The <em>correct</em> answer is:
Penicillium
Aspergillus
The lesson states:
If you've ever heard of or taken penicillin to fight off an infection, you can thank a member of the imperfect fungi called penicillium. Some mold species of penicillium are also important in the flavoring and aging of cheese. Roquefort and Camembert cheese owe their distinctive flavors to these fungi. Aspergillus is an imperfect fungus that is found on decaying food. It also contributes to the production of organic acids like citric acid. <u>Both penicillium and aspergillus produce enzymes that are purified and used in various industrial compounds and in medicine.</u>

Answer:
II and III
Explanation:
<em>I. All sons of these parents will be a hemophiliac.
</em>
<em>
II. A son who suffers from hemophilia received the hemophilia allele from his mother.
</em>
<em>
III. Half of the daughters of this cross are predicted to be hemophiliacs.</em>
Assuming the haemophilia allele is represented by h, the alternate form being H.
A woman that is a carrier will have the genotype 
.
A man who suffers from haemophilia will have the genotype 
Crossing both of them:
x = 
From the result of the cross, the following can be deduced:
- Half or 50% of the sons from the couple will be haemophiliacs.
- Any son that suffers from haemophilia received the allele from the mother.
- Half or 50% of the daughters from this cross will be hemophiliacs.
Hence, statements II and III are true.
When each cell specializes in a certain tasks, some cells make fingernails, others become blood cells, brain cells, kidney cells, Etc.
Answer:
Cane toads were introduced intentionally in Australia in 1935 to combat cane beetles in the sugar cane crop fields. These toads exhibit higher feeding capacity. These can feed not only cane beetles but other insects which affecting agricultural yields. They are poisonous in nature, they kill any insect after ingestion. Therefore, they are useful biological insecticide which provides crops resistance against insects.
All of the same atoms make up elements. It's the arrangement of these atoms that really matters. Your answer is true, an atom that makes up gold will indeed be the same atom that makes up silver.
Atoms are just mostly empty space, in fact about 99.99 infinitely percent of an atom is just empty space. We don't actually touch anything, not really. You never make solid contact with an object, but in fact what you're touching is that objects electrostatic field, or otherwise known as it's electron shell. You don't simply pass through an object because like charges repel eachother, the shell and your atoms, which creates the illusion that you're actually touching the object, when in fact your just touching it's invisible electrostatic shell.
If an atom gains an electron, it will have a NEGATIVE charge. Protons are positive charges, neutrons are neutral charges, electrons are negative charges. Add an electron that out-weighs the net-charge, which is 0, then you'll have an anion, or a negative charge.
The nucleus of an atom is indeed the center of an atom, the most dense area. This carries all of the weight (practically). The nucleus is indeed made up of positive and neutral charges, with an outer shell of negative charges. This is true.
