Plasma estrogen levels reach their peak at the end of the luteal phase of the ovarian cycle.
a. True
b. False
Answer:
Plasma estrogen levels reach their peak at the end of the luteal phase of the ovarian cycle.
a. True
Explanation:
A woman's estrogen levels become highest towards the end of her ovulation. At this point, the woman is naturally prepared for a possible pregnancy. The occurrence of the highest estrogen levels coincides with the luteal phase, a stage of a woman's menstrual cycle, which occurs after ovulation (or the release of eggs from the ovaries), and before the start of the normal period. This luteal phase has been observed to be within 14 days for all women. By the end of the luteal phase, the corpus luteum function declines.

would occur if we were suddenly thrown back into the “Dark ages” with no use of technology
So there are a lot of people who say that the Dark Ages, lasting about 1,000 years, set humans back technologically. However, some say that since the Dark Ages really only affected Western Europe, and not the Middle East or Asia, it wouldn't make a difference.
If there had been no "Dark Ages" there would have been no Renaissance. Historians actually argue about when Renaissance started, and the answer is than it is not possible to pinpoint a date. The Crusade did more to bring the eastern world to western Europe than they did to divide.

When someone says they have a "fast" metabolism, they are referring to the fact that they are able to efficiently
break down complex molecules at a higher rate than the average person.
Which of the following answer choices best describes someone with a "slow" metabolism?
Choose 1 answers
Low rate of catabolism
Low rate of anabolism
High rate of catabolism
Equal rates of catabolism and anabolism
Answer:
CORRECT (SELECTED)
Low rate of catabolism
Explanation:
Someone with a "slow" metabolism would have a low catabolic rate because their ability to break down complex molecules occurs at a slower, less efficient rate than someone with a "fast" metabolism.

A. volume increases and density decreases
Explanation:
I got a 5 on mastery test thanks to some comments on original answer
Based on the graph, the density of water decreases as the temperature decreases from 4°C to 0°C. Therefore, a fixed mass of water will have a higher volume at 0°C than at 4°C.
What is the density-temperature relationship?The density of a substance is defined as its mass per unit volume. In the case of water, the density varies with temperature, as shown in the graph. At 4°C, the density of water is about 1000 kg/[tex]m^3[/tex]. As the water is cooled, its density decreases, reaching a minimum of about 999.87 kg/[tex]m^3[/tex] at 3.98°C (this is the temperature at which water is most dense). As the water is cooled further, the density increases again, but it remains lower than it was at 4°C. The reason for this behavior can be explained by the way water molecules behave as they are cooled. At higher temperatures, the water molecules have more kinetic energy and are more spread out, resulting in a larger volume and lower density.
Hence, the density of water decreases as the temperature decreases from 4°C to 0°C. Therefore, a fixed mass of water will have a higher volume at 0°C than at 4°C.

Your student is trying to create a "Gene X" knockout mouse by introducing a recombinant construct into embryonic stem (ES) cells, selecting transformants, and introducing the transformed cells into mouse blastocysts. He designed his construct as follows: NeoR region of homology to Gene X---HSV tk--- region of homology to Gene X where Neo is the neomycin-resistance gene and HSV tk is the Herpes Simplex virus thymidine kinase gene. He transforms the ES cells and exposes them to G418 and ganciclovir. Explain to your student why he failed to recover transformed ES cells. Choose the two correct statements. a. His construct incorporated into the mouse DNA by illegitimate recombination. These cells would be sensitive to ganciclovir and neomycin, and would die.
b. His construct incorporated into the mouse DNA by illegitimate recombination. These cells would be resistant to ganciclovir, but sensitive to neomycin, and would die.
c. His construct incorporated into the mouse DNA by homologous recombination. These cells would be sensitive to ganciclovir, but resistant to neomycin, and would die.
d. His construct incorporated into the mouse DNA by homologous recombination. These cells would be sensitive to neomycin and ganciclovir, and would die.
e. His construct incorporated into the mouse DNA by homologous recombination. These cells would be sensitive to neomycin, but resistant to ganciclovir, and would die.

How do mutations happen?
Answer:
HOPE THIS HELPS
Explanation:
A mutation is a change in a DNA sequence. Mutations can result from DNA copying mistakes made during cell division, exposure to ionizing radiation, exposure to chemicals called mutagens, or infection by viruses.

Which of the following best explains the phrase "survival of the fittest" in terms of evolution by natural selection? (1 point)
O Only individuals that have the most mates will survive with limited resources
The individuals that are the healthiest will always get more resources and survive better
O The individuals that survive better and reproduce more often will pass their traits on more often.
The strongest and fastest individuals will always survive and reproduce more often
Answer:
C
Explanation:
This is because the favorable traits will typically be present within the surviving animals leading them to be able to survive long enough and pass down more favorable traits.
Hope this helps!
The sentence that best explains the phrase "survival of the fittest" the individuals that are the healthiest will always get more resources and survive better.
Evolution by Natural selectionThe theory of evolution was proposed by the scientist, Charles Darwin. He proposed that species can change over time, that new species come from pre-existing species, and that all species share a common ancestor.
Natural selection according to Charles Darwin was based on the fact that traits where inheritable. From his experiment, he concluded that:
some individuals will have inherited traits that help them survive and reproduce,organisms with these traits leave more offspring, the traits will tend to become more common in the next generation.These organisms with these helpful traits will become better adapted to it's environment.Therefore, the individuals that are the healthiest will always get more resources and survive better.

Which type of cell division causes a puppy to grow into an adult dog?
meiosis
mitosis
eukaryotic
O homeostasis
Mitosis is the kind of cell division which allows a puppy to develop into an adult dog. So, the correct option is B.
What is Mitosis?In eukaryotic cells, a process called mitosis produces two daughter cells, each of which has the same amount of chromosomes as the parent cell. Multicellular organisms, like dogs, go through a process called mitosis during which cells divide and differentiate into different cell types.
The process of meiosis, on the other hand, produces gametes with half as many chromosomes as the parent cell and is only able to occur in specialised cells, such as the ones involved in sexual reproduction. Contrarily, homeostasis has nothing to do with cell division and instead refers to the preservation of a constant internal environment within an organism.
Therefore, the correct option is B.

Approximately 55%of an adult female body weight is water if a woman body contains 38 kg of water what is the woman's total weight
Answer: 69kg
Explanation:
Let the total weight of the woman be represented by x. Based on the information given, we can derive an equation which will be:
55% of x = 38kg
55/100 × x = 38kg
0.55 × x = 38kg
0.55x = 38kg
Divide through by 0.55
x = 38kg/0.55
x = 69.09099
x = 69kg
Therefore, the woman's total weight is 69kg.
