The three components that make up the structure of the atom are as follows:
Electrons (Negatively charged sub-atomic particles). Protons (Positively charged sub-atomic particles).Neutrons (Neutrally or no charge). What is the nucleus of an atom?The nucleus of an atom may be defined as the center of any atom that significantly consists of protons and neutrons.
Due to the positive charge on protons and neutral charge on neutrons, the nucleus of an atom is found to be positively charged.
The electrons are negatively charged sub-atomic particles which are always revolving around the nucleus of an atom.
While protons are positively-charged sub-atomic particles that are present in the nucleus of an atom. And Neutrons are neutral or no charge sub-atomic particles that are present in the nucleus of an atom along with protons.
Therefore, the three components of atom has been significantly described with respect to their charge and specific locations within atom.

All Hawaiian honeycreeper bird species have similar skeletal and muscle structures. However, each Hawaiian honeycreeper species has a bill specialized for eating certain foods. What would a scientist most likely conclude based on this observation? Artificial selection shaped the bill for eating certain foods. Increased genetic variation resulted in similar skeletal and muscle structure. Changes in each honeycreeper species occurred independently, but resulted in similar traits. Honeycreepers arose from a single species that migrated to Hawaii and adapted to different niches over time.
Answer:
The correct answer is - Honeycreepers arose from a single species that migrated to Hawaii and adapted to different niches over time.
Explanation:
All Hawaiian honeycreeper bird species share similar muscle and skeletal structures. This suggests that all Hawaiian bird species arose from a common ancestor and evolved due to different environmental conditions such as eating particular foods for particular species.
It is believed to be a single species of honeycreeper who migrated from the mainland to Hawaiin island and adapted to different niches over time by the process known as natural selection.

What happens when an antibody and antigen react?
Answer:
Antigen-antibody interaction, or antigen-antibody reaction, is a specific chemical interaction between antibodies produced by B cells of the white blood cells and antigens during immune reaction. The immune complex is then transported to cellular systems where it can be destroyed or deactivated.
Explanation:
Antibodies attach to a specific antigen and make it easier for the immune cells to destroy the antigen. T lymphocytes attack antigens directly and help control the immune response. They also release chemicals, known as cytokines, which control the entire immune response.

Explanation:
Name 1 hazard that has no forecast and 1 that does. Make sure you identify which is which.
Answer:
As other natural hazards, landslides are difficult to predict, and their forecasts are uncertain. The uncertainty depends on the poor understanding of the phenomena that control the slope failures, and on the inherent complexity and chaotic nature of the landslides. One that has forcast is volcanic eruptions.

B) fossils of plants and animals
C) continents are not currently moving
Eliminate
D. land features match up (like mountains) on different continents
The statement 'continents are not currently moving' does NOT support the theory of Continental Drift.
Continental drift is the hypothesis that posits the idea that continents moved (drifted) over geologic time on the surface of the ocean bed.According to this theory, all current continents were once joined together in a single supercontinent called Pangaea, which subsequently broke apart million years ago.The hypothesis of continental drift has been nowadays replaced by the idea of plate tectonics.In conclusion, the statement 'continents are not currently moving' does NOT support the theory of Continental Drift.

Why do you think
organisms in the
same kingdom are
not all identical?
Answer:
Evolution, mutation, and adaptation
Explanation:
Since different organisms adapt to different environments and receive different mutations, they adapt differently and slowly change. That is why there are different species of birds, just look at the galapagos islands, there are thousands of species of finches that changed to survive on each island. The same could be said for every organism since the early organisms that we evolved from were widespread, some evolved differently than others, leading to different fish, different lizards, different early mammals, and so on. That is why humans look different than dogs or cats, we evolved best to our environment so we could survive.
Answer:
Though they are in the same kingdom which makes them makes the species they are built of different genes received from each parent.

