Answer:
The right answer is 1 and 4
Explanation:
A hormone is a biologically active chemical substance, synthesized by a glandular cell secreted into the internal environment where it circulates, acting remotely and by blood on receptors specific to a target cell. It transmits a message in chemical form and therefore plays a role of messenger in the body.
The emitting organ thus acts at a distance on all of the target organs of the organism or of neighboring organisms of the same species, or even of symbiotic organisms whose receptors are activated in contact with specific hormones (lasting interactions).
Answer:
(3) 4 cm' and 2.0 g/cm3
Explanation:
Given:
volume= V= 8 cm³
mass= m= 16 g
The density is the mass per volume of a substance, so the density of the rock is:
density= d= 16 g/8 cm³= 2 g/cm³
When we cut the rock in half, we have a half volume and a half mass:
V= 8 cm³/2= 4 cm³
m= 16 g/2= 8 g
But the density is not altered because it is an intrisic property - it does not change with the amount of subtance. Thus, the density of a half rock is:
d = m/V= 8 g/4 cm³= 2 g/cm³
Answer:
Amoeba reproduces by the common asexual reproduction method called binary fission. After replicating its genetic material through mitotic division, the cell divides into two equal sized daughter cells.
