The decimal reduction time (DRT) to kill 90% of cell present for autoclaving a culture is 1.5 minutes. How long would it take to kill all the cells if 106 cells were present? What would happen if you stopped the heating process at 9 minutes?
Answers
Answer:
10.5minutes
Explanation:
DRT = 90%
Cells present = 10^6
Autoclaving = 1.5 minutes
Solution:
10^6(1.5)10^5(1.5)10^4(1.5)10^3(1.5)10^2(1.5)10^1(1.5)10^0(1.5)0=10.5
it would take it approximately 10.5 minutes to kill 10^6 of the cells.
If i should stop the heating process at 9 minutes this would have effect on some of the microbes as they are still present with 1 bacterium left which makes it not efficient.

a. What is the major evolutionary advantage to producing an amnion?
b. What does that mean for embryonic development for the animal phylum as compared to the animal phyla?
Answers
WHAT IS THE MAJOR EVOLUTIONARY ADVANTAGE TO PRODUCING AN AMNION?
The main evolutionary advantage of producing an amnion is that the embryos of the amniotic membrane,the amniotes are made available with their own aquatic environment,this in-turn resulted to a lesser dependence on water for it's maturation and development therefore allowing or giving room for the amniotes to branch towards environments that are drier.
WHAT FOES THAT MEAN GOR EMBRYONIC DEVELOPMENT OF THE ANIMAL PHYLUM AS COMPARED TO THE ANIMAL PHYLA?
The embryonic development of animal phylum is also known as embryogenesis.
It is the development of the embryo from the point of fertilization of an egg,(the ovum) by a sperm cell ,this makes the fertilized egg a diploid cell otherwise known as a zygote.
This zygote undergoes mitosis,a mitotic division known as cleavage and a differentiation resulting in a multicellular embryo.
This embryonic development of animal phylum comprises of 36 animal phyla.
Which distribution pattern in species can be considered the most easily measurable
Answers
Answer:
local endemics
Explanation:
The most common distribution pattern in species can be considered by their geographical distribution, as different species get distributed as per their climate and the different regions that suit them the most.
What is the significance of the geographical distribution?It is significant because they differ in different parts of the world and provide suitable climatic and other environmental conditions for various animals, plants, and microorganisms to live and evolve. Its significance can be seen in the difference between the life forms in the temperate area and those in the Antarctic area.
Hence, the most common distribution pattern in species can be considered by their geographical distribution, as different species get distributed as per their climate and the different regions that suit them the most.

all of these
Answers
Answer:
phospholipid
Explanation:
Phospholipids, triglycerides, fats, and oils are examples of a lipid. Therefore, option D is correct.
What are lipids?Fatty, waxy, or oily molecules are referred to as lipids. They are soluble in organic solvents but insoluble in polar solvents like water. Steroids, phospholipids, oils, and waxes are examples of lipids. They are usually referred to as fats and oils.
Since lipids may be broken down to provide significant amounts of energy, one of their primary biological purposes is the storage of energy. The structural elements of cell membranes and a number of the body's messengers and signaling molecules are also formed by lipids.
Cell membranes, cholesterol, blood cells, and the brain are just a few places where they can be found in the human body.

How does the control group setup in an experimental differ from the other setups in the same experiment?
Answers
Answer:
A control group setup in an experiment is used to see if there are other variables in play during the experiment. Say I was to test which type of blood is a shark's favorite, my control would be putting red paint in one of the set ups to see if the shark is just interested in the red color of blood, instead of the other types of blood.
Explanation:
Answer:
The control group does not receive the independent variable during the experiment.
Explanation:
The group that will receive the independent variable during the experiment is the experimental group. The dependent variable is what you will measure as a result. The control group is not receiving the independent variable during the group, as it is what you're measuring the experimental group to.
