Mad cow disease is caused by deformed proteins called prions. The disease is spread when meat from an infected cow is eaten. Prions can make normal proteins deform into more prions. After a few years, the brain of an infected person or cow looks like a sponge full of holes. Are prions considered organisms?
Answer:
No.
Explanation:
No, prions are not considered organisms because they are proteins that the infection to the surrounding cells and tissue. Prion is a type of protein that can change normal proteins in the brain into abnormal. Prion diseases can affect both humans and animals and spread to humans by eating infected meat products. So we can conclude that prions are not organisms, they are proteins.
How quickly does the process of excretion occur in plants?
Explanation:
Plants produce two gaseous waste products i.e. oxygen during photosynthesis and carbon dioxide during respiration. Excretion of gaseous waste in plants takes place through stomatal pores on leaves. ... Excess of water is also excreted from the plant body through the stomatal pores and from the surfaces of fruits and stems.
How did the insertion of a nucleotide in a DNA sequence result in a phenotypic change in an organism
Answer:
if the nucleotide insertion occurs within the coding region of a gene (frameshift mutation), then it will change the open reading frame (ORF) of the resulting protein and thus also will alter the phenotype of the individual
Explanation:
A mutation is any change in the DNA sequence of the genome of a cell/organism. A point mutation is a genetic mutation where a single nucleotide is inserted, deleted or changed from the original DNA sequence. The insertion of a single nucleotide in the coding region of a gene is called frameshift mutation since this nucleotide base shifts the way the DNA sequence is read. A frameshift mutation changes the meaning of the codons that follow the inserted nucleotide base and thereby protein function is generally lost, thereby also affecting the resulting phenotype associated with this protein.

The study of evolutionary relationships that includes a branching pattern showing lineages diverging is called... * 1 point
Answer:
The study of evolutionary relationships that includes a branching pattern showing lineages diverging is called phylogenetic tree
Explanation:
The phylogenetic tree is composed of,
• Lineages → These are the taxonomic groups of interest placed in the extremes of the lines called branches.
• Nodes → These are the ramification points, which are also known as divergence points. They represent the location of the most recent common ancestor.
• Root → This is the older common ancestor that all lineages share. The first one in the tree.
Two or more lineages are more related to each other if they share a recent common ancestor. This means that they all diverge from the same node.
Two or more lineages are less related to each other if they lack a recent common ancestor. This is, the node from which these lineages diverge is placed far away in the tree.
There are also different phylogenetic relationships between lineages.
• Apomorphies → Occur when the involved lineages share a trait that they inherited from their most recent common ancestor. This trait evolved for the first time in this ancestor. → This relationship is a homology.
• Plesiomorphies → occur when the involved lineages share a trait inherited from a common ancestor, but that is older concerning the present traits exhibited by other descendants of the same common ancestor. → This relationship is a homology.
• Homoplasy → Lineages share a trait that evolved independently in each group. → This relationship is an analogy.

"Grandpa, don't die!" Emma Abrams choked with deep conviction. "You mean everything to me. I can't live without you!" This was the part of the script where Emma was supposed to burst into real tears, yet her big blue eyes were like a desert. Emma tried to think of something despairing, like the time her toddling brother sliced his finger on a piece of broken glass while she was watching him, or the devastation she felt when learning that her cat had run away. These sad reflections did nothing to moisten her eyes. "Well, don't panic, Emma," she coached herself. "When it counts in the audition today, you'll cry real tears. You've just got to!"
It was difficult to study the script in the car with all of the bumps, turns, and sudden stops typical of trips into New York City, but Emma was determined to make sure that she had each line memorized word for word. She had studied every line nonstop since her agent had called with the good news. It was her first Broadway audition and her entire family had helped her to prepare. Her older sister helped her choreograph a dance, her father improvised with her by playing the part of Grandpa at the dinner table, and her little brother listened to her read her lines. No one was more constant in helping Emma realize her thespian ambitions than her mother, though. Mom was the one who accompanied Emma to her piano, voice, dance, and drama lessons each weekday after school. She went to every audition and performance with Emma, and Emma wished with all her heart that Mom was here with her now.
Emma appreciated her mother's constant companionship and support of her acting career. Her mother was always present backstage at the Dutch Apple Dinner Theater where Emma was currently starring in Annie on Friday and Saturday nights. Mom was the driving force behind her daughter's acting career, but she refused to drive in New York City. The big city frightened Mrs. Abrams and made her jittery. Since she was already nervous about Emma's big audition, Mrs. Abrams thought it best if she just stayed home. Emma tried to behave like a grown-up when her mother told her she wouldn't be going, but inside Emma felt panicky and alone.
Emma's father continued to navigate through the heavy traffic streaming into the city. As the skyline of New York City came into view, Emma started to cry. She knew she should have begged her mother to come with her but now it was too late! Her father looked into the rearview mirror and said, "Wow, honey! If you can do that during the audition, you're a shoo-in." He was genuinely impressed and didn't realize that her tears were real. Emma stared out the window, feeling sorry for herself.
Emma watched her dad hand his car keys to the parking attendant. They walked in silence for several blocks, with Emma holding her father's arm. She wanted to ask her father to come in to the audition with her, but she knew he'd be uncomfortable around a bunch of stage mothers. Emma soon found herself being escorted into a crowded lobby. She waved good-bye to her father and disappeared inside the theater.
When she emerged from the audition several hours later, Emma was exhausted but triumphant. "I don't ever want Mom to come to an audition where I have to cry again!" she declared as they left the theater together.
Knowing his daughter's flair for the dramatic, Mr. Abrams quickly said, "Now don't be angry with your mother because she couldn't come today, Emma. That's not fair."
Emma realized her father misunderstood her, so she explained that when she'd cried in the car earlier, it wasn't an act; she was genuinely upset that her mother wasn't with her. "When I went into the audition, all the other girls' mothers were there, but I was all alone. I was terrified without Mom there, so when they called on me to read my lines, I was on the verge of tears anyway. I just thought about how alone I felt without Mom there, and the tears came pouring down. It was perfect timing, and I think I just might get the part! Mom is the secret to my success." She bowed and curtsied to an imaginary audience, saying "Thank you, Thank you."
Mr. Abrams smiled and said, "I'm not sure, but I think that just this once, your mother will be extremely happy to hear that she made you cry."

