What is the Law of Universal Gravitation and how did it differ from the understanding of the motion before Newton theorized it?
How do you think Newton’s discoveries help to pave the way for his Three Laws of
Motion?
Answer:
While Copernicus rightly observed that the planets revolve around the Sun, it was Kepler who correctly defined their orbits. At the age of 27, Kepler became the assistant of a wealthy astronomer, Tycho Brahe, who asked him to define the orbit of Mars. Brahe had collected a lifetime of astronomical observations, which, on his death, passed into Kepler’s hands. (Brahe, who had his own Earth-centered model of the Universe, withheld the bulk of his observations from Kepler at least in part because he did not want Kepler to use them to prove Copernican theory correct.) Using these observations, Kepler found that the orbits of the planets followed three laws.

difference between animal cells and plants cells
Answer:
A plant cell have a vacuole, chloroplasts and A cell wall
Vacuole - Gives the cell shape
Chloroplasts - Contain a green pigment (turns the plant green) To do with photosynthesis.
Cell Wall - Holds the cell up and keeps it in a rigid structure.

9. Which food would you expect to have the lowest lipid levels?
a. Olives
b. Pistachios
c. Wheat crackers
d. Sesame seeds
The food expect to have the lowest lipid levels is sesame seeds. The correct option is d.
What is lipid?Lipids are hydrocarbon-containing molecules that serve as the foundation for the structure and function of living cells.
Lipids include fats, oils, waxes, vitamins (such as A, D, E, and K), hormones, and the majority of the cell membrane that is not made of protein.
Carbon, hydrogen, and oxygen are the same elements found in lipids as they are in carbohydrates.
Lipids, on the other hand, are primarily composed of hydrocarbon chains and contain fewer polar hydroxyl groups. As a result, most lipids are nonpolar hydrophobic molecules.
Sesame seeds are high in saturated fat (15%), polyunsaturated fat (41%), and monounsaturated fat (39%).
According to research, eating more polyunsaturated and monounsaturated fat than saturated fat may help lower your cholesterol and reduce your risk of heart disease.
Thus, the correct option is d.

The ____________________ is the reproductive structure of gymnosperms.
Answer:
seed cones and pollen cones
Explanation:
In gymnosperms, their reproductive structures include the pollen cones, which produce pollen grains or the male gametophyte; and the seed cones, which produce female gametophyte.
Answer:
The Answer Is "Cones"
Explanation:
Why? Well, the cones spread from the male cones to the female cones... Then, the female cones put this sticky stuff on the cone called, " Ovule" Finally, it creates the cycle once again.

if humans run out of following resources, which resource would be most difficult to replace
Answer:
Petroleum
Explanation:
Like all fossil fuels, petroleum is a nonrenewable energy resource. This means that it is a resource that cannot be replaced as quickly as humans use up existing supplies. Humans face a problem because once petroleum reserves begin to run out, there won't be enough fuel to power all the automobiles in the world.

Which statement about oogenesis is correct?
A. Diploid secondary oocytes undergo meiosis II to form a haploid ootid cell and a polar body.
B. Two diploid secondary oocytes undergo meiosis II to form four haploid ootid cells.
C. Haploid secondary oocytes undergo meiosis I to form a haploid ootid cell and a polar body.
D. Haploid secondary oocytes undergo meiosis II to form a diploid ootid cell.
The statement which is true about oogenesis is that the diploid secondary oocytes undergo meiosis II to form a haploid ootid cell and a polar body. Thus, the correct option for this question is A.
What is Meiosis?Meiosis may be defined as a type of cell division in which each parental cell is divided into four daughter cells. These daughter cells are genetically unique to the parental cells and are haploid in nature. Germ cells (gamete cells) are typically divided through this mode of cell division.
Oogenesis may be characterized as the process of female gamete formation including the formation of an oocyte from an oogonium followed by meiotic division. During the process of oogenesis, a haploid ootid cell and a polar body are formed with the help of meiotic division.
Therefore, the statement which is true about oogenesis is that the diploid secondary oocytes undergo meiosis II to form a haploid ootid cell and a polar body. Thus, the correct option for this question is A.
