One way that cells maintain homeostasis is by controlling the movement of substances across the cell membrane.

Answers

Answer:

True

Explanation:

One way that a cell maintains homeostasis is by controlling the movement of substances across the cell membrane. The lipid bilayer is selectively permeable to small, nonpolar substances. Proteins in the cell membrane include cell-surface markers, receptor proteins, enzymes, and transport proteins.

Which of the following is Bernoulli's principle?
1. As the speed of a moving fluid increases the pressure within the fluid decreases.
2. As the speed of a moving fluid decreases the pressure within the fluid increases.
3. As the speed of a moving fluid increases the pressure within the fluid increases.
4. As the speed of a moving fluid decreases the pressure within the fluid decreases.

Answers

Answer:

1. As the speed of a moving fluid increases the pressure within the fluid decreases.

Explanation:

Hope this helps!

The Bernoulli's principle is applied when the speed of a moving fluid increases as the pressure within the fluid decreases. Thus, the correct option is 1.

What is Bernoulli's Principle?

The inverse relationship between pressure and speed at a point in any fluid is called Bernoulli's principle. Bernoulli's principle states that "At points along a horizontal streamline, higher pressure regions have lower fluid speed and lower pressure regions have higher fluid speed".

Bernoulli's principle is based on the law of conservation of energy. The total energy (pressure energy, potential energy and kinetic energy) of a flowing liquid under constant pressure at different points differ.

Therefore, the correct option is 1. With the increase in speed, the pressure within the fluid decreases.

In an investigation to determine a factor that affects the growth of rats, a student exposed 100 rats of the same age and species to identical conditions, except for the amount of living space and the amount of food each rat received. Each day the student measured and recorded the weight of each rat. State one major error that the student made in performing this

Answers

Answer:

Violating 'Ceteris Paribus' {Other factors constant} assumption, as both food & space are varied (simultaneously)

Explanation:

Weight Growth is the dependent (effected) variable in this case. And, independent (causal) variables are food amount are living space respectively.

However particular independent factor's (food or living space) impact on dependent variable ie weight growth : can be determined only by - examining individual variable (food or living space) impact on weight growth. So, either of the two variables should be varied, & not both should be varied simultaneously.

This would imply depiction of each factor's clearer individual impact on the dependent factor.

The protein, lipid, and carbohydrate compositions of the cytoplasmic and extracellular sides of membranes are different from one another. Why is this the case? (3 points)



a) Some membrane components are synthesized outside of the cell, while others are synthesized in the cytosol.


b) The two sides of a cell membrane face different environments and carry out different functions.


c) The molecular composition of the inner and outer layers of the cell membrane is determined by genes.


d) Proteins only function on the cytoplasmic side of the cell membrane, which results in asymmetry across the membrane.

Answers

Answer:

The protein, lipid, and carbohydrate compositions of the cytoplasmic and extracellular sides of membranes are different from one another , this happens because the two sides of a cell membrane face different environments and carry out different functions.

Explanation:

PROTEINS , LIPID AND CARBOHYDRATES , all are the components of the plasma membrane , located at different sites .

PROTEINS -: The main component of plasma membranes is proteins. Two key categories of membrane proteins are available: integral and peripheral. As their name implies, integral membrane proteins are incorporated into the membrane: they have at least one hydrophobic region that anchors them to the phospholipid bilayer's hydrophobic center. Others just stick partway through the membrane, while others extend from one side of the membrane to the other and on either side are exposed.

On the outside and inside surfaces of membranes, peripheral membrane proteins are found which are bound either to integral proteins or to phospholipids. Peripheral membrane proteins do not stick into the hydrophobic center of the membrane as opposed to integral membrane proteins, and appear to be more loosely bound.

LIPID -: Phospholipids, arranged in a bilayer, make up the plasma membrane 's essential cloth. Since they are amphipathic, they are well-suited for this function, meaning they have both hydrophilic and hydrophobic regions.

The hydrophilic or "water-loving" component of a phospholipid is its head, which includes a phosphate group that is negatively charged, as well as an additional small group that can also be charged or polar.

Its long, nonpolar fatty acid tails make up the hydrophobic, or "water-fearing," portion of a phospholipid. The tails of fatty acids can interact easily with other non-polar molecules, but interact poorly with water.

CARBOHYDRATES -: The main component of plasma membranes is carbohydrates. In general, they are located on the outer surface of the cells and are either bound to proteins (glycoproteins forming) or to lipids (glycolipids forming). These chains of carbohydrates can consist of 2-60 units of monosaccharide and can either be straight or branched.

Hence , the correct option is B.

What are the five categories of adaptations?

Answers

Migration, hibernation, dormancy, camouflage, estivation ( aestivation)

The five categories of adaptations are migration, hibernation, dormancy, camouflage, astivation.

What is migration?

The term migration has been defined as when the birds, animals, or human beings leaves the native place and move towards a new place due to weather or other physical condition is known as migration. Generally, when it is too much cold the birds of that particular area migrated to the place where they found suitable temperature for their survival.

The stage of dormancy is the stage when seed gets closed and not able to germinate as it closes its outer wall. The term hibernation is defined as the particular time period in which the organism hybernate himself for a period of time when the weather or the outer environment is not safe, or fit for his survival.Generally, when it is too much cold the birds of that particular area migrated to the place where they found suitable temperature for their survival.

Answers

Answer:

disaccharides

Explanation:

they are formed by linking 2 monosaccharides through condensation

monosaccharides are simple sugars or glucose

Disaccharides are those types of carbohydrates that, when hydrolyzed by acids or enzymes, produce two molecules of monosaccharides that may or may not be identical. Thus, option A is correct.

What is important in formation of disaccharides?

Mono- and disaccharides, sometimes known as sugars, make up a significant portion of the carbohydrates included in food.

Disaccharides function similarly to other carbohydrates as a source of energy for the body.

When we consume foods containing disaccharides, our systems convert them into monosaccharides, or simple sugars, for absorption in the small intestine.

This condensation process is also referred to as a dehydration reaction, since a water molecule is released during this process.

Therefore, disaccharide is formed from monomeric subunits.

What is the elephant getting when the bond is broken in sucrose?

Answers

Answer:

The elephant is getting Energy.

Explanation:

The elephant is getting Energy because sucrose is been hydrolysed and the bonds are broken down by enzyme sucrase isomaltase present in the intestine. Inches the bonds are broken, it is broken into glucose and fructose which is absorbed by the small intestine into the blood. The glucose serve as energy source or it is been stored as fly oven in the liver which is later broken down to glucose which is use for metabolic pathways to produce energy.

The elephant gets OXYGEN when the bond is broken in sucrose.

Sucrose is a disaccharide consisting of one glucose unit and one fructose unit, both units are linked by a glycosidic bond.

The hydrolysis of sucrose generates a 1:1 mixture of glucose and fructose.

The glycosidic bond can be exemplified by the central atom of oxygen that connects both monosaccharides in the sucrose molecule.

Sucrase is an enzyme that binds to sucrose and catalyzes its hydrolysis to produce glucose and fructose.

In conclusion, the elephant gets OXYGEN when the bond is broken in sucrose.
