select the incorrect association amoeboid cell - digestion, collar cell - water current, epidermal cell - covering, spicule cell
Morgarella [4.7K]

Spicules is the skeletal structures which occur in most sponges. They provide structural support, as well as determent against predators. Large spicules, visible to the bare eye are called as megascleres, while smaller, microscopic ones are called as microscleres. Spicule cell - reproduction is the incorrect option.

amoeboid cell - digestion

<h3></h3><h3>What is amoeboid cell?</h3>

Amoeboid cells are the that have capacity to change shape due to the parts of the skeleton of the cell called cytoskeleton and plasma-gel which changes the consistency of the cell's cytoplasm. Amoeboid cells use a pseudopodia, or false foot, to move forward. They carry-out phagocytosis, which is to eat or ingest other cells.

collar cell - water current

The collar cells serve two functions. Firstly, they beat their flagella back and forth to force water through the sponge. The water brings in nutrients and oxygen, while it carries out waste and carbon dioxide. Second, the sticky collars of the collar cells pick up tiny bits of food brought in with the water.

epidermal cell - covering.

The epidermis and its waxy cuticle provide a protective barrier against mechanical injury, water loss, and infection.

Temka [501]

There have be found some fossils of ancient remains over the years. What the fossils from Atapuerca revealed about the hominins living in Europe at this time is below:

  • The Skull is known to show Interbreeding that took place with neandertals and their relatively healthy population.

  • The Fragment shows that there was a possibility of cannibalism in that area.

It shows that possible cannibalism took place as there were Cutmarks on various hominin bones found at Atapuerca mirror.

The relatively healthy population was found out through the study of the dentition of the Atapuerca hominins by anthropologists. It gave them a view into their diet and overall health.

The interbreeding with the Neandertals was shown through the Nuclear DNA that was gotten from bones and teeth of bones found at Sima de los Huesos

A drought causes a wildfire which destroys a forest. Which Earth systems interact during this process? (1 point) Select one: a.
Ne4ueva [31]

<u>Answer:</u>

<em>It is the biosphere and hydrosphere that interact when a drought causes a wildfire that destroys a forest. </em>

<u>Explanation:</u>

Hydrosphere consists of all the water bodies of earth like oceans, seas, rivers, lakes etc.  a drought occurs due to scarcity of water which affects the hydrosphere. The scarcity of water causes plants and trees to dry up and become more prone to catching fire

Biosphere includes all the living organisms of the earth. It includes plants, trees, birds, insects, animals etc. A drought dries up a whole area and a small fire that starts up somewhere in  a forest would then engulf the whole forest.
