Answer:
As I think second option is the correct one.
Explanation:
The myofibrils are made up of thick and thin myofilaments, which help give the muscle its striped appearance. The thick filaments are composed of myosin, and the thin filaments are predominantly actin, along with two other muscle proteins, tropomyosin and troponin.
Ouch. You step on a tack and jrk away without even thinking. Then you decide to pick up the tack and put it on your desk. Which body systems are involved?
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.
An ornithologist has observed two species of nuthatch that appear to live in similar environments: both species forage for insects on the same trees, but one species forages in the upper canopy, and the other species forages in the lower canopy. This is probably an example of A. territorial competition leading to competitive exclusion. B. territorial competition leading to niche overlap. C. Both A and C are correct. D. intraspecific competition that leads to habitat separation. E. coexistence through resource partitioning.
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.

Which of the following describes an impact of floods on ecosystems?
Answer:
Soil erosion.
Explanation:
Soil erosion is the impact of floods on ecosystems because the floods moves very fast which takes soil with itself. Due to soil erosion, the productive layer of the soil or the layer in which nutrients are present are eroded which has a negative impact on the plants due to unavailability of nutrients. The floods moves very fast and the soil has no the ability to hold its particle tightly which leads to erosion of the soil that negatively affected the ecosystem.

Identify ONE process that causes the metamorphism of an igneous rock into a metamorphic rock.
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.
What is 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.

Please answer this, ITS IMPORTANT AND I NEED ASAP!!!
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.

Which of the following mixtures forms a solution?
A. melting ice
B.
sand and water
C. boiling water
D. alcohol in water
Answer:
D. alcohol in water
Explanation:
All the other answers do not form a solution. Melting ice, as well as boiling water, is still pure water. Sand and water are two different substances, however, sand does not dissolve in water to create a homogeonous solution, leaving alcohol and water, which DO combine into a homogeonous solution.

Which best explains why all of the Earth’s freshwater is not available for human use?
Answer:
2.5% of the earth's fresh water is unavailable: locked up in glaciers, polar ice caps, atmosphere, and soil; highly polluted; or lies too far under the earth's surface to be extracted at an affordable cost.
Explanation:
99% of liquid freshwater on Earth is Stored as Ground water
Much of it probably isn't accessible to us Human.
About 71 % of Earth is covered in water, and the Ocean holds most of it but this is salt water, almost all fresh water is stored underground

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.
