please answer I still have 3 min only , Plants that live in shallow water have the same roles as plants on dry land. Describe the role of plants. Give an example of an interaction between one of the plants shown and another biotic element in the ecosystem.
The differentiating factor between water and land plants is that the land plants have larger root systems whereas several water plants lack a root system.
What are the roles of plants in shallow water and dry land?Plants that grow in dry areas have xeromorphic traits to reduce transpiration under drought stress.
Reduction in transpiration under drought stress conditions can also be attained through leaf shedding and decrease in leaf number, leaf size, and branching.
The shallow water, abundant light, and nutrient-rich sediment are the ideal conditions for the growth of plants. Aquatic plants then provide food and habitat for many animals such as fish, frogs, turtles, insects and snails.

A)more likely to produce an action potential
B)becomes less likely to produce an action potential
C)produces a stronger action potential
D)produces a weaker action potential
E)becomes more polarized
Answer:

An insufficient amount of oxygen causes the body to do lactic acid fermentation instead of cellular respiration
What is lactic acid fermentation and cellular respiration ?Cellular respiration is the process by which organisms combine oxygen with food molecules, rerouting the chemical energy in these molecules into life-sustaining processes while discarding carbon dioxide and water as waste products.
Anaerobic respiration (or fermentation) of the kind that produces lactic acid uses the breakdown of carbohydrates to create ATP as a source of energy. Because it takes place without oxygen, it is called anaerobic.When there is a lack of oxygen in the cell, skeletal muscle cells use lactic acid fermentation to renew these NAD+ molecules. Because they lack the mitochondria necessary to engage in aerobic cellular respiration, red blood cells must always regenerate NAD+ via lactic acid fermentation.Learn more about Cellular respiration here:

Why we can't live without sun?
Answer:
If the Sun disappeared or the Earth were flung out of its orbit the travel alone through interstellar space, then I think a small population of humans could survive (although we might need some advance warning).
While the surface of the Earth would freeze and become uninhabitable pretty quickly, there is enough internal heat in the core (left over from the formation of the Earth and generated by radioactive decay) that it would remain warm underground for billions of years. A small population (a few hundred people, maybe) could live in a suitably modified deep mine. With either nuclear power or geothermal power, they could power life support systems and grow food hydroponically. There are enough suitable deep mines for several of those survivor colonies.

What important function can elodea cells perform that onion cells cannot?'
Elodea cells is capable of photosynthesis, while onion cells cannot
difference between elodea cells and onion cellsElodea cells and the plant itself serve as producers in natural settings because they are photosynthetic plants. Plants use light energy to transform carbon dioxide and water into sugars and oxygen through a process known as photosynthesis. It is the primary pathway for energy to enter an ecosystem.
Elodea cells photosynthesize because they develop in sunlight and are frequently categorized as waterweeds.
Onions cells, on the other hand, grow below the surface, therefore their cells cannot photosynthesize. Additionally, elodea cells have a vacuole that is filled with cell sap, a fluid that is mostly composed of water.
Conclusively, Elodea cells are structurally distinct from onion cells. Elodea cells are arranged in two layers, one of which is long and narrow and the other of which is short and wide. The cells of an onion are bigger and arranged in a single layer.

Why might it be advantageous for a sessile (non-motile) Cnidarian to have radial symmetry?
It is advantageous for a sessile (non-motile) Cnidarian to have radial symmetry. Animal body parts are radially symmetrical and they are arranged along a central axis so each part extends from the center.
Because of having radial symmetry the animal body parts can be identically cut along the central axis. Animals having radial symmetry are incapable of moving and sessile. Radial symmetry helps out to reach every corner of their body parts. Cnidarians contain two tissue layers. The outer layer is called the epidermis. The epidermis is formed from the ectoderm. The inner layer, which is called the gastrodermis, which secretes digestive juices into the inner parts called the gastrovascular cavity. This gastrodermis is formed from endoderm. Cnidarians do not have to contain mesoderm and Hence cnidarians do not have organs.

Answer:
A
Explanation:
Hello, so we can do this question two ways. 1, we can know what kind of relationship the two types have or 2, we can analyze each relationship and see if it would increase or decrease.
Starting with option 2, we can look at A. A says the population would stay stable because of a commensal relationship. In a commensal relationship, one party benefits and the other neither gains or loses anything. Thus, A could be true because the population would stay stable in this case.
Looking at B, we see it says the population would increase because it has a mutualistic relationship. However, in a mutualistic relationship both species benefit. If the wrasse population died more, that would NOT benefit the other species in a mutualistic relationship, thus B can be eliminated.
Answer C says it would decrease because of its predator and prey relationship. Depending on which one was the predator and which was the prey, one species could benefit from the death of the other while the other didn't. For example, if the wrasses were the prey, the predators would also decrease because they could not eat as well, but if the wrasses were the predators they other population would increase because they would be eaten less. Thus we cannot rule out answer C.
D for an answer is like C, depending on the roles of which was which D could or could not be the answer.
Although method 2 helps eliminate B it still does not tell us the answer, so we look to our knowledge of wrasses and titan tigerfish. Wrasses and titan tigerfish have a commensal relationship. Therefore, one can benefit and the other is neither harmed nor benefited. This relationship is also called symbiotic. Thus, the wrasse population could decrease and since the titan tigerfish do not experience benefits or harm from that species their population will remain the same.

The human body produces 60 billion (60,000,000,000) new cells per day. How many cells does it produce in one hour?
Answer:
E.g. E. coli—20 min, so in an hour 1 cell would turn into 8.
Given that 60 billion cells are produced in a day in the human body, the number of cells that will be produced in an hour can be calculated by dividing the number of cells by the number of hours in a day. There would be approximately 2.5 billion cells produced in one hour.
How frequently are the cells in our body renewed?The human body regularly replaces its own cells. Every day, roughly 330 billion cells, or 1% of all our cells are replaced. The equivalent of a new you will have been replenished in 80 to 100 days with 30 trillion.
Each second approximately one million cells of the body die which means 1.2 kg of the cells are destroyed each day. All the cells in the body have a definite lifespan after which they are replenished.

What is frequency ?
The quantity of waves that pass a set location in a predetermined period of time is known as frequency. Therefore, if a wave passes through in half a second, the frequency is 2 per second. The frequency is 100 times per hour if it takes 1/100 of an hour.
The temporal rate of change observed in oscillatory and periodic phenomena, such as mechanical vibrations, audio signals (sound), radio waves, and light, is specified by the frequency, an essential parameter in science and engineering.
v = f λ
v = velocity of the wave
f = frequency
