A researcher is studying the effects of caffeine on the rate of sunflower growth to determine if caffeine stimulates sunflower plants to grow taller. What is the null hypothesis for this experiment?
Answer:
A null hypothesis would be that caffeine doesn't stimulates sunflower plants to grow taller.
Explanation:
Null hypothesis: In research methods, the term "null hypothesis" is described as a type of hypothesis that proposes that there's no difference between specific characteristics of a particular data gathering process or population.
Function: The main aim of "null hypothesis" is to prove whether or not a specific test or study is supported and is separated from the researcher's own decisions and values. It is responsible for providing a way to a given study or test and is represented by H0.

1. How does your DNA differ from other peoples?how is it similar
2.How does your DNA differ from a strawberries DNA? How is it similar
Answer:
1.DNA is more than 99% similar between any two people. All the differences in how we look, feel, behave and the differences in our health are due to less than 1% difference
2.In humans each of these cells have 2 copies of the DNA, but in strawberries each of these have 8 copies of the DNA that means strawberries have 4 times as many copies of DNA as humans, making it 4 times easier to see.
Explanation:
Describe how an organism's genotypes codes for their phenotype. In your answer use the vocabulary terms: Phenotype, genotype, DNA, mRNA and protein. Please dont answer if you dont know it.
Answer:
The organism's genotype encodes their phenotype because the genotype corresponds to the characteristic that is determined by genes —formed by fragments of DNA— which are transcribed into mRNA to be translated into amino acid sequences in the synthesis of proteins, determining the morphological and functional characteristics of an organism, that is, its phenotype.
Explanation:
Genotype corresponds to the genetic information contained in the DNA, according to the sequence of nucleotides in its molecular structure. This genotype includes characteristics or polymorphisms that define the appearance and function of living beings.
Each DNA molecule constitutes a chromosome, formed by genes —DNA fragments— each of which determines specific characteristics.
When DNA is transcribed into mRNA, information is being sent that is necessary for the incorporation of amino acids into a protein that is being synthesized. The proteins, in turn, determine morphological and functional characteristics that constitute the phenotype of an individual.

The photos shown below illustrate a case of synpolydactyly, a genetic abnormality characterized by two phenotypes: partially or completely duplicated fingers or toes, and webbing between fingers or toes. The same mutations that give rise to the human phenotype also give rise to a similar phenotype in mice. In which family of genes do you think these mutations occur?
Answer:
The correct answer is - Hox gene.
Explanation:
Synpolydactyly is a joint presentation of syndactyly is the condition of the partially or completely duplicated fingers or toes and weblike development in between toes and fingers.
This takes place due to the Gene of HOX family that has mutated to rise this condition in the individual. The gene that is responsible for this genetic condition is the mutation in the D13 gene.
The correct answer is - Hox gene

Explanation:
if a blue eyed offspring is formed from black eyes parents, what type of character is the blue eye dominant or recessive? expalin with the help of a chart
Answer:
If a blue-eyed offspring forms from black-eyed parents, the blue-eyed trait must be recessive.
Explanation:
The blue-eyed trait is the recessive one because otherwise it could not come from parents with black eyes. A recessive trait is only expressed when both alleles for that trait are the same, and can only come from parents with the same trait, or heterozygotes.
In this case, both parents must be heterozygous, i.e. carriers of the recessive allele. If black eyes is B and blue eyes is b, then the genotype of the parents would be:
♂ Bb♀ BbIn a Punnett square can be seen the crossing:
Bb X Bb
Alleles B b
B BB Bb
b Bb bb
Where the offspring could be:
Bb black eyes 50%.BB black eyes 25%bb blue eyes 25%Therefore, if blue eyes is the recessive trait, as if it were the dominant trait it could not be the product of black-eyed parents.
The study of a living being is called biology.
The correct answer is recessive genes or mutation.
The character in the living organism is due to the gene present in the body. The genes are present in a pair. The single gene is known as an allele. The two alleles are as follows:-
DominantRecessiveIn this question, the parents have a black color eye but the offspring has blue color eyes. This is due to recessive gene inheritance because this gene is dormant in their parent and shows its character in this generation.
The chances of this case are 1/4 out of total.
The mutation is also the reason for the blue eyes because the abnormal change beside the population is called a mutation.
Hence, the correct answer is Recessive and mutation.

Which stage of human development might be MOST concerned with cognitive function?
middle adulthood
adolescence
early adulthood
advanced adulthood
Answer:
Preschoolers, ages three to six, should be at the "preoperational" stage of Piaget's cognitive development theory, meaning they are using their imagery and memory skills. They should be conditioned to learning and memorizing, and their view of the world is normally very self-centered.
Explanation:
so early adulthood think so
The stage of human development that might be most concerned with cognitive function is advanced adulthood. The correct option is D.
What are cognitive functions?Cognitive functions are the psychological functions that are the mental processes that are done to express feelings and actions. They are eight types of cognitive functions.
In advanced adulthood, humans use most of the cognitive functions of the body.
Thus, the correct option is D, advanced adulthood in regard to the stage of human development.

Propose an explanation as to
why beta cells would have a
greater concentration of rough
endoplasmic reticulum and
ribosomes than some other cell
types.
Answer:
The intense and constant activity of insulin synthesis explains why pancreatic beta cells possess more rough endoplasmic reticulum and ribosomes than other cells.
Explanation:
Both ribosomes and the rough endoplasmic reticulum are necessary for protein synthesis to occur. In cells whose function is to produce substances, such as glands, the content of these cellular structures is higher in order to fulfill their function.
The pancreatic beta cells, located in the islets of Langerhans, have the function of synthesizing insulin, an endocrine hormone in charge of regulating the glucose content in the blood. Because the beta cells constantly produce insulin, their content of rugged endoplasmic reticulum and ribosomes is high, in order to satisfy the demand for this hormone in the body.

Answer:A
Explanation:
Organisms are classify on the basis of kingdoms Bacteria, Protista, Fungi, Plantae, Animalia, Phylum. Therefore, option (A) is correct.
How do we classify organisms?Organisms can be classified according to any number of criteria, including overall similarities, colors, ecological functions, etc. However, it is generally agreed that the most useful way for scientists to organize biological diversity is to group organisms according to shared evolutionary history.
It is divided into phyla or divisions, which are further subdivided into classes. Further divisions include order, family, genus and species, in that order. Thus, species is the basic unit of classification.
Organisms are usually grouped together based on their unique characteristics. The classification of an organism often provides useful information about its evolutionary history and which other organisms are related to it.
