Answer:

if your brain is distracted, then you'll have a slower reaction time. if not, then you have a faster reaction time.

Other things can depend. If the object is to fast or to slow, that could also delay reaction times.

Answer:

The Markonikov's rule determines where to add a nucleotide in the reaction

Explanation:

In organic chemistry, the organic carbonyl reactions are governed by a set of rules. One of them is the Markovnikov's rule. Basically, the rule determines where the addition of the nucleophile and a hydrogen will take place in a chemical reaction involving alkene addition. In the reaction principles, there are rules to follow based on the syn and anti addition. This refers to which side the two groups will face. they add to the same side an called the syn. When its opposite side, then its anti.

1. Suppose that you take your boat offshore for a day of deep-sea fishing. You drop anchor at a supposed ‘hot spot’ and you noti
Mashcka [7]

The swim bladder is more or less an oval, soft-walled pouch located in the abdominal cavity, just below the spinal column. Its shape varies greatly, but the volume is constant between species, most often around 5% of body.

<h3>Day of deep-sea fishing</h3>

1. The volume of your swim bladder when you put it back in the water would be 7.5 liters.

2. The time the fish would float on the surface before the oval could restore neutral buoyancy would be a few seconds.

3. If I were a red blood cell that has just delivered its oxygen to the tail musculature of a mako shark, the route through the circulatory system to eventually reach the mako's swim bladder would be the venous route, like other fish, they have a heart with two chambers, an atrium and a ventricle, and closed circulation.

With this information, we can conclude that the volume of her swim bladder when she was put back in the water would be 7.5 liters.

What are some advantages and disadvantages of long femur lengths (crickets)?​
MrRa [10]

Answer and Explanation:

In crickets, femur length represents a highly important trait associated with jumping performance - an essential behavior for their survival and reproduction.

According to research, these are the possible advantages and disadvantages in regard to long femur length:

Advantages

  • Longer legs [may] provide higher power for the muscles in order to jump.
  • Long-legged crickets generate lower reaction forces while performing a jump, which enables them to lose less energy in comparison with crickets with shorter femur length.

Disadvantages

  • Longer femurs may increase the total take-off time of a cricken prior to a jump.
  • In some cases, longer femurs force insects to develop head or body structures to enable them to 'fit' the legs while they prepare to jump.
  • Increased energy loss while jumping from an elevated leaf.
