Mucous cells.

This cells primarily produce mucus and are frequently clustered into small glands found usually in the mucus membranes. They commonly lines the proximal and distal portion of the digestive tract. Large number of this cell can found in the mouth which moisten and keep the oral cavity moist. Stomach also have large number of mucous cells which help to protect the organ from the gastric juices it produce.

_____ splits water into 1/2 O2, H , and e- . A structure of a thylakoid. Letters from A to E indicate definite structures. Lette

Sauron [17]

The luminous reactions begin when light reaches photosystem II. The water molecules provide electrons to the photosystem, releasing oxygen and protons. The letter A represents photosystem II that splits water.

-----------

1. Luminous energy is trapped by chlorophyll in Photosystem II.

2. When the pigment molecules absorb light, electrons provided by water molecules get in a higher energy level.

3. The excited electrons go through the electron transport chain from Photosystem II to a less energetic level in photosystem I.

4. When the excited electrons leave photosystem II, they are replaced by new electrons extracted from the water molecules.

5. Luminous energy absorbed move the electrons from the photosystem I to another electron acceptor, from where they get transported again and used to produce NADPH molecules.

6. When electrons leave Photosystem I, they are replaced by new electrons coming from photosystem II.

7. When the water molecule breaks down, hydrogen ions remain in the thylakoid lumen, from where they are pumped to the stroma by the ATP synthase.

8. The released energy is used to produce ATP molecules.

9. Hydrogen ions go back from the stroma to the thylakoid compartment.

Long-term evolution between bats and moths can lead to coevolution. Coevolution occurs when two species evolve in response to th

Sonja [21]

In this case, the two species have coevolved by modifying behavioral traits (moths) and physiological traits (bats).

<h3>What is coevolution?</h3>

Coevolution is a particular type of evolution where a selective pressure imposed by one species serves to generate an adaptive change in another species and vice-versa.

Coevolution is fundamental in predator-prey relationships and leads to the emergence of new traits that are selected by natural selection.

In conclusion, the two species above have coevolved by modifying behavioral traits (moths) and physiological traits (bats).

Answer:

Neap tide - tide where there is the least difference between high and low water level
spring tide - tide where there is greatest difference between high and low water level
tidal bluges - two oceans bluges created on opposite sides of earth due to the moon gravitational pull and the ocean. resistance to the pull
