Imagine that you wish to compare two different diets that will be fed to tadpoles raised in a lab. One diet is a meat-based fish food, and the other is the traditional diet of boiled lettuce. You want to see if the meat-based diet will be associated with an increase in the average weight of the tadpoles. In your experiment you keep all other factors, such as tadpole density per pan, temperature, pH, and the amount of food the same. The only difference between your control and experimental groups is the type of food the tadpoles receive.
Which is a good hypothesis for this tadpole experiment?
A. Tadpoles will be larger if the ph is higher.
B. Tadpole size will be unpredictable if fed a meat-based diet.
C. Tadpoles will be larger if fed a meat-based diet.
D. Tadpoles fed a meat-based diet will be bigger , but only in a tank with low numbers.
Answers
Answer:
The correct answer is - C. Tadpoles will be larger if fed a meat-based diet.
Explanation:
In this experiment, it is observed that how the change in the type of diet if meat diet is internalized how the average weight of tadpoles increase comparatively than other types of diet.
In this experiment, pH remains the same so that can there would be no effect on this by a change in pH can be established by this experiment. The dependent variable is the increase in size so the correct hypothesis will be - C.

Why can't blizzards cause secondary succession?
Answers
Secondary succession follows a major disturbance, such as a fire or a flood. The stages of secondary succession are similar to those of primary succession; however, primary succession always begins on a barren surface, whereas secondary succession begins in environments that already possess soil.
If I had to guess I would say because blizzards happen in the winter and things don't grow in the winter, therefore secondary succession cannot happen as recolonization with plants cannot happen because most plants don't grow in the winter.
Last semester I learned about succession so I'm basing my answer on the stuff I learned.

Answer:
Antibodies
Explanation:
The major compound that can form muscle tissue and protect the body from antigens is protein.
What are proteins?Muscles, bones, skin, hair, and virtually all other human organs and tissues include protein. It serves as the foundation for enzymes, which fuel numerous chemical reactions, as well as hemoglobin, which carries oxygen in your blood.The twenty-plus fundamental building blocks of protein are known as amino acids. Our bodies manufacture amino acids in one of two ways since we are unable to store them: either from scratch or by altering other amino acids. Histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine are some of the necessary amino acids that must be absorbed from the diet. Proteins are essential for carrying out complicated activities as well as for the synthesis and renewal of DNA. Proteins called enzymes to help break down food. Numerous hormones that aid in maintaining the balance of the body's constituent parts are linked to the production of proteins. Cells communicate with one another and with the outside world using surface receptors.

If an individual had an excess of ADH
in their bloodstream, they retain more
water. What do you think would
happen to the urine because of it?
Would it have more water or less
water in it? Would it be bright yellow
or pale yellow? Explain your
reasoning.
Answers
If the organism secretes an excess of ADH, urine would be less diluted and showing a bright yellow color due to salts concentration. Options: less water in it and bright yellow.
What is the ADH hormone?
Anti Diuretic Hormone is a molecule that helps kidneys to control water loss through urine.
The ADH, also known as vasopressin hormone, is released by changes in serum osmolarity or blood volume. Its function is to keep homeostasis and make kidneys conserve or keep water by concentrating urine and by reducing its volume. Through these actions, the antidiuretic hormone stimulates water reabsorption, according to the organism's needs.
When the organism secretes too much ADH, the body retains too much water, and blood volume increases.
In these cases, urine would have less water and would be bright yellow because there would be a higher concentration of salts and other waste elements.

Transverse and longitudinal waves are the two types of waves. While longitudinal waves are similar to those of sound, consisting of alternating compressions and rarefactions in a medium, transverse waves are like those on water, with their surface moving up and down.

The very long, thin DNA fibers in most chromosomes are covered with packing proteins; in eukaryotic cells, the histones are the most significant of these proteins.
Chromosomes play a critical role in organizing and compacting the DNA into a more manageable structure that allows for efficient gene regulation and gene expression.

The organism is mated with another organism that has a recessive phenotype and therefore a homozygous recessive genotype. If the offsprings of this cross all have the dominant phenotype, then the parent with an unknown genotype was homozygous for the dominant allele. If some offsprings have a recessive phenotype, then the parent must be heterozygous.

are phenols and glycosides induced or pre-existing defenses mechanisms for plants immunity ?
Answers
Phenols and glycosides are pre-existing defense mechanisms in plants' immune systems. These compounds are part of the plant's chemical defense arsenal and are present in various tissues even before any attack or infection occurs.
Phenols are secondary metabolites found in plants that have antimicrobial and antioxidant properties. They contribute to the plant's defense against pathogens by inhibiting the growth and development of microorganisms. Phenols also play a role in wound healing and lignification, which strengthen the plant's cell walls.
Glycosides are another class of secondary metabolites found in plants that have diverse functions, including defense against herbivores and pathogens. Some glycosides act as toxic compounds when ingested by herbivores, while others can inhibit the growth of microorganisms or interfere with their feeding behavior.
Both phenols and glycosides are produced by plants as part of their constitutive defenses, meaning they are present at baseline levels even in the absence of stress or attack. However, their production can be further induced or enhanced in response to specific stimuli, such as pathogen invasion or herbivore feeding.
