Mitochondria have highly folded inner membrane that increase the membranes surface area for atp production. What concept does this illustrate?
1) a cell ability to maintain homeostasis is critical for life
2) catalysts speed up chemIcal reactions in cells
3) all livIng things are composed of cells
4) a cells structure is related to its function
Mitochondria have a highly folded inner membrane that increases the surface area for ATP production. This explains that a cell's structure is related to its function. So the correct answer is option 4.
What is the role of mitochondria in a cell?In an eukaryotic cell, the mitochondria are present and produce ATP through the Krebs cycle, the electron transport chain, and other cellular processes. The inner membrane of mitochondria is folded, and this membrane consists of many complexes that are required for the electron transport chain.
Due to the transfer of electrons, a proton gradient is formed that allows the formation of ATP. More complexes (ATP synthase) can fit into the membrane as it folds, and ATP production increases. To produce more energy, the mitochondria are made this way. Apart from this, other organs such as the intestine have villi that are highly folded to increase the rate of absorption.
Hence, the shape of each cell is related to its function. Option 4 is true for the statement.

Characteristics of asthma include:___________.a. Chronic inflammatory disorderb. Airway hyperresponsivenessc. Alveolar collapsed. Genetic susceptibilitye. Airway remodeling
Answer:
The correct answer is a.
Explanation:
Asthma is characterized by a chronic inflammatory process of the airways in which a variety of cells predominate, such as eosinophils, neutrophils, and mast cells. Chronic inflammation produces an increase in airway reactivity and recurrent episodes of wheezing, respiratory distress, intercostal pulling, coughing, and chest tightness, especially at night and in the morning. Asthma is a disease in which there is bronchial hyperresponsiveness, which is an exaggerated response of the bronchial mucosa and leads to bronchospasm and bronchitis.
Gastrin secretion in response to elevated ph within the stomach is an example of:__________.
Answer:
It is an example of enzyme activation through the pH of the environment surrounding the enzyme.
This phenomenon is called proenzyme, proenzymes are inactive enzymes that, due to chemical changes in the environment that vary, are activated or not depending on these.
Explanation:
Proenzymes, generally the best known or named, are found in the digestive system, where the sequential digestion of food is essential, with an order, and the enzymes must be controlled or activated at certain moments of digestion.
Proenzymes can be activated by the presence of chemicals, pH acids and even pH alkalinity, the change of the medium is what gives the enzyme permission to start with its reaction effect.
Usually this happens with enzymes that must be controlled, and that their activity must be in certain periods so as not to generate pathologies or even destroy a tissue of the organism.

"Genetic power is far more potent than atomic power. And it will be in everyone's hands. It will be in kits for backyard gardeners. Experiments for schoolchildren. Cheap labs for terrorists and dictators. And that will force everyone to ask the same question—What should I do with my power?— which is the very question—science cannot answer."
Answer:
These facts are true and disturbing
Explanation:
Genetics is a discipline that has advanced incredibly in the last years. For example, by using the versatile CRISPR-Cas9 genome editing system, we are now able to insert literally any sequence into a given genome in vivo. The CRISPR-Cas9 is a technology that can be used in a regular molecular biology laboratory. It is expected this technique will enable in the near future to correct genetic disorders that have plagued mankind since times immemorial. However, genomic technologies like that could be used by malignant persons to hurt innocent people, thereby it is imperative that countries regulate their use.

( WILL MARK BRAINLIEST ) Please help ASAP
A. The cell membrane has many functions, but its primary action is to regulate the movement of materials into and out of the cell
B. The cell membrane has numerous functions, but its primary role is to keep organelles contained within the cell
C. The cell membrane has many functions, but its primary action is to act as a barrier to keep foreign substances from moving into the cell
D. The cell membrane's primary function is to move waste out of the cell
The correct answer as to which best describes the function of a cell membrane would be that the cell membrane has many functions, but its primary action is to regulate the movement of materials into and out of the cell. The correct option would be A.
The cell membrane primarily delimits the cell and act as an interface between the inner content of the cell and its surrounding.
The cell membrane is selectively permeable. Thus, it regulates the movement of materials between the cell's matrix and the surrounding.
Other functions of the cell membrane include:
By regulating the movement of materials in and out of the cell, the cell membrane ensures that the optimal range of concentration of substances is maintained within the cell. In other words, it maintains homeostasis.By surrounding the cell, the plasma membrane becomes the first line of contact for anything that might want to harm the cell. Hence, it serves protective functions.By selectively allowing and influencing some materials to move out or inside the cell, the cell membrane plays an integral role in the transportation of materials.

A food change is an ecosystem flows from green algae, to freshwater snails, to small fish, and finally to large fish. Which organism is the primary consumer?
Large Fish
Small Fish
Green Algae
Freshwater Snails
Answer:
The correct answer is - freshwater snails.
Explanation:
Producers are organisms that produce their own food and not depends on any other organism by the process of photosynthesis such as algae. Primary organisms on the other hand directly depend on the producers for their food and often gt killed by secondary consumers.
Freshwater snails are the perfect example of the primary consumer as they get their food and energy from algae and are the primary source of food and energy for small fishes.
