Can someone define tropism and describe the different types of tropism exhibited in plants?
Answer:
Hello.
Tropism is specific to the direction of the stimulus. Plants can either display a negative or positive movement in response to a stimulus. It is positive tropism when the movement is towards the direction of stimuli while it is negative tropism when the movement is away from the stimuli.
Tropism is a response to certain stimuli. A positive tropism is moving towards the stimuli, while a negative tropism is moving away from a stimuli.
Positive Phototropism - Growing towards light
Negative Phototropism - Growing away from light
Positive Thigmotropism- Moving towards touch
Negative Thigmotropism- Moving away from touch
Positive Hydrotropism - Growing towards water
Negative Hydrotropism - Growing away from water
Positive Gravitropism - Growing towards ground
Negative Gravitropism - Growing upwards

Binary fission can sometimes be advantageous in evolutionary processes, allowing new daughter cells to adapt to different environments.
Which of the following MOST LIKELY leads to a possible advantageous change during binary fission?
Possible answers:
A= DNA Replication
B= Crossing over
C= A mutation
D= Meiosis
Answer:
C
Explanation:
DNA replication should copy the DNA exactly, so should not produce any changes to the DNA sequence.
Crossing over does not occur in prokaryotes, it only occurs in eukaryotes. The same is true for meiosis, it does not occur in prokaryotes as it is a specialized type of cell division that creates gametes in multicellular organisms
Mutations create changes to the DNA sequence. By chance, occasionally these changes can be beneficial and give the new cell an evolutionary advantage. For example resistance to antibiotics, or an ability to digest a new nutrient.

Why is it important to aquatic life (in ponds and lakes) that water freezes top down?
Answer:
If ice were to form from the bottom of a lake or pond upwards, all life in that water would eventually freeze and die. Freezing of water from the top down is critical for aquatic life to survive in brutally cold winters, since surface ice actually helps insulate and slow the cooling of the water below.
When a biosphere resource is used up faster than it can be replaced, it is because
A it is a natural resource.
B it can be replaced in a short amount of time.
C the resource forms very quickly.
D the resource forms very slowly.
The statement (B) is correct. Biosphere can be replaced in a short amount of time.
What is biosphere?The biosphere, also known as the ecosphere, is the worldwide sum of all ecosystems. It can also be termed the zone of life on Earth. The biosphere is virtually a closed system with regard to matter, with minimal inputs and outputs.
Moreover, the biosphere is the region of the earth that encompasses all living organisms: plants, animals and bacteria. It is a feature that distinguishes the earth from the other planets in the solar system.
Therefore, the portions or regions where organisms are found are collectively called the biosphere. Thus, it can also be said that the biosphere is the sum of all the ecosystems on Earth.

A species of squirrels were split in half when a tornado swept through the forest.
Half of the squirrels ended up in an environment near a pond. The other half ended up on rocky ground. They were too far apart to reunite. Ten years later, both of the squirrel populations' allele frequencies had changed to be more fit for their environments. The pond squirrel population and the rocky ground squirrel populations could no longer mate together.

MONOCULTURE AND THE FOOD SUPPLY
In 2011, scientists announced that the Cavendish banana, the banana that most frequently makes it to American consumers, could be wiped out by a fungus if the fungus reached fields in Latin America where the banana is grown. It had happened before with the Gros Michel banana, which was wiped out between 1906 and 1960 and is no longer grown by farmers. The reason for scientists' concern: monoculture.
Monoculture is a practice common among farmers. In most fields, you will find a single crop and these plants are not very genetically diverse. This means they are less able to adapt to environmental changes and less able to fight off diseases. Many scientists are concerned that the practice of monoculture farming means that many crops, including bananas, may be subject to total loss or even extinction.
Heirloom Plants
One way that scientists think that food supplies can be protected is by using heirloom plants. An heirloom plant is a plant that was once grown by farmers but is not used in modern monoculture farms. Many heirloom plants are more genetically diverse than modern varieties, which mean they are better able to adapt to environmental change. They are also more likely to survive an attack by a pest or infection by a disease or fungus. However, heirloom plants usually do not produce as much food as modern varieties do.
Organic Farming
Organic farming combines older agricultural practices with modern practices and does not involve the use of synthetic materials such as manmade fertilizers and pesticides. It relies on scientific knowledge about the interactions among organisms and about natural materials that can be used to fertilize plants and control pests. Organic farming does not generally involve monoculture, and an organic farm will have many different kinds of crops. Organic farming practices usually reduce the chance of total crop loss, but like heirloom plants, organic farms are often less productive than conventional farms in terms of volume of food.
Genetically Modified Organisms
Genetically modified organisms, or GMOs, are organisms that have been genetically engineered by people. Many scientists think that concerns over the risks of monoculture can be alleviated by directly changing the genes of crops. They argue that the crops can be given resistance to pests and disease, can be modified to withstand drought, and can be engineered to produce more food. However, many people are concerned about the safety of GMOs, so they are highly controversial. The technology is new and involves the use of bacteria to insert genetic material, so people are concerned that the organisms may negatively affect human health.
Because of what scientists have learned about monoculture, they are:
not pushing for a change in farming.
asking for legislation mandating GMOs.
suggesting ways to protect food supplies.
telling farmers they need to grow fewer kinds of crops.
Answer: suggesting ways to protect food supplies
