<span>The 4-human related threats to seagrasses are caused mostly by human development. The most common are: Excessive dredging, careless boating, chemical waste in the sewers, and garbage.<span>

a. Excessive dredging due to the accommodation of building houses or other facilities that need proper sewage disposal has caused the destruction of many seagrasses and mangrove communities in the United States. 

b. Careless boating by boaters in the area who are not familiar with the local waters destroy the seagrasses with their propellers. To further prevent destruction, they are encouraged by the local government to familiarize themselves with the area and prevent boating in shallow waters where seagrasses are found.

<span>c. Chemicals found in the sewage system that leak cause the growth of excessive algae and bacteria. When this happens, they cover the surface area of the water causing little to no sunlight to appear underwater and reach the seagrasses. When this happens, seagrasses lack the capacity to produce oxygen through photosynthesis. Not only does this affect seagrasses but also marine life, when algae and bacteria build up they suck the oxygen that is necessary for the survival of various marine animals. </span>

<span>d. Garbage that decompose in land or in water produce poisonous chemicals that are also a threat not only to seagrasses but also to other marine life. </span></span></span>

25% is the approximate production efficiency of this animal

Explanation:

Given ,

A ladybug eats 200 J of plant material

100 J is eliminated as feces

75 J are used in cellular respiration,

Now,

The approximate production efficiency of this animal :

200 - (100 +75) = 25 %

Do you think molecules are larger or smaller than a cell in the human body?

Answer:

Yet you can turn up the magnification for an even closer look: Cells contain molecules that are made up of even smaller components called atoms. Figure 1: Levels of the body from smallest to largest: Atoms, molecules, cells, tissues, organs, and organ systems.

how are mutations continually being generated in a population (what are some of the causes of mutatuions?) explain
vampirchik [111]
Some causes could be the mother smoking, drinking, doing drugs etc. Or even simply her body doesn’t fully accept the baby growing inside her so it acts out against it. Sounds strange but it happens. Also if the mother is sick with Zika or another virus, it can harm the baby’s growth.

A forest has two groups of plants that appear to be very similar both phenotypically and genotypically. The major difference is
Gennadij [26K]
The basics would be that you'd need to find out if they could exchange genetic information. If not, they couldn't be considered part of one species. Set-up 2 artificial environments so both groups would produce pollen at the same time. Fertilise both plants with the other's pollen. Then fertilise the plants with pollen from their own group. 
Count the number of offspring each plant produces. 
If the plants which were fertilised by the opposite group produce offspring, they are of the same species. You can then take this further if they are of the same species by analysing if there is any difference between the number (and health) of offspring produced by the crossed progeny and by the pure progeny. You'd have to take into account that some of them would want to grow at different times, so a study of the progeny from their first sprout until death (whilst emulating the seasons in your ideal controlled environment). Their success could then be compared to that of the pure-bred individuals. 
Make sure to repeat this a few times, or have a number of plants to make sure your results are accurate. 
Or if you couldn't do the controlled environment thing, just keep some pollen one year and use it to fertilise the other group. 
I'd also put a hypothesis in there somewhere too. 
The independent variable would be the number of plants pollinated. The dependant variable would be the number of progeny (offspring) produced.
