What would be the end result if an
experiment supports a hypothesis and
has been repeated?
A. developing a theory
B. redoing the hypothesis
C. graphing the data a different way
D. setting up another experiment based on the same
hypothesis
Answer:
A
Explanation:
The end result of repeated experiments supporting a hypothesis is for the hypothesis to become a theory.
In science, a hypothesis is a general statement that needs to be validated or invalidated by experiments. Once a hypothesis is found to be valid by several independent but similar experiments, such a hypothesis becomes a theory.
Formulation and testing of hypotheses (via experiments) represent two of the key steps in the scientific method.
The correct option is A.
What's the name for the process about how the thermal energy moves in
the ocean?
Answer:
Ocean Thermal Energy Conversion (OTEC)
Explanation:
Only one plane divides the bodies of humans, dogs, and rabbits into roughly symmetrical "left" and "right" halves.
What type of symmetry do these organisms have?
A.
orbital
B.
bilateral
C.
radial
D.
rotational
Answer: Bilateral
Explanation:
symmetry is a type of symmetry in which only one plane divides an organism into halves that are roughly mirror images of each other. The halves need to be mirror images only on the exterior.
If more than one plane of symmetry exists for an organism's body, then it is radially symmetric.

Explanation:
Choose the correct statements 1.Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant. 2.Cross-pollination is the transfer of pollen from the anther of one flower to the stigma of another flower on a different individual of the same species. 3cross-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant. 4.Self-pollination is the transfer of pollen from the anther of one flower to the stigma of another flower on a different individual of the same species.
Answer: The correct statements are 1 and 2:
1.Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant.
2.Cross-pollination is the transfer of pollen from the anther of one flower to the stigma of another flower on a different individual of the same species.
Explanation:
Pollination is the transfer of pollen grains from an anthers to a receptive stigma. In most species of flowering plants, external agents bring about pollination. Also, flowers have evolved special structures and mechanisms to ensure successful pollination.
There are two types of pollination
--> Self pollination: This takes place when mature pollen grains from the anther of a flower fall on the stigma of the same flower or that of another flower on the same plant. This type of pollination brings the male gametes and egg cells of the same plant together. The resultant offspring show very little genetic variation.
--> Cross pollination: This occurs when mature pollen grains of a flower are transferred to the stigma of a flower of another plant of the same or closely related species. This brings the male gametes and egg cells of two different parent plants together. Therefore, there is greater genetic variation among the offspring.
How did Franklin's X-ray photograph affect the work of watson

What is limiting the rate of photosynthesis at point A?
please help me out
Answer:
The factor which is working at the lowest level will usually be the limiting factor of the process. There are several limiting factors which can reduce the rate of photosynthesis , eg temperature, light intensity and carbon dioxide concentration.How does the development of a bluebird compare to that of a frog?
Answer:
Explanation:
Frogs:
Frog's evolutionary pathway resembles the water cycle. This is quite fitting, because all frogs statistically enjoy bodies of water. Seafrogs absorb salt-water through holes, which emit inside the snout. First, they grow two limbs, or legs, to swim. These turn into fins, which, eventually, allow for hopping and balancing-capacity. Capabilities, include: tongue-roll, sticky toes, bubbly neck, multi-eggs, and more

Why do fish need to eat other organisms?
O A. to get energy
O B. to get oxygen
O c. to remove wastes
O D. to escape predators
The correct answer is A. To get energy.
They eat other organisms because they need food, and food is considered energy because it allows the fish to function more efficiently.

im in 7th grade
Answer:
More than 8.7 million species are living on the planet. Every single species is composed of a cell and it includes both single-celled and multicellular organisms.
The cells provide shape, structure and carries out different types of functions to keep the entire system active. The cell contains different functional structures which are collectively called Organelles, and they are involved in various cellular functions.

uhm i have 5 questions due in an hour so please help. It's 45 points and they're all abt biology btw~
Answer:
the point of science is to disprove hypothesis so having a hypothesis that doesn't allow that to happen is not good science
2. they don't fit in our mouths so are a trait from when we had larger jaws
3. bones of your lower jaw, middle ear and voice box (they aren't actually gills fyi, they just look like them)
4. likely yes as their bones were hollow but likely only able to fly short distances, the thought was that they couldn't do their size and weight but with hollow bones they were able to like a quail would
5. no because they could be sister taxa, you would have a hard time proving exactly that this new fossil is the common ancestor that birds came from to replace the old hypothesis (guess) of which one did.
Explanation:
Answer:
A: It is wrong to form a theory that cannot be disproven because the whole point of a theory is to test the theory and prove it.
B: Wisdom Teeth are considered to be a vestigial trait because it is passed along in genetics of humans and is a almost a 100% chance of occurrence.
C: This bird could fly because fossils and research has shown that this creature had similar bone structure to a common day bird.
D: This does not invalidate evolution because many geographic events can happen that may alter the positioning of these fossils like: Any type of corrosion or weathering, or maybe ancient civilization have dug up these fossils and then they were reburied.

For C you can look up archaeopteryx and find an article for evidence

1. Name the protists fitting each of the following descriptions.
Write down only the correct name next to the relevant question number.
1.1 A protozoan which moves using its pseudopodia.
1.2 A protozoan which moves using its flagellum.
1.3 A filamentous green alga.
1.4 A unicellular green alga.
1.5 Microscopic protists which appear as symmetrical, human-made, and
glass-like ornaments.
1.6 Protists that look like fungi.
(6)
Answer:
1.1 Amoeba
1.2 Paramecium
1.3 Citations
1.4 Single algae cells
A protozoa that moves using its pseudopodia is an amoeba, one using its flagellum is Euglena and a filamentous green alga is Spirogyra. Chlamydomonas is a unicellular green alga. Microscopic protists that are symmetrical, man-made and appear as glass-like ornaments are diatoms while a protist that looks like a fungus is a mold.
What are Protists?A protist is a type of eukaryotic organism which is not an animal, plant, or fungus sharing a common ancestor. These are to the exclusion of other eukaryotes which means protists do not form a natural group or clade.
Protists are a group of diverse eukaryotic mainly unicellular microscopic organisms which share certain morphological and physiological characteristics with animals or plants or both.
Several protists showing different functions like an amoeba pushes out its cell membranes to form pseudopods. Euglena belongs to the class of protozoans known as flagellates. Spirogyra has a slender bright green color with a spiral shaped pigment that holds chlorophyll. Chlamydomonas is found in ponds, ditches and moist soil. Diatoms have a silky jewel-like covering. A mold is a protist which is a fungus.
Thus, a protozoa that moves using its pseudopodia is an amoeba, one using its flagellum is Euglena and a filamentous green alga is Spirogyra. Chlamydomonas is a unicellular green alga. Microscopic protists that are symmetrical, man-made and appear as glass-like ornaments are diatoms while a protist that looks like a fungus is a mold.
