Tropism can be defined as the movement of plants in response to an external stimuli.
Tropism is a term which is used to describe how a particular plant responds to an external stimuli by growing, turning or moving towards or away from it. When the movement of plant is towards the stimulus, it is known as positive tropism and when the movement is away from the stimulus it is known as negative tropism.
For example, phototropism is the movement of a part of the plant in response to light. When the movement of plant occurs towards the light, it is known as positive phototropism and when it occurs away from it, it is known as negative phototropism.

Answer: the creation of oxygen
Explanation:
took the K12 Quiz (Note: not to sure its right if it aint so so sorry!)
A family business had bred dogs for over 250 years. During this time, 125 generations of dogs were bred for a single trait: protective instincts. Immediately after
birth, the puppies are sorted based on whether or not they have a white patch of fur on their chests. Those without this trait, are no longer bred for their
business and instead are adopted to pet stores and not private sales for people requesting the desired trait of protective instincts.
How could the breeders know these other dogs will not have the traits they are looking for when they are just new-born puppies?
Answer:
They can know if the trait has been carried on by looking at the bred dogs that have the trait and determining if the trait has been passed down by similar characteristics between the parent with the trait and the puppy that could have the trait.

Which statement below best explain the difference between microevolution and macroevolution
A. Biodiversity (macroevolution) is a result of natural selection whereas microevolution studies changes due to extinction
B. Natural selection (microevolution) focuses on a adaptation change within a species whereas macroeveolution studies similar features among species
C. Evolution (both micro & macro) takes thousands or millions of years; however, due to the complexity of DNA- microevolution usually takes longer.
D. Microevolution explains how new & different species evolve from natural selection and Macroevolution studies the different anatomical features from the DNA mutations.

4. Which statement is an example of how
environmental factors affect gene expression?
A. Your finger becomes callus from writing with a
pencil
B. The amounts of sun, water, and nutrients affect the
growth of a plant
C. Parents with red hair have a child with red hair
D. A red snapdragon flower is crossed with a white
snapdragon flower to produce a pink snapdragon flower.
Answer:
B. The amounts of sun, water, and
nutrients affect the growth of a plant
Explanation:
Gene expression is the way by which the genes of an organism instructs the production of proteins, which are responsible for the organism's phenotype. However, the trait or characteristics possessed by organisms are not strictly or 100% dependent on the genotypic factors but also on the environmental factors.
Environmental factors are the biotic (living) and abiotic (non-living) factors that affect organisms development and growth. An example is how the amount of sun, water, and nutrients, which are all environmental factors, affect the growth of a plant. Growth in plant, therefore, affects gene expression.

#1
Possibly one of the most evolved sharks today are hammerhead sharks. They have an advanced sensory system and a body shape that has adapted to hunt specific prey
#2
Sharks may be one of the most important species on Earth. They have been maintaining our oceans for over 400 millions years.
#3
Sharks have evolved and changed much over millions of years. However many sharks today still share some of the features as sharks from millions of years ago.
#4
Sharks have been in our oceans for over 400 million years. Some of the earliest sharks were discovered dating back to the Devonian age.
#5
Sharks have survived five massive planet extinction events. These extinction events killed most life on earth and the last one around 65 million yeas ago killed the dinosaurs.
#6
There are over 500 species of shark.
#7
It is believed that each whale shark's pattern is unique, like a human's fingerprint.
#8
Sharks do not have bones. Instead, they have cartilage, that's what makes up human noses and ears
#9
According to the Smit.hsonian, there are over 500 known shark species, though many are endangered or declining due to various factors like overfishing.
#10
Your odds of getting attacked and killed by a shark are 1 in 3,748,067. In a lifetime, you are more likely to die from fireworks or lightning. Whereas over 100 million sharks are killed every year by humans.
#11
Whale sharks are the world’s biggest fish.
#12
Sharks mature slowly and reach reproductive age anywhere from 12 to 15 years.
#13
Hammerhead sharks' eyes are on the sides of their heads, so they have nearly a 360-degree sight line. Their panoramic view of the undersea world is inhibited by two blind spots, one in front of the snout and the other directly behind the head.
#14
Sharks predate the dinosaurs by 200 million years.
#15
Great whites can detect one drop of blood in 25 gal (100 L) of water and can sense even tiny amounts of blood in the water up to 3 mi (5 km) away.

What evidence from the study supports the hypothesis that dogs might use a magnetic sense to navigate?
Answer:
Yes.
Explanation:
Yes, a new research indicates that dogs might use a magnetic sense to navigate. Dogs has world class nose which helps them to navigate to their destination but it also has a magnetic compass that helps them in navigation. The dogs use magnetic field of the earth to find out shortcut ways in the unknown land or terrain so the hypothesis is right that dogs used magnetic sense for navigation.

Gregor Mendel, a 19th century monk, used pea plants to arrive at several conclusions
about how traits are passed on to offspring. One conclusion became known as the Law of
Segregation. The illustration below shows how this law operates.
Parent 1
Parent 2
Offspring 1 Offspring 2 Offspring 3 Offspring 4
Which conclusion can you make based on Mendel's work as shown in the diagram?
Parent 1 has the dominant trait
Parent 2 has the dominant trait.
The offspring inherit traits only from Parent 1.
The offspring will not pass on the trait, inherited from Parent 2, to their offspring.

B
Explanation:
Neurons that respond to specific types of lines are examples of:
A. figure detectors.
B. top-down processors.
C. feature detectors.
D. figure processors.
Answer:
C
Explanation:
Neurons that respond to certain types of lines are examples of feature detectors found in Option C. Neurons are the monomeric units of the nervous system that play an important role in transmission.
What is the importance of the neuron?
The neuron is a unit in which the message is transmitted from the neuron to another neuron, and this can be done by either chemical signaling or by electric signaling. The neuron receives sensory stimuli from the sensory organ and transmits them to the spinal cord.
Later, the message from the spinal cord is sent to the motor organs, and the whole pathway of the neuron signaling from the sensory to the motor organ is called the reflex arc. The neuron takes part in the signaling process so that the muscle can function, regulate the contraction relaxation, and perform many other functions.
Hence, neurons that respond to certain types of lines are examples of feature detectors found in Option C.

respiration is a ____________ reaction on which sugar is oxidized to produce energy
Answer:
chemical
Explanation:
Respiration is a redox reaction on which sugar is oxidized to produce energy .
What is respiration?Cellular respiration is a sequence of chemical events that break down glucose to produce ATP, which can then be utilized as energy to power a variety of reactions throughout the body. Glycolysis, the citric acid cycle, and oxidative phosphorylation are the three basic processes that take place during cellular respiration.
Animals and humans use breathing to get the oxygen they need for cellular respiration. In order to create ATP, the nutrients you absorb through food must be broken down by the oxygen you breathe, while carbon dioxide and water are generated as waste products.

Context and regional metamorphism
Foliated
Non foliated
Answer:
Metamorphic rocks started out as some other type of rock, but have been substantially changed from their original igneous, sedimentary, or earlier metamorphic form. Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors.
