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.
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.
Is knowing about physical and chemical changes of food important for a molecular gastronomy chef?
Answer: Yes,
Explanation:
Molecular gastronomy can be defined as a scientific discipline that involves the study of physical and chemical processes that may occur while cooking food. The chefs who are concerned with molecular gastronomy apply their scientific knowledge while cooking. They observe and experiment the change in food appearance, color and fragrance after cooking and try to improve the three parameters to attract the customers.
Which terms identify the role of Fe2+ in the body?
Answer:
no options but read below
Explanation:
Haemoglobin's primary role is to transport oxygen from the lungs to body tissues to maintain basic life functions. Without healthy red blood cells, your body can't get enough oxygen, and this can result in you feeling increasingly tired or exhausted.

Answer:
This woman is likely to be hypothyroid.
Explanation:
The woman has symptoms that may be linked to hypothyroidism, which occurs when the thyroid produces little hormone
thyroid. This disease is more common in women than in men and can be very debilitating if not properly cared for.
The doctor who will assist the woman shown in the question above, should ask questions about what she is feeling and see if she has low immunity, weight gain (in addition to fluid retention), feeling cold, mental depression, menstrual irregularities and constipation .
Finally, the doctor must order a blood test to see if the levels of thyroid stimulating hormone (TSH) and thyroid hormone (T4) are adequate and thus to confirm or not the disease.

why can AIDS be classified as both an infectious disease and an immune system disorder ?
Answer:
Because AIDS can not only be passed from person to person but it can also affect your immune system in ways other infections diseases can not.
Explanation:
for example: type 1 diabetes is an auto-immune disorder and can not be passed on by bodily fluids. chlamydia is an infectious disease that can be passed on by bodily fluids.
AIDS is an auto immune disorder because it affects the immune system in the same ways that other auto-immune disorders do. this being so it can all so be found in the blood and passed on like an infection where as auto-immune disorders normally dont live in a persons blood.

How would the quantity of stomata compare between plants in tropical environments and plants in hot, arid climates? -Plants in tropical climates would have fewer stomata because they would need to prevent the absorption of too much water from the atmosphere. -Plants in hot, arid climates would have fewer stomata because they would need to prevent undesirable water loss from the plant leaves. -Plants in hot, arid climates would have more stomata because they would need to release heat from the leaves to prevent dehydration. -Plants in tropical climates would have more stomata because they would need to absorb more water from the air than plants in arid climates.
Answer:
-Plants in hot, arid climates would have fewer stomata because they would need to prevent undesirable water loss from the plant leaves.
Explanation:
I took the test and got this right.
The necessity to minimize unwelcome water loss from the plant leaves would cause plants in hot, arid areas to have fewer stomata. So, the correct option is B.
What is Stomata?The little apertures known as stomata are found just on epidermis of leaves. Stomata are visible under a light microscope. Stomata can be found on the stems and other portions of various plants. In exchange of gases and photosynthesis, stomata are crucial.
Because they need to take in more airborne water than plants in arid areas, tropical plants would have more stomata. Since they must prevent unwelcome moisture loss from plant leaves, plants in warm, arid climates would develop fewer stomata. The necessity to minimize unwelcome water loss from the plant leaves would cause plants in hot, arid areas to have fewer stomata.
Therefore, the correct option is B.

Which climatic zone is always hot and humid? arid, tropical wet, temperate continental, Mediterranean
Answer:tropical wet, is the anwers
Explanation:
The tropical wet climate zone is the climate zone that is consistently hot and humid. This climate zone is characterized by year-round high temperatures and high humidity, with average temperatures of 80°F (27°C) or more, and annual precipitation of 59 inches (1,500 mm) or more.
What is tropical wet climate zone?The tropical wet climate zone is a type of climate that can be found in areas close to the equator. It is distinguished by high temperature, year-round high humidity and abundant rainfall. Equatorial climate or tropical rainforest climate are other names for this climate zone.
One of the most ecologically diverse regions on Earth is the tropical wet climate zone, which is also an important supplier of natural resources such as timber, fruits and medicinal plants. Deforestation, climate change, and other human activities also pose threats to the region, and they have the potential to have major impacts on the natural and economic systems that depend on this climate zone.
Therefore, the tropical wet climate zone is the climate zone that is consistently hot and humid.

It was Charles Darwin who called the birds seen on the Galapagos islands as the finches. These birds show a remarkable diversification in their beak based on their chief food.
What are Darwin's Finches?Charles Darwin observed a group of small sparrow like black birds with strong, short beaks which are known today as Darwin's finches. These finches varied on different islands, but they were closely related to one another.
These finches evolved from a common ancestors to have different beaks well suited for different types of food they feed on. Generally long and pointed beaks are suitable for seed and cactus feeders. Even some short beaked finches tear up the base of the cactus and feed on its pulp.
The slender and sharp beaks are common in insect eating finches. The process by which they successfully evolved and radiated to different habitats is called the adaptive radiation.
