please help me out, name all 3 parts of the atom.
In the atom, the arrow 1 depicts the proton. The arrow 2 depicts the neutrons, and the arrow 3 depicts the electrons. All three of these are subatomic particles.
What is an atom?An atom is the fundamental structural unit of matter. It consists of protons, neutrons, and electrons. Electrons are negatively charged particles that are present outermost shell of the atom, while protons are positively charged particles that make up the core of the atom. The neutron doesn't have any charge.
Both neutrons and protons make up the core of an atom, while electrons revolve around them. A neutral atom has equal numbers of protons and electrons. Example: the sodium atom.
Hence, the atom showing arrow 1 is a proton, arrow 2 is a neutron, and arrow 3 is an electron.

Indicate which of the following statements is TRUE. Group of answer choices Covalent bonds connect nucleotides in a strand; noncovalent interactions hold strands into a double-stranded structure. Uracil is similar to thymine except that uracil lacks a methyl group on the carbon at position 5 on the carbon-nitrogen ring. Frederick Griffith demonstrated that a transforming chemical from dead bacteria could change the genetic information of living bacteria. The pyrimidine bases in nucleic acids are cytosine, thymine, and uracil. All of the above statements are true.
Answer:
The answer is "All of the above statements are true".
Explanation:
In the given-question all choices were true, which can be defined as follows:
The covalent bonds are linked to a range of nucleic acids. Non-covalent encounters involve a dual washed ashore system. The Uracil is just the same as pyrimidines, except that at position 5 throughout the carbohydrate ring it lacks in the methyl group in carbon. Frederick-Griffith proved a possible change throughout the genetic material of bacterial cells with both the morphing chemical from dead bacterial cells. Cytosine, thymine, and uracil are pyrimidine fundamentals in nucleic acids.Soil moisture influences both hydrological and agricultural processes and is part of the water and energy cycles through ________.

2) IV: The extension of the rubber band above original length in centimetres
DV: The distance flown by the rubber band
Hypothesis: The potential energy stored in the rubber band by pulling will be transformed into kinetic energy and the larger the extension, the larger the stored potential energy, and the larger the resultant kinetic energy, the higher the velocity and the further the distance flown

DV: The distance flown by the plane
Hypothesis; The glide of the airplane is a factor of the wings span increased wingspan increased glide and increased travel distance
4) IV: Presence of more light

Hypothesis: Photosynthesis, which is the conversion of carbon dioxide and water into glucose and oxygen in the presence of Sunlight is essential for plant growth and the more the presence on light is increases the higher plant will tend to grow
5) IV: Amount of vinegar in the canister
DV: The height a rocket will launch
Hypothesis: With a given amount of baking soda, in the canister a little amount of vinegar causes a delayed launch but an increased build up of carbon dioxide resulting in higher height reached than when more vinegar is used in which case the lift off will be more rapid but the power will be lesser and the height reached reduced
6: IV: Surface area of the coin
DV: The number of drops held
Hypothesis: Due to surface tension and cohesion which are properties that increase with surface area and as such a coin with a larger surface area holds more water drops

Imagine an invertebrate that lives in an estuary where salinity varies cyclically with the tides. If this individual is able to adjust the salt concentration of its body fluids, its salt concentration will have:____. a. a cyclic variation depending upon when the animal drinks. b. regular variations that range from large to small. c. slight fluctuations that are kept within a narrow range. d. a cyclic variation opposite that of the surrounding water.
Answer: Option C.
slight fluctuations that are kept within a narrow range.
Explanation:
An invertebrate that lives in an estuary where salinity varies cyclically with the tides. If this individual is able to adjust the salt concentration of its body fluids, its salt concentration will have slight fluctuations that are kept within a narrow range so has to maintain homeostasis and prevent the cells of the the invertebrate from not shrinking which can be due to the salt solution (Hypertonic).
Estuary is an area of water or shorelines where river meet the ocean. It normal do have concentration of salts. Organisms that live in estuaries must be able to adapt to their dynamic environments, wich is due to variations in water chemistry includes salinity, as well as physical changes like the rise and fall of tides.

reaction that takes place in the chloroplasts of green plant cells, where chemical
energy is used to convert carbon dioxide and water into glucose and oxygen."
A. No errors
B. "water" and "oxygen" should be switched
C. "chemical" should be "light"
D. "chloroplasts" should be "mitochondria"
Answer:
It is 'C'
Explanation:
The chemical reaction that occurs in the chloroplast is:
6CO₂ + 6H₂O → C6H₁₂O₆ + 6O₂
The electromagnetic energy of sunlight is converted to chemical energy in the chlorophyll-containing cells of photosynthetic organisms. The granum stores the photon particles from light and converts its energy into chemical energy to convert carbon and water into glucose and oxygen.

Explanation:
The arrangement of leaves that provide maximum exposure to sunlight is referred to as leaf phyllotaxy that reduces overlapping and overshadowing of leaves and supports maximum photosynsthesis.
The contains numerous chlorophyll molecules that trap the light energy for the oxidation of water and producing oxygen (O2) atoms required for carbon (IV) oxide reduction in light-independent, which takes place in the stroma of the chloroplast.
Hence, the correct answer in a sequential manner is as follows:
phyllotaxy
