How does the ear work (the three different segments in the ear)

Answers

The three different segments in the ear are the outer ear, the middle ear, and the inner ear. When you hear a sound, the vibration of the sound travels from the outer ear all the way to the inner ear where the sound is transmitted as information to the brain, and then you realize what kind of sound is heard. For instance, the blowing of a whistle or a school bell.

Which of the following features is found in an insect? indeterminate embryonic cells radial cleavage in embryonic cells coelom formed by a split in the mesoderm

Answers

I believe the answer is indeterminate embryonic cells. Determinate cleavage or the mosaic cleavage (cell division in early embryos) is in most protostomes. It results in the developmental fate of the cells being set early in the embryo development. A cell can only be indeterminate if it has a complete set of undisturbed animal/vegetal cytoarchitectural features. It is a characteristic of deuterostomes- when the original cell in a deuterostome embryo divides, the two resulting cells can be separated and each one can individually develop into a whole organism.

The correct answer is C. Coelom formed by a split in the mesodern

The Eurasian water milfoil is a nonnativespecies, which was once commonly sold as an
aquarium plant, and is now found growing in
many lakes in New York State. It has few
natural enemies, and grows rapidly, crowding
out many native species. This plant ruins fishing
areas and interferes with boating and other
water sports. This is an example of
(1) human consumption of finite resources
(2) an unintended consequence of adding an
organism to an ecosystem
(3) an abiotic factor having a negative effect on
an ecosystem
(4) the introduction of a species that has
increased the long-term biodiversity of an
ecosystem

Answers

The right answer for the question that is being asked and shown above is that: "(4) the introduction of a species that has increased the long-term biodiversity of an ecosystem." This plant ruins fishing areas and interferes with boating and other water sports. This is an example of the introduction of a species that has increased the long-term biodiversity of an ecosystem

Answer:

it would be (2) or B

Explanation:

Because if the plant is commonly sold as aquarium plants then they could have had an unintended consequence of adding an organism to an ecosystem.

Water makes up a large percentage of the body’s cells. For a cell to remain in homeostasis, there must be a mechanism to control water changes in the cells. The movement of water from an area of high water concentration to an area of low water concentration is

Answers

The movement of water from an area of high water concentration to an area of low water concentration is known as osmosis. Diffusion is also one such mechanism in which particles move from high concentration to low concentration. But, there is a difference between diffusion and osmosis. In osmosis, the movement occurs through a semi-permeable membrane. In cells, plasma membrane acts as semi-permeable membrane. Osmosis is a very important phenomenon to sustain life in biological systems because it helps in maintaining homeostasis. Homeostasis on the other hand is a process which aids living beings in regulating their daily activities so as to maintain stable internal environment. For example, if a cell becomes dehydrated (flaccid cell), then it can be easily rehydrated by keeping it in an environment full of water i.e. a hypertonic solution . The water will enter into the cell by osmosis thereby making it rehydrated again.

The movement of water from an area of high concentration to an area of low concentration is osmosis, I believe.
