Answer:

The concentration of sugar on the left side of the beaker would reduce while there will be no sugar on the left hand side.

Explanation:

<u>The concentration of sugar on the left hand side of the beaker would reduce and the water level increased while the water level on the right hand side of the beaker would reduce with zero sugar concentration.</u>

<em>Only water molecules are able to move osmotically through a selectively permeable membrane. Water molecules move from the region of low water potential corresponding to the region with no sugar to the region of high water potential corresponding to the region with sugar.</em>

Hence, the concentration of sugar on the left hand side of the beaker becomes diluted as more water moves into it from the right hand side of the beaker through the selectively permeable membrane. Meanwhile. the right hand side remains without sugar but with lower level of water.

Answer: Option C.

<u>Explanation:</u>

Prokaryotic cells are the cells that do not possess a true nucleus. They do not even possess a membrane bound organelles. Organisms with in the domains bacteria and Archaea have prokaryotic cells. The other forms of life are the eukaryotic.

It is a unicellular organism. The word prokaryotic comes from a Greek word. The prokaryotic cells have a cell membrane or a plasma membrane which acts like a protective shield. Along with this, they also have a rigid cell wall which acts like further support and protection.

Black mice and tan mice are native species that are observed in a particular region. Human habitation in the region caused an in
4vir4ik [10]

Answer:

A

Explanation:

The correct answer would be that <u>the availability of food resources for black mice and brown mice will decrease.</u>

<em>Since the food requirements of the black mice are the same as that of the invasive brown mice, the available food supply that used to be only for the black mice would now be shared by the two strains of mice. Hence, the available food for the two groups of mice will naturally decrease.</em>

There is no sufficient information to conclude that the population of tan mice will decrease, hence, option B is incorrect.

The black mice and tan mice have different food requirements going by the information available in the illustration, hence, both cannot compete for food resources. Option C is, therefore, incorrect. In the same vein, option D is incorrect because the tan mice have different food requirements from the brown mice.

<u>The only correct option is A.</u>

The Coriolis Effect is caused by Earth’s uneven distribution of heat AND ________________.
SCORPION-xisa [38]

The rotation of the earth

The Coriolis Effect is caused by Earth’s uneven distribution of heat AND the rotation of the earth

Explanation:

Due to the spherical nature of the earth, when it spins, around its axis, different latitudes spin at different rates. The nearer to the pole you get the slower the earth’s spins (approx 0.00008 kilometers/hr), while this spin is fastest at the equator ( approx1,600 kilometers/hr). Due to this differential spin, ocean and winds currents (while they move polewards due to convection) are deflected as they move towards the pole from the equator. Towards the North, they are deflected westwards while towards the South they are deflected eastwards.
