<span>The research shows that the relationship between estrogen and verbal tasks is negative while it is positively correlated with spatial tasks. This correlation shows that, like in other animal studies, there could be some sort of organizing of the brain that goes on related to the level of sex hormones in the body.</span>
The right answer are all the three of them (1, 2 and 3).
Let's compare between a normal cell culture and a cancer cell culture:
- Normal or defined cultures: the cells only multiply during a limited number of degenerations (30 to 50 subcultures) then die: their life and their death is programmed. We then observe a decrease in their rate of proliferation, phase of senescence.
- Continuous culture or transformed or immortal lineages. The multiplication speed does not decrease (reproduction without limits, non-stop), which allows an indefinite number of subculture. The cells constituting these cultures lose the contact inhibition and grow in clusters or multilayer (multiple layers).
Answer:
The correct is B Hormones are chemical signals between cells transported in blood or hemolymph.
Explanation:
Hormones are called chemical messenger of the cell because they transmit chemical information from one cell to the target cell and regulating the functioning of that target cell by activating specific proteins related to the functioning of that target cell.
Hormone is secreted from its source gland such as Pituitarygland, thyroid gland,adrenal gland.After being secreted hormones are transported via the blood stream to the target cell and binds to receptor of that target cell thus allowing the target cell to exert its biological function.
Livor mortis is the <span>condition in the body happens as the blood stops pumping through the body and settles in the parts of the body lowest to the ground.

Answer:
Bacteria,fungi and protists are all heterotrophs, taking their food source from something else. Fungus can also be used as food or as a pest, poisoning and killing plants in your yard (watermole- Potatoe famine). Protists: Protists have eukaryotic cells,and can be heterotropic but can be autotropic.
