The subatomic particle that is neutral is the Neutron. (An) electron is a negatively charged particle

According to modern atomic theory, the proton can't move from one energy level to another

With the work of the English chemist John Dalton, the current atomic theory, which has continuously undergone refining, started to blossom at the beginning of the 19th century.

The modern atomic theory holds that atoms are no longer indestructible and now contain electrons, protons, neutrons, and other sub-particles. Isotopes are variations of an element's atoms that can exist.

The concepts of atoms and how they create matter are established by current atomic theory. Atoms are composed of negatively charged electrons revolving around a core nucleus made up of electrically neutral neutrons and more massive positively charged protons.

A step in designing an experimental investigation is identifying the variables that will be controlled for all experimental groups.

The correct option to the given question is option A.

An experiment is a controlled investigation where scientists manipulate and measure specific variables. Scientists design experiments to test hypotheses and answer questions. In the design of an experiment, several steps must be followed to ensure the results are accurate and reliable.

Identifying the variables that will be controlled for all experimental groups: This is an essential step in designing an experimental investigation. Controlled variables are variables that scientists keep constant throughout the experiment so that they do not influence the dependent variable.Writing a procedure that prevents other scientists from repeating the results: Scientists usually provide a detailed description of their experimental procedures to ensure that other scientists can reproduce the results of the experiment and verify its accuracy.

Making sure that the hypothesis will be supported and not refuted: A hypothesis is a statement that scientists make that explains the relationship between the variables in an experiment. The hypothesis must be tested to determine whether it is supported or refuted.Collecting each piece of data in a different way so that there is more variety: In an experiment, data is collected to support or refute the hypothesis. Scientists should collect data in different ways to ensure that the results are reliable and accurate.

Answer:

Braided rivers have a multithreaded plan form comprising many confluences and diffluences (Miall, 1977). Braid bars and channels can be classified as a hierarchy depending upon their relative size, and three orders of braiding can be seen in proglacial rivers with constant discharge. First-order braid bars are those largest bars which are separated by major channels. First-order bars are made up of a series of smaller, second-order braid bars, which are separated by smaller channels. Third-order braid bars are contained within second-order bars. Complexity of braid pattern is, however, strongly stage dependent, with rivers losing their braided character during peak flood conditions. Braid bars, mid-channel bars, unit bars, and islands have been described in braided river systems on a range of scales ranging from meters to kilometers. All bars are subject to dissection , remobilization, and migration by the appropriate discharge magnitude and frequency (Miall, 1977, 1983).

Technological advances: Technological advances such as mechanization, fake insights, and mechanical autonomy have driven to work uprooting and changes in work prerequisites. This could make it troublesome for unions to organize laborers, as the workforce gets to be more divided and laborers are frequently more topographically scattered. For illustration, the rise of e-commerce has driven to the closure of numerous brick-and-mortar stores, coming about in work misfortunes for unionized retail specialists.

Offshoring: Offshoring alludes to the hone of moving occupations to other countries where labor costs are lower. This will make it troublesome for unions to organize specialists in businesses that are intensely influenced by offshoring, such as fabricating. For illustration, the decrease of the U.S. material industry is frequently ascribed to the offshoring of occupations to nations like China and India, where labor is cheaper.

The gig economy: The gig economy is characterized by short-term, contract, or independent work instead of changeless business. This sort of work can be troublesome to unionize, as specialists are frequently classified as autonomous contractors instead of representatives, which suggests they are not secured by conventional labor laws. For case, gig economy companies like Uber and Lyft have been at the center of legitimate debate over whether their drivers ought to be classified as workers or free temporary workers.

In general, these patterns are showing challenges to unions by making it harder to organize specialists, keep up participation, and advocate for specialist rights.

The crude birth rate is the number of live births per 1,000 of the population at the midyear census. long explanation The crude birth rate is the number of live births per 1,000 of the expected population at the midyear mark.

Given data;

CBR= 2.9%, Immigration = 1%,

CDR = 2.1%, Emigration = 1%

Now to find the Population Growth Rate use the given formula;

(CBR + Immigration) - (CDR + Emigration) = Population Growth Rate

Population Growth Rate= (CBR + Immigration) - (CDR + Emigration)

the current population of Zambia =18.92 million

now

CBR= 2.9% of 18.92 million=548680

CDR = 2.1% of 18.92 million=397320

Immigration = 1% of 18.92 million=189200

Emigration = 1% of 18.92 million=189200

now putting the values on eq.

Population Growth Rate= (CBR + Immigration) - (CDR + Emigration)

Population Growth Rate= (548680  +189200)-(397320 + 189200 )

Answer:

The oxygen produced by plants during photosynthesis is what humans and animals inhale for the blood to transport to the cells for respiration. ... The process of photosynthesis is used by plants and other photosynthetic organisms to produce energy, whereas the process of cellular respiration breaks down the energy for use.

Explanation:

Answer:

Cellular respiration is the process through which cells convert sugars into energy. To create ATP and other forms of energy to power cellular reactions, cells require fuel and an electron acceptor which drives the chemical process of turning energy into a useable form.Plants take carbon dioxide during photosynthesis and release oxygen into the atmosphere. Animals and plants take oxygen and release carbon dioxide during respiration. Thus, both plants and animals help each other in the exchange of gases in the atmosphere.

Rusting of iron and cutting an onion are both examples of chemical changes.

Rusting of iron is a chemical change because it involves a reaction between iron, oxygen from the air, and water. The iron reacts with oxygen to form iron oxide, commonly known as rust. This process is irreversible, and the chemical composition of the iron is altered during rusting.

Cutting an onion is also a chemical change because it involves the disruption of the onion's cell structure and the release of enzymes. When you cut an onion, enzymes stored within the cells are released, reacting with certain compounds to produce sulfur compounds. These compounds are responsible for the pungent smell and the tears that occur when cutting an onion. The cutting process causes a chemical transformation in the onion's composition, making it a chemical change.
