In a parallel circuit, there is only one path for current to take. Please select the best answer from the choices provided T F
Answer:
False.
Explanation:
A parallel circuit has more than one path for current flow. The number of current paths is determined by the number of load resistors connected in parallel. Total current in a parallel circuit is the sum of the individual branch currents.
What contribution to energy do carbohydrates make?
Answer:
Carbohydrates are the nutrients most frequently used as an energy source (containing 4kcal per gram), as they are fast-acting and turn into energy as soon as they are ingested. This energy powers the brain and body. The energy that powers the brain and body is generated when carbohydrates are broken down.

A parent with the blood type A (genotype AO) and a parent with blood type B (genotype BO) have children with blood types A, B, and AB. What type of inheritance pattern is shown by the child with type AB blood and why?
Answer:
Co-dominance because he expresses both of the alleles simultaneously
Explanation:
The ABO blood group system is used by humans. This blood group type is controlled by multiple alleles. Alleles A and B are both dominant over allele O but are co-dominant. Co-dominance is a type of inheritance pattern in which two alleles of a gene both express themselves i.e. neither is recessive.
This is the case of this family whose parents have a genotype of AO (blood type A) and BO (blood type B) respectively. The children have blood types A, B, and AB. However, the child with genotype AB possesses both the A and B allele, which are both expressed in his blood group (phenotype), hence, it can be said that the child is exhibiting CO-DOMINANCE for the blood group trait.
The inheritance pattern is co-dominance.
The genotype of an individual is the sum total of the genes that the individual has received from parents. When two genes are expressed at the same time, the inheritance pattern is called co-dominance.
Hence, the child that has a blood type AB has both A and B expressed and this is co-dominance.

Because cilia cannot function properly, smokers have a frequent headache.
True
Answer:
Explanation:
The cilia sweep out mucus and dirt so your lungs stay clear. Smoking temporarily paralyzes and even kills cilia. This makes you more at risk for infection. Smokers get more colds and respiratory infections than non-smokers.
Because cilia cannot function properly, smokers having a frequent headache is a true statement.
What is Cilia?These are tiny hair projections which are found in the airway of the body and helps to prevent dust or foreign matter from getting to the lungs.
Smoking destroys it and leads to insufficient oxygen inhaled by the body as a result of presence of contaminants which may therefore lead to headache.

what is theory of to observe the neucles in cheek cells
Answer: The theory of cheek cells is used for the identification of cheek cells.
Explanation:
The cells of cheek do not have cell wall. They have a cell membrane which allows on certain molecules to pass through it. The nucleus is located centrally in the cheek cells and it stores the DNA. It can be stained with the help of the methylene blue reagent. It appears blue in color which can be observed under the microscope. The cheek cells can be isolated from the buccal cavity by using cotton buds and cotton swabs can help in isolating the cells.

Cytosine-
Adenine-
Thymine-
Answer:
Cytosine: 10%
Adenine: 40%
Thymine: 40%
Explanation:
So we know that Cytosine and Guanine are complementary and Adenine and Thymine are complementary.
Cytosine would be 10%
What's left is 80%, which would be divided by two because adenine and thymine have the same percents.
Adenine: 40%
Thymine: 40%

3. Design and describe an experiment using celery stalks to demonstrate how certain conditions will cause a loss or gain of turgor pressure. In order to follow the scientific method, your description should start with an observation and be followed by (i) a testable hypothesis, (ii) an outline of the experiment that will test the hypothesis, (iii) a description of the type of data that will be collected, and (iv) a possible conclusion that could likely be made after completing the experiment
Answer:
Explanation:
A way you can use celery stalks to demonstrate the conditions with loss or gain of turgor pressure, is by setting us the same situation with water. I. You could possibly make a chart with how the celery could change. II. Testing the different out comes of the celery changing and what it has done and if it matches the hypothesis. III. The type of data you could conduct would be is seeing the height, length, and width. As wellas trying to see how much celery would soak up. IV. A possible conclusion of that experiment would be that the celery stalks would all expand expect for the one not in any water and it all would possibly start to grow into more than one celery and sprout. H2OH2O
Turgor pressure is the pressure due to fluid in a cell, that provides a force making the plasma membrane to push upon the cell wall
The responses and reasons for the experiment demonstrating the conditions by which turgor pressure is lost or gained are as follows:
Observation: Cut celery placed in water are fresher and are not as wilted than cut celery placed on a table without water, or placed in a salt solution
(i) A testable hypothesis is given as follows;
Hypothesis: The turgor pressure is gained by increasing the hypotonicity of the water that the celery stalks is placed into
(ii) An outline of an experiment to test the hypothesis is presented as follows;
Procure three celery ticks and three beakers that can contain a stick eachPlace 100 mL fresh water from the tap into one of the beaker, 100 mL of 5% salt solution into the second and 100 mL 10% salt solution into the third beaker, and label the beakersMeasure and record the mass and sizes of celery stalk lengths cut to 5 cm length and identically sized, after which they are placed one each into each beaker Take a picture of the sticks in the containers that shows the sizes of the sticks, and also write a note describing each stick in the lab notebookPlace the containers into the fridge overnightMeasure and record the parameters of the sticks removed from the fridge and take a picture of the sticks with a ruler by the side of the container to show the size of the sticksRecord the observation(iii) A description of the type of data that will be collected include, the width, mass and length of each celery
(iv) A possible conclusion that could likely be made after completing the experiment is that the gain in turgor pressure is directly related to the hypotonicity of the solution the stick of celery stalk is placed

What is the gradient (change in elevation/length of river) of the Naugatuck River?
Answer:
As the river flows south from Torrington to Derby it drops approximately 540 feet in elevation, resulting in a relatively steep gradient of approximately 13 feet per mile. Consequently, the river is a predominantly rapidly flowing river for most of its length, characterized occasionally by rapids.

What materials do motor neurons need to survive and how do they get those materials?
Answer:
Neurons are made up of three major parts: a cell body, or soma, which contains the nucleus of the cell and keeps the cell alive; a branching tree like fiber known as the dendrite, which collects information from other cells and sends the information to the soma; and a long, segmented fiber known as the axon, which transmits information away from the cell body toward other neurons or to the muscles and glands.
