Answer:
Just like eye or hair color, our blood type is inherited from our parents. Each biological parent donates one of two ABO genes to their child. The A and B genes are dominant and the O gene is recessive. For example, if an O gene is paired with an A gene, the blood type will be A.

Two populations of birds with somewhat different coloration live on two different islands. When birds from the two populations are brought together, they produce young whose appearance is intermediate between the two parents. These offspring can successfully breed with each other or with birds from either parent population, and all offspring of these pairings appear intermediate to various degrees. According to the biological species concept, the two populations on different islands ___.
Answer:
represent a single species
Explanation:
According to the biological species concept, a species can be defined as a group of organisms that can potentially interbreed (i.e., mate) in order to produce viable and fertile offspring. Based on this concept, the cohesion forces that maintain the integrity of the species as a single group are 1-interbreeding between its members and 2-reproductive isolation mechanisms that prevent successful mating between organisms from different species. In this case, both bird populations represent the same species because when individuals of these populations are brought together they can interbreed to produce viable and fertile offspring.

Answer:
The first answer is C. photosynthesis
The second is B.
Photosynthesis produces glucose and oxygen, but because the question is asking what food does the equation produce the answer is B not A. Oxygen is a byproduct of photosynthesis and not used by the plant.
Explanation:
When water evaporates from plants through leaves, it diffuses through tiny openings called stomatal pores. If the water vapor needs to diffuse a distance L through one pore to exit the leaf in a time t, what is the time needed for water vapor from the same leaf to diffuse through another pore of length 1.30 L
Answer:
L means same time.
Explanation:
Same time is needed for water vapor from the same leaf to diffuse through another pore of length 1.30 L because the evaporation takes place at the same time in the pore and water is evaporated to the atmosphere but more water is evaporated due to increase of surface area as compared to the other pore that have small opening so the time is same but the amount of water evaporated is different.
There are a number of similarities, and some differences, between the Q cycle in the mitochondrial electron transport system and the PQ cycle found in the chloroplast electron transport system. Sort the items into the appropriate locations, depending on whether they are unique to the PQ cycle, unique to the Q cycle, or common to both.The cycle converts a two-electron transfer process into two one-electron transfer processes.Two electrons are transferred from the reduced carrier to cytochrome c.Addition of electrons one at a time generates a semiquinone intermediate.Used to translocate protons across a membrane.Two electrons are transferred from the reduced carrier to plastocyanin.
Answer:
1. unique to the PQ cycle:
Two electrons are transferred from the reduced carrier to plastocyanin
2. unique to the Q cycle:
Two electrons are transferred from the reduced carrier to cytochrome c
3. common in both PQ cycle and Q cycle:
- The cycle converts a two-electron transfer process into two one-electron transfer processes
- Addition of electrons one at a time generates a semiquinone intermediate
- Used to translocate protons across a membrane
Explanation:
The Q cycle (Q due to quinol) refers to the cycle by which electrons are transferred from ubiquinol to cytochrome c. This cycle is associated with the sequential mechanism of oxidation-reduction between ubiquinol and ubiquinone, also known as Coenzyme Q10 (CoQ10, used as electron carrier), in order to move protons across the inner mitochondrial membrane. In the first phase of the cycle, ubiquinol attaches onto the cytochrome c oxidoreductase, also called complex III (because this complex is the third complex in the electron transport chain), in order to transfer two electrons to the complex. On the other hand, the PQ cycle (PQ due to plastoquinone) refers to the cycle where plastoquinone transports electrons during light-dependent photosynthetic reactions. In the PQ cycle, the plastoquinone serves as an electron carrier through the membrane of the thylakoid. In the first step of this cycle, plastoquinone obtains two electrons from photosystem II and absorbs two protons from the chloroplast stroma, resulting in plastoquinol, which subsequently transfers electrons to plastocyanin in a process coupled with the generation of a proton gradient between the lumen of thylakoid discs and stroma.

A diagram of meiosis I is shown below.
At which stage of meiosis I does the exchange in genetic material between homologous chromosomes result in recombinant chromosomes?
prophase I
metaphase I
anaphase I
telophase I
Answer:
The correct answer is - prophase I
Explanation:
Crossing over or recombination is the event that takes place during the pachytene stage of Prophase I of Meiosis I. During this event, the exchange in genetic material between non-sister chromatids of homologous chromosomes results in the recombination of the genetic material or recombinant chromosome.
Prophase I is the first stage which is characterized by the condensation of the chromosome and form tetrad and appeared to be X like structure in the cell and followed by the crossing over or genetic exchange of homologous chromosomes.

There is a moth in England called the peppered moth. Before Britain's industrial revolution, these moths were usually salt and pepper colored. Because of their coloring, they blended in well with the tree trunks on which they tended to rest. The coloring helped them hide from the birds that ate them. During the British industrial revolution, industry expelled a lot of soot from the burning of coal into the environment. This soot darkened the tree trunks, and it was noted that black-colored moths were becoming predominant. The idea is that with soot in the environment, black-colored moths fared better than light-colored moths. There is some debate as to whether this is actually the case or not, but for the sake of this question, let's assume it is. In your own words, explain the concepts from the four observations discussed in 12.2 using the moth as an example. In other words, how does the moth illustrate the first observation, the second observation, etc.
Answer:
The correct answer is - natural selection in moths.
Explanation:
This is an event of historical Industrial melanism, an event caused by the process of natural selection. Due to this event, the evolution of dark body colors in moth species that present in such habitats become black by industrial soot.
Peppered moths in the UK were pale grey before the revolution of industries, But after the habitat become polluted with soot from coal‐fired industries, melanic snd become numerous and spread to other regions.
After the century the pollution comes down and the pale phenotype becomes the predominant form.

O Studying botany can help us keep our forests healthy.
O Studying botany provides a chance to go on to graduate school.
O Studying botany tells us more about our place in nature.
Answer: Studying botany helps companies develop more abundant food crops for less investment
Explanation:
The reasons for studying botany that is most directly related to increased profits was that "Studying botany helps companies develop more abundant food crops for less investment".
Since more food crops are gotten for less investment, it ultimately means that there'll be a reduction in the cost which will hence lead to an increase in revenue and therefore there'll be an increase in profit.
How are bees vital to our ecosystem? Describe what could happen if bees were to disappear from ecosystem Earth and what the consequences would be. In general, use WHO, WHAT, WHEN, WHERE, and WHY “are bees” DYING off. Lastly, how could We as humans integrate Bee hives efficiency in our own society?
Answer:
They are pollinators.
Explanation:
Bees are vital to our ecosystem because they are pollinators and due to this pollination, these bees are responsible for the presence of trees, shrubs and other small plants etc. if bees were to disappear from ecosystem Earth then the whole world is adversely affected because trees can't produces fruits and seeds so after sometime animals die due to unavailability of food. Human activities are responsible for the death of these bees because human activities causes pollution which is not good for bees. We have to make a safe place for bees and grow as many flowers as you can in order to increase their population.
