Too much water in spaces surrounding cells is known as _________.a. osmosis
b. ions
c. edema
d. cations

Answers

Answer 1
Answer: The answer is c. edema.

Edema is a condition in which there is too much water in spaces surrounding cells. It results when blood vessels are leaky, so a fluid from blood vessels enters the nearby tissue. This extra fluid accumulates and, thus, tissue swells.

Ion is an atom or a molecule with a net charge, either positive (cation) or negative (anion). Osmosis is the movement of solvent molecules from a higher solute concentration to a lower solute concentration.

Answers

Activating the muscles involved in smiling may actually make us feel happier and this is an example of Facial feedback effect . The facial feedback effect states that skeletal muscle feedback from facial expressions can influence emotional experience. Facial movement plays a causal role in regulating emotional experience and behavior.

Final answer:

The idea that creating a physical smile can cause feelings of happiness is an example of the facial feedback hypothesis. This suggests that our facial expressions can impact our emotions, a concept backed by various studies. This is observed in universal expressions like laughter that signal joy or pleasure.

Explanation:

The statement that activating the muscles involved in smiling can make us feel happier is an example of the facial feedback hypothesis. This hypothesis suggests that facial expressions can influence our emotions. For example, physically forcing yourself to smile can potentially lead to a lighter mood. This concept has been examined in studies like the one by Soussignan in 2002, which found that a Duchenne smile, a genuine smile that involves the muscles around both the mouth and eyes, can trigger positive emotions and physiological responses. Similarly, laughter is a universal expression of joy or pleasure recognized across cultures. Strategies like these can be a part of successful happiness interventions, as seen in the study by Seligman et al., 2005 where participants recorded good things from their day and saw increases in happiness.

What are two ways bacteria provide nutrients to humans?

Answers

Answer:

By producing vitamins or breaking down molecules.

Explanation:

  • Producing vitamins that humans cannot produce by themselves. Lactobacillus, Bifidobacterium, and members of the gut microbiota are examples of probiotics that synthesize vitamin K and others like biotin, pantothenic acid, riboflavin, and thiamine.
  • Another way is by breaking down with enzymes molecules that cannot be digested by humans, for example, fiber, starches, and sugars.

I hope you find this information useful and interesting! Good luck!

in certain species of roses, white roses and red roses are incompletely dominant to each other. when a red rose and a white rose are crossed, a pink rose is produced. what is the probability of producing a white rose when a red rose is crossed with a pink rose

Answers

The answer is 0%.

If white and red roses are incompletely dominant, the phenotypes are as following:
AA - red roses
AB - pink roses
BB - white roses

So, a cross between a red (AA) and a pink rose (AB) will result in only red or pink roses:
Parents:            AA     x      AB
Offspring:      AA    AA    AB     AB

Answer:

o%

Explanation:

If white and red roses are incompletely dominant, the phenotypes are as following:

AA - red roses

AB - pink roses

BB - white roses

So, a cross between a red (AA) and a pink rose (AB) will result in only red or pink roses:

Parents:            AA     x      AB

Offspring:      AA    AA    AB     AB
