Answer:
Yes
Explanation:
In natural systems, both energy and matter are conserved within a system. This means that energy and matter can change forms but cannot be created or destroyed.

Give examples of animals in the phylum arthropoda. What is their importance?
Answer:
Arthropods play an important role in maintaining the health of ecosystems, provide livelihoods and nutrition to human communities, and are important indicators of environmental change. Yet the population trends of several arthropods species show them to be in decline.
Explanation:

(Write a brief summary for people who aren’t familiar with the science of bringing back extinct species). This section should be at least one paragraph which includes information on how cloning works (in your own words), the opinion you stated in step one (we should try to bring back extinct animals) and your supporting evidence.
Answer:
Earth is in the midst of its sixth mass extinction: Somewhere between 30 and 159 species disappear every day, thanks largely to humans, and more than 300 types of mammals, birds, reptiles, and amphibians have vanished since 1500. These rates do not bode well for the future of life on our planet, but what if extinction wasn’t permanent? What if we could resurrect some of the species we’ve lost?
For decades the notion of “de-extinction” hovered on the scientific fringes, but new advances in genetic engineering, especially the CRISPR-Cas9 revolution, have researchers believing that it’s time to start thinking seriously about which animals we might be able to bring back, and which ones would do the most good for the ecosystems they left behind.

Please help me :/ im not smart
Answer:
Well I'm not smart either. But i'll give you the answer.
Explanation:
Since the population of gray squirrels and brown squirrels decreased, and the population of black squirrels increased, that means the gray and brown squirrels were eaten/left and didn't blend in very well to their habitat. However, the population of black squirrels increased, so they blended in well with their environment. This tells us that the color of the trees became darker, closer to black, since there were more of them.
Answer: in explanation
Explanation:
Over time the color of the trees changed to black or a dark color. Because the color of the trees changed the gray and brown squirrels were more noticeable to the foxes causing them to be killed off. This meant over time the squirrells with black fur survived and bred eventually populating the area with black squirrells.

What are two benefits of having a soft mostly hollow spongey part of our bones?
~Will give Brainliest if you give me a good paragraph and it's correct~
Answer:
The lamellae of spongy bone will form an open for the porous network of bony branches, or beams, called trabecula.
It also gives the bone strength and make the bone lighter. This also allows room for blood vessels and bone substance. Subscribe to amiredagoat Yt pls

Which has the greatest long-term impact on local water availability?
A. runoff
B. climate
C. pollution
Answer:
answer is most likely B.
Explanation:
Because with climate/ weather change water can change easily for example water can evaporate as it gets hotter and a colder climate can kind of grasp more water.
Which diagram correctly portrays the direction of the prevailing winds in each latitude band? (look at the pictures)
A.
E.
B.
C.
D.
Option C and E are the diagram which correctly portrays the direction of the prevailing winds in each latitude band
what is latitude?Latitude and longitude are two most important terms which are the coordinates that, together, tells exactly location of an object on the surface of the Earth.
Latitude tells the position of the object or anything between the North Pole and the South Pole where equator is zero degrees, the North Pole is 90 degrees North, and the South Pole is 90 degrees .
Parallels called as latitude lines which run across the Earth from east to west at a constant latitude, for example would be the equator, which is at zero degrees of latitude
Latitude is major indicator of navigation because the path of the sun is different depending on the object's latitude, so it varies based on the time of year.

How is information passed between neurons in the body?
A. through impulses
B. through motor neurons
C. through interneurons
D. through sensory neurons
Answer:
The place where the axon of one neuron meets the dendrite of another is called a synapse. Neurotransmitters travel across the synapse between the axon and the dendrite of the next neuron. Neurotransmitters bind to the membrane of the dendrite. The binding allows the nerve impulse to travel through the receiving neuron.
Explanation:
Answer:
D. sensory neurons

The characteristics of vitamins and minerals are they help your immune system fight disease and they help the body get energy.
What are the functions of vitamins and minerals?Vitamins and minerals help us fight infections, heal wounds, build strong bones, and regulate hormones, among other bodily functions. Nutrients and minerals can cause harmfulness whenever consumed in enormous sums.
Vitamins and minerals are essential for healthy growth and development in children. A variety of foods from each of the five food groups can provide vitamins and minerals to children.
In contrast to other dietary components known as macronutrients (such as fats, carbohydrates, and proteins), which are the compounds utilized in the reactions regulated by the vitamins, the vitamins regulate reactions that occur in metabolism.

1. Write a sentence explaining the relationship between the words DNA, genes, and chromosomes.
2. Name three examples of genetic traits that you inherited from your parents.
how are traits passed down from one generation to another
Answer:
Genes & DNA
Explanation:
Heritable traits are known to be passed from one generation to the next via DNA, a molecule that encodes genetic information.Organisms inherit genetic material from their parents in the form of homologous chromosomes, containing a unique combination of DNA sequences that code for genes.
Answer:
Traits are passed down from one generation to another because of DNA.
Explanation:
Genetic inheritance occurs due to genetic material, in the form of DNA, being passed from parents to their offspring. When organisms reproduce, all the information for growth, survival, and reproduction for the next generation is found in the DNA passed down from the parent generation.
Can organisms grow in environments that do not meet their needs?
(Please be legit about the answer thank you)
Answer:
In most cases, no.
Explanation:
Some basic needs of an organism are an appropriate environment ( E.g. Having water for fishes, be it salty or fresh), have a reasonable temperature and pH value of its surroundings, and having enough food to sustain itself. You can even look at things like air composition.
There's no way an organism that normally lives in slightly alkaline water can survive in water with a pH of 3. Similarly, organisms can't survive in unsuitable temperatures, like how a polar bear can't survive in the desert.
In cases like food, they would die from starvation without appropriate amounts of food.
In essence, an organism is not likely to be able to grow in environments that do not meet their needs.
Some organisms adapt and change over time depending on the organisms, but most of them may die before adulthood.
