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.

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.

Answer:
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.

In what state is carbon dioxide in the atmosphere
CO2 exist in the earth'a atmosphere as a gas and in its solid state it known as dry ice.
What are the functions of carbon dioxide?Carbon dioxide is a chemical compound made up of molecules that each have one carbon atom covalently double bonded to two oxygen atoms. It is found in the gas state at room temperature.
CO2 plays various roles in the human body including regulation of blood pH, respiratory drive, and affinity of hemoglobin for oxygen (O2). Fluctuations in CO2 levels are highly regulated and can cause disturbances in the human body if normal levels are not maintained.
Carbon dioxide is an atmospheric constituent that plays several vital roles in the environment. It is a greenhouse gas that traps infrared radiation heat in the atmosphere. It plays a crucial role in the weathering of rocks. It is the carbon source for plants.

The picture shows the process of asexual reproduction in hydra. According to the illustration, all offspring are
-
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.

Explanation:
A researcher is studying a cornfield that has been recently abandoned by a farmer. By the end of one year, wild grasses begin to grow in the field. Explain whether this is an example of primary succession or secondary succession. Describe how the researcher can identify when a climax community is reached in the area that was a cornfield.
It is an example of secondary succession.
The community is considered a climax community once it has reached equilibrium, and the environmental conditions and species composition do not change very much.What is succession?Ecological succession is the process by which the mix of species and habitat in an area changes over time. Gradually, these communities replace one another until a climax community is reached.Example -A dirt field is plowed and left over the summer.-Over the summer, weeds start to grow on the field.
- After the weeds grow, small shrubs begin to take root.
- After a few years, trees begin to grow in the field.

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.

habitats would make mitosis a better reproductive option than meiosis?
Meiosis does not occur in archaea or bacteria, which reproduce via asexual processes such as mitosis or binary fission. ... Because the chromosomes of each parent undergo genetic recombination during meiosis, each gamete, and thus each zygote, will have a unique genetic blueprint encoded in its DNA.
