A physical change is a type of change in which the form of matter is altered but one substance is not transformed into another.
Answer:
D.
Explanation:
If it is just a physical change then we can instantly cross out B. and A. as they say in there that they become a new substance and that is not just a physical change. C. is not correct because they combine and there for make a new substance. That leaves D. which makes sense because a physical change would be a change in its size or something that doesn't change the material, this is like when you break a rock, it is now in pieces and smaller but it is still the same rock therefor it is a physical change.
Birds share many similarities with a certain group of dinosaurs that includes the Tyrannosaurus Rex and the Velociraptor. Like birds, these dinosaurs had hollow bones and scales. Fossil evidence shows that many had feathers and some could fly. Evidence also suggests these dinosaurs were warm-blooded.
Given the similarities, identify one characteristic that could be used to differentiate birds from dinosaurs.
Answer:
Size
Explanation:
Dinosaurs, based on recent studies show that they were larger animals and its not possible now for a bird to be the same height or weight as a dinosaur back then
Birds and dinosaurs have found to share many similarities such as presence of feathers, laying eggs, warm blood however the size difference is the main differentiating characteristic between the two.
What are evolutionary links?Different species are related to each other and are gradually undergoing change over time. Evolution in a population affects the physical characteristics of an organism. The ancestors and links between two species can be found with the help of evolutionary links.
The features or evolutionary links between birds and reptiles i.e., dinosaurs are walking on two legs, having feathers, laying eggs, warm bloodedness. All these traits are inherited features from dinosaurs. The difference between dinosaurs and birds is in the size of their body and absence of scales on the birds body.

PLZ thank and five star
and a brainliest would be nice:-)
Answer: D. the amount of space something takes up
============================================================
Explanation:
For example, if you have a 2 inch by 3 inch by 5 inch rectangular block, then the volume it takes up is 2*3*5 = 30 cubic inches. We can fit 30 smaller unit cubes in this 2 by 3 by 5 block.
Another example of volume would be saying that a container can hold 5 gallons, which is the amount of liquid inside the container when it's completely full.
----------
Extra info:
Choice A is false because a substance that does not have a definite shape would be a liquid. Liquids can flow and form to fit any volume. This also applies to a gas as well.Choice B is false because this refers to a solid. A block of ice has a definite shape which is in a block or cube form. Melting that ice will turn it into a liquid which then doesn't have a set shape.Choice C is false as this likely is talking about temperature. Temperature is the measure of how fast a particle is moving. The faster the particle, the more energy and higher temperature it has. On a cold day, the air particles aren't moving as fast compared to a much warmer day when they speed up more.What are functions of the labeled structures?

Which best describes when the body is working on counteracting an effect?
when hormone levels in the body are all equal
during a negative feedback loop
during a positive feedback loop
when the hypothalamus is signaling the pituitary gland
The answer is a negative feedback loop. Negative feedback is used to counteract an effect and achieve back a homeostatic balance. An example of a negative feedback loop is in thermoregulation. When temperatures are too high, the hypothalamus induces body responses such as vasodilation and sweating that enable the loss of excess heat.

California’s San Andres fault is known for its earthquakes. The Pacific plate and North American plate are sliding against each other at this example of a strike-slip fault boundary.
What is Strike-slip fault boundary?Strike-slip faults are the vertical or nearly vertical fractures that occur where the blocks have mostly moved horizontally over each other. If the block opposite an observer, then the fault moves to the right, the slip style is termed right-lateral in this case and if the block moves to the left, the motion is termed left-lateral motion of the block.
The cause of the strike-slip fault earthquakes is due to the movement of the two plates which are against one another and the release of built up strain from these plates. As the larger plates are pushed or pulled in different directions they build up the strain against adjacent plates until it finally fails. The Pacific plate and North American plate sliding against each other is an example of strike-slip fault.

