Because if there are no animals we can't live, we purposely mix breeds maintaining more than one resource. <span>Maintaining biodiversity has a direct economic value to humans, as well as indirect economic value because our ecosystem is affected by any imbalances in the environment. For example, a lack of trees will mean we don't have enough oxygen to breath. A lack of fish will mean many animals that feed of sea creatures will die.</span>
Answer:
Hereditary factors do not combine but are passed on in the same form they were inherited.
Explanation:
Answer:
the natural process that warms the earth's surface is known as natural greenhouse.
Answer:
2.94 × 10²⁰ N/C
Explanation:
Given that:
The nucleus of "Lead-208 has 82 protons,
with a radius (r) 6.34×10-15 m, &
each electric charge has a value of 1.60218 × 10^-19 C
∴ The formula for calculating an electrical field at the surface of the nucleus is:
Substituting our values into the equation above, we have;
E =
E = 2.93870499×10²⁰ N/C
E ≅ 2.94 × 10²⁰ N/C
Answer:
Activation of dendritic autoreceptors produce hyperpolarisations. A drug that is an agonist at these autoreceptors would be classified as an antagonist for the synapse.
