Answer:

- New seedlings: histone acetylation

- After cold exposure: histone methylation

Explanation:

Vernalization is an adaptive mechanism whose objective is to ensure that flowering occurs only after winter (i.e., after cold conditions). In certain plants, this process (vernalization) suppresses the expression of genes that encode repressors of flowering. In Arabidopsis, vernalization is associated with histone modifications at FLC chromatin. The FLOWERING LOCUS C (FLC) is a MADS-box gene that acts as a repressor of flowering in Arabidopsis. Epigenetic modifications control the expression of the FLC gene. The FLC gene is expressed at low temperatures due to histone acetylation at FLC chromatin, and thereby the expression of FLC mRNA transcripts ensures that the Arabidopsis plant cannot flower. Subsequently, as the Arabidopsis plant is exposed to cold, FLC is repressed by the accumulation of trimethylation on lysine 27 of histone 3 (H3K27me3), thereby allowing it to flower when temperatures become warmer.

Answer:

Most plants appear green because they absorb all other colors of light and reflect back green into our eyes. Since chlorophyll molecules use the red (opposite of green) end of the visible light spectrum to complete photosynthesis, then red is most heavily absorbed.

Chlorophyll gives plants their green color because it does not absorb the green wavelength of white light which is the light wavelength reflected from the plant, so it appears green.

The green color of many plants and algae is due to chlorophyll. Chlorophyll is defined as concentrated within organisms in structures called chloroplasts.

It is the green pigment in plants, algae and cyanobacteria that is essential for photosynthesis. The central structure is an aromatic porphyrin or chlorinated porphyrin ring system with a chelated magnesium atom.

Chlorophyll is formed in several different forms where chlorophyll a and b are the major types found in higher plants and green algae; Chlorophylls c and d are found mainly with a in various algae while the Chlorophyll e is a rare type found in some golden algae and bacterio-chlorophyll is present in some bacteria.

Thus, Chlorophyll gives plants their green color because it does not absorb the green wavelength of white light which is the light wavelength reflected from the plant, so it appears green.

The difference in height between the two bottles is 30 millimeters.

To calculate the difference in height between the two bottles in millimeters, we need to convert the heights from centimeters to millimeters and then subtract one from the other.

First, we convert the height of the first bottle from centimeters to millimeters. Since there are 10 millimeters in a centimeter, we can multiply the height of 12 centimeters by 10 to get the height in millimeters:

12 centimeters * 10 millimeters/centimeter = 120 millimeters.

Next, we convert the height of the second bottle from centimeters to millimeters using the same conversion factor. We multiply the height of 15 centimeters by 10:

15 centimeters * 10 millimeters/centimeter = 150 millimeters.

Now that we have both heights in millimeters, we can calculate the difference. We subtract the height of the first bottle from the height of the second bottle:

150 millimeters - 120 millimeters = 30 millimeters.

Therefore, the difference in height between the two bottles is 30 millimeters.

The difference between hypotonic and hypertonic solutions is that the solutes in hypotonic solutions are less than the solvent, whereas in hypertonic solutions, the solutes are greater than the solvent.

When a cell is placed in a hypotonic solution, water moves into the cell, causing it to grow in size; however, water does not move into the cell in a hypertonic solution such as when a cell is placed in a hypertonic solution, water will move out of the cell, causing it to shrink, such as a cell placed in a salt solution.

Hence, the difference between hypotonic and hypertonic solutions is that the solutes in hypotonic solutions are less than the solvent, whereas in hypertonic solutions, the solutes are greater than the solvent.

The difference between a slate and a gneiss rock that are both formed from shale is due to the degree and type of metamorphism they undergo. Slate has undergone low-grade metamorphism, while gneiss has undergone high-grade metamorphism.

The parent rock plays a role in determining the type of metamorphic rock that will be formed as the mineral composition and texture of the parent rock will affect the metamorphic process.

In a rock that has undergone contact metamorphism, foliation may or may not be present.

Foliated metamorphic rocks, such as slate, phyllite, schist, and gneiss, are formed when the rock is subjected to directed pressure, which aligns the minerals in a parallel or foliated pattern.

However, contact metamorphism is caused by heat and typically does not involve directed pressure, so foliation may not be present in rocks that have undergone contact metamorphism.

To examine the importance of light to a plant's growth.

Explanation:

To give a background to this question, I will define a key term "Photosynthesis". Photosynthesis is a compound word made up of photo (which means "light") and synthesis (which means "to put together").

It is the process by green plants use sunlight to obtain nutrients from carbon dioxide and water.

The experiment us meant to examine the effect of deprivation of sunlight on a plant's growth.

Therefore, the essence of keeping one set of seedlings in the light is to compare if there is any difference in growth between the seeding kept in the dark cupboard and that kept in the light.

This enables us to conclude whether or not light is important for the growth of a plant.

The color, clarity, luster, streak color, hardness, cleavage, distinctive characteristics, and mineral identification should be recorded in Table 5 on the Data Sheet.

When conducting a mineral analysis, it is important to record various properties to accurately identify the minerals. In Step 1, we record the color and clarity of the mineral sample. It's worth noting that some minerals may exhibit more than one color. The color refers to the outward appearance of the mineral, while the clarity pertains to the presence or absence of impurities or inclusions within the mineral.

we determine the luster of the mineral. Luster refers to the way light reflects off the surface of the mineral. It helps categorize minerals as metallic or nonmetallic. If the mineral has a nonmetallic luster, we further specify whether it appears earthy, dull, pearly, silky, waxy, greasy, or vitreous.

involves determining the streak color of the mineral. This is done by scraping the mineral against a streak plate. The color of the streak left behind can be different from the mineral's outward color. However, it's important to note that this test is effective only for minerals softer than the streak plate, which has a hardness of approximately 6.5.

we test the hardness of the mineral using the Mohs Hardness Scale. We try to scratch the mineral against a glass plate. If the mineral scratches the glass, it indicates a hardness greater than 6.0. If it doesn't scratch the glass, we continue down the scale until we find an item that can scratch the mineral or vice versa. The hardness test helps determine the relative hardness of the mineral compared to known substances.

involves examining the cleavage of the mineral. Cleavage refers to the tendency of a mineral to break along flat, parallel planes. If the mineral lacks cleavage planes, it fractures instead. A hand lens may be required to identify cleavage or fracture characteristics accurately.

we record any other distinctive characteristics encountered during the analysis. This could include performing additional tests or observing specific properties unique to certain minerals.

Finally, in Step 8, we compare our findings from Steps 1-7 with the minerals and properties listed in Table 4 to identify the unknown minerals. The names of each identified mineral are then listed in the last column of Table 5.

Following a normal inspiration, the volume of additional air that enters the lungs during forced maximal inspirations called the inspiratory reserve volume.

What is a normal inspiration?

A normal inspiration is the process of breathing that occurs in the lungs when a person inhales air through their nose or mouth, and the air travels down the windpipe and into the lungs. The amount of air that a person inhales during a normal inspiration is called the tidal volume.

Forced maximal inspiration refers to the process of taking a deep breath in, which causes the lungs to expand and allows more air to enter the lungs. During this process, the inspiratory reserve volume is the amount of air that enters the lungs, in addition to the tidal volume, during a maximal or deep breath.

So, the answer is: Inspiratory reserve volume.
