What is the sequence order of DNA?
The four chemical bases of the DNA double helix always associate with the same mate to induce" base dyads," which are appertained to as the sequence order of DNA. Adenine( A) always dyads with thymine( T), but cytosine( C) always dyads with guanine( G).
The natural information that cells bear to develop and serve is decoded in the sequence of the bases, which are constantly appertained to by the original letters of their chemical names A, T, C, andG.
Understanding the function of genes and other factors of the genome depends on establishing the DNA's sequence. DNA sequencing may presently be done using a variety of ways, each with unique parcels, and the creation of new ways is a current focus of genomics exploration.
Sequencing DNA is the process of determining the locales of the four chemical" bases," or molecular structure blocks, that make up the DNA patch. Experimenters can determine what kind of inheritable information is stored in a certain DNA member thanks to the sequence. For case, scientists can use sequence data to determine which DNA stretches include genes and which DNA parts have nonsupervisory instructions that turn genes on and off. Sequence data can also — and this is important — highlight changes connected to genes that might beget complaint.

What are the 4 steps of Calvin cycle?
The Calvin cycle has three basic phases carbon fixation, reduction, and regeneration.
In carbon fixation, two to three molecules of carbon phosphoglycerate are produced when CO2 binds to RuBP. The chloroplast stroma contains the enzyme ribulose bisphosphate carboxylase/oxygenase.
In reduction, 3-PGA molecules are transformed into glucose molecules, which are sugar molecules. Energy for this stage is provided by ATP and NADPH generated during the light-dependent activities of photosynthesis.
In regeneration, third phase requires ATP. At this stage, a portion of the G3P molecules are used to produce glucose, while the remainder are recycled to replenish the RuBP acceptor.
Hence, the calvin cycles provide energy as well as substrate.

how did exercise affect the time needed for the solution to change colour
The pace turns the solution turns yellow during the exercise rises.
When exercising for a predetermined amount of time, the amount of carbon dioxide produced is measured using the acid indicator BTB [Bromothymol blue]. The blue solution turns yellow when carbon dioxide is present. The pace at which the solution becomes yellow increases with the amount of carbon dioxide present. The muscles we use during exercise require more energy. When exercise can be managed, aerobic methods mostly satisfy this need. Since more oxygen is taken in and more carbon dioxide is out when muscles are working hard, this results in an increase in the rate of gas exchange in the lungs. These metabolic gases are carried to and from your tissues by your blood.
The amount of energy your body is using has a significant impact on the amount of carbon dioxide produced. For basic functions including those of your heart and digestive system, your body constantly needs energy. This indicates that carbon dioxide is also continuously released.

Make a claim about how the removal of a population of bats from an
ecosystem could impact at least two other populations in that
ecosystem.
Answer: see below
Explanation:
The removal of a population of bats from an ecosystem could have significant impacts on at least two other populations in that ecosystem. For example, if the bats were a key predator of insects, their removal could lead to an increase in the insect population, which could, in turn, have negative effects on plant populations. Alternatively, if the bats were a major pollinator of certain plants, their removal could lead to a decrease in the plant population, which could have knock-on effects on other species that rely on those plants for food or shelter. Overall, the removal of any species from an ecosystem can have complex and unpredictable impacts on the populations of other species.
Summarize how energy changes during a chemical reaction as bonds are broken and formed. Also Explain the overall function of enzymes in biochemical reactions like photosynthesis and cellular respiration.
Answer:
In a chemical reaction, energy is required to break the existing bonds between atoms in the reactants, and energy is released when new bonds are formed to create the products. The net change in energy during a chemical reaction is known as the reaction's heat of reaction or enthalpy change. This energy change can be either endothermic (absorbing heat) or exothermic (releasing heat), depending on the specifics of the reaction.
Enzymes are proteins that act as catalysts in biochemical reactions. They speed up the rate of a reaction by lowering the activation energy needed for the reaction to occur. In photosynthesis, enzymes facilitate the conversion of light energy into chemical energy that can be used by plants to produce carbohydrates. In cellular respiration, enzymes facilitate the conversion of the chemical energy stored in food into a form that can be used by cells to produce ATP, the primary energy currency of the cell. Overall, enzymes play a crucial role in enabling the chemical reactions that sustain life.

having freckles is dominant over not having freckles, and curly hair is dominant over straight hair. one parent is homozygous for freckles and has straight hair. the other parent does not have freckles and has straight hair. what are the possible phenotypes of the offspring? freckles with curly hairfreckles with straight hairno freckles with curly hairno freckles with straight hair
Answer:
freckles with straight hair
no freckles with straight hair
Explanation:
In this scenario, having freckles is dominant over not having freckles, and curly hair is dominant over straight hair. The first parent is homozygous for freckles, meaning that they have two copies of the gene for freckles, and they have straight hair. The second parent does not have freckles and has straight hair.
There are two possible genotypes for the first generation offspring[F1] with respect to freckles: they could inherit one copy of the gene for freckles from each parent (meaning they would be heterozygous for freckles and would have freckles), or they could inherit two copies of the gene for not having freckles [meaning they would be homozygous for not having freckles and would not have freckles].
There are also two possible genotypes for the offspring with respect to hair type: they could inherit one copy of the gene for straight hair and one copy of the gene for curly hair (meaning they would be heterozygous for straight hair), or they could inherit two copies of the gene for straight hair (meaning they would be homozygous for straight hair and would have straight hair).
Given these possible genotypes, there are four possible phenotypes for the F1 offspring: freckles with straight hair, freckles with curly hair, no freckles with straight hair, and no freckles with curly hair. However, since both parents have straight hair, it is not possible for the offspring to have curly hair, so the only possible phenotypes are freckles with straight hair and no freckles with straight hair.
Answer:
