Explanation:
We respect Dr. Trudeau and all those earlier scientists who did the best they could within the contemporary understanding of the problem they addressed and utilizing the materials and technology they had at hand. Modern-day biologists like to talk about resistance/susceptibility genes and patterns of inheritance, rather than family blood. They think about infectious disease in terms of microbes and pathogenicity, rather than speaking of bad humors. They have identified vitamins and other nutrients that are abundant in some foodstuffs and lacking in other that are essential for optimal immune function. Without the benefit of such modern formulations, Dr. Trudeau, by a disciplined application of scientific curiosity and careful, clever methodology, shed light on each of these concerns, light that helped to illuminate the minds of scientists who came after. Still, a look at his original paper leaves us wondering, were the rabbits genetically identical? Probably not! Why? Were they all of the same sex and age? Couldn’t he have given the animals kept on short rations just a smaller amount of the same varieties of food available to the animals fed abundantly—after all, there might be some important nutrient missing in potatoes. In light of the title of the paper, why not measure bacterial numbers in the rabbits on post mortem rather than just survival time? (In a subsequent paper, he did exactly that.) Once you start critiquing an experiment from 100 years ago, or 10 years ago, or sometimes even last year, it’s hard to stop.

8. a) How are the events in the menstrual cycle triggered by the body? (1 point)
Will be marking brainliest!!
There is a supply of undeveloped eggs in the ovaries. At the beginning of the menstrual cycle, between 6 and 12 undeveloped eggs in the ovaries start to mature. A layer of cells grows around them. At around day 5 of the menstrual cycle, the biggest follicle will continue to grow for another week. At around day 14, the follicle breaks apart, and the wall of the ovary ruptures. The egg is released from the ovary into the fallopian tube, where it can get fertilized. This process is called ovulation. The uterus also changes during the course of the menstrual cycle. It has a lining of cells on the inside, kind of like a cushion with a lot of blood vessels. Fallopian tubes connect the ovaries and the uterus. The uterine cycle begins with menstruation. This is the process through which most of the lining and blood from the last uterine cycle are cleared out of the uterus to prepare for a new attempt at pregnancy. Starting at around day 5, the lining starts to grow. It builds back up to prepare a place for the egg to grow if it gets fertilized. After ovulation, the egg reaches the oviduct. If sperm cells have entered the vagina during intercourse, fertilization may occur at any time in the next two weeks. Then the fertilized egg will move into the uterus and implant itself into the lining, where development will begin.
Please mark BRAINLIEST!
The events in the menstrual cycle are primarily triggered by hormonal signals from the body. The menstrual cycle is a complex process regulated by the interplay of hormones produced by the hypothalamus, pituitary gland, and ovaries.
1. Hypothalamus: The hypothalamus, a region of the brain, releases gonadotropin-releasing hormone (GnRH) in a pulsatile manner. GnRH stimulates the pituitary gland.
2. Pituitary gland: In response to GnRH, the pituitary gland secretes two important hormones: follicle-stimulating hormone (FSH) and luteinizing hormone (LH).
3. Follicular phase: At the beginning of the menstrual cycle, FSH stimulates the growth and maturation of ovarian follicles, which contain the developing eggs (oocytes).
As the follicles grow, they produce estrogen, a hormone that helps prepare the uterus for a possible pregnancy.
4. Ovulation: As the estrogen levels rise, it triggers a surge in LH production by the pituitary gland. The LH surge leads to the release of a mature egg from the ovary, a process called ovulation.
5. Luteal phase: After ovulation, the ruptured follicle in the ovary transforms into a structure called the corpus luteum. The corpus luteum produces progesterone, which prepares the uterus for potential implantation of a fertilized egg.
6. Menstruation: If pregnancy does not occur, the levels of estrogen and progesterone decline. This drop in hormone levels triggers the shedding of the uterine lining, resulting in menstrual bleeding.

Enzymes can be regulated in a multitude of ways. One such way is by covalent modification, in which functional groups are attached to or removed from the enzyme. One such functional group that can be added to an enzyme is a phosphate group. Depending on the enzyme, addition of a phosphate group may increase or decrease that enzyme's activity. Which of the following is the general name of an enzyme that functions to add phosphate groups to its substrate?
a. Oxidoreductases
b. Ligases
c. Hydrolases
d. Isomerases
e. Transferases
Answer:
Option E
Explanation:
Transferase enzyme are able to transfer a molecule or atom from one compound to the other.
For example – In the process of phosphorolysis, add phosphate to the substrate group .
X-Y + Z = X + Z-Y
Here Z in the phosphate group
Hence, option E is correct
Cohesion, surface tension, and adhesion are the properties of water molecules that ________
Answer:
Hydrogen bonding
Explanation:
Hydrogen bonds between surface water molecules resist being stretched.
Cohesion, surface tension, and adhesion are the properties of water molecules that are all a result of hydrogen bonding.
Hydrogen bonding is a transient intermolecular force caused by the electrical attraction between partially positive hydrogen atoms and partially negative F, O, or N atoms.
The attraction between partially positive hydrogen atoms and partially negative oxygen atoms of adjacent water molecules that form hydrogen bonding takes place in water.The differences in electronegativity between hydrogen and oxygen atoms lead to associated properties that are Cohesion, surface tension, and adhesion. Cohesion - Attraction between water moleculesAdhesion - the attraction between the water molecules and other compounds.The surface tension - sticking of water molecules to one anotherThus, the correct answer is - are all a result of hydrogen bonding.

