Answer:
Electron
Explanation:
I got a 100 on my test trust me its Electron
The subatomic particles which determine an element's chemical properties are electrons. Electrons are present in the specific orbitals in an atom. Thus, the correct option is B.
What is an electron?An electron is a negatively charged subatomic particle. An electron can be either bound to an atom or in free state. An electron which is bound to an atom in an orbital is one of the three types of particles present within the atom. Other primary subatomic particles which are present in an atom include protons and neutrons. Together, electrons, protons and neutrons form the nucleus of an atom.
Electrons were discovered by J.J. Thomson in 1897. The mass of an electron is 9.109×10⁻³¹ kilograms and the charge is −1.602176634×10⁻¹⁹ C.
Therefore, the correct option is B.

1. Scientific question: Can detergent affect flower growth?
2. IV: The soap used in the study
3. DV: Flower growth
Explanation:
A scientific question is a well-sustained question about a given phenomenon of the real world which can be answered by experimental and/or observational procedures. A good scientific question must be testable and lead to falsifiable hypotheses. The dependent variable is the variable that is being measured in the experiment, (i.e. it is being affected by the experimental procedure). On the other hand, the independent variable is the variable that isn't changed by the other variables that are being measured in the experiment.

3. Which term describes an organism with no hard skeleton? *
a)Endoskeleton
b)Hydrostatic
C) Exoskeleton
Answers
Answer:
B) Hydostatic
Explanation:
Hydrostatic skeletons are found in invertebrate organisms, it means the skeleton is fluid filled, these are common in simple organisms. Endoskeletons are in vertebra animals, humans have an endoskeleton. Exoskeletons are in insects, which are invertebrates but the bone-like material is hard. I would chose Hydrostatic since it is filled with a liquid.

a. No health issues arise without an interaction between genetic and environmental factors.
b. Health issues related to toxic environments can occur independent of genetic inheritance.
c. Health issues, such as depression, are related solely to environmental factors.
d. There is no known connection between environmental factors and health.
Answers
Answer:
Health issues related to toxic environments can occur independent of genetic inheritance.
Explanation:
The statement which is true about the relationship between genetic and environmental factors relating to health is, that health issues related to toxic environments can occur independently of genetic inheritance.
What do you mean by Genetic inheritance?Genetic inheritance may be defined as a principle that explains the process of characteristics that are passed from one generation to the next.
The toxic environment is responsible for the number of health diseases among organisms. These diseases may reflect the pattern of genetic inheritance as well, but it is not significantly accepted or analyzed.
Genetic inheritance depends on the physiological characteristics of involving parents.
Therefore, the statement which is true about the relationship between genetic and environmental factors relating to health is, that health issues related to toxic environments can occur independently of genetic inheritance.

C. The absence of oxygen
D. With little available oxygen
Answers
Answer:
A. How your body uses oxygen
Explanation:
Aerobic literally means "with oxygen", and refers to the use of oxygen in muscles' energy-generating process. Aerobic exercise includes any type of exercise, typically those performed at moderate levels of intensity for extended periods of time, that maintains an increased heart rate.
The correct answer to your question "What does aerobic refer to?" is: A. How your body uses oxygen.
Aerobic reaction can be defined as a biological and chemical reaction that occurs in the presence of oxygen.
On the other hand, an anaerobic reaction refers to a biological and chemical reaction that doesn't require oxygen such as glycolysis.
Some examples of an aerobic reaction include the following:

Answers
Explanation:
What you need to understand first, is the digestive system, after that, you'll probably be able to understand not only sugar, but other components of your food too.
It all starts at your mouth, you are going to do a lot of the job for the food to get to your stomach by chewing it. After it gets to your stomach, the digestion will do its job as the pH there is less than 7. After this process, the food is going to your intestine, and then, it's right here, that the sugar/carbohydrates you ate are going to get into your blood. After this, sugar is going to be used to create energy for your cells and body to work properly, with that, sugar is consumed and you can start the process all over again.
Where does the H+ come from that makes ATP synthase work?
Answers
Answer:
Electron Transport Chain
Explanation:
Gizmos Cell Respiration
The H+ that's vital in making ATP synthase work comes from the electron transport chain.
The electron transport chain can be found in the mitochondria. It is a series of protein complexes that are able to transfer electrons from the electron donors to the electron acceptors.
It should be noted that the transfer of the electrons from the electron donors to the electron acceptors is done through the redox reactions. This is illustrated in the H+ that made the ATP synthase work.

(5) a) What is pathogen and write about different types of pathogens? b) Give name of the diseases of each pathogen. c) Do the pathogens enter directly into the body? How? d) What is incubation period?
Answers
Answer:
Microorganisms which causes diseases is known as pathogen.
Explanation:
PATHOGEN -: Pathogens are agents that live in a host and are responsible for causing infections or diseases in that host, such as a human being. Microorganisms such as bacteria , viruses , fungi or protozoa, or other organisms such as parasites, worms and even contagious proteins such as prions, may be pathogens.
Viruses: Viruses are micro-organisms that are composed of nucleic acid and covered by a protein sheet. A lipid (fatty) outer layer is also present in some viruses. Enveloped viruses are called these. Non-enveloped viruses are considered those that do not have this lipid outer layer. Only inside their host's living cells are viruses able to replicate. EXAMPLE -: Influenza (influenza A and B viruses) and the common cold (rhinovirus) are examples of infections caused by viruses.
Bacteria: These are microorganisms which have a nucleus containing DNA surrounded by a cell wall or membrane. Among bacteria, the composition of the cell wall differs. If they are able to access food and nutrients, they have a more complex structure than viruses and can multiply beyond the host. EXAMPLE -: Foodborne diseases can be caused by bacteria such as Salmonella enterica and Escherichia coli, while Staphylococcus aureus can cause skin infections.
Fungi: Fungi are single-celled or multicelled species that can live outside a host. They consume food and nutrients created after digestive enzymes have been secreted into their atmosphere. example-: The foot of the athlete (Trichophyton mentagrophytes) and yeast infections (Candida albicans) are examples of infections caused by fungi.
Prions: These are infectious agents made up entirely of proteins and capable of transferring to other prion proteins their infectious properties. EXAMPLE -: Extreme infectious diseases such as bovine spongiform encephalopathy (mad cow disease) and variant Creutzfeldt-Jakob disease (vCJD) can be caused by prions.
Protozoa: Protozoa are single-celled organisms that display habits that are similar to animals, such as the ability to travel through water, and are capable of harvesting other microorganisms. They are able to live outside the human host, but when they enter the human host and spread, causing infections and diseases, they may also be parasitic in nature. EXAMPLE -: Malaria and giardia include common infections
Yes , pathogen enter into the body directly -: Direct contact infections spread when, through direct physical contact with blood or body fluids, disease-causing microorganisms move from the infected person to the healthy person. Touching, kissing, sexual contact, contact with oral secretions, or contact with bodily lesions are examples of direct contact.INCUBATION PERIOD OF A PATHOGEN -:The period of incubation is the interval between exposure to a pathogenic organism, a drug, or radiation, and when the first signs and symptoms are evident.
