recently, state forests and parks like yellowstone national park which contain varieties of flowering trees and shrubs, have started to erect signs that state, take nothing but pictures, leave nothing but footprints. which argument best supports why these signs are being placed in state forests and parks?
The argument that best supports why the signs are placed in the parks is that humans have the capacity to cause damages to the stability of ecosystems through their actions.
By removing tissues of plants or even entire plants, the stability of the entire park can be disrupted depending on the role such a plant plays in the ecosystem. Some species of organisms in the ecosystem play key roles and their removal or damages may cause significant disruption to the entire ecosystem.
Also, by leaving things that can be harmful to the plant species in parks, immeasurable damages can be done to the entire ecosystem.

Explanation:
1.There are some characteristics that are inherited from your parents, shape of blood cells is one of them. In sexual reproduction, offspring are formed when sperm of male combine with egg of female organism.Therefore, some characteristics comes from male organism and some from female organism. In sexual reproduction, diploid organism is formed because half of genes comes from male and half comes from female.
2.Heredity, also called inheritance or biological inheritance, is the passing on of traits from parents to their offspring; either through asexual reproduction or sexual reproduction, the offspring cells or organisms acquire the genetic information of their parents
3.A monk, Mendel discovered the basic principles of heredity through experiments in his monastery's garden. His experiments showed that the inheritance of certain traits in pea plants follows particular patterns, subsequently becoming the foundation of modern genetics and leading to the study of heredit
4.Mendel made sure to study 30,00 pea plants when he presented his data to the community. Another example is when Mendel painstakingly removed all of the immature anthers from the plant’s flowers before the cross.Mendel used seven pea plant traits in his experiments which include flower color (purple or white), flower position (axil or terminal), stem length (long or short), seed shape (round or wrinkled), seed color (yellow or green), pod shape (inflated or constricted), and pod color (yellow or green).
5.A pea plant could have a copy of the height gene that coded for "tall" and a copy of the same gene that coded for "short." But the tall allele is "dominant," meaning that a tall-short allele combination would result in a tall plant

what is the difference in solubility of triglyceride and the products of their hydrolysis
Answer: Triacylglycerols are the major constituents of oils and fats of both plant and animal origin.
Explanation:
Hope this helps.
The products of hydrolysis of triglycerides are fatty acids and glycerol. While fatty acids, like triglycerides, are insoluble in water, glycerol is soluble in water.
Why are triglycerides insoluble?Triglycerides are esters of fatty acids and alcohol, mostly glycerol. The fatty acid chains are inked to the glycerol molecules with the help of covalent bonds.
This means that the triglyceride molecule is uncharged and will therefore remain insoluble in water but soluble in organic solvents.
Also, products of hydrolysis of triglycerides are fatter acids and glycerol. While fatty acids will remain insoluble in water, glycerol is soluble in water.
Glycerol is alcohol with 3 hydroxyl groups, this is why it is also called a polyol. They are able to hydrogen bonds with the nearby water molecules.
Therefore, triglycerides and fatty acids are insoluble and glycerol is soluble in water.

what essential chemicals do the light dependent reactions obtain from the light independent reactions
Explanation:
Light Reactions: Light-dependent reactions harness energy from the sun to produce chemical bonds, ATP, and NADPH. These energy-carrying molecules are made in the stroma where the Calvin cycle takes place.
The energy storage molecule ATP and the reduced electron carrier NADPH are produced by the light-dependent processes using light energy, which is required for the subsequent stage of photosynthesis.
What are the products of the light-independent reactions check all that apply?
In order to make ATP and NADPH, the light-dependent processes of photosynthesis must first collect energy from the sun.Then, these two molecules that store energy are employed in the light-independent reactions. Two different types of energy-carrier molecules, ATP and NADPH, store the solar energy in the light-dependent reactions.These molecules' stored energy is contained in the bond that binds one atom to the molecule.It is a phosphate atom for ATP and a hydrogen atom for NADPH. The cell has the material it needs to create carbohydrate molecules once the energy from the sun is processed and packed into ATP and NADPH.Carbon atoms will form the backbone of the carbohydrate molecules created. The protein ferredoxin receives electrons from the pigment P700 in its reaction center. Ferredoxin can then donate the electrons to either the electron transport chain to produce more ATP or to the electron carrier NADP+ to make NADPH. The pigment chlorophyll in the thylakoid membranes of the chloroplast is able to absorb solar energy during these reactions.The second stage of photosynthesis uses the molecules ATP and NADPH, which are temporarily transferred the energy to. Chlorophyll absorbs solar energy during the light-dependent reactions and transforms it into chemical energy that is then stored.The chemical energy obtained during the light-dependent reactions powers the construction of sugar molecules from carbon dioxide in the light-independent reactions. Plants require three elements for photosynthesis: carbon dioxide, water, and sunshine. The reactions that depend on light include those that use it to split water, create ATP, and NADPH.The processes that use ATP and NADPH to repair carbon dioxide in order to produce the three-carbon sugar glyceraldehyde 3 phosphate are known as light independent reactions. NADP, ADP, and water molecule reactants are used in the light reaction.After the light processes are finished, the molecules ATP, NADPH, and oxygen are produced, the last of which is already regarded as a byproduct of photosynthesis.To learn more about independent reactions refer
