The energy for the photosynthesis reaction is gained in the first stage of the reaction.
There are 2 stages in photosynthesis:
The light-dependent stageThe light-independent stageDuring the light-dependent stage, an electron in the molecules of chlorophyll gets excited and gets knocked off as a result of photon absorption. A molecule of water is split and the electrons released replace the one lost by the chlorophyll after traveling through the electron transport chain.
The energy from the traveling electron is used to reduce NADP+ to NADPH while the splitting of water to H and O means that a proton gradient is established between the stroma and the thylakoid lumen of the chloroplast. The electrochemical gradient thus created is used by ATP synthase to generate ATP from ADP.
The two chemicals, ATP and NADPH, are then utilized as energy sources for the light-independent reaction.

Which statement correctly
compares humidity in warm and cold air?
A. Warm air holds less moisture than cold air.
B. Warm air will always hold the same amount of moisture as cold air.
C. Warm air can hold more moisture than cold air.
D. Neither warm or cold air can contain water vapor.
Answer:I believe it is c, it makes the most sense to me. I apologize if I’m wrong
Explanation:
The statement which correctly compares humidity in warm and cold air is that warm air can hold more moisture than cold air. Thus, the correct option for this question is C.
What is Humidity?Humidity may be defined as the amount of water vapor present in the atmosphere of living organisms or an ecosystem. If there is a lot of water vapor in the air, the humidity will be high. The higher the humidity, the wetter it feels outside. On weather reports, humidity is usually explained as relative humidity.
High humidity levels are more likely found in warm air. This is because warm air holds more water at higher temperatures. Due to this, warm air has the capacity to hold a lot of moisture.
But on contrary, fewer humidity levels are more likely found in cold air. This is because cold air holds less water at lower temperatures. Due to this, cold air does not have the capacity to hold a lot of moisture.
Therefore, the statement which correctly compares humidity in warm and cold air is that warm air can hold more moisture than cold air. Thus, the correct option for this question is C.

The peppered moth provides a well-known example of natural selection. The light-colored form of the moth was predominant in England before the Industrial Revolution. In the mid-nineteenth century, a dark-colored form appeared. The difference is produced by a dominant allele of one gene. By about 1900, approximately 90% of the moths around industrial areas were dark colored, whereas light-colored moths were still abundant elsewhere. Apparently, birds could really find the light morhs against the soot-darkened background in industrial areas and, therefore, were eating more light moths. Recently, use of cleaner fuels has greatly reduced soot in the landscape, and the dark-colored moths have been disappearing.
1.What forces are causing evolutionary change in these populations?
2. Should the two forma be considered separate species?
3. How would you determine if these are separate species?
4. Give a prediction for what future generations of moths will look like and explain why.
Answer:
a) Natural selection
b) Different
c) Different genotypes
d) Evolution of dark colored moth species from the light colored moth species
Explanation:
a) The pressure of selection due to the changing color of bark of tree because of air pollution caused by industries leads to natural selection in a way that dark colored moth are emerging
b) Yes the two forms of moths are two different species.
c) The genotype of the two species is different
d) All the moths will be of dark color in order to save themselves from predation. This will lead to evolution of dark colored moth species from the light colored moth species and hence will lead to extinction of light colored moth

Give reason why the permeability of both the membrane is same for fatty acid?
Answer:
Because of the amphipathicity and conical molecular shape of fatty acids.
Explanation
They can efficiently incorporate into lipid membranes and disturb membrane integrity, chain packing, and lateral pressure profile. These phenomena affect both model membranes as well as biological membranes. We investigated the feasibility of exploiting fatty acids as permeability enhancers in drug delivery systems for enhancing drug release from liposomal carriers and drug uptake by target cells. Saturated fatty acids, with acyl chain length from C8 to C20, were tested using model drug delivery liposomes of 1,2- dipalmitoyl-sn-glycerol-3-phosphocholine (DPPC) and the breast cancer MCF-7 cell line as a model cell. A calcein release assay demonstrated a reduction in the membrane permeability barrier of the DPPC, proportionally to the length of the fatty acid. Differential scanning calorimetry (DSC) and dynamic light scattering (DLS) experiments revealed that C12 to C20 fatty acids could stabilize DPPC liposomal bilayers and induce large structures, probably due to liposome aggregation and bilayer morphological changes. On the other hand, the short fatty acids C8 and C10 tend to destabilize the bilayers and only moderately cause the formation of large structures. The effect of fatty acids on DPPC liposomes was not completely transferrable to the MCF-7 cell line. Using cytotoxicity assays, the cells were relatively insensitive to the fatty acids at apoptotic sub-millimolar concentrations. Increasing the fatty acid concentration to few millimolar substantially reduced the viability of the cells, most likely via the induction of necrosis and cell lysis. A bioluminescence living-cell-based luciferase assay showed that saturated fatty acids in sub-cytotoxic concentrations could not reduce the permeability barrier of cell membranes. Our results confirm that the membrane perturbing effect of fatty acids on model membranes cannot simply be carried over to biological membranes of live cells.

