Answer: Greenhouse gases arise naturally, and are part of the make-up of our atmosphere. Earth is sometimes called the “Goldilocks” planet – it’s not too hot, not too cold, and the conditions are just right to allow life, including us, to flourish. Part of what makes Earth so amenable is the naturally-arising greenhouse effect, which keeps the planet at a friendly 15 °C (59 °F) on average. But in the last century or so, humans have been interfering with the energy balance of the planet, mainly through the burning of fossil fuels that give off additional carbon dioxide into the air. The level of carbon dioxide in Earth’s atmosphere has been rising consistently for decades and traps extra heat near the surface of the Earth, causing temperatures to rise.

The internal systems of organisms and how materials circulate within organisms. Question 4 options: organ tissue Living System homeostasis
Answer:
Living System
Explanation:
Living system can be defined as the internal systems of organisms and how materials circulate within organisms.
Generally, these living systems are self-organized life forms and are known to be very much interactive with their surroundings or environment. Also, living systems are dependent on the flow of information, matter and energy at various levels.
Some examples of living systems in organisms are respiratory system, nervous system, digestive system, and circulatory system.
Additionally, living systems comprises of the following components; cells, organs, muscle, tissues, blood, etc.

What type of evolutionary mechanism did this story show?
Allele frequencies in a population may change due to four fundamental forces of evolution: Natural Selection, Genetic Drift, Mutations and Gene Flow. Mutations are the ultimate source of new alleles in a gene pool. Two of the most relevant mechanisms of evolutionary change are: Natural Selection and Genetic Drift.
This story showed an example of convergent evolution. Convergent evolution is the process whereby organisms that are not closely related independently evolve similar traits as a result of having to adapt to similar environments or ecological niches.
What is in the story ?In this story, the two species of birds, the crows and the jays, evolved to look similar as a result of living in the same environment and competing for the same resources.
The two species evolved to look similar in order to blend in with their environment, making it difficult for predators to distinguish them from one another. This allowed them to survive and thrive in the same environment.
Therefore, This example of convergent evolution is a perfect example of how species can evolve to look similar in order to survive in the same environment. It also shows how competition for resources can drive species to evolve similar traits in order to survive.

What do the two arrows represent?
A. Arrow 1 represents prophase, and arrow 2 represents interphase.
B. Arrow 1 represents mitosis, and Arrow 2 represent meiosis.
C. Arrow 1 represents interphase, and Arrow 2 represents mitosis.
D. Arrow 1 represents meiosis, and Arrow 2 represents prophase.
(You will find the cycle in the attached files)
Answer:
C. Arrow 1 represents interphase, and Arrow 2 represents mitosis.
Explanation:
When we talk about the whole cell cycle we are referring to the interphase and the cell division (mitosis or meiosis).
Interphase: Represented in the cycle by arrow 1.
The interphase is the previous step before mitosis occurs. The interphase is conformed of the G1, S, and G2 stages.
• During the G1 stage, it occurs a high intense biochemical activity. The cell duplicates its size, and the organelles and other molecules and cytoplasmatic structures duplicate too. Some structures, such as microtubules and actin filaments, are synthesized from zero. The endoplasmic reticulum increases in size and produces a membrane for the Golgi apparatus and vacuoles, lysosomes, and vesicles. During this stage, the pair of centrioles separate, and each centriole duplicates. Mitochondria and chloroplasts also replicate.
• During the S stage occurs the DNI replication process. At this point, also occurs the synthesis of histones and other associated proteins. This is the only stage where the DNI molecule is replicated.
• G2 stage is the final one before the cellular division. Here begins the slow process of DNI condensation. Duplication of centrioles completes. Structures such as spindle fibers are assembled.
Once the whole interphase is completed, mitosis occurs.
Mitosis: Represented in the cycle by arrow 2.
Mitosis is a process by which, from a diploid somatic cell (2n), two daughter diploid cells (2n) are produced. During mitosis, the cell separates. Mitosis is divided into four phases (these phases are shown in the cycle with different gray color tones). In the prophase, it occurs chromosomes condensation and nuclear membrane breaks. During the metaphase, fibers of the spindle apparatus capture chromosomes and take them toward the center of the cell, to the equatorial plane, where they line up. Each chromatid joins with a microtubule of opposites poles. Sister chromatids are held together until they reach the Anaphase, during which other enzymes are activated to break the bonds and separate the chromatids, which migrate to the opposite poles. In telophase, the duplicated chromosomes are already in the corresponding poles, and the nuclear membrane forms again in each pole. Finally, occurs cytokinesis.

What 2 chemicals are inside skeletal muscle?
Answer:
Skeletal muscle tissue is composed of cells called muscle fibers. When the nervous system signal reaches the neuromuscular junction a chemical message is released by the motor neuron. The chemical message, a neurotransmitter called acetylcholine, binds to receptors on the outside of the muscle fiber.
The 2 chemicals inside skeletal muscle are : i) Organophosphate ( OP ) and ii) Acetylcholine ( ACh )
The skeletal muscle is toxic in nature due to the presence of certain chemicals ( Organophosphate and Acetylcholine ). and this causes the skeletal muscle to experience some level of toxicity. some of the toxic effects caused by the presence of these chemicals in the skeletal muscle include :
weakness of the muscle.partial/complete paralysis.muscle hyperactivity.Hence we can conclude that the 2 chemicals that can be found inside skeletal muscle are Organophosphate ( OP ) and Acetylcholine ( ACh )

Craig rides a skateboard on the sidewalk in front of the mall, traveling at 18km/h. How much time would it take him to travel 6.0km?
I really need help, on learning how to slove this, there more to it than just d/t TxT
Answer:
0.33hours
Explanation:
The speed of a moving body can be calculated by using the formula;
Speed = distance ÷ time
According to the information provided, the time it would take Craig to ride the skateboard on the sidewalk at an average speed of 18km/h for a distance of 6km is being asked.
Hence, derived from the above formula;
Time = Distance/speed
Time = 6/18
Time (hr) = 0.3333hr or 19.8minutes
