Answer:
The overall purpose of the light-dependent reactions is to convert light energy into chemical energy. This chemical energy will be used by the Calvin cycle to fuel the assembly of sugar molecules. The light-dependent reactions begin in a grouping of pigment molecules and proteins called a photosystem.
The light-dependent reactions convert light energy into chemical energy. The goal of the light-dependent reactions of photosynthesis is to collect energy from the sun and break down water molecules to produce ATP and NADPH. These two energy-storing molecules are then used in the light-independent reactions.

You have been assigned a DNA stretch. What is the complementary strand when you replicate the template
Answer:
The complementary strands of a DNA are read in the opposite direction to one another
Explanation:
A DNA strand/stretch can be represented with a number of bases. The bases in a DNA strand are Adenine (A), Thymine (T), Cytosine (C) and Guanine (G). The Adenine can bind to Thymine (and vice-versa) while the Guanine can bind to Cytosine (and vice versa). These bonded bases are called "base pairs".
Complementary DNA strands are read in opposite direction to one another. Each end of a DNA strand is either a 5' end or a 3' end. Hence, if one strand runs from the 5' to 3' end, the complementary strand will run from the 3' to 5'. Thus, they are represented "on paper" the way they run.
For example,
If the DNA strand assigned is AGTCTAG running 5' to 3', the complementary strand will be CTAGACT (starting from the 3' end) and NOT TCAGATC (which starts from the 5' end)

Describe how scent and taste work in conjunction. Are the tastes of below mention foods that were tested heightened by the sense of smell, or only some of the foods?
a. Salt
b. Sugar
c. Lemon Juice
d. Coffe grounds
Answer:
Scent and Taste work in conjunction because when your brain smells food, it pulls up a picture or memory of that food in your head, and you remember what it tasted like and if you enjoyed it.
Only some of the food. Salt does not really have a smell, so it does not do anything, but all the others do and are heightened
Explanation:
Take cotton candy for example. When you smell cotton candy, you smell SUGAR and lots of it. You know that sugar tastes good and as such you now want to eat the cotton candy.
For this example, we will use lemonade. Lemonade is commonly a drink that most love on a hot summer day at the beach. When you smell the lemonade, it reminds your brain of how good it tasted and pulls up the memory at the back of your mind, making you feel happy and relaxed. It then ends up tasting better
(This is my first answer, it won't be perfect)
Smell and taste go hand in hand because when you smell food, your brain conjures up an image or recollection of that food in your head, allowing you to recall how it tasted and if you liked it.
What is Conjuction?Since salt doesn't truly have a fragrance, it has no effect; nevertheless, all the others do and their intensity is increased.
You can definitely smell a lot of sugar when you smell cotton candy. You want to eat the cotton candy because you are aware that sugar tastes delicious.
On a hot summer day at the beach, most people enjoy drinking lemonade.

Transcriptional regulation of operon gene expression involves the interaction of molecules with one another and of regulatory molecules with segments of DNA. In this context, define and give an example of each of the following:
a. operator
b. repressor
c. inducer
d. corepressor
e. promoter
f. positive regulation
g. allostery
h. negative regulation
i. attenuation
Answer and explanation:
The operator is a DNA fragment localized between the promoter and structural gene sequences that are able to repress operon transcription. A repressor is a molecule that binds to the operator to inhibit transcription, while an inducer is a molecule that activates transcription by binding either to the repressors or to the activators. A corepressor is a molecule that binds to repressors in order to activate them. A promoter is a DNA sequence localized upstream structural genes which binds to a transcription factor in order to activate operon transcription. Positive regulation is the process by which operon transcription acts as a positive loop, thereby increasing its own transcription, while negative regulation is the process by which operon transcription inhibits its own expression. Allostery refers to the process by which a molecule regulates operon transcription by binding to distal (and therefore non-functional) sites of the operon. Attenuation is a process able to reduce operon transcription and also to block subsequent translation.

