During rain events, runoff brings an excess of nutrients (that have collected and become
stagnant on land), like nitrates, into the ocean. This spike in nutrients is called eutrophication.
Think of the effects of this change and answer the questions below:
a. Nitrogen is often the limiting factor in an environment for photosynthetic autotrophs (such as
plants and algaes). Draw a logistic growth graph representing the population of algae in the coastal ocean.

Answer:

The seedling forms a hypocotyl hook that pushes through the soil. Once the seedling reaches the light, the hook opens to create a straight seedling. The cotyledons function as the repository for food reserves in the seed.

It was estimated that Americans were consuming 200 billon more calories than was required and that this was enough to feed an additional 80 million people.

Answer:

1. The lack of clean water can affect people's lives because people use water for everyday things. If people do not shower with clean water, then what is the point of showering at all? Also, people use water to cook, so if people are using dirty water then you could get sick. Some people do not buy water, so you would have to boil the water each time you want to drink it. This is how a lack of clean water could affect people's lives.

2. There are many things that could change people's lives positevly. For example, if you move to a new state where it is warmer. If you go to a new school you could make new friends. Also, somebody new could move in down the street and you could have more friends. Even something as small as eating your favorite meal for dinner could change your life. You could remember it as being amazing. These are how changes (small and large) could change somebody's life.

Explanation:

Humans use their lungs to inhale oxygen from the air. But worms, fish, crabs and other underwater animals use gills to get oxygen from the water. As water moves across an animal's gills, oxygen is removed and passed into the blood. Gills work better when there is more oxygen in the surrounding water.

Answer:

The six limbs shown in the image have a similar bone arrangement, but the size and shape of the bones vary among the organisms. The structures in the image serve different functions for each organism. Flippers helps whales swim, and arms help humans use tools. Horses and lions use their legs for support and movement, and a frog uses its legs to jump. Wings help birds fly.

A shift in species composition to less salt-tolerant plants is the most likely long term effect.

The salt tolerance test is performed using Tryptic Soy Broth with added sodium chloride (regular table salt) to create an overall salt concentration of 6.5%. It is a selective medium which tests the ability of an organism to survive in a salt-rich environment.

The salt tolerance of a plant is often defined as the degree to which the plant can withstand, without significant adverse effects, moderate or high concentrations of salt in water on its leaves or in the soil within reach of its roots.

Hypersensitivity to catecholamines may be the cause of salt sensitivity. A low sodium concentration in saliva deserves further study as a simple screening test to identify salt-sensitive subjects.

water can exist in three states; liquid, solid and gases.

Explanation:

At temperature below zero degree Celsius, water exists as a solid but as it absorbs temperature from Its surroundings, it undergoes melting and turns into liquid water. More application of heat makes it boil leading to the evaporation and vapourisation of water molecules( note: evaporation occurs at all temperature).

Answer:

Cell membrane surround cells, but cell wall is an extra covering outside plant cells, made up of cellulose

A cell plasma membrane and cell wall surround the eukaryotic cell.In the animal cell, there is a plasma membrane. In the plant cell, both the plasma membrane and cell wall are present.

The plasma membrane is the outermost covering of the cell that restricts the movement of molecules across the cell. In eukaryotic cells, the plasma membrane is hydrophobic by nature. It has carriers and ion channels in it. The plasma membrane has proteins, glycolipids, glycoproteins, etc. Apart from this, the plasma membrane of animals has cholesterol.

The plant has a cell wall outside of the plasma membrane. The cell wall is made up of cellulose. The polysaccharide cellulose is composed of glucose monomers.The cell wall is more rigid than the plasma membrane. The cell wall is present in some bacteria and fungi, but the composition of the cell wall is different from that of the eukaryotic cell.

Hence, the cell is surrounded by the plasma membrane and cell wall in eukaryotes.

The answer is "[tex]\bold{lacI^{+} lacP^{+} lacO^{+} lacZ^{-} lacY^{-} lacA^{+}}[/tex] "

Explanation:

In this question, the prescribed mutant E. Coli does not express the lacZ gene, so beta-galactosidase doesn't quite exist. Therefore in a particular strain, there is also the potential of lacZ– and that only the genetic makeup indicates its production of lactose. Therefore the above-mentioned option is correct.
