Explanation:
Answer:
Plants can't walk to different places and take their seeds somewhere else they have developed other methods to move their seeds. The most common methods are wind, water, animals, explosions and fire. Dandelion seeds float in the wind.

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.

How does competition limit the dispersal of organisms? *
Answers
Answer:
Three factors that limit dispersal of a species are physical barriers, competition, and climate. Physical Barriers include water, mountains, deserts, and canyons because these barriers are hard for most organisms to cross, they limit the movement of organisms.
If an animal has to pass through another animals territory to disperse, that animal may be killed or injured in the process, so it may opt not to move or not to move as far as it should.

Answers
Please mark me the brainliest ty
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.

B. The protist is a plant-like dinoflagellate because it

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.
Answers
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

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.
Answers
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.

Are all electrolytes the same in their indications? Explain
Answers
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.

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
Answers
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.
