Answer:
1. produces genetic variations.
2. produces resistance to unfavorable conditions.
3. produces disease-free seed plants.
Explanation:
Sexual reproduction causes more genetic variation. More genetic variation results in diverse immune systems and traits that are advantageous to survival. Variation is good because it allows a species to adapt to new environments.
The advantages of sexual reproduction is produces resistance to unfavorable conditions, produces genetic variations and produces disease-free seed plants.
What do you mean by sexual reproduction?Sexual reproduction is a type of reproduction that involves a complex life cycle in which a gamete with a single set of chromosomes combines with another gamete to produce a zygote that develops into an organism composed of cells with two sets of chromosomes.
A disadvantage is that sexual reproduction takes longer than asexual reproduction. A mate must be found, the egg must be fertilised by sperm, and then the offspring develop.
Three mechanisms contribute to genetic variation arising from sexual reproduction: independent assortment of chromosomes, crossing over, and random fertilization.

birds and mammals are both endothermic. i.e. they maintain body temperature internally through metabolism rather than from the environment. how would you explain this, given the position of the two groups of animals on the phylogenetic tree?
On the phylogenetic tree, (a diagram used to show relatedness among organisms) the birds and mammals are closely related to each other and they both are characterized as endothermic.
Given the position of the two group of animals on the phylogenetic tree, their similarity with regards to maintaining body temperature is due to the fact that their evolution involves a more recent ancestor compared with the other vertebrates.
As organisms evolve beginning from invertebrates through to vertebrates, the body system becomes more complex and as they evolve within the vertebrate group.
Some vertebrates like reptiles and amphibians that were dependent on the environment to regulate their temperature while others like birds and mammals forms complex system that enable them live on land and regulate their temperature independent of the environment.

I know I'm late but I too am taking the Phenomenon #2 Assessment (Part 1) and want to help any future readers : )
(I pretty much gave you guys the answer but the little facts might still help, so I didn't give the direct answer in the start)
Explanation:
Mitosis: A type of cell division that results in 2 identical daughter cells.
* Process responsible for us getting bigger
*Process that repairs damaged cells
*grows new skin for us when cut
(took this out of my teachers lesson/ CC)

You hear rumors about an unusual series of four islands in the Tierra del Fuego archipelago of Chile. On these islands, the typical laws of island biogeography theory are reversed such that species colonization rates are influenced by island size, not isolation, and small islands have higher colonization rates than larger islands. In addition, islands close to the mainland have higher extinction rates than islands far from the mainland. Of the four islands in this archipelago, a _____ island _____ the mainland would have the SECOND LOWEST equilibrium number of species.
Of the four islands in this archipelago, a SMALL island CLOSE TO the mainland would have the SECOND LOWEST equilibrium number of species. Biogeography studies species distribution.
Biogeography refers to the discipline that examines the range of distribution of species and taxonomic groups in a given geographical area over geological time.
The theory of island biogeography is a scientific theory that posits the idea that larger islands exhibit a greater amount of species (i.e., higher biodiversity) than smaller islands.
According to this theory (island biogeography), each island represents a particular unique ecosystem, which is different from other surrounding ecosystems.

why are carbon atoms important in organic molecules
What molecules are required for the Calvin cycle? (3 answers)
Answer:After the energy from the sun is converted and packaged into ATP and NADPH, the cell has the fuel needed to build food in the form of carbohydrate molecules. The carbohydrate molecules made will have a backbone of carbon atoms. Where does the carbon come from? The carbon atoms used to build carbohydrate molecules comes from carbon dioxide, the gas that animals exhale with each breath. The Calvin cycle is the term used for the reactions of photosynthesis that use the energy stored by the light-dependent reactions to form glucose and other carbohydrate molecules.
Explanation:The Interworkings of the Calvin Cycle
In plants, carbon dioxide (CO2) enters the chloroplast through the stomata and diffuses into the stroma of the chloroplast—the site of the Calvin cycle reactions where sugar is synthesized. The reactions are named after the scientist who discovered them, and reference the fact that the reactions function as a cycle. Others call it the Calvin-Benson cycle to include the name of another scientist involved in its discovery (Figure 5.14).
This illustration shows that ATP and NADPH produced in the light reactions are used in the Calvin cycle to make sugar.
Answer:
CO2, ATP, and NADPH
