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.

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.

Basalt rock formed on the cooling and crystallization of magma released from volcanoes.

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.

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.

The correct answer is -  a positive feedback loop

Explanation:

Oxytocin is a peptide hormone that is released during labor in women which contracts the uterus and n increase of the oxytocin causes more release of oxytocin hormone to increase the contraction more strongly.

Oxytocin shows a positive feedback loop as its release leads to more of the oxytocin release by stimulates its more release. Most of the hormones show negative feedback release.

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.

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.

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.

Answer:

water moving from the beaker into the test tube

Explanation:

this was just on a quiz i had and it showed me the right answers after i finished

Osmosis can be used to explain the increase in fluid in the test tube that was observed after one hour.

Osmosis is the movement of water molecules through a semipermeable membrane from an area of ​​low solute concentration to an area of ​​high solute concentration. In this arrangement, the pure water in the beaker has a lower concentration of solute than the starch solution in the test tube.

Water molecules can pass through the dialysis membrane, but larger solute molecules such as starch cannot. Since the concentration of solute in the starch solution in the test tube is higher than in the water in the beaker, the water molecules move through the membrane to the beaker. This flow of water in the test tube increases the level of the liquid by increasing its volume. Therefore osmosis can be used to explain the rise of liquid in a test tube.
