My take (MCQ):

Question 1 (C)
Endocytosis

Question 2 (B)
Ribosomes

Question 3 (B)
RNA polymerase is attached to the promoter

Question 4 (D)
mRNA

Question 5 (A)
The activity of a protein may be affected by the temperature and pH of the environment

Question 6 (D)
Reduces acetylcholinesterase activity by reducing the number of active sites for acetylcholine to bind to

Question 7 (D)
If the temperature increases, then the bacteria will grow more quickly.

Question 8 (D)
The percentage of nutrient agar covered by bacteria

Question 9 (A)
Repeat the environment several times to find out if they would obtain the same data

Question 10 (D)
Phospholipids

Question 11 (A)
At any given time, the genes expressed in each cell may be different

Question 12 (B)
Fermentation in animals

Question 13 (B)
Oxygen concentration available to the mitochondria increases

Question 14 (A)
4 ATP produced and 2 ATP used for a net gain of 2ATP

Question 15 (C)
Light intensity is a limiting factor when the photosynthesis rate is less than 40 arbitrary units

Question 16 (D)
In the cytosol

Question 17 (C)
Neutrotransmitters: producers a rapid response; hormones: can target many cells or organs at once, but are not the most rapid; pheromones: can affect another organism at a distance; cytokines: targets nearby cells during inflammation

Question 18 (B)
A decrease in apoptosis, resulting in increased survival of pre-cancer cells

Question 19 (D)
T cytotoxic cells

Question 20 (A)
Enzymes that break down the microorganism are released into the vesicle

Question 25 (D)
T.flavidus and T. lineatus diverged to form two distinct species 25 million years ago

Question 26 (C)
The frequency of each allele is equal in Generation 1 but not in other generations

Selective breeding

Question 28 (C)
A trace fossil

Question 34 (B)
Stops cell wall synthesis in bacteria

Question 35 (B)
Simple bacterial infections may become life-threatening for patients

Question 36 (A)
Transgenic organism

Question 37 (C)
Negative impacts on ecosystems could be reduced

Question 38 (A)
Joins two DNA fragments together by forming phosphodiester bonds between the two fragments

Question 39 (C)
Number of restriction sites cut: 4; number of DNA fragments produced: 4

Question 40 (A)
The presence of an opposable thumb

On the last Mcq Iím pretty sure it was that they lack a tail, because old world monkeys have opposable thumbs and they are not homonoids. Also I checked my connect book and it said a lack of tail.

they r absolutely right. Its the absence of a tail.

Also question 24. the answer was P. chilotes. Very high majority answered that (including teachers)
