Which statement below correctly explains and gives the importance of the endosymbiotic theory?
A. The endosymbiotic theory states that the inner and outer membrane of the endoplasmic reticulum indicates these were once free living organisms which were taken into an early cell via endocytosis. The theory was further supported by the presence of prokaryotic ribosomes and replication of the endoplasmic reticulum via binary fission.
B. The endosymbiotic theory states that the inner and outer membrane of the mitochondria indicates these were once free living organisms which were taken into an early cell via endocytosis. The theory was further supported by the presence of prokaryotic ribosomes and replication of mitochondria via binary fission.
C. The endosymbiotic theory states that through endocytosis, early prokaryotic cells were able to bring in additional nutrients. These additional nutrients provided important energy that drove evolution of these prokaryotic cells into the eukaryotic cells seen today in more advanced organisms.
D. The endosymbiotic theory states that through endocytosis, early prokaryotic cells were able to bring in early energy rich eukaryotic cells. The energy provided drove evolution of these prokaryotic cells into the eukaryotic cells seen today in more advanced organisms.

Answer:

True

Explanation:

Glucagon is a hormone that is involved in controlling blood sugar (glucose) levels. It is produced by the alpha cells, found in the islets of Langerhans, in the pancreas, from where it is released into the bloodstream.

Considering the structure and function of fats, an animal living near the poles would have more fat than an animal living near the equator. This is because fats provide insulation and store energy, which are crucial for survival in colder climates with seasonal food availability.

The structure and function of fats in an animal's body directly relate to the environment in which the animal lives. Fats serve primarily as energy storage and insulation. Considering this, an animal living close to the poles would need more fat compared to an animal living near the equator.

Animals in colder climates, like the poles, accumulate more fat for insulation to maintain their body temperature. The fat layer acts as a barrier, reducing heat loss and protecting them from freezing temperatures. Additionally, food resources in these regions could be scarce, especially in winter, so animals here need more fat reserves to supply energy when food is hard to find.

On the contrary, animals living near the equator, where climate is generally warmer and food is more abundantly available throughout the year, typically have less body fat as they require less insulation and energy storage.

Explanation:

Abrasion means scraping or wearing away. Thus option A is correct

Abrasion is easily recognized form of wear.

The hard particles can scratch softer surfaces when they are forced.

It can be  associated either with surface movement with packed particles  soil, sand, rocks or hard particles trapped between machine surfaces.

There are two types of abrasion such as low stress abrasion other wise known as two-body abrasion.

secondly high stress abrasion or three-body abrasion which is more severe because it can  increases the chances of fracture of the abrasive particles.

Quartz is a hard, crystalline second most abundant mineral available in earth's crust made up of silicon dioxide.

One of best classified quartz is called as gemstones and  antiquity a variety of quartz commonly used in jewelry and hardstone carvings. It is a substance which undergo abrasion for a long period.

Hence option A is correct.