Answer:
1. The daughter cells are genetically identical because they each contain the same diploid chromosome complement as the original parent cell. It can be seen in the stages shown above that mitosis maintains the chromosome number or complement of a cell.
2. Much of the growth in an adult is attributed to the growth plate in the bones, which is line of cells at each end of the bone that divides rapidly during puberty. As the bones elongate, the muscles also elongate as they are stimulated to grow by stretching and hormonal changes. When puberty is completed, the growth plate calcifies into solid bone and can no longer grow. Muscles can continue to enlarge with athletic activities and can sometimes split with excessive force, but muscle cells typically do not continue to divide. Cells such as your skin, hair, and interior mucus surface cells continue to divide because they are in direct contact with things from the outside world. Bone marrow also continually divides to produce red and white blood cells. Many other cells in your body do not continue cell division.
3. The number of Chromosomes stay the same when the cell divides because before a cell divides it produces new copies of the Chromosomes in the nucleus so when division takes place two genetically identical 'daughter cells', containing the same genes, are formed.
4. – in cells capable of dividing, the period between cell divisions is called interphase – cells spend most of their time in interphase because this is the phase where they perform their functions (obtaining energy, synthesizing products, repair damage, fight disease, duplicate their genetic material and get ready for division)
5. Asexual reproduction is a type of reproduction that does not involve the fusion of gametes or change in the number of chromosomes. The offspring that arise by asexual reproduction from either unicellular or multicellular organisms inherit the full set of genes of their single parent. Asexual reproduction is the primary form of reproduction for single-celled organisms such as archaea and bacteria. Many eukaryotic organisms including plants, animals, and fungi can also reproduce asexually. In vertebrates, the most common form of asexual reproduction is parthenogenesis which is typically used as an alternative to sexual reproduction in times when reproductive opportunities are limited. While all prokaryotes reproduce without the formation and fusion of gametes, mechanisms for lateral gene transfer such as conjugation, transformation and transduction can be likened to sexual reproduction in the sense of genetic recombination in meiosis.
6. Since each of the parent cell’s chromosomes were replicated during interphase, there are two copies of each chromosome in the cell during prophase. Once the chromatin has condensed into individual chromosomes, the genetically-identical chromosomes come together to form an “X” shape, called sister chromatids .

Professor Danielle conducts an experiment on chloroplasts by deactivating several enzymes used for light-independent reactions. All components of light-independent reactions remain present. Would the light-dependent reactions proceed normally? Explain.
PLEASE HELP!!!!
Answer:
NO.
Explanation:
The process of reaction of CO2 with H20 in the presence of enzyme, chlorophyll and sunlight is called photosynthesis. It has two stages: It is referred to as light dependent stage when it occurs during the day and light independent stage when it occurs at night.
The primary enzyme likely to be deactivated by the Professor is ribulose bisphosphate Carboxylate Rubisco. This is the most important enzyme in plants that catalysis the fixation of Co2 with 5C- ribulose bisphosphate Carboxylase (RuBP) to form3C -Glycerite -3-phospate.(GP).
The GP is reduced by NADP with ATP to form Triose Phosphate (TP). This is the point of glucose production in plants,
The majority of the TP is used for RuBP, hexose phosphates for starch productions, fatty acid and glycerol for cell membrane. Amino acids are also produced from TP. This is known s Calvin Cycle.
If the enzyme Rubisco is deactivated, the above process cannot occur, thus the basic macronutrients and enzymes for the survival of plants for photosynthesis(light dependent stage) can not occur.
Answer:
No, the reaction will not take place normally.
Explanation:
Chloroplasts serves as a site for photosynthesis in plants. The process of photosynthesis which is essential for plants to make food occurs in two elaborate reactions namely:Light-dependent Reaction: Where chlorophyll takes energy from the sunlight and preserves it as chemical energyLight-independent Reaction: Which occurs after light-dependent where the energy is used from the light-dependent reaction to synthesize CO2 into carbohydrates. The Light-independent reaction occurs in the stroma in the presence of CO2; Ribulose-1,5-biphosphate ( RuBP) and an enzyme called (RuBisCO) Ribulose-1,5-biphosphate carboxylase/oxygenase which catalyzes the process. If Professor Danielle deactivates RuBisCO then the process of Calvin Cycle results in the end product of glucose by the process of fixation, reduction, and regeneration. The process will immediately cease depriving the plant of all the essential macronutrients produced as the end result of the Calvin cycle i.e., glucose, starch, amino acid, and fatty acid. This deprivation of nutrients will eventually affect the synthesis of ATP and formation of NADPH as food deprivation would affect the normal functioning of cell organelles.For more information:
