Growers often wrap potted plants in plastic sleeves prior to shipping. If plants remain in these sleeves too long, their leaves curl and fall off. Imagine you are working at a garden center and have been asked to make a presentation to a local garden club. Unit 5 DQ Question: Explain the processes that may cause the leaves to drop and fall.
Answer:
Shock, age and climate.
Explanation:
The processes that may cause the leaves to drop and fall are shock, age and climate. The plants drop their leaves due to shock when they experience by transplanting from place to another. When the leaves get older having yellow colour so due to no function it falls. The climatic condition is also responsible for the dropping of leaves. Those plants which can't grow in cool season so when the winter comes they shed their leaves and wait for the summer season.
For this task, you will imagine that you are a reporter for a scientific magazine. Your task is to explain the process of protein synthesis to someone who does NOT have a science background. Therefore, the explanation needs to be in simple enough terms for anyone to understand. You will organize your article in the following way: Structure and Function of DNA and RNA Transcription and RNA processing Translation Protein modification (general) You must also include the following terms: Double helix Helicase Codon Polymerase 5’ cap Poly (A) tail Introns Exons Splicesomes rRNA, tRNA, Mrna Ribosomes Anticodons E site, P site, A site Initiation Elongation Termination
Answer:
Please find the explanation below
Explanation:
Our nucleus is made up of a genetic material called deoxyribonucleic acid (DNA), which is a double-helical structure that stores the genetic information needed for the optimal functioning of any organism. DNA, alongside RNA are nucleic acids that are composed of NUCLEOTIDES subunits. The nucleotide consists of a pentose sugar (deoxyribose in DNA and ribose in RNA), nitrogenous base and a phosphate group.
However, the genetic information stored in the DNA molecule needs to be expressed in order to form useful products (proteins). This genetic expression is done in two stages viz: transcription and translation. Transcription, which is catalyzed by an enzyme called RNA polymerase is the process whereby the information stored in the DNA is used to synthesize a mRNA molecule. However, this mRNA molecule is considered pre-mature until it is processed. RNA processing occurs in three stages viz: 5' capping, polyadenylation, and splicing.
5' capping involves adding a 5' cap to the marks molecule. Polyadenylation involves adding a poly(A) tail to the mRNA molecule while splicing is the removal of introns (non coding regions) with the aid of Spliceosomes and joining of the exons (coding region). After processing, the mRNA becomes matured and ready to be translated.
Translation is the process whereby the mRNA transcript is used to synthesize a protein molecule. It occurs in the ribosomes (organelles for protein synthesis, a complex of rRNA and proteins) where the mRNA is read in a group of three nucleotides called CODON. The reading is done by the Anticodon of a transfer RNA (tRNA), which is complementary to the codon.
Translation occurs in three stages: initiation, elongation and termination. The mRNA attaches to the P site of the ribosomes (initiation) where it is attached to by a tRNA's anticodon complementary to it. The anticodon carries the amino acid corresponding the codon and shifts to the A-site. The addition of amino acid to the polypeptide chain continues (elongation) until a stop codon is encountered, which signals the end of the translation process i.e. termination. This causes the polypeptide (protein) to be released from the E-site.
The synthesized protein undergoes packaging and modification in the Golgi apparatus.
The first place that the reabsorption of water is not automatically coupled to the reabsorption of filtered solutes occurs in the PCT.
a. True
b. False
Answer:
False
Explanation:
The correct answer is false because Reabsorption of water and other filtered solutes like vitamins, sodium e.t.c. take place in the proximal convoluted tubules.
Reabsorption is when water and solutes in the PCT are removed and moved back into the blood and it's a process that take place through bulk transport.
The solutes and water are transported from the PCT to the interstitium and then move into peri-tubular capillaries and reabsorption in PCT is isosmotic i.e solutes have the same osmotic pressure.
which of the following MOST directly influences a measurable outcome in an experiment?
Answer:
Hello. You did not enter the answer options, but the factor that most directly influences a measurable result in an experiment is the manipulation of the variables.
Explanation:
In an experiment, the manipulation of variables becomes highly important so that it is possible to measure, that is, evaluate the result. This is because it is the variables that express values that represent the characteristics that are being analyzed and studied within the experiment. Therefore, the manipulation between them must be done in a very rational and balanced way so as not to modify the values shown by them, changing the data and generating false or immeasurable data.
On April 26, 1986, Reactor 4 at the Chernobyl Nuclear Power Station in Ukraine exploded, releasing radioactive isotopes into the air. The majority of the isotopes that were released and spreading thousands of miles were of the element iodine. As a class, discuss what endocrine glands would be most affected and how it would become apparent in the nearby population.
Answer:
In the given case, the thyroid gland will be affected the most due to the exposure of the element iodine. For the synthesis of thyroid gland hormone, T3 and T4 iodine is required. As the exposure of the radioactive iodine element is taking place, therefore, it will result in the deterioration of the thyroid gland. Radioactive iodine is generally used in the treatment of hyperthyroidism.
However, in normal individuals, the exposure of the radioactive iodine element results in a decrease in the level of thyroid hormones below the normal level due to the destruction of the thyroid cells. The symptoms seen can be neck tenderness, swollen salivary gland, and loss in body weight.
The thyroid gland will be mostly affected in this case. The element Iodine is
the major precursor which is involved in the formation of two hormones.

