How does the sticky tip of the pistil help a plant reproduce

Biology
1 answer:
Elanso [62]3 years ago
5 0
The pistil is the female reproductory organ of a flower that is responsible for capturing pollen, the male counterpart of the sexual reproduction with flowers, and potentially produce seeds. The fact that this pistil is sticky allows the pollen to actually adhere to this organ and migrate to its interior and sexual reproduction to happen.

What part of henry’s cochlea may have damaged hair cells? What part of henry’s cochlea may have functional hair cells?
mamaluj [8]

The henry's may have damaged and functional hair cells of cochlea in organ of corti.

Hearing and the Cochlea:

  • Sound waves that enter the ear go through the external auditory canal before they strike the eardrum and cause it to vibrate.
  • The incus receives sound vibrations from the malleus, also called "hammer," which is linked to the eardrum, and sends them on to the stapes.
  • The stapes is a framework that moves the oval window in and out. This motion is received by the cochlea, a fluid-filled snail-like structure that houses the organ of Corti, the hearing organ.
  • Small hair cells make up the lining of the cochlea. These cells convert vibrations into electrical impulses that sensory nerves then transmit to the brain. the Corti organ, which has four rows of hair cells. On the left, there is an inner row, and on the right, there are three outside rows.
  • The stapes first sways against the oblong glass. This causes sound waves to travel into the cochlear fluid and move the organ of Corti.
  • Lower frequency sound resonates with fibers towards the cochlea's upper end. Higher frequencies elicit a response from those near the oval window.

what would happen to an enzyme if the temperature and pH changed significantly beyond the enzyme`s optimum level?
allochka39001 [22]
<span>If the PH and temperature changed significantly beyond the enzyme optimum level it will become denatured and then the enzyme would not work.
The Enzyme is a biological catalyst which speeds up a reaction. The Enzyme has molecules which act upon as substrates and then it converts those substrates into different molecules which are called products.
The study of the enzyme is known as enzymology, and they are well known to catalyze more than 5,000 biochemical reaction types.</span>

Select the correct answer from each drop-down menu.
aksik [14]

Answer:

Just before the cat drops, it was stationery. Therefore it has energy of position called  potential energy.As it drops, the Gravitational potential energy is converted to Kinetic Energy,The conversion mid- air is P.E to K.E to P.E to K.E to P.E to K.E, until it touches the ground. As it touches the  ground all the energy is converted to P.E energy of position.

As it runs after mouse the P.E is converted back to Kinetic , energy of motion. As it feeds on the mouse , the chemical energy obtained  as protein from mouse meat.This is later converted back to Mechanical energy as (kinetic and Potential  energy)   in the cat.
