Keratin is an intracellular fibrous protein that gives hair, nails, and skin their hardness, strength, and water-resistant properties. The keratinocytes in the stratum corneum are dead and regularly slough away, being replaced by cells from the deeper layers
Hope this helped!
Good luck :p

The amount of oxygen produced can be quantified in order to determine the rate of photosynthesis. Elodea leaves are divided into little pieces, and the cut ends are put into the funnel's stem.
<h3>What did Elodea's bubbles in this experiment represent?</h3>
The bubbles that you observe rising from an elodea cutting's leaves are actually a result of the photosynthesis process. In some types of algae and in plants, photosynthesis takes place. In the process, light energy is changed into a sort of chemical energy that is then stored as sugar.
<h3>What substance did we use to examine whether photosynthesis existed in Elodea?</h3>
To test whether photosynthesis and/or other processes are occurring, you will conduct experiments using the dye Phenol Red in this exercise. In Elodea plants, cellular respiration is taking place. The experiments look into how light affects these processes.

Answer:
Carbon.
Explanation: It is the only element that makes up every living thing.
Finger
contusion can be characterized by bruising of finger, where there is swelling
and bleeding under the skin but no broken bones.
1. Diagnosis and Management:-
Contusion of finger is diagnosed by the symptoms such as pain, swelling,
discoloration, tenderness and difficulty in movement. Sometimes numbness is
associated as swelling compresses the nerves in that region.X-ray (If required
CT scan0 can be done to confirm the diagnosis and rule out fractures and other
serious forms of injuries.
Depending upon the severity,
treatment is decided. The contusion is managed with an aim to reduce pain,
swelling and restore the movement. The options so as to treat the contusion,
based on its severity are as follows
a. Applying Icepacks and
keeping the finger propped up above the heart level.
b. Splinting and taping
c. Physiotherapy
d. Ultrasound therapy
e. Surgical treatment is
required in case of torn ligaments.
These options of treatment
are accompanied with over the counter pain killers and anti inflammatory drugs