Ecologists are interested in quantifying different kinds of biodiversity. In each of the two studies outlined here, which kind of biodiversity are ecologists studying?
Ecologists establish 20 small areas, called plots, randomly scattered across a California grassland. They count the number of different plant species present in each plot.
By noting how many species appear in the plots, the ecologists are able to estimate the number of species in the entire grassland.
a. Genetic diversity
b. Functional diversity
c.Ecosystem diversity
d. Species diversity
Ecologists draw blood samples from basking shark (Cetorhinus maximus) specimens caught from a single large population in the Atlantic Ocean. From each blood sample, the ecologists isolate DNA. Comparing several DNA sequences across the individuals that were sampled, the ecologists are able to estimate the variation in DNA sequences in the entire population.
a. Genetic diversity
b. Ecosystem diversity
c. Species diversity
d. Functional diversity
One way to think about the importance of biodiversity is simply to think in terms of natural capital: the roles that genes, species, ecosystems, and ecological processes play in supporting human society and a healthy biosphere. Which of the following are benefits provided by biodiversity?
a. Controlling pests
b. Providing medically useful chemicals
c. Keeping topsoil fertile
d. Eliminating the ozone hole
Answer:
1. --> d. Species diversity
2. --> a. Genetic diversity
3. --> a. Controlling pests, b. Providing medically useful chemicals , and c. Keeping topsoil fertile
Explanation:
1) Kinds of biodiversity
Genetic diversity: Among species. Refers to genes variability among species that differentiate them and allows them to adapt to different environments. The genetic charge of one species differs from other species´ genetic charge. Species diversity: Refers to the diversity of species, which can be measured by: Species richness: Number of species in a defined unit sample, Species abundance: Describe the distribution of the species abundance.Species richness is the number of species present in a sample, within a community, habitat or microhabitat, ecosystem, landscape, region, or any well-defined spatial unit. It is simple and easy to interpret. It is the simplest and straightforward measure of biodiversity. It is just a count of species, with no need for abundance data. In some cases, this can be the cause of criticism, as it ignores information about the species-abundance distribution.
2) Ecosystem services
When talking about ecosystem services, we are referring to the benefits that ecosystems provide us. There are four types of ecosystem services:
Provision or supply:These are the products obtained by nature to be used or consumed, directly or with previous processing. Among them, we might mention food, clear fresh-water, fertile soils, geotic materials, raw materials (that can be used for clothing, construction), renewable fuels, biochemical compounds, pharmacological/medicinal resources, among others.
Regulation:Refers to ecological processes that improve life. Among others, we might mention climate regulation, CO² absorption, water purification, air purification, erosion control, natural disaster avoidance such as flooding, soil fertility maintenance, waste recycling, pests/plagues control, etc.
Cultural:Refers to not the material benefits. Ecosystems also provide a recreational place or area to spend time, to learn, provides a spiritual/religious space, is a source of inspiration, it is considered to be cultural patrimony, and the source of scientific knowledge.

5. What is symbolic about the Dragon’s Cup and why was it added to the movie?
Beowulf and Grendel's mother formed an alliance, and the dragon's cup served as a sign of their understanding. It is appropriate for the film, and perhaps alludes to Beowulf and the dragon's conflict.
What is symbolic about the Dragon’s Cup?The dragon's hoard of treasure eloquently symbolizes both, the flimsiness of human desires and the changeability of time. The wealth in the dragon's tomb is plentiful, but no one can use it.
Gardner uses the dragon as a symbol for life's sorrow—the kind of misery that might result in the gloomy beliefs (and disgusting social behaviors) he eventually shares with Grendel.
Beowulf grabs a knife from his belt and stabs the dragon's flank desperately. The fatal strike causes the writhing serpent to wither.
But as soon as Beowulf achieves victory, the cut on his neck starts to enlarge and burn. He understands that the venom from the dragon bite is killing him.
Therefore, flimsiness of human desires and the changeability of time symbolic about the Dragon’s Cup.
