Cellular junctions: by connecting cells to their neighbors
Receptors: allowing cells to respond to chemical messages
Homologous structures are similar bone structures in different organisms that are very similar. This should be your answer!
Have a great day- I hope this helps. :)
Angiosperms are commonly referred to as flowering plants, which have the highest division in Kingdom Plantae.
<h3>What are the characteristics of the Angiosperms?</h3>
- Angiosperms are flowering plants, which are characterized by the production of colorful flowers and fruits.
- Angiosperms undergo syngenesis, in which the ovary is converted to fruit and the ovule is converted into the seeds.
- Angiosperms are highly developed and vascular plants, which consist of xylem, phloem, and other specialized tissues.
- The angiosperms have developed root and stem systems. Stem provides adherence and support, while roots help in the absorption of nutrients from the soil.
Thus, angiosperms have the highest rank of division in the kingdom Plantae and bear several characteristic features like flowers, fruits, and roots.

Given what we know about phytoplankton biomass peaks in the polar region of the northern hemisphere, we can confirm that this occurs in the spring.
As the polar regions are tilted away from the sun, days there are short, sometimes these regions even enter month-long periods of darkness. Due to this, sunlight is not always strong enough to penetrate deep into the water.
In the Northern Hemisphere, the phytoplankton biomass peaks in the spring given that during this time the sun is high enough in the sky for sunlight to penetrate deep into the water and provide a food source for the plankton to thrive.
