Stells [14]2 years ago
8 0

Answer:

<em><u>As the instructor, you supply the carbon source by blowing bubbles in phenol red. The carbon dioxide in your breath will dissolve in water to form carbonic acid, which lowers the pH of the solution. Phenol red turns yellow in a pH lower than 7, revealing in this case the presence of a carbon source.</u></em>

melamori03 [73]

Answer:

1. Supplying

2. Taking

Explanation:

Food chain is a linear relationship between organisms that depicts the flow of energy from one organism to another. In a food chain, organisms are arranged in trophic levels where arrows pointing to the right direction (➡) are used to show that the organim the arrow is pointing to eats the organism behind it.

Hence, according to this question, arrows in a food chain point from the organism SUPPLYING the energy to the organism TAKING the energy.

Which best describes the offspring of protists?
Hunter-Best [27]

Options found elsewhere:

-always genetically identical to one parent

-always genetically identical to both parents

-never genetically identical to one parent

-sometimes genetically different than both parents

Answer:

-sometimes genetically different than both parents

Explanation:

Protists are eukaryotes that cannot be classed as animals, plants, or fungi. They are quite diverse. Examples include amoeba, plasmodium, and slime mould.

Because they are so diverse, protists also have very different modes of reproduction. Some protists undergo asexual reproduction, where they simply make a copy of themselves without a mate. Others undergo sexual reproduction.

Therefore, the only option that can be correct is "-sometimes genetically different than both parents" .

If they were always genetically identical to one parent or both parents, that would mean that sexual reproduction could not be possible. If they were never genetically identical to one parent, that would mean that asexual reproduction could not be taking place.

Sladkaya [172]

Answer:a. Draw Punnett squares for each couple (you may need to do more than 1 square/ couple)

Baby 2 MUST belong to the Browns because Mr. Brown is the only parent with an A allele to

contribute… then the rest works out as follows:

b. To which parents does baby #1 belong? Why? Hint you may want to refer to your Punnett

squares.

Baby 1 must belong to the Smiths, because they are the only ones with the possibility of EACH

having a recessive allele to pass down to the baby, Mr. Brown has type AB blood and therefore

only has the dominant A and dominant B alleles – no recessive allele possible.
