Flatworms

James H. Thorp, D. Christopher Rogers, in Field Guide to Freshwater Invertebrates of North America, 2011

B Reproduction and Life History

Some flatworms, especially those living in temporary aquatic habitats, reproduce only once per year (univoltine), while other species are multivoltine, with the number of generations depending on environmental favorability. Most flatworms reproduce sexually, and almost all species are hermaphroditic. Although gamete exchange is most common, self-fertilization is possible in some species. Eggs are laid singly on a hard substrate, are grouped into clusters (sometimes stalked), or are placed in cocoons. Miniature flatworms emerge from eggs which have been attached to the substrate. These usually develop directly (without intermediate larval stages) into adults and differ only in size and presence of reproductive organs. A few species are ovoviviparous (young brooded inside parent) or have a distinct larval stage. Asexual reproduction occurs seasonally in many taxa and is the only form of reproduction in a few species. This form of reproduction involves differentiation of the adult body into distinct units (zooids) followed by separation into small flatworms via transverse division of the adult body. This process is aided by the remarkable regenerative abilities of flatworms.

Under demanding environmental conditions, flatworms produce resistant eggs able to survive desiccation of the surrounding environment or the animal may enter diapause (a very low metabolic state) and encyst as a whole animal or fragment of the adult.

Sexually reproducing flatworms can live from a few weeks to a few months (not counting periods of encystment), while the life span of asexual species is theoretically indefinite.

Plants remove carbon from the atmosphere in the form of CO2 and store it in their structures. How can rapid deforestation affect the carbon cycle? What can be done to reduce the effects? Explain.

Answers

Answer:

Explanation:

Deforestation affects carbon cycle through the Greenhouse gas effect and global warming. Green plants, trees and forest helps to balance the amount of Carbon in the atmosphere, carbondioxide is used up by plant through the process of photosynthesis in which plants make their own food. When there is excess amount of carbon dioxide in the atmosphere as a result of deforestation ‘blanket’ of carbon dioxide is formed which traps heat and prevents it from leaving the earth surface in the atmosphere. This accumulated heat leads to global warming in the environment.

More trees should be planted to prevent rise in atmospheric a carbon and deforestation should be prevented.

Answer:

Deforestation has an effect on the Carbon Cycle also known as the Greenhouse gas effect and global warming. Trees and forest balance the amount of Carbon in the atmosphere through the process of photosynthesis in which plants make their own food with carbon dioxide. And when we remove the plants that turn CO2 into breathable air we have more CO2 over all.

SCIENCEEEEEEEEE Frieda makes a pyramid of oranges for a display at the grocery store. A few minutes later, Corwin bumps into the display and the oranges spill down. Which change of state does the motion of the oranges most closely model?

Answers

The correct answer is A. Melting

Explanation:

Melting occurs in solids as these change their state to liquid state, usually due to high temperatures. For example, if one cube of ice is exposed to heat it melts. This physical change implies the solid loss its defined shape and particles in it are not as organized as before.

This process is exemplified by the situation of the oranges because the pyramid of oranges had a defined shape and the oranges were arranged in a defined pattern; however, in the end, this shape changes, and the particles (oranges) are no longer organized in a strict pattern. Also, the distance between particles increases, which also happens when solids become liquids.

A personal trainer thinks her clients get better workouts and are stronger if they listen to music while working out. Over the next week, she divides her 20 clients into two groups of 10. For the first group, she plays music and sees if they can lift a barbell weighing 50 lbs. For the second group, she repeats the test but does not play any music. All 10 members of the music group could lift the barbell, but only 7 members of the no music group could lift the barbell. She concludes that her hypothesis was correct and decides to always play music for her clients.



Which group was the control group?

Answers

Answer:

The correct answer is: the group of 10 people that lifted the barbell with music is the control group.

Explanation:

The personal trainer made an experiment to test her hypothesis. When experiments are being made, is common to have a control group and an experimental group.

The control group is the one that is subjected to the usual conditions, the group that shows what normally happens. The experimental group is the opposite, this group is observed while it goes through an unusual condition that may impact how they perform in the task observed.

The personal trainer thinks that playing music for her clients is of benefit to them, so we can assume that she always plays music during the workouts, which means that the control group is the one that is listening to music while lifting a barbell. The group that worked out without music is the experimental group because they were the ones that performed that activity with a change in their normal environment.
