Which natural resource is renewable?
A. coal
B. wind
C. topsoil
D. oil
Wind is the natural resource which is renewable. Therefore, option (B) is correct.
Wind energy is considered a renewable resource because it comes from the natural flow of air masses caused by the sun and the Earth's rotation. Wind turbines turn the kinetic energy of the wind into power, and as long as there is wind, this process can keep going forever.
Wind doesn't run out like coal and oil (options A and D), which are both solid fuels. Topsoil (choice C) is an important resource for agriculture, but it can be worn down or eroded over time, making it non-renewable in the short run if it is not managed well.

Which of the following information would be most useful in determining whether 2 species are closely related?
A) There leg bones look very similar
B) The age of their bones, determined by carbon dating, is the same
C) The dna sequence found in their bones varies by only a few genes
D) The bones were found in the same layer rock
The most helpful way to determine whether two species are closely related is by comparing the appearance of their leg bones which is called as the Analogous structure. So, the correct option is A.
What is an Analogous structure?In contrast to homologous structures, analogous structures are characteristics of different species that have evolved in response to a similar environmental challenge and are similar but not necessarily in structure.
Example of Analogous structures are an insect's wings and a bird's wings are similar in structure. Although each of these species utilize their wings to fly, the origins of their wings are different.
For the aforementioned example, examining the appearance of two species' leg bones will most accurately reveal whether two species are closely related.
Therefore, the correct option is A.

What is the difference between rotation and revolution? Which one determines the planets length of day and which one determines the length of the year
Answer:
Rotation is when an item or object (specifically the earth) rotates on it's axis.
Revolution is when an item (the earth) orbits or "revolves" around another one (the sun).
The rotation of the earth determines how long a day lasts while the revolution (or orbit) determines how long a year lasts (with all of the season).

What is gene flow?
Helppppppppppp
Answer:
A the movement or organisms or their genetic material from one population to another
Answer: number 1
Explanation:
In population genetics, gene flow is the transfer of genetic material from one population to another. If the rate of gene flow is high enough, then two populations will have equivalent allele frequencies and therefore can be considered a single effective population.

Explanation:
Two related species metabolize glucose using the exact same pathways (glycolysis, citric acid cycle, oxidative phosphorylation). Experiments show, however, that species A generates only 83% of the ATP compared to species B when provided with the same amount of glucose. What could be a potential reason for this outcome
Answer:
The correct answer is - there is a 12-Carbon ring in ATP synthase of species A whereas species B contains a 10-carbon ring.
Explanation:
ATP Synthase is a protein complex that catalyzes the transfer of the protons down the gradient build by the action of the electron system in the mitochondria and makes ATP from ADP molecules.
The higher number of carbon in ATP synthase will require more protons to rotate to produce 3 ATP in this process so, if species A has more carbon present it will take more protons and able to produce only 83% of ATP compared to species B.

4. The age of the Canyon Diablo meteorite was determined by
A) carbon-14
B) uranium-235
C) hydrogen-3
D) potassium-40
Answer:
B) uranium-235
Explanation:
The age of the Canyon Diablo meteorite was determined by potassium-40. Therefore, the correct option is option D.
Before entering Earth's atmosphere, the Canyon Diablo meteorite is thought to have weighed about 300,000 tonnes. It was most likely a component of the asteroid belt that lies between Mars and Jupiter. The Canyon Diablo meteorite is frequently linked to the Asteroid 1 Ceres, one of the biggest bodies in the asteroid belt. The Canyon Diablo meteorite is notable in particular for the effect it had when it collided with the Earth's surface. The Barringer Crater, which has a diameter of roughly 1,200 metres and a depth of 170 metres, was generated by the collision.

15. What must occur in order for genetic material to be passed to cells during cell division?
A DNA replication
B RNA synthesis
C osmosis

Answer:
A
Explanation:
the process involves replication of cell's chromosomes, segregation of the copied DNA and splitting of parent cell's cytoplasm
In order for genetic material to be passed to cells during cell division, DNA replication should take place, as in Option A, and the passing of genetic contents varies between mitosis and meiosis.
What is the significance of DNA replication in cells?DNA replication is the process by which the genetic contents of a cell, the DNA, are copied which is a crucial process that occurs in all living organisms and is necessary for the maintenance of their genetic information and the transmission of this information to the next generation, it is essential for cell division and growth, as well as for the repair of damaged DNA and plays a central role in animals and plants, as new life can form and cell division takes place due to this process.

How do divisions in the geologic time scale differ from the way we organize time using a clock?
Explanation:
The Earth's geologic past is divided into hierarchical time periods. This hierarchy comprises eons, eras, times, epochs, and ages, from largest to smallest. The Cenozoic, Mesozoic, and Paleozoic Periods are the three main divisions of the Phanerozoic.
The geological timescale is the official earth clock and differs from the way we organize time using a clock, as the planet's time is too long for us to use measures of hours.
Geologic timescalePlanet Earth is about 4.5 billion years old. To better understand its history, scientists divide geologic time into five levels of classification, called chronostratigraphic units:
EonsErasPeriodsEpochsand ages.Eons are large and indeterminate spans of time and are divided into four classifications:
Phanerozoic (last 542 million years)ProterozoicArcheanand Hadean.Of them, only the Hadean is not divided into ages. The ages are characterized according to the different positions of continents, oceans and their living beings. Within the ages are divided in the periods. Epochs, in turn, are divisions within periods and are divided into ages. According to the researchers, we currently live in the Quaternary period of the Cenozoic era.
To get a rough idea of how much the existence of the human being is a mere recent episode in Earth's geological time, we use some analogies. For example, if the entire history of the planet were summarized in the twenty-four hours of a day, the existence of humanity would have occurred in the last three seconds of that same day.
Understanding the dimension of geological time and its scales of measurement becomes a fascinating mental exercise to better understand the role of man in relation to this temporality and his role as heir of all the transformations that have taken place in terrestrial space throughout the geological ages.

Answer:
Its adaptation
Explanation:
An inherited characteristic that allows an organism to better survive is called an adaptation. Thus, the correct option for this question is C.
What do you mean by Inheritance?Inheritance may be defined as a type of biological process through which traits or characters are transferred from one generation to another. It is also known as heredity.
According to the context of this question, the mechanism of adaptation involves an action of modification of an organism or its parts that significantly makes it more fit for existence or survival. This process of adaptation is passed from generation to generation, i.e. inherited from parents to offspring.
Therefore, an adaptation is an inherited characteristic that allows an organism to better survive. Thus, the correct option for this question is C.
