Explanation:
If all cells in your body contain the same set of DNA, why is it that some cells become muscles calls, some become skin, or nerve cells?
Answer:
This is due to CELL DIFFERENTIATION
Explanation:
All living cells are made up of the genetic material called DNA, which are exactly of the same sequence across all cells. However, the cells that contain the same DNA sequence are different in function.
This is as a result of a process called CELL DIFFERENTIATION, which is the process whereby cells specialize or become specific in function as a result of the expresssion or not of certain genes in the DNA sequence of each cell. In other words, cells might contain same DNA sequence but the genes are not all expressed at the same time, leading to the different function. Therefore, some cells become muscle cells, skin, or nerve cells with different functions.
Why is so little of the energy passed on?
Answer:
Why is there less energy at each trophic level?
Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level. ... A food chain can usually sustain no more than six energy transfers before all the energy is used up.

During transpiration, water moves through a plant and moves out into the atmosphere through the leaves. Transpiration is the result of the interaction of which two parts of a plant?
Transpiration is the evaporation of water at the surfaces of the spongy mesophyll cells in leaves, followed by loss of water vapour through the stomata . Transpiration produces a tension or 'pull' on the water in the xylem vessels by the leaves. Water molecules are cohesive so water is pulled up through the plant.
Transpiration is the outcome of the association between the xylem vessels and stomata present in the leaves.
• The evaporation of water at the surfaces of the spongy mesophyll cells in the leaves succeeded by the loss of water vapor via the stomata is termed transpiration.
• Transpiration generates a pull or tension on the water in the xylem vessels, and these molecules of water are cohesive so pulling up of water takes place through the plant.
• The primary sites of transpiration are the stomates present in the leaves. This stomata comprises two guard cells, which produce a small pore on the leaves' surfaces. These guard cells monitor the closing and opening of the stomates in reaction towards different environmental stimuli, and thus, regulate the loss of water by transpiration.

What are the two main phases of photosynthesis called and why?
Answer:
Photosynthesis takes place through several steps which occur during two stages: the light phase and the dark phase.
Explanation:
In the light-dependent process, which takes place in the grana, the stacked membrane structure within chloroplasts, the direct energy of light helps the plant to make molecules that carry energy for utilization in the dark phase of photosynthesis. The plant uses light energy to generate the co-enzyme Nicotinamide adenine dinucleotide phosphate, or NADPH and ATP, the molecules that carry energy. The chemical bonds in these compounds store the energy and are used during the dark phase
The dark phase, which takes place in the stroma and in the dark when the molecules that carry energy are present, is also known as the Calvin cycle or C3 cycle. The dark phase uses the ATP and NADPH generated in the light phase to make C-C covalent bonds of carbohydrates from carbon dioxide and water, with the chemical ribulose biphosphate or RuBP, a 5-C chemical capturing the carbon dioxide. Six molecules of carbon dioxide enter the cycle, which in turn produces one molecule of glucose or sugar.

what would the ploidy of the zygote be if egg and sperm were produced by mitosis rather than meiosis? how would this affect the ploidy of each successive generation?
Answer: the ploidy of the zygote would be genetically identical to the parent cells. since mitosis doesn't reduce the number of chromosomes by half, each successive generation would have twice as many chromosomes as the last.
Explanation:
The ploidy of any zygote formed from egg/sperm produced by mitosis rather than meiosis would be tetraploidy.
Meiosis reduces the diploid chromosome (2N) in parent cells to haploid (n) in the daughter cells. During fertilization two haploid cells (sperm and egg) fuse to form a 2n zygote.
If mitosis replaces meiosis for the production of eggs/sperms, it means eggs and sperms would have complete diploid chromosomes instead of haploid. Thus, during fertilization 2n sperm fuses with 2n egg to form a 4n zygote. A 4n individual is known as a tetraploid.
If mitosis remains as the division for producing eggs and sperms, it means the ploidy level of each successive generation will be doubling from 4n to 8n to 16n, on and on.

What will occur if a species is divided into two groups and allowed to reproduce in different environments for many generations?
Answer:
The original species will diverge into two new species. It will occur speciation. It will occur some sort of allopatric speciation.
Explanation:
When the original species is divided and placed under different environments, where they can reproduce for many generations, many changes or mutations will occur in each group. These changes will depend on each group´s environment and its ecological pressures and will lead to divergence. Pressures act on individuals and make them adapt to the new environmental conditions. Generation after generation, the genotype of individuals will increase the fitness to survive and reproduce. The fixation of mutations will increase the difference among both groups, up to the diverging point into two new species.
The biological concept of species states that individuals of the same species can reproduce because they have a genetic reservoir in common: many genetic variants.
Genetic variability is the measure of a species organism´s tendency to differentiate. In genetic variability, individuals of the same species are not identical. They are recognizable as members of the same species, but they differ in shape, function, and behavior. There exist variations among individuals of the same species.
Genetic variability originates from mutations, recombinations, and karyotype alterations. It allows or makes possible evolution.
Allopatric speciation consists of the geographic separation of a continuous genetic background giving place to two or more new geographically isolated populations. These separations might be due to migration, extinction of geographically intermediate populations, or geological events. In this speciation, some barriers impede genetic interchange, or genetic flux, as the two new populations that are separated can not get together and mate anymore. These barriers might be geographical or ecological.
The process of allopatric speciation involves different steps:
• The emergence of the barrier.
• Interruption in the genetic interchange
• The occurrence of new mutations and their accumulation in time in each population. Slow and gradual differentiation.
• Genetic divergence by natural selection and reproductive isolation makes it impossible for the two groups to mate even if the barrier disappears.
• Prezigotic isolation mechanisms favored by selection once occurs a secondary contact between the new species in formation.
Answer:
divergence, potentially giving rise to two different species

Which statement describes transform boundaries?
O Rift valleys are formed.
O Mountains are created.
O Faults form in the lithosphere.
Plates move toward each other.
Transform boundaries are described as faults that emerge in the lithosphere. So, the correct option is C.
What are Transform boundaries?Transform boundaries, which are often referred to as conservative plate boundaries, are places where two tectonic plates move past one another while moving in opposite directions along a fault in the Earth's crust.
Transform borders happen when two tectonic plates move past one another horizontally via a lithosphere fault. As a result of this movement, rocks may break and slide along the fault, resulting in earthquakes. Transform borders do not include the creation or destruction of crustal material, unlike divergent boundaries where rift valleys are formed or convergent boundaries where mountains are built when plates move towards one another.
Therefore, the correct option is C.

Explain how carbon is related to each of the examples below. (1 point)
Organic matter
Photosynthesis
Cellular respiration
Organic Matter: Carbon (C) is what makes something organic; if it doesn't contain carbon, then it is not a living thing. For this reason, carbon is often considered the element of life.
Photosynthesis: Carbon is part of the compound Carbon Dioxide (CO2), and CO2 is a reactant in the process known as photosynthesis.
Cellular respiration: Although similar to photosynthesis, cellular respiration contains CO2 as a product, not a reactant, as is the case with photosynthesis.
