Answer:
Atoms have three particles: protons, electrons, and neutrons. The nucleus contains protons and neutrons. The outside regions of the atom are called the electron shells and have electrons.
Explanation:
hopefully this helps you. :)
pls mark me brainlest ;)
Answer:
An atom is a tiny indivisible particle.It is made up of three subatomic particles named as electrons,protons and neutrons.Protons and neutrons are located inside the nucleus of an atom and electrons revolve around the nucleus in different energy levels or shells.
Protons are positively charged.Mass of protons is equal to the mass of electrons.Neutrons are neutral.Electrons are negatively charged.

Coloration in mockingjays is determined by a single gene. The G allele leads to grey colored feathers and the g allele leads to all white feathers. If two heterozygotes are crossed, what would be the phenotypic ratio in the F1 progeny? What would be the genotypic ratio in the F1 progeny
Answer:
F1 genotype = 1: 2: 1
F1 phenotype = 3:1
Explanation:
given data
G = allete for grey colour feather
and
g = allele for white colour fether
and
Gg = genotype of heterozygotes
we do here cross of two heterozygotes that is
parantal generation Gg × Gg
⊥ ⊥
G g G g
gametes ⇒ F1 generation
F1 genotype = 1: 2: 1
F1 phenotype = 3:1
The wild-type eye color in the fruit fly Drosophila melanogaster is dark red, as a result of a mixture of bright red and brown pigments. "Enzyme A" is encoded by the "a" gene, and is required to synthesize the bright red pigment. A lack of red pigment results in a somewhat brown eye color. You cross two fruit flies who are heterozygous for a recessive mutation that completely inactivates the "a" gene. What proportion of their offspring will have a recessive eye color phenotype?
Answer:
1/4 or 25%
Explanation:
Let the wild-type eye color be represented by allele A. The mutant's eye color would be represented by allele a.
The genotype of fruit flies that are heterozygous for a recessive mutation that inactivates gene 'a' ( and therefore results in mutant eye color) would be Aa.
If Aa and Aa are crossed:
Aa x Aa
progeny: AA Aa Aa aa
The proportion of the offspring that will have a recessive eye color phenotype (aa) would therefore be 1/4 or 25%.
What compound is this?
Carbohydrates
Lipids
Nucleic acids
Proteins
Answer:
Nucleic acids.
Explanation:
Extremely helpful Bio mnemonics to remember are:
Carbohydrates & Lipids - CHO
Proteins - CHON
Nucleic acids - CHONP
Because of the "CHONP" mnemonic, I was immediately able to recognize the compound as a nucleic acid after seeing the "P", which represents phosphorous.
Carbohydrates, lipids, nor proteins will include "P"; only nucleic acids.

Research Problem: You come across three new species of primates that all cohabitate the same forested area. No one has looked at the behavior of these monkeys before so there is lot to discover about each species. You and a fellow researcher are interested in describing the diet of each of these species (Do they eat fruits? Leaves? Insects? Tree-sap? A combination of sorts?). Your fellow researcher has determined that her hypothesis is that two of the monkeys primarily eat fruit, while one of the monkey species eats tree sap.
Answer:
there are three different species.
Explanation:
There are three different species of monkey according to the hypothesis because all monkey species have different feeds i. e. one feed on the fruits while the other feed on the tree sap. It also shows that two monkey species have same feed i. e. eating fruits while one specie feeds on tree sap. This hypothesis also shows that no specie of monkey feeds on leaves and insects present on the trees.

