Answer: If plants grow in soil containing worms, then plant growth will be greater, because worms help decompose organic matter
Explanation: just did it and got it right
If plants are grown in soil containing worms, then they will develop strong and healthy because worms provide the necessary elements to the soil by degrading organic matter.
What is a hypothesis?
A hypothesis is a scientific conjecture, not verified, that requires corroboration. It is a possibility, but not a fact.
A hypothesis must express what is expected to occur in a perfectly comprehensive manner. There must be a logical relation between variables. It must be objective.
There are different kinds of hypotheses: descriptive, correlative, differentiative, or causative.
In this example we need to consider how the presence of the worms affect the bean plants development.
The variables are the presence of worms and the plants' development.
Hypothesis:
If plants are grown in soil containing worms, then they will develop strong and healthy because worms provide the necessary elements to the soil by degrading organic matter.

The correct answer is "Human activities have become the major cause of global change".
Explanation:
The missing options of this question are:
A) Humans are the most numerous species on Earth.
B) Humans live in all habitats where life exists.
C) Human activities have become the major cause of global change.
D) Human activities are achieving the goal of maintaining the Anthropocene indefinitely.
The correct answer is option C) "Human activities have become the major cause of global change".
The Anthropocene is a period of time that more than be dated by an historical event, is identified on a geological perspective by the time at which human activity was of significant impact on Earth's geology and ecosystems. This impact include climate change, affected mainly by the concentrations of carbon dioxide in the atmosphere. For instance, it is reported that in pre-industrial times the concentration of carbon dioxide in the atmosphere was of 280 parts per million (ppm), while by 2014, it is reported that it rose up to 400 ppm.
Do you think Biotechnology can be used in anyway in a case where someone has been bit by a venomous snake? If so how?
Answer:
Snake biting is a major public health problem for low-income countries. Till now only antiserum derived from animals are use for the treatment against snakebite venom.
But there are many innovation in biotechnology to manufacture antivenoms against venomous snake. Some of the innovations are as following:
Use of DNA immunisation techniques: In this technique, horses are immunised with toxin-encoding DNA and then antivenom is prespraed from their DNA.Recombinant antivenoms: in this technique antibodies in the animal-derived antivenom are replaced with recombinant human version and then entivenom will be prepared by cell cultivation.These innovation in biotechnology for the preapartion of antivenoms are easier to produce and more cost-effective.

How can photosynthesis be related to cellular respiration?
-What's produced (made) by one is needed (the reactants) for the other.
-They both produce the same products.
-They both have the same reactants (need the same things).
-These two processes have nothing in common.
Answer:
These two processes are related because what's produced by one is needed for the other.
Explanation:
In photosynthesis, O2 and glucose are produced. Autotrophs (and heterotrophs too) use cellular respiration to make carbon dioxide and water from organic compounds - glucose - and oxygen; therefore, we can say that the glucose and oxygen are acting as reactants in the process of cellular respiration.
Photosynthesis can be related to cellular respiration because What's produced (made) by one is needed (the reactants) for the other.
What is photosynthesis and cellular respiration?Photosynthesis is a process by which plants produce oxygen and energy in the form of carbohydrates by combining sunlight, water, and carbon dioxide.Cellular respiration is a series of metabolic reactions and activities that occur within organisms' cells to transform chemical energy from oxygen molecules or nutrients into adenosine triphosphate (ATP) and then release waste products (CO2).How are Photosynthesis and cellular respiration interrelated?A significant link exists between photosynthesis and cellular respiration. The reactants of one process are the products of another. It's worth noting that the equation for cellular respiration is the total opposite of the equation for photosynthesis:Photosynthesis: 6CO2 + 6H2O → C6H12O6+ 6O2
Cellular Respiration: C6H12O6 + 6O2 → 6CO2 + 6H2O
Photosynthesis produces the glucose required for cellular respiration and the production of ATP. After that, the glucose is converted to carbon dioxide, which is subsequently used in photosynthesis. During photosynthesis, water is broken down to generate oxygen, but during cellular respiration, oxygen is mixed with hydrogen to form water. Cellular respiration requires oxygen produced by photosynthesis and releases carbon dioxide, whereas photosynthesis requires carbon dioxide and releases oxygen.

How can we recognize non-renewable resources and work to preserve them as long as possible?
Which of the following isn't a type of renewable
energy?
geothermal
wind
nuclear energy
water
Answer:
Nuclear Energy
Explanation:
Geothermal, or using the earth's heat, is renewable, as the world will continue to produce heat until it is gone, in which case, we will be gone too.
Wind, is renewable, for it is part of Earth's cycle, and there will always be wind.
Water is renewable, because of the water cycle, in which water will always be returned to the earth.

