Dinoflagellate is a type of neurotoxin which is found in the red-tide algae.

The answer is:

d. people can get paralytic shellfish poisoning during dinoflagellate blooms

Dinoflagellate algal blooms, during red-tide, release strong neurotoxins that can be ingested by shellfish and passed on to humans who eat the infected shellfish. The most significant public health problem that has been known to cause this harmful algae poisoning is: Amnesic Shellfish Poisoning (ASP).

What would you expect to happen to a plant as temperature and precipitation increases? Help ASAP!!!

zzz [600]

As temperature increases, the rate of transpiration rises as there is more evaporation.

As precipitation in the atmosphere rises, the rate of transpiration falls. Since precipitation means there is more water in the atmosphere as compared to inside the plant, less water is lost through osmosis.

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.

How does the foot of a bivalve differ from the foot of a cephalopod, or the foot of a snail? In what ways do these differences r

stira [4]

Answer:

Bivalve- Wedge shaped foot

Snail- Large and flat foot

Cephalopod- Foot is modified into siphon.

Explanation:

Molluscs are predominantly marine animals with a soft body,however,they are known to inhibit fresh water as well as terrestrial habitat.

They possess a *muscular foot*,which is used for *locomotion and anchorage*,they vary in shape and function depending on the type of mollusc.

MODIFICATION OF FOOT IN MOLLUSCS:

Bivalve- Foot is usually wedge shaped

Snail- Foot is large and flat

Cephalopod: Foot is modified int a siphon( a tube-like organ)

ADAPTATIONS OF FOOT IN MOLLUSCS

1)Bivalves have pointed retractable foot(wedge foot) that protrudes from the wheel and is adapted for *moving or burrowing*.

2)Snail have a mucus-laden muscular foot adaptation,that reflexes and contracts allowing movement(*crawling*) in water and terrestrial habitats

3)The foot of cephalopod is adapted for *moving* about by a kind of jet propulsion in water.
