The process by which plants take carbon out of the atmosphere is called cellular respiration. photosynthesis. diffusion. combustion.
Answer:
Photosynthesis
Explanation:
Plants remove carbon dioxide from the atmosphere through the photosynthesis process, returning only oxygen to the environment at the end of the process.
Photosynthesis is the process by which plants draw their food from light energy. In order for the plant to produce the energy necessary for its survival, it absorbs carbon dioxide and uses it to produce glucose, which is a carbohydrate used as a source of energy. All carbon dioxide that is not used in this conversion ends up being degraded by the plant.
Research shows that Mount Everest grows an average of 4 millimeters each year. How many years will it take to grow 720 millimeters
Answer:
180 years.
Explanation:
To calculate this we will need to make a very simple calculation, called the "rule of three", which is a calculation used to find the ratio of three factors.
If we look at the question above, we will see that Mount Everest grows 4 millimeters per year (so in our calculation we will use the ratio 4 = 1), but we don't know how many years ago Mount Everest will grow 720 millimeters (so in our calculation we will use the proportion 720= x).
This way we will have the calculation:
4 = 1
720 = X
From this, we will imagine a diagonal line and multiply the values at the end of each line. This way we will have:
4 x X = 1x 720
As a result we will have:
4X = 720
Now we will move all numbers to one side and all letters to the other side. Since the number 4 is multiplying the letter X, it will move to the other side dividing the 720. So we have:
X = 720/4.
As a result we will have:
x = 180 years.

Some researchers suggest that poor regulation of the brain's _____ may lead to panic attacks, which cause the limbic system to become overstimulated.
Final answer:
Researchers believe that dysregulation of the limbic system could lead to panic attacks due to its role in managing emotions and the fight-or-flight response, involving key structures like the amygdala and hippocampus.
Explanation:
Some researchers suggest that poor regulation of the brain's limbic system may lead to panic attacks, which cause the limbic system to become overstimulated. This complex network within the brain is responsible for regulating emotions and behaviors linked to fear, motivation, and memory formation. The amygdala and the hippocampus are key structures within the limbic system that play significant roles in emotional processing. An overactive amygdala can result in heightened fear responses, while alterations in hippocampal volume have been observed in mood disorders. Additionally, the hypothalamus, also part of the limbic system, has outputs that travel through the medial forebrain bundle to influence the autonomic nervous system and regulate stress hormone release.

5. What type of molecule is represented by the model below? (2 points)
Carbohydrate
Steroid
Fat
Nucleic acid
Answer:
Fat
Explanation:
A fat molecule is an ester made from esterification reaction between glycerol & fatty acid.
Fatty acids have a long aliphatic chain and a terminal carboxylic acid (-COOH) group while a glycerol molecule is a 3 carbon compound with each carbon being attached to a hydroxyl (-OH) group. When carboxylic acid (-COOH) group of fatty acid reacts with hydroxyl (-OH) group of glycerol an ester is produced which is known as triglyceride and some residual water is also released in the reaction. To be more specific, in esterification reaction, - OH of hydroxyl (-OH) group of glycerol and -H of carboxylic acid (-COOH) group of fatty acid react to form ester bond between the two & release water.
Fat is a type of triglyceride. There are two types of triglycerides (1) Fats & (2) Oils.

Wastes are poisonous to a cell and must be removed from the cytoplasm. Predict how cell size could affect the removal process and the survival of a cell.
Cell size impacts waste removal; larger cells have a lower surface area to volume ratio, making waste elimination less efficient. The greater distance substances must travel within larger cells slows the diffusion rate, hindering cellular metabolism and potentially causing disease or death.
Cell size can significantly affect the process of waste removal and the overall survival of a cell. The surface area to volume ratio (SA:V) is crucial for efficient waste elimination and nutrient intake. As a cell grows larger, its volume increases faster than its surface area, leading to a lower SA:V ratio. This decrease in ratio means that there is less surface area available for wastes to be expelled relative to the volume of the cell that produces the waste.
Moreover, the distance traveled by substances inside the cell becomes greater in larger cells, slowing down the diffusion rate. Given that a cell's metabolism and the elimination of waste products are critical for its health, cells have evolved to be small or to have specialized shapes that maximize surface area, thus ensuring efficient exchange with their environment. Excessive accumulation of waste products can be toxic and interfere with cellular metabolism, potentially leading to cell death or diseases like cancer and cardiovascular disease.
Ultimately, to maintain a healthy balance and ensure survival, cells need to be able to manage their waste efficiently, which is facilitated by an optimal size and shape that supports rapid transport of materials across the cell membrane.
Phospholipid tails are hydrophilic and are attracted to water true or false
Answer:
False.
Explanation:
Phospholipid tails are hydrophobic, which means that they are repelled by water.
Thus, each phospholipid contains a hydrophobic portion (tails) - represented by fatty acids - and a hydrophilic portion (head) - corresponding to the phosphate group and its associated molecules. A notable fact is that, when placed in water, the phospholipid molecules can assume the shape of a sphere, known as micelle: the polar, hydrophilic portions are distributed in the periphery, while the hydrophobic tails, the tails, are in the inside the micelles away from the water.
Phospholipids are amphipatic molecules composing cell membranes. Their heads are hydrophilic, while their tails are hydrophobic. The statement phospholipid tails are hydrophilic and are attracted to water is false.
What are phospholipids?
Phospholipids are amphipathic molecules arranged in cell membranes. They have
hydrophilic heads facing the exterior and the interior of the cellshydrophobic tails that arrange against each other in the interlayer space.In the membrane, phospholipids can easily change places with other lipids by lateral diffusion in the same layer.
They can also diffuse transversally to the other layer but not as easily as lateral diffusion.
There are also other lipidic movements as rotational diffusion that imply the rotation of the molecule.
The statement Phospholipid tails are hydrophilic and are attracted to water is false. Tails are hydrophobic and reject water.
