i need 2 paragraphs about which is better between organic food or gmo
Answer:
Most commonly found in crops such as soybeans, corn and canola, GMOs are designed to provide a higher nutritional value to food, as well as protect crops against pests. Organic foods, on the other hand, do not contain any pesticides, fertilizers, solvents or additives.
Organic is non-GMO because the use of GMOs is prohibited in organic production. For example, organic farmers cannot plant GMO seeds, organic livestock cannot eat GMO feed, and organic food manufacturers cannot use GMO ingredients.
From a health perspective, GMO food is no different than non-GMO food. In fact, they can even be healthier. Imagine peanuts that can be genetically engineered to reduce levels of aflatoxin, and gluten-free wheat, which would give those with celiac disease a healthy and tasty bread option
GMO foods are as healthful and safe to eat as their non-GMO counterparts. Some GMO plants have actually been modified to improve their
Use the map below to answer the following question:
Map of Europe and North Africa labeled, Spread of Christianity. Dark green indicates Christian areas, 325 AD. The dark green areas are small, isolated patches surrounding the Mediterranean Sea. Light green indicates Christian areas added by 476 AD. Most of Spain, Gaul, Italy, Greece, and Asia Minor are light green. The light green extends to the European inland, and as far north as parts of Great Britain. It also extends to part of Egypt, Syria, and the North African Mediterranean coast. A grey line indicates the boundaries of the Roman Empire, 476 AD. This line extends around the Mediterranean, from North Africa in the south, beyond Jerusalem to the east, and into northern Gaul.

Oxygen is released from the red blood cells into the:
A) Tissues
B)Lungs and exhaled
C)white blood cells
D)Bone marrow
Protein found in red blood cells that carries oxygen
O A. positive Rh factor
O B. luminol
O C. plasma
O D. hemoglobin
Answer: hemogoblin
Explanation: Red cells contain a special protein called hemoglobin, which helps carry oxygen from the lungs to the rest of the body and then returns carbon dioxide from the body to the lungs so it can be exhaled. Blood appears red because of the large number of red blood cells, which get their color from the hemoglobin. Please give me brainliest :)

When did the mass extinction occur? (Name the era and period)
Answer:
Explanation:
The first mass extinction is called the Ordovician-Silurian Extinction. It occurred about 440 million years ago, at the end of the period that paleontologists and geologists call the Ordovician, and followed by the start of the Silurian period. In this extinction event, many small organisms of the sea became extinct.
Answer:
at the beginning of this era
Explanation:
The diagram reveals that lipids and proteins are both parts of cell membranes. They have different functions because lipids work to А remove nucleic acids from the cell membrane, and proteins work to hold the cell membrane together. B hold the cell membrane together, and proteins move chemicals across the cell membrane. С stiffen the cell membrane, and proteins create fibers that attach to the ends of the lipids. D move chemicals across the cell membrane, and proteins work to store water in the cell membrane.
Answer:
There is no diagram in this question but the question can still be answered without it.
B. hold the cell membrane together, and proteins move chemicals across the cell membrane
Explanation:
The fluid mosaic model, which describes the structure of the cell membrane, reveals that it contains both lipids and protein constituents. These components, however, performs different functions in the cell membrane of organisms.
The lipid component of the cell membrane, which comprises of glycolipids and cholesterol, hold the cell membrane together while proteins called transport proteins help move chemicals across the cell membrane.

Describe the structure of vertebrate sensory organs!!!
Answer:
The vertebral column, or backbone, is made up of a series of repeating, or metameric, structures called vertebrae (singular, vertebra) that extend from the head to the tail along the dorsal (top) side of the body. The function of the vertebral column is to provide the central support structure of the endoskeleton, allowing an organism to hold its shape. It also serves to house and protect the spinal cord that that lies within the column.
What is the name of the approach to biological research that integrates data from multiple levels of complexity
Answer:
systems (system biology)
Explanation:
Systems biology can be defined as a methodology whose interest is to understand the high scale levels of complexity in biology (i.e. organism level, tissue level, cell function, etc) by integrating information/data from different sources, and thus examine the interaction between biological components. This approach is contrary to reductionism, which is another approach used in biology research. Therefore, systems biology is a holistic approach aimed at modeling complex biology systems by applying computational and mathematical methods, enabling to understand biological systems.

Could emigration or immigration have played a major role in determining the size of the reindeer
population? Explain. Think about where these reindeer were and whether they could swim that far
Answer:
Yes.
Explanation:
Yes, emigration or immigration have played a major role in determining the size of the reindeer population in specific area because immigration is done by the animals in search of food. The animals moves from one region to another in search of food so due to this movement the population of reindeer decreases in that specific area. Reindeer are good swimmers so due to this ability they cross the vast Yukon River which is half mile wide.