Explanation:
The Competitive Exclusion Principle states that: Group of answer choices a. When two species occur together, competition is always prevented by some behavioral adjustment. b. Two species that use a limited resource in the same way cannot coexist indefinitely. c. Two species that use the same community can use limited resources in different ways. d. When two species each compete for the same resource in the same location, competition will always evolve into commensalism. e. None of the choices are correct.
Answer:
b. Two species that use a limited resource in the same way cannot coexist indefinitely
Explanation:
The competitive exclusion principle establishes that two or more species that share the same niche requirements, in the same habitat, and are in biological competition for the same resources, won´t be able to coexist indefinitely in the same space if the other ecological factors are constant. This is because species with identical niches have the same necessities, which means that they will compete for the same resources. If these species have the same requirements, they can not coexist. When the superior competitor occupies the inferior competitor´s fundamental niche, the first species has advantages over the second species and monopolizes all the resources. From that moment, the inferior species is displaced and must adapt to use other resources changing its behavior, or must migrate to another area where it can get access to its needs or get extinct.
When two competing species coexist, this is because of niche partitioning or niche differentiation. One of the species uses a different resource, occupies another area, or uses the resources at different times during the day. If there is not any differentiation between them, the dominant species displaces the weak species.
Niche specialization might produce genotypic separation. Subpopulations of a species diverge into new species.
So, competitive exclusion refers to the exclusion of the inferior competitor by the superior competitor when there is not habitat differentiation, and both species can not share the same niche.
Answer:
B. Two species that use a limited resource in the same way cannot coexist indefinitely.
Explanation:
The Competitive Exclusion Principle states that: Two species that use a limited resource in the same way cannot coexist indefinitely.
Explain how the TATA box and transcription factors work together to ensure that RNA polymerase is transcribing the correct region of the DNA molecule.
Answer:
How does RNA polymerase know where to start transcribing a gene?
To begin transcribing a gene, RNA polymerase binds to the DNA of the gene at a region called the promoter. Basically, the promoter tells the polymerase where to "sit down" on the DNA and begin transcribing. ... A promoter contains DNA sequences that let RNA polymerase or its helper proteins attach to the DNA.
TATA box and transcription factors work together to ensure that RNA polymerase is transcribing the correct region of the DNA molecule.
What is transcription?Transcription, the synthesis of RNA from DNA. Genetic information flows from DNA into protein, the substance that gives an organism its form.
The TATA box is able to define the direction of transcription and also indicates the DNA strand to be read. Proteins called transcription factors can bind to the TATA box and recruit an enzyme called RNA polymerase, which synthesizes RNA from DNA.. The TATA box marks a point just before the point at which transcription begins, so that RNA polymerease transcribe the correct region of DNA molecule.

How has the Gila Monster adapted to the breeding patterns of its prey the Gambel quail and desert cottontail rabbits?
The Gila Monster has therefore adapted to consume its entire yearly energy supply in a few meals in the spring. It stores much of its energy as fat in its tail so it can survive the rest of the year.
Answer:
As the Gila monster consumes the eggs or young of the desert cottontail and Gambel's quail, thus its main food supply is only accessible for a restricted time duration every year. However, for this, the Gila monsters exhibit three adaptations, which elevate their survival rate in the desert condition.
