1. A study is being done to test the effects of habitat space on the size of fish populations. Different sized aquariums are set up with six goldfish in each one. Over a period of six months, the fish are fed the same type and amount of food. The aquariums are equally maintained and cleaned throughout the experiment. The temperature of the water is kept constant. At the end of the experiment the number of surviving fish are surveyed. a. Independent Variable: b. Dependent Variable: c. Controlled Variables/Constants: d. Experimental Controls/Control Groups:
Answer:
a. Independent Variable: different sized aquariums
b. Dependent Variable: number of surviving fish
c. Controlled Variables/Constants: amount and type of food, aquarium maintenance and water temperature
d. Experimental Controls/Control Groups: none
Explanation:
In an experiment, the dependent variable is the condition that is being measured or tested in the experimental procedure, while the independent variable isn't changed and serves to measure the outcome of the dependent variable. Moreover, the constant variables are those conditions that stay the same in the experiment. As observed in the case above described, an experiment usually has multiple constant variables. Finally, a control group is composed of individuals/research subjects who do not receive the experimental treatment, and therefore they can be used to compare the outcomes observed in the experimental groups.

the ocean
Ocean Salinity Increases
Ocean Salinity Decreases
Answer:
1. in ocean salinity increases
2. ocean salinity decreases
3.ocean salinity increases
4. ocean salinity decreases.
Explanation:
The salinity of the ocean is increased by the evaporation of ocean water and the formation of sea ice.
The salinity of the ocean is decreased by the melting of sea ice and entering a freshwater stream into the sea.
What is Ocean Salinity?Ocean salinity may be defined as the presence of the concentration of salts in the ocean. A Hydrometer is an instrument that determines the salinity of the ocean.
The addition of freshwater streams into the ocean and melting of ice reduce its salinity, as it makes the sea water less dense.
On contrary, the left two processes are opposite to above and thus are responsible for increasing the salinity of the ocean.
Therefore, it is well described above.

What needs to change so that only the green solutes diffuse across the membrane?
What need to be changed is ; The use of selectively/semi-permeable membrane
To selectively allow the passage ( diffusion ) of a certain type of solute through a membrane in a solution, we should make use of a selectively permeable membrane which allows only the passage of a certain type of solute contained in the solution ( like the green solutes ).
The use of permeable membrane in a solution is to selectively allow flow of solutes or solvent from a region of lower concentration to a region of higher concentration.
Hence we can conclude that what needs to be change is The use of selectively/semi-permeable membrane will allow only the green solutes to diffuse across.

Name two homologous structures in vertebrates. Why are they so called ? How do such organs help in understanding an evolutionary relationship ?
Please help me with this, i'll reward brainliest.
Answer:
1) homologous structures in vertebrates - Limbs of birds, mammals, amphibians and reptiles. 2) They are so called since they have similar basic structural plan, but appear different externally and perform different function. However they have evolved from a common ancestor. 3) The homologous characteristics indicate common ancestory.
Explanation:
I just hope this helps!
➜ Two homologous structures in vertebrates are:
Limbs of birds and reptiles.Limbs of reptiles and amphibians.These are so called because the organ have similar structure to perform different functions in various vertebrates.
The homologous characteristics of such organs indicate common ancestory. Thus these exist an evolutionary relationship.
Many farmers and gardeners compost their plant and animal waste. The living material naturally decays in compost bins, forming a dirt-like substance that’s rich in nutrients. The next season, farmers use this substance as a natural fertilizer for their crops. A biology student has grown tomato plants for several years. Until now, he used an artificial fertilizer formulated for tomato plants. This fertilizer caused his plants to grow faster and taller than they grew in unfertilized soil. The student wants to know whether using natural compost will cause his tomato plants to grow faster and taller than his artificial fertilizer. Answer the following questions to plan an investigation using the steps of the scientific method and help the student find the answer to his question. Construct at least two possible hypothesis for the students experiment
Answer:The student's observations before he starts his experiment are that his tomato plants grew faster and taller with his artificial fertilizer rather than without any fertilizer at all.

