List the type of molecules that generally act as intermediate or relay molecules.
Answer:
proteins
Explanation:
Many signal transduction pathways amplify the initial signal, so that one molecule of ligand can lead to the activation of many molecules of a downstream target. The molecules that relay a signal are often proteins. However, non-protein molecules like ions and phospholipids can also play important roles

Biology can be troubling, and only comes natural to certain people. It is ok not to understand, just follow along in the textbook if you have one, and listen to the teacher. My teacher talks a little complicated but once in a while you will pick up something interesting. If you really need additional help, there are some Biointeractive videos around the internet, that really helped me to understand what I needed to know.
Explanation:
The definition of Biology in real terms is basically the study of living organisms, that covers a wide variety of subjects related to the organism being studied, such as the Mitosis reproduction, genetics, and how life began on Earth. I hope this helps.
A segment of DNA that codes for RNA, and can vary in length from a few hundred to as many as two million base pairs in length best defines a(n)
We can confirm that a segment of DNA that codes for RNA and can vary in length from a few hundred to as many as two million base pairs in length best defines a gene.
What is a gene?To expand on the definition given, we can say that a gene is, as mentioned, a series of base pairs known as nucleotides that will code for RNA. The RNA in question is messenger RNA that will later become a protein. Through this process, genes code for every aspect of an organism and will determine its morphology and all other biological aspects.
Therefore, we can confirm that a segment of DNA that codes for RNA and can vary in length from a few hundred to as many as two million base pairs in length best defines a gene.

Anticodons help the tRNA retrieve the correct nucleic acid.
Anticodons help the tRNA retrieve the correct amino acid.
Anticodons tell the tRNA when to begin retrieving amino acids.
Answer:
Anticodons help the tRNA retrieve the correct amino acid.

Explain how ecosystem services link rural lands with urban lands?.
Ecosystem services link rural lands with urban lands because people living in urban lands need resources that only come from rural areas such as crops, clean drinking water, fertile soil, and trees. ... Humans use forest land for harvesting wood, wildlife, fish, nuts, and other resources.
The advantages that come from ecosystems to people are called ecosystem services. Clean air and water, food production, and recreational activities are just a few of these advantages.
What is ecosystem?An ecosystem is a region where a bubble of life is created by plants, animals, and other organisms interacting with the weather, environment, and other factors.
First, rural lands offer crucial ecosystem services that are necessary for metropolitan regions to function.
Second, urban regions can provide rural areas with crucial ecosystem services.
Urban areas, for instance, might offer markets for agricultural products as well as financial and technological support for sustainable agricultural methods.
Third, the viability of both urban and rural communities depends on their connections. The movements of materials, energy, and information that unite urban and rural areas create a connection between them.
Finally, ecosystem services act as a vital link between rural and urban areas.
Thus, this way, ecosystem services link rural lands with urban lands.

How is fungi different from other kingdoms?
Answer:
➢ A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. ... Fungi do not photosynthesize. Growth is their means of mobility, except for spores (a few of which are flagellated), which may travel through the air or water.

What is the relationship between systematics and taxonomy?.
The primary distinction between taxonomy and systematics is that taxonomy is concerned with the classification and naming of creatures, whereas systematics is concerned with the determination of organisms' evolutionary relationships. This means that systematics determines whether or not different organisms share a common ancestor.
One theory of aging that makes apparent commonsense postulates that organisms have only so much energy to expend in a lifetime. Therefore, the basic idea is that the rate of a creature's metabolism is
Given what we know, we can confirm that the basic idea resulting from these studies is that a creature's metabolism is related to its lifespan.
How is metabolism related to lifespan?From the studies done and the comparison of the lifespan of certain species in relation to their metabolic rates, scientists have noticed that metabolism and lifespan are inversely proportional. The slower the metabolism of an organism, the longer that organism can live.
Therefore, we can confirm that the basic idea is that a creature's metabolism is inversely proportional to its lifespan, meaning that the faster the metabolism, the shorter the lifespan of the creature in question.

The steepest slope on this hill can be found on the side that is facing which direction?
Answer: the answer is northeast
Explanation:
Answer:
Northeast
Explanation:
To find the steepest part of a topographic map, simply look at the contour lines and if they are close together, they are steep, but if they are distanced fairly they are at a gentler slope range. Also if they are very far apart the land would be flat, which is both good for farming and housing. Since there was no topograpic model of a land structure given in this answer, I chose to go with assumptions of most land structures such as mountains or volcanoes which have commonly had the steepest part be in the Northeast, as this fact can be support by geological evidence and the movement of the plate tetonic and the convergent boundaries that border most of the mountains on the planet earth.

What happens in a decomposition reaction? O A. Two or more substances combine to form one substance. B. Two ions trade places. O C. Larger compounds break down into two or more smaller compounds O D. The charges of the atoms change.
Answer:
C. Larger compounds break down into two or more smaller compounds.
Explanation:
During a decomposition reaction, the bonds between the atoms break down in the starting substance. The atoms then rearrange to form new bonds, resulting in new substances with properties different from the starting material.
In a chemical compound, would you expect an oxide ion to be joined with one atom of calcium or
one atom of potassium? Why?
Answer:
An oxide ion, an oxygen ion with a -2 charge, should be joined with 1 atom of calcium in a chemical combination. Ca+2 O-2 would create CaO, just as it would in the formation of a compound, as we can see from the chemical formula.For more info:
