Darwin's finches exhibit rapid ecological speciation and diversification as a result of rapid adaptation to an unstable and difficult environment. Their phenotypes now exhibit great diversity as a result of this.

Short beaks in Darwin's finches have been found to be an adaptation that makes them better adapted to grub feeding and poking holes in the ground. 3. Darwin's finches provide an illustration of how beak variation among finches was brought about by evolution selection. The development of a group of plants or animals into various species that are adapted to particular ecological niches is known as adaptive radiation, and the classic example is the Darwin's finches. The Galapagos finches contributed to the development of Darwin's theory of evolution selection. Until they all split off to become separate species, Darwin's Finches' advantageous characteristics were chosen for over many generations. These birds possessed distinct beaks, although being almost identical to mainland finches in all other respects. Divergent evolution was visible in the finches.

The statement that ‘Plants and animals adapt in order to survive in a hostile environment' is true because there are certain characteristics of plants and animals that were specifically developed to survive in their environment.

As environmental conditions change over time, organisms adapt structurally and behaviorally. Some desert plants have developed small, light-colored leaves with tiny hairs as a structural adaptation to conserve water.

Many desert animals change their behavioral patterns to become nocturnal for the same reason. Because of the structural adaptations made possible by our large brains and dexterous hands, humans have been successful in utilizing every ecosystem on Earth. This has allowed us to adjust our behavior to a wide range of environments.

For gas exchange and photosynthesis, plant leaves are designed. Through root hair cells, which are carried up the plant by the xylem, the roots absorb water and mineral ions.

These show that to be able to survive their environments, plants and animals have had to adapt to the environment.

Answer: Plates at our planet’s surface move because of the intense heat in the Earth’s core that causes molten rock in the mantle layer to move. It moves in a pattern called a convection cell that forms when warm material rises, cools, and eventually sink down. As the cooled material sinks down, it is warmed and rises again.

Explanation: Hope the explanation above was helpful

Answer:

Explanation:

For every ellipse E there are two distinguished points, called the foci, and a fixed positive constant d greater than the distance between the foci, so that from any point of the ellipse, the sum of the distances to the two foci equals d .

The stability and instability lean on the relationships between ‘nor­mal lapse rate’ and ‘adiabatic change of temperature’. Adiabatic rate is many times constant whereas normal lapse rate of air temperature changes.

When the normal lapse rate is higher than dry adiabatic rate, the air being warmer increases and becomes unstable. On the other side, when the normal lapse rate of temperature is lower than dry adiabatic rate, the air being cold descends and becomes stable.

Stability:

When dry adiabatic lapse rate of an ascending dry air is higher than the normal lapse rate and if it is not saturated and does not attain dew point it becomes colder than surrounding air at certain height with the result it becomes bulky and descends.

This process causes stability of atmospheric circulation due to which vertical circulation of air is resisted.

Instability:

When normal lapse rate is greater than dry adiabatic lapse rate of ascending parcel of air the increasing air continues to rise upward and expand and thus becomes unstable and is in unstable equilibrium.

Physical processes such as erosion, weathering, and tectonic activity can all contribute to the formation of lowland landscapes. Erosion is the process by which rocks and soils are worn away by the action of water, wind, and ice. This can create valleys, canyons, and other low-lying areas. Weathering is the process by which rocks are broken down by exposure to the elements, such as temperature changes, precipitation, and the effects of plants and animals. This can also create low-lying landscapes, as well as other features like cliffs and caves. Tectonic activity, which includes the movement of the Earth's crust, can also play a role in the formation of lowland landscapes by creating mountains and valleys.
