Answer:
modeling
Explanation:
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.

What are the FIVE ways an object's motion can change?
Answer: An object's motion can change physically by humans, Physically by humans The action from a force can cause an object to move or can speed up accelerate, to slow down (decelerate), to stop, or to change direction. Since any change in velocity is considered acceleration, it could be said that a force on an object results in the acceleration of a object.
Explanation: please can I get brainliest
Motion is defined as the phenomena where an object moves from one point to another. Usually, a force has to act on the object for it to be in a state of motion.
Mathematically, motion has to do with:

When women are in labor, the uterus contracts more and more strongly by the actions of a peptide hormone messenger. This scenario is an example of.. * 1 point a negative feedback loop. a positive feedback loop. signal transduction immediately changing gene expression in its target cells. the key role of the anterior pituitary gland in regulating uterine contraction.
Answer:
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.

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.
Help!!!! Can anyone answer this lab questions below about mitosis!!!!
Answer:
Mitosis is a division of a eukaryotic cell in which the chromosomes are evenly distributed among the daughter cells.
In multicellular organisms, both sexual and asexual reproduction is followed by cell division, which ensures the growth and development of the organism. In addition, cell division is necessary to replace dead cells and repair injuries. New cells are constantly being added and old ones are being destroyed. About a hundred thousand more cells are created every second, and of course the same number dies. The new cells start with the division of the source cell. The cells formed in this way are called daughter cells. Stem cells can gradually divide into all the different cells in the body through mitosis.
Most of the body's cells are constantly renewed by mitosis, but there are also so-called irreplaceable cells that are formed only once in a lifetime for the life of the organism and do not regenerate by mitosis.

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.

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.

Answer:
A groundwater system comprises the subsurface water, the geologic media containing the water, flow boundaries, and sources (such as recharge) and sinks (such as springs, interaquifer flow, or wells).
Explanation:
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.

The rise of the liquid in the test tube that was observed after one hour can be explained as a result of the *
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.