What are the phagocytes cell in the skin
Answer: The mononuclear phagocyte system (MPS), which includes macrophages and dendritic cells, has also been implicated in the regulation of skin salt homeostasis and blood pressure [35]
Explanation:
Answer:
The phagocytes cell in the skin are the monocytes, macrophages, neutrophils, tissue dendritic cells and mast cells. One litre of human blood contains about six billion phagocytes.
When pathogens are detected, the immune system produces millions of white blood cells, which fight the infection. Blood vessels near the wound expand, and white blood cells move from the vessels to enter the infected tissues. Many of these white blood cells are phagocytes which engulf and destroy bacteria.

Most physical characteristics are inherited. Scientists have discovered several genes that contribute to human fatness, particularly genes that regulate the production of specific ____________ , such as ____________ , which stimulates hunger, and ____________ , which reduces hunger.
Answer:
hormones; ghrelin; leptin.
Explanation:
Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.
Heredity refers to the transfer of traits (specific physical characteristics) from the parent of a living organism to her offspring through sexual reproduction or asexual production. Some examples of hereditary traits are dimples, tongue rolling, baldness, handedness, freckles, curly hair, color blindness, height, etc.
A gene can be defined as the complete set of hereditary instructions that is typically found in the deoxyribonucleic acid (DNA).
Over the years, scientists have discovered several genes that are known to contribute to human fatness (body weight), especially genes that are saddled with the responsibility of regulating the production of specific hormones, such as ghrelin, which stimulates hunger, and leptin, which reduces hunger.

Answer:
List three protozoan infections of the circulatory system that are transmitted by arthropods:
Malaria
Toxoplasmosis
Chagas disease (American trypanosomiasis)
Explanation:
Malaria is a prozotoan infection, that can be produced by several protozoan, in the genus Plasmodium. This Plasmodium infect red blood cells and the vector that trasmites it is the Anopheles mosquitoe. In this disease, red blood cells can have severe damage in different organs because of the hemolysis.
Toxoplasmosis is a disease caused by the protozoan Toxoplasma gondii. The main vector of them are domestic cats. When cats are infected, T. gondii oocysts is found in their feces and it can spread to humans. This disease is generally asymptomatic, except when the patient has AIDS or in pregnancy, which can be very dangerous and fatal.
Chagas disease, or American trypanosomiasis is caused by protozoan Trypanosoma cruzi and is generally transmitted to people thanks to the feces of triatomine bugs. Some of the acute symptoms include fever, vomiting, headache, and in severe cases people can develop a chronic disease. In the worst cases it can produce flaccid cardiomegaly (enlargement of the heart) leading to heart failure and death.

Biological structures are arranged based on the level of the organization. The order of organization from smallest to largest is pillar cells, lamellae, gills, respiratory system, and fish. Thus, option B is correct.
What is the level of organization?
The level of organization is the arrangement of the structures based on the level of complexity. It starts from the most simple to the most complex structures. It starts with an atom and ends in an ecosystem.
Pillar cells are the simplest level that comprises the fundamental unit made of molecules. They together make the tissues or the lamellae in the fish. The tissues or the lamellae group together to make the organ and gills.
The gills combines with the other organs to make the organ system like the respiratory system, which together with various organ system makes the fish the makes a complete organism.
Therefore, the order of the organization starts with pillar cells and ends at fish.
