Answer:
(autotrophs) need light, nutrients, CO2 (dissolved gases) to photosynthesize
Explanation:
The abiotic factors in the ocean help the ocean to 'work'. For example, phytoplankton (autotrophs) need light, nutrients, CO2 (dissolved gases) to photosynthesize. All of these factors are crucial to the primary producer!
Bacterial communities are an important part of biological diversity and biogeochemical cycling in aquatic ecosystems. In this study, the relationship amongst the phytoplankton species composition and abiotic environmental factors on seasonal changes in the community composition of free-living and attached bacteria in Lake Erhai were studied. Using Illumina high-throughput sequencing, we found that the impact of environmental factors on both the free-living and attached bacterial community composition was greater than that of the phytoplankton community, amongst which total phosphorus, Secchi disk, water temperature, dissolved oxygen and conductivity strongly influenced bacterial community composition. Microcystis blooms associated with subdominant Psephonema occurred during the summer and autumn, and Fragilaria, Melosira and Mougeotia were found at high densities in the other seasons. Only small numbers of algal species-specific bacteria, including Xanthomonadaceae (Proteobacteria) and Alcaligenaceae (Betaproteobacteria), were tightly coupled to Microcystis and Psephonema during Microcystis blooms. Redundancy analysis showed that although the composition of the bacterial communities was controlled by species composition mediated by changes in phytoplankton communities and abiotic environmental factors, the impact of the abiotic environment on both free-living and attached bacterial community compositions were greater than the impact of the phytoplankton community. These results suggest that the species composition of both free-living and attached bacterial communities are affected by abiotic environmental factors, even when under strong control by biotic factors, particularly dominant genera of Microcystis and Psephonema during algal blooms.

Answer:
Images for A certain beetle can have red spots or yellow spots or red and yellow spots. An RR beetle has red spots, an YY beetle has yellow spots, and an RY beetle has red and yellow spots.

Explanation:
The body's homeostatic control mechanisms ensure that a balance between fluid gain and fluid loss is maintained. The hormones ADH (antidiuretic hormone, also known as vasopressin ) and aldosterone play a major role in this.
Answer: Option B
Explanation:
The upper forelimbs of human beings and bats have similar skeletal structures but the same structure has resulted differently in whales.
This is because the natural selection in whales has resulted in change in anatomy and this change in whales has changed their anatomy.
The forelimbs of whales has changed into flippers and it helps whales in swimming.
The forelimbs of human beings, whales and bats have the common ancestors but because of different environment they evolved differently.
