Explanation:
hope this helps
Answer: when water moves from an area of LOW solute concentration (low osmolarity) to an area of HIGH solute concentration (high osmolarity) through a semipermeable membrane.
Explanation: In biology, osmosis is the movement of water molecules from a solution with a high concentration of water molecules to a solution with a lower concentration of water molecules, through a cell's partially permeable membrane.

Describe the unique feedback mechanisms of estrogen in the feedback loop of the
ovary and pituitary. Make sure to include FSH and LH in the explanation.
The unique feedback mechanisms of estrogen in the feedback loop of the ovary and pituitary is to enhance the secretion of GnRH and gonadotropins which lead to ovulation.
How does estrogen play a role in a feedback mechanism?The positive feedback effect of estrogen is the mechanism in which the GnRH cells of the brain and the pituitary gonadotrophs produce in the secretion of GnRH and gonadotropins, this will lead to ovulation. Estrogens regulate the secretion of Luteinizing hormone by controlling the secretion of GnRH from the region of hypothalamus as well as the secretion of GnRH that stimulates both tonic Luteinizing hormone secretion and the Luteinizing hormone.
So we can conclude that the unique feedback mechanisms of estrogen in the feedback loop of the ovary and pituitary is to enhance the secretion of GnRH and gonadotropins which lead to ovulation.

Suppose the index’s fossil in the diagram has an absolute age of 454 million years in your own words,explain how scientists could estimate the ages of the other fossils in the diagram based on this information.
Geologists frequently utilize radiometric dating techniques to analyze the age of fossils, which are based on the natural radioactive decay of specific elements like potassium and carbon.
Radiocarbon: 1–70,000 yearsUranium-Lead: 10,000–billion yearsAbsolute dating and relative dating are the two basic techniques for estimating the age of a fossil. By comparing a fossil with related rocks and fossils from same time period, relative dating is performed to determine the approximate age of the fossil. This is known as relative dating. Absolute dating can be done by measuring the decay of isotopes within the fossil or rocks, to estimate the exact age of a fossil. The radioactive materials present in nearby rocks and fossils are used for absolute dating. These radioactive materials essentially function as a geological clock, revealing a fossil's precise age.Isotopes typically "degrade" with time at a predictable, steady rate. Hence, the age of the specimen can be calculated by comparing the amount of the original parent isotope to the amount of the daughter isotope it decays into.Therefore, relative dating can be used to estimate the ages of other fossils.

1) Cetacea gives live birth to a very small number of offspring at one time and invest a great
amount of energy in parenting. Most fish, however, reproduce hundreds at one time and spend
very little time in parenting. Discuss the advantages and disadvantages of both methods.
There are two condition: -
1. Less offspring, and more parenting
2. More offspring and less parenting
Less children and more parenting have the advantage of requiring less energy for reproduction and more for parenting, which eliminates the possibility of infant death. The drawback is that this results in a relatively small number of progeny, who may be eliminated by the environment, enemies, or predators, causing disruption in population.
The benefit of having more children and doing less parenting is that there will be a huge amount of children generated who are capable of reproducing, which will ultimately lead to population expansion. The drawback of this situation is that there is no guarantee of survival because of the possibility of encountering predators, natural disasters, or other challenges.

Answer: C, capillary action.
Explanation:
A straw works because when you suck the air out of the straw, it creates a vacuum. This causes a decrease in air pressure on the inside of the straw. Since the atmospheric pressure is greater on the outside of the straw, liquid is forced into and up the straw and into your mouth.

D. Draw Conclusion
The correct answer is B. Form a hypothesis.
Since at least the 17th century, the scientific method has guided the growth of science. It is an empirical approach to information acquisition (with notable practitioners in previous centuries). Given that cognitive presumptions might skew how one understands the observation, it requires careful observation and the use of strong skepticism regarding what is observed. It entails developing hypotheses through induction based on these observations, statistically evaluating deductions taken from the hypotheses using experimental data, and then modifying (or removing) the hypotheses depending on the experimental results. These are scientific method principles, as opposed to a predetermined set of processes that apply to all scientific endeavors. An educated prediction as to what will occur throughout your experiment serves as the hypothesis.Variables will be used in your experiment.Therefore, the correct answer is B.

45. The solubility value of table salt at 251C is 37.7 grams per 100 milliliters of water. If you add 60 grams of salt to
200 milliliters of water at 251C, what do you expect will happen? (1 point)
O The solution becomes saturated.
The solution becomes supersaturated.
Only 37.7 grams of salt dissolve.
The salt dissolves.
Answer:
The salt Dissolves.
Explanation:
See the differences between saturated, unsaturated and super saturated is that
a) Unsaturated is that the amount of solute still hasn't reached its max
b) saturated is that the amount of solute has reached its max
C) Super saturated is that the amound exceeded the maximum amount
From the givens, I can see that it requires 37.7 grams per 100 millimeters
it means it requires 75.4 gram of Salt to make the solution SATURATED per 200 millimeters.
Any amount below this one, the 75.4 gram, will make it just dissolves (Unsaturated). Any amount more than the one we've said so far would be supersaturated.
