If conducted accurately identical investigations should produce similar results. Sometimes, errors like measurement errors, can
cause differences in results
Sandra and Jeremy are neighbors who tested different brands of seeds in their gardens for six weeks. They grew identical gardens
in their yards and recorded results. Each of them tried three brands of pea plant seeds and recorded the plants' heights at the end
of each week. They discovered Jeremy's plants were much taller on average than Sandra's plants every week.
Which statement describes a measurement error that may have caused such a significant difference in their results?
Sandra recorded her measurements in centimeters, while Jeremy recorded
his measurements in inches.
They both took measurements on Fridays, but Sandra took hers at 4:00 PM
and Jeremy took his at 5:00 PM
Sandra used a measuring tape to collect data, while Jeremy used a wooden
tuler to take his measurements

D
Sandra measured her plants from the ground while Jeremy measured his
plants from the ends of their roots
Answer:
D Sandra measured her plants from the ground, while Jeremy measured his plants from the ends of their roots.
Explanation:
The statement that describes a measurement error is Sandra measured her plants from the ground while Jeremy measured his plants from the ends of their roots.
What do you mean by Seeds?Seeds may be defined as the unit of reproduction of a flowering plant, capable of developing into another such plant.
Three brands of pea plants are grown in the field of equal dimension, still, there may be a difference in their height that must be identified. This is surely due to a measurement mistake.
Therefore, it is well described above.

The energy used in photosynthesis come from what??
Answer:
chloroplasts.
Explanation:
Chloroplast
Chloroplasts are organelles that conduct photosynthesis, where the photosynthetic pigment chlorophyll captures the energy from sunlight, converts it, and stores it in the energy-storage molecules ATP and NADPH while freeing oxygen from water in plant and algal cells. They then use the ATP and NADPH to make organic molecules from carbon dioxide in a process known as the Calvin cycle. Chloroplasts carry out a number of other functions, including fatty acid synthesis, much amino acid synthesis, and the immune response in plants. The number of chloroplasts per cell varies from one, in unicellular algae, up to 100 in plants like Arabidopsis and wheat.

Dwayne is making a cladogram using a diagonal line. He should place the least primitive organism in E. The correct option is A.
What is a cladogram?Diagrams are called cladograms to show the relationships between various taxonomic groups known as "clades." Cladograms reconstruct the taxa's evolutionary history (phylogeny) by showing these relationships. Phylogeny and trees are other names for cladograms.
Using the term "cladogram" emphasizes to some biologists that the diagram represents a hypothesis about the true evolutionary history of a group, whereas "phylogenies" represent true evolutionary history.
A cladogram's root, clades, and nodes are its most important components. The root is the first ancestor shared by all groups that branched off from it.
Therefore, the correct option is A, E.

Help guys I need this ASAP
Answer:
Probably A
Explanation:
The trp operon encodes the genes required to synthesize tryptophan. This operon is regulated by a feedback loop in which tryptophan binds to a transcriptional regulator leading to a change in gene expression from the operon. This is most likely an example of__________. a. inducible gene expression b. repressible gene expression c. constitutive gene expression d. post-translational regulation of gene expression
Answer:
The correct answer is option b. "repressible gene expression".
Explanation:
The trp operon is a classic example of a repressible gene expression. The trp operon controls the biosynthesis of tryptophan from an initial precursor by encoding five genes that translate to three enzymes. These enzymes act as regulators and tryptophan itself acts as the final regulator. Tryptophan inhibits its own production when it binds to the transcription regulator, therefore it is an example of a repressible gene expression.
In rats, gene B produces black coat color if the genotype is B–, but black pigment is not produced if the genotype is bb. At an independent locus, gene D produces yellow pigment if the genotype is D–, but no pigment is produced when the genotype is dd. Production of both pigments results in brown coat color. If neither pigment is produced, coat color is cream. Determine the genotypes of parents of litters with the following phenotype distributions. Part A 4 brown, 4 black, 4 yellow, 4 cream
Answer:
Bbdd and bbDd
Explanation:
From the illustration:
B_dd - black color
bbD_ - yellow color
B_D_ - brown color
bbdd - cream color
In order to produce litters in the ratio 4 brown, 4 black, 4 yellow, and 4 cream; the genotypes of the parents must be Bbdd and bbDd. The cross between the two parents would be such that:
Bbdd x bbDd
4 BbDd - brown color
4 bbDd - yellow color
4 Bbdd - black color
4 bbdd - cream color
See the attached image for the Punnet's square analysis of the cross.

