16. Which organelle may have allowed early eukaryotes to make food and produce oxygen? (a) the Golgi apparatus (b) the central vacuole (c) the plastids
Answer:
the plastids
Explanation:
Answer:
The plastids are the organelles that compose the cells of plants and algae. These contain chloroplasts, which allow them to capture energy from sunlight. If they are ever removed, these cells will eventually lose their ability to photosynthesize food without help from another organism - they have lost an essential organelle. Without the presence of this organelle, eukaryotes may not have been able to use sunlight as a mechanism for producing oxygen or making nutrients such as glucose available for consumption.
The organelle that may have allowed early eukaryotes to make food and produce oxygen is the plastid. The correct option is c.
What is plastid?The organelles that make up the cells of plants and algae are called plastids. These have chloroplasts, which enable them to absorb solar energy. These frequently include several kinds of pigments that can alter the color of the cell as well as pigments that are employed in photosynthesis.
These cells will eventually lose their capacity to photosynthesize food without the assistance of another creature if they are ever taken out since they have lost an important organelle.
Eukaryotes might not have been able to exploit sunlight to produce oxygen or make nutrients like glucose available for consumption without the presence of this organelle.
Therefore, the correct option is (c) the plastids.

visceral reflex arcs differ from somatic in that ________.
Explanation:
somatic reflex occurs in skeletal muscles whereas, the visceral reflex occurs in soft tissue organs.
The difference between visceral reflex arcs and somatic reflex arcs is that visceral turns require two motor neurons.
What are visceral reflex arcs?For instance, somatic reflexes require a direct link between the skeletal muscle and the ventral horn of the spinal cord. The central neuron of a visceral reflex sends a signal to a ganglion, which then sends another signal to the target effector.
While somatic reflexes are aware, visceral reflexes are unconscious. Compared to somatic reflexes, visceral reflexes entail a somewhat slower reaction time.
Visceral reflex arcs use two motor neurons along with glandular tissue and non-skeletal muscle to carry out a reflexive reaction. Skeletal muscles only have one motor neuron, therefore somatic reflex arcs include them.
Therefore, two motor neurons are involved in visceral arcs, which differ from somatic.

The upper epidermis of the leaf is transparent, allowing light to enter and they have a large surface area to volume ratio, allowing more light to enter.
What is responsible for photosynthesis to occur?The mesophyll cell is responsible for photosynthesis occurs. The majority of the chloroplasts and the primary site of photosynthesis are located in the palisade layer. The area of storage and gas exchange is the airy, spongy layer. The stomata control the water and carbon dioxide equilibrium.
For gaseous exchange and photosynthesis, leaves are suited. Since they have a wide surface area and stomata, which enable carbon dioxide to enter the leaf and oxygen to exit, they are well-equipped for photosynthesis.
Chloroplasts, which is known as the house the chlorophyll in plants, are where photosynthesis occurs. The thylakoid membrane, a third inner membrane that creates lengthy folds inside the chloroplast and is bordered by a double membrane, is present inside chloroplasts.

What evidence of climate change on continents supports the theory of continental drift?
signs that glaciers existed in South Africa
similar coal fields on different continents
change in atmospheric temperature over time
same animal fossils found on different continents
Answer:
A
Explanation:
Edge2022
The evidence of climate change on continents that supports the theory of continental drift is similar coal fields on different continents. Hence option B is correct.
What is continental drift theory?The theory of continental drift suggests that the Earth's continents were once joined together in a single landmass called Pangaea, which began to break apart around 200 million years ago.
This idea was first proposed by German scientist Alfred Wegener in the early 20th century, who noticed the striking similarities between the coastlines of Africa and South America.
Coal is formed from the remains of plants that lived millions of years ago, and its distribution can provide clues about how continents were once connected.
Coal fields found on different continents that match in age and composition indicate that the continents were once joined together in a larger landmass.
This supports the theory of continental drift, which states that the continents were once part of a single supercontinent that later broke apart and drifted into their present positions.
This evidence suggests that coal-forming swamps once existed in locations that are now separated by oceans and that these locations were once connected.
Hence option B similar coal fields on different continents is correct.

Mr. Allen wanted to fill balloons for a party. He rented a helium tank that contained 0.4 cubic meters of helium gas. He was concerned that the gas would not fill many balloons, but it filled 27 large balloons! Why was the small tank of helium gas able to fill so many balloons?
A. Helium mixed with air when it came out of the tank.
B. The helium expanded to fill its new containers, the balloons.
C. Helium molecules are very small in size.
D. The volume of gas in the balloons equaled the volume of gas in the tank.
Given what we know about the behavior of gases like helium, we can confirm that the small tank of helium was able to fill so many balloons because the helium expanded to fill its new container, which is the balloon.
Helium is a chemical element known as a noble gas. Like all other elements in a gaseous state, the atoms that comprise helium are spaced apart. This allows the gas to be compressed, a property that manufacturers of the gas take advantage of since they can compress a large amount of gas into a small container.
This is precisely what is happening in the question. The small tank of helium, despite being small in size, contains a large amount of compressed helium gas. Therefore, once it is released from the container, the gas expands to fill its new container, which in this case is the balloons, because of this, a relatively small tank of helium was able to fill many large balloons.
