Answer:27 negative
Explanation:
Define “isotope” using mass number, atomic number, number of protons, neutrons and electrons. (PLEASE HURRY!)
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.

After an organism dies, it stops taking in radioactive carbon-14 from the environment. If the carbon-14:carbon-12 ratio ( / ) in a piece of petrified wood is one sixteenth of the ratio in living matter, how old is the rock
Answer:
Age of rock= 22920 years
Explanation:
Carbon-12 isotope is a stable isotope whereas carbon-14 isotope undergoes radioactive decay. The half-life of carbon-14 isotope = 5730 years
Since the ratio of carbon-14 to carbon-12 = 1/16 : 1; number of times carbon-14 isotope decayed n
(1/2)ⁿ = 1/16
(1/2)ⁿ = (1/2)⁴
n = 4 times
time(age) for decay = n * half-life
Therefore, age of fossil = 4 * 5730 years
Age of rock = 22920 years

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.

How can two organisms have the same phenotype but different genotype
Answer:
Same phenotype but different genotype is possible due to presence of dominant allele. A person can have a dominant allele on both the homologous chromosomes (i.e. in double dose) while another person may have single dominant allele and a corresponding recessive allele
Explanation:
Answer:
Same phenotype but different genotype is possible due to presence of dominant allele.

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
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:
AS, As, aS, and as

Answer:
the heart is what makes every moving part working inside our body even though the brain is the one who tells them or gives them signals to work. the heart is what keeps them alive and if the heart takes any kind of negative damage the would not take care of everything it's supposed to.
Explanation:
Hope this helps
The body part picked is ; The Heart
An injury or disease to the heart will stop the whole body functioning and the process modeled will be distorted
The heart in the body is equivalent to the engine of a car, The heart pumps oxygen carrying blood cells into all the organs and without this oxygen carrying blood cells the whole body will stop functioning ( i.e. The organs will be dead ).
An injury or disease to the Heart will negatively affect the distribution rate of blood to all parts of the body and this will negatively affect the overall wellbeing of the body and this will also negatively affect the process been modeled as well.
Hence we can conclude that The body part picked is ; The Heart , and An injury or disease to the heart will stop the whole body functioning and the process modeled will be distorted

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.
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.

Explain the contribution of antigenic determinant in false negative and false positive test
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.
