Answer:
Los iones K + tienen un gran efecto en la apertura de los estomas.
Explicación:
Existe una gran relación entre la concentración de iones K + dentro de las células de guarda y la apertura de los estomas porque la concentración de iones de K + aumenta la concentración osmótica dentro de la guarda. El agua entra en las células de guarda por endosmosis, lo que aumenta la turgencia. La presión de turgencia de las células protectoras aumenta debido a esta endosmosis y las células protectoras permiten que los estomas se abran, por lo que podemos decir que los iones K + tienen un gran efecto sobre la apertura de los estomas.
When will an atom give up electrons?
When more than half of the outer energy level is filled
When the n=2 level is full
When less than half of the outer energy level is filled
When the outer energy level is full
Atoms give up electrons when less than half of the outer energy level is filled, forming positively charged ions. Noble gases with a full outer shell do not easily give up or accept electrons.
An atom will give up electrons when less than half of the outer energy level is filled. In chemistry, valence electrons are electrons in the outermost shell or energy level of an atom. Atoms tend to gain or lose electrons when the valence electron shells are not filled. When atoms lose their valence electrons, they become positively charged ions. An ion is a positively or negatively charged atom or group of atoms. For instance, sodium atoms give away one electron to form sodium ions with a positive charge because the outermost shell of sodium has only one electron, which is less than half the number needed to fill the shell entirely. When more than half of the outer energy level is filled, atoms are reluctant to give up their valence electrons, which is why noble gases do not form chemical bonds easily. When the outermost shell of an atom is full, it is stable, which is why noble gases do not give up or accept electrons quickly. Therefore, an atom will give up electrons when less than half of the outer energy level is filled.For more questions on electrons

how sclerenchyma tissues are important for plant though they are dead tissue ?
Answer:
Hey friend !!!
The cells of sclerencyma are without nucleus and protoplast....they are dead cells..
They provide mechanical support to organs of the plant body....
Hence they are important for plants....
Answer:
Sclerenchyma tissues are tissues that makes up parts of the plants that are hard. Like the nuts and covering seeds etc, These tissues have a hard thickness providing agent called lignin and lignin makes the cell wall too hard the sometimes the cell contains nothing. This cell mainly provides mechanical support to the plant
(3) (b) The mean concentration of red blood cells in an adult is 5.5 × 106 cells per mm3 1 mm3 = 0.000001 dm3 Calculate the mean number of red blood cells in 1 dm3 Give your answer in standard form.
Answer:
The correct answer is - 5.5*10^12 cells per dm^3
Explanation:
Given:
The mean concentration of red blood cells in an adult = 5.5 × 10^6
or = 5500 000
1 mm3 = 0.000001 dm^3
Solution:
Then, 1 dm^3 = 1000000 mm^3
(55000000 × 1000000) = 5500,000,000,000
= 5.5 × 10^12

Adapting to Life at Sea: Take a look at this article from Natural History Magazine. Explain the connection between sea snake's diet, the way in which they eliminate nitrogenous waste, and their need for freshwater. Then explain why this makes life (in at least one way) difficult for them in the ocean.
Answer:
They needs fresh water for drinking purpose.
Explanation:
The Sea snakes favorite food is fish and crustaceans. These sea snakes removes nitrogenous waste in the form of ammonia. They can live in salty water but needs fresh water for drinking purpose. This makes life difficult for sea snakes in the ocean because sea snakes needs fresh water to become hydrated and the sea water is salty which they can't drink so they depends on the rainfall for drinking purpose.
The sea snakes excrete their nitrogenous wastes via cloaca and some of it from the skin.
Sea snake
The snake excretes solid as well as liquid wastes from the cloaca but sometimes the flow of excreta gets disturbed due to change in the osmolarity between the environment and the body. The oceanic water is saline which is responsible for changing the osmolarity.This is making their survival difficult in the ocean.

How is pitch and intensity related?
Answer:
The results, when plotted as equal pitch contours, show the pitch of high tones increases with intensity, the pitch of low tones decreases with intensity, the point at which the effect reverses varies with intensity level.
Explanation: brainlest??
Answer:
the pitch of high tones increases with intensity, the pitch of low tones decreases with intensity, the point at which the effect reverses varies with intensity level.
Therefore intensity makes a tone lower or higher in pitch.
