Answer: The question is incomplete,below is the complete question.
What are the terms describes the dna–protein complexes that look like beads on a string?
A) Chromatin
B) 30-nanometer fibre
C) Histones
D) Nucleosome
The correct answer is option D
Explanation: A Nucleosome is the basic fundamental unit of a DNA, and the fundamental sub-unit of a Chromatin.
The Nucleosome is the basic packing unit of DNA,it is built from histone proteins. A nucleosome is made up of 8 histones proteins resembling a thread wrapped round a spool.
The smallest bundle of DNA is known as a Nucleosome,a Nucleosome is produced through interaction between DNA and histone proteins.
Answer:
B., D., A., A., C., D., D., A., D., C.
Explanation:
If the statement is asking whether it is true or false, the
answer is true. The body can make its own lipid because of the food that we eat
and also because it is found in the body where it is located in the tissues and
the cells. It does compose of ring structure as it has multiple rings which are
considered essential and the lipids are considered to be a part of a cell
membrane.
The correct answers are C. Amount of rainfall, and D. Wind speed.
Explanation
Radars are instruments that were created by humans to detect objects, people, places, among others, through signals. Radars are devices used in different fields such as war, aviation, climatology, geography, among others. One of the best known is the Doppler radar, which is a climatological tool that is used to detect the intensity, size, quantity, and direction of rainfall. Likewise, rainfall is influenced by the direction and speed of the wind, data that can also be obtained using this tool. One of the purposes for which this object was created was the early detection of natural phenomena related to rains, and winds such as hurricanes, electric storms, hail, among others. Therefore, the two objects that scientists can obtain with a radar are C. Amount of rainfall, and D. Wind speed.
If a bacterium uses ammonia as an energy as well as electron source, it is classified as lithotrophic chemotrophic.
<h3>Descriptive terms for lithotrophic
chemotrophic:</h3>
Humans, fungi, and also many prokaryotes are chemotrophs that get their energy from organic chemicals. Lithotrophs are chemotrophs that obtain energy from inorganic substances such as hydrogen sulfide (H2S) as well as reduced iron. Lithography is a microbiological phenomenon that is unique in the globe.
<h3>What is the difference between chemoautotrophs and chemolithotrophs?</h3>
Chemotrophs are creatures that get energy from their surroundings by oxidizing electron sources. These compounds might well be organic (chemoorganotrophs) or inorganic (chemoorganotrophs) (chemolithotrophs). The term chemotroph is used in contrast to phototroph, which uses solar energy.
