(a) Aquatic ecosystems are rich in diversity. The life inside water is largely influenced by various abiotic factors. The abiotic factors are the chemical and physical components of an environment that affect the organisms living there. The primary abiotic factors that affect the life underwater are temperature, light and availability of oxygen.

(b) Oxygen available to the aquatic organisms is a detrimental factor. If less oxygen is available underwater aquatic animals will not be able to respire and die.

Light is also an important abiotic factor for underwater organisms especially for the aquatic plants. the aquatic plants underwater will not be able to make their food by photosynthesis if proper light is not available.

Temperature also plays an important role. Too low or too high temperature affects the metabolic activities of the organisms.

Depth of water body affects the availability of light and oxygen to the aquatic organisms. Shallow water bodies have light available to more aquatic organisms.

Complementary DNA? please help

topjm [15]

Answer: From top to bottom- T, C, G, A, T, A, T

Explanation:

These are the nitrogenous bases that make up a part of nucleotides in DNA.

There are 4 bases in DNA:

- Adenine

- Guanine

- Thymine

- Cytosine

The bases pair together from A to T and G to C, the way I remember is just reading it as AT GC and it works for me, but you make want to make an acronym if it helps you remember better.

As a result, all you have to do is type in the corresponding base to form the correct base pairs.

How many organelles are in plant cells? please list them. :)

Murrr4er [49]

There are 11 organelles in total,
vacuoles: they store water
Chloroplasts: trap energy from the sun to produce food for plant cell
Cell wall: provides support and protection to the cell membrane,
Cell membrane: thin flexible barrier around a cell, controls what enters/ leaves the cell
Nucleus: 'The control center', carries the DNA of the cell
Ribosomes: Found in all cells, their jobs are to make protein
Endoplasmic Reticulum: The internal delivery system of the cell
Golgi complex: Transports materials throughout the cell
Lysosomes: Break down food into particles the cell can use. another function is they destroy old or dying cells
Mitochondria: Breaks down food to make ATP
and last but not least cytoplasm a jelly like fluid in the cell that keeps the organelles suspended

As Virginia becomes more more populated construction of new homes has destroyed much of a force this has cause rivers and stream

AleksandrR [38]

Answer:

The correct answer is - water pollution.

Explanation:

In the US, water pollution is one of the most serious ecological problems, and sedimentation by filled with dirt, slit caused by development sites or construction sites. It is caused in the name of developing cities and states for new homes and other construction that is nothing but careless development that is causing water pollution in these areas including the Virginia.

The excessive silt has covered the spawning beds of fish causes spawning of the habitat. The dirt and slit and sediments cause inhibiting light to aquatic plants that result in less oxygen and food for aqautic life.

What is the difference between the predator-prey relationship and the<br>parasite-host relationship

jenyasd209 [6]

Answer: In a predator prey relationship, the predator kills and eats the prey. In a parasite/ host relationship, the parisite is feeding off the host, without killing it. If the host dies, the parasite will as well.
