Some Eukaryotic cells have internal structures that are able to use photosynthesis to convert light energy into chemical energy (as bonds in sugars). Why is this capability not found in all Eukaryotes? a. Once organisms are capable of eating and gaining their energy from consuming other organisms, energy from the sun is no longer needed in a contained ecosystem. b. The endosymbiotic event that brought chloroplasts into Eukaryotic cells actually happened after Eukaryotic lineages diverged so many lineages never actually possessed chloroplasts. c. The energy output from photosynthesis is not enough to support large and complex lifeforms d. Once mitochondria were incorporated into Eukaryotic cells, the need for chloroplasts was lessened e. As photosynthesis requires light, organisms that are active at night have less selective pressure to maintain chloroplasts within their cells. As such, after many generations, chloroplasts were lost from the cells and this is why we see so many organisms without them today.

The correct answer is the letter b. The endosymbiotic event that brought chloroplasts into Eukaryotic cells actually happened after Eukaryotic lineages diverged so many lineages never actually possessed chloroplasts

Explanation:

The plastid is an organelle linked to membarna found in the cells of eukaryotic organisms, which contains pigments used in photosynthesis. Some eukaryotic organisms over time have inherited the ability to photosynthesize from cyanobacteria by secondary endosymbiosis or ingestion, and are able to capture and sequester photosynthetic cells and chloroplasts, this process is known as kleptoplasty.

answer: decrease

a limiting factor is the one which decrease the abundance, distribution and causes extinction of the population of species in a ecosystem. here, predators including hawks, owls and snakes are the limiting factor for the population of mexican free tailed bat.   although bats are nocturnal animals as they forge for food at night these predators also may remain active during night which can decrease the population of the mexican free-tailed bats. also, these bats eat only one type of insects that are moths. the food can also be a limiting factor as all 400 members are dependent upon same type of food needs that are moths. the decrease in the moth population can cause decrease in population size of the mexican free-tailed bats.

therefore, the scenarios will most likely to decrease the population size of the mexican free-tailed bats.  

mass and weight are closely related because mass affects the weight of an object experiencing the effects of gravity. weight is the measure of the force of gravity on an objects's mass, while mass is the measure of how much matter there is in an object.
