Answer: Chordates

Explanation:  

Pharyngeal slits are found in the embryos of the chordates. Pharyngeal slits are the filter organs present in the chordates. These are the openings in the pharynx near the mouth. The function is to allow the movement of water inside the mouth and the unwanted or excess water is removed by the pharyngeal slits. These slits also aid in respiration of the aquatic chordate animals.

Using the following biomass data determine which groups is most likely to represent the producers in an area
Vsevolod [243]

Answer:

The correct answer would be group D- 809 kg.

It can be explained with the help of pyramid of biomass.

Pyramid of biomass represents biomass or the amount of organic or living matter present at each trophic level in an ecosystem.

The amount of organic matter is usually expressed in grams per meter square (g/m²).

There are usually four trophic levels in the pyramid of biomass: primary producers, primary consumers, secondary consumers, and tertiary consumers.

Usually, the biomass decreases as we go up the trophical levels specially in  terrestrial ecosystem. Inverted pyramid can be observed in case of aquatic ecosystem (biomass of phytoplanktons is less than that of herbivores).

Here, maximum biomass (809 kg) belongs to the group D and hence, it would belong to primary producers.

The section of the cell membrane illustrates one method of cellular transport. Consider steps A, B and C. What transport mechani
andrezito [222]
The model attached represents facilitated transport, which is answer choice D. In the model, there are protein channels, which allow molecules to pass through them if they're too large to fit through the aquaporins (making diffusion an incorrect answer.) We can eliminate active transport since ATP isn't used to control transport, and we can eliminate endocytosis as it is a form of active transport. The remaining answer would be facilitated transport, which is a form of passive transport. Hope this helps! :)

The plane that separated the body into superior and inferior portions is a sagittal plane.
dybincka [34]

Answer: False  

Explanation:

The saggital plane divides the body into two halves based on the fact that the body is segmented into left and right planes.

The plane may be away or at can lie at the center of the body and it splits the body into parts. It  may be far or close to the midline of the body. It may also split the body into two unequal parts.

The term saggital is coined by Gerard Cremona.
