A sponge actually feeds by
a. acting as a net in a current that sweeps food particles through it.
b. squeezing the spongocoel cavity and sucking debris in and out through the osculum.
c. the beating of the flagella of collar cells, forming a current; food is absorbed by collar cells.
d. the beating collar cells form a current from osculum to pores; the food is engulfed by amoebocytes in the central cavity of the sponge.
e. water the moves gently through the sponge and the amoebocytes that engulf passing food.
Answer:
c. the beating of the flagella of collar cells, forming a current; food is absorbed by collar cells.
Explanation:
Sponges contains the unique feeding system that should be with the animals. Rather of mouths they have the tiny pores that we called as the ostia displayed on the outer walls via water is drawn. Here cells in the sponge walls strainer the food from the water because the water is pumped via the body and the little mouth
So as per the given options, the option c is correct as the collar cells would create the current and the food should be absorbed by the collar cells

Which of the following options is true for aerobic and anaerobic respiration? * The answer is between C and D
Answer:
C
Explanation:
Can I get Brainliest? plz?
Answer:
C is the correct answer.
Explanation:
This is because aerobic does in fact release large amounts of energy as opposed to anaerobic, which releases very small amounts of energy. It isn't D because in anaerobic, the products are organic AND inorganic.

Mechanical weathering is more rapid in warm, wet climates.
true or false?
Answer:
false
Explanation:
In cold climates, water freezes and expands as a result, breaking rocks with sheer force. The smaller rocks or sediments are washed away by erosion.
During the warm wet season, rocks expand and contract. As a result, the rocks are weakened and eventually fracture.
Note that the rate of weathering depends on the types of rock and temperature change. Rocks in tropical climates experience the highest rate of weathering because of the combination of high heat and heavy rainfall.

Directions: Consider a pedigree that is tracking an autosomal recessive trait, where two recessive alleles (tt) result
in the inability to taste a chemical known as PTC. The ability to taste PTC is determined by the presence of a
dominant allele (T). Complete the missing boxes in the chart. The first row has been done for you as an example!

What are the 3 major organs of excretion and what do they excrete?
Answer:
Skin, Kidneys, And Lungs
Explanation:
Excretion is the removal of toxic materials, waste products of metabolism and excess substances from organisms. Egestion is the passing out of undigested food as faeces, through the anus. Three major organs of excretion are the skin, kidneys and lungs. Sweat glands in the skin produce sweat.

what is cloning in plants? Please don't post inappropriate answers.
Answer:
hope it helps..
Explanation:
This is a process of taking part of a healthy plant, replanting it, and having it grow. Since cloning is a form of asexual plant reproduction–meaning only one 'set' of DNA–the resulting clones are an exact replica of the parent plant.

Which is a density dependent factor?
This sea anemone and this ctenophora both have tentacles, which are body structures that help them catch food. However, sea anemone tentacles are short and can sting, while ctenophore tentacles are long for grabbing and cannot sting. What most likely explains why both species have tentacles and why the tentacles are different
Answer: Sea anemone and ctenophore both inherited tentacles from a shared ancestor population, but this population separated into different environments. In each environment, different types of tentacles evolved, which helped the populations survive.
Explanation:
most likely explains why both species have tentacles and why the tentacles are different is because sea anemone and ctenophore both inherited tentacles from a shared ancestor,
Then, this population separated into different environments and there was tye evolvement of different types of tentacles evolved, which therefore helped the populations survive.

To be perfectly honest, I'm not sure what problem 32 is asking. It seems like there's set up to a question, but the actual question itself is missing.
=============================================
For problem 33, we divide the tape's distance by its time. I'm assuming that problem 33 is using the set up info from problem 32.
Recall that
distance = rate*time
we can rearrange things to say
rate = distance/time
So that's why we divide distance over time. The tape's length is effectively the distance, more or less. Imagine that one marker on the tape travels from one end of the reel to the other. It would have to travel the length of the tape when the full tape duration elapses.
----------
So,
rate = distance/time
rate = (260 meters)/(180 seconds)
rate = (260/180) meters per second
rate = 1.44 meters per second, which is approximate
I'm rounding to 3 sig figs.
