7. A hen's egg with the shell dissolved is placed in a 10% salt solution. Relative
to the interior of the egg the salt solution is
A. Hypotonic
B. Isotonic
C. Hypertonic
D. Semi-permeable

Answers

Answer 1
A) hypertonic because it has higher salt levels than inside
Answer 2

The salt solution is  Hypertonic.

Hypertonic fluids contain a higher concentration of solute compared to plasma and interstitial fluid.

What is hypertonic solution?A solution that contains more dissolved particles than is found in normal cells and blood.Cells placed in hypertonic solution will shrink. Water moves from a high water concentration inside the cell to a low water concentration outside of the cell by osmosis.

What is osmosis?Osmosis is the movement of water molecules from a solution with a high concentration of water molecules to a solution with a lower concentration of water molecules, through a cell's partially permeable membrane.Osmosis is a passive transport process during which water moves from areas where solutes are less concentrated to areas where they are more concentrated.

Explanation:

lipids are fats oils or waxes. cellulose is a fiber

Answer:

cellulose    

Explanation:

Examples of lipids include fats, oils, waxes, certain vitamins (such as A, D, E and K), hormones and most of the cell membrane that is not made up of protein. Therefore waxes are not the answer.

Steroids are lipids because they are hydrophobic and insoluble in water, but they do not resemble lipids since they have a structure composed of four fused rings. Cholesterol is the most common steroid and is the precursor to vitamin D, testosterone, estrogen, progesterone, aldosterone, cortisol, and bile salts. Therefore steroid and cholesterol is not the answer.

Hydrogen and Oxygen.
Your answer

Answers

Answer:

Water is called the "universal solvent" because it is capable of dissolving more substances than any other liquid. This is important to every living thing on earth. It means that wherever water goes, either through the air, the ground, or through our bodies, it takes along valuable chemicals, minerals, and nutrients.

Which statement correctly demonstrates the relationship between cellular respiration and photosynthesis?

A: The ATP produced by all cells during cellular respiration can be used by plant cells to produce water molecules during photosynthes

B: The glucose produced by plant cells during photosynthesis can be used by all cells to produce ATP during cellular respiration.

C: The oxygen produced by all cells during cellular respiration can be used by plant cells to produce glucose during photosynthesis.

D: The water molecules produced by plant cells during photosynthesis can be used by all cells to produce oxygen during cellular O respiration.​

Answers

Answer:

your answer is B.  The glucose produced by plant cells during photosynthesis can be used by all cells to produce ATP during cellular respiration.

Explanation:

Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.

Calculate the total resistance (in Ohms) of a light bulb marked 2V and 3A. Do not add units. Leave your answer as a decimal to 2 decimal places.

Answers

The total resistance of a light bulb marked 2V and 3A is 0.67ohms

HOW TO CALCULATE RESISTANCE:

The resistance of a substance can be calculated by using the formula as follows:

R = V/I

Where;

R = resistance (in ohms)V = voltage (in volts)I = current (in amperes)

According to this question, a light bulb is marked 2V and 3A. The resistance (R) can be calculated as follows:

R = 2V ÷ 3A

R = 0.67ohms.

Therefore, the total resistance of a light bulb marked 2V and 3A is 0.67ohms.

Answer:The biological levels of organization of living things arranged from the simplest to most complex are: organelle, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystem, and biosphere.

Explanation:Cells are divided into several compartments, each with a characteristic structure, biochemical composition, and function.

These compartments are called organelles. They are delimited by membranes composed of phospholipid bilayers and a number of proteins specialized for each type of organelle.

All eukaryotic cells have a nucleus surrounded by a nuclear envelope, and a plasma membrane that borders the whole cell.

Most eukaryotic cells also have endoplasmic reticulum, a Golgi apparatus, lysosomes, mitochondria, and peroxisomes.

after water, which are the next most abundant substances in the human body?

Answers

Answer:

Proteins

Explanation:

After water, Proteins are the next most abundant substances in the human body.

In adult men , 60% of body is comprised of water whereas in women , 55% of body is comprised of water.

Protein makes up around 20% in body and is present in every cell.

What are Proteins?

Proteins are large complex molecules and play critical roles in the body. They do most of the work in their cells and required for structure functions and regulation of body tissues.

Proteins are made up of smaller units called amino acids, which are attached to one another in long chains.

There are 20 different types of amino acids that can be combined to make a protein.

The sequence of amino acids determines about each protein’s unique 3-dimensional structure and its specific function.

Amino acids are coded by combinations of three DNA building blocks (nucleotides), determined by the sequence of genes.

Functions of Proteins:

1. As an Antibody-  Bind to specific foreign particles such as bacteria and virus to help protect the body.

2. As an Enzyme- Carry out thousands of chemical reactions taking place inside the cell

3. As a Messenger- Transmit signals to coordinate biological processes between different cells, tissues and organs.

4. As a Structural Component- Providing structure and support to cells.

5. Transport/Storage- Binding and carrying atoms and small molecules within cells and throughout the body.
