Describe the difference between the Rough Endoplasmic Reticulum and the Smooth Endoplasmic Reticulum. Be sure to include structure and function.
Answers
The main difference between the Rough Endoplasmatic Reticulum (RER) and the Smooth Endoplasmatic Reticulum (SER) is that the RER has attached to its surface ribosomes. This changes its appearence.
The RER and SER also differ in their function. Whereas the SER is involved in the synthesis and storage of lipids that are used in the generation of the cell membrane (includes cholesterol and phospholipids), the RER participates in the synthesis of enzymes and proteins.

What is a food web?We know that the food web is a representation of all the feeding relationships that are possible in the ecosystem. We know that in the ecosystem there are several feeding levels that run from the primary level way up to the secondary level.
In the primary level we have the primary producers which in this case are the green plants. Then we have the primary consumers which are the herbivores. From there we have the secondary consumers who feed on the herbivores and subsequently the secondary and the tertiary consumers.
The apex of the food chain is made up of the consumers that are found in the ecosystem.

How would a red blood cell behave in water?Red blood cells absorb water by osmosis if they are submerged in water. Because of the membrane's fragility, a cell will rupture as its volume and consequent pressure rise. When red blood cells are exposed to intense sugar solutions, water osmosis causes them to shrink.
There is a net transfer of water from the solution into the body in hypotonic solutions. When a cell is put in a hypotonic solution, cytolysis causes the cell to inflate and grow until it ultimately bursts.

Answers
The sensory portion of the PNS carries electrical signals towards the CNS; the motor portion carries electrical signals away from the CNS.
The peripheral nervous system( PNS) provides 2- way communication between the CNS( brain and spinal cord) and the rest of the body. It consists of 12 couplets of cranial nerves, pairs of spinal roots and spinal nerves, autonomic nerve caddies with associated ganglia, nerve plexuses, and nerves.
The somatic system is the part of the peripheral nervous system responsible for carrying sensory and motor data to and from the central nervous system. Afferent neurons convey information from sensory receptors of the skin and distinct organs to the central nervous system( i.e., brain and spinal cord), whereas efferent neurons carry motor information down from the central nervous system to the muscles and glands of the body.

The theory of endosymbiosis proposes that eukaryotes descended from a primitive combination of both archaea and bacteria. What evidence supports this theory?
Answers
The theory of endosymbiosis proposes that eukaryotes descended from a combination of both archaea and bacteria. Evidence that supports this theory includes the similarities between mitochondria and chloroplasts to free-living bacteria, the presence of double membranes around mitochondria and chloroplasts, and the fact that mitochondria and chloroplasts have their own DNA.
Explanation:
The theory of endosymbiosis proposes that eukaryotes descended from a combination of both archaea and bacteria. Evidence that supports this theory includes the similarities between mitochondria and chloroplasts to free-living bacteria, the presence of double membranes around mitochondria and chloroplasts, and the fact that mitochondria and chloroplasts have their own DNA.
Mitochondria and chloroplasts contain some of the same enzymes and transport systems as bacteria, and are similar in size and shape to bacteria. In addition, they both reproduce by binary fission, similar to bacteria. The presence of double membranes around mitochondria and chloroplasts also supports the theory of endosymbiosis, as this suggests that the organelles were engulfed by the host cell and retained their own membranes.
Finally, mitochondria and chloroplasts have their own DNA, which is circular like bacterial DNA. The DNA of mitochondria and chloroplasts also lacks histones, which are present in eukaryotic DNA, and is more similar to bacterial DNA in terms of gene expression and replication.
Together, these lines of evidence support the theory of endosymbiosis and suggest that mitochondria and chloroplasts were once free-living bacteria that were engulfed by a host cell and evolved into the organelles found in eukaryotic cells today.

Asexually reproducing animal populations are rare, but they typically consist of females who produce female offspring, so all offspring can produce more offspring. By contrast, half of the offspring of the sexual reproducers are male and cannot produce offspring. Thus, a clonal population of females can expand much more quickly than a population of sexual reproducers.
Potamopyrgus antipodarum is a species of freshwater snail that has spread far beyond its native New Zealand. Some populations of these tiny snails reproduce sexually, and other populations reproduce asexually. Huge asexual populations are now disrupting ecosystems all over the world, particularly where the water is contaminated with phosphorus. Fertilizers and detergents contain phosphorus, so agricultural runoff and other forms of water pollution are common in these regions. Like most animals that cannot reproduce sexually, the asexual snails have at least three sets of chromosomes; like most sexual organisms, the sexual snails have two. Explain why sexually reproducing snail populations predominate in regions where the water is unpolluted.

Which of the following does not yield wool ? (a) yak (b) camel (c) goat (d) woolly dog
Answers
Explanation:Why is option A (yak) not correct?
The Himalayan region is home to the yak, a type of cattle. They have a reputation for having long, shaggy hair, which is used to create many different textiles, including wool. Yak wool is popular because it is soft, warm, and long-lasting and is frequently used to manufacture clothes and blankets.
Why is option B (camel) not correct?Camels are widely known for their capacity to survive in difficult desert situations, and their wool is a valuable resource in many parts of the world. Clothing, rugs, and other textiles are frequently made from camel wool because it is cosy and soft.
Why is option C (goat) not correct?Goats are another typical source of wool, especially in warmer locations where other types of wool are less common. Depending on the breed of goat and the quality of the wool, the term "mohair" or "cashmere" is frequently used to describe the wool from goats. Cashmere is appreciated for its warmth and luxurious feel, while mohair is renowned for its softness, sheen, and insulating qualities.
Why is Option D (woolly dog) correct?Despite the fact that there are numerous dog breeds with long, shaggy hair, none of them actually produce true wool. Dog hair is not often used to produce textiles since it is formed of a different kind of fibre than wool. Although some dog hair can be spun into yarn and used for crafts, it is not regarded as a true wool and is not widely utilised for the manufacturing of textiles.

How rapid changes in weather conditions occur. Arrow labeled Direction of frontal movement points right toward Cold front map symbol. Arrow labeled Rising warm air in front of cold front points from cold front to sky. Also labeled are: Development of clouds because of upward movement of warm air, and Advancing cold air behind cold front.
Based on the arrows, what does the image represent?
Air masses are barely moving.
Air masses are colliding with each other.
Jet streams are forming in the upper atmosphere.
Weather conditions are remaining steady and unchanged.
Answers
The image represents air masses colliding with each other, leading to rapid changes in weather conditions.
The image represents the process of rapid changes in weather conditions occurring. The arrows in the image indicate various elements and phenomena related to these changes.
At the top, the final answer is that the image represents "Air masses are colliding with each other."
1. The arrow labeled "Direction of frontal movement" points right toward the "Cold front" map symbol. This indicates the movement of a cold front.
2. The arrow labeled "Rising warm air in front of cold front" points from the cold front upward into the sky. This signifies the upward movement of warm air.
3. The image also shows the development of clouds due to the upward movement of warm air. This indicates the presence of moisture in the atmosphere.
4. Finally, the image depicts advancing cold air behind the cold front, indicated by an arrow. This cold air is moving in the direction of the warm air.
Putting all these elements together, we can conclude that the image represents air masses colliding with each other. The cold front is advancing and pushing against the warm air, leading to the formation of clouds and changes in weather conditions. This collision between air masses often results in rapid changes in weather patterns, such as storms, rain, or temperature fluctuations.
