6 . binomial nomenclature The largest taxonomic category
7 . taxon A taxonomic category containing a group of similar families
8 . division In classification (other than plant), a grouping of similar classes
9 . biosphere The categories used in classifying plants and animals
Answer:
Please find the correctly matched terms with their definition below:
Explanation:
1. Binomial nomenclature: As the name implies i.e. Binomial meaning"two", binomial nomenclature is the two-name system of naming living things used in classification.
2. Biosphere: Biosphere refers to all life on Earth including plants, animals, microbes etc.
3. Class: Class is one of the seven levels of classification, which is a taxonomic category containing a group of similar orders.
4. Phylum: Phylum is also a level of classification used majorly for classifying plants. In plant classification, It is a group of similar classes.
5. International Code of Nomenclature: Abbreviated as IUCN, it is an elaborate set of rules for naming organisms in taxonomy.
6. Kingdom: Kingdom is the least specific taxon. Kingdom represents the largest taxonomic category containing most organisms.
7. Order: Another level of classification that describes a taxonomic category containing a group of similar families.
8. Division: Division is a taxon used instead of phylum when a plant is not involved. In classification (other than plant), phylum is a grouping of similar classes.
9. Taxon: Taxon refers to the categories used in classifying plants and animals.
Answer:
1. Species refers to the biological term that signifies the smallest unit or the basic unit of classification. Thus, 1 can be correctly matched with species. 2. The Arthropods refers to the species that exhibits an exoskeleton, paired jointed legs and segmented body. Thus, 2 can be correctly matched with Arthropods and animal characteristics. 3. The largest phylum of animals is Arthropods. Thus, 3 can also be correctly matched with Arthropod. 4. The Tracheophyta signifies towards the green plants that exhibit conductive tissues for mediating nutrients and water through them. Thus, 4 can be correctly matched with Tracheophyta. 5. Taxonomy refers to the branch of science that deals with the classification of species. Thus, 5 can be correctly matched with taxonomy. 6. The order is considered as a group of families. Thus, 6 can be correctly matched with order. 7. Tracheophyta is considered as the largest division of plants. Thus, 7 can be correctly matched with Tracheophyta.
Explanation:
Dr. Mrs. Brown has Rh+ blood, but her father is Rh-. What must her full blood type genotype be?
Answer:
Her full blood type genotype is Dd.
Explanation:
Rh (Rhesus) factor is a type of protein found on the outside of red blood cells. It is genetically inherited. An individual that has this protein is Rh-positive, and the one that doesn't is Rh-negative. The Rh-positive gene is dominant, while the Rh-negative gene is recessive. This means that a person must inherit at least one dominant (D) allele from their parents in order to be Rh-positive.
If Dr. Mrs. Brown is Rh-positive, and her father is Rh-negative, her mother must be Rh-positive (DD or Dd), as well. Her father has two recessive alleles (dd), which means that Dr. Mrs. Brown must have one recessive allele. Since she is Rh-positive, she must have one dominant allele. This makes her genotype Dd.

Answer:
DNA
Explanation:
Common knowledge
Imagine you are studying a population of finches on one of the Galápagos Islands. You have been recording many of the birds' physical traits, including the length of both wings. You observe that for 80% of individuals measured, the length of the left wing is not significantly different from the length of the right wing (in other words, they are symmetrical). But for about 20% of birds measured, the wing lengths are asymmetrical. This distribution is true from generation to generation. Suddenly, a rare 5-day windstorm takes over the island. After the storm, you spend the next several days netting each bird on the island that survived the storm. You discover that 85% of the birds with symmetrical wings survived the storm, whereas only 5% of the birds with asymmetrical wings did.
a. Propose a hypothesis to explain this observation.
b. If such storms become increasingly common due to changes in climate, how might you expect the population to change over time with respect to wing symmetry? The distribution of symmetrical to asymmetrical will change so that close to 100% of birds will have symmetrical wingspans.
Answer:
a) The change in the character of an organism relies upon the ability of the adaption on the base of the external change or the environment change, "An organism that is not able to adapt accordingly would not survive and eliminated from the population."
b) In the given case, Symmetric wings are far more suitable for the survivorship as it provides better flight than the organism with asymmetric wings, it is also given that there is 20% of the population have asymmetric wings.
After the storm which is selection pressure, there is the elimination of the entire bird population with asymmetrical wings from the ecosystem so the final frequency would be 100% of the entire population with symmetrical wings.
Natural selection benefits the phenotype that increases the fitness. a) Symetrical wings increase the fitness of finches because they are better to face selective pressures. b) natural selection will favor symmetrical wings.
-------------------------------------
a) Hypothesis:
Symmetrical wings increase the fitness of finches because these type of wings are better to face selective pressures like severe windstorms.
b) If such storms become increasingly common with time, natural selection will favor symmetrical wings by increasing its frequency in the population, while animals with asymetrical wings will decrease to near cero.
Natural selection is an evolutive force that selects beneficial alleles and increases their frequency in the population. It is the result of the phenotype-environment interaction which determines gene destiny in space and time. Natural selection results in adaptation, which means the increase of the aptitude phenotype. Aptitude is the contribution of each genotype to the next generation. Aptitude (or fitness) is reflected by the phenotype that results in the survival, fertility, and capability of having a mate. Adaptations can be correlated to environmental factors or selective pressures applied by other organisms or habitats. The selective agent is the environmental trait that determines the differential survival of the phenotypic classes. The environment influences the probability that each genotype passes its gametes to the next generation.So in this example,
⇒ The strong storms are acting as selective pressures.
⇒ This selective pressure is modeling the phenotype of finches.
⇒ Natural selection favors the phenotype that performs better when facing storms.
⇒ Symmetrical wings are the phenotype that better suits and increases the animal's fitness.
⇒ Hence, natural selection favors this phenotype over asymmetrical wings.

