charles darwin predicted the existence of a moth with a very long "tongue" after he discovered a species of night-blooming flowers with extremely long, tube-shaped blooms. About 50 years after Darwin died, such a moth was discovered. Apply lesson concepts to explain the basis for Darwin's prediction.
The prediction of Darwin depends on the sizes of both the moth's tongue and the tube of blooming flowers.
What do you mean by Species?Species may be defined as a group of organisms that can reproduce naturally with one another and create fertile offspring.
The moth's long tongue helps them to take the nectar from the tube of blooming flowers which are also very long. In this situation, the moths that possess long tongues survive in both conditions whether the tube of blooming flowerers is short or long.
This same concept was also predicted by Charles Darwin. The long tongue of the moth gives them the advantage in every situation of the tube's length.
Therefore, the prediction of Darwin depends on the sizes of both the moth's tongue and the tube of blooming flowers.

Marine debris is very harmful to marine life. - not an answer choice
1 Its effect, however, is only limited to marine creatures, as it does not affect birds and other species that depend on the sea.
2 One of the major contributors to marine debris is plastic.
3 Garbage and litter from the beach do not contribute to marine debris. Research shows that marine debris is likely to decrease over time as plastics degrade into smaller particles.
4 New methods of manufacturing have been adopted to reduce material consumption and thus prevent a larger contribution to marine debris.

a red flower and a white flower can be expressed on a plant, depending on genetics. which outcome would indicate codominance as the inheritance pattern for flower color in this species?
Answer:
A phenotypic outcome that would indicate codominance woul be if the flowers produced had both red and white petals or had red and white colour expressed at the same time.
Explanation:
Codominance is when two phenotypes both show up in the resultant offspring. The most common rexample for codominance is roan cattle or animals with spotty patterns that can have browns, blacks and white simlutaneously. So if the red and white phenotypes both appeared (and the petals of the flower had red and white but were not a mix of red and white-ie pink flowers would be incomplete dominance-) then this would indicate codominance was an inhereitance pattern of the flower species.

The bone labeled D in the diagram is the femur.
What is femur ?The femur is the longest and strongest bone in the human body, located in the upper leg or thigh. It articulates with the pelvis at the hip joint and with the tibia and fibula bones of the lower leg at the knee joint. The femur is responsible for supporting the body's weight, allowing for movement, and protecting the organs in the pelvic region.
The femur is divided into several sections, including the head, neck, shaft, and condyles. The head of the femur is a spherical structure that articulates with the acetabulum of the pelvis to form the hip joint.
The neck of the femur is a short section that connects the head to the shaft. The shaft of the femur is the long, straight part of the bone that extends from the neck to the condyles. The condyles of the femur are the rounded surfaces at the bottom of the bone that articulate with the tibia and fibula to form the knee joint.
The femur is composed of two types of bone tissue: compact bone and spongy bone. The compact bone is located on the surface of the bone and provides strength and protection, while the spongy bone is located in the interior of the bone and provides shock absorption.
Injuries to the femur can be serious and require medical attention. Fractures of the femur can occur due to high-impact accidents or falls, and may require surgery to repair.

A river separates members of a squirrel population that used to occupy the same geographical area, Thus, option "2" is correct.
What is Allopatric speciation?Allopatric speciation is said to occur when two groups of organisms are separated by a physical or geographical barrier. Examples of such barriers are ocean, mountain range, rivers, etc. A good example of allopatric speciation is Galapagos finch.
Different species of this bird can be found in different islands at Galapos, which is located at Pacific Ocean off South America. The ocean is barrier that isolate the species from one another.

1. What is a limiting factor?
a variable that causes population growth to speed up
O
a variable that causes population growth to increase
a variable that causes population growth to slow
a variable that limits maximum total food availability
A limiting factor is a variable that causes population growth to be slow.
It is a variable of a system that causes a noticeable change in output or another measure of a type of system.
A limiting factor is a variable that causes population growth to slow down. Hence the correct option is B.
In ecology, limiting factors are environmental factors or resources that restrict the growth, abundance, or distribution of a population or species in an ecosystem. These factors can be biotic or abiotic. Biotic limiting factors include competition for resources, predation, and disease, while abiotic limiting factors include factors like temperature, water availability, nutrient availability, and sunlight.
When a population experiences a shortage or restriction in essential resources, it cannot grow at its maximum potential, leading to a slowdown in population growth. Limiting factors play a crucial role in regulating population dynamics and maintaining ecological balance in natural ecosystems. By understanding limiting factors, ecologists can gain insights into how ecosystems function.
Hence the correct option is B.

All wetlands are considered freshwater ecosystems.The given statement is false.
What is ecosystems?
An ecosystem is a community of living organisms and their physical environment, interacting as a system. It includes all the living things (biotic factors) in a particular area, as well as the non-living things (abiotic factors) such as air, water, and soil. Ecosystems can be small, such as a pond, or large, such as a rainforest, and are interconnected through various ecological relationships. The health of an ecosystem depends on the balance and interdependence of its components.
The statement is false. While many wetlands are freshwater ecosystems, some wetlands can also be saline or brackish ecosystems depending on their location and surrounding environment. For example, mangrove swamps and salt marshes are wetlands that are typically found in coastal areas and have a high salt content. Therefore, wetlands can be either freshwater or saline ecosystems.
