The fact that choanoflagellates and collar cells of sponges resemble each other supports the inference that ________. Group of a

antoniya [11.8K]

Answer:

choanoflagellates and sponges are sister groups

Explanation:

The choanoflagellates are small unicellular organisms belonging to the Protista kingdom. These microorganisms are collared flagellates morphologically similar to the choanocyte cells of animal sponges, which have a central flagellum surrounded by a collar of microvilli. In consequence, it has been suggested that choanoflagellates may represent the closest living relatives of primitive metazoans (i.e., they are sister groups to sponges). This hypothesis has recently been supported by both molecular phylogenetic and comparative genomic analyses.

What was the average of diameters (cm) for the Willapa Bay urchins sampled before the hunt? (Type just the number rounded to the

Otrada [13]

Answer:

See Explanation

Explanation:

The question is incomplete as the diameters of the Willapa Bay urchins were not given.

However, I'll give a general way to solve this problem.

Average is calculated using:

$Average = \frac{\sum x}{n}$

i.e. Sum of all diameters divided by the number of bay urchins.

The diameter of urchins is usually between 6cm to 12cm; So, I will assume the following diameters for 10 urchins.

10cm, 8cm, 10cm, 7cm, 9cm, 10cm, 6cm, 10cm,8cm, 8cm

Using the above data, the average is:

$Average= \frac{10+8+10+7+9+10+6+10+8+8}{10}$

$Average= \frac{86}{10}$

$Average= 8.6$
