Even though the Earth's Inner core is hotter than the
liquid outer core, it is still solld because -
Answer: The inner core is solid because it is made of very dense, or heavy, materials - like iron and nickel. Even though it is very hot, these materials don't "melt" very easily, so they stay solid. Answer 3: It turns out that many materials can be a solid at a higher temperature if the pressure is also higher.

Which statement correctly describes a difference between asexual and sexual reproduction?
Answer:
B) Asexual reproduction involves one parent, and sexual reproduction involves two parents.
Explanation:
In asexual reproduction, offspring formed from only one parent whereas, in sexual reproduction, offspring produces from two parents. The offspring is identical to the parent in asexual reproduction while on the other hand, offspring is different from their parents. Sexual reproduction increases the chances of survival of the species due to genetic diversity whereas asexual reproduction has limited chances of survival due to lack of genetic diversity.
Asexual reproduction involves the production of offspring without the involvement of gametes, resulting in genetically identical offspring. On the other hand, sexual reproduction involves the fusion of gametes from two parents, resulting in offspring with genetic variation.
Asexual reproduction and sexual reproduction are two different methods of producing offspring in living organisms. Here are the differences between them:
1. Asexual reproduction:
Asexual reproduction involves the production of offspring from a single parent without the involvement of gametes (sex cells). This means that the offspring are genetically identical or clones of the parent.
Examples of asexual reproduction include binary fission in bacteria, budding in yeast, and regeneration in starfish. In binary fission, a single-celled organism divides into two identical cells. In budding, a small bud grows on the parent organism and eventually detaches to become a new individual. In regeneration, an organism can regrow a lost body part and develop into a complete organism.
2. Sexual reproduction:
Sexual reproduction involves the fusion of gametes from two parents to produce offspring. Gametes are specialized sex cells, such as sperm and eggs, which contain half of the genetic material of the parent.
In sexual reproduction, the offspring inherit genetic information from both parents, leading to genetic variation. This genetic diversity is important for the survival and adaptation of species over time.
Examples of sexual reproduction include humans, animals, and many plants. In humans, sperm from the male parent fertilizes an egg from the female parent, resulting in the formation of a zygote. The zygote then undergoes development to form a new individual with a unique combination of genetic traits.

Snapdragons show incomplete dominance for the flower color trait. A cross between snapdragon plants with red flowers and plants with white flowers produces F1 offspring with pink flowers.
When an F1 plant is self-pollinated, what percentage of its F2 offspring will be expected to have red flowers
Based on inheritance laws, it is expected none of the offspring will have red flowers.
What is incomplete dominance?This occurs when a specific trait or allele is not completely expressed. In this case, the colors red and white are not completely expressed but they mix in the offspring.
What would be the dominant trait of the F2 generation?Considering the pink flower will self-pollinate, it is expected the F2 generation has exactly the same traits as the F1 generation because there are no new genes or traits being combined. This means none of the F2 offspring will have red flowers, instead all plants will have pink flowers.

The difference between Secondary and Primary Succession is...
A. Primary only happens after a fire.
B. Secondary is starting from scratch with big rocks.
C. Secondary begins with soil, but no biotic (living) things.
Answer:
C.
Explanation:
This is because primary succession is newly formed logs that are colonized by living things. Seconday succession is there were living things there once but due to disturbance life is lost and started over which could take decades.

Which of the following would provide the best evidence to support the claim that acid rain has a long-term effect on the stability of ecosystems?
Extinction of aquatic and terrestrial organisms would occur, decreasing species diversity and ecosystem stability.
The mutation rate would increase and new species would evolve, destabilizing ecosystems.
The pH level would increase and become intolerable to organisms, leading to decreased species diversity and ecosystem stability.
Habitat loss would occur, forcing organisms to adapt to new surroundings until the ecosystem eventually stabilized.
Answer:
A
Explanation:
Extinction of aquatic and terrestrial organisms would occur, decreasing species diversity and ecosystem stability.
What motion does the graph above show the object during the time interval from 3
seconds to almost 4 seconds?
Answer:
I am not 100% sure but my best guess would be the object is moving backwards/falling.
Explanation:
The graph shows the position of the object going from almost 9.0 to below zero. There are many situations that could fit this. Such as, something going above and below sea level. OR something moving in front and behind a certain point. My best guess would be moving backward towards an object OR falling from a certain point.
why are viruses not placed into one of the five kingdoms

Answer:
7 thats answer
Explanation:
14. The elements in group_
are the most reactive metals.
15. The elements in group_
are the most reactive nonmetals.
16. The elements in group_
are very unreactive.
17. The elements in group_
react very violently with water.
Answer:
14 Hydrogen is a very reactive gas, and the alkali metals are even more reactive. In fact, they are the most reactive metals and, along with the elements in group 17, are the most reactive of all elements.
15 The halogen group of elements is the most reactive of the nonmetals. It is also the most reactive group of all chemical elements. Fluorine is the most reactive element in this group. Halogens are highly reactive because they are all electronegative.
16 Group 8A — The Noble or Inert Gases. Group 8A (or VIIIA) of the periodic table are the noble gases or inert gases: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). The name comes from the fact that these elements are virtually unreactive towards other elements or compounds.
17 Group 1: Alkali Metals
Group 1 elements are called alkali metals because of their ability to displace H2(g) from water and create a basic solution. Alkali metals are also known to react violently and explosively with water.

O Analyze the patient's diet to quantify cholesterol intake
O Determine the exact amount of cholesterol in the patient's blood
O Determine if the cholesterol will lead to high blood pressure
Answer:
Analyze the patient's diet to quantify cholesterol intake
Explanation:
This is because since the patient family consumed more of red meat, it should be analysed. Because researches find out that red meat either processed or unprocessed contain more protein than fish, milk, and it can raise cholesterol levels. Red meat contain high cholesterol and increaee in cholesterol levels can lead to coronary heart diseases.
