Answer:
True
Explanation:
Most the amino acid are of L configuration. Antimicrobial peptides consists of D amino acids (D amino acid occur naturally). D amino acids are also found in walls of microorganism. Antimicrobial peptides is released by species including bacteria, fungi etc.
For example - Bacteriocin, peptaibols, plectasin etc.

Why is a pasture-type system is
more labor intensive than
controlled systems?
A. There is greater maintenance of the
equipment.
B. There is greater need to handle diseases.
C. There is greater area to cover to observe and
manage the animals.
D. There is greater cost of feed per animal.
Answer:
The correct option is C.
There is greater area to cover to observe and
manage the animals.
Explanation:
This is because pasture type system refers to a large area of land where grasses are grown and animals are allow to graze the area of land to obtained nutrients. In this system there is large area of land where animals are well observed while feeding in order to prevent the risk of loss and attacks.
What happens after Telophase?
&
36/86

C
Answer:
The chromosomes begin to uncoil, which makes them diffuse and less compact. Along with telophase, the cell undergoes a process called cytokinesis that divides the cytoplasm of the parental cell into two daughter cells.
a radioactive element has a half-life of 3,000 years. if a sample of this element begins with a mass of 60 grams, how long would you have to wait for the mass to decrease to 15 grams
Answer:
N = 60 g
Half life : N/2 = 3000
N/4 = 15 g

- Which occurrence is the result of the cell cycle in unicellular organisms?
A. cell repair
B. cell growth
C. cell replacement
D. cell reproduction
Answer:
D
Explanation:
Cell reproduction is the result of the cell cycle in unicellular organisms. The correct option is D.
What is cell reproduction?Cells split to produce multiple cells with similar, if not identical, contents. This process is known as cellular reproduction.
Nuclear division during mitosis produces two somatic cells that are genetically identical to the parent cell and have the same genetic complement.
Asexual reproduction in prokaryotes takes the form of cell division in unicellular organisms.
When an organism splits in half, it creates two totally distinct daughter cells, a process known as binary fission. The daughter cells are identical to the parent cells genetically.
Most of the time, Paramecium reproduces asexually via budding, however in poor circumstances, they produce sexually.
Unicellular organisms have a variety of asexual reproduction strategies, including multiple fission, fragmentation, and budding.
Thus, the correct option is D.

how does shell color work to protect the egg from sunlight?
Answer:
Birds that live in cool climates lay darker eggs, as darker colors absorb more heat from the sunlight
Birds that live in hotter climates lay lighter eggs to prevent the egg from overheating.
The pigmentation acts to thermo-regulate the internal temperature of the egg, acting as a buffer between the embryo and the outside world. It does this by preventing overheating of the egg, through reflecting the sunlight off the pigmentation, rather than allowing it to be absorbed through the shell
For tetracycline , describe an experiment that you could
use to determine if a bacterial sample taken from a person was
resistant to your antibiotic. Be sure to describe all steps of the
experiment including your independent, dependent and control
variables.
Answer:
penicillin was the first antibiotic discovered. Alexander Fleming discovered it in 1928. It was used widely during World War II. However, the sulfonamides were the first antibiotic class used clinically (in the 1930's). The discovery of antibiotics revolutionized medicine by making once-deadly infections treatable. There are now hundreds of antibiotics, classified into several categories. These antibiotic classes include:

The prolonged increase in heart and breathing rates during the snow skiing trip was probably a result of:______
a. activation of the sympathetic autonomic nervous system by the new experience.
b. activation of the parasympathetic autonomic nervous system by the new experience.
c. hypoxia caused by insufficient blood hemoglobin concentration to supply oxygen for exercise at the low oxygen pressure found at high altitudes.
d. depressed core body temperature (hypothermia) caused by exposure to cold temperatures at high altitudes.
Answer:
The correct answer is - option C.
Explanation:
Skiing generally happens on higher altitudes such as mountains. It is known that there is less oxygen is available at higher altitudes. There is low oxygen pressure at such height.
The prolonged increase in heart and breathing rate is due to less oxygen available for the cells. This condition is known as hypoxia caused by insufficient blood hemoglobin to supply oxygen for physical activities at higher altitudes.
if an earthworm is 18mm long and is photographed and the picture is magnified 2.5x how long will it be in the picture?
Answer:
The earthworm will be 45 mm long in the picture
Explanation:
From the problem, we can take the original size of the earthworm to be 18mm.
Magnification can be obtained using the formula:
magnification = observed size/ original size.
Recall, we are given that the magnification is 2.5.
Hence, can evaluate the size in the picture to be
2.5 X 18mm = 45mm
