2. What are three characteristics of carbon that contribute to the diversity of organic compounds?
Catenation:
The property of self linkage among identical atoms to form long chain compounds is known as catenation. Carbon exhibits maximum catenation, when compared to elements like sulphur and silicon, due to strong carbon-carbon bonds and tetra valency. Due to this catenation, carbon atoms can form various types of straight chains, branched chains and ring structures.
Formation of multiple bonds:
Carbon atoms are capable of forming multiple bonds with other carbon atoms.
Hydrocarbons:
All the carbon compounds which contain just carbon and hydrogen are called hydrocarbons.
isomerism arises from the difference in the structure of carbon chain which forms the nucleus of the molecule. It is, therefore, named as chain, nuclear isomerism or Skeletal isomerism. For example, there are known three pentanes which have the same molecular formula.
Freshwater leeches attach to fish and suck blood from the fish for extended periods of time. This results in sores on the fish that often become infected.
what is This relationship is best described as i will mark brainliest if less than 10 min im in junior high
.
Answer:
Parasitism
Explanation:
This type of relationship involves one organism living with, on, or inside another organism and harming it. This relationship involves:
Host - the one being harmed in parasitism in this case the fish.
Parasite - the organism (the one doing the harm) that benefits in parasitsm in this case the leech.
6. Photosynthesis can combat global warming. Explain with reasons.
Plants take carbon dioxide (CO2) out of the atmosphere to do photosynthesis, and thus help reduce the greenhouse gases warming the planet.
Explanation:
Plants, through photosynthesis, and soils sequester roughly a third of carbon dioxide emissions released into the atmosphere each decade from the burning of fossil fuels. During photosynthesis, plants open tiny pores on their leaf surfaces to suck carbon dioxide from the air and produce their own food.
Distinguish how an animal welfare activist would most likely feel about the animals’ housing and training in the following scenario.
A traveling circus uses a number of animals in its act, including a tiger and a small herd of elephants. When traveling, the tiger gets its own car and attendants who feed it regularly. The elephants are dispersed among three cars and each has a number of attendants who feed and clean up the elephants’ waste. To train the animals, the circus hires animal trainers who use whips to teach the animals how to behave in the ring.
Answer:
using whips on animals is not a desirable activity, as well as circus' being notorious for the mistreatment of animals, I think anybody who had these animals welfare in mind would disapprove of this scenario

What is a mutation? a a misinterpretation of the daughter strand b a break down of the mRNA structures in the cell c any change in the nucleotide sequence d a function of the ribosome
Mutation can be defined as any change in the nucleotide sequence. That is option C.
What is nucleotide sequence?Nucleotide sequence can be defined as the sequence of bases that are arranged in a particular form which contains instructions for the synthesis of proteins in a cell.
When there is a change in this sequence, mutation is said to have occurred.
Therefore, Mutation can be defined as any change in the nucleotide sequence.

total saturation of protein transporters for a given solute in the renal tubules would result in __________.
Answer:
absence of that solute from the urine
Explanation:
A protein transporter is involved in the transportation of the ions and the molecules. If a membrane protein transporter gets totally saturated in the renal tubules, then that solute will appear in the urine.
What are transport proteins?Transport proteins are the transporters that move the molecules, ions, and macromolecules in and out of the cell. They carry the molecules and substances across the biological membrane and allow their diffusion.
If a transport protein saturates a solute totally in the renal tubules, then that solute will get secreted in the urine as they are easily soluble in the water and the fluid of the excretion system.
Therefore, the solute will get excreted in the urine.

Why must cytosine bind to guanine, while thymine bonds to adenine?
a
These are Chargaff's rules.
b
Like bonds with like.
c
Two-ring molecules (adenine and guanine) must bind with one-ring molecules (thymine and guanine) to keep the distance between DNA chains consistent.
d
This will not happen, as it violates Chargaff's rules.
These are Chargaff's rules that is why cytosine bind to guanine, while thymine bonds to adenine. Thus, the correct option is A.
What is Chargaff's rule?According to the rule, in DNA there is always equality in quantity between the bases A and T and between the bases G and C. (A is adenine, T is thymine, G is guanine, and C is cytosine).
According to Chargaff's rule, Concentration of adenine = concentration of thymine. therefore if [A]=40% then the [T] will also be 40%.

The picture represents the atypical mole or also known as dysplastic nevi. Such types of moles are looking unusual and have irregular features under the microscope.
What is a Human scalp?A human scalp may be defined as the fraction of the envelope of the human head usually covered with hair in both sexes. It is the region that is composed of soft tissue layers that cover the cranium.
The dysplastic nevi are although benign in nature but significantly have a potent threat to melanoma which is a dangerous form of skin cancer.
Such types of moles are painful, itching, crusting, and swelling with the duration of time. They are required to be checked immediately by a trusted dermatologist.
Therefore, the picture represents the atypical mole or also known as dysplastic nevi.

an apple falls out of a tree if gravity is the action force that is acting on it what would the reaction force be?
A) momentum
B) air resistance
C) thermal velocity
D) anti-gravity
Answer:
B) Air Resistance
Explanation:
A reaction force is the opposite of an action force, so what is opposing gravity? Momentum certainly isn't in this instance of the apple falling. Thermal velocity isn't, and anti gravity is a hypothetical phenomenon.
Answer:
B) air resistance
Explanation:
When an falls out of a tree, gravity is acting downwards, and the reaction force which counters it is air resistance.

The net primary productivity (NPP) and the gross primary productivity (GPP) are related such that: NPP = GPP - Respiration
What is NPP?NPP refers to the net primary productivity of ecosystems. It is the amount of sugar made from photosynthesis when the amount of sugar burned during respiration has been deducted.
The total amount of sugar made during photosynthesis is the Gross Primary Productivity (GPP). This amount does not include the amount of sugar burned by respiration.
Thus, the equation relating the 3 variables would be:
