Which statement about the beetles in this environment is best supported by the data?
A Green beetles are more fit for the environment than brown beetles are.
B Brown beetles undergo a greater number of unfavorable mutations than green beetles do.
C Green beetles have a greater gene frequency among their population than brown beetles
have.
D Brown beetles have a shorter life cycle than green beetles have.
The survival rate is a measure of the fitness of each species. Option A is correct. Green beetles are more fit for the environment than brown beetles are.
What is fitness?
Fitness or Aptitude can be defined as the contribution of each genotype to the next generation.
Fitness is reflected by the phenotype that results in the survival, fertility, and capability of having a mate.
It is a way of measuring the individual ability to leave fertile offspring.
Aptitude must be significant to the natural selection act in its favor.
In the exposed example we can see the survival rate of two species.
The survival rate is telling us about the fitness of each species.
The green beetle increases its survival rate (fitness) each yearThe brown beetle decreases its survival rate each yearThese results lead us to believe that the Green beetles are more fit for the environment than brown beetles are. Option A is correct.

why and how should we conserve rare plants and animals?
Explanation:
We should conserve rare plants & animals because :
It is essential for the conservation of plants. The causes of destruction of natural habitat are haphazard collection of forests products, over-grazing, clearing the forest and fire on forest. The control and proper management of these activities helps to control the natural habitat.
We can conserve them by :
Stopping hunting
Land development or making parks and reserves.
At which stage in an animal's life cycle does it form a zygote?
A. Before gametes fuse
B. After fertilization
C. After development is complete
D. Before sperm and egg cells form
Answer:
B. After fertilization.
Explanation:
It's the process where the sperm and egg fuses to form a zygote.
The term "survival of the fittest' means

Rounded rock formations with plant covering. A scientist is studying rock formations. She notices some unusual rocks like those pictured here. What can she conclude about this area? It was part of a slow underwater eruption. It was formed at a subduction zone. It is moving toward a mid-ocean ridge. It is a very young piece of land.
The rock formations are the result of the weathering of the big and large rocks by wind and water erosion. The conclusion is that rocks were part of a slow underwater eruption.
What is the formation of the rocks?Rocks can be formed due to volcanic eruptions as when the magma of the volcano rises outwards but, in the underwater surfaces, the magma can't completely rise to the outer surface and faces some pressure.
The oceanic water creates very heavy pressure on the magma of the volcanoes causing them to form some unusual structures that later solidifies into rocks.
Therefore, option A. is part of a slow underwater eruption.

Describe two integumentary system mechanisms that help regulate body temperature.
Answer:
dilation of vessels and sweating
Explanation:
The vast blood supply of the skin aids in temperature regulation: dilated vessels enable heat to escape, while constricted vessels retain heat. The blood supply of the skin regulates body temperature. The skin aids in the maintenance of homeostasis. Humidity has an effect on thermoregulation because it reduces perspiration evaporation and, as a result, heat loss.
Are most chemical reactions in living cells at equilibrium?.

For most stars, what does a higher temperature tend to go with?
O A lower luminosity
O A higher luminosity
O A red color
O None of the above
Answer:
A higher luminosity

What is a feedback loop?
Answer:
A feedback loop is the part of a system in which some portion (or all) of the system's output is used as input for future operations.
Answer: A thermostat is one example of a negative feedback loop, because when the temperature gets too high or too low, the thermostat responds in a way that returns it to its original temperature.

In which process do homologous chromosomes pair up?.
Answer: prophase I
Explanation: During prophase I, homologous chromosomes pair up and exchange sections of DNA. This is called recombination or crossing over. This is followed by metaphase I where the connected pairs of chromosomes align at the middle of the cell. After the pairs of chromosomes are aligned, anaphase I begins.
