How does the process of photosynthesis support the transformation of energy?.
Answer:
there are two stages of photosynthesis which is the light and dark reaction stage. In the light reaction stage light from the sun is absorbed by the chlorophyll pigments and also split water molecules through a process called photolysis, in this stage light energy is transferred to chemical energy of ATP (adenosine triphosphate) and make reduced NADP (nicotinamide adenosine dinucleotide triphosphate). This stage justifies the second law of thermodynamics which states that the process of energy transformation cannot occur spontaneously unless there is a breakdown of energy from a concentrated form into a dispersed form.

Which living animal is most closely related to Cetaceans such as whales?
answer explanation:
Hippos and whales may look different in many ways, but they are actually each others' closest living relatives—sharing a common ancestor that lived about 55 million years ago.
Hippopotamus furthermore, the DNA testing revealed that whales share a DNA sequence found only in one other animal – indicating that among all the non-whale mammals alive today, whales' closest living relatives are none other than hippopotamus!

Alzheimer's disease: piecing together the evidence assignment
Answer:
Alzheimer's disease is a neurodegenerative disease that usually starts slowly and progressively worsens. It is the cause of 60–70% of cases of dementia. Gradually, bodily functions are lost, ultimately leading to death. The cause of Alzheimer's disease is poorly understood. Other risk factors include a history of head injury, clinical depression, and high blood pressure. Initial symptoms are often mistaken for normal aging. Exercise programs may be beneficial with respect to activities of daily living and can potentially improve outcomes. Behavioral problems or psychosis due to dementia are often treated with antipsychotics, but this is not usually recommended, as there is little benefit and an increased risk of early death.
Explanation:
The course of Alzheimer's is generally described in three stages, with a progressive pattern of cognitive and functional impairment. Detailed neuropsychological testing can reveal mild cognitive difficulties up to eight years before a person fulfills the clinical criteria for diagnosis of Alzheimer's disease. These early symptoms can affect the most complex activities of daily living. The most noticeable deficit is short term memory loss, which shows up as difficulty in remembering recently learned facts and inability to acquire new information. Subtle problems with the executive functions of attentiveness, planning, flexibility, and abstract thinking, or impairments in semantic memory can also be symptomatic of the early stages of Alzheimer's disease.

Thus, There are many reasons why diversity is vital in society and in different situations including the workplace, classrooms, and communities. Here are some main arguments in favour of diversity.
Enhances originality and creativity: A diverse group of people can bring a variety of viewpoints, ideas, and experiences together, which can result in more original and creative solutions to issues or obstacles.
Better decision-making: Diverse teams are more likely to take into account different points of view and strategies, which can result in better choices and better results. It Encourages learning and personal development: Interacting with folks from various backgrounds can assist people in growing.

Which description justifies why the theory of evolution is a theory and not a law?
Answer:
Explains how organisms change in response to the environment
Explanation:
What are some examples of ways homeostasis is maintained in the pH of your blood?
The body must maintain normal blood pressure levels. To accomplish this, the brain sends signals to the heart to speed up or slow down in response to blood pressure. The lungs regulate the pH level in the body. When the pH levels in the body become out of balance, the lungs push more or less carbon dioxide out of the diaphragm.
When a neuron is at rest, the charge difference between the inside and the outside of the axon is -70 millivolts (mV). This value is the ________ of the neuronal membrane.
The resting membrane potential is the difference in voltage through the neuronal membrane when the cell is at rest. -70 millivolts (mV) value is the _resting potential_ of the neuronal membrane.
What is the resting membrane potential?The resting membrane potential is the difference in voltage through the membrane between the neuron interior and exterior when the cell is at rest. This is when the neuron is not sending electric signals.
When the neuron is at rest, most ion channels are closed except for K+ channels, which let the ions get out of the cell according to its concentration gradient. Na+ channels remain closed.
Hence, when the neuron is at rest, the membrane is much more permeable to potassium ions (K+) than to other ions, such as sodium (Na+) and chlorine (Cl-).
This value is the _resting potential_ of the neuronal membrane.

Another trait in pea plants that follows a simple inheritance pattern is flower colour. Purple flowers are a dominant trait while white flowers are a recessive trait.
Explain what this difference means in terms of the alleles for flower colour.
Purple flowers are a dominant trait, so a pea plant only needs one allele for purple flowers in order to have the trait. White flowers are a recessive trait, so a pea plant needs two alleles for white flowers in order to have the trait. If a plant has both a dominant allele and a recessive allele then the dominant trait of purple flowers will be expressed.
When a trait has two separate gene-level versions, there are dominant and recessive traits. The trait that emerges initially or is most obviously displayed in the organism is its dominant trait. Recessive traits are those that are present in the organism but are not visible at the gene level.
The allele that results in a purple flower must be dominant (PP) if a purple and a white flower are crossed and the majority of the offspring are purple. As a result, only the offspring who contain both alleles for white will truly be white (pp). An example of this would be a purple flower, which may have an allele for white but would be purple due to presence of a purple allele (Pp). this type of individual will be heterozygous dominant.The characteristics of an offspring can be easily determined using dominant and recessive alleles.learn more about dominant and recessive traits: https://brainly.com/question/3128896

A conservation biologist has determined the status of the ecosystems in a protected area, as shown in the table below. Based on the table, which part of the pie chart represents secondary succession? Status of ecosystems Percentage of protected area Primary succession 10 Secondary succession 30 Barren land 5 Established community 55 A pie chart titled Status of Ecosystems is divided into 4 unequal parts. From largest to smallest, the parts are: D, C, B, A. Segment A segment B segment C segment D.
Secondary succession is represented in the pie chart tells about the ecosystem succession thus segment c represents most of the succession.
A secondary succession is a form of ecological succession (the evolution of an organic network's ecological structure) wherein flora and animals recolonize a habitat after the main disturbance—which includes a devastating flood, wildfire, landslide, lava flow, or human activity (e.g., farming or street or constructing construction)
What is an example of secondary succession?An instance of secondary succession is the improvement of the recent population to update the preceding network of flora and animals that has been disrupted or disturbed through an event (e.g. woodland fire, flood, harvesting, epidemic disease, pest attack, etc.
Thus it is clear that segment C in the pie chart represents the secondary succession.
