Humans have good memory because of their brain, one part of the human brain has a function just for memory!
Answer:
The correct answer is - All plants share a similar life cycle
Explanation:
The sperms that the bryophytes are biflagellated whereas in ferns these are multi-flagellated that helps in the swimming to the archegonia or female part to perform the fertilization, due to the presence of water.
The sperms in cycads also have flagella for the same purpose of swimming in the pollen tube. The ferns and the bryophytes both require the same or similar life cycle that includes the flagella and water for the formation of the zygote.
The most probable future changes in the global climate are:
- Global warming;
If the levels of CO2 and methane increase enough in the atmosphere to be able to intensify the Greenhouse effect, than some portion of the ice on the planet will melt because of the rising temperatures, thus lifting up the sea level, creating more unpredictable weather with larger and stronger storms, but also making the mainland much drier. This would be a scenario if the continents are arranged like they are now, but if there isn't a sufficient mass of land on and around the poles, than all of the ice will melt and the sea levels will rise so much that the planet will come in the ''water planet'' scenario, and it will have wet tropical climate pretty much everywhere on the planet.
- Ice Age;
If there's a disruption in the warm ocean streams and some of them disappear, or the levels of nitrogen or oxygen increase in the atmosphere, the Earth will start to cool off, thus coming to a situation of an Ice Age. In this kind of situation, there will be large ice sheets on and around the poles that are stretching much further towards the lower latitudes, as well as mountains all over the world that are covered in snow and shaped by glaciers.
Answer:
Explanation:
Let the frequency ,
Now the unit of frequency is hertz = s⁻¹ = T⁻¹ where T is time, tension T = kgm/s² = MLT⁻¹ and linear density m = kg/m = ML⁻¹.
So,
![T^{-1} = L^{x}[MLT^{-2} ]^{y}[ML^{-1} ]^{z}\\](https://tex.z-dn.net/?f=T%5E%7B-1%7D%20%20%3D%20L%5E%7Bx%7D%5BMLT%5E%7B-2%7D%20%5D%5E%7By%7D%5BML%5E%7B-1%7D%20%5D%5E%7Bz%7D%5C%5C)
collecting the like bases, we have
![T^{-1} = [L^{x + y -z}][M^{y + z} ][T^{-2y} ] \\L^{0} M^{0} T^{-1} = [L^{x + y -z}][M^{y + z} ][T^{-2y} ]](https://tex.z-dn.net/?f=T%5E%7B-1%7D%20%3D%20%5BL%5E%7Bx%20%2B%20y%20-z%7D%5D%5BM%5E%7By%20%2B%20z%7D%20%5D%5BT%5E%7B-2y%7D%20%5D%20%5C%5CL%5E%7B0%7D%20M%5E%7B0%7D%20T%5E%7B-1%7D%20%3D%20%5BL%5E%7Bx%20%2B%20y%20-z%7D%5D%5BM%5E%7By%20%2B%20z%7D%20%5D%5BT%5E%7B-2y%7D%20%5D)
Equating powers on both sides, we have
x + y - z = 0 (1)
y + z = 0 (2)
-2y = -1 (3)
From (3), y = 1/2
From (2), z = -y = -1/2
Substituting y and z into (1), we have
x + y - z = 0
x + 1/2 - (-1/2) = 0
x + 1/2 + 1/2 = 0
x + 1 = 0
x = -1
So,
Disease that can be transmitted from bats to humans probably rabies.
Rabies is caused by a virus and can be transmitted by mammalian like dogs or bats. The symptoms can be fever, partial paralysis, anxiety, paranoia, hypersalivation(excessive drooling), hydrophobia(fear of water/drinking).