In guinea pigs, smooth coat(S) is dominant over rough (s) and black coat (B) is dominant over white coat (b). In the cross SsBb x SsBb, how many of the offspring will have a smooth black coat on average
Answer:
9/16
Explanation:
Smooth coat (S) is dominant over rough coat (s) and black coat (B) is dominant over white coat (b).
SsBb x SsBb
Offspring (You can also see the attached image for the Punnet's square analysis)
9 S_B_ = Smooth black coat
3 S_bb = smooth white coat
3 ssB_ = rough black coat
1 ssbb = rough white coat
Hence, on average, 9/16 of the offspring will have a smooth black coat

Fuel wood is particularly important in many developing countries, which leads to deforestation and overuse of many species trees. Brainstorm two ideas that could help to reduce fuel wood demand, and explain how your ideas would contribute to sustainability of forest resources.
Answer:
My ideas are the following:
1. Maintain clean cardboard and paper discards to be subsequently recycled
2. Reforest the degraded areas using native species with rapid generation times to be subsequently reutilized
Explanation:
In the home it is possible to sort waste materials, including cardboard and paper. These waste products are made of 100 % recyclable materials but only when they are clean. For efficient recycling purposes, it is therefore necessary to maintain clean both materials (for example, by removing plastics or other materials attached to cardboard and paper). Moreover, reforestation can be a sustainable and cost-effective method for protecting native trees in developing countries. In these countries, economic issues may hamper the adoption of reforestation techniques, thereby new areas may be deforested to obtain more fuelwood. To solve this problem, it is possible to reforest vast areas by using native trees that exhibit rapid generation times, which may then be used as an alternative source of sustained raw material.

What is the main difference between food chains and food webs?(1 point)
A. Food webs are more complex than simple food chains.
B. Food chains focus on energy transfers, but food webs do not.
C. Food chains focus on the internal energy cycles of animals, unlike food webs.
D. Food webs do not show connections between animals like food chains.
Question: "What is the main difference between food chains and food webs?"
Answer: "The best way to analyze this question would be to compare the two diagrams; when looking at a food chain, it is much easier to understand as to easily seeing the organism on the bottom (start) and the top (end) of the food chain, depending on its ecosystem. However, a food web on the other hand branches off into more complex details of every living thing connected to each other and how their roles effect the 'web'. So, this being said, I would say out of the options given above, Option A is the best choice."
Among the microbes responsible for producing fermented foods, the two most prominent groups are the lactic acid-producing bacteria and yeasts that produce _________.
Answer:
Alcohol
Explanation:
Fermentation is a type of anaerobic respiration employed by organisms like yeast and certain species of bacteria. As stated in this question, YEAST and the BACTERIA that produces lactic acid as a product are the two major microbes that undergoes this fermentation process.
However, YEAST (a unicellular fungus) undergoes fermentation to yield alcohol and CO2 as its product. Yeast breaks down sugar molecules into ethanol (C2H5OH) and carbon dioxide (CO2) in its cells enabling it to be used in the production of fermented foods like cheese, beer etc.
Compare and contrast the cell membrane with the cell wall. *
Explanation:
For one, the cell wall is found only in plant cells, as it needs more protection. The cell wall is also found in the cells of plants, fungi, and bacteria. It can also be found rigid or smooth.
The cell membrane is found in both plant and animal cells. It controls what enters and leaves the cell. It surrounds the cytoplasm of the cell.
You have isolated a highly lethal toxin from an octopus that you have reason to believe binds with high affinity to the pore opening of a voltage-gated sodium channel. To determine the effect of toxin binding, you perform a _______ experiment.
Answer:
To determine the effect of toxin binding, you perform a Competitive Binding Experiment
Explanation:
Competitive binding experiments are very relevant when matters relating to cellular and or molecular toxicity are concerned.
They are used to determine the binding of a single concentration of labeled ligand in the presence of various concentrations of unlabeled ligand.
They are important because:
1. Validate a direct binding assay
2. Confirm whether or not a drug binds to the receptor
3. determine and explore how low-affinity drugs and receptors interact and it's resultant effects

Read the section "Seeds." Which sentence from the section states the main idea about seeds? A The life cycle of flowering plants begins with a seed. B The outside of a seed is called a shell. C The wind blows some, and others float on water. D The next phase starts when a seed gets someplace it can start growing.
Answer:
A The life cycle of flowering plants begins with a seed.
Explanation:
Seeds are structures found only in a group of plants called higher plants, comprising of gymnosperms and angiosperms. Seeds are the developed/fertilized ovules of a plant.
Seeds are basically the reproductive unit of the angiosperms, also called FLOWERING PLANTS i.e. plants that produce flowers (reproductive structures). This means that the life cycle of flowering plants begins with the germination of the EMBRYO in a SEED.
