Answer:
As a cell grows bigger, its internal volume enlarges and the cell membrane expands. Unfortunately, the volume increases more rapidly than does the surface area, and so the relative amount of surface area available to pass materials to a unit volume of the cell steadily decreases.

WHat two factors determine the amount of humidity in the air
Answer:
Heat and pressure
Explanation:
Warmer air, for example rain forest air, as high humidity. Warmer air can hold more humidity.
10 c = 100%
20 c = 52%
30 c = 28%
Areas with large amount of surface water was high humidity.
Cold air holds less humidity
The first species we see in this area is Globus slimius. Describe a scenario which may have led to the extinction or evolution of the Globus slimius species. Why would this scenario have led to the organism's extinction or evolution?
Answer:
ok first human and animals can not live without water and global warming is becoming a really bad during these harsh times so while our planet is getting warming i'm starting to worry about how in the far future that we might start to experience droughts our animals will die and we will have our crops die also then we will have no food to go around maybe scientists will come up with a way but for this let's say we did not at all came up with a way to live we will slowly become a desert and our planet will become a wasteland like this

write a paragraph with 10+ sentences about the peridodic table. also write another paragraph with 10+ sentences about density
Answer:
Periodic table:
The periodic table is a chart that arranges the chemical elements in a useful, logical manner. Elements are listed in order of increasing atomic number, lined up so elements that exhibit similar properties are arranged in the same row or column as others.
Although Dmitri Mendeleev is most often cited as the inventor of the modern periodic table, his table was just the first to gain scientific credibility. It wasn't the first table that organized the elements according to periodic properties.
There are about 94 elements on the periodic table that occur in nature. All of the other elements are strictly human-made. Some sources state more elements occur naturally because heavy elements may transition between elements as they undergo radioactive decay.
Technetium was the first element to be made artificially. It is the lightest element that has only radioactive isotopes (none are stable).
The International Union of Pure Applied Chemistry, IUPAC, revises the periodic table as new data becomes available. At the time of this writing, the most recent version of the periodic table was approved in December 2018.
The rows of the periodic table are called periods. An element's period number is the highest unexcited energy level for an electron of that element.
Columns of elements help to distinguish groups in the periodic table. Elements within a group share several common properties and often have the same outer electron arrangement.
Most of the elements on the periodic table are metals. The alkali metals, alkaline earth, basic metals, transition metals, lanthanides, and actinides all are groups of metals.
The present periodic table has room for 118 elements. Elements aren't discovered or created in order of atomic number. Scientists are working on creating and verifying elements 119 and 120, which will change the appearance of the table, though they were working on element 120 before element 119. Most likely, element 119 will be positioned directly below francium and element 120 directly below radium. Chemists may create much heavier elements that may be more stable because of the special properties of certain combinations of proton and neutron numbers.
Although you might expect atoms of an element to get larger as their atomic number increases, this does not always occur because the size of an atom is determined by the diameter of its electron shell. In fact, element atoms usually decrease in size as you move from left to right across a row.
The main difference between the modern periodic table and Mendeleev's periodic table is that Mendeleev's table arranged the elements in order of increasing atomic weight, while the modern table orders the elements by increasing atomic number. For the most part, the order of the elements is the same between both tables, though there are exceptions.
Destiny:
That is, density (p) is equal to the total mass (M) divided by total volume (v). This formula can be used to determine the density of any substance. Common units for the measurement of density include grams (g), milliliters (ml), or grams per cubic centimeter. For instance, if there are 50 grams of a given substance within a cubic centimeter, that unit’s density is 50g/mm3.
Density can vary according to temperature and pressure. Applying pressure to an object decreases volume, which then increases density. Increasing the temperature of an object almost always decreases its density by increasing its volume.
By heating the bottom of a volume, especially a fluid volume such as a liquid or gas, convection causes the substance to rise, thus increasing the volume. The temperature variation is typically minor in solids and most liquids, but much greater in gases. The abbreviations to know are:
NTP: Normal Temperature and Pressure. Equal to 20 degrees C (68 F) and 1 atmosphere of pressure. Our examples below are all at NTP.
STP: Standard Temperature and Pressure. Equal to 0 degrees C (32 F) and 1 atmosphere of pressure.
These standardized pressures and temperatures make it possible to confirm equal densities are being used regardless of the application.
Identity the process that occurs in this organelle, and explain the importance of
this process to the survival of organisms
not sure if this is what you need.
The process that occurs in this cell organelle known as mitochondria is cellular respiration. The importance of this process is understood by the fact that it derives energy for the accomplishment of metabolic functions.
What is a Cell organelle?A cell organelle may be defined as a type of small structure that is present inside a cell and is significantly surrounded by a membrane in order to perform a specific function for the overall survival of an organism.
This process in the mitochondria is known as cellular respiration. Through which the molecules of glucose are significantly broken down in the presence of oxygen in order to liberate energy in the form of ATP which is known as the energy currency of the cell. The ATP that is produced by this reaction or process carries out all essential functions of life.

From the moth’s point of view, is the ability to be seen an advantage (known as an advantageous trait) or disadvantage (known as a disadvantageous trait)? Explain your reasoning.
Answer:
Disadvantageeous trait
Explanation
Since the moth is not high up in the food chain, it would want to hide from others by blending in with its surroundings rather than be easily seen as that would just make it easier for them to become easy prey for anything higher up in the food chain nearby.

The energy in uranium is used to make electricity in a nuclear power plant.
How is the energy stored in uranium?
A. in chemical bonds
B. as light energy
C. as kinetic energy
D. in the nucleus
Answer:
D. in the nucleus
Explanation:
Uranium is a natural radioactive chemical element with the chemical symbol "U" and an atomic number of 92. Uranium is used for generating nuclear fuels which are typically used in powering atomic bombs and nuclear reactors in the field of electricity generation.
When ignited, a uranium compound burns with a green flame. The wavelength of the light given off by this flame is greater than that of ultraviolet light which typically ranges from 100nm to 400nm. Where, nm is represents nanometer.
Basically, when ignited, a uranium compound burns with a green flame having a wavelength of 4.30 x 10^-7m to 5 x 10^-7m.
The energy in uranium is used to make electricity in a nuclear power plant.
This energy is stored in the nucleus of uranium and are released through fission because the uranium atom is highly unstable due to its large number of protons. The nucleus is split spontaneously into several smaller nuclei and thus, releasing energy in the process.
