Answer:
Science is a process that involves proof and error. Scientific hypotheses are used to find evidence supporting scientific statements, but new evidence can be used to reject previously accepted ones in order to get closer to the truth.
Explanation:
Scientific inquiries refer to the processes by which scientists study phenomena of the natural world and propose alternative explanations (hypotheses) useful for understanding such mechanisms. When hypotheses are supported by many evidence and studies from different sources, scientific theories associated with these hypotheses become accepted by the scientific community. In science, a scientific statement may become falsifiable when it is contradicted by new lines of evidence and/or new observations.

How are spring tides different from Neap Tides. Give at least 2 reasons _______
Answer:
Seven days after a spring tide, the sun and moon are at right angles to each other. This produces moderate tides known as neap tides, meaning that high tides are a little lower and low tides are a little higher than average. Neap tides occur during the first and third quarter moon, when the moon appears "half full.

What do memory B and T cells do when they encounter a pathogen for the second time?
Answer: When B cells and T cells are first activated by a pathogen, memory B-cells and T- cells develop.
Throughout the lifetime of an animal these memory cells will “remember” each specific pathogen encountered, and are able to mount a strong response if the pathogen is detected again. This type of immunity is both active and adaptive.
Active immunity often involves both the cell-mediated and humoral aspects of immunity as well as input from the innate immune system.

How much has the greenhouse gas carbon dioxide increased in the air just in the last few years? ITS DUE IN A FEW HOURS PLEASE HELP!
Answer:
approximately 2.3 parts per million (ppm) per year
Explanation:
In 2019, the global amount of atmospheric carbon dioxide (CO2) has been estimated at approximately 410 parts per million (ppm). These levels are higher than at any time in the last 800,000 years, and it has been estimated that in 2025 the CO2 levels will be higher than at any time in the last 3.3 million years. In 2018, there has been an increase of approx. 2.5 ppm, the same increase observed between 2017 and 2018. Moreover, the average increase of the CO2 levels in the atmosphere between 2009 and 2018 was 2.3 ppm each year.

According to the passage, which of the following topics of study was the most crucial to his final analysis?
The study of statistics and probabilities
The study of plant varieties
The study of agriculture
His study of the experimental method
Answer: The study of plant varieties.
Explanation:
This question relates to the studies that Gregor Mendel, founder of modern genetics, performed at the University of Vienna.
Experimenting on pea plants, Gregor Mendel was able to establish a lot of the rules of heredity that we know today even though his research was not fully appreciated or understood during his own life.
He credited the study of plant varieties to have been most crucial to his final analysis because farmers had been crossbreeding varieties for millennia to bring about better traits in plants.

What does the field of proteomics study? The structure and function of cellular lipids and how they interact to contribute to traits. The structure of carbohydrates and how they are converted into a useable form of energy for the body. The interaction between cellular proteins and how they make up the bulk of the cell membrane. The structure and function of cellular proteins and how they interact to contribute to traits. The structure of prions and how they can lead to various diseases within the body.
Answer:
The structure and function of cellular proteins and how they interact to contribute to traits.
Explanation:
Proteomics is a research area that studies proteomes and their interactions with other cellular components (e.g., transcription factors involved in DNA-protein interactions, ribonucleoprotein complexes involved in RNA-protein interactions, etc). A proteome can be defined as the entire set of proteins synthesized by an organism. The proteomics field allowed us to identify common protein functions (structural and enzymatic functions), as well as understand how protein expression (which is regulated by genetic and environmental factors) influences cellular metabolic activities (e.g., iron uptake).
