Answer:
I'm really sorry I can't answer your other questions but protons are stuck to the neutron in the center and they are a positive charge. Neutrons fly around the outside and have a negetive charge. The neutron is in the very center and has no charge whatsoever.
Explanation:
I really hope I helped!
<span>B. organ systems, organs, tissues, cells
Organ systems are the most complex in this grouping, they are made up of multiple organs, tissues and cells all working together with other organ systems to keep an organism alive. Examples of organ systems are the digestive system, respiratory system, nervous system. Organs are groups of tissues and cells working together with a main purpose. Examples of organs are heart (pumps blood), brain (controls the body), stomach (digests food). Tissues are groups of cells working together as a whole such as cardiac tissue, adipose tissue and blood. Cells are the smallest unit of life, in groups they form tissues and organs. Cells of the body include neurons, blood cells, skin cells, and fat cells.</span>
No because of the whole population was identical they would not have genders and would not be able to reproduce. Reproduction is essential to evolution
Answer:
Well, on one hand, this is a good thing as negative effects of the high demand for wood such as deforestation can be minimised. This will also sustain the supply of wood for several applications. However, there could be negative consequences of propagating such genetically-modified trees, which were not stated or are not yet known. For instance, the trees could be extreme soil nutrient consumers—depleting soil nutrients at a faster rate than they can be replenished and rendering such soil infertile in a short period.
1) variation in traits.
population of beetles: equal brown and green numbers in population.
2) differential reproduction.
Natural habitat is in trees. Green leaves hide green beetles.
The brown beetles are noticed by birds in the area.
Birds eat brown beetles.
More green beetles survive than brown beetles
3) heredity
Green beetles reproduce in greater numbers than brown beetles
4) end result
Beetle population changes from brown and green to mostly green beetles.
