Hypothesis is a proposed explanation which is made on the basis of given experimental data taken as starting point for further investigation. All hypothesis test are conducted in a same manner fiollowing the four main steps:
1. State the hypothesis
2. Formulate an analysis plan
3. Analyzing the data obtained
4. Final step is to analyze the results
There are three types of variables taken in an experiment:
1. Independent variable: light, temperature, humidity
2. Dependent Variable: these depends upon the other variable. changes in the independent variable may cause the dependent variable to change, for example, growth of plant is a dependent variable which depends upon the amount of light(independent variable), the plant receives
3. Controlled Variable: these variable can be controlled and prevented from being change like ty[pe of plant, type of soil

What reaction is being catalyzed in this experiment? 2. what is the name of the enzyme in this experiment? what is the substrate?
Catabolism is the reaction that is being catalyzed in this experiment. The enzyme in this experiment is catalase. while the substrate is 3% hydrogen peroxide.
Further details
Enzyme
They are made up of proteins and act as catalyst inside living cells. They speed up the rate of reaction without being used permanently and without any change in their structure. A reaction is a procedure that changes over at least one substance (known as reagents, reactants, or substrates) to another kind of substance (the item). Benefit of using an enzyme is that it can be used repeatedly in the same reaction.
Substrate
It is a molecule followed by an enzyme. A substrate is stacked into the dynamic site of the enzyme, or the spot that enables weak bonds between the two particles.
Catabolism
It is the set of metabolic pathways in which larger molecules are breakdown into smaller ones and energy releases during these reactions which can be used to perform various functions. For example, larger molecules like polysaccharides, lipids, nucleic acids, and proteins are break down into smaller units as monosaccharides, fatty acids, nucleotides, and amino acids.
Catalase
Catalase is a typical enzyme found in almost all living beings presented to oxygen, (for example, microbes, plants, and living animals). It catalyzes the decay of hydrogen peroxide to oxygen and water. It is a significant enzyme shielding the cell from oxidative harm by responsive oxygen species.

What characteristic of beans enable you to use them as models for atoms of different elements?
Just as is the case of the isotopes of an element, the individual masses of beans of the same type are very similar but not identical. Also, similar to atoms of different elements, the average masses of different types of beans are different. These characteristics enable us to use them as models for atoms.
What organism is most affected by the accumulation of waste?
Describe in which ways are the new cells (daughter cells) similar to parent cells
Answer: Through Mitosis.
Explanation:
Mitosis is a type of cell division in which a single parent divide or replicate to produce two daughter cells that are identical to the parent.
In mitosis, the daughter cells contain the same number and type of chromosomes as the parent.
The parent transmit the same number of chromosomes or type to the daughter cells which make them to be similar.
The phoshorous cycle differs from the carbon cycle in that: none of the above the atmosphere does not contribute to part of the phosphorus cycle plants play a role in the carbon cycle, but have no role in the phosphorus cycle there is little or no human impact on the phosphorus cycle phosphorus is not a critical component of living organisms
The phosphorus cycle differs from the carbon cycle as it does not involve the atmosphere, instead it is often the limiting nutrient in ecosystems and cycles through geologic processes. Human activities affect the phosphorus cycle through the use of fertilizers, and phosphorus is critical for organisms, being part of nucleic acids and bones.
Explanation:The phosphorus cycle differs from the carbon cycle notably in that the atmosphere does not contribute significantly to the phosphorus cycle. While carbon cycles quickly between organisms and the environment through processes such as cellular respiration and photosynthesis, phosphorus is often the limiting nutrient in ecosystems and does not have a gaseous form that is readily available to organisms. Instead, phosphorus typically cycles through geologic processes like weathering and erosion, water drainage, and the movement of continental plates. In aquatic systems, particularly freshwater ecosystems, phosphorus is a critical component for growth. Plants do indeed play a role in the phosphorus cycle, aiding in the uptake of phosphorus from the soil with the help of mycorrhizal fungi.
It is not true that there is little or no human impact on the phosphorus cycle; excessive use of phosphorus in fertilizers can lead to nutrient overload and eutrophication in water bodies. Lastly, phosphorus is absolutely a critical component of living organisms, comprising nucleic acids, phospholipids, and as calcium phosphate, it is a major element in bones.

