Answer:
(Fill in the blank) When comparing DNA and structural characteristics between plant species, the similarities that appear can indicate a genetic adaptation to a particular environment, between them.
Explanation:
The evolution of the spice indicates that there were changes in the environment where these plants were able to adapt genetically, and not only that but they transmitted it in their generations, that is why many manifest the same genetic code, if this gene was inherited among them it means that the species EVOLVED.
Otherwise, those genes that generate benefits for the plants but are not transmitted in the parent plants will not be considered as an evolutionary change of the species but individual of the plant.
The genetic changes produced by modifications in the environment translate into phenotypic changes, thus generating a more suitable species with a greater chance of survival.

A nucleotide does not contain
a. a 5-carbon sugar.
b. an amino acid.
c. a nitrogen base.
d. a phosphate group.
Answer:
b.) an amino acid.
Explanation:
A nucleotide contains three things:
a 5-carbon sugar a nitrogenous basea phosphate groupSince amino acids are not on this list, the correct answer is b.
A nucleotide does not contain a amino acid.
What are nucleotides?Nucleotides are organic molecules consisting of a nucleoside and a phosphate. They serve as monomeric units of the nucleic acid polymers – deoxyribonucleic acid and ribonucleic acid, both of which are essential biomolecules within all life-forms on Earth.
Moreover, a nucleotide is the basic building block of nucleic acids (RNA and DNA). A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen-containing base. The bases used in DNA are adenine (A), cytosine (C), guanine (G) and thymine (T).
Therefore, DNA and RNA are polynucleotides, which contain a chain of nucleotides monomers with different nitrogenous bases. Nucleotides are essential for carrying out metabolic and physiological activities.

Write the definitions of the following terms.
Cell
Tissue
Organ
Organ system
Answer:
The cell (from Latin cella, meaning "small room") is the basic structural, functional, and biological unit of all known organisms. A cell is the smallest unit of life. Cells are often called the "building blocks of life". The study of cells is called cell biology, cellular biology, or cytology.
In biology, tissue is a cellular organizational level between cells and a complete organ. A tissue is an ensemble of similar cells and their extracellular matrix from the same origin that together carry out a specific function. Organs are then formed by the functional grouping together of multiple tissue
In music, the organ is a keyboard instrument of one or more pipe divisions or other means for producing tones, each played with its own keyboard, played either with the hands on a keyboard or with the feet using pedals
An organ system is a group of organs that work together as a biological system to perform one or more functions. Each organ does a particular job in the body, and is made up of distinct tissues.

Why would you expect equal numbers of guanine and cytosine in a molecule of DNA, but not necessarily in a molecule of RNA?
Answer:
DNA is double-stranded, so there must be equal numbers of C and G because they pair to each other on the complementary strands.
RNA is only single-stranded, so there can be any number of C and G. They don't pair to each other, because there's only one strand.
Equal numbers of guanine and cytosine would be expected in a molecule of DNA, but not RNA because:
DNA is double stranded with the first strand being a complimentary copy of the other. The two strands are also associated with each other by hydrogen bond.RNA is single strand.In the double strand DNA, Adenine always pair with Thymine while Guanine always pair with Cytosine. Hence the number of Adenine must be equal to that of Thymine while that of Guanine must be equal to Cytosine.
The single strandness of RNA means that it can contain an arbitrary amount of any of the bases without following a particular rule.

What happens in the condensation part of the water cycle?
Answer:
Condensation is the opposite of evaporation. It is when water molecules in the air, which are in gas form, cool and accumulate into liquid form. In the air, this is the formation of clouds and sometimes you can see condensation on your water bottle in the summer if it has a cold liquid inside. When the hotter water molecules in the air touch the bottle, it is cooled and shifts to its liquid form. When clouds accumulate enough water droplets, they become too heavy to stay in the air and fall to the earth as rain, snow, hail, etc.

What is an atom?An atom is defined as the smallest unit of matter which forms an element. Every form of matter whether solid,liquid , gas consists of atoms . Each atom has a nucleus which is composed of protons and neutrons and shells in which the electrons revolve.
The protons are positively charged and neutrons are neutral and hence the nucleus is positively charged. The electrons which revolve around the nucleus are negatively charged and hence the atom as a whole is neutral and stable due to presence of oppositely charged particles.
Atoms of the same element are similar as they have number of sub- atomic particles which on combination do not alter the chemical properties of the substances.

Analyze whether the tiger is at the same level and whether it obtains the same amount of energy in both the food chains.
Answer:
No, the tiger is not at the same level in the food chain.
Explanation:
There are two different food chains in this example: 1. Spinach --> goat --> human --> tiger 2. Spinach --> goat --> tiger.
In the first example, tiger is a tertiary consumer because it feed on secondary consumer that is human which feeds on primary consumer, while in the second example, the tiger is secondary consumer because it feeds on primary consumer that is goat which feeds on producer. In the food chain, there are different trophic levels are present such as producer, primary consumer, secondary consumer and tertiary consumer etc. Some animals act as both secondary and tertiary consumer. In these two examples, tiger act as both secondary and tertiary consumer.
Choose which way of evolution caused the FQ antibiotic resistance.
Answer:
Antibiotic resistance is an act of evolution via natural selection. The antibiotic action is an environmental pressure: those bacteria which have mutation allowing them to survive and re-produce
Explanation:
A variation in the properties of an organism over a period of time is called evolution.
Antibiotic resistance can transpire naturally or due to progression.
This type of endurance occurs so that the bacteria can persist and proliferate in the changed conditions.
Fluoroquinolones (FQ) modify the enzymes like DNA gyrase and topoisomerase IV.
The bacteria in order to survive from this antibiotic adapted mechanism so that the use of antibiotics would not hinder their reproduction mode and hence they will be able to survive.

Answer and Explanation:
Example of a food-web:
(1) Algae --> (2) Protozoas --> (3) Krill --> (4) Cephallopods --> (5) Medium sized dolphin --> (6) Large Dolphin
The trophic web is the process of energy transference through a series of organisms, in which every organism feeds on the preceding one and becomes food for the next one.
1) The first link is an autotroph organism or producer, such as a vegetable, that can synthesize organic matter from inorganic matter. In this example, the autotroph organisms are algae, that make use of sunlight and inorganic matter.
The next links are the consumers:
2) Herbivores are primary consumers and feed on producers. In this example, herbivore organisms are protozoan.
3) Krills are the secondary consumers and feed on protozoans.
4) Some species of cephalopods feed on krill, among other species.
5) Specialized Cetaceans such as the Risso´s dolphin, feed especially on cephalopods, as they lack upper teeth and they only have a few teeth in their jaws.
