The building blocks of DNA are like alphabet letters, because they:
A. Are each associated with a particular sound
B. Can be used in a variety of languages
C. Each have an uppercase and a lowercase form
D. Spell out different instructions depending on their order
Answer: The answer is D.
Explanation: It makes the most sense and explains how both the aplhebet and DNA have simrialities.
The building blocks of DNA are like alphabet letters because they spell out different instructions depending on their order. Thus, the correct option for this question is D.
What are the building blocks of DNA?The building blocks of DNA are known as nucleotides. These nucleotides are made up of three parts. They are as follows:
A phosphate group.A pentose sugar.Nitrogenous base.These nucleotides are arranged by one another with the help of a linkage known as phosphodiester linkage. Nitrogenous base in nucleic acids like DNA includes Adenine, Thymine, Cytosine, and Guanine. In the DNA, they are represented as A, T, C, and G. Due to this, the building blocks of DNA are like alphabet letters.
Therefore, the building blocks of DNA are like alphabet letters because they spell out different instructions depending on their order. Thus, the correct option for this question is D.

What is poisonous enough to kill 100,000 turkeys? That’s the question asked by scientists who studied a mass die-off of turkeys in Great Britain. It turned out that all the turkeys had eaten peanuts from Brazil. A fungus was growing on the peanuts. The fungus produced a dangerous poison called aflatoxin. Aflatoxins cause stomach pain, lung failure, cancer, and death in people and animals.
Farmers make a great effort to prevent fungi from growing on their stored crops. In a pile of grain or nuts, fungi have plenty of food and living space. The best way for farmers to prevent fungi from growing is to make sure there is not enough for fungi to survive and grow.

In many parts of the world, there is a rock layer rich in the metal iridium. Iridium is very rare on Earth, but it is relatively common in meteorites and other debris that comes from outer space. All occurrences of this iridium layer are from the same geologic epoch, at the very end of the Cretaceous. Most of the fossils in rock layers below the iridium layer, including dinosaur fossils, do not appear in layers above the iridium layer.
Based on this evidence from the rock and fossil record,
A.
meteoroids and other space debris did not impact the Earth at the end of the Cretaceous.
B.
an asteroid impact likely caused a mass extinction at the end of the Cretaceous.
C.
meteorites and other space debris no longer contain the metal iridium.

B.
an asteroid impact likely caused a mass extinction at the end of the Cretaceous.

Moving your limb through a full 360 degree circle is called what*
Rotation
Circumduction
Flexion
Extension
Answer:
rotation
Explanation:
circle is 360 degrees
Moving your limb through a full 360 degree circle is called rotation of your limb.
What is rotation?Rotation is the process of moving an object or a body from a central position, through the circumference of that position.
This type of motion is usually 360 degrees movement because it involves a complete circle or turn.
Thus, moving your limb through a full 360 degree circle is called rotation of your limb.

In cystic fibrosis, an important protein destined for the plasma membrane never makes it beyond the Golgi complex. This protein is necessary for Na and Cl- transport and is critical for maintaining mucous secretions of the appropriate consistency. Devise an explanation for why this may occur.
Answer:
The correct answer is - Golgi apparatus marks or tags on this protein as incorrect or dysfunctional tags which then prevents it from transported to the membrane.
Explanation:
The role of the Golgi apparatus is to process and package the proteins produced and come from ER and transfer them to the plasma membrane in order to transfer them to their target sites.
The Golgi apparatus marks or tags the proteins that are incorrect or dysfunctional, in order to prevent these proteins from transporting to the plasma membrane and harm the membrane. In CF, the case is similar as the Golgi apparatus tags these proteins as incorrect or dysfunctional.

Scientists were investigating a pond of water found deep in a South American cave along the Yucatan Penisula. They obtained many samples which they took back to their lab. After much testing, they found that the water has an acidic pH of 3. Another much more surprising discovery was that a new species of a unicellular organism was present in the samples. The organism was observed with a microscope and found to not have a bound nucleus or organelles. To which Domain would this organism be classified?
Group of answer choices
Bacteria
Protista
Eukarya
Archaea
Answer:
Bacteria
Explanation:
Bacteria is the correct answer because it lacks organelles or a nucleus.
Protista is not the correct answer because they have organelles and a nucleus.
Eukarya is not the correct answer because they have organelles and a nucleus.
Archaea is not the correct answer because they have organelles and a nucleus.
Bacteria is the correct answer because it lacks organelles or a nucleus. Protista is not the correct answer because they have organelles and a nucleus.
What is Bacteria?Eukarya is not the correct answer because they have organelles and a nucleus. Archaea is not the correct answer because they have organelles and a nucleus.
Microbes known as bacteria have simpler cell structures than many other types of creatures. One DNA loop serves as their command center and houses all of their genetic data. Instead of a nucleus, some bacteria have an additional ring of genetic material called a plasmid.
Genes that offer the bacterium a competitive edge over other bacteria are frequently found in the plasmid. For instance, it might have a gene making the bacterium immune to a specific antibiotic.
Therefore, Bacteria is the correct answer because it lacks organelles or a nucleus. Protista is not the correct answer because they have organelles and a nucleus.

Hannah and Becca are fraternal twins. They are both athletic. Hannah is a swimmer, and Becca is a runner. Which sister would have denser bones?
According to the question, Hannah would have denser bones because her bone would get heavier due to water absorption through epithelial cells.
What is Bone density?Bone density may be characterized as a type of measurement that significantly involves the accumulation certain amount of minerals contained in a certain volume of bone. This measurement is generally used to find out and treat serious bone loss, called osteoporosis.
When an individual is practicing in a swimming pool constantly for a longer period of time, it is observed that his/her bone density must be increased as compared to those who are running or performing other types of athletic activities.
Therefore, according to the question, Hannah would have denser bones because her bone would get heavier due to water absorption through epithelial cells.

a. True
b. False
Answer:
a. True
Explanation:
Bruce Wallace was a professor emeritus of genetics who performed many population studies. He worked in 1958 at the University of Cornell as a professor of genetics. In 1963, he performed a population study wherein the recessive allele It was at a frequency of 0.5. The population was propagated for 10 generations and the frequency of It for each generation was determined.
The result of this study showed that lt/lt died without reproducing, whereas, individuals with genotype +/+ were normal.
