The nervous system has electrical cells that are trained to transmit and receive messages. Through the use of electricity, people can communicate by transmitting messages to one another. This voltage is produced in neurons by the movement of charged ions. salt atoms with positive or negative charges that pass through the cell membranes and cross the cell's outer membrane. The neuron has dendrites, which are branches (like a tree) that receive messages, and an axon, which is a longer, more straightforward projection (like a tree trunk), that sends information. Synapses. Axon ends include the neuron communication junction, where vesicle fusion releases chemical signals. Neurotransmitters are the chemical messages that the nerve cell releases.

What is invasive plants ?
(Write a lot and don’t use big words)
An invasive plant is a plant that is not native to the region it is growing in. For example, English Ivy is native to Europe but has invaded the North Western coast of North America.
Explanation:Characteristics of Invasive Plants
Invasive plants are usually very fast-growing. Their population can be hard, if not impossible to control. Additionally, like all invasive species, invasive plants place a strain on their environment. One way or another, invasive plants hurt the ecosystem they are in. This can involve the invasive plant taking up resources from native plants and/or being toxic to native animals.
We can see these characteristics in English Ivy. Like most ivies, English Ivy grows on trees and other large plants. English Ivy can become so overgrown that it weighs down the plant it is grown on. This extra weight can kill native plants. Also, due to the speed at which Ivy spreads, environmentalists have been unable to eradicate English Ivy from North America.
Causes of Invasive Plants
In almost every instance of invasive plants, the cause is human action. Through travel, humans bring seeds and plants to regions they are not native to. Then, in some cases, the plant will begin to grow rapidly and become invasive.
English Ivy was brought to North America during the Columbian Exchange.
The Columbian Exchange was the exchange of vegetation and livestock between Europe, Africa, and the Americas during the Age of Colonialism. Many invasive species can be tied back to the Columbian Exchange.English Ivy was then used as decoration both indoors and outdoors. Since then, it has grown into a dangerous invasive plant.
Which are the two types of Location?
There are two types of location-
Relative locationabsolute locationDefine relative location.A person or place's placement in respect to another object or location is referred to as their relative location. Cost, wait time, or distance all affect relative location. Map the distance between Salt Lake City, Utah, and the Computer History Museum, for instance, in California. The distance from the relevant position would be 767.7 miles, which would require a journey duration of 11 hours and 40 minutes.
Define absolute location.An accurate and precise point that pinpoints the precise location of a given object or area is known as an absolute location. Geographic coordinates, such as longitude and latitude, are frequently used to describe absolute positions. A specific object's precise location in reference to the prime meridian and the equator can be determined using geographic coordinates.

Suppose
if we have more than 50% recombinant frequency in any case, then what
would be the best interpretation of that case?
A. Gene are present on same chromosomes
B. Genes are linked
C. Genes are having possibility of crossing over
D. Genes are present on different homologous pair
All options are correct, expect option B.
The frequency of a single chromosomal crossover occurring between two genes during meiosis is known as the recombination frequency. The measure used to describe recombination frequencies of 1% is the centimorgan (cM).Genes that are near to one another tend to be more connected than genes that are farther apart. The frequency of recombination will decrease with increasing linkage and vice versa. Linkage thereby lowers the frequency of the hybrid.A 50% recombinant frequency indicates that the genes are present on the same chromosome but are far from one another, suggesting that more than one crossover may have occurred during each meiosis. They might not be related because they are on different chromosomes. There is independent assortment in these genes.Therefore, all the options expect B. are correct.

HELP ME ASAP 18. Why do animals in cold environments need a lot of lipids in their cells? ok
Answer:
As temperature increases, so does phospholipid bilayer fluidity. At lower temperatures, phospholipids in the bilayer do not have as much kinetic energy and they cluster together more closely, increasing intermolecular interactions and decreasing membrane fluidity.
Explanation:
When temperature decreases, the composition of membrane lipids (phospholipid fatty acids) is expected to become more unsaturated to be able to maintain homeoviscosity.

Jamal and Sarah are investigating osmosis in potatoes. The drawing shows their *
experimental setup. They immersed a firm, freshly peeled potato into a container
with a solution provided by their science teacher, Ms. Stewart (Fig. 1). The next
day, they observed that the potato had shrunk and softened (Fig. 2). Describe the
nature of Ms. Stewart's solution and why the potato shrank?
Fig. 1
Your answer
24 hours
Fig. 2
The result of the experiment suggests that Ms. Stewart's solution was hypertonic, and that the potato shrunk because water moved by osmosis in favor of its concentration gradient from the potato to the solution.
What is osmosis?
Osmosis is a simple diffusion transport that occurs when water moves from a more diluted solution to a less diluted one through a semipermeable membrane.
When two solutions of different concentrations are separated by a membrane (with the same properties as the cell membrane), the only molecule allowed to pass from one side to the other is water (not solute molecules).
Water goes from the hypotonic solution (less concentrated) to the hypertonic one (more concentrated), and keeps doing so until concentrations on both sides get equal.
In the exposed example,
A fresh potato was placed on a solution of unknown solute concentration.
There were two options for this potato,
If the solution was hypotonic to the potato, the potato would have gained water. This means that water would have moved from the solution to the potato, and this last one would have swelled.
If the solution was hypertonic to the potato, the potato would have lost water. This means that water would have moved from the potato forward to the solution, and the potato would have shrunk.
After a day, Jamal and Sarah noticed that the potato shrunk.
This result suggests that Ms. Stewart's solution was hypertonic and that the potato shrunk because water moved by osmosis in favor of its concentration gradient from the potato to the solution.

You need to find out why the GBR water is inhibiting (stopping) photosynthesis in the algae. The three major parts of photosynthesis are PSI, PSII and the Calvin cycle. The database has provided 3 things that could be inhibiting photosynthesis: high sea temperatures, paraquat, and diuron.
Explanation:
If the temperature increases then that will decrease the sugar but not the ATP and NADPH. So I predict that diuron will inhibit the photosynthesis because if photosystem II is infered with it then photosynthesis wouldn't work.And also, because paraquat will lower the NADPH and sugar but not ATP. Hence Diuron is the only choice left.

3) Why should we store seed in moisture proof polythene bags
The orthodox seeds can be put in sealed moisture-proof containers after being dried to the proper moisture content. This avoids the need for prolonged dehumidification.
When refrigeration is used to maintain controlled low temperatures and moisture-proof containers, long-term storage is most successful. When refrigeration is used to maintain controlled low temperatures and moisture-proof containers, long-term storage is most successful. Generally speaking, storage life shortens as seed moisture content rises. Low moisture level—below 4%—can also harm seeds due to excessive desiccation or result in hard seededness in some crops. If seeds are kept at high moisture content, losses could be very quick due to mould growth. The seed will mold as a result of the retained moisture, ruining the sample. Keep them cold and dry to increase their shelf life. Seeds quickly absorb moisture again. Keep seeds in airtight containers like tin cans or glass jars with tight fitting lids to maintain dryness.
