cientists think that the position of the nostrils gives modern whales an evolutionary advantage. Which of the following most likely describes how this adaptation is advantageous?
O The nostril position allows whales to obtain air more easily at the surface of the water.
The nostril position allows whales to obtain food more easily at the surface of the water.
O The space lett empty by the migrating nostrils has allowed modern whales to develop gills.
The space left empty by the migrating nostrils has allowed modern whales to develop teeth.

900J

Explanation:

Given parameters:

Specific heat of the aluminium = 900Jkg⁻¹K⁻¹

Mass of aluminium = 0.5kg

temperature change = 2K

Unknown:

Quantity of heat = ?

Solution:

The quantity of heat a body absorbs to cause a change in temperature is given as:

  H  = mcΘ

H is the quantity of heat

m is the mass of the substance

c is the specific heat capacity

Θ is the temperature change

 

   H = 0.5 x 2 x 900 = 900J

Bad White [126]

The bacteria, Angelinus ballerinea secretes a compound that inhibits the growth of other Gram-positive bacteria. Scientists take this compound and add chemical groups to it to make it more stable for use in humans to treat bacterial infections. This is an example of antibiotic.

<h3>What is antibiotic?</h3>
  • Antibiotics from the key class of glycopeptides can stop this process.
  • Through five H-bonds, these antibiotics bind to the C-terminal d-Ala-d-Ala of the murein precursor, lipid II, and immature peptidoglycan, preventing transglycosylation and/or transpeptidation during the production of the cell wall.
  • Contrarily, antibiotics have easier access to the thick, porous peptidoglycan layer in the cell walls of Gram-positive bacteria, allowing them to more easily enter the cell and/or interact with the peptidoglycan itself.
  • The two main antibiotics that prevent the synthesis of bacterial cell walls are penicillins and cephalosporins.
  • Penicillin is one of many antibiotics that assault the bacterial cell wall in order to operate.
  • The medications specifically stop the bacteria from producing peptidoglycan, a chemical that gives the cell wall the toughness it needs to live in the human body.
