hydra aurelia sea anemone sea cucumber odd one out
Answer:
The correct answer is - sea cucumber.
Explanation:
Hydra, aurelia, and sea anemone belong to Phylum - Coelenterata or cnidaria while sea cucumber is a member of echinoderms. Cnidaria is radially symmetrical, free-swimming or fixed, aquatic and solitary or colonial animals. While sea cucumber are animals like starfish or sea urchin.
They found on the seafloor and have pentaradial symmetry however, developes bilateral symmetry later.

1. List five organelles eukaryotes have that prokaryotes do not have.
2. Explain how the following organelles ensure that a cell has the proteins it needs: nucleus, rough ER, vesicles,
and Golgi apparatus.
3. What is the main difference between rough endoplasmic reticulum and smooth endoplasmic reticulum?
4. Describe the three types of vesicles.
Answer: 1 Lysosomes and peroxisomes, Microtubules, Endoplasmic reticulum, Mitochondria
2 The role of the nucleus of a eukaryotic cell is to control the cell. Because it contains most of the cell's DNA, which is encoded with genetic instructions, the nucleus controls which proteins the cell makes.
3 The rough endoplasmic reticulum has ribosomes on its surface. This is what give the RER a "rough" appearance. The smooth endoplasmic reticulum (SER) does not contain ribosomes. The Smooth ER looks more like tubes. The SER helps in the storage of proteins and lipids.
4 Secretory vesicles contain materials that are to be excreted from the cell, such as wastes or hormones.
Transport vesicles move molecules within the cells.
Vacuoles are vesicles that contain mostly water.

Explanation:
explain how pH and temperature can affect enzyme activity
Please help has to be due in 20 mins. Thank you for helping me.
Answer:
Enzyme activity depends on many factors such as Substrate concentration, enzyme cofactor, enzyme inhibitors, pH, and temperature. pH and temperature are two important factors that directly affect the activity of an enzyme as follows:
1. pH
Each enzyme has the specific optimal pH that allows it to perform its function to its fullest. The enzymes are the protein made up of the interaction of the hydrogen bond in the side chain of the protein. if there is any change from optimum pH, the enzyme activity decreases until it stops working.
2. Temperature:
Each enzyme has its own optimal temperature. Any modification or change in temperature results in the activity of an enzyme, and it also leads to the denaturation of an enzyme as it is made up of protein.

Answer:
I dont think so
Explanation:
Space has a lack of air, which is how sound travels. It may make some sound, but not alot
Answer:
If they are in space then it is not realistic because sound does not travel in space. Sound is vibrations bouncing off of molecules, but there are no molecules in space to bounce off of.

Lipid synthesis does not occur in any part of the Endoplasmic Reticulum (ER).
TRUE or FALSE:
Answer:
False
Explanation:
The smooth endoplasmic reticulum lacks ribosomes and functions in lipid synthesis but not metabolism, the production of steroid hormones, and detoxification. The smooth endoplasmic reticulum is especially abundant in mammalian liver and gonad cells.
Maria claimed that she could not see through the safety goggles and wore them on top of her head rather than over her eyes. While pouring an unknown chemical into a beaker, she accidently splashed some of the chemical in her eyes. What should Maria immediately do next?
Answer:
She should immediately rinse or flush her eyes with water.
Explanation:
One of the most important precautionary measure to be taken when working with explosive chemicals in the laboratory is the use of safety goggles. However, in this case, Maria claimed that she could not see through the safety goggles and wore them on top of her head rather than over her eyes.
Maria accidentally splashed some chemicals into her eyes while trying to pour it into a beaker. The primary or initial response to this happening is to immediately FLUSH OR RINSE her eyes with water. This will flush away the chemical from her eyes before it can have its detrimental effect.
Answer:
proceed to the eye wash station, open her eyes, and rinse them for at least 15 minutes

Why don’t we include viruses when we discuss reproduction?
Answer:
Viruses latch onto other cells (host cells) in order to reproduce. They do not reproduce by themselves. Instead, they use another cell to repopulate.

why is intensive system the most EXPENSIVE system
Answer:
The intensive farming looks at increasing the yield in the given limited land space with a high dependency on fertilizers, labor, and machinery. ... But as extensive farming is remotely located, the labor cost, the production cost is higher. Also, the output calls for much more care and takes a while to yield the crops.

How are mid-ocean ridges formed at divergent tectonic plates?
The plates are moving in a zigzag formation, creating shallow earthquakes which forms a mid-ocean ridge.
Mid-ocean ridges are not resulting features of ocean-to-ocean divergent boundary zones.
The plates are moving towards each other, which causes the crust to buckle and push upwards or sideways which forms a mid-ocean ridge.
The stretching lithosphere is pushed up as the plates move apart.
Answer:
The stretching lithosphere is pushed up as the plates move apart.
Explanation:
Mid-ocean ridges are basically underwater mountains that are created with the help of lava convection (which causes the rising of plates) and the diverging (the pulling away) of tectonic plates. This is also how ocean floor spreading happens.
I know that mountains are formed by the converging of tectonic plates, but ocean ridges are NOT created like this.

In guinea pigs, the allele for short hair (S) is dominant over long hair (s). If two heterozygous short-haired guinea pigs mate, what percentage of their offspring will have long hair?
Answer:
75% long hair
Explanation:
If you use a table and put Ss for one parent on top and Ss one the side for the other parent you get the result of SS Ss Ss ss which means 75% long hair.

Consider this claim: changes in the environmental conditions always result in new ecosystems and lost of biodiversity charactera.
Answer:
Yes.
Explanation:
Yes, changes in the environmental conditions of a specific region result in formation of new ecosystems as well as the lost of old biodiversity occur because the organisms of that old ecosystem can't tolerate the change that occurs in the environment so they become extinct or migrated to another suitable place and only those organisms begins to live which can survive in that environmental conditions.
