Answer:
Because the atoms are held together by the interactions of electrons in their valence shells. Separating them therefore makes them less stable.
Explanation:
Thats why the energy that is stored in the chemical bond of a molecule is not destroyed when that molecule is broken down to smaller molecules
The atoms are held together by the interactions of electrons in their valence shells. Separating them therefore makes them less stable.
What is Chemical bond?
The energy that is stored in the chemical bond of a molecule is not destroyed when that molecule is broken down to smaller molecules.
When atoms are attracted to each other and join together to form a molecule, we call the connection between each atom a chemical bond. The bond “holds together” the atoms in the molecule, ion, or crystal.
Chemical bonding is the attraction between two or more atoms that allows them to be able to form a stable chemical compound. The specific nature of a chemical bond can vary, but the most commonly known are covalent and ionic bonds.
Therefore, The atoms are held together by the interactions of electrons in their valence shells. Separating them therefore makes them less stable.

How do air masses interact to form a hurricane?
A. A cyclone becomes slower and slower as pressure differences
between areas of low and high pressure decrease.
B. A cyclone rotates faster and faster as pressure differences
between areas of low and high pressure increase.
C. Cold, dense air flows toward the warmer, less dense air, so the
cold front ends up moving faster than the warm front.
D. Two air masses meet, but neither moves into the other one and
spiral wind results.
The major cause of air masses interaction to form a hurricane is that a cyclone becomes slower and slower as pressure differences between areas of low and high pressure decrease, hence option A is correct.
The low pressure area is pushed inward by air from nearby regions with higher air pressure, "new" air then warms up, gets humid, and rises as well.
The surrounding air swirls in to take the place of the rising heated air. The water in the air condenses into clouds when the warmer, humid air rises and cools.
More water vapor may be held in air that is warmer. Particularly during severe occurrences, the extra atmospheric moisture causes more intense rainfall.

4 Scientists want to know whether your genes or your environment has the biggest influence on your
behaviour
. To answer this question they compare identical twins that were separated at birth with
identical twins who grew up together.
a Suggest why identical twins separated at birth are ideal for these studies.
b What results would you expect if inherited variation turned out to be more important than
environmental variation in determining your behaviour? Pealse short answers I dont have enogh lines
Answer: a. Identical twins who grew up together are essential for these studies so that we can see if environment is really an influence or not. Maybe it could be a different case for each one of them. So by comparing them we can know.
b. The results of inherited variation would be that the offsprings would get the same type of characteristics from their parents while environmental variation is variation causedby the environment like heat, temperature, etc.

What is the role of these bacteria in the nitrogen cycle
Answer:
Prokaryotes play several roles in the nitrogen cycle. Nitrogen-fixing bacteria in the soil and within the root nodules of some plants convert nitrogen gas in the atmosphere to ammonia. Nitrifying bacteria convert ammonia to nitrites or nitrates. ... Denitrifying bacteria converts nitrates back to nitrogen gas

Raya conducts an experiment to study the effect of altitude on the growth of plants she gathered plant samples and places them on five different floors of a 20-story building identify the basic components of Ray experiment including the compounding variable
Answer:
Independent variable: ALTITUDE
dependent variable: GROWTH OF PLANTS
Confounding variable: STOREYS OF THE BUILDING
Explanation:
In an experiment, the basic components i.e primary variables that an experiment should contain, are the independent and dependent variables.
- The independent variable is the variable that is changed or manipulated in an experiment. In this experiment, the ALTITUDE of the plant is the independent variable.
- The dependent variable is the variable that responds to changes to the independent variable. It is the variable measured in an experiment. In this case, the dependent variable is the GROWTH OF THE PLANTS.
- The confounding variable is a variable that has an extra influence on the outcome of the experiment. In other words, the confounding variable has an impact on the dependent variable. In this case, the confounding variable is the STOREYS OF THE BUILDING.

Physical adaption
Explanation:
Physical adaptations are being described. Therefore option A is correct.
The observations described in the table refer to physical adaptations in birds.
Physical adaptations are structural or anatomical features that have evolved over time to help organisms better survive and thrive in their environments.
In the case of bird dissection, the observed features such as hollow bones, lungs, flight muscles, and fused bones are all physical traits that aid in the bird's ability to fly.
Hollow bones reduce the bird's overall weight, making flying easier. Well-developed flight muscles and fused bones enhance the bird's ability to generate lift and support its body during flight.
These physical adaptations are crucial for birds' survival and successful adaptation to their aerial lifestyle.
Therefore option A is correct.

what else is missing from this equation that a plant needs in order to do photosynthesis
Answer:
The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2.
Explanation:
This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products
The equation of photosynthesis is 6 CO₂ +6 H₂O[tex]\rightarrow[/tex] C₆H₁₂O₆ + 6 O₂ in the chemical form.
What is photosynthesis?
It is defined as a process by which plants and other photosynthetic organisms convert the light energy in to chemical energy through the process of cellular respiration.
Some of the energy which is converted is stored in molecules of carbohydrates like sugar and starches which are made up of from carbon dioxide and water . Photosynthetic organisms which can perform photosynthesis are algae and cyanobacteria. Photosynthesis is largely responsible for producing and maintaining the content of oxygen in earth's atmosphere.
The process begins with proteins absorbing light energy which are called reaction centers and contain a green pigment which is called chlorophyll . In plants ,these pigments are present inside organelles called chloroplasts while in bacteria they are present in plasma membrane.

-
ning
-19
A) genetically varied.
B)
genetically identical to the parent.
slightly similar to the parent.
D)
genetically very different from the parent
Answer:
There is no illustration, but the question can be answered based on general understanding of reproduction. The answer is:
B) genetically identical to the parent.
Explanation:
Reproduction, which is the process by which organisms produce their offsprings, can be done in two major ways namely: sexually and asexually. The asexual reproduction involves only one parent that undergoes division to form two daughter cells.
Since there is no exchange of genetic material between two parties as it involves only a single organism, the offsprings will be GENETICALLY IDENTICAL to the parent cell. This is the case of Hydra in this question that underwent asexual reproduction. All of the offsprings of this mode of reproduction will be GENETICALLY IDENTICAL i.e. have the same genetic composition as their parent.