Which type of water pollution is most likely
1 . Nutrient
2.sediment
3.toxic
4. Bacterial
The water pollution that is most likely to occur is Nutrient pollution
Pollution can be defined as the addition of materials or energy (pollutants) to the environment that damages it, making it undesirable or unfit for life. There are different types of pollution which includes:
--> Air pollution
--> Radiation pollution
--> soil pollution and
--> water pollution.
WATER POLLUTION is defined as the type of pollution that occurs when pollutants are being released into water bodies such as streams, lakes, ocean, beaches making it unsafe to use for both human and aquatic life activities. Depending on the type of pollutants, there are also different types of water pollution, these include:
chemical pollution Groundwater pollutionsediment pollutionmicrobiological pollutionnutrient pollutionsurface water pollution and Oxygen-depletion pollution.NUTRIENT pollution occurs when there is EXCESS of it in the water bodies through organic fertilizer or compost manure from the leaves of the cut down trees and shrubs. When nitrates from the agricultural waste gets into the water body(lake) it can cause a drastic increase in aquatic plant growth, especially algal growth. This excessive growth can lead to a decrease in oxygen level of water they by affecting the aquatic life of the lake.
Therefore the CORRECT OPTION is A Nutrient pollution.
Option B is wrong because sediment pollution is a type that involves loose sand, clay, silt, and other soil particles that are carried from a site by runoff water not from cut down trees.
Option C is wrong because toxic or chemical pollution is caused by chemicals from industrial wastes.
Option D is wrong because it is caused by natural existing bacteria in the water bodies and are capable of causing disease when ingested. Example Vibro cholera bacteria.

Apoptosis differs from necrosis in that necrosis:_______ a. requires the reception of an extracellular signal. b. causes DNA to fragment. c. causes cells to swell and burst, whereas apoptotic cells shrink and condense.d. involves a caspase cascade
Answer:
c. causes cells to swell and burst, whereas apoptotic cells shrink and condense
Explanation:
These two mechanism are responsible for death of cells in multi cellular organisms.Apoptosis is naturally occurring process which is well organised and programmed.It is ensures the automatic death of old and worn out cells, needed for certain cellular developments. This is demonstrated by DNA fragmentation,cell shrinkage,and the break down of the nuclear walls.It can be initiated through two pathways of intrinsic and extrinsic,The latter leads to death from internal factors,while in the former is when external factor causes the death .
However,when cell death is influenced by external factors(toxins) in the cell environments,which lead to unpredictable or unregulated process leading to cell death ,the process is called Necrosis.it is demonstrated with the swelling and busting of the cell.and characterised with inflammation. It is an accidental death which causes injuries to the cells and tissues.

Butterflies can produce hundreds of offspring per cross. In a certain variety of butterflies, a maternally-imprintable gene is responsible for wing phenotype. Two possible alleles for this gene are w for normal wings and wc for crinkled wings. Which of the following pieces of information would be helpful in predicting the wing phenotype of a male offspring from a cross?
a. look at the father's phenotype
b. know the mother's genotype
c. look at the mother's phenotype
d. know the father's genotype
Answer: d. know the father's genotype
Explanation: Butterflies can produce hundreds of offspring per cross. In a certain variety of butterflies, a maternally-imprintable gene is responsible for wing phenotype.
The option that would be helpful in predicting the wing phenotype of a male offspring from such a cross would be to look at the father's phenotype.
Imprinted genes can simply be defined as genes that are expressed in parent-of-origin specific manner and result from a chemical modification of DNAs. Such genes are differentially expressed depending on which of the two parents they are inherited from. Hence:
maternally-imprintable genes are only expressed when they are inherited from the father. paternally-imprintable genes are only expressed when inherited from the mother.Phenotype refers to the physical appearance or expression of a gene. Therefore, if a gene is maternally imprintable, looking at the phenotype of the father would be helpful in predicting the phenotype of the male child in case a cross happens.
Applying the same principle to the butterfly, it will, therefore, be helpful to look at the father's phenotype in order to predict the wing phenotype of a male offspring from a cross.
The correct option is A.
