Answers
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.

Abe knew from his anatomy class that there are three different kinds of muscle tissue in the body. He knew lifting weights would help build the skeletal muscle and that running was good for cardiac muscle health. He was surprised to find out that his blood vessels had smooth muscle, so his exercise regimen was actually benefitting all the muscle types of his body.

Answers
Answer:
SKELETAL MUSCELES CARDIAC MUSCLES SMOOTH MUSCLES
Explanation:
SKELETAL MUSCLES -: There are long, cylindrical, and striated skeletal muscle cells. They are multi-nucleated, which means they have more than one nucleus. This is because from the fusion of embryonic myoblasts, they are created. Each nucleus controls the sarcoplasm's metabolic demands around it. There are high energy requirements for skeletal muscle cells, because they contain several mitochondria in order to generate adequate ATP. Examples of skeletal muscles: arms and legs- The muscles that belong to the arms and legs feature in pairs. Abdomen and Back- These muscles are connected to the various sets of skeletal muscles that run across the torso.CARDIAC MUSCLES -: Cardiomyocytes have a short and narrow outline and are fairly rectangular. They are about 0.02 mm wide and 0.1 mm (millimetres) long, respectively. There are many sarcosomes in cardiomyocytes, which provide the required energy for contraction. Cardiomyocytes usually contain a single nucleus, unlike skeletal muscle cells. Cardiomyocytes, although they contain more sarcosomes, normally contain the same cell organelles as skeletal muscle cells. example - cardiac muscle is present in heart. SMOOTH MUSCLES -: Smooth muscle cells have a single central nucleus and are spindle-shaped. They range in length from 10 to 600 μm (micrometers), and are the tiniest type of muscle cell. In the expansion of organs like the kidneys , lungs, and vagina, they are elastic and therefore essential. As in cardiac and skeletal muscle, the myofibrils of smooth muscle cells are not aligned, meaning they are not striated, hence the term smooth. example of smooth muscles -: Walls of blood vessels , Walls of stomach , Ureters , Intestines , In the aorta (tunica media layer), Iris of the eye. ,Prostate and Gastrointestinal Tract.
EVOLUTION CONNECTION The result of mitosis is that the daughter cells end up with the same number of chromosomes that the parent cell had. Another potential way to maintain the number of chromosomes would be to carry out cell division first and then duplicate the chromosomes in each daughter cell. Do you think this would be an equally good way of organizing the cell cycle
Answers
Answer:
No, because it would lead to chromosome mosaicism
Explanation:
Chromosomal mosaicism can be defined as the presence of two or more cell populations with a distinct number and/or type of chromosomes in the cells of an organism. If the cell would split before chromosome duplication, it would lead to the fact that some cells would have one chromosome of the homologous pair being duplicated, while other cells would have duplicated the other one. In consequence, this process would produce a genomic imbalance between different cell populations that would be expected to be lethal for the organism.

Ocean Salinity Increases
Ocean Salinity Decreases
Answers
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.

Why might it be an issue to cut the trees down to build a home/shelter? How would that impact the respiration/photosynthesis cycle?
Answers
Answer:
Trees are one of the most important things lives
Because the trees take our carbon dioxide and gives us oxygen in return. It will also low the rate of oxygen provided by trees leading to may be increase in the global warming rate, and also production of heat and suffocation in crowded rooms
Oxygen comprises only about 21 percent of air's chemical component. Yet, it is extremely important to life on earth. Living organisms, from single-celled animals to humans, use oxygen to produce the energy required to sustain them. Since trees are larger plants, their production of oxygen is significant. It is estimated that tropical rainforests, produce 40 percent of the earth's oxygen even though they cover only about 6 percent of the land. Rainforests in the Amazon have declined by 17 percent in the last 50 years as a result of deforestation.

Oxygen-rich blood is carried through pulmonary arteries from the lungs to the heart?
Answers
It is false that oxygen-rich blood is carried through pulmonary arteries from the lungs to the heart.
What is pulmonary artery?The two principal arteries leaving the right ventricle of the heart are known as the pulmonary arteries. Low-oxygen blood is seen in this lower chamber of the heart. This blood travels to the lungs through the pulmonary arteries.
The middle mediastinum contains the main pulmonary artery, as well as the pulmonary arteries that follow on the right and left. They emerge from the four chambered heart's right ventricle and carry blood to the lungs.
Right side of heart sends deoxygenated blood to pulmonary artery. Nature has made it such that this blood reaches the lungs where carbon dioxide can be released and then oxygen can be loaded.
It is true that all arteries convey oxygenated blood, with the exception of the pulmonary artery.
Thus, the given statement is false.

When the body is attacked by a foreign substance, the _____ defenses are the first to react.
Answers
Answer:
Correct answer is "non specific defenses"
Answer:
non specific
Explanation:
When the body is attacked by a foreign substance, the non specific defenses are the first to react.
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.
Answers
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 effect if any of this mutation on the amino acid chain produced
Answers
Answer:
A missense mutation is a mistake in the DNA which results in the wrong amino acid being incorporated into a protein because of change, that single DNA sequence change, results in a different amino acid codon which the ribosome recognizes. Changes in amino acid can be very important in the function of a protein.
Explanation:
Hope this helps
The effect if any of the mutations on the amino acid chain produces that change is called a "missense mutation," because in this type of mutation, the amino acid gets changed.
What is the significance of the types of mutations?There are many different types of mutations that occur during polypeptide formation, such as those that occur but have no effect on the overall structure and function of the enzyme, proteins, etc.; these are known as "silent mutations," while others result in single amino acid changes and are known as "missense mutations." It has many implications, such as in sickle cell anemia, where a single amino acid change causes a change in the hemoglobin structure.
Hence, the effect if any of the mutations on the amino acid chain produces that change is called a "missense mutation," because in this type of mutation, the amino acid gets changed.
