The Peppered moth is white with black spots, which helps it blend in with the bark on beech trees. The burning of coal in Great Britain caused many beech trees to become black with soot. Over time, the Peppered moth became all black in order to blend in with the new bark color. What type of example is this? homeostasis metabolism organization adaptation

Answers

Answer:

adaptation

Explanation:

Adaptation in Biology refers to the process whereby an organism adjust to its natural environment in order to increase its chance of survival or in other words, the organism becomes better suited to its natural habitat by possession of some adaptive features.

In this example, a white peppered moth with black spots initially possess these color combination in order to blend to its natural environment, which is the bark on beech trees. However, due to the burning of coal in Great Britain which caused many of the beech trees to be black, the peppered moths had to ADAPT to this change in environmental color by becoming all black in order to blend in with the new bark color.

Therefore, this is an example of ADAPTATION.

Midwives caused childbed fever.

If doctors disinfect hands before delivering babies, then there will be less childbed fever.

o If a woman goes into the hospital then she will die of childbed lever.

Answers

The investigation for death of women in maternity ward is identified by scientific method of hypothesis testing.

H0 : Doctors caused child bed fever.

Ha : Midwives caused child bed fever.

Child bed fever is the infection in some part of female reproductive organs usually ovary which causes the abortion of a child or premature child birth.

The hypothesis to check Dr.Ignaz have to make a null hypothesis statement against which there will be alternative hypothesis statement which will cause the observation and then reaching a conclusion.

why is the linner wall of alimantary canal not digisteg although the digestive enzymes can digest all the materials that make cell?

Answers

Answer:

There are no options to this question but it can be answered by giving a general explanation. The answer is:

Because the digestive enzymes are not in direct contact with the cells that make up the walls of the alimentary canal. The walls are protected by mucuous lining.

Explanation:

Digestion of our ingested food is an important process for the effective functioning of our body system. Digestion is the process whereby food, which are usually macromolecules, are broken down into simpler molecules usable by the body. After food is taken in from the mouth (ingestion), it must be broken down by chemical and mechanical means.

The chemicals means is through digestive enzymes, which are proteinous chemical substances. The digestive system consists of the alimentary canal or digestive tract, which is a tube-like organ that forms the path for food passage. Since digestive enzymes secreted during digestion can disintegrate every macro biomolecule e.g protein, carbohydrate etc, it can also break down the molecules that make up the cells of the tract wall.

However, the digestive enzymes does not break down the cells of the canal's wall because the body system secretes mucus, which lubricates the passage of food along the canal. It also prevents the digestive enzymes from coming in contact and acting on the macromolecules that make up the cells of the walls of the alimentary canal.

The lac operon in Escherichia coli Group of answer choices promotes the expression of lactose-utilizing enzymes when lactose is absent from the environment. prevents lactose-utilizing enzymes from being expressed when lactose is absent from the environment. prevents lactose intolerance. prevents lactose-utilizing enzymes from being expressed when lactose is present in the environment.

Answers

Answer:

The correct answer is - prevents lactose-utilizing enzymes from being expressed when lactose is absent from the environment.

Explanation:

The lac operon or the lactose operon is a operon that is essential for the many bacteria like Escherichia coli for metabolism and transport of the lactose.

In the presence of the lactose in the environment of the cell the lac genes are expressed due to the isomer of of lactose called allolactose binds to the Lac repressor protein and do not allow to bind it to lac operator. But in the absence of the lactose, the lactose utilizing enzymes are not expressed  due to repressor bind to the lac operator and prevents the binding of RNA polymerase to the promoter.

A mutation occurred in the following DNA sequence AGCCTAGCC and the mutated form is now AGCCTTAGCC. Which of the following correctly describes the result of this mutation?

1.A deletion occurred so all of the amino acids added after the mutation may be wrong.

2.An insertion occurred so all of the amino acids added after the mutation may be wrong.

3.A substitution occurred so all of the amino acids added after the mutation will definitely be wrong.

4.An insertion occurred so all of the amino acids added after the mutation definitely will be different.

Answers

Answer:

Explanation:

1.A deletion mutation occurs when a wrinkle forms on the DNA template strand and subsequently causes a nucleotide to be omitted from the replicated strand.

2.This type of variant results in a shortened protein that may function improperly, be nonfunctional, or get broken down. An insertion changes the DNA sequence by adding one or more nucleotides to the gene.

3. A substitution mutation can cause the following: Change in the coding of amino acids codon to a particular stop codon resulting in an incomplete protein, which is usually non-functional. Can cause Silent mutations where a codon change can encode the same amino acid resulting in no changes in the protein synthesized.

4. when a premature nonsense or stop codon is introduced in the DNA sequence. When the mutated sequence is translated into a protein, the resulting protein is incomplete and shorter than normal. Consequently, most nonsense mutations result in nonfunctional proteins.

Describe and explain how temperature and light intensity affect the rate of photosynthesis?

Answers

Answer:

The rate of photosynthesis varies with light intensity and temperature.

Explanation:

The rate of photosynthesis varies with light intensity.it decreases as light intensity decreases and increase s as light intensity increases. However at much higher light intensity rate of photosynthesis becomes constant.

The rate of photosynthesis decreases with decrease in temperature.It increases as temperature is increased over a limit. But if light intensity is low increase of temperature has little influence on rate of photosynthesis.

(a)The strength of natural fibers is very less as compared to synthetic fibers.  Natural fibers are heavy in weight.  Natural fibers can be damaged by moths and other insects.  These fibers are not wrinkle-free.  These fibers are not long lasting and hence not durable.

(b)  Cellulose is termed as polymer because it is made up of many monomer units.

(c) Rayon is first man- made fibre it is known as artificial silk because it have properties that are similar to silk.

(d) Rayon possesses many properties of natural fibers since it is a semi-synthetic fiber. Nylon is a synthetic fiber and has properties that are completely different from natural fibers. The key difference between rayon and nylon is their resistance to wrinkles and tears.

(e) Nylon has since become a popular choice, as it has excellent wind resistance, good elasticity, mildew resistance, and is comparatively cheaper. The material is also lightweight and dries quickly.

(f) When the piece of cotton is burnt then it burns completely and produces no odour or smell. When nylon is burnt, It completely burns and produces burning paper like odour. When nylon is burnt then the nylon is completely shrink and starts to melt first and then produces odour during the time of burning

What effect does insulin have on the body? It raises blood-sugar levels. It lowers blood-sugar levels. It raises glucagon levels. It lowers glucagon levels.

Answers

it regulates blood sugar level.

Explanation:

Insulin helps control blood glucose ( sugar) levels by signaling the liver and muscle and fat cells to take in glucose ( sugar) from the blood. Insulin therefore helps cells to take in glucose (sugar) to be used for energy. If the body has sufficient energy, insulin signals the liver to take up glucose ( sugar) and store it as glycogen.
