heart muscle cells have alot of mitochondria. why do you think this is?
Answer:
The heart is a vital organ with a high metabolic demand. Our heart muscles contain so much mitochondria because those muscles are very active in our body and require lots of energy to constantly pump blood through our circulatory system.

Answer:
Educate them and show the benefits of sustainable resources
Explanation:
How would cellular homeostasis be immediately affected if the cell did not have Golgi bodies?
Lysosomes would not be able to break down wastes as there would be no products being produced by the cell.
Vacuoles would not have material to store because water and other materials would not be able to enter the cell.
Proteins would not be able to be made because the ribosomes would not have the instructions they need to produce them.
Organelles would not receive the products they need to function and materials that were made within the cell would not be able to leave the cell for use.
Answer:
The correct answer is - Organelles would not receive the products they need to function and materials that were made within the cell would not be able to leave the cell for use.
Explanation:
In the absence of the Golgi apparatus, there would be many changes and negative impact would be on the cell such as lysosome would be lacking also and digestion would not be possible. Golgi apparatus functions as the modifying agent of protein and lipid that come from ER and transport them out of the cells to the desired organ.
The modification and transport of lipid and protein produced would be stopped and might float in the cytoplasm. If the particular organ does would not get the hormone, lipid molecule or particular enzyme, the organ will fail to do its function and homeostasis of organism would be affected.

Answer:
Algae has the most energy.
Explanation:
===================================================================
This is because it starts off at the bottom of the chain/level and is like a plant, which gets its energy from the sun.
Plants usually have the most energy in the trophic level, so in this case, its Algae.
When the organism is passed down the trophic levels, the energy gets cut (I forget the amount, it might be in half), so the Shark has the least among of energy in the trophic levels.

How does biodiversity reduce one species’ dependence on another species? Explain, and provide an example.
Answer:
For example, two animal predators may consume different prey items, so they are less likely to compete with one another, allowing higher total biomass of predators in the system. In the case of plants, all species may utilize the same suite of resources (space, light, water, soil nutrients, etc.)
Explanation:
The presence of large biodiversity can reduce one species dependence on another species as it provides resources such as food which will reduce the chances of a species to become threatened.
What is biodiversity?Biodiversity can be defined as the variety of all the different kinds of organisms such as the plants, animals, insects and microorganisms which live on the planet.
A large biodiversity is helpful for the species as it increases the stability of the ecosystems. This is possible because it reduces the dependence of one species on another, for the instance for food. For example, if a species has only one food source, it may be easily threatened by the environmental changes. However, if many species similar to it are present in the ecosystem then the chances of the species to become threatened are very low.

HI AGAIN! HELP!!!
All living things need energy to survive. The most common source of energy for organisms is glucose molecules, which are used as food. A plant’s food is no exception. Where do plants get the carbon needed to make glucose molecules during the process of photosynthesis?
from the ground.
from the air.
from the water.
from the sun.
Answer:
the air
Explanation:
Plants get the carbon from the air which are needed to make the glucose molecules during the process of photosynthesis in plants. Thus, the correct option is B.
What is Photosynthesis?Photosynthesis is the process of formation of carbohydrate (sugar) in the green leaves of plants. This process takes place in the presence of light. In this process, the light energy (solar radiation) is trapped in the chlorophyll pigment present in the green leaves of plants, this energy is converted into chemical energy in the form of glucose (carbohydrate) which is used by the plants in various processes.
The reaction includes the reaction between carbon dioxide and water molecules which are present in the air to produce glucose and oxygen gas which are consumed as food and in the process of respiration.
Therefore, the correct option is B.

An environmental toxin is discovered that interferes with certain
cellular functions. When affected cells are examined, it is observed that
proteins that are normally found on the plasma membrane are instead found in
the cytoplasm. Other proteins are also located improperly. Which structure is
most likely affected by the toxin?
A
lysosome
B mitochondria
С
cell wall
I
D
Golgi apparatus
Answer:
Golgi apparatus
Explanation:
The Golgi apparatus is an organelle found in most eukaryotic cells, i.e. cells with a clearly defined nucleus. The purpose of the Golgi apparatus is to transport, modify, and package proteins and lipids. If a cell affected by an environmental toxin ended up with misplaced proteins, we could conclude that the organelle that is no longer functioning properly is the Golgi apparatus.

How is biodiversity regulated in a system?
Answer & Explanation:
Biodiversity is regulated primarily by weather in addition to many other factors. Weather changes can cause droughts or flooding. Weather often pushes main species to migrate and therefore cause new biodiversity, indirectly the migration of one species into a new region could cause that new species to consume the already thriving species already in existence which then could reduce the value of species diversity in that region and throw off the pre-existing ecosystem.
What would happen to an animal cell with an internal salt concentration of 0.8%
if it were placed in a salt solution with a concentration of 20%?
A. Not enough information to be able to tell
B. The cell would swell and burst
C. The cell would not be affected
D. The cell would shrink
Answer: The cell would swell and burst, because the 0.2% salt solution is hypotonic with respect to the cell, causing a net movement of water into the cell.
Explanation:
An animal cell with an internal salt concentration of 0.8% will shrink if it were placed in a salt solution with a concentration of 20%.
OSMOSIS:
Osmosis is the movement of water molecules from a region of higher concentration to a region of lower concentration via a semipermeable membrane. Movement of water in osmosis is based on concentration gradient i.e. difference on concentration of solute inside and outside the cell. Water will move from a cell with more water or less salt concentration i.e. the internal cell with 0.8% salt concentration to a solution with less water or more salt concentration i.e. 20% salt concentration. This will cause the cell to lose water to its external solution, and, hence, shrink.Learn more about osmosis at: https://brainly.com/question/264225?referrer=searchResults

"The swamps and marshes of coastal Louisiana are among the Nation's most fragile and valuable wetlands, vital not only to recreational and agricultural interests but also the State's more than $1 billion per year seafood industry.What part of Louisiana is most in danger from land loss?
Dozens of reports show the highest rate of land loss occurred in areas with the heaviest amount of oil and gas extraction and canal dredging, Marshall says. According to some studies, the oil and gas industry is responsible for anywhere between 36 to 60 percent of the loss.
Answer:
Natural factors that can cause the loss and gain of wetlands in Louisiana are hurricanes, drought, salt water moving inland, subsidence, and rise in sea levels.
