If my cultures are suffering severely due to alkaloid production and accumulation in the medium. In that case, how can i overcome this problem?
Explanation:
Alkaloids are essentially natural compounds, and can mostly be used for pharmaceutical purposes. Natural habitats of different alkaloid plants have been destroyed for cultivated.
Many alkaloids are pharmacologically active and are useful as a message for several decades because a wide range of species, such as animals and bacteria, produce them.
Secondary and accumulating metabolites are related to different cell types such as epidermis endodermis pericycle phloem parenchyma, components, accompanying cells etc.

The allele for freckles, F, is dominant among humans. If a woman with freckles (FF) and a man without freckles (ff) have children, what are the possible genotypes of the children?
Answer:
Ff
Explanation:
F - freckles
f - no freckles
FF x ff
F F
f Ff Ff
f Ff Ff
100% with the dominant allele so 100% chance the children will have freckles
---> the possible genotypes are only Ff
Answer:
Ff
Explanation:
100% of the children will have freckles and will have the genotype Ff. If you draw out the punnett square, you will see that an F and an f will be in each box. If this is still confusing, I recommend looking up a video of how to use a punnett square, it will make sense. :)

Explanation:
Anna studies the color of her bedroom wall using different lights. In sunlight, she sees that the wall is white. Anna darkens the room and shines a beam of light that includes all the wavelengths of visible light onto the wall. In this light, what's the wall color that Anna sees?
Answer:
White
Explanation:
The light is measured by its wavelength, generally in nanometers (nm), and visible light has a wavelength spectrum of 400 to 700 nm. Sunlight can be divided into three components: 1-visible light, 2-ultraviolet (UV) light, and 3-infrared radiation. Since white light is visible light (this color contains all the colors of the rainbow) and sunlight includes the visible light of all wavelengths, the object will look white under this light spectrum.
Answer:
white
Explanation:
The concern over green house gases is that by increasing their concentration in the atmosphere, these gases will reduce the amount of Oxygen in the atmosphere

Describe what might happen in the water cycle if
the amount of solar energy entering the Earth
system decreased.
When the amount of solar energy that enters the system become decreased, what may happen in the water cycle are:
evaporation will reduceclouds won't formprecipitation would dropfreezing will occurThe water cycle can be described as a biogeochemical cycle that depicts how water is being circulated and recycled within, above, and on the earth's surface.
A typical diagram showing a water cycle is attached below.
From the water cycle diagram, we can observe that a vital aspect of the water cycle involves the sun which supplies solar energy that heats up earth.
The solar energy entering earth makes it possible for evaporation of water as vapor which form clouds that leads to rainfall.
The solar energy is also important in melting of ice, thereby converting it to water to goes into oceans for evaporation.
The implication of having an earth system where the amount of solar energy that enters it is reduced is that:
evaporation of water will reduced, clouds will not be able to form, and we won't have enough rainfall, andice would be predominant as low solar energy that is required to melt the ice is reduced.In conclusion, when the amount of solar energy that enters the system become decreased, what may happen in the water cycle are:
evaporation will reduceclouds won't formprecipitation would dropfreezing will occurLearn more here:

How is lactase an example of fitness in humans?
[tex] \\ [/tex]
Evolutionary advantages. Lactase persistence is a text-book example of natural selection in humans: it has been reported to present stronger selection pressure than any other known human gene. However, the specific reasons as to why lactase persistence confers a selective advantage "remain open to speculation".
WHAT THEY DO IN HUMAN BODY?Lactase breaks down the lactose in food so your body can absorb it. People who are lactose intolerant have unpleasant symptoms after eating or drinking milk or milk products. These symptoms include bloating, diarrhea, and gas. Lactose intolerance is not the same thing as having a food allergy to milk.
In pastoralist populations, individuals with the lactase-persistence mutations were more likely to survive, reproduce, and pass on their alleles than people without the mutations, especially in times of famine.
