Answer:
many breast cancers have no obvious symptoms at all. When there are no symptoms, breast cancer can be found through a screening mammogram. The most important thing is to bring any unusual signs to your doctor's attention, and to talk to your doctor about a breast screening plan that is appropriate for you
Explanation:
An embryo with meroblastic cleavage, extraembryonic membranes, and a primitive streak must be that of a option(c)i.e, bird.
Mesoderm is produced by the primitive streak, and it eventually becomes mesenchyme (embryonic connective tissue). Around growing organs, mesenchyme develops into a packing tissue before becoming connective tissues and muscles. With birds, we start to witness the embryos develop in a meroblastic manner, with a lot more yolk than usual. Cell mobility is also unusual because the cells in birds lie more in sheets than in balls.
A longitudinal thickening of cells along the blastoderm of large-yolked eggs forms the primitive streak during ingression, through which potential chordamesoderm and mesoderm cells move inward. Cells of the hypoblast are replaced by endodermal cells. Through ingression, the embryo develops longer and fills more of the region pellucida, lengthening the original stripe over the surface of the yolk. Following gastrulation, the neural tube and its supporting components are formed during the process of neurulation.

Answer:
Chromosomes
Explanation:
Multicellular organism are organisms that have more than one cells in their body. However, from the very beginning of every living organism including multicellular organisms, only ONE cell is required. In the case of multicellular organisms, this one cell undergoes division by mitosis to form other cells.
Since the cells divide by mitosis i.e 1 forms 2, 2 forms 4 etc.,. each of the cells are genetically identical to one another. Hence, this means that all the cells will contain the same number of chromosomes in their genome. For example, a dog as a multicellular organism has cells that emanate from one cell. If that one cell contain 39 chromosomes, all cells in the dog will also contain 39 chromosomes.
The correct answer in the space provided is bodily changes. It is because when a clinician is in the field of thanatology, it is likely that he or she is focusing on the aspects of death in which he or she investigates forensically, changes in the body or the post mortem period that is associated to death.
Among others, both plants and animals need oxygen and water. They also both need space and air.
