Answer:hydrogen atomic no and mass no is 1. In hydrogen there is one electron ,one proton and zero neutron.
Explanation:
Neutron is zero because neutron
Nnumber =atomic no - mass no so 1-1=0.
Answer:
Protists are eukaryotic organisms that cannot be classified as a plant, animal, or fungus. They are mostly unicellular, but some, like algae, are multicellular. ... Protists can be heterotrophic, which means they obtain the energy they need to live by consuming other organisms.

<h2>Xylem;phloem and cork</h2>
Explanation:
Wood is mainly known as secondary xylem found in trees
- Xylem is basically the vascular tissue which is responsible for the conduction of water and nutrients from the roots to shoots and leaves
- Secondary xylem is formed from secondary growth and is associated with lateral growth and grows from the vascular cambium
- Its cell walls are thickened by deposition of lignin which provides mechanical support to plants and consists of tracheids and vessels that are shorter and wider
- In large woody plants secondary xylem get differentiated into heartwood and sapwood
Bark is essentially made of phloem and cork
- Bark sole purpose is to provide protection to trees
- The inner bark is produced by vascular cambium which consists of secondary phloem whose innermost layer transports food from the leaves to rest of the plant
- The outer bark is a dead tissue which is the product of cork cambium
The similarities between the low-light seedlings and moderate-light seedlings are the amount of chlorophyll until 12 hours and the differences suddenly increase after this period.
<h3>What is photosynthesis rate?</h3>
The photosynthesis rate is the amount of photosynthetic products (i.e., glucose) that generates by a plant in a given unit of time, which depends on the amount of chlorophyll.
In this case, low-light seedlings and moderate-light seedlings produce amount of chlorophyll at a similar rate until 12 hours, while the maximized value for moderate-light seedlings and low-light seedlings is 48 hours.
In conclusion, the similarities between the low-light seedlings and moderate-light seedlings are the amount of chlorophyll until 12 hours and the differences suddenly increase after this period.