Answer:
9. D (100%)
10. C (Round and Wrinkled)
11. C (75%)
12. B (25%)
Explanation:
9. 100% will be brown, because brown (B) is dominant. That means that if all squares have Bb or BB once you fil out the punnett square, then the offspring would have to show the dominant trait. In this example, all possibilities for the organism were Bb, so brown.
10. Rr and rr are being crossed in this example. Heterozygous is Rr, Wrinkled is rr and Round is RR or Rr. The answer id Round and Wrinkled because one parent is Rr (round) and the other is rr (wrinkled).
11. Yellow seeds are dominant, so any box that has at least one Y will be dominant. 3 of the 4 boxed have a Y, therefore there is a 75% chance the offspring will be yellow.
12. Long hair is not the dominant trait, it is recessive. This means any box WITHOUT a capital S will be recessive. There will be one box, the lower left box. It will be ss. Since one out of four are ss, that means there is a 25% chance the guinea pig will have long hair.

Research and describe the biotic and abiotic factors that work together to create your animal’s habitat. You must research and describe at least 5 total factors, maybe 2 from biotic and 3 from abiotic. You mix how you choose as long as you have a mix of biotic and abiotic totaling 5! Look at the last 2 bullet points below for help.
Describe the impact of your vertebrate (animal) on humans.
Describe humans’ impact on your vertebrate.
You must use at least 2 different resources to find your information.
Biotic Factors to explore--- predators, food preferences and supply, population density (how many of that population in that habitat), other species with which your vertebrate interacts in its habitat (think about your symbiotic relationships-mutualism, commensalism, parasitism), disease
Abiotic Factors to explore---temperature range, precipitation, water, topography (what are the land features-hilly, mountainous, flat, combination), wind, shelter, nesting site and place to raise young, escape routes from predators
Answer: Relevance
The scope of abiotic and biotic factors spans across the entire biosphere, or global sum
of all ecosystems. Such factors can have relevance for an individual within a species,
its community or an entire population. For instance, disease is a biotic factor affecting
the survival of an individual and its community. Temperature is an abiotic factor with the
same relevance.
Some factors have greater relevance for an entire ecosystem. Abiotic and biotic factors
combine to create a system or, more precisely, an ecosystem, meaning a community of
living and nonliving things considered as a unit. In this case, abiotic factors span as far
as the pH of the soil and water, types of nutrients available and even the length of the
day. Biotic factors such as the presence of autotrophs or self-nourishing organisms
such as plants, and the diversity of consumers also affect an entire ecosystem.
Influencing Factors
Abiotic factors affect the ability of organisms to survive and reproduce. Abiotic limiting
factors restrict the growth of populations. They help determine the types and numbers
of organisms able to exist within an environment.
Biotic factors are living things that directly or indirectly affect organisms within an
environment. This includes the organisms themselves, other organisms, interactions
between living organisms and even their waste. Other biotic factors include parasitism,
disease, and predation (the act of one anim

2. When populations are separated into different environments..... *
O Natural selection evolves differences in their body structures.
They immediately develop large differences in structures.
They experience stability over very long periods of time.
They still communicate to go over their differences and how to adapt.
Answer:
MY NAME IS JEFF
Explanation:
When populations are separated into different environments, natural selection can lead to the evolution of differences in their body structures over time. This process is known as divergent evolution, and it occurs when populations that were once similar become increasingly different as they adapt to their respective environments.
What is the explainer to the question asked ?
Over time, populations may develop large differences in their structures as they evolve to better fit their respective environments. For example, if one population lives in a forest environment with lots of trees and vegetation, it may evolve longer limbs and more flexible joints to help it move through the trees.
In contrast, a population living in a grassland environment may evolve shorter limbs and a more compact body shape to help it move quickly across open ground.
While populations may experience stability over long periods of time, this is not always the case. Changes in the environment, such as shifts in climate or the introduction of new predators or competitors, can lead to further evolution and adaptation.
While populations that are separated into different environments may develop differences in their body structures, they may still communicate and exchange genetic material with each other if they come into contact again.
Therefore, This can lead to the exchange of beneficial traits and the potential for hybridization, which can create new genetic combinations and potentially new species over time.

How are some humans using more than their fair share of water? What is the effect of using water on environmental systems?
Please write a full paragraph and cite evidence.
Answer:
Some humans are using more than their fair share of water and it is having a huge impact on the environment. People tend to let their water run while brushing their teeth or shaving, and those are just two of the major problems. There may also be leakages, which can waste gallons among gallons of water. Wasting water hurts humans, it leaves them with less accessible, usable water. Additionally, wasting too much water can hurt the local environment as it drains too much water away from the natural ecosystem.
