Answers

Answer:

have variation that can be passed from one generation to the nextsurvive longer than another organismhave adaptations to their environment. have differential reproductive success.

Explanation:

Naturla selection is the survival and reproduction of individuals due to different phenotypes. The naturla selection represents a mechanism of evolution and changes in traits of species.

In order for natural selection to occur, organisms must :

have a variation that can be passed from one generation to the next.have differential reproductive success.

Natural Selection is a mechanism of evolution that occurs when there is a heritable variation for a trait and individuals with one version of the trait have greater reproductive success than do individuals with a different version of the trait.

In order for natural selection to occur, three conditions must be met:

There must be variation for the particular trait within a population.The variation must be inheritableIndividuals with one version of the trait must produce more offspring than those with a different version of the trait.

Thus,

In order for natural selection to occur, organisms must :

have a variation that can be passed from one generation to the next.have differential reproductive success.

Answer:

There are no options in this question, the options are as follows:

A. Antibiotics build up immunity, and antivirals increase white blood cells.

B. Antibiotics treat the symptoms, and antivirals destroy the causing organism.

C. Antibiotics are in liquid form, and antivirals are in mist form.

D. Antibiotics treat patients who have Staphylococcus, and antivirals treat patients who have the flu.

The answer is D

Explanation:

Specific drugs are used to curb infection or diseases caused by specific pathogens. An infection can be caused by either bacteria, virus or fungi. Considering their different mechanism of infection, viral infections are treated with the use of ANTIVIRAL DRUGS while bacterial infections are treated with the use of ANTIBIOTICS.

According to this question, staphylococcus is a bacterial genus and hence, patients with staphylococcus can be treated with antibiotics while flu is a viral disease, hence can only be treated with antivirals.

Chemosynthesis _______. Question 11 options: uses energy derived from hydrocarbons and hydrogen sulfide in place of solar energy produces carbohydrates and sugars occurs around hydrothermal vents near the oceanic ridge system Both a and c are correct. All of the above are correct.

Answers

Answer:

The answer is all of the above are correct.

Explanation:

Chemosynthesis occurs in bacteria and other organisms and involves the use of energy released by inorganic chemical reactions to produce food. All chemosynthetic organisms use energy released by chemical reactions to make a sugar, but different species use different pathways. For example, at hydrothermal vents, bacteria oxidize hydrogen sulfide and add carbon dioxide and oxygen to produce sugar, sulfur, and water:  

CO2 + 4H2S + O2 ⇒ CH20 + 4S + 3H2O.

Chemosynthesis is the process by which food (glucose) is made by bacteria using chemicals as the energy source, rather than sunlight. Chemosynthesis occurs around hydrothermal vents and methane seeps in the deep sea where sunlight is absent. During chemosynthesis, bacteria living on the seafloor or within animals use energy stored in the chemical bonds of hydrogen sulfide and methane to make glucose from water and carbon dioxide (dissolved in seawater). Pure sulfur and sulfur compounds are produced as by-products.

What would be considered a quantitative observation

Answers

Answer:

height of radish seedlings is measured.

Quantitative observation is a method of collecting objective data that is largely focused on numbers and values — the phrase means "related with, of, or portrayed in terms of a quantity." Sending out surveys, questionnaires, or polls is a common method of quantitative observation.

quantitative observation include age, weight, height, length, population, size, and other numerical values while, qualitative observation are color, smell, taste, touch or feeling, typology, and shapes.

7. Substitution mutation

8. Substitution mutation

9. Frameshift mutation

Explanation:

A substitution mutation is any kind of mutation that involves replacement of one or more nucleotide base by another in a sequence.

A frameshift mutation, on the other hand, is a mutation that changes the reading frame of the sequence. Two types of mutations cause frameshift viz: insertion and deletion mutation.

In the following sequences, mutation has occured as follows:

7. UGU-CCG-GAA-CGA to UGC-CGG-GAA-CGA - Substitution mutation has occured because nucleotides C and G has replaced C and U in the first and second codons respectively.

8. GAA-CGU-AGC-GGU to GAU-CGU-AGC-GGU- A substitution mutation because nucleotide U has replaced A in the first codon.

9. UGU-UUC-CCU-UAA to UGU-UCC-CUU-AA - A frameshift mutation because nucleotide U has been removed from the second codon, hence, causing a change in the reading frame.

Fossils: In the oldest rocks area unit fossils of the best organisms and within the newest rocks area unit fossils of additional advanced organisms.

 

Explanation:

The evolution theory is supported by multiple sorts of evidence: homologous structures show common ancestry, whereas similar selective pressure will manufacture similar variations. analogous structures (beneficial features).

In the oldest rocks area unit fossils of the best organisms and within the newest rocks area unit fossils of additional advanced organisms. This supports Darwin's organic process theory, whereby straightforward life forms {progressively|increasingly|more and additional} evolved into more advanced. Proof of adolescence forms comes from fossils.

Fruit trees in a forest are an important habitat for a bird species and were historically a major source of food for a rodent species. Over time, the rodent species shifted their feeding behavior from fruit trees to nut trees. As rodent behavior changed, the density of fruit trees decreased, which caused significant decreases to the bird population. What kind of effect did the change in rodents exert on bird population size?

Answers

Answer:

The bird population might have to migrate in search for food or may decline in numbers.

Explanation:

This is a concept of primary producers that is trees and secondary consumers that is mouse and bids. Due to the decline in raw material available the mouse population declines and this also affects the secondary consumers that are birds of prey like hawks, owls etc.
