Answer:
<h3>Seafloor sediment consist mostly of terrigenous sediment, biogenous sediment and hydrogenous sediment. Terrigenous sediments form from sediments carried from the land into the ocean by water, wind or ice.</h3>
To start, move the objective lens to its lowest power setting. Place a slide on the stage with the label side up and the cover slip in the middle. You can only use the coarse focus knob when the power is low. If you can't see anything, move the slide a little while you look and focus. If nothing shows up, turn down the light and move the slide a little while you're looking and focusing. Once you're in focus on low power, move the slide to make the object of interest in the middle of it. Turn the objective to medium power and only change the fine focus. If you need to, turn the objective to high power and only adjust the fine focus.
Answer:
C)
Explanation:
Meiosis creates sex cells (gametes) for sexual reproduction. And the resulting daughter cells have have the number of chromosomes as the parent cell.
The following given statements are true of trans-fatty acids:
A. Often created by treating plant oils with hydrogen
D. Occur naturally in in food
<u>Explanation:</u>
The unsaturated fatty acids that are produced by a method called hydrogenation through the addition of a hydrogen molecule to vegetable oils is understood as "Trans-fatty acids". According to the hydrogenation process the composition of the fatty acids varies. The unsaturated fatty acids trans structure receives one double conjugated bond and obtains a straight shape and rectifies the twisted shape created by cis bonds.
Increasing the concentrations of trans-fatty acids particularly in the red blood cell membranes can lead to blockage of the blood vessel as a whole and enhance the risk of heart disease. Meat and dairy products kind natural food materials include trans fatty acids.
Answer:
The correct answer is: C.
Explanation:
- The given situation is the example of a Reflex Action.
- Reflex action can be defined as an action shown in response to a sudden stimulus.
- The CNS or the Central Nervous System is comprised of the Brain and the Spinal Cord which receives the Sensory impulses from the Receptor organ, integrates or decides on the response which needs to be provided and then sends the Response impulses to the Effector organ.
- The PNS or the Peripheral Nervous System is comprised of the sensory and motor neurons those are responsible for connecting the Sensory organ and the Motor organ to the CNS, respectively.
- In the situation, Sarah's eyes perceives the ball and sends sensory impulses through the optic nerve containing the sensory neurons (PNS) to the spinal cord.
- The spinal cord possess inter-neurons (CNS) that decides over the action to be done in response to the stimulus.
- The Response stimulus is send from the inter-neurons via the motor neurons (PNS) to the eye muscles of Sarah and Sarah performs the action, that is, she blinks.
