<span>A spider is small enough that its weight can be supported by surface tension, the relatively weak forces that hold water molecules together. </span>Water molecules "bond"<span> to other water molecules around them in all directions, so they tend to stick more strongly to their neighbors, forming a film-like layer across the surface</span>

Which statement describes the semiconservative model of DNA replication correctly? It proposes that the two nucleotide strands u
arsen [322]

Answer: It proposes that the entire double‑stranded DNA molecule serves as a template for a whole new molecule of DNA.

Explanation:

In semi-conservative DNA replication:

- a parent double-stranded DNA splits in two.

- Each strand serves as template, and then read by the enzyme, DNA polymerase, to ensure accurate synthesis of a new daughter strand for both

- the newly synthesized strand contains nucleotides that are complimentary to free nucleotides present in the parent strand.

Thus, because the parent double strand is retained in the newly synthesized DNA, this model is described as semi-conservative

Adjacent plant cells have narrow channels called plasmodesmata that pass through the cell walls of the connected cells and allow
tatuchka [14]

Answer:1. They allow the movement of molecules from one cell to another, enabling communication between cells.

Explanation:the cell wall is a rigid and cellulose containing wall, which surrounds the plasma membrane.

During lignification, small pores appear on the cell wall through which cytoplasmic strands extend.these pores are the plasmodesmata,which provides connections between plant cells

Bingel [31]

Complete question:

You hang a swing from a live tree branch that is roughly parallel to the ground. What will likely happen over time as the tree grows? Check All That Apply

  1. The swing will move farther away from the tree trunk.
  2. The swing will move up. away from the ground.
  3. The swing will remain in its original position.
  4. The swing's ropes will become embedded in the branch.

Answer:

The swing's ropes will become embedded in the branch.

Explanation:

The trunk or branch strangulation sadly occurs very often. When people tie a young tree with different materials, such as a rope, or a cable, or a wire, and leave it there, the leash will eventually strangulate the tree.

Strangulation occurs because the tree keeps growing, applying pressure on the leash. The vascular system is in the trunk perimeter under the crust. Through the years, the pressure increases, the trunk is even more strangulated, and the vascular system is affected. One of the first and principal effects of strangulation is the increase in the trunk or branch diameter over the leash. This diameter change is because elements of the sap can not go back to the roots and keep near the strangulation. At this point, there are two options:

  • The tree can sort this by including the leash in its tissues, surrounding and absorbing it, and keep growing normally

or

  • The vascular system is so affected that the tree can not sort this problem and so, those parts of the tree located over the leash dye.

<em>In the exposed example, it seems that the tree could make it and included the swing's ropes in the branch. </em>

The chemical energy that animal cells use most directly to produce heat and to carry out life processes comes from _______.
notka56 [123]
The chemical energy that animal cells use most directly to produce heat and to carry out life processes come from the oxidation of glucose using oxygen. Cells generate energy from the controlled breakdown of food molecules. During cellular respiration the cells use food molecules, mostly glucose to generate energy in the form of ATP, that used to drive all cellular activities.

A plant's photoperiod is the amount of time each day that the plant receives sunlight. A plant with a 12L:12D photoperiod receiv
satela [25.4K]

Answer:

13L:11D

Explanation:

Based on the photoperiod there are two types of plants -  

a) Short day plant  

b) Long day plant

Here the term short and long day do not mean that the provided length of day are the critical length of day required for reproduction. But opposite to that it means that the length of the day required for reproduction must be  

a) Shorter than the defined length of day for short day plant  

b) And longer than the defined length of day for long day plant  

Chrysanthemums  is a short day plant and thus option 1 with 13L:11D will produce fully developed flower buds

Option A is correct 13L:11D
