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

Accidents can occur in meiosis wherein members of a chromosome pair fail to separate at anaphase. This is called _____.
Answer:
Accidents can occur in meiosis wherein members of a chromosome pair fail to separate at anaphase. This is called nondisjunction.
Explanation:
Answer:
Nondisjunction
Explanation:
Nondisjunction occurs when homologous chromosomes or sister chromatids fail to separate during mitosis or meiosis. This leads to daughter cells with unequal amounts of DNA. In fetuses in particular, this type of accident can have extreme consequences, such as the birth of a child with Down's Syndrome or a premature death.
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.

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.
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.

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.
