Answer:
It occurs in the green tissue.
Explanation:
they are concentrated particularly in the parenchyma cells of the leaf mesophyll.
Answer:
Photosynthetic cells contain special pigments that absorb light energy. Different pigments respond to different wavelengths of visible light. Chlorophyll, the primary pigment used in photosynthesis, reflects green light and absorbs red and blue light most strongly.In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll. Chloroplasts are surrounded by a double membrane and contain a third inner membrane, called the thylakoid membrane, that forms long folds within the organelle. In electron micrographs, thylakoid membranes look like stacks of coins, although the compartments they form are connected like a maze of chambers. The green pigment chlorophyll is located within the thylakoid membrane, and the space between the thylakoid and the chloroplast membranes is called the stroma (Figure 3, Figure 4).
Chlorophyll A is the major pigment used in photosynthesis, but there are several types of chlorophyll and numerous other pigments that respond to light, including red, brown, and blue pigments. These other pigments may help channel light energy to chlorophyll A or protect the cell from photo-damage. For example, the photosynthetic protists called dinoflagellates, which are responsible for the "red tides" that often prompt warnings against eating shellfish, contain a variety of light-sensitive pigments, including both chlorophyll and the red pigments responsible for their dramatic coloration.
Photomicrographs of chloroplasts with structures labeled are shown alongside a simplified illustration of a photosynthetic cell with a prominent chloroplast. A portion of the chloroplast illustration is depicted enlarged next to the cell to show the structure of a granum, which consists of stacked thylakoids.
Figure 4: Diagram of a chloroplast inside a cell, showing thylakoid stacks
Shown here is a chloroplast inside a cell, with the outer membrane (OE) and inner membrane (IE) labeled. Other features of the cell include the nucleus (N), mitochondrion (M), and plasma membrane (PM). At right and below are microscopic images of thylakoid stacks called grana. Note the relationship between the granal and stromal membranes.

What Are the Steps of Photosynthesis?
Photosynthesis consists of both light-dependent reactions and light-independent reactions. In plants, the so-called "light" reactions occur within the chloroplast thylakoids, where the aforementioned chlorophyll pigments reside. When light energy reaches the pigment molecules, it energizes the electrons within them, and these electrons are shunted to an electron transport chain in the thylakoid membrane. Every step in the electron transport chain then brings each electron to a lower energy state and harnesses its energy by producing ATP and NADPH. Meanwhile, each chlorophyll molecule replaces its lost electron with an electron from water; this process essentially splits water molecules to produce oxygen (Figure 5).
An illustration shows the light and dark reactions for photosynthesis drawn on top of a simplified image of a chloroplast, represented as an oviform capsule. Inside the capsule are five stacks of three or four flat, green thylakoid discs. The discs look like stacked quarters. Two thylakoid stacks have been cut away so that their interiors, which are hollow, are visible.
Figure 5: The light and dark reactions in the chloroplast
Photosynthetic cells contain chlorophyll and other light-sensitive pigments that capture solar energy. In the presence of carbon dioxide, such cells are able to convert this solar energy into energy-rich organic molecules, such as glucose. These cells not only drive the global carbon cycle, but they also produce much of the oxygen present in atmosphere of the Earth. Essentially, nonphotosynthetic cells use the products of photosynthesis to do the opposite of photosynthesis: break down glucose and release carbon dioxide.

Explanation:
If a person in the northern hemisphere observes a full moon, what moon phase would a person in the southern hemisphere observe on the same night? Be detailed in your explanation.
(SCIENCE)
Answer:
nooo
Explanation:
because the earth rotates changing the hemispheres
An increasing waxing moon's phase is seen from the Northern Hemisphere as it moves from right to left. Meanwhile, a waxing moon increases its phase from left to right as seen from the Southern Hemisphere.
What is Hemisphere?Hemisphere is defined as the Earth is evenly divided into two half by any circle that is drawn around it. The atmosphere is one of the fundamental elements of Earth's interrelated physical systems. The layers of gases that envelop a planet or other celestial body are its atmosphere. About 78% of the gases in the Earth's atmosphere are nitrogen, 21% are oxygen, and 1% are other gases.
In comparison to the northern hemisphere, the Moon does appear to be "upside down" in the southern hemisphere. It's only an issue of orientation here. Imagine that the equator and the Moon's orbital plane are the same.
Thus, an increasing waxing moon's phase is seen from the Northern Hemisphere as it moves from right to left. Meanwhile, a waxing moon increases its phase from left to right as seen from the Southern Hemisphere.

sweat acts as a cooling agent on the body because of water high heat of vaporization or high specific heat capacity?
Explanation:
Large amounts of heat are needed to evaporate water, because H-bonds need to be broken. Sweating is an example of using water as d coolant. As the sweat evaporates it pulls heat away from the body. Application 'Water's thermal properties, its high specific heat, means that it can cool us.

Why do we calculate calories per gram instead of just calories?
Because an amount of the said substance emits a specific amount of heat.
In food usually calories are measured per 100 grams.
For biomolecules calories are measured per 1g (e.g. 1g glucose=4.1kcal)

Answer: Positive: Coastal areas help prevent erosion; filter pollutants; and provide food, shelter, breeding areas, and nursery grounds for a wide variety of organisms.
Negative: Added to this are impacts such as increased erosion due to coastal development, increased pollution, and increased boat traffic - all of which lead to further habitat loss and put increased pressure on marine species. ... Other coastal developments can also harm sensitive marine habitats and species.

Limited amounts of specific DNA
Phosphorylation cascade with multiple steps
Receptors that only fit specific hormones
Unique transcription factors made of carbohydrates
Answer:
Unique transcription factors made of carbohydrates
Explanation:
Gene expression refers to the way by which the genes which contain hereditary materials in the cells are converted to certain proteins. Gene expression is regulated to avoid the wastage of useful energy. Transcription allows the copying of genetic information from the DNA to the RNA.
Transcription factors can activate or deactivate a gene thus hindering its expression. Unique transcription factors help to regulate gene expression.
Answer: receptors that only fit specific hormones

Why would a certain trait have a
lower fitness than another causing
that trait to die off in a certain
population?
A. The trait has been around too long to be useful.
B. The trait does not benefit or hinders the
organism.
C. The trait does not wish to be passed on.
Answer: B
Explanation: Traits usually die off when they are unneeded by the organism, or if the trait causes harm to the organism's survival. Through natural selection, over time, the organisms with the best combination of traits for its survival will become the dominating species, and those with weaker traits may not survive long enough to pass off their traits to future offspring.

acid precipitation results when___and____ compounds react with water in the atomsphere
Answer:
Sulfur; nitrogen.
Explanation:
Acid precipitation results when sulfur and nitrogen compounds react with water in the atmosphere.
This acid precipitation is also known as acid rain and it is typically caused by the chemical reaction between sulfur oxide and nitrogen oxide which are released into the air as a result of burning fossil fuels, with water and other chemical elements present in the atmosphere.
Generally, acid precipitation (acid rain) usually have a pH of about 5.1 or below and as such, it is very acidic nature i.e possessing a large amount of hydrogen ions.
Hence, acid precipitation (acid rain) when washed to the earth has negative or harmful effects on various living and non-living organisms such as animals, plants, cars, buildings etc.
