Answer:

The conservationists effectively identified a problem, specifically that young penguins were underweight. They fed the young birds, increasing the probability that they would reach reproductive age. The program also ensured that the young penguins could survive in the wild, by teaching them survival skills. A limitation of this program is that after the birds return to the wild, they face the same problems of high competition and limited food supply. Although the program increases their chances for reproduction, it doesn’t guarantee that they’ll be successful.

My name is Ann [436]

The best answer is B (semi permeable)
The cell membrane of a red blood cell is semi permeable membrane. This is a type of biological membrane that will allow certain molecules or ions to pass through while barring others.

Red blood cells have very thin membranes that allow oxygen diffuse through quickly. They are also permeable to water and osmosis across the membrane occurs very rapidly. In the body, they are bathed  in isotonic plasma in which case water movement  into the cell is equal to water movement out of the cell and so the cells remain intact.

If adenine didn’t always pair with thymine and guanine didn’t always pair with cytosine, the new DNA ladders wouldn’t always be
zloy xaker [14]

Answer:

they wouldnt be identical because for example Guanine could be paired with thymine in the original DNA strand but could decide to pair with adenine in the replication DNA. that would make a different type of DNA.

Explanation:

DNA replication is a beautiful process. In DNA replication adenine only pairs with thymine and guanine only pairs with cytosine. this ensures that a replication of the DNA will be the same type of DNA.

Replication works like this. Helicase splits open the DNA and each side is copied by DNA polymerase. If let's say the nucleotide bases for side 1 are ATGCGA then the DNA polymerase will pair these with the matching bases TACGCT which will make the same DNA but if each base could pair with any base they want that could create a few different variations of the original DNA. ATGCGA could very well be paired with TCGACA or CGACTA which would created two different types of DNA.

The lac operon in E.coli regulates genes that code for enzymes required for breakdown of lactose. The lac operon is____ operon t
user100 [1]

Ans.

Lac (lactose) operon in a type of bacterial operon, which shows a cluster of genes that are regulated by a single promoter. It is composed of an operator, promoter, a terminator, and three structural genes (lacA, lacY, and lacZ), which are responsible for the transport and breakdown of lactose.

The lac operon is an inducible operon as it gets activated in the presence of lactose and expressed its functional genes in the form of proteins (or enzymes) for lactose metabolism.  

Thus, the correct answer to be fill in first blank is 'inducible' and in second blank is 'lactose.'
