Animals that live exclusively by eating other animals are unable to use carbohydrates to fuel their life processes. Select one: True False

Answers

Answer:

False

Explanation:

All the animals use carbohydrates as their primary source of energy. Glucose is the molecule which is oxidized by all animals in their cell and energy released by this oxidation is used by animals to perform necessary metabolic activities important for cell survival. ATP is produced by glucose oxidation which is a cellular form of energy.

Many organs like liver, muscle have carbohydrates which are eaten by carnivores which means these animals are able to use carbohydrate to fuel their life process. Therefore the given statement is false.

Some digestive products, such as water and electrolytes, will be absorbed by diffusion. They diffuse from an area of ____________ concentration in the intestinal lumen to an area of ____________ concentration in the cell.

Answers

Answer: Higher concentration; Lower concentration.

Explanation: The food that we eat undergoes digestion and breaks down into smaller components.

These small components of the food needs to be absorbed first by the process of diffusion.

The water molecules along with the electrolytes are absorbed from an area of its higher concentration in the lumen is transported to area where its concentration is very low.

Hence, the correct answer is diffusion, which is responsible for the transportation of products from one place (higher concentration) to another parts (lower concentration)in the body.

In mitosis, when do the sister chromatids align with centrosomes in the cells? A. Anaphase
B. Telophase
C. Metaphase
D. Interphase

Answers

Answer:

C. Metaphase

Explanation:

In mitosis, the sister chromatids align in the "center" of the cell as the centrosomes are at the poles of the cell. They do this, moving on to the next phase Anaphase - where they will eventually split. Interphase isn't part of mitosis - it describes the period in which the cell is just growing and copying DNA.  If you textbook says it is, then thats ok, sometimes its included as part of it (even though technically its not).  

Answer: the answer is not metaphase.

Indicate whether the following statements about DNA fingerprinting are true or false.1. DNA fingerprinting compares mitochondrial DNA samples. 2. DNA fingerprinting compares X chromosomes. 3. DNA fingerprinting decreases the necessary sample size.4. DNA fingerprinting increases the amount of evidence.5. DNA fingerprinting compares Y chromosomes.

Answers

DNA fingerprinting

Explanation:

  • DNA fingerprinting compares mitochondrial DNA samples."True" statement because this technique is used for analysis of paternity cases by the forensic scientist to examine the child's DNA with parents.
  • DNA fingerprinting compares X chromosomes. "False" statement because technique is used for DNA and Y chromosomes loci not for compare the x chromosome.
  • DNA fingerprinting decreases the necessary sample size. "true" statement this is because through the use of this tecnique DNA sample is decrease due to the use of PCR, RFLP, methods it will be divided into small fragments.
  • DNA fingerprinting increase the amount of evidences. "False" statement because this technique decrease the amount of sample as discuss in step 3 of the answer.
  • Dna fingerprinting compares Y chromosomes. "True"  statement because in DNA databases this technique is used to locate the y chromosome loci. to identify the segment of DNA
  • Hence, the answer is "True,false,True,false,True".

Answer:

TRUE DNA fingerprinting compares mitochondrial DNA samples.

Random Questions
A lady in a faded gingham dress and her husband, dressed in a homespun threadbare suit, stepped off the train in Boston, and walked timidly without an appointment into the president's outer office. The secretary could tell in a moment that such backwoods, country hicks had no business at Harvard and probably didn't even deserve to be in Cambridge. She frowned. "We want to see the president," the man said softly. "He'll be busy all day," the secretary snapped. "We'll wait," the lady replied. For hours, the secretary ignored them, hoping that the couple would finally become discouraged and go away. They didn't. And the secretary grew frustrated and finally decided to disturb the president, even though it was a chore she always regretted to do. "Maybe if they just see you for a few minutes, they'll leave," she told him. And he sighed in exasperation and nodded. Someone of his importance obviously didn't have the time to spend with them, but he detested gingham dresses and homespun suits cluttering up his outer office. The president, stern-faced with dignity, strutted toward the couple. The lady told him, "We had a son that attended Harvard for one year. He loved Harvard. He was happy here. But about a year ago, he was accidentally killed. And my husband and I would like to erect a memorial to him, somewhere on campus." The president wasn't touched—he was shocked. "Madam," he said gruffly, "We can't put up a statue for every person who attended Harvard and died. If we did, this place would look like a cemetery." "Oh, no," the lady explained quickly, "We don't want to erect a statue. We thought we would like to give a building to Harvard." The president rolled his eyes. He glanced at the gingham dress and homespun suit, then exclaimed, "A building! Do you have any earthly idea how much a building costs? We have over seven and a half million dollars in the physical plant at Harvard." For a moment the lady was silent. The president was pleased. He could get rid of them now. And the lady turned to her husband and said quietly, "Is that all it costs to start a University? Why don't we just start our own?" Her husband nodded. The President's face wilted in confusion and bewilderment. And Mr. and Mrs. Leland Stanford walked away, traveling to Palo Alto, California where they established the University that bears their name, a memorial to a son that Harvard no longer cared about. adapted from "Appearances" by Kasha Linka 8 What is ironic about the situation? A. The president used to know them from the town he was raised in. B. The couple turns out to be related to the secretary's family. C. Even though the couple is poorly dressed, they are millionaires. D. The couple is better educated than the president or the secretary.
