How does the support structure of echinoderms differ from that of arthropods?

Answers

Answer 1

Answer:

Arthropods have a tough, non-living outer shell called exoskeleton, which protect their soft bodies while echinoderms have living endoskeletons, which develops within the deeper skin or body tissues and act as their protective covering.Explanation:

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.

Answers

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.

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.

Please help me :/ im not smart

Answers

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.

how are traits passed down from one generation to another

Answers

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.

What is happening when the angle of the sun hitting the planet during our winter solstice when is that?
WILL BE MARKED BRAINLIEST!

Answers

Answer:The summer solstice occurs at the moment the earth's tilt toward from the sun is at a maximum. Therefore, on the day of the summer solstice, the sun appears at its highest elevation with a noontime position that changes very little for several days before and after the summer solstice.  The summer solstice occurs when the sun is directly over the Tropic of Cancer, which is located at 23.5° latitude North, and runs through Mexico, the Bahamas, Egypt, Saudi Arabia, India, and southern China.  For every place north of the Tropic of Cancer, the sun is at its highest point in the sky and this is the longest day of the year.

The winter solstice marks the shortest day and longest night of the year. In the Northern Hemisphere, it occurs when the sun is directly over the Tropic of Capricorn, which is located at 23.5° south of the equator and runs through Australia, Chile, southern Brazil, and northern South Africa.

Can organisms grow in environments that do not meet their needs?

(Please be legit about the answer thank you)

Answers

Yes organism can grow in environments that do not meet their needs but it would be very hard for them to stay alive in that environment since it doesn’t have all the requirements the organism needs to survive.

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.
