Plasma estrogen levels reach their peak at the end of the luteal phase of the ovarian cycle.
a. True
b. False
Answers
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.

Which type of cell division causes a puppy to grow into an adult dog?
meiosis
mitosis
eukaryotic
O homeostasis
Answers
Meiosis is for sexual reproduction and for producing offspring, whereas mitosis is the cell division for cell reproduction so it has to be mitosis as it is the cause of cell growth, allowing the puppy to grow into an adult dog
It wouldn't be eukaryotic or homeostasis since they're not types of cell division.
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.

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.

would occur if we were suddenly thrown back into the “Dark ages” with no use of technology
Answers
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.

A county has recently evolved from underdeveloped to developed and the birth and death rate have stabilized, This is known as Demographic transition. Thus, the correct option is B.
What is Demographic transition?Demographic transition is a phenomenon and the theory which refers to the historical shift from the high birth rates and high death rates in the societies with minimal technology, education especially of the women of the society and the economic development, to the low birth rates and low death rates in the societies with advanced technology, education and economic development of the whole society, as well as the different stages between these two scenarios.
The rise in the demand for human capital and its impact on the decline in the gender wage gap of the society during the nineteenth and the twentieth centuries period have contributed to the onset of the overall demographic transition of the society as a whole.
