13. Give one use for ethyne.
Answer:
Ethyne is useful for artificial ripening and preservation of fruits. It is useful in acetylene lamps to generate light. Ethyne is used to prepare various organic compounds. It is also useful to manufacture important organic compounds like acetic acid, acetaldehyde, ethyl alcohol and polymers like PVC, etc.
Explanation:
Since ethyne burns with a very hot flame, one of its most notable applications is in oxyacetylene gas welding and oxyacetylene gas cutting. When ethyne is subjected to combustion with oxygen, the flame created is known to have a temperature of roughly 3600 Kelvin.

Four o’clock flowers can be red (RR), white (rr), or pink (Rr). If a pink flower and red flower are crossed, what will be the phenotypic ratio?
100% pink
50% red, 50% pink
100% Rr
50% RR, 50% Rr
Answer:
See below ~
Explanation:
If red and pink flowers are crossed, then there will be :
50% red, 50% pink 50% RR, 50% RrSo if both are crossed
The total combination is 100% But as there are 2 so it should be 100/2=50% for Red and pinkSo
the ratio is
50% RR and 50% rrWhat are the best ways to control invasive species including plants, pests and pathogens?
Answer:
Prevention is the most cost-effective and safest method of controlling invasive species. Detecting invasive species early and responding quickly is far more effective than trying to control a vast infestation. Invasive species may be subject to control and management efforts if eradication is not achievable.

Why does social science intersect with marine science?
A. Many poems and novels are written about the ocean.
B. Human behavior causes a lot of issues with the ocean.
C. Social science is another important branch of the sciences.
D. These are very different disciplines that have little connection.
Answer:
it's either b or d I think
Social science intersects with marine science because human behavior causes a lot of issues with the ocean.The correct option is B.
The ocean is a body of salt water that covers approximately 70.8% of the Earth and contains 97% of Earth's water, making Earth an ocean world. The term ocean also refers to any of the large bodies of water into which the world ocean is conventionally divided.Distinct names are used to identify five different areas of the ocean: Pacific , Atlantic, Indian, Southern, and Arctic.
Seawater covers approximately 361,000,000 km² of the planet. The ocean is the primary component of the Earth's hydrosphere, and thus essential to life on Earth. The ocean influences climate and weather patterns, the carbon cycle, and the water cycle by acting as a huge heat reservoir.Pollution of water by human activities makes the marine science intersect with social science.
Thus, option B is correct.

When making bread,you add yeastand sugar, buti does not taste steet, why?
Answer:
You don't have enough sweet ingredients in the bread. The other ingredients outbalance the sweet ingredients
Explanation:
Answer:
Yeast is a fungus, and eats sugar for energy. When this occurs, carbon dioxide and fermentation occurs, in which the carbon dioxide is trapped within the bread, allowing for it to rise. If there is little to no sugar left after the bread is completed, then the bread will not taste sweet.

Termites share an endosymbiotic relationship with the protozoan that live in their gut. Which statements are true of this relationship? Check all that apply.
A: The termite benefits from the relationship by receiving food from the protozoan.
B: The protozoan benefits from the relationship by receiving shelter and food from the termite.
C: Protozoan only exist inside termites.
Answer:
Explanation:
The true statements are:
-The termite benefits from the relationship by receiving food from the protozoan
-The protozoan benefits from the relationship by receiving shelter and food from the termite
The second statement is obvious. The protozoan lives in the termite, eating what the termite eats and enjoying the shelter the termite provides. The first statement is also true, but poorly worded. the termite does not actually receive food from the protozoan. The protozoan only helps to digest the food that the termite has already consumed.

How do we calculate chnage in free energy?Change in gibbs free energy of any reaction will be calculated by uisng the below equation as:
ΔG = ΔH - TΔS, where
ΔH = change in enthalpy
T = temperature of reaction
ΔS = chnage in entropy
By putting all given values we can calculate the gibbs free energy of the reaction, and negative sign of energy shows the spontaneity of the reaction.
Hence by using the enthalpy, entropy and temperature we can calculate the free energy change.

Free energy refers to the energy in a system that is free to do work i.e. the internal energy minus any energy that is unavailable to perform work.
Why is use of free energy?Free energy is used to determine how systems change and how much work they can produce. It is expressed in two forms: the Helmholtz free energy F, sometimes called the work function, and the Gibbs free energy G.
The free energy change of a reaction can be calculated using the following expression: ΔG∘=ΔH∘−TΔS∘. where ΔG=free energy change.

After a forest fire, which type of organisms will begin secondary succession?.
Answer:
herbaceous plants
After a fire, species start to recolonize an area, beginning the secondary succession process. The first species to colonize are usually fast growing herbaceous plants, such as conifers or ferns, which require high levels of light.
Pioneering or early successional species are the kind of organisms that usually start secondary succession after a forest fire.
Thus, these creatures include grasses, herbaceous plants, and tiny shrubs that are small and have a rapid rate of growth. They have evolved to colonize and prosper in open, uncontrolled environments.
Pioneering species have developed systems that enable them to quickly germinate, develop, and reproduce while using the sunshine and nutrients that are accessible.
They support soil stability, moisture retention, and the development of additional plant species through improving environmental conditions. These early-successional species provide the way for the ultimate re-emergence of more mature trees and a complex forest ecosystem when secondary succession develops.
