Answer:
Cell deterioration
Explanation:
Once the cells first come in contact, they immediately create a cell shield that is composed of weaker cells, while the rest continue their work, the problem with this, is that their is a lack of cells to do work and the weaker cells are slowly dying and creating holes for the harmful chemicals to enter, as the cells deteriorate they clot together and create a lump in a final attempt, and it ends up creating deadly weight in the lungs.
Answer:
For the half of the radioisotopes of a certain kind to decay into more stable isotope, the amount of time required is called The Half Life.
Radiocarbon dating is typically used to date more recent objects like bones, cloth, wood, and plant fibers.
Sedimentary rocks cannot be accurately dated using isotope dating because this Rock type is formed through the sedimentation of different rocks and minerals fragment.
Using the principle of faunal succession, scientist can determine the age of rocks by the fossil flora and fauna embedded within them.
Explanation:
Carbon dating is a process which is done by the use of carbon 14 atom. It is a special type of atom which can easily help the scientist and expert to find out the age of the fossil of flora and fauna, rocks, animals, birds, etc.
Who Should Pay for the Consequences?
Explanation:
honeslty i think we should just eradicate human life as we kno it. the humans are basically a disease that is killing the earth and the only way to get rid of a disease is to kill it off. that is the only way to help the earth heal ans stop global warming and climate change yw
The sun is the source of energy for about all plant life.
Answer: Option E
Explanation:
Most of all poriferans/ sponges are suspension or filter feeders. Suspension feeders are organisms that each food materials which are suspended in their environment ie sea water, while filter feeders filter their food source from water by drawing water containing bacteria and organic matter in through their ostia(pores). Substrate feeders at organism that live in or on their food source.
Members of the poriferans do hava an ectoderm (epidermis) and an endoderm including a non-cellular late that is present in between the two layers.
No, they do not belong to the phylum cnidaria but porifera. Cnidarians including hydra, sex anemones, jellyfish etc and these have features that different from that of the sponges e.g the presence of nematocysts in cnidarians
Sponges can reproduce both sexually and asexually. Sexually by releasing larva fertilized in the sponge into water where they float around for some days and then proceed to adhere to a solid surface and begin their growth into adults. Asexually by budding
They are multicellular, lack tissues, are animals, lack organs and are asymmetrical. These are th distinguish features of poriferans
