Tracking Changes to Your Trees and Woods: Measuring growth

In previous posts, we recommended that landowners get out into their woods to keep an eye on any changes that might be taking place, whether that be changes to the health of your trees or boundary problems. We also suggested you keep track of physical changes to your trees by watching them grow and change over time. First we gave you some tools to identify the trees in your woods. This month’s post will introduce ways you can measure the growth of individual trees.
You can measure the growth of individual trees over time by measuring their diameter. Many of us learned to count the rings of a tree to determine how old they are. The other secret in the rings of our trees is how wide they are. Generally, healthy, not crowded trees will put on more growth in diameter over time; thus, the rings will be wider when they are healthy. If you are astute, you may be asking how in the heck you measure the diameter of solid wood. That is where a handy tool comes into play, called the diameter tape. With this tool, you are technically using the circumference of the tree, and the number on the tape has markings that indicate the diameter (circumference divided by Pi (3.14)). You can purchase a diameter tape (D-tape) from forestry suppliers, or you can make your own using a simple length of rope or ribbon using the method shown in this publication . Trees tend to grow irregularly at the base, so to determine a more accurate measure of diameter, foresters will measure the diameter of the tree at 4.5 feet above the ground. When you record the diameter of trees, you can follow the growth of those trees over time, and you can calculate other important measures of your woods. As a reminder, healthy trees will grow faster (and fatter) in diameter each year than trees that are crowded and unhealthy.

Strawberry jelly is a very strong solution of sugar. By contrast the cytoplasm in bacteria is a much weaker solution. The cell wall of bacteria is made up of a PARTIALLY permeable membrane. Would water flow from the microbe to the jam, or from the jam to the microbe by osmosis? Explain
Since the concentration of the jelly is higher than the concentration of the bacterial cytoplasm, water would flow from the microbe to the jam by osmosis.
What is Osmosis?Osmosis is the movement of water molecules from a region of low solute concentration to a region of high solute concentration through a semi-permeable membrane.
The strawberry jelly is a stronger solution than the bacterial cytoplasm.
Therefore, water would flow from the microbe to the jam by osmosis.

The type of enzymatic regulation in which a substrate molecule binds to an enyzme thereby enhancing the catalytic activity of that enzyme is called.
The type of enzymatic regulation in which a substrate molecule binds to an enzyme enhancing the catalytic activity of that enzyme is called COOPERATIVITY. It increases enzymatic activity.
What is an enzyme?An enzyme is a protein that acts to lower the activation energy of a chemical reaction.
An enzyme has a specific catalytic activity, thereby shaping the conversion rate of reactants (substrates) to products.
Cooperativity occurs when a substrate binds to an enzyme and it enhances the catalytic activity of the enzyme.

2. Explain why photosynthesis is needed for respiration and vice versa. Provide a
specific example to support your answer.
Answer:
Explanation:
Photosynthesis uses carbon dioxide to create oxygen in the atmosphere. Oxygen is what we breathe. We do a process called cellular respiration. This means we breathe in oxygen and breathe out carbon dioxide. Plants use this carbon dioxide to do photosynthesis. It is a never-ending cycle.
For example, a bunny breathes out carbon dioxide. The plant takes carbon dioxide in and gives out oxygen. The bunny breathes in the oxygen and then again breathes out the carbon dioxide.
Which of the following is an example of a nonspecific immune response? I. White blood cells that invade the area of a cut in the skin II. An injury triggers mast cells to release histamine, causing inflammation III. Killer T-cells destroy pathogens by recognizing proteins on cell surfaces.
Nonspecific is the innate immune response that is present since birth. White blood cells and mast cells are examples of non-specific immunity.
What is a nonspecific immune response?The non-specific immune response is the immunity present in the child from his/her birth and is a generalized response that employs white blood cells and mast cells for conferring the pathogens.
It is innate immunity that protects from the invasion of pathogens and provides the first line of defence by forming barriers.
It includes the invasion of the white blood cells in the area of any cut or injury or the release of the histamine from the mast cells in an injured area for the inflammation pathway.
Therefore, the statement I about white cells and II about mast cells are examples of the non-specific immune response.

Which carbohydrate is found in the cell walls of plants.
Which agricultural practices result in methane emission?
Agricultural sources include manure pits and cow burping from “enteric fermentation,” which results from the digestive process of cattle.
What do you mean by enteric fermentation?Enteric fermentation is a digestive process by which carbohydrates are broken down by microorganisms into simple molecules for absorption into the bloodstream of an animal.
Enteric fermentation is a natural part of the digestive process in ruminant animals such as cattle, sheep, goats, and buffalo. Microbes in the digestive tract, or rumen, decompose and ferment food, producing methane as a by-product.
Enteric fermentation occurs when anaerobic microbes, called methanogens, decompose and ferment food present in the animal's digestive tract producing compounds that the animal host then absorbs.

Organisms that obtain and ingest organic molecules for their nutrition are classified as.
Answer:
Also refered to as consumers, heterotrophs are organisms that obtain their energy (nutrition) from organic compounds/materials. In other words, they are organisms that are unable to produce their own food (unlike autotrophs) and therefore have to consume/ingest organic compounds as a source of energy.
