Explanation:
This stadium can hold 100,000, or 1x10, people. The
number of atoms in a grain of iron is about 1x 1016,
Would you need 1 x 10° or 1 x 10' stadiums to hold
the same number of people as the number of atoms in
a grain of iron? Explain your answer,
Answer:
1 x 10^13 stadiums will be needed in this scenario
Explanation:
We are told that
1 stadium holds = 1 × 10^5 people and
Number of iron atoms = 1 × 10^18 atoms
If the stadium carries an equivalent number of atoms as that of people.
We can infer that 1 stadium will carry 1 × 10^5 atoms.
The calculation to determine the number of stadiums would then be 1 × 10^18 divided by 10^5 atoms/stadium which was gotten by dividing the total number of atoms by the number of atoms per stadium.
Number of stadiums = Total number of atoms ÷ Number of atoms per stadium
= 1 × 10^18 atoms ÷ 1 × 10^5 atoms/stadium
= 1 × 10^13 Stadiums
This means that 1 × 10^18 atoms would occupy 1 × 10^13 stadiums

Explanation:
what does it mean if something undergoes a "mutation"?
Students planted the same type and number of seeds in pots A and B. The amount and type of soil in both pots were also the same. Each plant received the same amount of water each week. Pot A was placed by a sunny window. Pot B was placed in a closet. After four weeks, the students observed the plants in both pots. The plants in pot A were green with thick stems. The plants in pot B were yellow with thin stems. Which statement best explains why the plants in pot A were different from the plants in pot B?
Answer:
C) Pot A received more sunlight than pot B.
Explanation:
Seeds or plants require some very important factor to grow that include carbon-dioxide, water and sunlight to undergo the process of photosynthesis.
Photosynthesis is the process by which plants make their own food by utilizing carbon-dioxide and water in the presence of sunlight and releases oxygen and energy.
In the given example, both the plants received equal amount of water and soil but the difference is in the position of the plant, in which plant A was placed by a sunny window from where plant have undergoes the photosynthesis process and grew with green with thick stems. while plant B was placed in a closet where no sunlight was present and the plant grew with yellow with thin stems.
Hence, the correct answer is "C) Pot A received more sunlight than pot B. "
Answer:
Answer: C) Pot A received more sunlight than pot B
Explanation:
Here's why: Pot A received more sunlight than pot B is correct. Plants need sunlight in order to make chlorophyll. Chlorophyll is the chemical that makes plants green.

If the function of an aquaporin is inhibited, how would the transport of water into the cell be affected? (3 points)
A. Water molecules will no longer be able to cross the cell membrane.
B. Water molecules will move across the cell membrane at a much slower rate.
C. Water molecules will only be able to cross the cell membrane by active
transport
D. Water molecules will move across the cell membrane at a faster rate with late regulation from the aquaporin.
Answer:
D. Water molecules will move across the cell membrane at a faster rate with late regulation from the aquaporin.
If the function of an aquaporin is inhibited, water molecules will move across the cell membrane at a much slower rate. Thus, the correct option for this question is B.
What is the function of Aquaporin?The fundamental function of most aquaporins is to conduct the transport of water molecules across the cell membrane with respect to osmotic gradients that are significantly constructed by active solute transport.
Aquaporins are transmembrane proteins that remarkably form the channels and facilitate the rapid transportation of water molecules in both directions of the cell membrane.
If the function of an aquaporin is inhibited, the water movement is facilitated by diffusion also. So, a slow rate of water movement is carried out in the absence of aquaporins.
Therefore, water molecules will move across the cell membrane at a much slower rate, if the function of an aquaporin is inhibited. Thus, the correct option for this question is B.

You want to alter this model so it also shows the flow of energy through the biosphere. To start, you draw a sun. Then, you draw arrows from the sun to the trees and the photosynthetic algae, which are examples of . From there, arrows would be drawn to the moose and the fish, which are . Finally, you would draw arrows connecting groups to , which are represented by microbes responsible for decomposition on this model.
Answer:
The correct answer is :
1. Autotrophs
2. Heterotrophs
3. Saprophytes
Explanation:
In a flow of energy through a biosphere, organisms that trap sunlight for producing their energy on their own known as autotrophs such as plants and photosynthetic algae. These organisms are able to produce their energy and food on their own.
The moose and the fish are the organisms, depends on another organism for their food which means they are heterotrophs and these organisms only get 10% of the energy of what they depend on.
Plants and animals when dies or dead organic matter are decomposed by various microorganisms known as saprophytes to get their energy.

What macromolecules can be found in animal cells
and
What macromolecules can be found in plant cells
Answer:
ANIMALS: There are four major classes of biological macromolecules (carbohydrates, lipids, proteins, and nucleic acids), and each is an important component of the cell and performs a wide array of functions. Combined, these molecules make up the majority of a cell's mass.
PLANTS: The three main classes of macromolecules found in plants are thus proteins, polysaccharides and nucleic acids. However, mixed polymers are also known. such as the glycoproteins, which contain both sugars and amino acids in covalent linkage.
The macromolecules found in animal cells are carbohydrates, proteins, lipids, nucleic acids, and water. Each of these macromolecules has specific functions in the body of kingdom Animalia.
What are Macromolecules?Macromolecules may be defined as a molecule that contains a very large number of atoms that are held together by specific bonds.
The macromolecules found in animal cells are polysaccharides, proteins, nucleic acids, water, and some types of mixed polymers.
All such macromolecules perform specific functions in the structure of kingdom Plantae and meet the need for metabolic activities.

Some differentiated cells become senescent almost immediately, leaving the cell cycle and undergoing terminal differentiation. Other cells have a high need to proliferate in order to grow and repair the organ or tissue, so they do not enter senescence for a long period of time. Which cell type would be most likely to put off senescence and terminal differentiation so it could continue to replicate in order to grow and repair?
brain cells
lung cells
skin cells
heart cells
Answer:
skin cells.
Explanation:
for connexus friends
The cell that will most likely put off senescence and terminal differentiation so it could continue to replicate in order to grow and repair would be skin cells.
The skin is a tissue whose cells are constantly dividing to replace old, damaged, or worn-out cells.
Damaged, and worn-out cells are frequent on skin tissues because they directly interact with the environment, exposing them to mechanical, chemical, and other forms of damages.
Thus, the skin cells cannot afford to go into senescence or terminal differentiation due to the fact that they need to constantly divide and replace damaged ones.

Metalloids that can conduct electricity at high temperatures are
called
Metalloids that can conduct electricity at high temperatures are called semiconductors.
Semiconductors are a group of elements that have properties intermediate between those of metals and nonmetals. They have some characteristics of metals, such as being able to conduct electricity, but also some characteristics of nonmetals, such as having lower conductivity than metals.
At low temperatures, semiconductors have very low conductivity. However, at high temperatures, they can conduct electricity more effectively. This is because at higher temperatures, the thermal energy causes more electrons to break free from their atoms and become available for conduction.
One example of a semiconductor that can conduct electricity at high temperatures is silicon. Silicon is widely used in electronic devices, such as computer chips and solar cells, due to its ability to control and amplify electrical signals.
In summary, metalloids that can conduct electricity at high temperatures are known as semiconductors. They have properties intermediate between metals and nonmetals and can conduct electricity more effectively at high temperatures. Silicon is an example of a semiconductor commonly used in electronic devices.
