What are the building blocks of proteins? If all proteins are made of the same
building blocks, how can there be so many different types of proteins with different
functions?
Answer:
The basic building blocks of proteins are called amino acids. In proteins, amino acids are arranged into a linear molecule called a polypeptide chain. Some proteins only consist of a single polypeptide chain while more complex proteins are made out of multiple polypeptide chains bonded together.
Explanation:Proteins are formed out of long linear molecules of amino acids called polypeptide chains. The identity and function of a protein are determined by its sequence of amino acids and the 3-D structure of its polypeptide chains. Amino acids are stored in DNA in the form of sequences of nucleotide bases.

In a zoo located in a warm region, which should be included in the polar bear exhibit?
A food bowl with fruit
B hot, bright lights
C cold-water pool
D tall palm trees
Answer:
C Cold - Water pool
Explanation:
The two polar bear habitats are very different and provide unique experiences for the bears to investigate. To keep the bears cool, the floors in the Ice Cave are chilled by cold water running underneath and their pools are kept between 50 - 60°F. Keepers train the bears to voluntarily take part in preventative health care.

The first line of defense involves which structure(s)?
OT-cells
O skin
O blood
OB-cells
Answer:
skin
Explanation:
The skin is vital for our general health and well-being. In addition to acting as the body's first line of defense against bacteria and viruses, healthy skin also maintains fluid balance and helps regulate body temperature. She is very sensitive, she recognizes the slightest touch as well as pain.
As an outer layer that we can see and touch, the epidermis protects us from toxins, bacteria, and fluid loss. It consists of 5 sublayers of keratinocyte cells. These cells, produced in the deepest inner, basal layer, migrate to the surface of the skin. As they do so, they mature and go through a series of changes.
Predation is when a predator feeds on another organism, which is referred to as the predator's prey.
True
False
Answer:
True
Explanation:
Predation is another mechanism in which species interact with each other. Predation is when a predator organism feeds on another living organism or organisms, known as prey. The predator always lowers the prey's fitness. Also, a predator is an organism that eats another organism. The prey is the organism which the predator eats. Some examples of predator and prey are lion and zebra, bear and fish, and fox and rabbit.

B. The rapid growth of prokaryotic cells generates more viruses.
C. Unlike eukaryotic cells, prokaryotic cells do not have a nucleus.
D. The cell wall in prokaryotic cells is a less effective barrier.
Answer:
C
Explanation:
Because eukaryotes have membrane bound nucleus where they store their generic information

Which of the following is found in the cells of
fungi but NOT of archaebacteria?
A ribosomes
B cell membrane
C DNA
D nucleus
Answer: im 90% sure its (d)
According to the question option "D" Nucleus is found in the cells of fungi but NOT of archaebacteria.
What is the difference between fungi and archaebacteria?
Fungi cell walls usually are constructed of chitin whereas Eubacteria cell walls have peptidoglycan.
Archaebacteria do not have either substance, although the cell walls of some archaebacteria contain a substance similar to peptidoglycan.
Thus, the option "D" Nucleus is found in the cells of fungi but NOT of archaebacteria.

Explanation:
A male cardinal’s red color is an example of a trait affected by natural selection. The females of the species choose mates based on the vibrant colors of the males’ feathers. If females begin using different criteria than feather color when they choose mates, what would most likely happen to the color of the male cardinals over time?
increased variation in the shades of red because there is no advantage in one specific color
increased variation in the shades of red because the cardinals try different ways to impress the females
decreased variation in the shades of red over time because no form of the trait is advantageous
decreased variation in the shades of red after a single generation
Answer:
decreased variation in the shades of red over time because no form of the trait is advantageous
Explanation:
If the vibrant red feathers are no longer used to attract mates, then it is no longer useful to the males, so it will cease to exist.
Answer:
C. decreased variation in the shades of red over time because no form of the trait is advantageous

prokaryotic cells.
Eukaryotic cells are usually smaler than prokaryotic cells
Answer:
Eukaryotic cells are believed to be evolved more recently than prokaryotic cells.
Explanation:
The statement about eukaryotic cells is NOT true - Eukaryotic cells are usually smaller than prokaryotic cells
Cells are fundamental units and are mainly two types eukaryotic cells and prokaryotic. There are various structural and functional differences and similarities found in them.
Prokaryotes and eukaryotic cells have the following difference:
Prokaryotic cells lack a true nucleusProkaryotic cells lack other membrane-bound organelles.Eukaryotic cells have more organelles, enzymes, and molecules, therefore, prokaryotic cells are simpler.Prokaryotic cells are comparatively smaller than eukaryotic cells.Prokaryotic cells are evolved before eukaryotic cells.Thus, the statement about eukaryotic cells is NOT true - Eukaryotic cells are usually smaller than prokaryotic cells

Explain how specific proteins are formed from a strand of mRNA.
Answer:
During translation, ribosomes move along an mRNA strand, and with the help of proteins called initiation factors, elongation factors, and release factors, they assemble the sequence of amino acids indicated by the mRNA, thereby forming a protein.
Explanation:
Answer:
Explanation:
Los ARN mensajeros, también conocidos como ARNm, son uno de los tipos de ARN que se encuentran en la célula. Éste en particular, como la mayoría de los ARN, se sintetiza en el núcleo y luego se exporta al citoplasma, donde la maquinaria de traducción, la maquinaria que realmente fabrica las proteínas, se une a las moléculas de ARNm y lee en ellas el código para producir una proteína específica. Así que en general, un gen, el ADN de un gen, puede ser transcrito en una molécula de ARNm que puede acabar dando lugar a una proteína específica.
