Answer:
Since the gravitational potential energy of an object is directly proportional to its height above the zero position, a doubling of the height will result in a doubling of the gravitational potential energy. A tripling of the height will result in a tripling of the gravitational potential energy.

How are mitosis and meiosis the same and different?
Answer the lab question, “What is the effect of the inheritance of one trait on the inheritance of a second trait?” with a hypothesis. Remember that you can either assume that the two genes are independent or that they are linked. What results would you expect in either case?
Answer:
please give me branlist and follow
Explanation:
One hypothesis would be "The inheritance of one trait does not affect the inheritance of another trait". It can be explained with the help of law of independent assortment. It states that the genes are randomly distributed in the gametes, that is, independent of each other.

5) It is said that the hottest layer of the earth
is the core (outer core and the inner core)
and that is where metal is found. Why
can't metal melt in the core?
Answer:
please give me brainlist and follow
Explanation:
The churning metal of the outer core creates and sustains Earth's magnetic field. The hottest part of the core is actually the Bullen discontinuity, where temperatures reach 6,000° Celsius (10,800° Fahrenheit)—as hot as the surface of the sun. The inner core is a hot, dense ball of (mostly) iron.
Need help on this please!!!
Answer:
1. D
2. G
3. C
4. A
Explanation:
An endothermic reaction is one that absorbs or uses heat energy. Its polar — er thermal — opposite, exothermic describes a reaction that makes or gives off heat. It can be easy to confuse the two, but if you can remember that endo means “in” and exo means "out,". Ectotherm, any so-called cold-blooded animal—that is, any animal whose regulation of body temperature depends on external sources, such as sunlight or a heated rock surface. The ectotherms include the fishes, amphibians, reptiles, and invertebrates.
Larger animals can keep their heat for a longer time than smaller animals. A small animal has a greater surface area for its size compared to an adult animal. That is why small animal, as well as a baby, is more prone to heat loss. Larger animals can keep their heat for a longer time.
Why is it important that gametes be haploid?
I GOT YOU SO EASY
Answer:because when the sperm and the egg fuse together the cell will have 46 chromosomes.
Answer:
It is important that chromosomes are haploids because when the sperm and the egg fuse together the cell will have 46 chromosomes. polar bodies are haploid cells produced during meiosis which are smaller in size compared to the gamete and will disintegrate

Which of the following best predicts a long term effect of the differences between the E and Z strains
Answer:The difference between the forms of the sex pheromone 11−TDA produced by E and Z strains will act as a prezygotic reproductive barrier leading to sympatric speciation.
Explanation:The difference between the forms of the sex pheromone 11−TDA produced by E and Z strains will act as a prezygotic reproductive barrier leading to sympatric speciation.
Conducting long-term studies to observe the effects of E and Z strains would best predict the long-term effects of their differences.
What are E and Z strains?In biology, E and Z strains are used to describe different genetic variants or subpopulations of a species. These designations are often used in studies of insects, particularly in the context of reproductive isolation and speciation.
For example, in some species of moths, E and Z strains are distinguished based on differences in the production of sex pheromones. Females of each strain produce different forms of the pheromone, which may act as a barrier to mating between individuals of different strains. Over time, this could lead to the development of distinct populations that are reproductively isolated from each other, potentially leading to the formation of new species. Other factors, such as geographic isolation and genetic drift, may also contribute to speciation in these and other organisms.

Describe how brine pools function
Explanation:
Brine pools are sometimes called sea floor "lakes" because the dense brine does not easily mix with overlying seawater. The high salinity raises the density of the brine, which creates a distinct surface and shoreline for the pool. When submarines dive into brine pools, they float on the brine surface due to the high density

Heterotrophic nutrition can be one of three types , holozoic, saprophytic or parasitic. Holozoic nutrition can be seen in most vertebrates and some unicellular organisms like the amoeba. Saprophytic nutrition is where the organisms feed on dead and decaying matter. Examples include bacteria and fungi.

Explanation:
7 DDT is a pesticide that was once widely used to control agricultural pests and
mosquitoes. However, this pesticide caused the eggshells of certain birds, including the
brown pelican, to become fragile and thin. The adults would then accidentally crush the
eggs while trying to incubate them.
What happened to brown pecan populations as a result of DDT use by humans?
A The populations increased much more slowly.
B The populations decreased as fewer eggs survived long enough to hatch.
C The populations remained stable over time.
D The populations increased as pelicans laid more eggs so that more offspring would
survive.
Answer:
The answer is B. The populations decreased as fewer eggs survived long enough to hatch.

The initial velocity of an enzyme catalyzed reaction is determined by:_________.
a. graphically determining 1/2 Vmax.
b. calculating the amount of product formed over time while the amount of product is increasing in a linear manner.
c. calculating the amount of product formed over time from the beginning to the end of the reaction.
d. graphing the absorbances of known concentrations
Answer:
calculating the amount of product formed over time while the amount of product is increasing in a linear manner. ( B )
Explanation:
The initial velocity of an enzyme catalyzed reaction is determined by Calculating the amount of product formed over time while the amount of product is increasing in a linear manner
Initial Velocity of an enzyme is the described in relation to the amount of product produced per unit time at the beginning of a reaction.
The initial velocity of an enzyme reaction is determined by calculating the amount of product over time while it is increasing in a linear manner (Option B).
What is an enzyme?An enzyme is a protein that may act as a biological catalyst for a particular chemical reaction.
Enzymes work by speeding up the velocity of a given chemical reaction.The initial velocity of an enzyme can be calculated by determining the amount of product of the chemical reaction.In conclusion, the initial velocity of an enzyme reaction is determined by calculating the amount of product over time while it is increasing in a linear manner (Option B).
