jogger begin to undergo lactic acid fermentation. As a result, the jogger is most likely to
A) absorb more oxygen with each breath
B) release less carbon dioxide with each breath
C) experience an increase in blood pH
D) experience a “burning” sensation in the muscles

Answers

Answer:

D: experience a “burning” sensation in the muscles

Explanation: Based on the information in the lesson, this option makes the most sense.

"When lactate builds up, the blood’s pH drops and the muscles fatigue. This is why you may feel your muscles "burn" from the buildup of lactic acid."

In the given scenario, the jogger will experience a “burning” sensation in the muscles. The correct option is D.

What is muscle fatigue?

Muscle fatigue is the loss of a muscle's capacity to create force. It can be caused by strenuous exercise, but abnormal fatigue can also be caused by impediments to or interference with the various stages of muscle contraction.

When lactate levels rise, the pH of the blood falls and the muscles fatigue. That's why individuals may feel their muscles "burn" as lactic acid builds up.

Thus, the correct option is D.

Which of the following processes produces the most ATP? a aerobic respiration b glycolysis c alcoholic fermentation d lactic acid fermentation

Answers

Answer:

b) glycolysis

Explanation:

Up to 36 ATP can be produced from one glucose molecule through aerobic reactions. Therefore, option (A) is correct.

What is aerobic respiration?

Aerobic respiration supplies energy to fuel all cellular functions. The reactions result in the production of ATP, which can then be put to use to power other life-sustaining processes, such as growth, repair, and maintenance.

The release of energy that was stored in carbohydrates and lipids during photosynthesis and the subsequent availability of that energy to living organisms is the purpose of the series of enzyme-controlled events known as aerobic respiration.

Glycolysis, the Krebs cycle and respiratory electron transport contribute to the production of 36 ATP for every molecule of glucose that is used up during aerobic cell respiration.

After 5 days, the effects of the insecticide are collected. what is the independent variable and dependent variable

Answers

Answer:

Independent variable: amount of insecticide

Dependent variable: effects of insecticide on frogs

Explanation:

Dependent variable in a research experiment, is the variable that is being studied, tested and measured by the researcher, while the independent variable is the variable that causes the dependent variable to change, when it is varied.

In this case, the amount of insecticides that is varied in quantity, is the independent variable that the researcher manipulates, while the independent variable is the effects caused by these varied amount of insecticide on frogs, which is tested and measured.

Farmers brought nutria, a type of large rodents, from South America to North America in the 1990s. They wanted to raise the rodents for their fur. Some of these rodents escaped into the wild and became a major pest in the Gulf Coast and Chesapeake Bay regions. Grasses and shrubs in these regions are vital, because they provide food and shelter for many species. They also help in preventing soil erosion. The nutria are eating up all the grasses and shrubs, which affects the food cycles of these regions. The entire ecosystems are being disrupted.

Moreover, nutria pose a direct threat to humans. These rodents are an effective vector for carrying parasites that can cause disease in humans. They also damage property. The burrows created by nutria can damage dams and building foundations as well as cause erosion near streams and lakes.

Answer:

The apple snail is a native species of Argentina, Bolivia, Brazil, Paraguay, and Uruguay. Southeast Asia legally imported this alien species to use it as a protein source. Later, this species was brought to places like Hawaii as a source of food.

Like most, if not all, invasive species, the apple snail outcompetes native species for resources. This is because it reproduces rapidly (laying hundreds of eggs every few weeks) and lacks predators. As a result, the snails spread rapidly to aquatic biomes and modify the natural balance of aquatic ecosystems.

Two organisms mate and produce infertile offspring. Which is a true statement about why it is not able to reproduce?

A. The parents are a different genus and species

B. The parents are a different species, but the same genus

Answers

Answer:

a

Explanation:

a is the correct answer

The statement which is true about why it is not able to reproduce is that the parents are a different genus and species. Thus, the correct option for this question is A.

What is Species?

Species may be defined as the collection of organisms that can significantly reproduce with one another in nature and produce fertile offspring.

According to the context of this question, the process of speciation takes place when the members of similar populations no longer interbreed with one another in order to produce fertile offspring within their natural environment. So, the mating of two organisms can not produce fertile offspring until they belong to the same genus and species.

Therefore, the statement which is true about why it is not able to reproduce is that the parents are a different genus and species. Thus, the correct option for this question is A.
