Which of these can be decomposed by a chemical change?
Answer:
B) CO
Explanation:
Chemical decompsition or breakdown is defined as the process in which a substance can be broken down into simpler compounds through chemical means.
CO or carbon monoxide can be decomposed by chemical change because it can be broken down into into carbon and oxygen.
While Co (cobalt), Cr (chromium), and Cu (coppoer) are present in its simplest form and can not be decomposed further.
Hence, the correct answer is "B) CO".

The difference between macroevolution and microevolution is that: Please choose the correct answer from the following choices, and then select the submit answer button. microevolution occurs in prokaryotes, whereas macroevolution takes place among eukaryotes. they take place on different time scales. microevolution involves changes to individuals within a population, whereas macroevolution involves changes to all of the individuals within a population. microevolution has been proven, whereas macroevolution is very speculative. macroevolution occurs with physical structures, whereas microevolution occurs with physiological traits.
Answer:
What is the difference between microevolution and macroevolution? Microevolution deals with changes in the gene pool of a single population. Macroevolution considers the broad pattern of evolutionary change over long periods of time and includes the origin of new groups.
Conalan wants to answer the quesionn does phosphrus affect tomato fruit production? Which statement represents a hypothesis that he can test to answer his question
Answer:
If phosphorus affects tomato fruit production, then plants that are fertilized with phosphorus will produce more tomatoes.
Explanation:
The available options to the question are:
If phosphorus affects tomato fruit production, then tomatoes that are fertilized with phosphorus will have larger leaves.
If phosphorus affects tomato fruit production, then phosphorus should be added to the soil during planting.
If phosphorus affects tomato fruit production, then adding phosphorus to the soil will make tomatoes taste better.
If phosphorus affects tomato fruit production, then plants that are fertilized with phosphorus will produce more tomatoes.
The correct answer here would be that "If phosphorus affects tomato fruit production, then plants that are fertilized with phosphorus will produce more tomatoes."
The hypothesis represents a tentative statement relevant to the research being carried out. What researchers do during the course of researching is to test the validity of hypotheses with experiments.
Since the main aim of the research is to find out if phosphorus affects tomato fruit production, the relevant hypothesis must effectively address the main aim of the research.
The production of tomato can only be measured from the yield of tomato fruits produced by the tomato plants. If phosphorus does indeed affect tomato fruit production, then the tomato plants that are supplied with the element will produce a higher yield of tomato fruit as compared to the ones without phosphorus.

The rate of heat production is increased by increasing muscle contraction by movement is: Shivering thermogenesis Non- Shivering thermogenesis Vasoconstriction Vasodilation
Answer:
Shivering thermogenesis.
Explanation:
The rate of heat production is increased by increasing muscle contraction by movement is shivering thermogenesis because nerve impulses are transmitted to the skeletal muscles by the hypothalamus which will result to contractions that will produce heat.
Shivering thermogenesis is Contraction-mediated heat production High intensity shivering activates large muscles and produce more glycolysis which is then use as the main source for heat production
what is mean by chromosomes?
Answer:
A chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.
A chromosome is a strand of DNA that is encoded with genes.
In most cells, humans have 22 pairs of these chromosomes plus the two sex chromosomes (XX in females and XY in males) which make a total of 46.
Explanation:
Answer:
answer is here
Explanation:
Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from parents to offspring, DNA contains the specific instructions that make each type of living creature unique.

At which stage of the scientific process would a scientist look at experimental data from other scientists to set up a new experimental study?
a. observing
b. testing a hypothesis
c. evaluating results
d. forming a hypothesis.
Answer:
D
Explanation: press that thank you for me
The construction of a hypothesis is the stage of the scientific process that would involve a scientist looking at experimental data from other scientists in order to set up a new experimental study. Thus, the correct option is D.
What is the Scientific process?The scientific process may be defined as the complete methodology of intentionally deriving facts through the process of testing and experimentation of data.
The scientific process involves numerous steps such as formulating an observation, constructing a hypothesis, determining a prediction, conducting an experiment, and finally analyzing the outcome/results.
The analysis of the scientific data of other scientists is an approach to gathering external information based on the same topic categorized under a methodology of the scientific process.
Therefore, the construction of a hypothesis is the stage of the scientific process that would involve a scientist looking at experimental data from other scientists in order to set up a new experimental study. Thus, the correct option is D.

3.Explain how energy from the sun can eventually be used for active transport in the alimentary canal
(7 marks)
Answer:
See the answer below
Explanation:
First of all, the radiation energy from the sun is converted to chemical energy by green plants in a process known as photosynthesis. The equation of the process is represented below:
[tex]6CO_2 + 6H_20 + (radiation) -->C_6H_1_2O_6 + 6O_2[/tex]
The chemical energy is locked up as carbohydrate in the green plants. When humans or any other animal consumes green plants or any of their products, the carbohydrate is broken down through a process known as respiration. The equation of the process is as below:
[tex]C_6H_1_2O_6 + 6O_2 --> 6CO_2 + 6H_2O + energy[/tex]
The locked-up energy - usually in the form of ATP - becomes available to be used for various metabolic processes in the body, including active transport in the alimentary canal.
In some cases, humans or animals generally do not consume green plants directly. They consume organisms that consume green plants. Such humans are still able to extract some of the energy through respiration and use it for their metabolic processes.
what is sequence of steps in photosynthesis how is it different in desert plants and those in temperate regions

How will the movement of substances be altered in the phloem during spring season? Why?
Answer:
The phloem is responsible for transporting food from leaves to other parts of the plant.
The transport of pholem is bidirectional and changes the movement of particles according to the season. Generally, the transportation occurs in the direction of the source to sink but in spring season the direction is opposite that is from sink to source because the source and sink are n opposite sides. So in spring season, the stem tubers are sources and the growing leaves are sinks.
