The correct answers are 1. Using stem cells to treat disease, and 3. Diagnosing genetic diseases.
Explanation
Biotechnology is a science that covers different areas such as chemistry, biology, and technology, to improve or facilitate procedures related to living organisms by manipulating living or parts of these in areas such as agriculture, medicine, and pharmacy. In the area of medicine, biotechnology is in charge of working with DNA to improve people's health. Also, it is in charge of investigating the cells to know in depth the problems that trigger diseases or genetic problems. Another use of biotechnology in medicine is through the use of stem cells in treatments for self-renewal or regeneration of damaged tissues. So, the correct answers are 1. Using stem cells to treat disease, and 3. Diagnosing genetic diseases.

-Production of CO2
Answers
Answer:
Light dependent reactions
Explanation:
DPIP stands for Dichlorophenolindophenol. It is a chemical compound that is used as a redox dye.
DCPIP is blue when it is oxidized DCPIP is colorless when it is reduced.
DCPIP measures the rate of photosynthesis. The redox dye is decolorized by chemical reduction when it is exposed to light in the process of photosynthesis.
DPIP was used in the photosynthesis lab to measure the light dependent reactions.

You prepare an agar plate by spread plating & place an antibiotic disk in the middle of the plate. After incubating for a day at 37 degrees C, there are no bacteria on the plate. Which of the following is NOT a reasonable interpretation of what might have happened?
O The bacteria in the culture tube were already dead when you made the plate
O The medium used was defective and provided no nutrition for the bacteria
O The bacteria grew all over the plate but were then killed by the antibiotic
O The spreading tool was too hot when spreading the bacteria
Answers
Answer:
A.The bacteria in the culture tube were already dead when you made the plate
Explanation:
Antibiotics are the chemical substance used to kill or stop the growth of bacteria and some other microorganism.
Antibiotics are added to agar plate during experiment for the selection of only those bacteria with resistance to that antibiotic.
There can be several interpretation for the absence of bacteria such as:
The bacteria grows on the nutrients in the medium but due to defective medium they were unable to grow and die.It may also happen bacteria might have grown in all over the plate but due to the action of antibiotic, all the bacteria got killed.Tool used for spreading might kill bacteria as it was hot and bacteria may not be able to tolerate the excessive heat and die.Hence, the only not reasonable interpretation is bacteria in the culture tube were already dead when you made the plate.
So, the correct option is A.
In Guinea pigs, short hair (S) is dominant over long hair (s), and black coat color (B) is dominant over
albino (b). Both genes assort independently. A female of a true breeding line with a black coat and long

phenotypes of the F1 generation? Explain. (b) If F1 is mated, which percentage of the offspring will be
homozygous for both characters? Give all genotypes and phenotypes of these homozygotes.
Answers
Answer:
Explanation:
Short hair (S) is dominant over long hair (s), and black coat color (B) is dominant over albino (b).
A female of a true breeding line with a black coat and long hair is mated with a short haired albino male (also from a true breeding line)
parents genotype BBss x SSbb
gametes Bs x Sb
F1 generation geenotype BbSs
Phenotype- They are all with black coat and short hair
Mating of F1 BbSs x BbSs
Percentage of offspring homozygous for both characters:
Bb x Bb Ss x Ss
BB Bb Bb bb SS Ss Ss ss
1/4 1/4 1/4 1/4
1/4*1/4 = 1/16 = 0.0625 = 6% for each homozygous characters (BBSS-6% and bbss-6%)
The genotypes of the homozygotes are BBSS and bbss
The phenotype of BBSS is black coat with long hair
The phenotype of bbss is an albino with short hair

Answers
Answer:
Conservationists are responsible to preserve or improve the biodiversity in ecosystem. Many wildlife sanctuaries are made to protect the biodiversity. There are several ways by which conservationists accomplish their aim such as monitoring populations of organisms to detect changes and promoting importnce of wildlife.
Two main challenges conservationists will face while monitoring population of organisms in wild are:
weather conditions may not support the monitoring equipments or clothing.Wildlife animals are dangerous and can cause harm.Hence, conservationists face the above challenges while dealing with wild.
Answer:
One challenge is cost. To effectively monitor populations in the wild, scientists need special equipment such as cameras, computers, and GPS monitoring equipment. Another challenge is accuracy. It’s impossible to count every single organism in an ecosystem, so scientists often work with estimates.

Jaden’s mass is 50 kilograms. His weight on Earth is
Answers
Answer:
Weight of the Jaden on earth is 490 N.
Explanation:
Formula
w = mg
Where w is the weight of an object , m is the mass of an object and g is acceleration of gravity .
Gravity on Earth is 9.8 m/s² .
Jaden’s mass is 50 kilograms.
g = 9.8 m /s²
m = 50
Put the values in the formula
Thus
w = 50 × 9.8
= 490 kg m /s²
(As N = kg m/ s²)
= 490 N
Therefore the weight of the Jaden on earth is 490 N.
