There are multiple factors which controls the nitrogen and other nutrients presence in soil for the good growth of plants, one of them is the selection of right kind of plants which fixes nitrogen more efficiently than others.

These are the few plants which are good nitrogen fixing plants such as:

- Lupines, cowpea, fava bean, alfalfa  

- Tall trees such as black alder, black locust and empress tree  

- Shrubs and shrt trees such as autumn olive, Gumi, Siberieam pea shrub, Russion olive and Sea berry

Use the following terms to describe in detail how you visually perceive an object that you can see right now.

Answer: To see for example an apple first light that passes through the pupil is eventually reflected on the pupil, activating neurons in the retina. light waves that were reflected off the apple are changed into neural impulses (transduction) at the point of the retina, where neurons fire in response to light waves. Action potentials are released when neurons fire, sending an electrical charge through the neuron. Excitatory neurotransmitters are released when the action potential reaches the axon terminal, and that these neurotransmitters increase the chances that the next neuron will fire. Of course the neural message from the retina first passes through the thalamus, and then the thalamus routes the impulse elsewhere in the brain.

I hope it helps, Regards.

Easy points 1 suggest what the drug longmasterol might do to the body to affect reaction time 2describe the effect of longmaster
Semmy [17]

Answer:

4.Antagonistic muscles are muscles that have opposite effects to one another,As one relaxes, the other contracts.

5, This is to move bones in tandem to cause locomotion.As as one contracts, and the other relaxes, the bone is pulled and this shifts the position of the bone to cause locomotion.Note, a muscle cell usually pull in one direction.,

6. it lacks nucleus to have enough space for oxygen carrying molecules(haemoglobin)it has bi-concave shape to squeeze through tinny capillaries to reach tissues and have large surface area for oxygen carriage.They contain Oxygen carrying pigment Haemoglobin.

1.This is a stimulant that increases the rate of excitability by increasing the synaptic connection through increase in amount neurotransmitters, at synaptic junctions

2,This accelerate the rate of ageing.Leading to premature aging.it ,may affect the heart efficiency and the entire cardiovascular system at the long run.

3. After a period of time this may cause liver damage by blocking blood flows to the liver.It may also lead to inhibitory effect of detoxification activities of the liver.This leads to hepatic failure.

7. A state of matter can only be compressed at  the gaseous state.it can not be compressed at solid because the inter molecular forces are very strong and the molecules of solids are well compact. Molecules of liquids are not free neither, although their molecular force are weak, But the molecules can not be compressed, since they lack random motion.

8. This is due to the lattice arrangement of water molecules in ice, resulting in lesser density of ice compare to that of water. The lower density of ice makes ice to float when it freezes, however, it is the higher lattice arrangement in ice which makes it expand, compare to other liquids which makes it less dense and therefore floats.

10. This can be caused by the force that pull water through the mains to the pipes.it is measures in bars. Thus 1 bar is equal to the force per unit area lifting water to a height of 10 meters.

9. This is to generate a forward thrust, to overcome the aerodynamic drug.The propeller engine generate a thrust, which ensure a steady speed  large enough to overcome the drag

List two additional populations (other than those listed in the lab) for which
omeli [17]

Indirect methods like mark and recapture become a strong tool to estimate population size or density in species on which it is impossible to apply a direct methods. <em>Because of their biological and ecological characteristics, the Gypsy moth and the Green lizard populations are good examples  for which  mark and recapture would work well.</em>

<em>------------------------------------------------------</em>

There are different methods to study population density. There are direct methods and indirect methods. Among these last ones, we might find the Mark-Recapture technique.

The Mark-Recapture technique assumes that

  • <em>the population is closed during the sampling season, there is no mortality nor natality, </em>
  • <em>marks in the individual last the whole sampling season, and they do not affect the marked individual or their behavior. </em>
  • <em>marked individuals are randomly distributed in the population, and </em>
  • <em>all the individuals have the same probability of being sampled.</em>

The method consists of capturing a sample of individuals belonging to the population under study. After capturing the individuals, the researcher marks and releases them again. The third step is to sample again: The researcher captures new individuals and counts how many of them are marked. These marked individuals belong to the first sample.

Indirect methods like this become a strong tool to estimate population size or density in species on which it is impossible to apply a direct method such as <em>counting individuals</em>.

For instance, if we need to estimate insects population density (<u><em>Gypsy moth population</em></u>) or reptiles population density (<u><em>Green lizard population</em></u>) because of their biological and ecological characteristics, the best way of doing it is by applying indirect methods. <em>These species characterize as small-sized, fast to escape, they can hide in small inaccessible places, they have nocturnal habits, their reproductive rate is too high, and their distribution rate is wide. </em>Among many other characteristics, their population density can not be estimated by direct methods. Mark-Recapture technique is the most suitable one.

What type of plant would be least affected by the loss of the guard cell function that closes stomata?.
maks197457 [2]

A rainforest plant would be least affected by the loss of guard cell function that closes the stomata.

<h3>What is Guard Cells?</h3>

Guard cells are types of specialized plant cells present in the epidermis of leaves, stems, and other organs that are used to control gas exchange.

They are produced in pairs with a gap between them that forms the stomatal pore. They are kidney-shaped cells that surround stomata and control the opening and closing of stomata.

When there is an excess of water in the plant, the guard cells swell and form a hole for the exchange of gases.

Thus, a rainforest plant would be least affected by the loss of guard cell function that closes the stomata.

If you used a slingshot to launch a bowling ball and a baseball with the same force, which would go further? Explain your reason
Alex Ar [27]

Answer: The baseball will go farther because of Newton's law. The more mass an object as, the more force needed to move it. The bowling ball has more mass than a baseball so more force is needed to move it.
