Answer:
1. Tissues
2. Heterotrophic
3. Body cavity
4. Eukaryotes
5. Radial symmetry; bilateral symmetry.
Explanation:
1. All animals except sponges have tissues, groups of cells that work together to perform a specific function.
Sponges are sea animals which are found attached to surfaces. They are multicellular and heterotrophic like other animals, but they lack true tissues and organs.
2. All animals eat other organisms in order to gain building materials for the body. This makes them heterotrophic, since they obtain necessary energy and chemical building blocks from the environment.
Heterotrophs are organisms that cannot manufacture their own food, but obtain it from their environment instead.
3. One key adaptation of animals was the evolution of a body cavity, a fluid-filled gap between the outer wall of the body and the outer wall of the digestive system.
A body cavity is a space found inside the body that is filled with fluid and which holds and protects internal organs. There are several cavities found in the human body and they are separated by membranes as well as many other structures.
4. All animals are eukaryotes, organisms with cells that are relatively large, complex, and contain membrane-enclosed organelles such as the nucleus.
5. Cnidarians are the only animal phylum to display radial symmetry, meaning that their bodies can be divided any way through the center point to yield two even halves.All other adult animals display bilateral symmetry, meaning that their bodies can only be sliced lengthwise through the midline to produce two even halves.
25 POINTSSS AND BRAINLY THE SELECTED ANSWER IS WRONG BTW
Answer:
The second option
Explanation:
The important point is that the surface area to the volume ratio gets smaller as the cell gets larger. Thus, if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume. That is why cells are so small.

A classmate tells you that the good thing about renewable resources like trees is that you can use them and use them and they will never run out. What is your classmate misunderstanding about renewable resources?
A renewable resource has been different from the nonrenewable one by the fact that the renewable resource is replenished faster than it is used.
What is a Renewable resource?A renewable resource could be defined as a type of resource that significantly continues to exist in nature despite being consumed or can replenish itself over a period of time even as they are utilized by the organisms.
A classmate tells you that the good thing about renewable resources like trees is that you can use them and use them and they will never run out. Renewable resources may include wind power, solar energy, geothermal energy, biomass, etc. These resources are available in nature in unlimited amounts as compared to non-renewable resources.
Therefore, a renewable resource is different from a nonrenewable one by the fact that a renewable resource is replenished faster than it is used.

Matching: Brain Functions
Answer:
Movement: Parietal
Conscious thought: Cerebral Cortex
Personality: Frontal
Speech/language: Cerebrum
Vision: Occipital
Memory: Temporal
Explanation:
The frontal lobe is important for cognitive functions and control of voluntary movement or activity. The parietal lobe processes information about temperature, taste, touch and movement, while the occipital lobe is primarily responsible for vision. The temporal lobe processes memories, integrating them with sensations of taste, sound, sight and touch.

Create a food chain. Choose the biotic factors from the list and move them onto the hotspots marked with circles. BIOTIC FACTORS Trout Algae Herons Minnows Mosquito larvae Regenerate Reset Check
Explanation:
algae(producer)>mosquito lavae>minnows >trout >herons
Algae, Mosquito larvae, Minnows, Trout, and Herons are arranged in the following pattern in a food chain.
What is a food chain?A food chain is an arrangement of organisms where energy flows from through lower organism to higher organism. Each organism in the chain transfers energy to the other organism present at higher order and the flow of energy goes on. Biotic factors, algae, mosquito larvae, minnows, trout, and herons are arranged in the following sequence in the food chain.
Algae are the primary producers in aquatic ecosystems which are eaten by mosquito larvae, which are then eaten by minnows. Minnows are then eaten by trouts. Herons, being the largest predator feeds on the trout.
Each organism in the food chain obtains energy from the organisms present at lower trophic level. However, the energy flow decreases at each trophic level, therefore, the organism at higher trophic level receives the less amount of energy.
Therefore, the food chain is created in the following order: Algae, Mosquito larvae, Minnows, Trout, and Herons.

Two sound waves are moving through a medium at the same speed. If wave x has a greater frequency than wave y, then wave x
Correct Question:
Two sound waves (wave X and wave Y) are moving through a medium at the same speed. If wave X has a greater frequency than wave Y, then wave X
A. has a lower amplitude.
B. has a shorter wavelength.
C. has a longer wavelength.
D. has a greater amplitude.
Answer:
C. has a longer wavelength.
The basic equation of frequency and speed are
velocity = frequency x wavelength
When both waves' velocities are the same then
v1 = v2
f-1 x wavelenght-1 = f-2 x wavelenght-2
Now increasing frequency of wave X will increase the wavelength of wave Y for the equations to be equal.

Infer why base substitutions in the third position are least likely to cause a change in the amino acid for which it coded.
Answer:
Because of the codon oscillation.
Explanation:
The formation of codons is susceptible to the occurrence of oscillation, which is the term that corresponds to the fact that many codons have synonyms in the third position, that is, in the third letter. For example, the codon CUA, which represents leucine, will also represent leucine if it is presented in CUU, CUC and CUG forms, due to the oscillation in the third position. This allows the tRNA to recognize any of these codons and pair with the anticodon smoothly and without errors.

What does pyruvate with O2 go to?
Answer:
In the presence of oxygen, pyruvate is transformed into an acetyl group attached to a carrier molecule of coenzyme A. The resulting acetyl CoA can enter several pathways, but most often, the acetyl group is delivered to the citric acid cycle for further catabolism.

An interesting episode of the aquarium I had was seeing a dolphin show. The dolphin was super smart, and I have to admit it was smarter than me. I mean I was like 3 when I went there so, I guess that is normal? Anyways, the dolphin was doing cool tricks like twist jumping, and even I tried it but failed. The dolphin went to the worker when the worker called its name. I learned that day that you shouldn't underestimate dolphins because they are smart.
