A roller coaster uses the track in this picture. Where - 1

Answers

Answer 1
Answer:

Answer:

Point 2

Explanation:

The answer would be point 2, as it had the highest potential at point 1.

At point 3, it has lost all momentum it had, and has only potential energy.

hope this helps

The body of tapeworm is segmented but it doesnot belong to phylum annelidai why​

Answers

Answer:

look

Explanation:

Flatworms, roundworms, and segmented worms are all invertebrates. Some species of each type of worm are free-living, meaning they are not dependent on another organism.Some are parasitic.

Flatworms belong to phylum Platyhelminthes. They do not have a coelom, respiratory system or a circulatory system.Tapeworms flukes are examples of flatworms.

Roundworms are part of the phylum Nematoda. They are bilaterally symmetrical invertebrates.They have a psuedocoelom. Ascaris lumbricodes is the most common human parasite.

Segmented worms are the most complex animals of these three invertebrates. They are placed in Annelida. Segmented worms have a true coelom, a circulatory system and a digestive system.An earthworm is a segmented worm.

Final answer:

Although tapeworms have segmented bodies, they do not belong to the phylum Annelida due to key biological differences. The segments in tapeworms are reproductive and not involved in locomotion or digestion, unlike in Annelids, and their nervous systems are structurally different.

Explanation:

The body of a tapeworm is indeed segmented, but it does not belong to the phylum Annelida because there are key differences in their biological make-up. Annelids, such as earthworms, have bodies made up of similarly structured segments with a central nervous system. Moreover, these segments have the potential to function independently.

On the contrary, tapeworms, which belong to the phylum Platyhelminthes, while they have segmented bodies, their segments don't have an independent functional capacity. In tapeworms, these 'proglottids' are reproductive in nature and not involved in locomotion or digestion like the segments in Annelids. Additionally, their nervous systems are structurally different from that of the Annelida.

How does a hydrometer work?

A hydrometer is an instrument that measures the specific gravity (relative density) of liquids. The ratio of the density of the liquid to the density of water. A hydrometer is usually made of glass, and consists of a cylindrical stem and a bulb weighted with mercury or lead shot to make it float

What structure do the cells of a maple tree and the cells of a beetle have in common

Answers

Both plant cells and animal cells share characteristics such as nucleus, cytoplasm and a cell membrane. The nucleus controls what goes in and out of the cell, the cytoplasm is where cell activity and chemical reactions occur and the cell membrane holds the cell together.

Spotted owls exist in multiple variations. Two species are shown in the image above. What answer below BEST DESCRIBES the cause & effect of the two different species? Question 1 options:


The common ancestors of these owls were geographically isolated, but can still interbreed, as the allele frequencies have likely not changed much.


The common ancestors of these owls were temporally isolated, but can still interbreed, as the allele frequencies have likely not changed much.


The common ancestors of these owls were geographically isolated, and over time the allele frequencies changed so much they are no longer able to interbreed.


The common ancestors of these owls were temporally isolated, and over time the allele frequencies changed so much they are no longer able to interbreed.

Answers

Answer:

C. The common ancestors of these owls were geographically isolated, and over time the allele frequencies changed so much they are no longer able to interbreed.

Explanation:

This is an example of allopatric speciation. Allopatric speciation, also called geographical speciation, involves the development of a new species when the ancestral population becomes separated by geographical barriers such as a river or a mountain range. This could also take place when the ancestors of the two species emigrate to another area.

In different geographic locations, the separated ancestors undergo gradual evolutionary changes, ultimately, the the two species become so genetically diverse that they cannot interbreed.

C is correct for future users

Which description is true about eukaryotes but not prokaryotes

Answers

Answer:

Eukaryotes are the organism that posses the nucleus in their cell which is the main difference, that gives these cells its name, which is a lack in the prokaryote organisms.

Their many other differences also present that distinct both types of organisms. Eukaryotes contain double membrane-bound organelles such as endoplasmic reticulum, Golgi apparatus, mitochondria, chloroplasts etc. Eukaryotic cells have 80s ribosome which different in the prokaryotes and other differences.

Eukaryotes have a nucleus, prokaryotes do not. While you did not supply descriptions, this is one of the basic and most obvious difference.
