Coral reefs and kelp forests are both underwater ecosystems, but they are quite different from each other. Coral reefs are made up of tiny animals called coral polyps that secrete calcium carbonate skeletons, which build up over time to form the reef structure. Coral reefs are found in warm, clear, shallow waters in tropical and subtropical regions.
Kelp forests, on the other hand, are underwater forests made up of large, brown seaweeds called kelp. Kelp forests are found in cold, nutrient-rich waters in temperate regions. Kelp forests provide habitat for a wide variety of marine life, including sea otters, fish, and invertebrates.
Overall, coral reefs are characterized by their hard, rock-like structure and the diversity of colorful marine life they support, while kelp forests are characterized by their tall, swaying seaweed and the abundance of fish and other animals they attract.

you and your friend in the school yard. you rest your ear against a metal leg of the swings while your friend gently taps on the leg. you hear the tapping. describe the wave produced bt tapping. is it a longitudinal wave or a transverse wave? Draw a model of the wave.
The wave produced by tapping on the metal leg of the swings is a longitudinal wave. Longitudinal waves have oscillations that occur parallel to the direction of wave propagation.
When your friend taps on the metal leg, it causes compression in the material. This compression then travels through the metal as a wave, with successive compressions and rarefactions. As the wave reaches your ear, it causes your eardrum to vibrate, and you perceive the tapping sound.

3. Critique At lunch, your friend stated that her
apple was a living thing, because if she put a
piece under the microscope, she'd see cells.
How will you respond?
I would respond by acknowledging that indeed an apple does have cells, but that does not necessarily make it a living thing. While it is true that living things have cells, there are other criteria that must be met in order for something to be considered living.
Living things are characterized by their ability to grow, reproduce, respond to stimuli, and maintain homeostasis. An apple, on the other hand, does not have the ability to do any of these things. It cannot grow or reproduce, nor can it respond to stimuli or maintain homeostasis.
Additionally, while an apple does contain living cells, those cells are not actively carrying out the functions necessary for life. They are essentially in a state of suspended animation until the apple begins to decompose.
Overall, while it is understandable that someone might assume an apple is a living thing due to the presence of cells, a more comprehensive understanding of what constitutes life would lead one to conclude otherwise.

12. Describe evidence showing that echinoderms are more closely related to chordates than are other invertebrate phyla.
Every animal has specialized tissues and is a eukaryotic, multicellular entity.
Animal cells don't have a cell wall, in contrast to the cells of plants and fungi. Animal cells have flexibility as a result. It enables them to adopt various forms, so they can specialize to perform specific tasks.
Animals are born as eggs or living creatures, develop into adulthood, and then mate. Animals either hatch from an egg or are born as young, prepared for life.
The existence of a notochord, a dorsal, hollow nerve cord, and pharyngeal slits (also known as gill slits) are the four most notable traits that set chordates apart from animals in all other phyla.
Three key characteristics in the evolution of invertebrates are symmetry, specialization, and cephalization.
Cephilized invertebrates, which have brains, may also only have nerve nets.
Radial symmetry, in which body components are arranged around a central axis, and bilateral symmetry, in which organisms may be divided into two nearly identical halves along a single plane, are the two basic types of symmetry. A few organisms exhibit asymmetry, or complete lack of body plane symmetry.
The mouth, sense organs, and nerve ganglia get concentrated in the front of an animal over many generations, creating a head area. This is known as cephalization. This is connected to mobility and bilateral symmetry, resulting in a distinct head end for the animal.
The mesoderm, is a germ layer that emerges during gastrulation, found between the ectoderm, which will develop into skin and cells of the central nervous system.
The coelom, a cavity inside the body that is filled with fluid, acts as the organism's hydrostatic skeleton.
An organism can move across segments while having its delicate organs protected from harm. An organism's capacity to segment functions into various body parts enables it to carry out ever-more complicated actions and utilize various body parts for a variety of roles.
Since echinoderms are deuterostomes, they are linked to practically all other invertebrate phyla more distantly than they are to chordates, which includes ourselves.

Pancreatic islets are groups of cells found within the pancreas that synthesize hormones like insulin and glucagon. Testicles constitute male reproductive organs which produce testosterone, a key hormone for enhancing masculine features.
How to explain the partsSituated at the base of the brain, pituitary gland plays a pivotal role in producing as well as equilibrating the secretion of various hormones that affect other endocrine glands. Adrenal glands perched atop kidneys produce essential hormones - adrenaline and cortisol to meet stressful environments while reducing inflammation or immune response.
The thyroid presides over the neck region; its major function lies in generating notable hormones that help adjust metabolism including growth rates. On the other hand, ovaries serve as female reproductive organs responsible for estrogen production besides regulating other imbalances.
Hypothalamus, located centrally inside the skull, governs effective release and prompt regulation of hormones from the pituitary gland, consequently ensuring balanced activity within the body. Thymus is located close to the chest area, generally empowering stable maintenance and nourishment of healthy immune systems.
Pineal gland characterizes a smaller gland nested deeply inside the human brain tasked with furnishing the natural sleep cycles via melatonin hormone secretion. Parathyroid glands, comprising four small nodules attached around neck structure, effectively contribute to Calcium homeostasis by promptly releasing Parathyroid hormone into bloodstream when required.

Before Darwin's theories, scientists thought that species….
O never changed
O Changed over time
O Changed only randomly
Answer:
Never changed.
Explanation:
Before Darwin's theories, scientists thought that species never changed. This concept was commonly known as the doctrine of "fixity of species," which posited that species were immutable and remained unchanged since their creation. According to this belief, species were considered to be fixed entities with no potential for an evolutionary change or adaptation to their environment. This view was deeply entrenched in the prevailing scientific and religious beliefs of the time, and it was not until Darwin's groundbreaking work on natural selection and the theory of evolution that this long-held notion was challenged and replaced with the understanding that species do indeed change over time through the process of natural selection and other mechanisms of evolution.

One case of an natural condition that can be use as a selection agent for choosing the the most beneficial traits of a species to move into the next generation is the availability of nourishment.
How is availability of nourishment beneficial to traits of a species as a selection agent?Within the case of finches, the estimate and shape of their bills are vital for their capacity to get nourishment.
Assume there's a populace of finches living in an zone where the essential nourishment source comprises of hard-shelled seeds. Finches with bigger, more grounded snouts would be superior able to split open these seeds and get the supplements interior. Over time, this natural condition would act as a determination specialist, favoring people with bigger, more grounded snouts, and driving to the transmission of these useful characteristics to the another era.
So also, in case the essential nourishment source comprises of littler, milder seeds, finches with littler, more sensitive noses would be superior adjusted to get and devour this nourishment. In this case, the natural condition would select for people with littler, more sensitive snouts, and these characteristics would be passed on to future eras.
Other natural variables, such as climate, predators, and illness, can too act as choice operators and shape the advancement of a species over time.

The genetic variation of the smaller population will be reduced compared to the original population.
The vocabulary term that most specifically describes this form of genetic drift is the founder effect.
What happens to small populations overtime?Small populations are more liable to genetic drift, which can lead to loss of genetic variation and increase in frequency of certain alleles. This can reduce the genetic diversity of the population and increase its likelihood to inbreed, resulting in the expression of deleterious recessive alleles.
