What product has wheat flour as its substrate and yeast as the microbe? *
Answer:5
Explanation:
Wheat flour contains starch. The starch is hydrolysed to glucose. Glucose is used by yeast(saccharomyces cerevisae) to make ethanol.
C6H12O6(glucose from wheat flour)---(yeast)-->2C2H5O(ethanol)+2CO2
Ethanol is the main product

This is turned to bring the object being viewed closer.
Answer:
Revolving nosepiece
Explanation:
The revolving nosepiece (also called the turret) is the part of the microscope we can turn in order to view an object through different objective lenses. Objective lenses, which provide different levels of magnification (usually 4x, 10x, 40x, and 100x), are all attached to the revolving nosepiece. It allows us to switch lenses from those that provide less magnification to those that provide more. This is how we can see more details on an object we're observing.
You can see what this part of the microscope looks like in the image attached below:

What do we call the changing in magnetism as we move out from the center of a mid-ocean ridge?
Plate tectonic systems
Continental creep
Faulty ground flow
Magnetic reversal
Answer:
Continental Creep
Explanation:
The definition of Continental Creep is:
Continental drift is the hypothesis that the Earth's continents have moved over geologic time relative to each other, thus appearing to have "drifted" across the ocean bed. The speculation that continents might have 'drifted' was first put forward by Abraham Ortelius in 1596.

How could you decrease the amount of energy an object has?
The amount of energy that an object has can be decreased by decreasing its temperature.
Let us recall that the temperature of a body is a measure of the average kinetic energy of the molecules of the body. The molecules in a body are always in constant random motion.
The kinetic energy possessed by the body is dependent on its temperature. To control the amount of energy that an object has, we either increase or decrease its temperature.
If we want the amount of energy that an object has to decrease, we simply decrease its temperature.

nonvascular because it has spores
nonvascular because it has true roots
Spores

True roots
Answer:
It is vascular because it has true roots.
Explanation:
Vascular plants evolved true roots made of vascular tissues. Compared with rhizoids, roots can absorb more water and minerals from the soil. They also anchor plants securely in the ground, so plants can grow larger without toppling over.

xplain how the enteric nervous system supports the digestive system. What might occur that could result in the autonomic nervous system having a negative impact on digestion
Answer:
It controls gastrointestinal track.
Explanation:
The enteric nervous system supports the digestive system because enteric nervous system controls gastrointestinal track and there is no control of central nervous system (CNS) in this gastrointestinal track. Our gastrointestinal tract comprise of our mouth, esophagus, stomach, small intestine, large intestine, and anus. If abnormality occur in autonomic nervous system which result in negative impact on digestion because autonomic nervous system regulates digestion process.
Differentiate between weather and climate
Answer:
The term "weather" means the state of the atmosphere in a shorter period of time, while the term "climate" refers to how the atmosphere behaves in the long run.
Explanation:
When we talk about climate change, we are talking about long-term change.
"tTme" describes the way in which the atmosphere "behaves", which primarily means the effects that this "behavior" has on life. The biggest difference between climate and weather is that the term "weather" refers to extremely short-term changes in the atmosphere - so short that they are measured in minutes and months.

Roller coasters, with their twists, turns, and loops, seem to defy everything we know about how objects move. Roller coaster designers use Newton's laws to
push people past their usual limits. Which statement identifies Newton's Law of Motion with the correct justification of that law? (DOK 2, AKS 8b)
OA Newton's first law is the law of inertia. Since an object at rest stays at rest, all roller coasters have to be pushed or pulled to get started.
OB. Newton's first law is the law of force and acceleration. Since the rollercoaster is so massive, it will require more force to accelerate
OC. Newton's third law of action-reaction states that for every action, there is an equal and opposite reaction. This means that as you push down on the
seat, the seat does not push back on you with an equal force.
OD. Newton's second law is the law of force and acceleration. Since the rollercoaster is so massive, it will require less force to accelerate.

Sally is working on a farm and cuts her hand whilst opening a gate.
The cut becomes infected with bacteria that then invade the tissues of the finger.
The bacteria begin to multiply, each division doubling their number.
There are now too many bacteria for Sally’s immune system to cope with. The infection spreads.
Sally goes to the doctor to get some antibiotics. The doctor prescribes penicillin tablets and Sally begins to take the medicine. Many of the bacteria are killed by penicillin. Some bacteria however are naturally resistant to the antibiotic and so are not killed. These bacteria are said to be adapted to their environment.
The resistant individuals then multiply, increasing their numbers a million-fold in a day. Soon the antibiotic resistant bacteria become very common in the population. Sally’s infection is now very serious and will soon spread throughout her entire body. She returns to the doctor.
1. Does the antibiotic cause the resistance to the antibiotic?
2. In this example, how do you know that antibiotic resistance has a genetic basis?
3. What should the doctor now do to help Sally get better?

A population of the Galapagos finch Geospiza fortis undergoes directional selection for larger bill size after Geospiza fuliginosa colonizes the same island. This is an example of:
Answer: character displacement
Explanation:
Character displacement is an evolutionary change which happens in a scenario whereby two identical species live in same environment. When this occurs, natural selection takes place which then favors a divergence based on the characters that the organisms possess.
Therefore, when a population of the Galapagos finch Geospiza fortis undergoes directional selection for larger bill size after Geospiza fuliginosa colonizes the same island is an example of character displacement.

Gregor Mendel studied many things at the University of Vienna. According to the
passage, which of the following topics of study was the most crucial to his final
analysis?
Answer: It would be the study of different plant varieties.
Explanation:
The one topic which study was the most crucial to his final analysis is the study of plant varieties. The correct option is B.
Who was Gregor Mendel?Gregor Mendel discovered the fundamental laws of inheritance while working on pea plants. He deduced that genes are inherited in pairs and as distinct units, one from each parent.
Mendel studied the segregation of parental genes and how they manifested in offspring as dominant or recessive traits.
Mendel's First Law is particularly noteworthy because he made his observations and conclusions (1865) without having any prior knowledge of the relationships between genes, chromosomes, and DNA.
The law of segregation is the most important of these three laws because it has no exceptions and is universally accepted.
The study of plant varieties was the most important topic for his final analysis.
Thus, the correct option is B.
