How is an HIV infection different from a cold virus infection?
A. HIV is killed by macrophages.
B. HIV is a bacteria.
C. HIV is a lipase.
D. HIV attacks helper T cells.
Answer:
HIV attacks helper T cells.
Explanation:
The correct answer is that HIV attacks helper T cells, while a cold virus infection does not. That is in Option D, as an HIV (human immunodeficiency virus) infection and a cold virus infection are caused by two different types of viruses.
What is HIV?HIV is a retrovirus, which means that it contains RNA as its genetic material instead of DNA. When the virus infects a host cell, it uses an enzyme called reverse transcriptase to convert its RNA into DNA, which is then integrated into the host cell's genome. This allows the virus to hijack the host cell's machinery and produce more copies of itself, which can then infect other cells in the body. One of the main targets of HIV infection is the CD4+ T cell, also known as the helper T cell. Helper T cells play a key role in the immune system by helping to activate and coordinate other immune cells, such as B cells and cytotoxic T cells.
Hence, the correct answer is that HIV attacks helper T cells, while a cold virus infection does not. That is in Option D.

Why are the components of the electron transport chain embedded in the inner mitochondrial membrane rather than floating freely in the cytoplasm of mitochondrial matrix?.
Answer:
To generate and maintain the proton gradient essential for ATP production.
Explanation:
ATP is also formed from the process of cellular respiration in the mitochondria of a cell. This can be through aerobic respiration, which requires oxygen, or anaerobic respiration, which does not. Aerobic respiration produces ATP (along with carbon dioxide and water) from glucose and oxygen.
Give an example of a protein for each of the functions of proteins.

choose a plant or animal that you think is interesting. describe some of the threats or challenges
Answer:
If I were to choose a plant or animal which is interesting, I'd choose the "cactus."
Explanation:
A "cactus" is truly a splendid plant owing to its ability to survive in the desert or periods of drought. Growing them is also not that challenging or difficult. However, this plant is prone to certain threats that may lead to its extinction.
One of these threats is the "over-collection of cacti." Due to its versatile use, the cactus is often sold as an ornamental plant. Another threat is the number of pests, such as snails and slugs, that attacks it yearly. It is a delicious food for mealy bugs, red spider mites, gnats, flies, etc.People often misunderstand the cactus' water level needs. Some people over-water the plant and this often results to the bacteria, virus and fungi being attracted to it.Water Hyacinth
Water Hyacinth grows profusely, forming dense mats that can spread across water surfaces eventually blocking the entire water body.
It can eliminate native wetlands and waterways and kill aboriginal fish and other wildlife.
Also, it causes a high evaporation rate and loss of water and degrades water quality.
What are the natural predators of the water hyacinth?
Water hyacinth is native to South America, the only continent where natural predators such as weevils and moths keep it at bay.
Thus, these are some of the threats or challenges of water hyacinth.

Explanation:
How is the idea of PTT related to the
locations and distribution of volcanoes,
earthquake epicenters and mountain ranges?
Answer and Explanation:
The mantle is one of the four layers that form the earth. It is a very hot and dense rock, that is capable of flow. The crust is the outermost layer of the earth and is located just over the mantle. The crust is divided into many plates, that are able to move over the mantle.
The tectonic plates theory, PTT, is based on the continual movements of the crust and might explain the movement of the different plates, and their directions and interactions.
Plates are limited by three different ridges or borders that differ in the type of movement they produce.
Divergent limits: where two plates get separated, leaving a space among them that make a place for a stream of hot material that comes from the mantle to create a new seabed. This separation occurs because of the sea bottom expansion. As old plates get separated, the new and young crust instantaneously gets formed. There is never an open space left, because the emerging mantle occupies that place. This process occurs along with an underwater mountain range which is known as the mid-oceanic ridge or divergent ridge. An example of this is the ridge located in the middle of the Atlantic Ocean, extending from Greenlander to the southernmost point of South America. These divergent limits are in general associated with the rocky material involved in the expansion of the seafloor.
Convergent limits: These movements occur when two plates collide. It might occur among two oceanic plates or one oceanic and one continental plate. In this last case, the oceanic plate is always the one that subducts. The thicker and older plate subduces under the other plate, and at this point, it starts the volcanic activity. As the thicker plate descends, it is heated and melted and its materials are incorporated into the mantle. As the older plate subducts, all the sedimental material that was on the surface of this plate, accumulate and incorporate into a wedge-shaped mass known as an accretion prism. The fast subduction and accretion prism formation make a place for magma that ascends to the surface by crevices. This produces the formation of the volcanic arches, located behind the accretion prism. If these arches are formed on the continental plate, these formations are known as continental arches. But if they occur in another oceanic plate, the arches are known as volcanic island arches. The volcanic islands are arranged in a circumference arch shape, which is bordered by a fossa. Subduction zones coincide with deep-sea trenches or depressions in the ocean bed. The Mariana Islands in the Pacific Ocean are examples of these volcanic islands. The Nazca plate is another example oceanic plate subducting under the south American plate and originating the Andes mountains.
Transforming limits refer to geological structures related to the seafloor expansion and associated in general with the oceanic ridge, although they might also occur in the continental plate. These limits are known as geological faults, where no rocky material is either destroyed or formed. When the plates move and one of the transforming limits displace from side to side, earthquakes occur. The movement breaks the crust and originates pronounced fractures. The San Andrés fault is an example of this plate ridges.

Answer:

Explanation:
A.) is correct because the anticodon is what connects the tRNA to the mRNA. To form a bond between these sequences, they must be complementary.
B.) is incorrect because it describes the other end of the tRNA molecule.
C.) is incorrect because it is complementary to the mRNA strand, not rRNA.
D.) is incorrect because the anticodon does not change its sequence.
