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

The musk ox has a large body size and small appendages. How do these characteristics enable it to survive in the tundra?
Answer:
The large body size and small appendages of the musk ox help minimize its heat loss. The smaller the surface area of an animal compared to its weight, the more slowly it loses heat.
Explanation:
The large body size and small appendages of the musk ox helps them to minimize heat loss from the body. The smaller the surface area of an animal compared to its body weight, the more slowly it loses the heat which keeps them warm for longer durations.
What is adaptation?An adaptation is defined as any change in physical or behavioral feature of an animal which helps them in better survival in the environment in which they live. In other words, an adaptation is something an organism does with their bodies which helps them in finding food, water, mates, and shelter which increases the chances of survival.
Musk ox can survive on an extremely spare diet of tundra plants, such as dried grasses, sedges and willows of forests. In the winter, when the temperature of Tundra decreases further the Musk ox can maintain their body temperature and survive in these extreme conditions. The larger body size and small appendages of these animals reduce the loss of heat from the body.

The forest at Great Smoky Mountains National
Park is sick, infected by invasive bugs and
plants. Matt Moore, Kaleb Lique Naitove and
Emily Baird of the National Park Service are
some of the field medics trying to keep it alive.
…
The forest they walk through is mesmerizing. The
trees glow green in the Tennessee sun. There
are a lot of tree species in this forest, but the
one they’re looking to treat is an Eastern
hemlock, an evergreen conifer that ranges
from Canada to northern Mississippi. Hemlocks
make up a significant portion of a lot of forests
in the eastern U.S., but particularly so in Great
Smoky Mountains National Park.
…
‘A Tsunami Wave’ Of Adelgids
After about 20 minutes of hiking off-trail in
the park, Moore and company reach the tree
they’ve been looking for. It’s tall, but not
particularly big. You could wrap your arms
around its trunk and still clasp your hands. By
all outward appearances, it’s healthy.
It’s time for the crew to start helping the tree
by injecting it with pesticide. Moore drills holes
around the tree’s base and then Lique Naitove
and Baird attach tubing. A bicycle pump
connected to the tube system begins to fill
it and then the base of the tree with the red
pesticide.
The female wooly adelgid is miniscule, attaching herself to the hemlock’s needle after creating her ova sack, as
shown above.
To Tame A ‘Wave’ Of Invasive Bugs,
Park Service Introduces Predator
Beetles

It’s called a tree injection system. “We call
them IVs,” Webster says. “They’re out doing
a tree IV.”
It’s like a flu shot that will help the tree ward off
invasive bugs. Most of the trees Webster’s crew
treat just get sprayed with pesticides that have
the same effect. This one’s different because
it’s near a stream and the crew doesn’t want
pesticides getting in the water.
They can’t do it for all of the trees they
treat because there are just too many. The
vegetation crew here has treated more than
a quarter million trees in the Great Smoky
Mountains. The treated ones, like the one they
hiked to, are easy to spot because they look
healthy and are alive. The trees that weren’t
treated are probably dead “or they’re close
or on the way out very soon,” Webster says.
“Probably in the next 10 years.”
The reason for this die-off is the hemlock
woolly adelgid, which is native to Asia.
Scientists believe that the specific kind killing
the Eastern hemlock is from southern Japan.
Adelgids were first discovered in the U.S. in
the 1920s. They were transported overseas
by humans and continue to be spread with
human help, mostly through the purchasing,
selling and transporting of firewood. Today,
the hemlock woolly adelgid is established in
16 states, from Maine to Georgia.
The trees at Great Smoky Mountains National
Park have been infested with adelgids
for longer than a decade. With no natural
predators and no evolved defenses, the
adelgids swept through the hemlocks at the
park like “a tsunami wave,” Webster says.
Many of the park’s hemlocks died quickly;
others are dying more slowly.
…
A Predator-Prey Balance
The pesticide treatment that the park’s
vegetation crew uses doesn’t get rid of the
hemlock woolly adelgid. It protects the tree
that gets it and only lasts five to seven years.
“It’s a stopgap solution,” Webster says.
Because of that, the National Park Service and
scientists have been trying a longer-lasting
one: predator beetles. The hemlock woolly
adelgid, like most invasive species, thrives in
its new environment because it doesn’t have
any natural predators. To change that dynamic,
Great Smoky Mountains National Park has
brought in a few species of predator beetles
from Asia that they’re raising at insectaries, or
nurseries for bugs.
…
Predator beetles will never eradicate the
hemlock woolly adelgid. They’re here to stay.
The hope of the Park Service is that by creating
that balance between predator and prey and
by educating people to not move firewood
from one location to another, they can slow
the spread of the adelgid enough to give
the remaining Eastern hemlocks a chance to
survive and adapt.

