The opossum is a new arrival in southern Ontario. Its niche is similar to that of the raccoon. An opossum has a long, bare, rat-like tail. A raccoon has a long, bushy tail. How is this a selective advantage for the raccoon?
Answers
The long, bushy tail of the raccoon may be a selective advantage for this species because the bushy tail helps keep the face warm during a snowstorm (Option d). In addition, it may serve as camouflage and also may act to communicate with other members of the population.
What is an evolutionary selective advantage?An evolutionary selective advantage is a feature in a species that confer an advantage to survive and reproduce in a particular environmental condition, which may be associated such as in this case to the tail in raccoons.
Therefore, with this data, we can see that an evolutionary selective advantage is any phenotypic feature that enhances the survival and or reproductive rate of individuals in a population or species.

Consider the global 'Greenhouse Effect", where thermal energy from the sun is naturally trapped by 'greenhouse gases' present within the Earth's atmosphere. A majority of heat generated from this process is then absorbed by the world's oceans, where it is sequestered and stored. What are some of the predictable consequences recently observed over the past 40-50 years with the observed rise in Global Mean Temperature, correlate with an increase in greenhouse gas emissions from burning of fossil fuels across that same period?
a. retreat of winter and summer sea ice, decreasing the amount of solar energy directly absorbed into the oceans
b. warming of deep ocean water and increased evaporation at the surface
c. warming of oceanic surface temperatures, driving the formation of more powerful hurricanes & rainstorms
d. thermal expansion of oceanic water, leading to mean global sea level rise
e. melting of Himalayan glaciers and collapse of Antarctic ice shelves into the sea
Answers
Answer: it would be C e is correct however but that’s already happened. So that wouldn’t be much of a prediction. Hope this helped :)
Explanation:
Thermal expansion of oceanic water leads to a main global sea level rise. So the correct option is D.
What is the greenhouse effect?
Because it absorbs heat in the form of infrared light from the Sun, a greenhouse gas circulates that heat throughout the atmosphere before losing it to space. Although it has a considerably smaller impact on global temperatures, greenhouse gases also speed up the pace at which the environment can collect short-wave radiation emitted by the Sun.
More heat from the Sun is being trapped in our atmosphere thanks to the accumulation of CO2 that is emitted after the combustion of fossil fuels. Human-made acts are referred to as anthropogenic actions, and the emission of CO2 is one such anthropogenic activity that adds to the current heightened greenhouse effect.
A greenhouse gas's contribution to the greenhouse effect is determined by how much energy it absorbs, how much it reflects back, and how much of it is present in the atmosphere.
Therefore the correct option is D.

Answers
Yes, the distribution of chlorophyll, stomata, mesophyll cells, and vascular bundles supports photosynthesis.
Let us discuss each separately.
Chlorophyll: It absorbs light energy from the sun, which is essential for photosynthesis. The distribution of chlorophyll within the mesophyll cells ensures that it is positioned optimally to capture sunlight.Mesophyll cells: Mesophyll cells are the main site of photosynthesis in plant leaves. It contains chloroplasts and provides a spongy texture to the leafy surface.Stomata: Stomata are small openings on the surface of leaves that regulate gas exchange, including the uptake of carbon dioxide (CO2) required for photosynthesis and the release of oxygen (O2) produced during photosynthesis. Vascular bundles: Specialized tissues composed of xylem and phloem, responsible for transporting water, minerals, sugars, and other substrates throughout the plant body.To know more, refer to;

Identify from which region of the vertebral column each vertebrae belongs to. What are the differences between the size of the body, vertebral foramen, and spinous processes?
Answers
Within the various regions of the spine, the vertebrae vary in size and shape, but they all follow similar structural patterns.
What is spine?Your spine, or backbone, is the central supporting structure of your body. It connects different parts of the musculoskeletal system. The spine helps us sit, stand, walk, twist and bend. Back injuries, spinal cord disorders, and other problems can damage the spine and cause back pain. The spine is the central supporting structure of our body. The spine is a chain of bones, but it is made flexible by elastic ligaments and intervertebral discs. The vertebrae are generally numbered and divided into different regions. Neck, chest, lumbar, sacrum, coccyx. Only the top 24 bones are movable.To learn more about spine from the given link :

Picture 1 is a part of cervical vertebrae and picture 2 is a part of thoracic vertebrae.
What is cervical and thoracic vertebrae?
The C1–C7 vertebrae, which make up the cervical spine (neck area), are connected to one another by intervertebral discs. These discs provide the spine with mobility and serve as shock absorbers when people are moving around.There are 12 vertebrae in the thoracic area, identified as T1–T12. Spinal nerves emerge through a space created by the intervertebral discs, laminae, pedicles, and articular processes of neighboring vertebrae. Combined, the thoracic vertebrae form a kyphotic curvature.Difference between size of the body, vertebral foramen and spinous processes:
Regardless of body size, nearly all mammals have seven cervical vertebrae. This indicates that there are significant differences in the size of cervical vertebrae, ranging from the shrew's relatively short cervical vertebrae to the giraffe's neck's much lengthened vertebrae. Each cervical vertebra in a fully mature giraffe measures 11 inches in height.The spinal cord and its meninges are located in the vertebral foramen. The spinal cord is located in this spacious passageway that runs up and down inside each vertebra; it is commonly referred to as the spinal canal rather than the vertebral foramen.The lumbar spinous processes (LSP) provide a crucial anatomical and biomechanical purpose by anchoring the interspinous and supraspinous ligaments, as well as the intersegmental paraspinal muscles and safeguarding the neuronal structures in the spinal canal.Hence one is cervical vertebrae and the other is thoracic vertebrae.

The correct pairings of terms with examples are:
B. Genotype: dominant
C. Phenotype: Bb
Understanding Genotype and PhenotypeGenotype refers to the genetic makeup or combination of alleles in an organism, and dominant is a term used to describe an allele that is expressed in the phenotype when present. Therefore, the term "dominant" is correctly paired with the example "Genotype."
Phenotype refers to the observable physical characteristics or traits of an organism. In this case, "Bb" represents a specific combination of alleles for a particular trait, which can be expressed in the phenotype. Thus, the term "Phenotype" is correctly paired with the example "Bb."

The influx of sodium ions causes the membrane to further depolarize. As this occurs, this will trigger the potassium ion channels to open, and potassium will flow out of the cell. At the peak of the action potential, the calcium ion channels open.
