These molecules involve an intermediate electron acceptor for oxidations that occur during glycolysis and Krebs reactions. It is part of cellular respiration.
What is cellular respiration?Cellular respiration refers to a series of chemical reactions by which foods can be aerobically converted into energy (ATP) by using oxygen.
Cellular respiration can be divided into Glicolisys, the Krebs cycle and oxidative phosphorylation.
Cellular respiration involves oxide reduction reactions that involve the transfer of electrons (e-) between two or more substances.

Look at these data. Beak depth, the distance from the top to the bottom of the beak, is controlled by the bird's
genes. The bar chart shows the variation in beak size before a drought. The survival of birds after the drought
with a particular bill depth is shown by the yellow line. Explain how these data support the idea of natural
selection among the finches.
Directional selection increased the frequency of individuals carrying the larger bill depths and decreased the frequency of individuals carring small and medium bill depths.
What is directional selection?Natural selection is an evolutive force that favors beneficial alleles and increase their frequency in the population.
Directional selection is the way in which natural selection acts on a population by increasing the proportion of individuals with an extreme phenotypic trait.
This selection presents more frequently in those cases in which interactions between living organisms and the environment modify in the same direction.
Data on the chart Before the drought ⇒ Bar chart.The chart indicates that before the drought, the average size of the bill depth was 9.5 mm. This is an intermediate phenotype between the shortest (7.5 mm) and the largest (11 mm).
So, most individuals in the population expressed the intermediate phenotype of the bill depth.
After the drought ⇒ Line chart
The line chart indicates that, after the drought,
→ only individuals with the largest bill depth (one of the extreme phenotypes) expressed the highest survival rates.
→ Individuals with the shortest bill depth (the other extreme phenotype) expressed the lowest survival rates.
→ Individuals with the intermediate phenotype expressed an intermediate survival rate.
Directional selection favored one of the extreme phenotype -largest bill depths- over the other extreme phenotype and over the intermediate phenotype.
The frequency of individuals carrying the largest bill depths increased.

Why do you think An enzyme in a cell became dysfunctional because of an alteration. As a result, the DNA strands would not separate to begin the replication process. Which enzyme has been affected?The eukaryotic DNA requires multiple origins of replication?
Answer:
1. helicase enzyme
2. Eukaryotic DNA is much larger and replication at multiple origins helps reduce the time required for whole genomes to replicate.
Explanation:
1. During DNA replication helicase enzyme is the enzyme that unwinds 2 DNA strands. Hydrogen bonds present between two strands of the DNA helical which are broken by the helicase enzyme and separate both the strands. Unwinding is essential here as it initiates the replication process.
2. There are multiple origin sites in the eukaryotic DNA due to the larger amount of material to be replicated. To reduces the replication time of the entire genome requires multiple origins of replication.

A boat heading out to sea starts out at Point AA, at a horizontal distance of 1292 feet from a lighthouse/the shore. From that point, the boat’s crew measures the angle of elevation to the lighthouse’s beacon-light from that point to be 12^{\circ}
∘
. At some later time, the crew measures the angle of elevation from point BB to be 6^{\circ}
∘
. Find the distance from point AA to point BB
The distance from point A to point B is 1320.9 feet
What is trigonometric ratio?
Trigonometric ratio is used to show the relationship between the sides and angles of a right angled triangle.
Let h represent the height of the light house, hence:
tan(12) = h/1292
h = 274.6 feet
Let d represent the distance from point B to the feet of the light house, hence:
tan(6) = 274.6/d
d = 2612.9 feet
The distance from point A to point B = 2612.9 feet - 1292 = 1320.9 feet
The distance from point A to point B is 1320.9 feet

what is the fastest land animal?
Answer:
The fastest land animal is the cheetah coming in at 80 miles per hour being the average top speed.
Explanation:
Answer:
Cheetahs are the world's fastest land animal, capable of reaching speeds of up to 70 mph.
Explanation:
At 60–90cm, the muscular tail is half the head and body length. It acts like a counterbalance, aiding high speed manoeuvring. The exceptionally long vertebral column has amazing flexibility, and as it flexes and straightens this boosts stride length.Compared with other cats, all of the leg bones are stretched. The tibia and fibula are also fused to give more stability at speed, though this interferes with climbing.
PLZ help Bees need flowers that produce a lot of pollen. Which biotechnology could scientists use to make flowers full of pollen?
Answer:Pollinating insects such as honeybees play a critical role in maintaining the natural environment. The decline in honeybee populations is a global issue with significant repercussions with respect to the pollination of plants. The simultaneous expression of multifunctionality from synthesized ionic liquid gels (ILGs) for biotechnology is presented in this study. We also demonstrate that, when mixed with photochromic organic compounds, ILGs display rapid color changes, similar to light-triggered camouflage, on living Musca domestica specimens. By further exploiting the physicochemical properties of ILGs, we were able to achieve effective pollen adsorption by ILG-functionalized Formica japonica specimens from Tulipa gesneriana flowers with high biocompatibility. In addition, a radiowave-controllable bio-inspired flying robot equipped with ILG-coated vertically aligned animal hairs could be used to successfully pollinate Lilium japonicum flowers. Such materially engineered artificial plant pollinators should lead to the development of high-performance robotics that can help counter the decline in honeybee populations.

examine the table, if a mutation occurred in the indicated region, which areas would you expect the Pitx1 gene.” check all that apply
Mutation result in changes in the nucleotides sequence in genes, so a mutation of the Pitx1 gene will change the nucleotide sequence in the gene.
What is a mutation?A mutation refers to a change that occurs in the sequence of nucleotides in DNA molecules.
Since gene are regions of a DNA molecule that codes for a protein or gene product, a mutation will affect the gene product.
Therefore, for the Pitx1 gene, a mutation will change the nucleotide sequence in the gene.

Since it is recessive, it will be out ruled unless two recessive genes combine. If one is AA and the other is Aa There will be AA, AA, Aa, Aa. AA is dominant, therefore Aa can have the possibility of either trait. so there is 6 possibility.
What is a Recessive Trait?A recessive trait is a trait that is expressed when an organism has two recessive alleles or forms of a gene. Traits are features of organisms that can be observed, this includes physical characteristics such as hair and eye colour, and also characteristics that may not be readily apparent, e.g. the shape of blood cells.
