Pablo and Johanna have to do a yearlong study for their biology course. After some discussion, they decide to try comparing their dogs and the diet that they feed them. Each has a dog from the pound, and both dogs are less than one year old. Pablo feeds his shepherd-mix dog a special diet of wet and dry foods from the local vet, while Johanna uses generic dry kibble from the supermarket for her bulldog. They want to see which diet results in bigger, healthier, faster-growing dogs. The reason the instructor gives them will include the fact that they have too many ______
Answer:
The correct answer is - variables that they didn't control and not enough replicates
Explanation:
In this particular case, Pablo and Johanna using too many variables in their experiment or research, All the variables used, are not controlled and with time these variables can not be replicated again on experiment groups.

With over 600 muscles in the body we are able to do an array of motions. What is the difference between what big muscles, like the four in the quadriceps, can do and what those like the thirty in our hands can do?
The functions of each muscle depend on its location and ability to perform specific work. For example, the masseter muscle is the strongest muscle in humans which is present in the jaw.
What is the significance of muscles?The significance of muscle is understood by the fact that these structures are linked to bones, internal organs, and blood vessels. These components are responsible for movement by their contractions.
According to the context of this question, the muscles in the shoulder region are the four rotator cuffs which significantly include the supraspinatus, infraspinatus, teres minor, and subscapularis. The four muscles in the quadriceps have to perform a different function which includes heavy weightlifting, so, they have to strongest enough.
While the thirty muscles present in the hand can do numerous functions with different levels of intensity. These muscles are not too strong as compared to masseter but are superior.
Therefore, the functions of each muscle depend on its location and ability to perform specific work.

Explanation:
in prokaryotes certain proteins act to regulate genes by binding dna, what could be the effect of these binding proteins?
Answer:
This question lacks options, the options are:
A. They may act to turn on gene transcription.
B. They may act to turn off gene transcription.
C. They may become added to DNA, and then be transcribed.
D. They may remove a gene from DNA.
E. They may alter the nucleotide sequence in a gene.
Options A and B are the answers.
Explanation:
Prokaryotes regulate gene expression at the transcriptional level. Gene expression is the process whereby living organisms synthesize useful products such as protein from a gene. Prokaryotes such as bacteria control the expression of their genes via proteins that bind to DNA called REGULATORY PROTEINS.
These regulatory proteins also known as TRANSCRIPTION FACTORS, act to regulate genes by binding DNA. The binding of DNA either prevents or promote the binding of RNA polymerase in order for transcription to occur.
- Regulatory proteins which may act to inhibit transcription of DNA by turning off gene are called REPRESSORS.
- Regulatory proteins which may act to promote transcription of DNA by turning on gene are called ACTIVATORS.

Which best describes tA male cardinal's red color is an example of a trait affected by natural selection. The females of the species choose mates based on the vibrant colors of the males' feathers. If females begin using different criteria than feather color when they choose mates, what would most likely happen to the color of the male cardinals over time? he fossil record?
Question:
A male cardinal's red color is an example of a trait affected by natural selection. The females of the species choose mates based on the vibrant colors of the males' feathers. If females begin using different criteria than feather color when they choose mates, what would most likely happen to the color of the male cardinals over time?
Answer:
Feather color loses importance in sexual selection and becomes disadvantageous for males. There is a decrease in red color variation among males.
Explanation:
In cardinal species, females choose males to mate according to their vibrant red color. The redder the male is, the better genetic charge it has, and the better choice for mating it becomes.
Red feather color is a trait that reflects the genetic quality of males. So individuals with the most vibrant red color express better capabilities of finding food, competing for resources, competing for males, among others, are the best option to mate and to ensure successful offspring.
The brightest or most vibrant males are in red, the better chances they have to mate and pass their genes to the following generations. So the organism spends energy and resources to produce more vibrant colors to enhance mating chances.
However, if females begin using different criteria than feather color when they choose mates, color production stops making sense. What is even more, it becomes more disadvantageous for males because females do not use color for their choices, males spend energy when producing it, and the redder the males are, the more chances to be predated they have. So basically, males´ feather color loses importance. The selection pressure in males turns to the evolution of another trait. The shade variation of red feathers will decrease over time.
Why do organisms that fertilise internally tend to produce less eggs?
Answer:
Explanation: Internal fertilization has the advantage of protecting the fertilized egg from dehydration on land. The embryo is isolated within the female, which limits predation on the young. ... Even though fewer offspring are produced through this method, their survival rate is higher than that for external fertilization.

In cherry tomatoes, red color (R) is dominant to yellow color (r). If two heterozygous plants are crossed, what percentage of the offspring will be yellow?
Answer:
50
Explanation:
If you cross two heterozygous tomato plants, you get four base genotypes of (Respectively,) RR, Rr, Rr, and rr. That makes your percentage A. 50%.
Explain h0mozygous and heter0zygous?If a dominant red fruit (RR) plant is crossed with a recessive over yellow fruit (rr), then the phenotype will be red fruit and the genotype Rr. It is a case of complete dominance.
In diploid organisms (2n), an individual is homo-zygous when it carries two copies of the same gene variant (i.e., the same allele).
Moreover, an individual is heter0zygous when it carries two different alleles for the same gene locus.
In complete dominance, the dominant allele completely masks the expression of the recessive allele in heter0zygous individuals.
