A zoology student is investigating whether it is true that the gender of turtles depends on the temperature at which the turtle

eggs are kept before they hatch. He will test if turtle eggs incubated at 29–30 degrees Celsius produce females, and eggs at 24–26 degrees Celsius produce males. What is the independent variable?

The independent variable is the temperature. Independent variable refers to the  variable in an experiment that can be changed by the scientists or the one making the experiment. A good experiments has a single independent variable and the changes observed will be the dependent variable. In this case, the dependent variable is the gender of the turtle.

Cells can transport these molecules by packaging them into
Paraphin [41]

Answer:

VESICLES

Explanation:

Molecules of different types are produced in different compartments of a cell. These molecules, however, needs to be transported from one location to another. For this purpose, small spherical structures called VESICLES are used by the cell.

Vesicles are compartments in the cell that functions majorly as transport sacs. They help transport materials and molecules from one organnelle to another within a cell. For example, transport vesicles help in the transportation of matured proteins from the Golgi apparatus to respective locations in the cell.

You will be given a stock solution of BSA protein with a BSA concentration of 2 mg/mL. (Here, "mgimL is the concentration unit i
Korolek [52]

Answer: See table in the attachment.

Explanation: 1) The <u>Parallel</u> <u>Dilution</u> <u>Formula</u> is given by:

C_{1}.V_{1} = C_{2}.V_{2}

where:

C is concentration

V is volume

For the given data, index 1 represents the concentration and volume of the stock solution and index 2, the concentration and volume of the diluted solution. For example:

V_{1} = \frac{C_{2}.V_{2}}{C_{1}}

V_{1} = \frac{0.1.100}{2} = 5 μL

V_{1} = \frac{0.15.100}{2} = 7.5 μL

V_{1} = \frac{0.2.100}{2} = 10 μL

V_{1} = \frac{0.25.100}{2} = 12.5 μL

V_{1} = \frac{0.3.100}{2} = 15 μL

V_{1} = \frac{0.35.100}{2} = 17.5 μL

V_{1} = \frac{0.2.100}{2} = 20 μL

Substituing C_{2} for each concentration given and find each volume needed.

The results is shown in the second column of the table.

2) The stock and total volume is determined. So, to calculate the volume of water needed:

V_{H_{2}O} = V_{total} - V_{stock}

V_{H_{2}O} = 100 - 5 = 95 μL

V_{H_{2}O} = 100 - 7.5 = 92.5 μL

V_{H_{2}O} = 100 - 10 = 90 μL

V_{H_{2}O} = 100 - 12.5 = 87.5 μL

V_{H_{2}O} = 100 - 15 = 85 μL

V_{H_{2}O} = 100 - 17.5 82.5 μL

V_{H_{2}O} = 100 - 20 = 80 μL

As shown in the third column of the table.

The sporophyte of what plant group consists of evenly forking photosynthetic stems that lack roots and leaves?
Agata [3.3K]

The sporophyte of <u>whisk ferns</u> consists of evenly forking photosynthetic stems that lack roots and leaves.

Whisk ferns are the elementary and simplest vascular plants.

They contain small-sized protuberances which are called ' enations.'

In these plants, a vascular system is present in the center through which the transport of nutrients and other fluids takes place.

Moreover, roots and leaves are absent in these plants and are composed of forklike stems.

To put it simply, these plants have hair-like structures that are part of the rhizomes. These structures are called rhizoids.
