a 4.24 kg marble slab has a volume of 1564 cm^3. what is it's density in g/cm^3? give you answer to the nearest tenth
Thhe density of the marble, given the data from the question is 2.7 g/cm³
What is density?The density of a substance is simply defined as the mass of the subtance per unit volume of the substance. Mathematically, it can be expressed as
Density = mass / volume
With the above formula, we can obtain the density of the marble. Details below
How to determine the density of the marbleThe following data were obtained from the question:
Mass of marble = 4.24 Kg = 4.24 × 1000 = 4240 gVolume of marble = 1564 cm³Density of marble =?The density of the marble can be obtained as follow:
Density = mass / volume
Density of marble = 4240 / 1564
Density of marble = 2.7 g/cm³
Thus, the density of the marble is 2.7 g/cm³

Which of the following is not a part of Darwin's theory of evolution?
a. Changes in organisms occur immediately.
b. Organisms change over time.
c. Species evolution occurs through natural selection.
d. Organisms developed from common ancestors.
Answer:
a
Explanation:
Evolution is supposed to take place over a long period of time and is made up of small changes
Changes in the evolution take time. The correct answer is option a.
What is the important key for the survival of any species ?It is that the species which are prone to the adaptation and are flexible enough to get to the new type of adaptation are called as the fittest species and they invade the land.
Organisms definitely do change with time where the organisms are thought to have a proper phylogeny behaviors where the different species are thought to have changed with the time where suppose one species that is the species which tend to change with the changing environment and tend to adapt.
Organisms definitely developed from common ancestors for example in the case of primates it is having the common phylogeny behavior as the species do share the common ancestry. Various primates are having the same behaviors.

Top predators are often keystone species in their habitat. Explain what happens to the biodiversity of an ecosystem when a top predator is deliberately removed from the ecosystem in which it lives.
Answer:
The ecosystem will fall out of balance.
Explanation:
The ecosystem will fall out of balance because once you remove the top predator, the plant eaters will grow in numbers, they will eat all of the vegetation, and will either need to adapt or die. Predators are very important, as is everything in the food chain
c) In dense rainforest, plants that grow close to the forest floor tend to have lower rates of photosynthesis than the very tall trees. Suggest why this might be.
Answer:
The reason why plants that grow close to the forest floor tend to have lower rates of photosynthesis is because sunlight is a vital component in the production of glucose. Using logic, you can see that the tree cause larger shadows to form—blocking sunlight.

describe the motion of the particles
of a liquid when heat added.
Answer:
Hope this helps!
Explanation:
If a liquid is heated the particles are given more energy and move faster and faster expanding the liquid. The most energetic particles at the surface escape from the surface of the liquid as a vapour as it gets warmer. Liquids evaporate faster as they heat up and more particles have enough energy to break away.
Answer:
The liquid turns into a gas and the particles move around freely and fast.

Sample Response: Federalists believed in a strong central government. They argued in favor of separation of powers: the division of the government into three separate branches whose powers balance each other. They felt this would be necessary and helpful. On the other hand, Anti-Federalists were fearful that the separation of powers would not equally balance power. They did not believe that this separation could occur in a fair way.
Answer:
This represents a conflict Federalist vs antiferalists
Explanation:
Federalists and anti-federalists were two groups formed during the conventions to decide how the country would be governed and to decide the nation's legislative body through the federal constitution.
The federalists were represented by John Adams, Alexander Hamilton and George Washington who preached the need to establish a central government divided into three spheres that complemented and acted on different elements. The anti-federalists, on the other hand, led by Patrick Henry, believed that federalism gave the president too much power, allowing him to act like a king and that he could abuse power, in addition to exploiting the nation.
The ideological differences of these two groups led to many discussions and conflicts, but it ended with the adoption of federalism in the country.

Yeast cells obtain energy under anaerobic conditions through the
process of...
Answer:
If no oxygen is available, yeast will switch over to a process called anaerobic respiration - in this process, glucose (sugar) is fermented to produce energy, carbon dioxide, and ethanol. ... The thing about respiration is that the yeast cells only do it for the sake of producing energy
The conditions through which yeast cells obtain energy under a anaerobic conditions through the process called fermentation.
Yeast cells are unicellular fungal organisms.
They are known to be different from other fungi because they reproduce through the process of budding.
For these yeast cells to be able to function properly energy is needed for their metabolism and reproductive.
Fermentation is the anaerobic (absence of oxygen) break down of glucose molecules with formation of pyruvate.
The pyruvate generated is converted to Adenosine triphosphate (ATP) which is the form of energy used by these yeast cells.
Therefore, yeast cells obtain energy under anaerobic conditions through the process of fermentation.
