Answer:
Flat worms belong to Phylum- Platyhelminthes as they have flat body because they don't have any coelom in their body or called acoelomate
Explanation:
Coelom is called as the true body cavity that is found in Porifera and Cnidaria but when it comes to platyhelminthes, the coelom is not found and thus they have flat like structure and they are categorized under first triploblastic animals that is they contain 3 tissue layer which are found in higher animals (Ectoderm, Mesoderm and endoderm) also cephalization takes place in this parasitic group which indicates evolution towards higher, complex organisms.
What I think will happen as time goes by and right this second is that the earth is just going to fill and fill and fill with pollution
The question is incomplete as it misses the options which are:
Cancer cells do not exhibit density dependent inhibition
Cancer cells do not require growth factors
Cancer cells do not exhibit anchorage dependence
Cancer cells ignore typical cell cycle checkpoints
Answer:
The correct answer will be option- Cancer cells do not exhibit anchorage dependence
Explanation:
A cell becomes tumour forming cell or cancerous cell when the cell undergoes some mutation in the DNA which causes uncontrolled cell division without differentiation.
As a result of the mutation, these cancerous cells show various properties which are present in the normal cells nut absent in cancerous cells like the cancerous cells lack the anchorage dependence.
Anchorage dependence is the property of the cells or the group of cells in which the cells maintain their adherence to the other layer of cells to communicate with each other.
Thus, the cancerous cells lack the anchorage dependence
In multicellular plants and animals, however, meiosis is restricted to the germ cells, where it is key to sexual reproduction. Whereas somatic cells undergo mitosis to proliferate, the germ cells undergo meiosis to produce haploid gametes (the sperm and the egg).
