Darwin studied actual birds on the Galapagos Islands instead of using a simulation, as you did in this lab. Studying natural selection in the field can be challenging. List at least three possible challenges Darwin might have faced.
Answer:
1. Darwin did not know how genetic material passed from one generation to the next because Mendel's laws of heredity had not yet been formulated
2. Finches have many phenotypic adaptations that can not be observed easily
3. Phenotypic traits are expected to evolve slowly, thereby taking many generations
Explanation:
In the Galapagos Islands, Darwin observed that there were many varieties of finches that showed variation in the size and shape of their beaks. Darwin determined that finches' beaks evolved in response to environmental changes (finches' beaks were different in different islands). Darwin had several challenges to make this discovery. First, Mendel's laws of heredity had not yet been formulated, thereby difficulting the analysis of quantitative traits (in this case, finches' beak) which are the result of the combined action of many genes and the environment. Second, finches (as well as all species) possess many phenotypic adaptations, thereby difficulting the study of single traits in an evolutionary context. Finally, phenotypic changes are gradual and therefore descendence with modification cannot be easily recognized by observation in the field.
Answer:
Traits other than beak type might affect natural selection.
It could take many generations to observe adaptions to a population.
The environment may be complex and hard to study.
Changes in the environment may occur faster or slower than changes to the birds
The birds may be interdependent with other organisms that may change, too.

Under which condition is the speed of cellular chemical reactions within a cell most likely to decrease?
Answer:
The products of the reaction decreases
Explanation:
When the product are formed in a chemical reaction it leads to decrease in chemical reaction rate in a cell.
What Factors Affect the Speed of Chemical Reactions?Some chemical reactions are fast and some are slow due to presence of different factors.
The collision between the reactants specially at the reactive site of the molecule will be needed to complete the chemical reaction.
So larger the size of reactant slower be the reaction or even no reaction occur due to less collision.
The more surface area of the particle lead to more collision and faster the reaction.
More Concentration of chemical reactants lead to faster the reaction rate. Higher the pressure of the reactant lead to faster the reaction rate.
Increasing in temperature can also lead the molecules move faster, average kinetic energy of the molecule can also increases.

Excess Post Exercise Oxygen Consumption (EPOC) occurs, most often as a result of
a. High intensity interval training (HIIT)
b. Low intensity endurance training
C. Short term, moderate intensity strength training
d. ALL of the above
Next Previous
Answer: all of these exercise modes, but less likely with low intensity endurance training.
Explanation: exercise increases respiration requirement and therefore oxygen requirement. Energy stores (glycogen) are used first but with then the body needs to maintain energy production at an increased level. There is a limit to how quickly energy can be supplied from respiration and additional energy is generated anaerobically with the by product being lactic acid. An ‘oxygen debt’ is incurred because normal homeostasis requires the metabolism of lactic acid and energy for repair of any cellular damage, requiring oxygen consumption above what is required for normal resting metabolism. It is possible in elite athletes that during low intensity training they may be able to operate aerobically for an extended period.

Are all electrolytes the same in their indications? Explain
Answer: Electrolytes are minerals in your body that have an electric charge. They are in your blood, urine, tissues, and other body fluids. Electrolytes are important because they help Balance the amount of water in your body.Balance your body's acid/base (pH) level .Move nutrients into your cells, Move wastes out of your cells, Make sure that your nerves, muscles, the heart, and the brain work the way they should. Sodium, calcium, potassium, chloride, phosphate, and magnesium are all electrolytes. You get them from the foods you eat and the fluids you drink. The levels of electrolytes in your body can become too low or too high. This can happen when the amount of water in your body changes. The amount of water that you take in should equal the amount you lose. If something upsets this balance, you may have too little water (dehydration) or too much water (overhydration). Some medicines, vomiting, diarrhea, sweating, and liver or kidney problems can all upset your water balance. Treatment helps you to manage the imbalance. It also involves identifying and treating what caused the imbalance.

Which conclusion is best supported by the information?
A. The protist is an animal-like flagellate because it has
a flagellum.
B. The protist is a plant-like dinoflagellate because it
produces oxygen.
C. The protist is a plant-like dinoflagellate because it was
found in salt water.
D. The protist is an animal-like flagellate because it has
a nucleus.
Answer:
The correct answer is - B. The protist is a plant-like dinoflagellate because it produces oxygen.
Explanation:
Protists are a eukaryotic organism that is not a plant, animal, or fungi but definitely, they all arise from a common ancestor as these single-cell organisms with cell organelles like the nucleus. These shows similarities with all three kingdoms of the eukaryotes. It shows similarities with the animals they move and depend on the particle outside of their body for nutrition and energy.
Plants-like protists are the protist or dinoflagellates that present in freshwater, marine water perform photosynthesis and provide oxygen and glucose in the water for and maintain the oxygen in the water for the organism to breath.
Plant-like protists are essential to the ecosystem. They are the base of the marine food chain, and they produce oxygen through photosynthesis for animals to breathe

First image is the double helix and the second one is chromosome.
What are chromosomes?A chromosome is a long DNA molecule with part or all of the genetic material of an organism. In most chromosomes the very long thin DNA fibers are coated with packaging proteins; in eukaryotic cells the most important of these proteins are the histones.
Chromosomes allow DNA to be accurately copied during these cell divisions. So one more time. Chromosomes are found in the nuclei of our cells and allow DNA to be accurately copied during cell division.
Chromosomes are arranged in ordered haploid sets around the centre of the metaphase plate at mitosis in several grass species and hybrids.

O Viruses can have glycoproteins on their surfaces.
Activate
Go to Set
Type here to search
Answer:
Viruses replicate only inside host cells.
Explanation:
Viruses are not used as evidence to support the cell theory because they are not considered a cell and cannot carry out vital life processes without getting into host cells.
According to the cell theory, the cell is the basic unit of life, all living organisms are made up of cells and cells arose from preexisting cells. A virus that is not in a host cell is just a piece of DNA/RNA surrounded by a protein coat and is not capable of carrying out any life process for it to be considered living.
Viruses are only able to reproduce and multiply when they get access to a living host. They use the genetic mechanisms of the host to replicate their DNA/RNA using the lytic or lysogenic cycle. Hence, they are not used to support the cell theory.

Which statement BEST describes the effect of human urbanization on biodiversity in the Amazon
rainforest?
A
Human urbanization increases biodiversity because cleared land attracts more
species into an area
B
Human urbanization decreases biodiversity because habitats and resources are
lost to native species
С
Human urbanization increases biodiversity because of non-native species
introduced to the food web.
D
Human urbanization decreases biodiversity because limiting factors of the forest
ecosystem are reduced.
Human urbanization would generally decrease the biodiversity of any forest because habitats and resources are lost during the process of urbanization.
Urbanization refers to the process through which cities are created out of urban areas.Cities are created by removing vegetation and erecting infrastructures such as buildings, roads, bridges, etc. The removal of vegetation means that habitats of organisms would be lost as well as the biodiversity that constitutes the vegetation itself.Thus, urbanization would automatically lead to a loss of biodiversity in the Amazon forest.
