Construct an argument about how the physical and biological components in the Chesapeake Bay ecosystem affect the crab populatio
Tamiku [17]

To make an argument about how environmental imbalance affects the ecosystem of the Chesapeake Bay, research on reliable sources on the topic is necessary.

<h3 /><h3>How is the Chesapeake Bay?</h3>

The bay corresponds to the largest ecosystem of estuaries in the USA, being a source of diverse types of habitat for wildlife, with more than 3,600 species of animals and plants.

An example of the environmental imbalance in the area is the commercial and recreational fishing of blue crab, whose population had a significant reduction in 2022.

Therefore, environmental factors and human exploration are responsible for generating such an imbalance, and the development of policies and actions to promote sustainability is essential.

How are the bryophytes and seedless vascular plants alike? Group of answer choices Plants in both groups have vascular tissue. I
dangina [55]

Answer:

In both groups, sperm swim from antheridia to archegonia

Explanation:

Bryophytes are the plant group that does not have a vascular system. These plants do not produce seeds. Ferns and horsetails are seedless vascular plants. These plants have vascular tissues (xylem and phloem) to serve in the conduction of water, minerals, and sugars from the one plant part to the other. But these plants do not produce seeds and hence, are seedless vascular plants.

Both bryophytes and the seedless vascular plants depend on water for fertilization. These plants release their male gametes in water which in turn move towards the female gamete. Sperms, the male gametes of these plants swim in the water to reach the female gamete.  

Antheridium is the male gametangium that serves as a site for the production of male gametes while archegonia are the female gametangia where the egg cell is produced.
