<span>Letter A is the answer. Almost all plant cells have single large central vacuole. These large central vacuoles of the plant cells are filled with water and can take over 80% of its cell volume. This is surrounded by a single membrane called tonoplast. The role of the central vacuole is maintaining the plant cell's pressure.</span>

1. A student is completing a Punnett square for a trait (X/x) that is autosomal and inherited by the dominant allele. The father
zvonat [6]

Answer:

C

Explanation:

autsomsal means that it is not x-linked/ realted to gametes. Dominate means that it needs only one X to get the trait

Using the punnet square

             X       x

      x     Xx   xx

      x     Xx   xx

there is 2 X which means there is a 50% change that their child will get the trait

Before mitosis begins, what happens during S-phase?
Blababa [14]
A
Before meiosis begins, during S phase of the cell cycle, the DNA of each chromosome is replicated so that it consists of two identical sister chromatids, which remain held together through sister chromatid cohesion. This S-phase can be referred to as "premeiotic S-phase" or "meiotic S-phase".

In 6-8 sentences, explain how stream volume and speed affect the size, shape, and flow of streams and rivers. please help me and
nikdorinn [45]

Explanation:

The speed of water in a stream is affected by the gradient of the geography. The steeper the geography the higher the speed of the water flow and the higher the erosion capacity of the stream. This means the stream will be narrow and deep. There is also less meandering of the stream.

When the gradient is less steep, the stream flow slows down and so does the erosion force it bears especially on the river bed. This therefore result in a higher horizontal erosion than vertical erosion. The steam becomes wide and shallow. The stream is also more likely to meander.

The volume of water in the stream also affects the size, shape, and flow of streams and rivers. A higher volume of water has more erosion power due to the weight of the water column. The stream is, therefore, more likely to be bigger in size than a stream that carries low water volume.
