As a frog develops from a tadpole into an adult frog, it goes through changes that are signaled by hormones within the body. Which best describes the role hormones play in changing a tadpole to a frog?
Answer: In amphibians, metamorphosis is generally associated with the changes that prepare an aquatic organism for a primarily terrestrial existence In (frogs and toads), the metamorphic changes are more dramatic, and almost every organ is subject to modification Regressive changes include the loss of the tadpole's teeth and internal gills, as well as the destruction of the tail. At the same time, constructive processes such as limb development are also evident. The means of locomotion changes as the paddle tail recedes while the hind limbs and forelimbs develop. The tadpole's cartilaginous skull is replaced by the predominantly bony skull of the frog. The teeth used for tearing pond plants disappear as the mouth and jaw take a new shape, and the tongue muscle develops. Meanwhile, the large intestine characteristic of herbivores shortens to suit the more carnivorous diet of the adult frog. The gills regress, and the gill arches degenerate. The lungs enlarge, and muscles and cartilage develop for pumping air in and out of the lungs. The sensory apparatus changes, too, as the lateral line system of the tadpole degenerates, and the eye and ear undergo further differentiation The middle ear develops, as does the tympanic membrane characteristic of frog and toad outer ears. In the eye, both ingratiating membranes and eyelids emerge.

B) algae growing in the water
C) mud on the bottom of the pond
D) amount of light penetrating the water
(First person who answer’s gets brainly plz answer quickly, and no trolling.)
Answer:
B. algae
Explanation:
biotic factor means something alive is in the factor. all the others are abiotic factors
The biotic factor is a living factor providing a source for ecosystem development, hence option b algae in the water are the correct option.
What is a biotic factor of a freshwater pond?A biotic factor is a live entity that influences its surroundings. Aquatic plants, fish, amphibians, and algae are all examples of freshwater ecosystems.
A biotic factor is a live entity that influences its surroundings. Aquatic plants, fish, amphibians, and algae are all examples of freshwater ecosystems.
Turbulence, temperature, water clarity, habitat size, and water depth all influence the structure and function of ponds and lakes. Temperature interacts to affect lake stratification and water circulation.
Therefore algae that balance the aquatic ecosystem is a major abiotic factor, hence option b in water-growing algae is correct.

A scientist is studying a species of mouse living in a field. She observes that the mouse nests are mostly made from cogongrass, a type of grass that is common in the field. After doing some research, she creates the hypothesis that the mice make their nests out of materials that are easy to find.
What would be the scientist's next step in gaining knowledge about how the mice choose their nesting materials?
A.
coming up with more questions about the mice
B.
creating other possible hypotheses about the nests
C.
performing an experiment to test her hypothesis
D.

Answer:
B
Explanation:
Creating other possible hypotheses about the nests.
What is Nesting material?
Everything birds may use to build a nest is referred to as "nesting material."
All birds require suitable materials for their nests, regardless of whether they build a straightforward depression out of wood and straw or a more complex nest structure with complicated construction.
Depending on the size of the nest, where it is built, and how it will be utilized in terms of the number of eggs, several broods, and yearly reuse, different birds will use different materials to build their nests.
Several birds gravitate toward fluffy material, such as seeds with silky attachments designed to blow them on the wind or seed pods with a soft, hair-like covering.
Therefore, Creating other possible hypotheses about the nests.
