What is the independent and dependent variable in this:
"Sandy heard that plants compete for space. She decided to test this idea. She bought a mixture of flower seeds and some potting soil. Into each of 4 plastic cups, she put the same amount of soil. In the first cup she planted 2 seeds, in the second cup she planted 4 seeds, in the third cup 8 seeds, and in the fourth cup 16 seeds. After 25 days she checked to see how many plants had grown and their height."
Answer:
The correct answer will be- the number of seeds in cups.
Explanation:
The scientific experiments involve the parameters which directly controls and help determine the hypothesis. These parameters are known as the variables which could be changed or kept constant.
The variables which could be changed or manipulated by the researcher or can get a change on its own like time are known as the independent variables. The variables which depend on the independent variables and are to be studied are known as the dependent variable.
In the given question, sandy studied the growth pattern and height of the plant which are considered dependent variables but they changed the number of seeds in the cups and thus they will be considered as the independent variables.
Thus, the number of seeds in the experiment represents the independent variables.
he sun’s energy is most useful to humans after it is converted to _____. heat nuclear energy light radiation
Final answer:
The sun's energy is most effectively utilized by humans in the form of heat, which is used in various ways, such as heating buildings and powering appliances.
Explanation:
The sun's energy is most useful to humans after it is converted to heat. While the sun does convert mass into energy through nuclear fusion, the vast majority of useful energy we harness from the sun on Earth is in the form of heat and light. For example, solar panels convert sunlight into electricity, which is then used to heat buildings, power appliances, and more. Moreover, the sun's energy is essential for life on Earth, as it allows for photosynthesis in plants, which is the foundation of most food chains. Lastly, the thermal energy from the sun also drives weather patterns and climate.

What information does RNA code for?
A) DNA replication
B) protein synthesis
C) polypeptide building
D) gene production
Answer:
B) protein synthesis
Explanation:
An RNA codes for protein synthesis. A triplet of nucleotides/bases in RNA helps in adding an amino acid into the protein strand. This triplet of nucleotides is knwon as codon and helps in adding amino acid which is specific to it. For example, AUG triplet codes for methionine while UGG codes for tryptophan. The amino acids get added in protein strand unless a stop codon is reached. Triplets UAA, UAG & UGA are stop codons. Here it may be noted that initially a polypeptide chain is synthesized by RNA but the ultimate goal of making that polypeptide chain is protein synthesis.
Answer: The correct answer is -
B) protein synthesis.
Explanation:
RNA (ribonucleic acid) contains codon (a sequence of three nucleotides that code for particular amino acid) sequences that help in the process of protien synthesis (translation).
The genetic information is transferred particularly from mRNA to proteins at the site called ribosomes.
tRNA (transfer RNA) molecule arrives at ribosome with specific amino acid according to the codon present in the mRNA.
In this way, a long chain of amino acids is assembled to form proteins.
Thus, option B) is the right answer.

What is condensation
Condensation is the phase change from gas to liquid. You can see condensation in the real world if you have a very cold drink. A bottle of water filled with ice will attract water vapor from the air, and it will condensate around the bottle because the temperature is lower, which facilitates the phase change. The outside of the bottle will contain a bunch of water droplets.
Hope this helps!!
Condensation is apart of the water cycle and it is when water vapor turns into a liquid for example when it’s humid out and you leave your water cup out in the sun it will form water droplets on the cup and that is an example of condensation

Answer:
In South Florida, the non-native Burmese pythons have developed a breeding population, and are one of the most issue creating invasive species in the Everglades National Park. With the local wildlife, the pythons compete for food that comprises birds, mammals, and other reptiles.
The declining of many mammals in the National Park is being associated with the growth of Burmese pythons. Of which the major impact has taken place in the remote southernmost parts of Everglades National Park, where pythons have got established a long time ago. It has been found that the populations of opossums, raccoons, and bobcats have declined by more than 90 percent in the region, while cottontail rabbits, marsh rabbits, and foxes have got vanished.

The Axolotl, or the Ambystoma mexicanum, is located in the class amphibia and in the family of Ambystomatidae. They are a critically endangered species that resides in Mexico. More specifically, the walking fish is native only to Lake Xochimilco and Lake Chalco in central Mexico. These unique fish have many attributes that makes it different from other amphibians and fish found in lakes.
Axolotls are 9 inch "walking fish" that have the amazing ability to regenerate limbs. They can regenerate any lost limb, including their head. This salamander has a soft bodies with small "horns" sprouting from the sides of their head. These horns are actually gills, meaning that instead of having their gills located inside of their pharynx the frills are set on the sides of their head.
The spots commonly found on an axolotl are not unusual, it's part of an extremely advanced system called the lateral line system. This system consists of electroreceptive ampullary organs and mechanoreceptive neuromasts organized into lines across the creature's body. This system is connected to the nervous system, and it allows the axolotl to sense movement and vibrations in the water.

Which statements describe traits of nonvascular plants? Check all that apply.
They use roots and stems for nutrient transport.
They are found close to the ground.
They have seeds for reproduction.
They produce flowers.
They use diffusion for nutrient transport.
Answer: They are found close to the ground.
They use diffusion for nutrient transport.
Explanation:
Non- vascular plants are the plants which do not posses a vascular system. They do not have vascular tissues called as xylem and phloem. Examples of non-vascular plants include bryophytes- liverworts, mosses and hornworts. They have simple tissues for the transport of water.
Among the options the following traits of non- vascular plants are:
They are found close to the ground.: The non-vascular plants lack vascular tissues, true roots stems and leaves. They directly absorb water and minerals directly from the soil. They grow as clumps and mats over the grounds.
They use diffusion for nutrient transport.: As the non-vascular plants lack vascular tissues they directly absorb the water and nutrients from the soil. As a result of this these plants are small and are limited to moist habitats. The transport of these nutrients takes place from cell to cell by diffusion and osmosis process.

Plants add water to the atmosphere through
Plants add water to the atmosphere through transpiration. Transpiration is the process of water moving through plants and evaporating, becoming water vapor. This water vapor is released into the atmosphere.
Answer:
Transpiration
Explanation:
Vegetal transpiration corresponds to the process of water dispensing in the form of steam, given to the environment through a unidirectional sense, that is, of the water rising from the root region towards the leaves, and from these to the atmosphere. Therefore, we can conclude that it is through plant transpiration that plants add water to the atmosphere.
Which trend do the data in the maps support ??
i think that the land is warmer
Answer: In the given maps, there shows the temperature anomalies in both land as well as sea surface. In the sea surface, the temperature anomaly ranges from -5°C to 5°C which is comparatively lesser than the land temperature i.e -12°C to 12°C.
Thus from the provided data in the map, we can conclude that the average temperature in the land surface is more than the sea surface because the sea surface has the capacity to reflect back heat to the atmosphere but land surface cannot reflect much of it, thereby becomes more warmer as it absorbs most of the incoming solar radiations.
Which of the following would produce a silent mutation?
A. The deletion of a single base.
B. The replacement of a single base, producing a stop codon.
C. The replacement of a single base, producing the same amino acid.
D. The insertion of a single base.
Answer:
C
Explanation:
A silent mutation is a mutation that does not have an observable change or effect on the organism bearing it. If a base in a DNA sequence changes but the new codon codes for the same amino acid (remember amino acids translation have redundancies), then they will be no observable effect. The most lethal kind of mutation is deletion and insertion because they result in a frameshift mutation.
Answer:
C
Explanation:
a silent mutation is not one that can be seen or abserved in the phenotype