What roles do species play in ecosystems?
There are some species in every ecosystem that are necessary for the other species in the system to survive. The ecosystem may not be able to continue functioning without the keystone species, which could be a small plant or a large predator.
What are keystone species ?
Scientists may argue over which organisms or plants in a given ecosystem should be called a keystone species because a keystone species does not have a formal name. The idea, according to some wildlife scientists, oversimplifies the role of a single animal or plant in intricate food webs and habitats. On the other hand, referring to a specific plant or animal as a "keystone species" in an ecosystem is one way to educate the general public about how crucial one species can be to the continued existence of numerous others.There are three sorts of cornerstone species referred to by numerous researchers: mutualists, ecosystem engineers, and predatorsThe "keystone" is regarded as one of the most crucial components in any community or arrangement. An organism that contributes to the stability of the system is known as a keystone species in any kind of ecosystem, including marine ecosystems. Ecosystems would look very different without its keystone species. If their keystone species vanished, some ecosystems might not be able to adjust to changes in the environment. That could result in the ecosystem's demise or it could allow an invasive species to take control and significantly alter the ecosystem's course.To know more about keystone species check this:

Which of the following is NOT one of the potential mechanisms allowing kin recognition among animals? Group of answer choices kin-differential spatial association, so that kin are reliably found in a given place phenotype matching, whereby kin are identified through comparison of their phenotypic attributes with those learned from reliable kin, including oneself kin-differential familiarization, whereb social familiars are treated as relatives. kin-branding, whereby all individuals are labeled actively by each other at birth so that kin can be discriminated from nonkin. genetic similarity detection, whereby phenotypic labels are correlated with one's underlying genotype, allowing for kin discrimination based on that.
Answer:
The correct answer is "kin-branding, whereby all individuals are labeled actively by each other at birth so that kin can be discriminated from nonkin".
Explanation:
Kin recognition, also known as kin detection, is an ability developed by some animals to detect organisms that are genetic related and discriminate among other animals that are not (nonkin). There are some mechanisms that animals use for kin recognition, however labeling actively each other is not one of them. In most cases, animals use kin recognition based on pheromonal cues.

The body works to maintain homeostasis in response to what conditions?
Answer:
so the body works to maintain homeostasis in response to internal or external conditions
Explanation:
Homeostasis is the process of maintaining a stable internal conditions, Homeostasis keeps internal conditions just right for cell function.
Its like if your hot your body with sweat to cool you down
OR
when your cold you shiver which contracts the things inside of your body so your body contains more heat rather than releasing it
An example of Homeostasis in response to internal conditions is:
when your body produces too much glucose, your body releases insulin to bring the level of glucose down
and when there isnt enough glucose your body releases glucagon to bring up the level of glucose to stable your blood sugar
Homeostasis has been the bodily process that is involved in maintaining the environment of the body. The body works to maintain homeostasis in response to internal and external changes.
What is homeostasis?Homeostasis has been defined as the steady internal environment for the maintenance of physiological processes. This involves the optimization of the variables and carious functions so that equilibrium can be achieved.
The factors involved in homeostasis are pH levels, temperature, glucose, etc. It has been the response of the cell towards the external environment so as to maintain balance. The homeostatic range is important for the proper functioning of the body.
The changes in the internal and external environment affect homeostasis as an increase in temperature in summer leads to sweating and a decrease in temperature in winter leads to shivering. It uses the feedback mechanism to maintain equilibrium.
Therefore, the process of homeostasis is in accordance with internal and external changes.
