Mycelium is the entire interwoven mass of one multicellular fungal organism. It is composed of thin, thread-like strands of cells called hyphae.
Mycelium is the vegetative part of a fungus, and is generally hidden in the soil or inside of its host. Mycelium is a vital part of the fungal life cycle, as it is responsible for absorption of nutrients and water, reproduction, and dispersal of spores.
It is also involved in the formation of beneficial relationships with other organisms, such as the mycorrhizal fungi which help plants to uptake nutrients from the soil.
Mycelium plays an important role in the health of ecosystems, as it breaks down organic matter, recycles nutrients, and forms symbiotic relationships with other organisms. Without mycelium, the world would look very different.

Why does temperature change always move from regions of hot to regions of cold?
When two bodies with different temperatures come into thermal contact, they exchange heat energy until they attain thermal equilibrium, at which point the cold body warms up and the hot body cools down.
What is thermal conduction?The process by which heat is transmitted from an object's hotter end to its colder end is known as conduction.
The term "thermal conductivity" refers to an object's capacity to transfer heat, and it is represented by the letter k. Heat naturally moves in the direction of a temperature gradient.
Thermal conduction is the term used to describe the flow of energy (heat) caused by temperature variations between nearby body parts.
The kinetic energy of the atoms in hot bodies is higher than that of the atoms in cold bodies.
The higher kinetic energy atoms attempt to move and collide with the lower kinetic energy atoms in order to preserve thermal equilibrium. As a result, heat can be transferred from a hot body to a cold body.
Thus, temperature change always move from regions of hot to regions of cold.

¿Qué se puede agregar a un átomo para hacer que un electrón sin valencia en el átomo se convierta temporalmente en un electrón de valencia? energía masa neutrones electrones
Energía.
Explicación:
Generalmente, los electrones giran continuamente en las capas de los átomos. Si estos electrones se encuentran en las capas más externas de un átomo, se denominan electrones de valencia.
Son necesarios para las reacciones químicas de un átomo en particular con otro, a través de sus pérdidas o compartidas.
En los átomos sin valencia, sus capas más externas no tienen electrones en sus capas más externas, tales átomos son estables.
Sin embargo, si se suministra cierta cantidad de energía a dicho átomo, el electrón gana energía y, por lo tanto, se excita.
Por lo tanto, se mueven de niveles de energía más bajos a niveles de energía más altos, y hacen que el átomo sin valencia se convierta en valencia temporalmente, a medida que se mueven hacia la capa más externa.
Answer:
Energy.
Explanation:
Generally, electrons revolves continuously in the shells of atoms.if these electrons are located in the outer most shells of an atom,they are refereed to as the Valence electrons.
They are needed for chemical reactions of a particular atom with another,through their loses or sharing.
In Non -valence atoms their outermost shells do not have electrons at their outermost shells,such atoms are stable.
However, if certain quantity of energy is supplied to such atom, the electron gains energy and therefore becomes excited.
They therefore move from lower energy levels to higher energy levels,and makes the non- valence atom becomes valence temporarily, as they move into the outermost shell.

A) 956. 5 in2
B) 1,104. 5 in2
C) 1,365. 5 in2
D) 1795. 5 in2
Given that Eric is hanging a rectangle mirror that has a diagonal of 47 inches with an angle of depression of 60°. We are supposed to calculate the area of the mirror.
Let's draw the diagram for this question:From the diagram we can see that the given rectangle is being divided into two right \(triangles\). And the given angle is the angle of depression which can be written as the angle of elevation of the person who is standing on the ground. The diagonal of the rectangle can be calculated as follows: If we consider a right triangle, one leg of the triangle is the length of the rectangle and the other leg is the width of the rectangle. And the diagonal of the rectangle is the hypotenuse of the right triangle using Pythagoras theorem we get:
Width2 + Length2 = Diagonal2Length2 = Diagonal2 - Width2Length = √(47² - 36²)Length = √(2209 - 1296)Length = √913Length = 30.19 inches Let's calculate the height of the rectangle: If we consider the right triangle with the angle of 60 degrees, the opposite side to the angle of 60 degrees is the height of the rectangle. And we have hypotenuse and we can use trigonometry formula to find the height.Height = Hypotenuse * sin(60)Height = 47 * sin(60)Height = 47 * 0.866Height = 40.75 inchesNow, we can calculate the area of the rectangle using the following formula: Area = length * widthArea = 30.19 * 40.75Area = 1231.2425 inches^2