Gastrin secretion in response to elevated ph within the stomach is an example of:__________.
Answer:
It is an example of enzyme activation through the pH of the environment surrounding the enzyme.
This phenomenon is called proenzyme, proenzymes are inactive enzymes that, due to chemical changes in the environment that vary, are activated or not depending on these.
Explanation:
Proenzymes, generally the best known or named, are found in the digestive system, where the sequential digestion of food is essential, with an order, and the enzymes must be controlled or activated at certain moments of digestion.
Proenzymes can be activated by the presence of chemicals, pH acids and even pH alkalinity, the change of the medium is what gives the enzyme permission to start with its reaction effect.
Usually this happens with enzymes that must be controlled, and that their activity must be in certain periods so as not to generate pathologies or even destroy a tissue of the organism.

which combination of the state and a substance in that state is correct
Answer:
Change of state of matter: In physics, we call the process of changing matter from one state to another state as change of state of matter. They can be transformed into each other, so there are 6 kinds of physical changes: melting, solidification, vaporization, liquefaction, sublimation, and sublimation. Other states of matter such as: plasma state, super solid state, neutron state, Bose-Einstein condensed state, soft matter, etc.
Explanation:
1. State of matter: Since a large number of molecules that make up a substance are constantly performing irregular thermal motion, and different molecules perform thermal motion at different speeds, three states of matter are formed: solid, liquid, and gaseous. In science, we call the state of matter the state of matter.
2. How to judge what kind of state change is happening: The key is to find the two states of the substance before and after the change in state, and then compare them according to the definition, and then you can draw the correct conclusion.
Three states, six changes and endothermic hveat release: Physical change
Melting: solid → liquid (endothermic)
Solidification: liquid→solid (exothermic)
Vaporization: (boiling and evaporation): liquid → gas (endothermic)
Liquefaction: (two methods: compressing volume and lowering temperature): gas → liquid (exothermic) Sublimation: solid → gas (endothermic)
Sublimation: gas state → solid state (exothermic)
(Note: The "heat" of "endothermic" and "exothermic" mentioned here refers to heat, not to thermodynamic concepts such as temperature, internal energy, calorific value, and specific heat capacity. That is, "absorbed heat" and The abbreviation for "release of heat." In physics, heat cannot say "how much heat it contains" or "how much heat it has", but can only say "how much heat is absorbed" or "how much heat is released")

2. Ivan and Braxton want to know if a stretching a rubber band at different lengths affects how far the rubber band will fly. They will use centimeters for all measurements. IV: DV: Hypothesis: 3. Will a paper airplane with longer wings fly farther than shorter wings?
Answer:
Independent variable: DIFFERENT LENGTHS OF STRETCHING
Dependent variable: DISTANCE RUBBER BAND FLIES
Hypothesis: IF a rubber band is stretched longer, THEN the distance it flies will increase
Explanation:
The hypothesis of an experiment is a testable explanation or suggested solution to an observed problem or asked question. In this experiment, the hypothesis can be: IF a rubber band is stretched longer, THEN the distance it flies will increase
Note that, this hypothesis can be tested to be true/untrue
Independent variable is the variable that the experimenter manipulates or changes in order to bring about a response. The independent variable in this question is DIFFERENT LENGTHS OF STRETCHING THE BAND.
Dependent variable is the variable that the experimenter measures in response to the independent variable. In this experiment, the measured/dependent variable is the DISTANCE RUBBER BAND FLIES

Explanation:
After DNA replication, the chromosome consists of two identical (long) threadlike strands called sister chromatids. These sister chromatids are double stranded and are joined together at the centromere (in the centre by a protein complex called cohesin. The closest option to cohesin is option C.
What conditions are needed to form organic molecules from inorganic molecules? (A: Abundance of oxygen and the ozone layer) (B: Active volcanoes and very cold temperatures) ( C: Presence of inorganic molecules with lightning and intense radiation) (D: Low levels of ultraviolet radiation and a specific mixture of gases).
Answer:
c
Explanation:
the theory suggest that formation of organic molecules takes places by the help of inorganic material along with lightening and intense radiation
Lightning and strong radiation in the presence of inorganic compounds. Thus option C is incorrect.
What is abiogenesis?Abiogenesis is the process of forming organic molecules from inorganic ones.
This is thought to be how the first organic compounds were formed around 3.8 billion years ago on early Earth. The classic Miller–Urey experiment from 1952 aimed to recreate the early earth's conditions. They used electric parks to simulate lightning strikes in a glass with greenhouse gases such as methane, which are thought to have been key parts of the early Earth's atmosphere. This experiment resulted in the formation of primitive organic compounds.