The common characteristic of all deserts is _____.
low annual rainfall
hot temperatures
simple ecosystems
mineral-poor soil
Answer: low annual rainfall
Explanation:
Deserts are the arid regions which receives very low annual rainfall as compared to other biomes of the world. The region exhibit higher potential evaporation rate over the rate of precipitation. The deserts are divided into three types depending upon their locations. Subtropical deserts these exhibit hottest climatic conditions and rapid evaporation. Cold winter deserts, the average temperature is cool. Polar deserts form in the polar regions as all the moisture in these areas is locked up by the freezing ice.
The ecosystem of the deserts may vary from simple to complex depending upon the diversity of the living organism, climate conditions and water. The soil of some of the desert is fertile and rich in minerals not every desert exhibit nutrient poor soil.
On the basis of the above explanation, low annual rainfall is the common characteristic of all the deserts.

Which kinds of synovial joints can move in two (and only two) planes of the body?
Final answer:
Condyloid and saddle joints are synovial joints that can move in two planes of the body, allowing movements in flexion-extension and abduction-adduction.
Explanation:
The synovial joints that can move in two planes of the body are the condyloid and saddle joints. Condyloid joints allow for movement in two planes: flexion and extension, and abduction and adduction, as seen in the radiocarpal joint of the wrist. Similarly, saddle joints also offer biaxial movement and can be exemplified by the joint between the trapezium carpal bone and the first metacarpal bone at the base of the thumb. These joints can perform movements like the sequential combination of flexion, extension, abduction, and adduction, which together produce circumduction.
If the environment change suddenly for example because of global warming, do you think generalist or specialist species would be better able to adapt and avoid going extinct? Why?
Generalist species would be better able to adapt and avoid extinction compared to specialist species in the case of sudden environmental changes like global warming.
Explanation:In the case of sudden environmental changes like global warming, generalist species would be better able to adapt and avoid extinction compared to specialist species. Generalist species are able to tolerate a wide range of environmental conditions and utilize different resources, which provides them with greater flexibility in changing environments. Specialist species, on the other hand, are highly adapted to specific ecological niches and rely on specific resources, making them more vulnerable to changes in their environment.

How many phosphoester (phosphate ester) and phosphoanhydride bonds are in adenosine monophosphate (amp) and adenosine diphosphate (adp)?
Answer: The correct answer is -
The number of phosphoester bond in-
AMP (adenosine monophosphate) = 1
ADP ( adenosine diphosphate) = 1
The number of phosphoanhydride bonds in -
AMP = 0
ADP = 1
Phosphoester bond is formed when the alpha phosphate (that is the first phosphate) present in ADP and AMP links to the 5' carbon of ribose sugar through oxygen.
On the other hand, Phosphoanhydride bond is formed between two phosphate. As ADP has two phosphate, thus it contains one phosphoanhydride bond and the first phosphate is linked to ribose via one phosphoester bond.
AMP has single phosphate, so no phosphoanhydride bond is there, only one phosphoester bond is present in it.
A child has sickle-cell disease ( ss ) but neither parent is ill. What must be true of her parents’ genotypes?
Answer:
Her parents are heterozygous carrier for the disease and have genotype "Ss"
Explanation:
Sickle cell disease is a recessive disorder and is expressed in homozygous recessive genotype only.
Since the child is affected with sickle cell anemia, her genotype is "ss".
To get "ss" genotype, both her parents should have at least one copy of "s" allele. Since both the parents are not affected by the disease, they are heterozygous for the allele. Both the parents have genotype "Ss" and are serving as carriers for the disease.