Lipid oxidation is the main reason for:
O High cholesterol levels
O Heart disease
O The formation of triglycerides
O Food spoilage
O None of the above
Answer: Food spoilage
Explanation:
Lipid oxidation cause food spoilage because lipid oxidation is the oxidative degradation of lipids that occur when free hydroxyl attract electron from the fatty acids. These make the lipid radical to be unstable and the fatty acids reacts with oxygen to form fatty acid peroxyl radical which is the major causes of food deterioration. Oxidation occurs by defferent molecular mechanisms such as production of reactive oxygen precursors and free radicals. Continuous occurrence of this can result in lung damage.
If you gave a person with primary hypothyroidism (iodine deficiency) an injection of TSH would T3 and T4 levels increase? Why or why not?
no. Due to iodine deficiency, even if you stimulated the thyroid gland with TSH, you will not identify an increase in T3 and T4 synthesis in these individuals.
Thyroxine (T4) and triiodothyronine, two thyroid hormones, are produced by the thyroid gland from iodine, which is present in a variety of diets (T3). In the body, iodine can only be absorbed by thyroid cells. To produce T3 and T4, these cells mix the elements iodine and tyrosine. Iodine is a key necessary mineral without which the thyroid cannot produce enough amounts of T4 and T3. The pituitary, a gland located directly below the brain, is responsible for controlling thyroid activity. Thyroid-stimulating hormone (TSH) is created by the pituitary, and it encourages the thyroid to make T3 and T4.

why are owls considered keystone predator
Explanation:
Keystone species are animals that help manage other animal species by controlling population numbers and biodiversity within an ecosystem. The impacts of keystone species are usually greater than their numbers.
owls can be a great benefit to places where rodent populations are high. Dense urban areas often suffer from an abundance of rats and mice spreading disease, and rural agricultural communities have their crops consumed and soil eroded from burrowing voles and field mice. Without owls, and other top predators, rodent populations could explode and exacerbate the effects they produce.
Answer:
the owl is a keystone species, as many other birds. and it gives them the nutrients they need when they eat the bird and it mangeges the population of the other species:)

is the entire zygote involved in early cleavage? what evidence to you have to support your answer?
Yes, the entire zygote is involved in early cleavage.
Evidence to support this statement includes the following:
Definition of cleavage: Cleavage is the process of cell division that occurs after fertilization, where the zygote divides into multiple cells called blastomeres. Since cleavage involves the division of the zygote, the entire zygote is involved in this process.Purpose of cleavage: The primary purpose of cleavage is to increase the number of cells without increasing the overall size of the embryo. This is achieved by the entire zygote dividing into smaller cells.Uniformity of blastomeres: During early cleavage, the blastomeres are generally similar in size and appearance. This uniformity suggests that the entire zygote is involved in the cleavage process.Holoblastic cleavage: In many animals, including mammals, the zygote undergoes holoblastic cleavage.

Answer:
D
Explanation:
Each reaction starts at 0J (i.e. no energy). So, you can eliminate C. and B. simply by comparing the start point (A) to those end points.
Product B does not contain more energy than reactant A because the line falls below the axis (falls below zero). (You can apply this same logic for question C)
A. is incorrect because all the reactions appear to be occurring on the same time scale.
D. is the best answer because activation energy is best identifiable difference between these three reactions. The 'hump' in the graph represents the activation energy. The higher the hump, the higher the energy.