Which of the following is NOT a way in which line is created?
O Dot-to-dot placements
O Use of linear objects
O Sequential placement of materials
O Use clusters of filler materials
Answer:
Use clusters of filler materials
Explanation:
A line can be defined as a one-dimensional figure that is straight, has no thickness (width) but extends infinitely in both directions.
Generally, a line can be created through the use of the following techniques or methods;
1. Dot-to-dot placements i.e distance between two points.
2. Use of linear objects: it involves the use of an object that is straight in shape.
3. Sequential placement of materials.
However, a line cannot be created through the use of clusters of filler materials.
Which of the following is an example of a feedback loop in the body of the nervous system sends a signal to produce hormones in the body produces adrenaline when a person is scared the thyroid gland reverses the action of the parathyroid gland the pancreas can be Endo crying or exocrine
Explanation:
Both the endocrine and nervous systems use chemical signals to communicate and regulate the body’s physiology. The endocrine system releases hormones that act on target cells to regulate development, growth, energy metabolism, reproduction, and many behaviors. The nervous system releases neurotransmitters or neurohormones that regulate neurons, muscle cells, and endocrine cells. Because the neurons can regulate the release of hormones, the nervous and endocrine systems work in a coordinated manner to regulate the body’s physiology.
if you remove all the water from an RBC, what's left besides a phospholipid bilayer cell/plasma membrane?)
Answer:
Salts, proteins and hormones.
Explanation:
Salts, proteins and hormones are the substances that are present in red blood cells. Plasma of the blood is composed of 90% water, salts, lipids and hormones. It is also rich in proteins such as albumin, immunoglobulins, clotting factors and fibrinogen. These substances are important parts of blood which made the blood to perform its function to transport nutrients in the body so after the removal of water, Salts, proteins and hormones are present in the red blood cell.

More than 100 years ago, Earth's atmosphere contained about 280 parts per million (ppm) of carbon dioxide. It is predicted that by the year 2050, the level of carbon dioxide in the atmosphere could reach 700 ppm, greatly increasing Earth's temperature. It has been suggested that growing more green plants would help to slow this increase. The best explanation for why increased numbers of plants would help is that plants
Answer: remove CO2 from the atmosphere during respiration
Explanation: I got the question right
Increased numbers of plants will reduce CO2 because plants use CO2 during photosynthesis.
What is photosynthesis?Photosynthesis converts light energy by phototrophs into chemical energy, then used for cellular power activities.Sugars, formed from water and carbon dioxide, store chemical energy.How do plants use CO2 in photosynthesis?Plants fix atmospheric CO2 to store energy as carbohydrates. In the dark reaction of photosynthesis, carbon dioxide is assimilated.CO2 is used in the carboxylation of ribulose bisphosphate during carbon fixation (RuBP). The reaction is catalyzed by the enzyme RuBisCO and is the first step in the Calvin cycle. It produces two molecules of 3-phosphoglyceric acid (3PGA), which is then reduced in a series of reactions to produce glucose, and RuBP is regenerated.Thus, we can conclude that during photosynthesis, plants use CO2 and reduce CO2 from the environment. Therefore, afforestation should be done.

HELP PLEASE! Choose 3 of the water quality indicators write a summary of what it is
Answer:
Explanation:
Dissolved oxygen (DO)
The DO test measures the amount of oxygen dissolved in the water. Oxygen is essential for both plants and animals, but high levels in water can be harmful to fish and other aquatic organisms.
Water temperature
Aquatic organisms are dependent on certain temperature ranges for optimal health. Temperature affects many other parameters in water, including dissolved oxygen, types of plants and animals present and the susceptibility of organisms to parasites, pollution and disease.
pH
A pH test measures the alkalinity or acidity of water. A pH of 7 is neutral, below 7 is acidic and above 7 is basic or alkaline. Acid rain, from auto exhaust or other pollutants, causes a drop in the pH. Pollution from accidental spills, agricultural runoff and sewer overflows can also change the pH.
Escherichia coli (E. coli)
E. coli is a fecal coliform bacteria that comes from human and animal waste. The Environmental Protection Agency uses E. coli measurements to determine whether fresh water is safe for recreation. Disease-causing bacteria, viruses and protozoans may be present in water that has elevated levels of E. coli. Levels of E. coli can increase during flooding. E. coli is measured in number of colony forming units. The EPA water quality standard for E. coli bacteria is 394 colony forming units per 100 mL.