How do speed and direction affect velocity?
Answer:
Forces affect how objects move. They may cause motion; they may also slow, stop, or change the direction of motion of an object that is already moving. Since force cause changes in the speed or direction of an object, we can say that forces cause changes in velocity. Remember that acceleration is a change in velocity.

The volcanoes can be seen on the topographic map as tall peeks. How many volcanic peaks higher
than 7000 feet can be seen on this map.
Answer: 2
Explanation:
Each line represents an increase in height of 1000ft.
And the volcano peaks are the circles with no other concentric lines inside (meaning that does not grow anymore, so it is the peak).
We can see that the peak of the top volcano has 13 lines, so it is around 13,000 ft high.
The bottom volcano has also 13 lines, so it is also around 13,000 ft high, then in the image we can see two volcanos higher than 7000ft.
component of a phospholipid?
Answer:
Phosphate group headTwo fatty acid tailsExplanation:
A phospholipid is made up of a phosphate group head and two fatty acid tails. They are connected by a molecule of glycerol.
To form cell membranes, phospholipids line up with their hydrophilic (water loving) heads on the outside of the cell and their hydrophobic (water hating) tails inside.
A second layer of phospholipids forms with the heads facing inside the cell and tails facing away. This forms a double layer - with the phosphate group heads on the outside, and fatty acid tails on the inside. This double layer, called a lipid bilayer, forms the cell membrane.

What happens to the glucose produced in photosynthesis? Select ALL that apply a The glucose is modified & stored in the plant for later use b The glucose is used directly as energy by the chloroplast c The glucose is moved to the mitochondria where it will be converted into energy d The glucose is released as a waste product
Answer:
The glucose produced in photosynthesis is altered and processed for later use in the plant. The glucose is used directly by the chloroplast as energy. The glucose is transferred to the mitochondria to be transformed into energy.
Explanation: Among the four statements, three of the statements are correct . The fourth statement which states that "the glucose is released as a waste product " is incorrect . This is because oxygen is used as the waste product rather than glucose.
All the three statements are correct about glucose in photosynthesis . The plant uses glucose, with most of it transformed into other carbohydrates, such as starch and cellulose.
A mechanism in which, in the mitochondria of all cells, chemical energy (glucose) is converted into an energy currency (ATP). Glucose and oxygen are converted into water and carbon dioxide. There are two forms namely, aerobic which requires oxygen and Anaerobic which does NOT require oxygen.
Photosynthesis is the process of preparing food in the presence of sunlight, water, and carbon dioxide to make glucose and release oxygen.
The use of glucose produced during photosynthesis is:
a. The glucose is modified & stored in the plant for later use
b. The glucose is used directly as energy by the chloroplast
c. The glucose is moved to the mitochondria where it will be converted into energy
Glucose pathway in plants:
Glucose is the primary source of energy, which is stored in the form of starch. The glucose is broken down through cellular respiration to yield ATP. Glucose is directly used as a source of energy by chloroplasts. Chloroplasts require glucose to convert light energy into chemical energy to carry out photosynthesis. Mitochondria are the powerhouse of the cells, which converts glucose into ATP via cellular respiration. The glucose and oxygen are converted into water and carbon dioxide.To know more about the roke of glucose in photosynthesis, refer to the following link:

In a short essay (100–150 words), explain how oxidative phosphorylation—the production of ATP using energy derived from the redox reactions of a spatially organized electron transport chain followed by chemiosmosis—is an example of how new properties emerge at each level of the biological hierarchy.
Answer:
Oxidative phosphorylation is the main process that takes place in the mitochondria to produce ATP by the series of various carriers from NADH or FADH2 to Oxygen molecules. This involves a spatially organized electron transport system in form of a chain of the redox reactions.
The properties that emerge occurs only when there is two or more part of the chain work together and not individually. If all the part such as various part of ETC or ATP synthase and the membrane of the organelle all together workes in an orderly manner then only ATP will be formed by producing H+ protein.
