Answer:
Monoclonal antibodies (mAbs) are produced by introducing an antigen to a mouse and then fusing polyclonal B cells from the mouse's spleen to myeloma cells. The resulting hybridoma cells are cultured and continue to produce antibodies to the antigen.

The pH of a solution determines the charge of certain R groups. The pH of pineapple fruit ranges from 3.5 to 5.2. Predict the effect on the activity of bromelain if it is used in a product with a pH of 11.
Answer:
The activity of Bromine will reduce
Explanation:
Bromine is found in pineapple stem with pH range of 3.5- 5.2 this implies that the environment where bromine is found is acidic hence when taken to a product whose pH is 11 which is basic then its performance will be low because its can only function well in an acidic medium.
pH ranges tell whether a substance is acidic, basic or neural.
Acid range from 3.5-6
7- neutral
8 above is basic
This is about knowing the behaviour of some elements in different PH Values.
The activity of bromelain will decrease in a product with a pH of 11. .
We are told that the PH of pineapple fruit is of the range of 3.5 - 5.2. In reality, this also includes it's stems and the plants as well. This falls into the acidic range because PH less than 7 is acidic.Now, these stems, plants and fruits of pineapple usually contain bromelain. This implies that bromelain does its' work in an acidic environment since pineapple has an acidic PH.If bromelain is used in a product with a PH of 11, it means it is being used in a basic environment because a PH greater than 7 indicates a basic nature. This means bromelain will not function as well as it did in the acidic environment and as such the activity of bromelain here would decrease.We can now conclude that the activity of bromelain will decrease in a product that has a PH of 11.

Select the living organisms that will decrease as a result of the loss of coral in the food web.
Answer:
Butterfly fish, Triggerfish, parrotfish, and sharks
Explanation: Because the first three fish listed feed on coral, their populations will decrease if coral is eliminated because that means there will be less food to go around for the populations to consume. Many will die out. If those fish die, there will be less of them for the sharks to eat, causing the shark population to decrease as well.
What is the main function of the cell membrane of a cell?
A. to exchange nutrients and the cells waste with the external environment
B. to limit the size that cell can reach
C. To organize the cell's internal contents
D. to protect the cell from harmful substances in the environment
Answer:
D. to protect the cell from harmful substances in the environment
Explanation:
Cell membrane is also known as plasma membrane is a biological membrane that differentiate the internal organelles of the cells from the outside environment. Cell membrane is made up of phospholipid bilayer with embedded proteins.
The main or primary function of cell membrane is to protect cell from harmful substances in the environment as it is the outer convering of the cell. cell membrane regulates movement of substances in and out of cells which restricts entry of harmful substances and hence called as selectively permeable membrane.
Hence, the correct option is D.

The high temperature on Friday was 8 degrees above zero. The low temperature was 3 degrees below zero. Which expression gives the average of the low and high temperatures?
a
Left-bracket negative 3 + (negative 8) right-bracket divided by (2) Right-bracket
b
(negative 3 + 8) divided by 2
c
(negative 3 + 8) divided by (negative 2)
d
Negative (3 + 8) divided by 2
Answer:
B
Explanation:
The negative goes by the 3 because it is 3 degrees below zero. To find averages, you add the numbers and divide by how many numbers there are. in this case, it would be (-3+8)/2

A. Some inherited genetic mutations can be good for the offspring.
B. Different genetic mutations cause few forms of cancer.
C. Somatic mutations can be inherited from parents or acquired during life.
D.Genetic mutations that cause diseases are always passed on to offspring.
Answer:
A genetic mutation is a random change in the DNA that is passed on further generations of cells and or organisms. Genetic mutations are accidental changes in the DNA in the germ cells or early in the formation of the embryo.
Explanation:
Some inherited genetic mutations can be good for the offspring.
What is mutation?"It is a change in the structure of a gene."Gene is a structural and functional unit of hereditary.It is caused due to addition, deletion or copying of single base pairs of DNA.The mutation that occurs in somatic cells (cell other than stem cells or s ex cells) are not transferred from parent to offspring.A mutation should occur in s ex cell, in order for it to pass down to the offspring. So, the mutation that cause disease if occurs in somatic cell will not be passed to the offspring.The mutation can sometime result in the production of new proteins that are beneficial in nature.Not all the genetic mutation can cause cancer.Hence, the correct option is A. Some inherited genetic mutations can be good for the offspring.
