They eat insects which and are then eaten by raptors.
The rattlesnakes are necessary to the balance of life in a forest as they eat rodents and are eaten by owls and hawks. Therefore, option (A) is correct.
What are the characteristics of rattlesnakes?Venomous rattlesnakes belong to the genera Crotalus and Sistrurus, which are members of the subfamily Crotalinae. All poisonous snakes are snakes.
Rattlers are profoundly particular, venomous reptiles with huge bodies and triangle-molded heads. Because of their distinctive "rattle" at the tip of their tails, they are one of the most well-known groups of snakes.
Rattlers are tracked down in pretty much all aspects of the mainland US, however they're particularly normal in the Southwest. Additionally, rattlesnakes can be found in South America, Central America, and Mexico.

If a cell begins the cell cycle with 46 chromosomes, how many chromosomes will be in each of the two daughter cells produced by cell division?
Answer:
4
Explanation:
There is more genetic variation ________________ a population that ________________ populations.
Answer:
1. Within
2. Among two different
Explanation:
There is more genetic variation WITHIN a population than AMONG TWO DIFFERENT populations. This is evident in the fact that phenotypic variation occurs at a greater length within a population resulting from natural selection based on survival and the ability to produce offspring strategy. This unlike populations that consist of two or more different populations mingled together.
When during meiosis does crossing over happen?
Answer:
prophase
Crossing over occurs during prophase I of meiosis before tetrads are aligned along the equator in metaphase I. By meiosis II, only sister chromatids remain and homologous chromosomes have been moved to separate cells. Recall that the point of crossing over is to increase genetic diversity.

Describe the
relationship
between the age
of rock layers and
an unconformity
Answer:
Laws of stratigraphy help scientists determine the relative ages of rocks. This law states that deeper rock layers are older than layers closer to the surface. An unconformity is a gap in rock layers. They occur where older rock layers eroded completely before new rock layers were deposited.
Explanation:
The study of rock strata is called stratigraphy. The laws of stratigraphy can help scientists understand Earth’s past. The laws of stratigraphy are usually credited to a geologist from Denmark named Nicolas Steno. He lived in the 1600s.

identify two processes that produce the basalt
Basalt rock formed on the cooling and crystallization of magma released from volcanoes.
What is basalt rock?The extrusive igneous (volcanic) rock known as basalt is black in color, low in silica content, and relatively high in iron and magnesium.
The most prevalent type of lava rock is basalt, which forms as magma, or liquid rock, and rises from the deep Earth at volcanoes. At several of the world's active rifts now, basalt is forming, including those in Iceland, the Red Sea, the East African Rift Valley, and the Rio Grande Valley in New Mexico and Colorado.
Basalt is used in construction (e.g. as building blocks or in the groundwork), making cobblestones (from columnar basalt) and in making statues. Heating and extruding basalt yield stone wool, which has potential to be an excellent thermal insulator.

The image shows the beak shapes of four different tinches observed by Charles Darwin on the Galapagos Islands Darwin observed that broad-boaked inches
prefer to eat large, hard seeds, while finches with narrow beaks cat small, soft seeds
What did Charles Darwin infer from this study that led to the development of the Theory of Evolution?
Anches with broad breaks have Nigher survival rules than tinches with nurow beaks
Finches with narrow beaks gradually evolve broader beaks to feed on all types of seeds
The finches evolved from different ancestors with different shapes of beaks
. The finches evolved from a common ancestor and developed different break shapes to adapt to the food available
Answer:
The mechanism that Darwin proposed for evolution is natural selection. Because resources are limited in nature, organisms with heritable traits that favor survival and reproduction will tend to leave more offspring than their peers, causing the traits to increase in frequency over generations.
Explanation:
On the islands, Charles Darwin discovered several species of finches. He found out that different species of finches varied from island to island. Besides elaborating his thoughts on natural selection, this also helped him in his investigation on the evolutionary changes of the finches. Beaks changed as the birds developed different tastes for fruits, seeds, or insects picked from the ground or cacti. Long, pointed beaks made some of them more fit for picking seeds out of cactus fruits. Shorter, stouter beaks served best for eating seeds found on the ground.
Natural selection is the theory behind evolution put forth by Charles Darwin. Given the scarcity of resources in nature, animals with heritable features that promote survival and reproduction will typically produce more offspring than their contemporaries, leading to an increase in the frequency of such traits across successive generations.
Which observations about the Galapagos Islands did Charles Darwin make?He discovered a remarkable population of plants, birds, and reptiles in the Galapagos that had evolved independently of the mainland, but that frequently differed on nearly identical islands next to one another and whose characteristics he could only explain by a slow evolution of the various species.
Charles Darwin discovered a number of finch species on the islands. He discovered that several finch species vary from island to island. The Galapagos Islands are well-known for being the location where Charles Darwin discovered many previously unknown species of animals, which inspired him to develop the theories of natural selection, survival of the fittest, and evolution.

Weathering is a process in the rock cycle. How does weathering contribute to the formation of rocks?
Here are the answers
It increases the temperature and creates metamorphic rock.
It deposits sediment and forms sedimentary rock.
It breaks down rock into smaller pieces that can become sedimentary rock.
It causes lava to cool and harden into igneous rock.
Answer:
It breaks down rock into smaller pieces that can become sedimentary rock.
Explanation:
Weathering is the physical disintegration and chemical decomposition of rocks to form sediments and soils.
The process of weathering is very important for the formation of rocks because it breaks down rocks into smaller pieces.
By virtue of this, these tiny rock pieces called sediments are gathered and assembled together through erosion. They are then taken away and deposited in basins where they are transformed into sedimentary rocks. This is a very vital process in the rock cycle.!!!!Someone help me with this!!!

What type of isotopes are termed radioactive isotopes?
The radioactive isotopes of an element are called radioisotopes.
The number of protons in the atomic nuclei of different isotopes of the same element is the same, but the number of neutrons varies. The radioactive isotopes of an element are called radioisotopes. They can alternatively be described as atoms with surplus energy in their nucleus or unstable neutron-proton combinations.An isotope will become radioactive if the neutron to proton ratio exceeds a certain threshold or the atomic number is higher than 83.According to the idea, an isotope will become radioactive if its atomic number is higher than 83 or if the neutron-to-proton ratio rises over one or becomes excessively large.Gamma rays, beta particles, and alpha particles are the three types of radiation that are released. Typical instances of radioactive isotopes are Arsenic−74, Iodine−131 and Cobalt−60.learn more about radioactive isotopes here: https://brainly.com/question/18640165
