On average, seawater in the world's oceans has a salinity of approximately 3.5%, or 35 parts per thousand<span>. This means that for every 1 litre (1000 mL) of seawater there are </span>35 grams<span> of salts (mostly, but not entirely, sodium chloride) dissolved in it.</span>

About 35 parts per thousand<span>The concentration of salt in seawater (salinity) is about 35 parts per thousand. Stated in another way, about 3.5 percent of the weight of seawater comes from the dissolved salts; in a cubic mile of seawater, the weight of the salt (in the form of sodium chloride) would be about 120 million tons.

Hope this helps .</span>

Describe the process of transpiration in vascular plants.
den301095 [7]

Answer:

This is the diffusion (loss of water vapor) from the stomata (most cases) of a plant to its external environment.

It involves movement of water vapor down the water potential gradients; that is ; from higher water potential inside the leaf to lower water potential in the surrounding environments.

its cools the plant’s  internal temperature as  water vapour conveys heat out of  plants' cells.

What is the purpose of redox reactions in the cell?
Phoenix [80]

Answer:

To discharge energy gradually in a step-by-step process.  

Explanation:

The process of cellular respiration comprises various reactions in which electrons are transferred or mediated from one molecule to another. The reactions taking part in electron transfers are called redox reactions or oxidation-reduction reactions.  

With the movement of electrons the energy is released that can be captivated and is used to do work. In cellular respiration, the electrons from glucose move slowly via the electron transport chain ultimately towards oxygen that is, transferring towards lower and lower energy states and discharging energy at each stage.

The structure and function of specialised cells in multicellular organisms are different. Explain why this is possible if they a
NISA [10]

Answer:

<h2>Differential gene expression </h2>

Explanation:

1. Cell specialization occurs due to the differential gene expression, it is the process which is responsible for the production of cells with different traits at different positions and at different time. This process changes cells  from simple to more specialized in  both structure as well as in function. This is all due to the differential gene expression where all cells beside containing the same gene, express different genes in different cells.

2. Cell differentiation is very important among almost all multicellular organisms. This process results in the  formation of a complex organism with different types of tissues and cells from a zygote.

During which of the following phases of the cell cycle is the nuclear envelope present? Choose all that apply.
cupoosta [38]

Answer:

-S-phase

-Late telophase

Explanation:

The cell cycle is divided into two main phases: interphase and mitotic phase.

Interphase is phase characterized by the the cell growth and DNA copy (replication). During this phase, the cell prepares for division (mitotic phase).

Mitotic phase is subdivided into four phases: prophase, metaphase, anaphase and telophase. At the end of prophase, nuclear envelope breaks down and condensed chromosome (DNA structures) are released.

During the late telophase, nuclear envelope is reformed.

Describe similarities and differences between jonas's family dwelling and the living area at the annex.
Tatiana [17]
<h2>Jonas is impressed and amazed with the similarities and differences between Jonas's family dwelling and the living area at the annex comparing the decorative, luxurious nature and collection of books.</h2>
