With Biogeographical evidence we know that animals spread and did what to their environments to enhance survival?
Answer:
Biogeographical evidence can tell us a lot about how animals have interacted with their environments over time. For example, by studying the distribution of different species and their habitats, we can learn how animals have adapted to different environments in order to enhance their survival. Some examples of this include animals developing specialized physical adaptations to help them survive in different environments, such as thick fur to stay warm in cold climates or long legs to run quickly in open areas. Additionally, animals may have changed their behavior in order to better survive in their environments, such as forming social groups to defend against predators or cooperating with other species to find food. Overall, biogeographical evidence can provide valuable insights into how animals have evolved and adapted over time in order to survive and thrive in their environments.

Explanation:
concentric rings around the central canal
The central canal known as the osteonic (haversian) canal is surrounded by concentric rings (lamellae) of matrix that make up the osteon.
A single layer of columnar ependymal cells lines the central canal, also known as the spinal foramen or ependymal canal, which runs from the conus medullaris in the lumbar spine to the caudal angle of the fourth ventricle. It depicts a piece of the original neural tube's lumen.
Along the spinal cord's length, there is a hollow tube called the Central Canal. The cerebral spinal fluid, a colourless fluid that surrounds the whole central nervous system as well as different channels and chambers inside the central nervous system, is what fills this route.
Concentric circles are those that share a common centre but have differing radii. It is described as two or more circles with the same centre, in other words. The area between two concentric circles with different radii is known as an annulus.

How many syllables are there in each line of a traditional haiku?
The haiku is a three-line Japanese poem with seven syllables in the second line, five in the first, and five in the third.
haiku is a poetic form without rhyme that has 17 syllables and is written in three lines of 5, 7, and 5 syllables each. Although it did not become known as a haiku until the 19th century, the haiku first appeared in Japanese literature in the 17th century as a snappy response to elaborate poetic traditions.
Writers of haiku have traditionally focused on expressing empathetically suggestive vistas into natural phenomena. The 17th-century poet Bash popularized this method, many of whose haiku reflected his own emotional state when interacting with nature. Haiku subjects expanded beyond natural themes after the 19th century.

What is the difference between arteriosclerosis and Arteriolosclerosis?
Arteriosclerosis is the result of the accumulation of lipids, cholesterol, and other materials in and on the arterial walls. a buildup of cholesterol plaque in the artery walls that prevents blood flow. Arteriolosclerosis is the term used to describe the thickening of arterioles, especially when it is related to systemic arterial hypertension.
When the arteries—the blood channels that transport oxygen and nutrients from the heart to the rest of the body—become thick and stiff, blood flow to the organs and tissues may occasionally be restricted. This condition is known as arteriosclerosis. Flexible and elastic arteries indicate good health. However, the artery walls can stiffen over time, a phenomenon known as arterial hardening.
The term "arteriolosclerosis" refers to the histologic alterations that are frequently observed in the aged brain's deep penetrating tiny arteries, such as intimal degradation, smooth muscle degeneration, and fibrohyalinotic thickening of arterioles with subsequent narrowing of the arterial lumen.

Which is true of a positive feedback loop?
A. It causes products of a reaction to increase the reaction, moving away from equilibrium.
B. It only occurs in plants.
C. It helps the characteristic stay at equilibrium.
Answer: A. It causes products of a reaction to increase the reaction, moving away from equilibrium.
Explanation: In a natural system, a positive feedback loop magnifies or worsens the impacts of a little disturbance or change, which then cause the system to react. Each input and output in a biological system is a result of and contributes to a specific occurrence. A biological phenomenon known as a feedback loop occurs when a system's output either amplifies the system (positive feedback) or suppresses the system (negative feedback). The ability of feedback loops to help living things maintain homeostasis makes them crucial. The mechanism known as homeostasis helps us maintain a reasonably stable internal environment that is neither too hot nor too cold, neither too hungry nor too sleepy. Depending on the type of organism and the environment it lives in, different levels of energy are required to keep an organism in a state of homeostasis.

What is the correct chronological order of the 3 steps of translation from mRNA to a polypeptide?
The translation of an mRNA molecule by the ribosome into a protein occurs in three stages: initiation, elongation, and termination.
The process by which a cell manufactures proteins using genetic information supplied by messenger RNA in biology. mRNA is produced as a result of DNA replication, and the information it carries guides the cell on how to link amino acids together to generate proteins.
After the process of transcription of DNA to RNA in the cell's nucleus, ribosomes in the cytoplasm or endoplasmic reticulum create proteins. Transcription is the process of transcribing DNA to RNA, while translation is the process of utilizing RNA to make proteins.

The digestive tract tissue consists of the Enteric Nervous System (Myenteric plexus, Submucosal plexus, and Parasympathetic ganglion of myenteric plexus), Esophageal Gland, and Blood Vessels.
The wall of the digestive tract is made of four layers of tissue. From the lumen of the digestive tract outward, these layers are:
1. Mucosa consists of the stratified squamous epithelium to facilitate the transport and absorption of digestive products; lamina propria in the form of sparse connective tissue; and the muscularis mucosae.
2. Submucosa consists of sparse connective tissue with lots of blood and lymph vessels; submucosal plexus (Meissner) as a regulator of digestive blood flow and controlling the function and secretion of epithelial cells; and lymphoid glands.
Another function of lymphatic nodules in the lamina propria and submucosa layers is as the body's defense system against virus and bacterial infections.
3. Muscularis consists of a layer of muscles for the independent movement of the mucous layer which then pushes and mixes food in the digestive tract; myenteric plexus (Auerbach) as a regulator of relaxation and contraction of the digestive wall; and blood and lymph vessels.
The myenteric plexus and the submucosal plexus regulate muscular contractions forming the parasympathetic ganglia which are the main components of the Enteric Nervous System.

Digestion is the process by which food is broken down into smaller molecules so that the body can absorb and use the nutrients. It is an incredibly complex process that involves a variety of steps.
One of the most important steps in the digestive process that represents a chemical change in food is the churning of food, liquids, and digestive juices in the stomach. The stomach is lined with a thick layer of muscle that helps to churn the food and mix it with digestive juices.
The churning of food, liquids, and digestive juices in the stomach is an important step in digestion that represents a chemical change in food.
