In your letter, you need to explain how the theory of evolution is supported by evidence. Be sure to include the 4 pieces of evidence for evolution as well as an example of each.

Answers

Answer 1

The evidence of evolution was posited by Charles Darwin. The theory of evolution states that all species are related and that they change over time

The different postulates of Drawin support the natural selection phenomenon. Darwin stated that the organisms that are fit and are able to change according to evolution are able to survive. This was known as the survival of the fittest.  

The evidence of the  evolution can be studied by fossil record , comparative embryology , molecular biology , and comparative anatomy.

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.

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.

asap!!! A researcher illuminated a filament of cyanobacteria with light that passed through a prism, thus exposing different segments of cyanobacteria to different wavelengths of light. He found that the bacteria in the green light changed in color from green to red after multiple weeks of exposure but were still reproducing at the same rate. What can you conclude about the change in pigmentation of the cyanobacteria exposed to green light?

1.) More chlorophyll a was produced in response to the green light exposure

2.) The cyanobacteria were dying and were changing color in response

3.) Red light instead of green light was being absorbed by the chloroplasts

4.) More red photosynthesis pigments were produced to absorb green light

Answers

Answer:

#4.. More red photosynthesis pigments were produced to absorb green light

Chlorophyll, carotenoids, and phycobiliproteins, as well as additional classes like scytonemin, which are more focused on cyanobacterial cells' protection, are the three main classes of photosynthetic pigments that stand out in cyanobacteria. Thus, option D is correct.

What are the characteristics of cyanobacteria?

Many plants depend on cyanobacteria for their wellbeing and development.

Being able to transform inert atmospheric nitrogen into an organic form, like nitrate or ammonia, makes them one of the very few types of organisms that can do so.

Cyanobacteria are microscopic, photosynthetic organisms that are classified as bacteria.

They were once known as blue-green algae. Since dense growths frequently color water green, blue-green, or brownish-green, they were previously referred to as blue-green algae.

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.

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.

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.

A tactic used long ago by conquering nations on those they sought to control was to

this?

Answers

Answer:

I don't know this answer sorry dear

Explanation:

hope other wilp help you soon

The invading nations aimed to devastate the agricultural productivity and food supply of the local population.

Salting the fields was a deliberate act of agricultural sabotage with long-lasting consequences. The process involved spreading large amounts of salt over the farmland, which effectively rendered the soil infertile, inhibiting the growth of crops and making it nearly impossible to cultivate food. This strategy was particularly effective in ancient times when agriculture was the primary means of subsistence.

The devastation caused by salting the fields not only impacted the present generation but also affected future generations as the soil remained barren and required significant efforts to be reclaimed for agricultural use. This tactic was not only meant to suppress immediate resistance but also to instill fear and discourage other potential adversaries from rebelling against the invading nation.
