An ultrasound can produce the image of a fetus by using waves that are labeled as "ultrasound waves" or in ultrasonic frequency.
This may seem like an odd concept but you should note that everything we see and hear is made up of waves, like light and sound, that are at different frequencies.
The reason why there are different color lights are because there are different type of frequencies. Some frequencies, such as ultrasonic, we can not see with our human eye.<span />
Answer:
Carbohydrates are foods that get converted into glucose, or sugar, in our bodies during digestion. Glucose is a main source of fuel for our body.
Explanation:
Answer:
One advantage of models is that all the mice are exactly alike except for color, enabling the control of all variables except the one being studied. Models are also easier to work with than live mice. One disadvantage of using models is that they do not have the same smell and behaviors as real mice.
Another advantage is that models can be reused for the experiment for a longer period of time with less maintenance.
Answer:
It requires energy
Explanation:
In the coupled transport system, coupled carriers couple the inward transport of one solute across the membrane to the outward transport of other solutes across the membrane. The tight bonding that occurs between the transport of two solutes allows these carriers to utilize the energy stored in one solute, usually an ion, to facilitate transport of the other. With this way, the free energy released during the movement of an ion down an electrochemical gradient is utilized as the driving force to transport other solutes inwards, against their electrochemical gradient.
Answer options:
- fruit
- pollen
- flower
- seed
- spore
Answer:
flower
fruit
Explanation:
Angiosperms include all flowering plants. Therefore, all plants in this group have flowers, whereas other groups do not.
Both angiosperms and gymnosperms have seeds, but angiosperms are defined by the fact that their seeds develop within a surrounding layer of usually the flower. Both angiosperms and gymnosperms also have pollen - likely an adaptation to living on dry land. Many plants produce spores, not just angiosperms.
Angiosperms produce fruit, unlike other plant groups. This fruit is the protective layer that encases their seeds, unlike gymnosperms, where the seeds are 'naked'
