D. Ponds and lakes
Explanation:
Limnetic zone is the water area zone where light does not penetrate the bottom as the depth of the water is more towards the center whereas littoral zone is the zone near shore area which is shallow and where plants grow and sunlight penetrates all way in this area. Littoral zone surrounds the limnetic zone in the lake and ponds because the rest of the water bodies mentioned in the question have free flowing water.
Incus is the bone which is not connected to the pelvis directly.
The pelvis is the lower part of the torso, between the abdomen and thighs (sometimes called the pelvic region), with an implanted skeleton.
Incus (inclusive) or anvil is the bone in the middle ear. The small anvil-shaped bone is one of the three ossicles in the middle ear.
The incus receives vibrations from the laterally connected malleus and transmits them to the medial stapes.
Incus Bone has several basic regions. One of its surfaces, called the head, articulates with the knuckle of the malleus. The anvil also has two extensions known as the long crus and the short crus.
Long crus have lenticular projections at the ends. This is the hooked part of the incus that articulates with the head of the stapes.
The short crus is attached to the posterior wall of the middle ear cavity where the ossicles are located. The centre of the incus is also called the body.

Answer:
D
Explanation:
Hope this helps you complete your question :)
First, prophase this is when the chromosomes are just chillin in the nucleus that is protected by the nuclear envelope(the purple circle in the blue circle).
Then, metaphase this is when the nuclear envelope breaks down and the chromosomes line up on the metaphase plate in a line.
Then, anaphase this is when the two chromatids that make up one chromosome are pulled apart by spindles.
Then, telophase this is when the spit chromatids start to form new nucleus and causing the cleavage furrow, the line in between the cells that holds them together, to form.
Finally Cytokinesis, this is where you finally get your too new cells.
Answer:
Endospores.
Explanation:
Microorganisms usually adapt to changes in their environment. One example of an extreme survival strategy employed by certain low G+C Gram-positive bacteria, generally of the Firmicute family, is the formation of endospores. They have a very peculiar structure that helps with this survival feature: an outer proteinaceous coat surrounding the spore provides much of the chemical and enzymatic resistance. Beneath the coat there is a very thick layer of specialized peptidoglycan called the cortex, which aids in resistance to high temperature. They are resistant to desiccation, lysozyme, ultraviolet and gamma radiation, chemical disinfectants, starvation AND temperature. So, in this experiment, it is probable that the boiled broth contained endospores, which survived this heating and then reactivated its metabolism.