How come you don't see the carotene pigments?
HELP PLEASE!!!!!!!!!
Answer: Carotenoids are pigments in plants, algae, and photosynthetic bacteria. These pigments produce the bright yellow, red, and orange colors in plants, vegetables, and fruits.Carotenoids act as a type of antioxidant for humans.There are more than 600 different types of carotenoids. Some can be converted into vitamin A when released into the body. A few of the most common carotenoids include: 1. alpha carotene 2. beta carotene 3. beta cryptoxanthin 4. lutein 5. zeaxanthin 6.lycopene

Antigens are foreign proteins that invade the systems of organisms. Vaccines function by stimulating an organism's immune system to develop antibodies against a particular antigen. Developing a vaccine involves producing an antigen that can be introduced into the organism being vaccinated and which will trigger an immune response without causing the disease associated with the antigen. Certain strains of bacteria can be used to produce antigens used in vaccines. Which of the following best explains how bacteria can be genetically engineered to produce a desired antigen? A. The gene coding for the antigen can be inserted into plasmids that can be used to transform the bacteria. B. The bacteria need to be exposed to the antigen so they can produce the antibodies. C. The DNA of the antigen has to be transcribed in order for the mRNA produced to be inserted into the bacteria. D. The mRNA of the antigen has to be translated in order for the protein to be inserted into the bacteria.
Answer:
A. The gene coding for the antigen can be inserted into plasmids that can be used to transform the bacteria.
Explanation:
Genetic engineering is the process of manipulating an organim's genome in order to yield a desirable result. According to this question, a vaccine is to be created using an antigen that will trigger an immune response against the particular disease in the involved organism.
However, the antigens needs to be produced by genetically engineering/modifying bacteria. To do this, the gene coding for the antigen can be inserted into plasmids, an extra-chromosomal DNA, that can be used to transform the bacteria. In other words, the plasmid + antigen gene, which represents the recombinant DNA will confer upon the transformed bacteria the ability to produce the antigen.
Answer:
The gene coding for the antigen can be inserted into plasmids that can be used to transform the bacteria.
What is the purpose of a control in this experiment?
Question 9 options:
The control is the tube that only has milk in it.
The control is the one tube that we know will show milk digestion.
The control is the one tube that we know will not show milk digestion.
The control is the only one the scientist changes.
Answer:
I can't definitively answer this because I don't know the experiment, but I can help.
Explanation:
The "control group" of an experiment is like a dry simulation, where there is no variables changed across all the different trials you do. This is different from a dependent variable or an independent variable. Using your newfound knowledge of what a control group is you can automatically cross off the last option.
Since I cannot see what your experiment was I can't give you which of the top 3 answers it is however. You need to look at which one has no change.
If I were to blindly guess I would say the top option seems like the most likely answer.
what are notes for the nervous system section in edge?
plz tell me the truth
Answer:
The Brain
In the brain, the cerebrum is the largest part; it controls voluntary movement (actions you choose to do), sensory processing (vision, hearing, smell, taste, touch), speech, memory, intelligence, and emotion. The cerebrum allows you to move your muscles and know what to do when you're playing. Next, the cerebellum helps regulate motor control, coordination, and balance. The cerebellum lets you play your favorite sport since it detects shifts in balance when you're moving then sends signals to your body so it can adjust and move smoothly. The brain stem has several necessary functions: however, the medulla oblongata, which connects the brain and spinal cord, best helps you play sports since it executes a critical role in regulating involuntary functions, including respiration (breathing), heart rate, blood flow/pressure, and digestion. It is essential when exercising since it controls your heart to pump blood and deliver oxygen throughout your body; respiration provides the energy you need when playing sports and oxygen to your heart.
Neurons
However, we can go into further analysis, as three types of neurons transmit information throughout your body: sensory neurons, interneurons, and motor neurons. Sensory and motor neurons are located in the PNS (Peripheral Nervous System), while the CNS (Central Nervous System) holds the interneurons.
When you react to something, your body decides what it should do by sending impulses throughout the body.
Sensory Neurons
First, sensory neurons convey the information from the sensory organs (PNS) into the CNS.
Interneurons
The interneurons receive the impulses from sensory neurons in the CNS then relay the brain's response to motor neurons.
Motor Neurons
Finally, motor neurons transport impulses from the spinal cord (CNS) to the muscles or glands in your body.
Why don’t mosses grow very tall?
They need energy to make food, which they get by being close to the ground.
They don’t have roots, so they must be near water.
They need to send out spores via water.
They have seeds that need to roll away.
Answer:
Hello~
Llamalover here!
Mosses have some water-conducting cells, but they do not have the empty, lignin-reinforced cells that allow vascular plants to transport water with strong pressure gradients. Thus, mosses have very limited water transport ability and can't grow very tall.
So, your answer is They need to send out spores via water. I believe
