Why is the scientific method so important in science
The scientific method attempts to minimize the influence of bias or prejudice in the experimenter.
Bias is a disproportionate weight in favor of or against an idea or thing, usually in a way that is closed-minded, prejudicial, or unfair. In science a bias is a systematic error.

A cell sends messages to itself via Autocrine Signaling
Autocrine signaling refers to the generation and extracellular secretion of a given chemical messenger that interacts with receptors present in the plasma membrane of the same target cell, thereby initiating a signal transduction pathway.An example of an autocrine signaling pathway is the production and secretion of the cytokine interleukin-1 (IL-1) pro-inflammatory cytokine in monocytes.Moreover, paracrine signaling is a type of signaling that occurs between local cells.Endocrine signaling is a type of signaling pathway that occurs between distant cells. This type of signaling is mediated by chemical messengers called 'hormones' which are released from endocrine cells and travel throughout the body.Learn more in:

What does a cell need to be a prokaryote cell?
please help me i’m stuck !!
Answer:
The Prokaryotic CellProkaryotes are unicellular organisms that lack organelles or other internal membrane-bound structures. Therefore, they do not have a nucleus, but, instead, generally have a single chromosome: a piece of circular, double-stranded DNA located in an area of the cell called the nucleoid.
Open-pit mining creates a large hole in the ground after minerals are removed from the surface. Which statement best describes an environmental consequence of this process?
Heavy metals are released into surrounding soil, poisoning local vegetation.
High salinity of wastewater reduces soil fertility and growth of vegetation.
Billions of gallons of water are pulled from surrounding ecosystems.
Wastewater is contaminated with oil and becomes sludge in landfills.
Answer: (A) Heavy metals are released into surrounding soil, poisoning local vegetation.
Explanation: Open-pit mining falls under the surface mining category in the lesson 01.07 page 3/8 under the affects of surface mining the only one that is in the multiple choice questionnaire is "Heavy metals are released into surrounding soil". (don't know how much this helps since I'm 7 days late but hey this is a new curriculum and I've had trouble finding answers on brainy so why not contribute for once ¯\_(ツ)_/¯ )
The correct statement that best describes an environmental consequence of open-pit mining is that heavy metals are released into the surrounding soil, poisoning local vegetation.
The large hole left by open-pit mining becomes filled with water during heavy rains with heavy metals dissolving in the water to form solutions.These solutions percolate the surrounding soil and when they are taken up by the vegetation on the soil, the plants become poisoned by the heavy metals.In other words, the hole created by open-pit mining serves as an avenue for heavy metals to get into the surrounding soil and gets into the food chain through the plants.

Compare and contract induction and deduction.
Answer:
Both deduction and induction are a type of inference, which means reaching a conclusion based on evidence and reasoning. Deduction moves from idea to observation, while induction moves from observation to idea. Deduction is idea-first, followed by observations and a conclusion.

What’s the answer of “The porous cross walls between sieve tube elements”??
Answer:
The xylem vessels and the phloem sieve tubes are connected end to end to transport the water and the food respectively to long distances in a plant. Their end plates are perforated to allow the easy passage of substances from one vessel and the sieve tubes.
Answer:
Sieve tube cells are placed end to end in phloem The end walls may be transverse or oblique They have many small pores called sieve pits Each sieve pit is lined by a layer of callose Excessive growth of callose closes the sieve pores Due to the presence of sieve pits the end walls are commonly called sieve plates

The body systems that would immediately get involved with my reaction to the cut are nervous system, circulatory system, integumentary system. That is option A
The systematic factors that are required for wound healing after sustaining a cut in the finger include:
The nervous system: here the nerve cells in the skin help wounds to heal. When an injury occurs, cells known as glial cells change into repair cells and disseminate into the wound, where they help the skin to regenerate.The circulatory system: The cut surfaces become inflamed and blood clot and cell debris fill the gap between them. Phagocytes from the blood stream, begins to remove the clot and cell debris stimulates fibroblast.The integumentary system: the skin contains extracellular matrix (ECM) which is made of collagen and elastic fibres that provide structure to the skin and are necessary for wound closure.Learn more here:

What similarities, if any, do you think exist between a human’s reproductive cycle and the life cycle of a fern? What differences, if any, can you think of?
Answer:
The similarity between ferns and humans is that both go through meiosis and mitosis. But ferns are different because they have multicellular, free-living haploid and diploid forms. In humans, the haploid stage exists in the form of single cells—sperm and eggs. Only the diploid stage that begins with a zygote grows mitotically to form a multicellular, free-living human.
Explanation:
Humans and ferns are similar as both of these organisms fertilize to reproduce while differs in the haploid form of life which is present in the ferns and the male and female reproductive parts present in humans.
What is the life cycle of a fern?
The life cycle of fern includes the diploid fern which gives rise to the haploid spores that grows and form a gametophyte plant in which both the male and female reproductive systems are present. The male gamete undergoes fertilization with the female gamete to form a diploid spore (seed) which gives rise to the new fern plant.
Human’s reproductive cycle include diploid animals and the male and female genders which can be distinguished clearly. The male gamete-sperm fertilizes with the female gamete-egg to form the diploid zygote that gives rise to a new human.
