The organs found in plants or animals is stem vascular. Therefore, option (D) is correct.
What are the features of the stem vascular?A stem is one of two main structural axes of a vascular plant, the other being the root. It supports leaves, flowers and fruits, transports water and dissolved substances between the roots and the shoots in the xylem and phloem, stores nutrients.
The vascular system of plants, complete with xylem and phloem, fills both purposes. Stems, along with roots, also store food for the plant. Pith, a tissue that lies in the center of the stem.
A vascular bundle is a part of the transport system in vascular plants. The transport itself happens in the stem, which exists in two forms: xylem and phloem.

Mass extinctions in across North America and Australia coincide with human migration. With our understanding of populations, which is most likely true about mass extinctions
Answer:
Mass extinction occur when the environment is not favourable.
Explanation:
Mass extinctions occur on the earth when there is sudden change in the environmental conditions for an organisms that is not good for the survival of that particular organisms so they extinct from the earth surface. The example of mass extinctions are dinosaurs. These dinosaurs were extinct due to change in their environment that decreases the availability of food for them so due to no available food, the dinosaur extinct from the earth.

Complete each sentence by dragging the proper word or phrase into the appropriate position. Then place each sentence in order of mobility beginning with the least mobile.1. When two bones join together and fuse so that no visible separation occurs, it is referred to as a(n) ____________ , or bony joint.2. Bones that join together and are held in place with threads of collagen, form a joint that is called a(n) ____________ .3. The most complex joints are called ____________ joints. They display varying amounts of mobility.4. Bones joined together with cartilage between the ends of the bones, form a joint called a(n) ____________ .1. amphiarthrosis2. suture3. gomphosis4. synarthrosis5. synostosis6. synovial
Answer:
1. When two bones join together and fuse so that no visible separation occurs, it is referred to as a(n) synostosis, or bony joint.
2. Bones that join together and are held in place with threads of collagen, form a joint that is called a(n) synarthrosis.
3. The most complex joints are called synovial joints. They display varying amounts of mobility.
4. Bones joined together with cartilage between the ends of the bones, form a joint called a(n) amphiarthrosis.
Explanation:
The ossification of the connective tissue between two bones results in the fusion of them. As a result, now there is one bone instead of two. It's is called synostosis.
A synarthrosis is a joint that has very little or no movement at all. It has threads of collagen around them that keep the joint together.
A synovial joint is a diarthrosis joint. They have a wide range of mobility and are complex due to the number of components:
A fibrous joint capsule connected to the two bones. A synovial membrane. Synovial fluid to lubricate the joint.Articular cartilage on the bones' joint surfaces.An Amphiarthrosis is a joint with limited mobility. This type of joint has fibrocartilage that connects the two bones. We can find it in the pubic synthesis.

it is estimated that you loose heat to cold water four times faster than to cold air. Your body is mostly water. What if your body had much less water in it, and the rest of it consisted of substances that heated and cooled as easily as metal. would a cold environment be more chilling or not?
Explanation:
Before explaining the following phenomenon, it is good to clarify one thing: the laws of thermodynamics are fulfilled and cold water usually freezes faster than hot water. However, and although it seems counterintuitive, it has been observed for centuries that this fact is not always fulfilled and under certain circumstances, hot water freezes before cold water. Aristotle was the first to record this phenomenon, but it was not published as a scientific observation until 1969 by Erasto Mpemba. Precisely due to the surname of the scientist born in British Tanganyika, this phenomenon is known as the Mpemba effect. A curious effect that has recently been having an impact due to a new viral called "boiling water challenge" and consists of throwing boiling water into the air to see how it quickly freezes and turns into snow.
Cold environment would be more chilling.
Water is an essential feature of homeostasis in an organism. Water increases the volume of blood, which affects blood pressure and heart rate. Water dissolves gases and allow for efficient exchange and transport of oxygen and carbon dioxide.What is homeostasis?Homeostasis is a self-regulating process by which biological systems maintain stability while adjusting to changing external conditions.This is the condition of optimal functioning for the organism and includes many variables, such as body temperature and fluid balance, being kept within certain pre-set limits.To know more about homeostasis here
