Answer:
group of interacting populations in a defined place and the nonliving factors that affect them
Explanation:
An ecosystem is a group of interacting populations in a defined place and the nonliving factors that affect them.
An ecosystem can also be a natural unit composed of living and nonliving components whose interactions result in a stable self-supporting system. Ecosystems are generally categorized as either aquatic or terrestrial.
I believe, from a population that is uniformly distributed through its habitat a biologist can infer that it has reached it's carrying capacity. Population distribution describes how the individuals are distributed, or spread through out their habitat. Population size and population measure are important measures of the population. When the population is uniformly distributed, it means that they are evenly spaced over the area they occupy, thus the individuals compete for a scarce environmental resources, such as water in a desert.
Answer:
Dissolve 47.025 grams of sucrose in enough water to produce 250 ml of solution.
Explanation:
You need to prepare 250. mL of a 0.550 M aqueous solution of sucrose, C12H22O11 (aq),
which is used frequently in biological experiments.
Based on your answer above, what is the value of x?
Solution:
A 0.550 M aqueous solution contains 0.550 mole of sucrose per liter of solution.
250 ml = 0.250 liter
Thus a 0.250 liter of a 0.550 M aqueous solution of sucrose contains 0.250 * 0.550 = 0.1375 mole of sucrose
Recall:
Mass = number of moles * mass of 1 mole
mass of 1 mole of C12H22O11
= 12(12) + 1(22) + 16(11)
= 144 + 22 + 176
= 342 grams
Mass = 0.1375 * 342 = 47.025 grams of sucrose.
Dissolve 47.025 grams of sucrose in enough water to produce 250 ml of solution.
Answer:
Emission
Explanation:
Semen contains sperm and the secretions released by the accessory sex glands such as seminal vesicle and prostate gland. Before the ejaculation of semen, the muscles of the epididymis, ductus deferens, seminal vesicles, ejaculatory ducts, and prostate gland exhibit peristalsis. This results in the release of the secretions from the accessory glands and reproductive duct into the urethra. Since semen is present in the urethra, a small volume of semen is discharged even before ejaculation during emission.
