You will feel the s-wave 12.4 seconds after you felt the p-wave.
<h3>
How to find the difference in time?</h3>
The waves must travel 250 km, we know that the p-wave travels with a velocity of 6.3km/s. The time it takes to travel that distance is given by:
250km/( 6.3km/s) = 39.68s
At this point is when you feel the p-wave.
The s-wave travels at 4.8 km/s, than it will take:
250km/(4.8km/s) = 52.08 s
The difference in time is:
d = 52.08s - 39.68s = 12.4 s
This means that you will feel the s-wave 12.4 seconds after you felt the p-wave.

When a butter is treated with fatty acid desaturase,
the hydrogen atom will be removed and form a carbon double bond, which allow the
membrane to become more fluid. When temperatures change, a phase transition
occurs. If the temperature decrease, the membrane gels becomes solid which then
results to cracks and the imbedded proteins cannot partake in conformational
changes, thus it is important to maintain membrane fluidity.

<h2>Answer:</h2>
Bt corn is a genetically modified organism that contains a gene of bacteria known as Bacillus thuringiensis.
<h3>Explanation:</h3>
- Bt corn is a type of transgenic crop that contains a gene which produces a crystal-like protein which has an insecticidal effect.
- This gene is present in bacteria. This gene is transferred to the plant by the recombinant DNA technology and genetic engineering.
- This bacterium is a soil bacterium which has no side effects on humans.
- Due to use of this technology, the poisonous chemical insecticides are not used in crop production.
Answer:
Fully enclosed in an ovary
Explanation:
A gymnosperm is a group of a plant which can be distinguished from other groups of a plant is through the presence of seeds but they are not enclosed and are naked.
The seeds are considered naked as they are not fully enclosed in the ovary like in the angiosperms rather they are present as on modified leaves called sporophylls and the cones.
The seeds are sheltered by the sporophyll and when they mature are enclosed by the sporophytic tissues. Since they are not enclosed in the ovary, therefore, are considered the gymnosperms.
Thus, the selected option is correct.
