They show how all creatures have adapted such as giant dinosaurs are now tiny lizards =D<span />
The mass (in grams) of NaCl required to prepare the solution is 36.27 g
<h3>What is molarity?</h3>
Molarity is defined as the mole of solute per unit litre of solution. Mathematically, it can be expressed as:
Molarity = mole / Volume
<h3>How to determine the mole of NaCl</h3>
- Volume = 200 mL = 200 / 1000 = 0.2 L
- Molarity = 3.1 M
- Mole of NaCl =?
The mole of NaCl in the solution can be obtained as follow:
Molarity = mole / Volume
Cross multiply
Mole = Molarity x Volume
Mole of NaCl = 3.1 × 0.2
Mole of NaCl = 0.62 mole
<h3>How to determine the mass of NaCl </h3>
We can obtain the mass of NaCl needed to prepare the solution as follow:
- Molar mass of NaCl = 58.5 g/mol
- Mole of NaCl = 0.62 mole
- Mass of NaCl = ?
Mole = mass / molar mass
Cross multiply
Mass = mole × molar mass
Mass of NaCl = 0.62 × 58.5
Mass of NaCl = 36.27 g

Answer:
A variation is different to an adaptation as a variation is a difference or variety inside a species, for example a different breed of dog such as a spaniel is a variety of the dog species, whereas an adaptation is a genetic mutation that has developed in order to help an animal survive, such as giraffes having a long neck. Adaptations continue throughout the species due to natural selection.
Answer:
The ratios of thymine and adenine were similar, as were the ratios of guanine and cytosine.
Explanation:
deoxyribose + phosphate group + thymine
Answer:
The correct answer is option B, that is, cerebral palsy.
Explanation:
An array of disorders, which influence the tendency of an individual to move and maintain posture and balance is termed as cerebral palsy. The condition is most commonly witnessed in childhood and is a motor disability associated with the poor functioning of the brain. The condition results in muscle weakness as part of the brain that helps in controlling muscles get affected.
The signs and symptoms of cerebral palsy vary, for example, individuals suffering from the extreme form of cerebral palsy would need the assistance of certain equipment in order to move. On the other hand, individual suffering from mild cerebral palsy can walk to a certain extent, however, might also need help in order to do that.
Cerebral palsy can result in many conditions based on the part of the brain getting affected like stiff muscles, poor balance and coordination, and uncontrollable movements. Thus, in the given case, Sammy is suffering from cerebral palsy.
