Answer:
cell
Explanation:
Answer:
cell
Explanation:
That is the smallest unit of life, and every living thing has at least one cell, such as unicellular living things.
Answer:
Option B)
Explanation:
A moon is a celestial body that revolves around a planet.
The others are wrong because, a planet orbits around the sun, not the sun orbiting the planet.
A meteor does not have a fixed orbit, and asteroids orbit around the star near it, in our case, the asteroid belt orbits the sun.
If my answer helped, kindly mark me as the brainliest!!
Thank You!!
Heredity refers to the process in which DNA is transmitted from parent to offspring, determining trait inheritance. DNA contains the genetic information that informs the traits of the offspring.
The key feature of living organisms that is best described as the transmission of DNA from parent to offspring is called heredity. Heredity is a fundamental biological process that refers to the passing on of genes from one generation to another. Within this process, DNA plays a crucial role as it contains the genetic material that determines the traits of an offspring. For example, you might have the same eye color as your mother because she passed on the specific sequence in her DNA that determines eye color

b. dominant autosomal
c. x-linked
d. y-linked
e. either x or y-linked
Answer:
The correct answer will be option-A
Explanation:
In the pedigree analysis, the description of a trait help shows the relation of a trait linked to a gene.
The pedigree analysis is usually used to determine the heredity of a disease in a family which has been described in the question also as
1. The trait is rare and present in both sexes- this shows that it is independent of sex chromosomes and since is rare is recessive.
2. A consanguineous mating- mating between close relative which result in autosomal recessive trait as the genes for the trait must be present on both the parents which happen only when they are closely related.
Thus, option-A is the correct answer.
Answer:
yes
Explanation:
2) What is the hypothesis?
3) Identify the independent variable versus the dependent variable.
4) What variables were held constant in this study?
5) What was the control group?
6) What data was collected during the study?
7) What this data qualitative or quantitative?
8) What was the study's conclusion?
Answer:
1. Research question is a question which is the aim of any experiment or research, in this case, the question addressed by the study is - Testing the effects of a newly developed drug to lessen the effects of the common cold.
2. Hypothesis is an explanation for the reason for any problem it does not need the evidence and completely based on logic.
The newly developed drug is able to lessen the symptoms of a common cold.
3. Independent variable is a variable manipulated or changed during the experiment:
Administration of drug or placebo (sugar pill)
4. Dependent variable is the response to the effect of the independent variable:
Number of tissues for each volunteer
5. Control group is available that remain constant throughout the study or used to compare the results:
Administration of sugar pill to 25 volunteers
6. Data is the result that the study generated -
At the end of the 7 days or one week period, symptoms of common cold disappear in both sets of volunteers who had taken either the drug or the placebo.
7. Data in this study is found is Qualitativedata as the drug is not administrated in doses.
8. Conclusion of the study is that the Placebo effect present as sugar pills relieve the common cold so This drug needs even more analysis.
