Answer:
There are two types of succession.
Primary Succession - A bare mass of rock developing an ecosystem from scratch. It will use lichens and moss to create soil... a good example of this is a new land mass formed by a volcano.
Secondary Succession - A environment and ecosystem that was destroyed but does not need to start from scratch. It just needs the plants to regrow and attract wildlife back again... a good example of this is a forest destroyed by a wildfire.

New technology is important to the development of theories because it
allows for repeated experimentation.

replaces theories that are old and hard to test.
provides a new way to acquire new information.
Answers
New technology is important to the development of theories because it provides a new way to acquire new information. With new technology, researchers can collect data in new and more precise ways, which can lead to new insights and discoveries. It can also allow for the testing of existing theories in new ways or under different conditions, leading to a better understanding of the phenomena being studied. However, the importance of technology in developing theories does not necessarily mean that it replaces old theories or allows for repeated experimentation on its own. Theories are typically developed through a combination of empirical evidence, experimentation, and theoretical modeling, and the role of technology is to provide new tools and methods for gathering and analyzing data.
Check all that are true of the following scenario.
An archer strings an arrow on a bow and draws the string back. Aiming the bow
upwards at a 45 degree angle, the archer pauses with arms locked into position and
then releases the string. The arrow flies upwards making an arc and then sticks into
the trunk of a tree with an audible thud.
At least four different types of energy are illustrated in this example.
The first energy transformation in the scenario is chemical energy to kinetic.
From the time the archer draws the bow until the thud us heard, entropy increases in
the universe.
The energy of the arrow at the end of the scenario is equal to the energy exerted by the
muscles of the archer.
When the arrow sticks into the tree the original energy has all been used up.
Answers
Statements 1 and 3 are true, while statements 2 and 4 are false.The first energy transformation in the scenario is chemical energy to kinetic. - True.
The archer converts chemical energy stored in their muscles into kinetic energy when they release the string and propel the arrow forward.From the time the archer draws the bow until the thud is heard, entropy increases in the universe. - False. Entropy is a measure of disorder or randomness in a system. In this scenario, the archer's actions do not necessarily lead to an increase in entropy.
The energy of the arrow at the end of the scenario is equal to the energy exerted by the muscles of the archer. - False. Energy is conserved in a closed system, but some energy is lost as heat and sound during the process. Therefore, the energy of the arrow at the end may be less than the energy exerted by the archer's muscles.
When the arrow sticks into the tree, the original energy has all been used up. - False. Energy is not created or destroyed but rather transformed from one form to another. Some of the initial energy from the archer's muscles is transferred to the arrow's kinetic energy, but it is not entirely used up.In summary, statements 1 and 3 are true, while statements 2 and 4 are false.

which item would be most appropriate to measure on the triple beam balance in the gizmo
Answers
Answer:
ok, here is your answer
Explanation:
AI-generated answer
The triple beam balance is used to measure mass, which is the amount of matter in an object. Therefore, any item that needs to be measured in terms of its mass can be measured using the triple beam balance in the Gizmo. Some examples of items that can be measured using a triple beam balance are:
- Solids such as rocks, metals, and minerals
- Liquids such as water, oil, and alcohol
- Powders such as flour, sugar, and salt
To measure an item on the triple beam balance in the Gizmo, place the item on the pan and adjust the riders on the beams until the pointer is at zero. Then, move the riders along the beams to find the mass of the item. Make sure to read the mass from left to right, starting with the largest beam and moving to the smallest beam.
In summary, the most appropriate item to measure on the triple beam balance in the Gizmo is any item that needs to be measured in terms of its mass.
mark me as brainliestthe scottish fold is a breed of cat with a mutation in a gene involved in cartilage development. the result is that each ear of the cat has a crease, so the ears fall forward and lie against the head instead of standing up like the ears of most small cats. the mutation is a dominant allele.
a cat that is heterozygous for the fold allele mates with a cat that is homozygous for the fold allele.
what are the expected percents of offspring that will have each characteristic?
Answers
In complete dominance, the presence of at least one dominant allele in the genotype is enougth to express the dominant phenotype. 100% of the offspring will have mutated creased ear, while 0% of the will have normal standing ear.
What is complete dominance?
Complete dominance is the inheritance pattern in which the dominant allele completely masks the recessive allele.
This interaction between alleles is observed in individuals who are heterozygous for a particular gene. They carry both alleles but only express the dominant trait. The dominant allele is hiding the expression of the recessive allele.
In the exposed example,
E is the dominant allele and codes for the mutated creased ear,e is the recessive allele and codes for the normal standing ear.Cross: a cat that is heterozygous with a cat that is homozygous for the fold allele.

ow does the thermal energy of the liquid in both of the graduated cylinders differ
Answers
Answer: Matter can change from one state to another when thermal energy is absorbed or released. ... heated, it absorbs thermal energy and its temperature rises. At some point, the temperature stops rising and the ice begins to change into liquid water. The change from the solid state to the liquid state is called melting. The molecules move around very little and have a low amount of energy. ... Molecules in a liquid have more energy than molecules in a solid. And if you heat it up even more, the molecules will speed up so much that they won't be stuck together at all. The molecules in the gas have the most energy. Solid particles have the least amount of energy, and gas particles have the greatest amount of energy. The temperature of a substance is a measure of the average kinetic energy of the particles. A change in phase may occur when the energy of the particles is changed. There are spaces between particles of matter.

Explanation:
A common method for analyzing microtubule motor activity is to attach them to a glass coverslip (the tails stick very well to glass) and then incubate with microtubules, which will settle on them and then "glide" across the surface of the coverslip as the heads of the motors propel them. This is easily observable in the light microscope. In an assay such as this, how can one determine the directionality of the movement of the microtubules (plus- or minus-ended)? Assume that you do not know if the motor is a plus- or minus-end motor prior to the experiment.
Answers
Answer:
Explanation:
Microtubules are integral part of the cytoskeleton of eukaryotic cells, responsible for maintaining the shape of the cell. They are involved in intracellular trafficking by forming veritable "rails" along which motor proteins move and transport various organelles.
In analyzing microtubular motor activity, the plus (+) end and the minus(-) end proteins can be marked with non-identical fluorescent proteins, followed by observing it under the fluorescent microscope. From observation, the presence of motility of the fluorescent dye helps to determine if the motor is plus or minus end.

An apple, potato, and onion all taste the same if you eat them with your nose plugged
WHY IS THIS
Answers
Answer:without your nose you taste
Explanation:
use book
This is because most of what we perceive as “taste” is due to our sense of smell. Our brain combines the information from both scent and taste to create the overall flavor of food or drink. When we plug our nose, we block our sense of smell and impair the connection between our nasal cavity and brain. This makes it hard to identify the flavor of food, which consists of smell, taste, temperature, texture, spiciness, and so on. Therefore, apples potatoes and onions may taste similar if we eat them with our noses plugged.

What is mitosis?
Mitosis is a cell division process through which a diploid somatic cell (2n), produces two identical daughter diploid cells (2n).
During mitosis, the whole-cell first suffers duplication of its content and then it separates. Mitosis occurs in somatic cells and in germ cells.
In this example, we can see
One cell with two chromosomes (step 1). This cell duplicates its content, and now each chromosome is composed of two chromatid sister (step 2). Chromosomes move to the equatorial plane where they align (step 3) and then each chromatid separates from the sister chromatid and moves foward one of the cell poles (step 4). The cell divides and the two resulting cells have two chromosomes, just as the parental cell (step 5)A) This model results in two identical daughter cells.
B) This model shows asexual reproduction.
