asambeis [7]

Answer:

C. Water will move into the cell through osmosis. The salt and water concentrations will become similar inside and outside the cell.

Explanation:

Osmosis is the movement of water from its higher concentration to the lower concentration through a semi permeable membrane. Here, the cell have higher salt concentration and lower water concentration as compared to its outside. Since cell membrane is semi permeable, salt cannot pass through it. So, water will move into the cell through osmosis to equalize the salt and water concentration on either side of cell membrane.

When heart muscles cells are deprived of oxygen, the heart still pumps. what must the heart cells be able to do? transform lacta
katrin2010 [14]
The heart cells must be able to continue aerobic metabolism when skeletal muscle cannot. Aerobic metabolism is a part of cellular respiration and involves body cells making energy through glycolysis, the citric acid cycle, and the electron transport/oxidative. It is done in the heart at a rate below 85% of maximum heart rate and does not use vigorous muscle contraction. fatty acids , ketone bodies and carbohydrates are the primary substrates of the heart metabolized to generate ATP. The metabolic demands of the heart are the largest than any other organ in the body, and normal cardiac metabolism is required to fuel contractile function and viability.

Answer:

A scientist's response to the increase in food poisoning sick patients should be examining the type and source within the foods consumed.

Explanation:

Food poisoning involves the effects that decomposed or contaminated food can have on a group of people who eat it, and can cause illness in all or most individuals.

Although patients' symptoms should be treated and preventive education provided, the best course of action for a scientist is to investigate the cause.

The response of a scientist to the increase in food poisoning cases is to determine the type and source of food, as well as the nature of the alteration it has -decomposition, contamination, bacteria- in order to <u>eliminate the source and avoid new cases</u>.

  • <em>The other options may be valid in the face of the appearance of food poisoning cases, but they are not the best procedure with which a scientist would respond. </em>

Whatts the mechanism behind emotions? why do we have emotions?
Alexeev081 [22]
In biopsychology, there is a system in the brain which is called the limbic system. The limbic system is responsible for one's memory, emotions and instincts -drives.
Many researchers suggest that the existence of emotions helped the animal kingdom to respond to sociality and survive better, emotion can also be translated into care and love. These traits also aid why infants, babies and other offsprings of animals are cared for which has a great influence on the survival of the species.

Amygdala, responsible for pain, aggression and grief which is anterior to the hippocampus factors why our memories have incorporated and is strengthened with emotions at that specific circumstance.
