Answer:

An estuary can be defined as partially enclosed coastal body of the brackish water in which one or more than one  rivers flows into it.

It basically forms a transition zone between the river and maritime environments which is known as ecotone.

The salinity of the estuary depends on the location of the estuary. Salinity level in the estuary declines during the spring season and when the snow melts and the rain increases.

The level of the salinity increases during the time of summer because the level of evaporation increases.

Answer:

Salinity in an estuary varies according to one's location in the estuary, the daily tides, and the volume of fresh water flowing into the estuary. In estuaries, salinity levels are generally highest near the mouth of a river where the ocean water enters, and lowest upstream where freshwater flows in.

seraphim [82]

Answer:

Half.

Explanation:

Autosominal dominant trait are express are able to express themselves in the homozygous dominant as well as in the heterozygous condition. The X-linked recessive traits are mostly expressed in males since they have only one X chromosome. Female shows X linked recessive trait when her both X chromosome are affected.

The achandroplastic dwarf man with normal vision is married with a color blind woman with normal height. The mother is affected with vision, she definitely pass this trait to his son. The male is affected with achondroplastic (may be homozygous dominant or heterozygous) and the female is normal (homozygous recessive). The probability can be calculated including both the achandroplastic and vision trait. Half of the males are color blind with normal height (multiplying the probability of vision and achandroplatic trait).

Arrange the steps in order to explain how a tornado form
iogann1982 [59]

<span>Step1; Like all strong winds and storms, tornadoes begin when the sun heats the surface of the land. As the warm, less heavy air begins to rise, it meets the colder, heavier air above it creating a strong circular wind. A wind shear is when two winds at different levels and speeds above the ground blow together in a location. </span>

<span><span>Step 2: </span>The faster moving air begins to spin and roll over the slower wind. As it rolls on, it gathers pace and grow in size.</span>

<span>
Step 3: At this stage, it is an invisible, horizontal wind spinning and rolling like a cylinder. As the winds continue to build up, stronger and more powerful warm air forces the spinning winds vertically upward, causing an updraft.

<span>Step 4: </span>With more warm air rising, the spinning air encounters more updraft. The winds spin faster, vertically upwards, and gains more momentum.</span>

<span>Step 5: At this stage, the spinning winds, creates a vortex and the wind has enough energy to fuel itself.

Step 6: The tornado is fully formed now and moving in the direction of the thunderstorm winds. When the pointed part of the tornado touched the ground from the cloud, it is often referred to as </span>'touch down'<span>
