Answer:
b. energy loss in machines
Explanation:
It is an undesirable effect because it causes loss in energy in a machine which most likely requires a lot of energy to function. Therefore, it is undesirable as the machine will not function properly.
Energy pyramids show the most available energy at the base and the least amount of energy at the top. What accounts for the difference in the energy levels in these two parts of the energy pyramid?
choices:
A. Some of the energy is destroyed
B. The energy is used by decomposers
C. The energy is continually recycled in the biosphere
D. With each succeeding level, most of the energy is used by the organisms for life processes and some of the energy is "lost" as heat
Answer:
D
Explanation:
the energy from the sun is gradually lost after each level increase because the organism before being eaten uses the energy to stay alive such as staying warm or running from predators

In guinea pigs, fur length is controlled by one
gene. The Fallele generates long fur and the f
allele generates short fur. Because only one F
copy is needed to show the trait, if a guinea pig
has the FF or Ff allele combination, they will have
long fur. If they have the ff allele combination, they
will have short fur
There is a total of 4 y alleles in this populatio
There are
Falleles in the population,
There are
falleles in the population
Look at the data for a guinea pig population to
answer the following questions,
DONE
Guinea pig 1: Long fur (FF)
Guinea pig 2 Short fur (ff)
Guinea pig 3. Long fur (FF)
The fur length of the guinea pig will depend on the alleles present in the offspring, whether they are dominant or recessive.
What are dominant and recessive traits?Dominant traits are characters which are always expressed in an offspring wherever they occur.
Recessive traits on the other hand are expressed only if the dominant trait is absent in the offspring.
In the trait for fur length in guinea pig, there are two alleles for it.
F is for long fur and is dominant f is for short fur and is recessive.Thus, the possible combination of the two alles will be:
FF for long furFf for long fur andff for short furTherefore, the fur length of the guinea pig depends on the alleles present in th offspring, either dominant or recessive.

9. _______ is the pattern of behavior that follows the day/night cycle.
10. Many bird species have seasonal behaviors that cause them to _______ or change their location.
11. Explain how territorial behavior helps an animal population survive.
Answer:
Innate
fight or flight
innate
hierarchy
Aggressive
Learned
habituation
trial and error
Circadian rhythm
migrate
When animals mark their territory they ensure that the mates and food in their area are not overwhelmed. Though territorial animals often fight, it is not to the death, and more to establish social order. This prevents them from over-eating their environment and helps the entire species stay in balance to survive.

Which of the following is most affected by natural selection?
Angora rabbits

Influenza (The Flu)
Poodles
Answer:
Influenza (The Flu)
Explanation:
Influenza (the flu virus) is a real-life example of natural selection that is most evident during an annual time period when the influenza virus infection peaks. The repeated or cyclical nature of flu outbreaks is caused by the natural selection of the virus for traits that allow it to evade the immune system and replicate, a process that actually results in new distinct strains of influenza virus.

Answer:

Explanation:
The weathering that most likely played the largest role in creating the cliff was when water in the river broke down the rocks into smaller pieces, which is present in Option B.
What is the weathering process?Rock cliffs can be formed by a variety of weathering processes. One common process is erosion caused by the movement of water as seen here as water flows through the mountains. Over time, these agents of erosion can wear away the softer layers of rock, leaving behind the harder layers that form the cliffs. Physical weathering is caused by the action of natural forces such as water, wind, etc. For example, water can flow into cracks in rock and then freeze and expand when the temperature drops, causing the rock to break apart. Wind can also erode rock surfaces over time by carrying small particles of sand and other debris that scrape and wear down the rock.
Hence, here the largest role in creating the cliff was when water in the river broke down the rocks into smaller pieces, which is present in Option B.

Natural selection requires there to be a variation of alleles in a population. What mechanism best describes how new alleles are formed in a population
Answer:
Natural selection does not create adaptions, mutations, or variations. Natural selection causes the extinction of individuals who are not well adapted to changes in the environment. Natural selection can also provide reproductive advantages for some individuals over other individuals.

The fibrocartilage pad between the medial condyle of the femur and the medial condyle of the tibia is called the __________.
Medial meniscus are fibrocartilage attached to the tibial collateral ligament, that is, between the medial condyle of the femur and the medial condyle of the tibia.
What is medial meniscus?It is an articular fibrocartilage that extends medially across the knee joint, where it attaches to the tibia anterior to the insertion of the anterior cruciate ligament.
This in the middle zone has continuity with the deep portion of the medial ligament, being well attached to the tibia and femur and acting as a cushion and distributing the weight of the femur.
Therefore, we can conclude that the medial meniscus are fibrocartilage attached to the tibial collateral ligament, that is, between the medial condyle of the femur and the medial condyle of the tibia.
