Explanation:

1) The male frogs croak to attract mates. They can also visually attract females by displaying vibrant colors. They compete by comparing who calls louder

2) This aids in survival because this ensures that only healthy frogs get to pass down their genes. Unhealthy frogs will not be selected by females. This is called sexual dimorphism

3) The hummingbird displays its impressive tails which they move around to attract females. They may perform aggressive movements against other competing males.

4) These strategies are very important to maintain a diverse and healthy population in a community of animals.

Explanation:

Answer: The body systems that are involved are:

--> Nervous System and

--> muscular system.

Explanation:

The body is made up of different organ systems which usually works together to bring about proper functioning of the living organism. Examples of the body systems includes:

--> The nervous system: This system enables the animal to detect and respond to stimuli rapidly.

--> The muscular system: This system enables the organism to move from one location to another.

Both the nervous system and the muscular system work together to bring about coordination of activities. When you step on a tack and jeck away, sensory receptors detects stimuli from the external environment and pass the information received as an electrical impulses to the brain through the nerve fibres. The information is processed in the central processing region which is the brain.

The effectors such as the muscles goes into action upon receiving nerve impulses from the brain. Such actions includes muscular contractions which helps you to pick up the tack and put it on your desk.

Answer:

Heat

Explanation:

 Contact metamorphism happens when hot magma or lava comes into contact with rocks, causing a small area to change into a metamorphic rock. Contact metamorphism will be present on the outside edges of igneous intrusions.

Heat and/or pressure causes the metamorphism of an igneous rock into a metamorphic rock.

Metamorphic rocks refer to as some other type of rock, but have been substantially changed from their original igneous, sedimentary form. Metamorphic rocks formed when rocks are subjected to high heat, high pressure, hot mineral fluids or, more commonly, some combination of these factors.

Contact metamorphism occurs in rock exposed to high temperature and low pressure, as might happen when hot magma invades into or lava flows over pre-existing protolith. This combination of high temperature and low pressure generates numerous metamorphic facies.

Answer:

E. coexistence through resource partitioning.

Explanation:

An ecosystem can be defined as the natural living habitats of both living and non-living organisms, in which they interact with one another. Essential services such as plant pollination, water purification, nutrient cycling etc that are being provided by the ecosystem are really very vital, important and useful for the sustenance of life, both for humans and enhances social welfare.

An experiment can be defined as an investigation which typically involves the process of manipulating an independent variable (the cause) in order to be able to determine or measure the dependent variable (the effect).

This ultimately implies that, an experiment can be used by scientists to show or demonstrate how a condition causes or gives rise to another i.e cause and effect, influence, behavior, etc in a sample.

In this scenario, an ornithologist (scientist that scientifically study birds) observed two species of nuthatch, in which both species forage for insects on the same trees; one of the species forages in the upper canopy while the other forages in the lower canopy. Thus, this is probably an example of coexistence through resource partitioning.

Resource partitioning refers to the situation in which different species coexisting in the same environment are able to use available resources differently without interspecific competition among them. Thus, these specifies are able to coexist while staying out of each other's path; no disturbance by one species to the other.

A calico cat is a domestic cat of any breed with a tri-color coat. The calico cat is most commonly thought of as being typically 25% to 75% white with large orange and black patches (or sometimes cream and grey patches); however, the calico cat can have any three colors in its pattern.

Answer:

Chromosomes contain genes, which help to determine an organism's traits. Genes come in alternate forms called alleles. The actual gene combination that an organism receives from its parents is called its genotype, while the trait that gets expressed as a result is referred to as its phenotype. If an offspring receives the same type of allele for a given gene from each parent, it is said to be h o m o z y g o u s. If the alleles differ, it is h e t e r o z y g o u s.
