One of the major elements of natural selection is that all species have genetic variation. Natural selection is a process when organisms adapt better to their environment. It is an essential key in evolution. There is a change in phenotype of a population over time.

If two objects are compared at a certain distance, according to Newton’s law of universal gravitation, what is true? Complete th
Xelga [282]

1. Both objects have mass and therefore have  a gravitational force.

2. Lower mass objects have  less gravitational force.

3. Higher mass objects have  stronger gravitational force.

Explanation:

To solve this problem, we need a recap of the newton's law of universal gravitation:

The law states that "the gravitational force of attraction between two object is directly proportional to the product of their masses and inversely proportional to the square of the distances between them."

   F = \frac{G[tex]m_{1} m_{2}}{r^{2}}[/tex]

 G = universal gravitational constant

 m₁ = mass of object 1

 m₂ = mass of object 2

  r² = distances between the two masses

From this we can infer that, for gravitational force to exists, both objects must have mass.

Since mass is directly proportional the gravitational force, the lower the mass the less the gravitational force and the higher the mass the stronger the gravitational force.

Genetic material includes two basic molecules. What are they? <br> A) ADP and ATP<br> B) RNA and DNA
bixtya [17]

DNA is the genetic material, in a double helix shape, used to make proteins. RNA is the single helix molecule that actually turnd DNA instructions into proteins. ATP is the main storage unit of chemical energy in the cell. All this is a basic comparison you should have learned in 9th grade Biology.

Hope I helped!!!!

In the small intestine, where are fatty acids and monoglycerides absorbed?
Inessa [10]

Answer:B

Explanation:when fat are ingested,it has to be emulsified and broken down into monoglycerides,fatty acids.these molecules have a polar hydrophilic end and a non polar hydrophobic end .the fatty acid and monoglycerides that enter the cells of the mucosa are formed back into large tryglycerides molecules ,which then forms chylomicros, which are water soluble.they then pass into the lacteal vessels from where there are Transported to meet the body's needs

A nurse assisting a nursing student with medications asks the student to describe how penicillins (PCNs) work to treat bacterial
Mnenie [13.5K]

Penicillins disrupts bacterial cell wall synthesis.

<h3>How does penicillin affect bacterial cell walls?</h3>
  • Penicillin kills bacteria by inhibiting the proteins which cross-link peptidoglycans in the cell wall .
  • When a bacterium divides in the presence of penicillin, it cannot fill in the “holes” left in its cell wall.
  • β-Lactam antibiotics, including penicillins, cephalosporins, monobactams, and carbapenems, are distinguished by a lactam ring in their molecular structure and act by inhibiting the synthesis of the peptidoglycan layer of bacterial cell walls.
  • Penicillins work by bursting the cell wall of bacteria. Drugs in the penicillin class work by indirectly bursting bacterial cell walls.
  • They do this by acting directly on peptidoglycans, which play an essential structural role in bacterial cells.
