Providing long-term control over the body's internal conditions
Keeping conditions within a normal range
Adjusting the "set point" for body temperature based upon level of activity
Answer:
Explanation: Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways. This variation means that some individuals have traits better suited to the environment than others.
Answer:
Grassland
Explanation:
Healthy grasslands are important habitats for birds and other wildlife, and also places where we farm and ranch. They provide food, cover, space and safe access to water for both wildlife and livestock.
The order in which the earliest organisms evolved -
- Archaea and bacteria
- Protists
- Fungi and shell-less invertebrates
- Green algae
- Shelled Invertebrates
On the earth, various kinds of organisms evolve at different geological times, and on their evolution, they consider the oldest or youngest organisms:
- Archaebacteria and bacteria was the oldest living organism on earth was, they lacked a membrane-bound nucleus and cell.
- The protists evolved after the bacteria, they were multicellular prokaryotic organisms.
- Fungi and the shell-less invertebrate, much-developed organisms in terms of body organization and structure. These have membrane-bound, well-defined cell membranes, and a nucleus. They even had a tissue level of organization.
- Green algae evolve after protists which belong to the division Thallophyta of the plant kingdom. These are photosynthetic as they have chlorophyll in the cell.
- Shelled Invertebrates are the youngest organisms that evolved recently among these.
Thus, the correct order is -
- Archaea and bacteria
- Protists
- Fungi and shell-less invertebrates
- Green algae
- Shelled Invertebrates

Answer: 77.0J
Explanation:
The magnetic field is given as 4.40T
Since the volume is not given, we assume that the volume is 10.0cm³
We need to find the magnetic field energy in this volume.
The energy density is:
u = B²/2u•
u• is given as 4π × 10^-7 T.m/A
Using this formula we substitute
u = B²/2u• = (4.40 T)²/ 2(4π × 10^-7 T.m/A) = 7.704 × 10^6 J/m³
The energy is equal to the energy density multiply by the volume. You get;
U= uV = (7.704 × 10^6 J/m³) × (10.0 × 10^6m³) = 77.0J
