Biology
1 answer:
SashulF [63]4 years ago

Answer:

Organelles

Explanation:

Living cells of organisms contain structures within them that perform specific functions for the cell. These structures are called ORGANELLES. Organelles are organ-like structures that are specific about their function in a cell.

Both the cells of prokaryotes and eukaryotes possess organelles, however, the organelles in eukaryotes are bounded by a membrane e.g mitochondrion, chloroplast etc. while those of prokaryotic cells are not bounded by a membrane.

The organelles inside a cell can be seen with the aid of an electron microscope. Examples of organelles are chloroplast (functions in photosynthesis), mitochondria (functions in production and storage of cellular energy), ribosome (functions in protein synthesis) etc.

vaieri [72.5K]

virus being a none living organism outside a living cell makes it none living. to me, at this age, to make a living virus to go back to not living, is to subject the infected cells under high treatment or damage the cell totally.

Of the answers below, what is the smallest nucleotide sequence that could code for a protein with 300 amino acids?
ololo11 [35]
The nucleotide sequence would have to have 900 nucleotides in order to code for a protein of 300 amino acids. When translating RNA into proteins, RNA is read 3 bases at a time. Each group of 3 bases is a codon, and each codon codes for an amino acid. When read, the proper amino acid is added to a growing chain of amino acids, which will be folded to become a protein.

Therefore, 300 amino acids * 3 nucleotides per amino acid = 900 nucleotides.

The set of all populations inhabiting a certain area is called a(n):
zheka24 [161]
A community refers to the total number of populations that inhabit a specific location or area. This is part of the levels of organization of life. Arranged from the least complex to most complex it falls 8th in the category. Below are the organization of life:<span>

a. Organelles - the basic part of a living organism. It refers to the different structures of the cell, whether prokaryotic or eukaryotic. (Ex. Mitochondria, nucleus)
b. Cells - building blocks of life that are composed of different molecules responsible for the function of an organism. (Example: prokaryotic, eukaryotic cells)
c. Tissues - combinations of cells that carry out a specific function in an organism. (Example: Human skin)
d. Organs - collections of tissues that perform specific functions. (Ex. heart, lungs)
e. Organ Systems - composed of interconnected organs that function as a whole. Many organisms, particularly mamamals, are composed of organ systems. (Ex. respiratory, circulatory systems)
f. Organisms – individual entities that specifically make-up a population. (Ex. Each tree in the forest is an organism, each animal in sea is an organism)</span>
g. Population – species living within a specific location. It could be the same or different species that inhabit a place. (Ex. Birds are species in the forest as well as bears)
h. Community – refers to the total number of populations that inhabit a specific location. (Ex. All of the trees, insects, birds that inhabit the forest are a community)
i. Ecosystem – consists of all living things that function together as a group which also includes the non-living parts of the environment. (Ex. Rain water, nitrogen in the soil)
<span>j. Biosphere – the highest organization of life that consist of all the collection of ecosystems in the planet. It includes the land, air, water, even the atmosphere of the planet. </span>

When cells perform photosynthesis, they transform energy from one form to another, what takes place during photosynthesis?
Oxana [17]

During photosynthesis, solar/light energy from the sun is transformed into C6H12O6, or glucose (chemical energy). Photosynthesis is defined as the process by which green plants and some other organisms use sunlight to synthesize foods (glucose) from carbon dioxide (CO2) and water (H20). Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen (O2) and glucose.
