Answer: B
Explanation: It is the question 2 that can be answered using scientific process. scientists can better explain the effect of plastic bags on birds.
The other question can be answered by research or logics.
Answer:
Arrow O
Explanation:
The question states that the substance is starting out with high energy (gas) and lowers energy to something that is still able to "slide" or flow, a liquid.
The change is moving from gas to liquid
The initial assessment of bats suggested they lacked the ability to synthesize vitamin C (Birney, Jenness, and Ayaz 1976). However, several recent studies have shown that approximately two thirds of different bat species have functionally expressed GULO genes (Cui et al. 2011a; Cui et al. 2011b). The various bat taxon taxa that lack the ability to make vitamin C have varying levels of deletion degradation in their GULOgenes and the patterns of sequence variation show that they are lineage independent events. Trying to explain the discontinuous GULO deletion patterns within a common descent paradigm has produced a variety of difficult contradictions for a coherent model of bat<span> evolution </span>(Cui et al. 2011b).
Loss of vitamin C pathway function and GULO gene degradation has also been detected in guinea pigs, great apes, and humans (Lachapelle and Drouin 2011; Nishikimi, Kawai, and Yagi 1992; Nishikimi et al. 1994; Ohta and Nishikimi 1999). In addition, naturally occurring scurvy and osteogenic disease pathologies related to GULO inactivating mutations and large-scale deletions have been documented in rats, mice, and pigs (Harris et al. 2005; Hasan et al. 2004; Jiao et al. 2005; Kawai et al. 1992; Mohan et al. 2005). Thus, degradation of the GULO gene in a wide array of mammals and birds is a relatively common occurrence.
Answer:
Because the quantities of phosphorus in soil are generally small, it is often the limiting factor for plant growth. ... Phosphates are also limiting factors for plant-growth in marine ecosystems, because they are not very water-soluble. Animals absorb phosphates by eating plants or plant-eating animals.

Answer:
1. The species that can produce their food with the assistance of light energy coming from the Sun are termed as autotrophs. These species tend to produce chemical energy from light energy. Heterotrophs on the other hand refer to the species that lack the tendency of generating their food and are solely reliant upon the autotrophs for food.
2. The phenomenon that utilizes water and carbon dioxide and produces carbohydrates within the plants is known as photosynthesis. In the process, oxygen is also produced as a byproduct. The produced oxygen is further utilized by other species in the process of cellular respiration.
3. In the life of an organism, both oxidation and reduction perform an essential function. In the process of photosynthesis, the reduction of carbon dioxide is done and oxidation of water molecules is done. Therefore, it can be said that photosynthesis is an illustration of the oxidation-reduction reaction. Similarly, in cellular respiration, the molecules of oxygen are reduced and the molecules of glucose are oxidized, thus, it is also an illustration of an oxidation-reduction reaction.
4. In the light reaction phase of photosynthesis, the production of ATP, that is, the source of energy is done. Further in plants, the utilization of ATP is done to fix carbon dioxide within the glucose. In the process of cellular respiration, the energy within the carbohydrates is utilized to generate ATP at the time of the electron transport chain.