Renewable sources of energy are those who can be replenished although it's all over. Those sources of energy which are not renewable, should be used judiciously in order to save something for future generation.
Here, Geothermal energy is the heat released by earth by different means. Since, There are several more years for the Earth to die, It will never stop forming geothermal energy. Wind is the part of Cycle in Earth, So it will not finished anytime until The earth dies.Water evaporates and again comes back to earth by the process of hydrological cycle. Hence, There is very little chance of losing water, it can be replenished again. So,Appropriate Answer:-

When we extracted our own DNA last Friday, how did the things we used (Gatorade, alcohol, soap) relate to the things that are used in this virtual lab?
Answer:
Soap solution functions to dissolve the cell membranes, alcohol is used to precipitate DNA, and Gatorade is a isotonic solution.
Explanation:
In the DNA extraction protocols, the cell membranes that are formed by lipidic bilayers can be dissolved by using detergent solutions that are functionally analog to soap solution, shampoo, etc. On the other hand, alcohol enables to precipitate DNA (because DNA is not soluble in alcohol), while proteins and other cellular components remain in the extraction solution. Finally, Gatorade is a isotonic solution that may be used to prevent the cells from lysing.

Describe what happened to the average yearly temperature on earth from 1970 to 1990. Give one possible reason why this change occurred.
Explanation:
In the given question, the graph has been shown representing the change in temperature on Earth between 1900 to 1990. The graph has been made by plotting temperature ( °F) on y-axis vs Year on the x-axis.
From the graph, it can be observed that the temperature on Earth has increased over the years but between 1970 to 1990 the temperature has increased from 56.9 °F to 58.1 °F approximately.
The reason for this increase in temperature could be accounted to the fact that the burning of fossil fuels like petrol, gas, coal and others increased over these years which increased the amount of carbon dioxide and other harmful gases in the atmosphere.
Due to the increase in these gas, the greenhouse effect was observed and the temperature of the Earth begins to rise at an alarming rate.

Explanation:
A carrot would be an example of a _______ system. The apical meristem and new growth in the roots are protected by the _______. Stems of _______ contain a ring of vascular tissue, which includes the xylem and phloem. Stems thicken to support plants growing taller during _______ growth. _______ regulate the exchange of gases in the leaves and help maintain homeostasis. The leaves are often broad and flat because they are the main site of _______ in a plant. The force that allows water molecules to stick to other water molecules is called _______. The process by which plants release water into the air as vapor, while pulling more water upward into the leaves is called _______. Respond to the following based on your reading. Explain, in your own words, the role of cohesion and adhesion in plant transpiration. What are several adaptations that leaves have undergone? Why do leaves have adaptations in different parts of the world? Choose three nutrients and explain how a plant may look if it has a deficiency in those nutrients.
Answer:
taproot
root cap
dicot
secondary
Stomata
photosynthesis
cohesion
transpiration
Cohesion describes water molecules sticking together, while adhesion allows them to stick to the sides of the xylem that runs up the plant stem. When water at the top of this chain breaks free and evaporates from the leaf, it pulls on the water molecules behind it. In this way, water molecules are pulled up the plant stem from the roots and into the leaves.
Leaves have adaptations such as broad or narrow widths, rounded or pointy tips, and straight versus many vertices. These adaptations allow different species of plants to optimize water retention and photosynthesis in different climates (in other words, cloudy, sunny, rainy, dry).
Answers will vary based on the three nutrients selected. Here is a model response: Plants can show many different deficiencies based on their nutrients. An iron deficiency will result in yellowing or brittle leaves. A potassium deficiency causes leaves to turn yellow at the edges and phosphate deficiencies cause plants to have darker green than normal leaves.
Explanation:
A carrot would be an example of a taproot .
stomata regulate the exchange of gases in the leaves and help maintain homeostasis.
The leaves are often broad and flat because they are the main site of photosynthesis in a plant.
The force that allows water molecules to stick to other water molecules is called hydrogen bond .
The process by which plants release water into the air as vapor, while pulling more water upward into the leaves is called transpiration.
The role of cohesion and adhesion in plant transpiration ?Cohesion and adhesion draw water up the xylem. Transpiration draws water from the leaf. Negative water potential draws water into the root hairs. Cohesion and adhesion draw water up the phloem.
Several adaptations that leaves have undergone?They are adapted for photosynthesis by having a large surface area, and contain openings, called stomata to allow carbon dioxide into the leaf and oxygen out.
Why adaptations of plants in different habitats occur?Plants adapt or adjust to their surroundings. This helps them to live and grow.
What are the 3 most common nutrient deficiencies in plants?
The nutrients most commonly deficient in plants are phosphorus, nitrogen, and iron.
Nutrient deficiency symptoms occur as yellowing of leaves, interveinal yellowing of leaves, shortened internodes, or abnormal coloration such as red, purple, or bronze leaves.
