Can someone help with this I don’t get it???

Answer:
For this specific star, it would be magnesium
Explanation:
when you look at the spectrum of light for, in this case, a star, you are seeing a specific light signature, like a fingerprint. you have to compare the black lines of the star's light spectrum to the light spectrum of different gasses to see which ones match up. in this case, the lines in star 8's spectrum match the lines in the spectrum of magnesium.

Explanation:
The primase enzymes produce RNA molecules; the enzyme is a type of RNA polymerase. Primase does its functions by synthesizing short RNA sequences. These short RNA sequences are complementary to a single-stranded piece of DNA, which serves as its template. Primers must be synthesized by primase enzyme before DNA replication can occur.

he created two laws of inheritance. How is a
scientific law formed?
Answers
Answer:
A scientific law is formed when the results of an experiment generate the same results every time a particular experiment is performed. A scientific law is made when something has been thoroughly tested again and again through experimentation. Unlike the theory, a scientific law is not subjected to change with time. A scientific law is accepted universally and other hypothesis can be generated based on the authenticity of the law.
Final answer:
A scientific law is formed through a process of repeatable, empirical observations over time. It is a clear and concise statement predicting certain phenomena derived from defined patterns in data. Mendel, for instance, formulated the laws of inheritance based on predictable patterns he observed in his study of pea plants.
Explanation:
A scientific law is typically formed through the process of repeatable, empirical observations over time. These observations are then formulated into a clear and concise statement that can predict certain phenomena. For example, in the case of Mendel, he observed the inheritance patterns of pea plants through several generations and formulated his laws: the Law of Segregation and the Law of Independent Assortment. Each of these laws was derived from clear patterns he observed in his data over time. Once these patterns became predictable and repeatable, they formed the basis for the scientific laws.

A pond fills with organic matter during eutrophication.
Explanation:
Eutrophication takes place when an environment like aquatic environment in the form of lakes, ponds, sea etc is filled and enriched with organic matter and nutrients.
This is a huge concern for aquatic or marine organisms as the excess nutrients give rise to algal bloom due to production of huge amounts of phytoplanktons. These phytoplanktons will use and deplete the reserves of oxygen present in the water, leaving very little or none for other aquatic or marine organisms. This leads to destruction of such organisms which require oxygen to survive and finally their endangerment and extinction.
Natural eutrophication occurs due to gradual and slow sedimentation process occurring over very long periods of time.
Artificial or man-made eutrophication due to sedimentation of organic waste from solid wastes, industrial effluents increases the nutrient content like nitrogen in the water bodies resulting in rapid and mass eutrophication disturbing the entire ecological system.
A pond fills with organic matter when "pond ages from oligotrophic to mesotrophic".
Explanation:
The ponds are basically ranging from youngest to oldest in the given categories: Oligotrophic, Mesotrophic, or Eutrophic phases of live. The oligotrophic ponds are known as fresh or young waterbody. Oligotrophic bodies are low in nutrient quantities, like nitrogen and phosphorus, so donot encourage algae and aquatic plants productivity. The middle ages mesotrophic aquatic bodies are carrier of more nutrients and thus more readily the development of plants and algae take place than oligotrophics, but less than eutrophic production. As aging take place from oligotrophic to mesotrophic, the pond sides continue to slope less and the base of the pond starts to fill in with organic matter.

Answer:
One common neurotransmitter is dopamine. It is an excitatory neurotransmitter that is involved in movement, learning, attention, and emotion. GABA is another common neurotransmitter, and it is a major inhibitory neurotransmitter. It is involved in anxiety, arousal, and sleep. Glutamate is a major excitatory neurotransmitter, and it is involved in learning and memory.
Acetylcholine: Serves as a messenger between each motor neuron and skeletal muscles, which accounts for its role in helping to control skeletal muscles.
Serotonin: Affects sleep, hunger, mood, and arousal; connected to aggression and abnormal behavior
Norepinephrine: Helps control arousal and alertness; helps in regulating mood
Endorphins: Major excitatory neurotransmitter; linked to memory and learning processes; released in response to pain and intense exercise
