Archaea are in a different domain from bacteria because they both are evolved from eukaryotes. Thus, the correct option is A.
What are Archaea and bacteria?Archaea is an independent domain of single-celled organisms. These microorganisms generally lack a cell nuclei and are therefore prokaryotic organism. Archaea are the organisms which were initially classified as bacteria.
Bacteria are ubiquitous, mostly free-living organisms which are often consisting of only one biological cell. Bacteria constitute a large domain of prokaryotic microorganisms. They are typically a few micrometers in length, bacterial species were among the first life forms to appear on this Earth, and are present in most of its habitats.
Therefore, the correct option is A.

Consider this animal cell. The organelles in an animal cell are labeled. Part A is a structure with stacked membranes, part E represents small dots on the nucleolus, part F is a network of hollow tubes, flattened sheets, and round sacs, and part G is a bean-shaped structure with folding inside. Which organelle is responsible for producing the energy for cellular processes? organelle A organelle E organelle F organelle G
Answer:
G is a bean-shaped structure with folding inside
Explanation:
The Bean shape structure is the shape of Mitochondria, therefore it is the organelle of cellular respiration.
Kreb's Cycle and oxiadative phosphorylation are the major stages of of Cellular respiration which takes place in the mitochondria.
Cellular respiration is the process of extracting the energy as ATPs contained in foods(glucose, fatty acids, Aa) by combining them with oxygen.
Electron transport chains generate the energy for pumping protons to generate the energy, for ATPs synthesis, by enzyme ATPase synthases.

Scientists have been studying threats to coral reefs. The percent of reefs affected by various threats are shown in the figure below. A future global temperature increase may affect all categories on the figure. Predict which category would change the most from global temperature increases and propose a testable question that scientists could study.
a. The biggest effect will be on the far right column that includes thermal stress with a greater percentage of reefs falling into the low and medium threat categories. Scientists could test whether reefs that have greater fishing risk also have greater thermal risk.
b. The biggest effect will be on the far right column that includes thermal stress, with a greater percentage of reefs falling into the high and very high threat categories. Scientists could test whether reefs that have greater temperature changes have greater increases in watershed-based pollution.
c. The biggest effect will be on the far left column that includes fishing, with a greater percentage of reefs falling into the high and very high threat categories. Scientists could test whether increased fishing causes increased marine-based pollution.
d. The biggest effect will be on the far left column that includes fishing, with a greater percentage of reefs falling into the low and medium threat categories. Scientists could test whether reefs that have greater temperature changes have greater increases in fishing threats.
Answer:
It's B
Explanation:
Temperature rise will eventually end up putting coral reefs into the high threat categories, not fishing and DEFFINITELY not lowering their "risk" factor.
Coral reefs are the organisms of the aquatic ecosystem. The column includes the thermal stress that will be affected the most as the reefs fall into high and very high threats are huge. Thus, option B is correct.
What is the effect of thermal stress on coral reefs?Due to an increase in pollution and global warming, the oceans have heated up, which results in thermal stress and leads to coral bleaching and threat to the coral reefs.
The percentage of the very highly threatened, highly threatened, slightly threatened, and threatened reefs are seen majorly due to the thermal stress. Thermal stress is in increases amount due to oceanic warm-ups.
The thermal stress due to increased carbon dioxide activities and acidity leads to coral bleaching causes the destruction of the reefs and their endangerment.
Therefore, option B. the far right column labeled thermal stress has the biggest effect on the coral reefs.

B)Mitosis does not form membrane-bound nuclel.
C)Binary fission is not used by eukaryotes.
D)Binary fission is not a simple process.
Answer:
C
Explanation:

In the Venn diagram, the thing which is wrong with the diagram is Binary fission is not used by the eukaryotes. Thus, the correct option is C.
What is Binary fission?Binary fission is a type of asexual reproduction which involves the formation of new organisms which are similar to the parents. This process occurs by a separation of the body into two new bodies or organisms.
In the process of binary fission, an organism duplicates its genetic material that is deoxyribonucleic acid (DNA), and then divides into two parts through cytokinesis, with each new organism receiving one copy of the DNA. This process occurs in prokaryotes and eukaryotes.
Therefore, the correct option is C.