A. The diets of dogs and wolves are more similar that the diets of dogs and foxes.
B. The lifespans of dogs and wolves are more similar than the lifespans of dogs and foxes.
C. The genetic sequences (DNA) of dogs and wolves are more similar than the genetic sequences of dogs and foxes.
D. The body sizes of dogs and wolves are more similar than the body sizes of dogs and foxes.
The observation that provides the best evidence that dogs are more related to wolves than to foxes is the DNA sequence of dogs and wolves being more similar than that of dogs and foxes.
The DNA is a molecule that stores the genetic information of organisms. Thus, closely related organisms have similar information on their DNA, usually indicated by similar nucleotide sequences.
Therefore, if dogs and wolves are more closely related in ancestry than dogs and foxes, the DNA sequence of dogs and wolves will be more similar than the DNA sequence of dogs and foxes.

In tomatoes, red fruit color is dominant, R, to yellow fruit color, r. A farmer has tomatoes that produce either red or yellow tomatoes. He has signed a contract with a large seed company to provide pure, RR, and pure yellow seeds, rr. They do not want any hybrids. How could the farmer tell if his tomatoes are pure or hybrid?
Answer:
He should perform a "testcross" by crossing the tomatoes in question with yellow-fruited plants.
If they are pure, all offpsring will be Red: RR x rr = all Rr
If they are hybrids (heterozygous), half the offspring will have yellow fruits: Rr x rr = 1:1 (red to yellow)

Which is an effect of lower levels of solar radiation striking Earth?
Answer:
B) decreased rates of photosynthesis
Explanation:
Plants, phytoplankton, algae, and other microorganisms photosynthesize using energy in the form of solar radiation. Photosynthesis is a chemical process that's integral to these organisms, which are called producers.
They combine light energy from solar water and carbon dioxide, in a complex process that produces chemical energy in the form of glucose.
[tex]6CO_{2} + 6H_{2} O + light ---> C_{6}H_{12}O_{6}[/tex][tex]+6O_{2}[/tex]
Photosynthesis is a rate-limited reaction; it depends on various factors including carbon dioxide availability and light intensity. When light is limited, the rate of photosynthesis decreases due to its slowing effect on the light-dependent reaction in photosynthesis, occurring in the chlorophyll.

What is the role of an enzyme in a reaction with the reaction ? would the reaction happen without an enzyme?
Answer:
Enzymes are not used up in a chemical reaction. Usually, the enzyme will “reset” and be ready to use in another reaction. This is due to the fact that enzymes are proteins, and their shape is what they use in a chemical reaction.
Explanation:
Enzymes serve a similar purpose for chemical reactions in an organism's body, which is to lower the amount of "activation energy" needed for a particular chemical reaction to occur. Without enzymes, many chemical reactions would occur at a much slower rate because the amount of activation energy required would be far greater.

Anatomy: If an agonist produces flexion, the primary action of the antagonist will be...
A. Extension
B. Abduction
C. Pronation
D. Adduction
In need of help!!!!
Answer:
If an agonist muscle produces a flexion, the primary action of the antagonist muscle will be extension.
Explanation:
Muscles are the organs of the musculoskeletal system that, through their contraction and relaxation, allow body movements.
Due to the location of each muscle in relation to the bone and joint, they can perform diverse movements, there being the so-called agonist and antagonist muscles for each movement.
If an agonist muscle makes a movement, the antagonist muscle or muscles will make the opposite movement, so the extension corresponds to the antagonistic action of the flexion.
The other options are not correct because:
B y D. Abduction and adduction are antagonistic movements, not related to flexion.
C. The antagonistic movement of pronation is supination.

C
Explanation:
The exerpt states that movements in the Earth's crust (unbalance) causes Earthquakes. When it's balanced, there is no plate movement.
Answer: c
Explanation: if there is no plate movement that means that there is a balanced force there is nothing that is disrupting it. but if there's an earthquake in that means that there are unbalanced forces in that they cause an earthquake. a force is balanced if the two individual forces are of equal magnitude and of the opposite direction. And an object is said to be acted upon by an unbalanced force when there is an individual force that is not being balanced by a force of equal magnitude and in the opposite direction.
