Answer:
B
Explanation:
This number that is put in a compound is called a subscript. It is put in front of the symbol of the element being represented. An example is CO₂ which means there are one (1) carbon and two (2) oxygen atoms in the compound.
A baker has created a new strain of yeast which contains no cytochrome c gene and no cytochrome c protein. this will affect what the yeast strain can do to obtain energy. what will this yeast strain do more of compared to a normal strain
Will this new strain of yeast obtain more or less free energy from glucose in its growing medium?
Answer: Less because cytochrome c is key to the electron transport chain.
Explanation:
The Cytochrome c is an essential component of the electron transport chain. Without this there will be no oxidation and reduction of iron atom will take place which could convert the ferrous ions to ferric ions. Thus the entire process of electron transport chain and energy production in the form of ATP will be compromised. So, there will be no production of energy in the anaerobic fermentation by yeast.
Answer:
Explanation:
From the question, the total population = 171 i.e (80+71+21)
Genetic frequency therefore; BB = 71/171 = 0.42
Bb = 80/171 = 0.47
bb = 20/171 = 0.12
Allele frequency therefore;
Allele B = 0.42+(0.50×0.47) = 0.66
Allele b = (0.50×0.47)+0.12 = 0.36
Note all values were rounded up to two significant figures
Evaporation I think what school level is this ?
Answer:
The hydrophobic core of the membrane does not allow the charged particles to pass through it.
Explanation:
The inner core of the membrane is made up of hydrophobic fatty acid tails of phospholipids. Due to this, some substances such as large, charged and polar particles cannot cross the membrane. This is why Na+ with a positive charge cross the membrane with the help of transport proteins only. On the other hand, molecular oxygen (O2) has a small structure and does not carry any charge. Therefore, it can cross the membrane without any help of transport proteins.
