Answer:
Because they are hydrophobic
Explanation:
The image shows a cell membrane, which is made up a phospholipid bilayer. The phospholipid bilayer is made up of a phosphate head, which is hydrophillic, and fatty acid tail, which is hydrophobic. That means they are repelled by water.
Because the tails are hydrophobic, they are repelled by the water towards one another, while the heads remain facing outwards,

Answers
The organelle that would you expect to find in plant cells but not in animal cells is chloroplasts, second option is correct.
What is chloroplast and its function?Through the processes of photosynthesis and oxygen release, chloroplasts provide energy that supports plant growth and crop yield. As a result, active substances such amino acids, phytohormones, nucleotides, secondary metabolites are produced by chloroplasts.
Organelles found in plant cells called chloroplasts use the photosynthetic process to change light energy into relatively stable chemical energy. They maintain life on Earth in this way. For plant cells, chloroplasts also perform a variety of metabolic processes, such as the creation of fatty acids, membrane lipids,

Each year, the United States' federal costs exceed the anticipated national budget. In fact the last time that the United States government was able to end a fiscal year without accruing more debt was in 1960. This means that due to excessive spending and compounding interest accrued, the United States' national debt has escalated astronomically over the past several decades. The table shown below lists the recorded U.S. national debt amounts, written in standard form, for each decade, from 1960 to the year 2010.
Year U.S. national debt (in U.S. dollars)
1960 $286,330,760,848.37

1990 $3,233,313,451,777.25
2000 $5,674,178,209,886.86
2010 $13,561,623,030,891.79
For each decade, convert the U.S. national debt amount to a number in scientific notation, rounded to the nearest hundred millions dollars. Enter in numerical answers only.

How do limiting factors determine the carrying capacity of an ecosystem ?
Answers
Answer:
Limiting factors determine carrying capacity. The availability of abiotic factors (such as water, oxygen, and space) and biotic factors (such as food) dictates how many organisms can live in an ecosystem. Carrying capacity is also impacted by the availability of decomposers.
Explanation:
Carrying capacity is determined by limiting variables. Limiting factors can be divided into two categories: those that depend on the density and those that don't.
What are the limiting factors?Limiting factors can be divided into two categories: those that depend on the density and those that don't. These names are accurate in their meanings.
No matter how big or little, expanding or contracting, the population is affected by density-independent causes. For instance, regardless of the density of any one population, a wildfire that burns through a dense forest in the Everglades has a significant effect on every population in the area.
The majority of density-independent limiting variables fall into the abiotic (nonliving) group, which includes wildfire. Hurricanes, pollution, and seasonal climate extremes are other density-independent variables.
Therefore, Carrying capacity is determined by limiting variables. Limiting factors can be divided into two categories: those that depend on the density and those that don't.

This means that we as humans can learn with every mechanism that has been developed through millions of years and apply to our self been.
Answer:
all of these
Explanation:
The preservation of the biodiversity of the Earth is important for many ecological, economic, and cultural reasons.
Biodiversity increases ecosystem stability for a given type of ecosystem because greater species diversity ensures natural sustainability of all life forms within the ecosystem. Ecosystems are also highly interconnected and the removal of even a few species can cause ecosystem disruption.
The organisms of Earth's ecosystems provide services that humans cannot replicate. These ecosystem services include the generation of soil that is typically done by microbial and animal species, the maintenance of air quality that is done by plants, the decomposition of wastes that is done by the Earth's decomposers, and the maintenance of water quality that is done by wetland ecosystems.
