There are different types of channels for blood flow that transport the blood pumped by the heart. They greatly differ only in the size of their diameters. Arteries are the big ones that are located mostly near the heart. Veins are the next which is where nurses inject you to gather blood. Then, the smallest ones are the capillaries.
Answer:
The most appropriate tissue to join the pubic symphysis -that provides resistance to pressure and stretch during childbirth- is fibrocartilage.
Explanation:
Options for this question are:
- <em>A. Fibrocartilage.</em>
- <em>B. Elastic cartlage.</em>
- <em>C. Bone.</em>
- <em>D. Hyaline cartilage.</em>
Fibrocartilage is made up of dense connective tissue rich in type I collagen fibers, hyaluronic acid and proteoglycans, which give it resistance to stretching and pressure.
Some ligaments are formed by fibrocartilage, in addition to the intervertebral discs and the junction of the pubic symphysis, allowing a certain degree of mobility to the associated structures due to their semi-elastic properties.
Hyaline cartilage, also made up of connective tissue, is less resistant than fibrocartilage.
Bone cannot form this junction, because it would not allow the relative mobility of the joint.
The elastic cartilage allows for stretching but not the strength needed to join the pubic symphysis.

Photosynthesis is a process used by plants and other organisms to convert light energyinto chemical energy that can later be released to fuel the organisms' activities. This chemical energy is stored in carbohydrate molecules, such as sugars, which are synthesized from carbon dioxide and water – hence the name photosynthesis, from the Greek φῶς, phōs, "light", and σύνθεσις, synthesis, "putting together".[1][2][3] In most cases, oxygen is also released as a waste product. Most plants, most algae, and cyanobacteria perform photosynthesis; such organisms are called photoautotrophs. Photosynthesis is largely responsible for producing and maintaining the oxygen content of the Earth's atmosphere, and supplies all of the organic compounds and most of the energy necessary for life on Earth.[4]
Although photosynthesis is performed differently by different species, the process always begins when energy from light is absorbed by proteins called reaction centresthat contain green chlorophyll pigments. In plants, these proteins are held inside organelles called chloroplasts, which are most abundant in leaf cells, while in bacteria they are embedded in the plasma membrane. In these light-dependent reactions, some energy is used to strip electrons from suitable substances, such as water, producing oxygen gas. The hydrogen freed by the splitting of water is used in the creation of two further compounds that serve as short-term stores of energy, enabling its transfer to drive other reactions: these compounds are reduced nicotinamide adenine dinucleotide phosphate(NADPH) and adenosine triphosphate (ATP), the "energy currency" of cells.
In plants, algae and cyanobacteria, long-term energy storage in the form of sugars is produced by a subsequent sequence of light-independent reactions called the Calvin cycle; some bacteria use different mechanisms, such as the reverse Krebs cycle, to achieve the same end. In the Calvin cycle, atmospheric carbon dioxide is incorporatedinto already existing organic carbon compounds, such as ribulose bisphosphate(RuBP).[5] Using the ATP and NADPH produced by the light-dependent reactions, the resulting compounds are then reducedand removed to form further carbohydrates, such as glucose.
Answer:
It's slowing down because of the time increase
Explanation:
As shown by the graph, as more time passes, the velocity slowly decreases. This means that as the time goes on, the car is slowing down.
