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.

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.

Therefore, More red photosynthesis pigments were produced to absorb green light.

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.

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.

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.

consumers, how much energy is transferred?

100 kcal
1,000 kcal
10 kcal
Plz help me which one is it!!!!!

Answers

Answer: 1,000kcal

10% of 10,000 is 1,000.

The amount of energy transferred if 10% is transferred to the primary  consumers is 1000kcal

Given the following parameters

Amount of kcal the producer have = 10,000kCal

Percentage transferred to the primary consumers = 10% of the amount produced

Get the amount of energy transferred;

[tex]Energy \ transferred = \frac{10}{100} \times 10,000\\ Energy \ transferred =0.1 \times 10,000\\Energy \ transferred =\frac{10,000}{10}\\Energy \ transferred =1000kcal[/tex]

Hence the amount of energy transferred if 10% is transferred to the primary consumers is 1000kcal.

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
invade the land and salt the fields. What were they hoping to accomplish by doing
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.
