Under certain external conditions, a person will perspire a great deal. For which internal condition does this response primarily provide homeostasis?
Answer:
Abnormally high temperature
Explanation:
Sweating or perspiration is a homeostatic response to abnormally high body temperature. Evaporation of the sweat causes cooling of the body and this causes the temperature of the body to return back to normal.
When the setpoint temperature of the body is breached by being too high, the negative feedback mechanism kicks-in, and the sweat glands of the skin becomes activated. The body sweats, and the evaporation of the sweat from the surface of the skin causes cooling and a return back to the setpoint.
how can evolution lead to reproductive success?
Answer:
Evolution in humans is happening spontaneously and the development of species can improve the capability of offspring and the intelligence of species. All animals today are evolutionary, we came from bacteria to being are millions of times the size of that organism with millions of years going through evolution. We have gone from splitting our cells to make more, to creating life to another to do the same.

7.) DURING THE FIRST ERA, THE __________ ORGANISMS EVER ON EARTH WERE
ERA, THE FIRST LIVING
Answer:
The first living organism on Earth are Bacteria in the first era.
Explanation:
Bacteria are the first organism to leave be on Earth. They came into existence about 3.5 billion years in the first era in the waters of small oceans. Then there were anaerobic hetetrophic bacteria because the atmosphere was free of oxygen before. Cyanobacteria then became the first autotrophic organisms and first photosynthesizer that release oxygen to the atmosphere after photosynthesis.

Microfilaments are a component of a cell's cytoskeleton and are made of the protein actin. They are important for giving a cell its shape and also aid in _______.
A.) Protein synthesis
B.) Cellular movement
C.) DNA replication
D.) Energy conversion
Microfilaments are a component of the cell's cytoskeleton and these are made up of the actin protein. They are involved in the cellular movement. Thus, the correct option is B.
What are Microfilaments?Microfilaments are also called as actin filaments, as they consist of two intertwined strands of a globular protein, which is known as actin protein. In association with myosin, microfilaments help to generate forces that are used in cellular contraction and cellular movements. During cell division, these filaments results into dividing cell to pinch off into two daughter cells and are involved in amoeboid movements of certain types of cells.
Microfilaments assist with cellular movement due to the presence of actin filaments. Actin filament works with another protein called myosin to produce muscular movements, cell division, and cytoplasmic streaming during cell division. Microfilaments keep the organelles in place within the cell.
Therefore, the correct option is B.

A frog that is dominant for its light green color mates with a brown frog and produces one small brown frog. How is this possible if the green color is dominate?
Answer:
The dominant (light green) parent was heterozygote for the trait
Explanation:
According to Gregor Mendel in his law of dominance, an allele is said to be DOMINANT if it masks the phenotypic expression of another allele in a gene. The allele being masked is called RECESSIVE allele. In this case of a frog whose allele for light green color is dominant over the allele for brown color, the light green color allele (G) is dominant while the brown color allele (g) is recessive.
However, in a cross between that have light green frog and a brown frog, a small brown frog is produced. This is possible despite the green color being dominant because the genotype of the light green dominant parent is HETEROZYGOUS i.e. it contains both light green (dominant) allele and brown (recessive) allele.
Hence, when a gamete with recessive allele (g) is produced by the heterozygous light green frog (Gg), it mates with a recessive allele from the brown frog (gg) to produce a brown offspring (gg).

A mountain climber climbs to the summit of a 7 km mountain and then returns to his campsite located at the base of the mountain. Explain what happens to the temperature and pressure as he ascends to the summit and returns to his campsite.
Answer:
Temperature reduces and pressure increases as he ascends to the summit while the reverse of this happens when he returns to his campsite
Explanation:
When a person climbs a summit, the pressure increases but the temperature reduces. but as he returns to his campsite the normal temperature and pressure are regained which means the pressure reduces and the temperature increase.
The temperature and pressure decreases as he ascends the mountain and increases as he descends the mountain.
We know that temperature and pressure decreases with altitude. In fact, the temperature decreases by 6.5°C for every 1000 meters increase in altitude. Hence air pressure decreases with increasing altitude.
Hence, for a mountain climber, the temperature and pressure decreases as he ascends the mountain and increases as he descends the mountain.

Alejandro wants to find the speed of his car in meters per second. His car traveled 50 cm. It took 5 seconds to travel 50 cm. How fast did his car go?
Answer:
0.1m/s
Explanation:
Speed can be calculated using the formula;
Speed (m/s) = distance (m) ÷ time (s)
According to the information provided in this question, Alejandro's car travels 50cm in 5seconds i.e. the distance traveled is 50cm and the time is 5s.
However, the question requires the distance to be in metres (m). We, therefore, need to convert 50cm to m by dividing by 100.
100cm = 1m
50cm = 50/100
= 0.5metres.
Speed = 0.5/5
Speed = 0.1m/s.
The car travels as fast as 0.1m/s.

Shear stress is the result of two parallel forces moving in opposing directions to each other. It is the force that results in two slabs of rock sliding past one another.

A forest fire will effect which Earth system?
Answer:
geosphere
Explanation:
Answer:
Look down!! ;)
Explanation:
Pollutants produced from the burning such as CO2 will enter the atmosphere. The geosphere could be affected due to the intense heat can cause rocks to break apart/ erosion. The biosphere is greatly impacted from the fire. Vegetation is killed which in return negatively impacts the wildlife in the forest.
