Answer:

A.  The particles crossing the membrane do not have a charge.

D.  The movement across the membrane does not require added energy.

F.  The particles crossing the membrane could be water (H2O) or oxygen (O2).

Explanation:

A.  The particles crossing the membrane do not have a charge. - true, only small, uncharged particles can freely cross the cell membrane unassisted.

B.  The movement across the membrane requires energy from ATP. - false, the molecules are moving across the membrane by passive transport, via simple diffusion

C. The movement across the membrane requires energy from glucose. - false, the molecules are moving across the membrane by passive transport, via simple diffusion

D.  The movement across the membrane does not require added energy. - true, the molecules are moving across the membrane by passive transport, which does not require energy.

E.  The particles crossing the membrane could be proteins or carbohydrates. - false, the particles will be smaller than carbohydrates or proteins that can move by passive transport

F.  The particles crossing the membrane could be water (H2O) or oxygen (O2). - true, the particles are likely to be small, uncharged molecules such as water or oxygen

G. The particles crossing the membrane have a strong positive or negative charge - false, the particles are uncharged if they cross the membrane freely

Why is the phloem in a leaf important to the roots of a plant apex?
Nana76 [90]

Answer:

The correct answer will be- phloem transports photsynthetic products to the roots

Explanation:

Phloem is the vascular tissue which specializes in transporting the solute molecules like sugar in the form of sucrose to in the plants.

The phloem connects the photosynthetic organ (Leaves)  to non-photosynthetic organs (stem and roots) of the plants by transporting the photosynthates or sucrose to various parts.

Since the roots also need the energy to perform metabolic functions so need the photosynthates to synthesize the energy molecule. They receive the photosynthates from the phloem.

Thus, phloem transports photosynthetic products to the roots is the correct answer.

What was the Laurentia and what was it composed of? What happened to it?
Nataly [62]
Laurentia<span> (</span>North American Craton<span>) is a large continental </span>craton<span> that forms the ancient geological core of the </span>North American<span> continent. Many times in its past, Laurentia has been a separate </span>continent<span> as it is now in the form of North America, although originally it also included the cratonic areas of </span>Greenland<span> and also the northwestern part of </span>Scotland, known as theHebridean Terrane<span>. During other times in its past, Laurentia has been part of larger continents and </span>supercontinents<span> and itself consists of many smaller </span>terranes<span> assembled on a network of Early </span>Proterozoic orogenic<span> belts. Small </span>microcontinents<span> and oceanic islands collided with and sutured onto the ever-growing Laurentia, and together formed the stable </span>Precambriancraton seen today.
