Select the correct answer. Which statement about natural selection is true? A. Natural selection and evolution are two terms for the same phenomenon. B. Natural selection is an outdated theory to explain how evolution took place. C. Natural selection is the process by which organisms with more beneficial traits are more likely to survive and reproduce. D. Natural selection is the process by which organisms develop variation in traits, which gives them a better chance of survival.
Answer:
C. Natural selection is the process by which organisms with more beneficial traits are more likely to survive and reproduce.
Explanation:
Natural selection is an evolutional process by which species of living organisms with stronger or more beneficial traits have higher chances of survival and reproduction. In other words, it is the process by which organisms adapt and survive.
Organisms in a population are all different in their own ways. And those with characteristics or traits better suited for the environment are more likely to survive than those without. The selection prefers more beneficial traits and not wholly on the superiority of the organism. So, the survival and reproduction chance of an organism depends on the presence of traits beneficial to the environment, which is how nature selects. And in this process, those selected will dominate the population while those rejected will be reduced or even die.
Thus, the correct answer is option C.
The amount of water circulating around the planet is always
A. fixed (staying the same.)
B. decreasing.
C. increasing.
Answer:
The answer would be fixed.
Explanation:
According to the law of conservation of energy, energy cannot be created or destroyed. I can safely assume it is the same with the flow of water on the Earth’s surface. Also, according to what is known about the water cycle, it is impossible for water to simply disappear from the face of the Earth.
Let me know if I am correct! :>
Answer:
A. fixed (staying the same.)
Explanation:
The amount of water circulating around the planet is always fixed (staying the same.)

Select TWO processes that are MOST LIKELY to cause the variation in bird beak size traits within this
population
A. Asexual reproduction
B.Hibernation
C.Sexual reproduction
D.Migration
E.Mutation
The two processes that are most likely to cause the variation in bird beak size traits are ; ( C and E )
sexual reproduction ( C ) Mutation ( E )The Random Mutation occurring in birds due to the environmental factors and food availability in an area will to lead to the varying changes seen in the size of beaks of the bird within a population. long beaks are used to pick out food from cactus plants while short strong beaks are used to pick out food underground.
Sexual reproduction between birds with varying genes will lead to the formation of varying beak sizes traits seen within a given bird population.
Hence we can conclude that the two processes that are most likely to cause variation in bird beak size are ; sexual reproduction and mutation.

2. One effect of the Hedgehog gene is to make cave tetras go blind. What is another effect it might have?
Answer:
these are odd questions....
Explanation:
1. they are curious about how they get blind
2. the quills
Answer:
1.The first hypothesis is that blindness gives the tetra some sort of evolutionary advantage. That advantage might be the result of pleiotropy, which is when multiple effects are caused by the same mutation in one gene. Scientists think that the mutation that causes blindness in the tetra might also cause a "seemingly unrelated change in the fish that is beneficial."
2. Another effect it might have is to improve cave tetras' sense of smell.

Which of the following is not a possible benefit of biodiversity?
a
A higher number of species in a food web creates a more stable ecosystem.
b
A greater variety of predators indicates that fewer prey survive within the ecosystem.
c
A greater number of plant species provide more available food for primary consumers.
d
A variety of habitats within an ecosystem supports a greater number of species.
Answer:
b
Explanation:
because the more predators less prey and less organisms
It seems unlikely that biodiversity will result in fewer prey animals surviving in the environment due to the diversity of predators. So, the correct option is B.
What is Biodiversity?The variety of all living things and how they interact with one another and the environment are referred to as biodiversity. Along with species diversity both inside and between them, this also refers to ecosystem and landscape diversity.
Because it helps ecosystems function and provide services like pollination, nutrient cycling, or climate management, biodiversity is significant. For human communities, it also has significant cultural, social, and economic importance.
The range and variety of life on Earth is referred to as biodiversity or biological diversity. A measure of variation at the levels of genes, species, and ecosystems is called biodiversity.
Therefore, the correct option is B.

Which structure separates an animal cell from its surrounding environment? (1 point) 1 Golgi apparatus 2 plasma membrane 3 nuclear membrane 4 central vacuole
Answer:
2) plasma membrane
Explanation:
The structure that separates the cell from its surrounding is plasma membrane, the correct option is 2.
What is plasma membrane?The plasma membrane, also renowned as the cell membrane, is the membrane located outside all cells that distinguishes the cell's interior from its surroundings.
A cell wall is attached to the plasma membrane on the outer of the plasma membrane of bacterial and plant cells.
The semi-fluid living matter in the cell is called protoplasm or in other words simply plasm. This living matter, or one can say plasm, is contained within the plasma membrane, a biological membrane.
Lipids which are phospholipids and cholesterol, proteins, and carbohydrate groups attached to some of the lipids as well as proteins are the primary components of the plasma membrane.
A phospholipid is a sort of lipid that is created by glycerol, two fatty acid tails, and a phosphate-linked head group.
Thus, the correct option is 2.

The graph represents the distance a car travels over time while on the highway. Which statement about the car's trip is accurate?
A)
The car does not move over time.
B)
The car travels at a constant velocity.
The car's velocity increases constantly over time.
D)
The car's velocity decreases constantly over time.
Answer:
B
Explanation:
The chart is going up and up which means the car goes up and up in speed and velocity and is very consistant
The statement that is accurate regarding the car trip is that it travels at a constant velocity. The correct option is B.
What is velocity?Velocity is the pace and direction of an object's movement, whereas speed is the time rate at which an object is travelling along a path. In other words, velocity is a vector, whereas speed is a scalar value.
The rate of change of displacement is known as velocity. The rate at which velocity changes is called acceleration.
Due to the fact that it includes both magnitude and direction, velocity is a vector quantity. As the rate at which velocity changes, acceleration is likewise a vector quantity.
An object must move at a consistent speed and direction in order to have a constant velocity.
The object can only move in a straight line if the direction is constant. So, motion in a straight line at a constant speed is defined as having a constant velocity.
Thus, the correct option is B.

There is a direct relationship between the number of pollinating plants and the number of honeybees. Each population is dependent on the other for their survival and ultimately reproductive success.
Answer:
Both depends on one another.
Explanation:
Yes, there is a direct relationship between the number of pollinating plants and the number of honeybees because honeybees are insects that are responsible for pollination in the flowering plants. The population of flowering plants also has a great effect on the survival of honeybees because these flowering plants provides food in the form of nectar on which these honeybees survive and make honey from it. So we can say that both flowering plants and honeybees depends on one another for the successful growth and development.
