Answers

Answer:

mitochondria are to produce the energy currency of the cell, through respiration, and to regulate cellular metabolism.

Explanation:

the role of mitochondrion is to generate the energy commodity of the cell, by respiration, and control of cell metabolism.Mitochondrial is the ATP synthesis site for the cell. The amount of mitochondria present in a cell is also a strong predictor of the cell 's rate of metabolic activity; cells that are very metabolically active, such as hepatocytes, may have more mitochondria.

The picture shows a contractile vacuole of a unicellular freshwater organism. The contractile vacuole regulates the flow of water into and out of the cell in an aquatic environement. What condtions cause the contracile vacuole to fill with water? Your answer: The concentration of water is greater outside the cell than inside the cell. The concentration of water inside the cell is the same as the concentration outside the cell. The temperature of water in the vacuole is higher than the temperature of its environment.

Answers

Answer:

The concentration of water is greater outside the cell than inside the cell.

Explanation:

In living cells, water moves by Osmosis across the cell membrane, which acts as the semi-permeable membrane. Osmosis is the movement of water molecules from a region of high water concentration (low solute concentration) to a region of low water concentration (high solute concentration).

The contractile vacuole of this freshwater organism helps regulate water intake and exit by storing excess water. According to osmotic flow, water will flow into the organism via its cell membrane (semi-permeable membrane) because the concentration of water outside the cell is high than inside the cell, hence, this causes an osmotic gradient causing water to flow into the cell. The water that flows into the cell is stored in the Contractile vacuole.

On a hot summer day, Mark recorded the temperatures in the meadow and in the middle of the forest. Based on the results of your experiment, which place was cooler and why?

Answers

the forest would be cooler because the trees are thick and no sunlight is allowed through. things are much cooler when there’s no sunlight allowed near them- think about the difference on a hot summers day sitting in unshaded grass vs sitting in shady grass under a big tree.

Why do you think there is a ring with a dark gap within the body of the wood?

Answers

Near the end of the growing season, they produce denser, darker wood. The light-colored rings are the wood that grew in spring and early summer, while the dark rings indicate growth in late summer and fall. So, a light ring and dark ring together represent one year of growth.

Name 4 ways that different types of disease can interact to make a person ill.

Answers

Answer:

Modes of transmission or means of transmission is defined as the movement or transmission of pathogen from infected person or any reservoir to other person.

4 ways or modes of transmission of diseases include:

Contact (direct and/or indirect) - Direct contact include physical relation between infected person or susceptible person such as kissing, sexual contact or transfer of oral secretion. Diseases caused by direct contact include small pox, pink eye and hepatitis a and B. Indirect contact include transmission of diseases form infected person to susceptible person through a infected surface such as infected needle.Droplet: water droplet coming out of the mouth, perspiration or other open parts of the body carries pathogens to susceptible person. sneezing and coughing are most common of droplet ways through which diseases spread.Airborne: Some of the diseases are spread through means of air such as chickenpox virus, norovirus, measles morbillivirus, Mycobacterium tuberculosis and influenza virus et-cetra.Vector: Vectors are defined as an organism that carries disease causing pathogens from infected person to other host body. Fleas or other insects are example of vectors.

Hence, 4 ways that different types of disease transmission that can make a person ill are droplet, Contact (direct and/or indirect), vectors and airborne.

Explanation:

the DNA is tightly wrapped around histone proteins in a chromosome why is this packaging necessary?
1. Because the dna molecules will down without it .
2. Because the dna molecules will dissolve in cell water .
3.) because the long dna will fit inside the cell.
4.) because the dna needs to attach itself to support .

Answers

Answer:

3.) because the long dna will not fit inside the cell.

Explanation:

This question is oddly written. At first glance, I can tell it's not 1 or 2 because DNA doesn't "dissolve" in cell "water", nor will it "down" (I'm assuming this means "drown"?).

The main reasons for DNA packaging are so that the DNA can fit into the cell, and so it's protected from damage. The DNA is vital to the cell, so it protects it by coiling it up. Coiling and packaging are also important when it comes to gene expression.
