Define “isotope” using mass number, atomic number, number of protons, neutrons and electrons. (PLEASE HURRY!)
Answers
Isotopes have different mass numbers due to different number of neutrons but same atomic number due to same number of electrons and protons.
What are isotopes?
Isotopes are defined as substances having same number of protons but different number of neutrons.Number of protons is characteristic for determining position of elements in the periodic table.
Since,all isotopes have the same number of protons and hence have same position.They have similar chemical properties as they have same number of electrons.
They find applications in the field of nuclear medicine and oil and gas research . There are 2 types of isotopes : stable and unstable
Unstable isotopes are radioactive and are called as radioisotopes.Some of these isotopes are man -made and hence also called as artificial isotopes.Every element has an isotope which is either man-made or natural .
Many properties of isotopes depend on mass which is measured in atomic mass unit. The difference in actual mass and mass number is called mass defect.

You are curious about the effects of different watering schedules on your favorite fruit, strawberries. You set up plants, all the same age and size, and plant them in identical pots with the same potting soil. You water them once a week, every day, or every other day. Every day, you check the plants for strawberries, and record the number and size of the berries produced by each plant.
Answers
The complete question is as follows:
What is the independent variable in this strawberry experiment?
O the type of pots
O the number and weight of strawberries produced
the potting soil
O the water schedule
O size and age of plants
Answer:
The correct answer is - the watering schedule.
Explanation:
Independent variable is the variable or the factor which is changed or manipulated during a study or experiment to find the effect on the dependent variable.
The variable that is manipulated in this experiment is the watering schedule and the aim of the experiment is also finding the role of the effect of the watering schedule on fruit production. In this study, the watering schedule is manipulated for different pots of plants to see the effect on the production of fruit.

Explanation:
The interactions between human population dynamics and the environment have often been viewed mechanistically. This review elucidates the complexities and contextual specificities of population-environment relationships in a number of domains. It explores the ways in which demographers and other social scientists have sought to understand the relationships among a full range of population dynamics (e.g., population size, growth, density, age and sex composition, migration, urbanization, vital rates) and environmental changes. The chapter briefly reviews a number of the theories for understanding population and the environment and then proceeds to provide a state-of-the-art review of studies that have examined population dynamics and their relationship to five environmental issue areas. The review concludes by relating population-environment research to emerging work on human-environment systems.

Explain the contribution of antigenic determinant in false negative and false positive test
Answers
Answer:
The contribution of the antigenic determinant is given below:
Explanation:
Antigenic determinant or epitope is the part of the antigen that is recognized by the immune cells or antibodies such as the B- cells by binding to these cells and evokes the response in the host. The antibodies bind to the epitope segments only not to the entire antigen protein.
A false-positive test is a test where the result suggests that an individual has a specific condition but in reality not having such condition. opposite in the false-negative So, the antigenic determinant binds to the specific antibodies and shows wide significance to reduce the false-negative or false-positive.

What happends if a cell were to have an interphase 1 and 2 when doibg meiosis
Answers
First thing to remember is that interphase is a stage associated with replication of DNA, and growth. Once meiosis starts, the purpose is to produce a haploid gamete. So there is no further need of replication or growth. Hence between meiosis I and meiosis II , there is no interphase.
You have been looking at meiosis beginning with a diploid cell that has the genotype AaSs. The alleles in the haploid gametes produced by meiosis are
Answers
Answer:
AS, As, aS, as
Explanation:
Meiosis is the cell division that involves the production of daughter cells or gametes with a reduced number of chromosomes. i.e. diploid (2n) - haploid (n).
According to Gregor Mendel in his law of Segregation, the alleles of a gene will separate into gametes in such a way that only one allele will be present in each sex cell. Hence, in this diploid cell with genotype AaSs, the alleles will separate into the haploid cell in the following genotype proportion:
