the number of fruit per plant
the amount of light each plant receives
the height of each plant
the average circumference of each plant’s fruit

Answers

Answer 1

Answer:

The answer is "the amount of light each plant receives

Answer 2

At the time of graphing the data, the factor that should be considered as the independent variable should be the light amount that each plant received.

What is the plant?

The plant should be treated as a living thing that should be grown in the earth and contains the stem, leaves, and roots.

At the time when the gardener performed the experiments on the tomato plants so here, the factor should be the light amount that each plant received.

Answers

It’s hard brother! Pool

Huntington’s disease (HD) is prevalent South Africa. Most of the families with HD have Dutch or British ancestry, which suggests they inherited the European HD allele. HD is believed to have first arrived in South Africa more than 300 years ago when Dutch colonists settled into the Western Cape in the 1600s. Thus, the prevalence of HD in South Africa is the result of the founder effect.

Mutations in the HTT gene cause Huntington’s disease. The HTT gene provides instructions for making a protein called huntintin. This protein plays a role in nerve cells in the brain. The HTT mutation that causes HD involves a DNA segment known as a CAG trinucleotide repeat. This segment is made up of a series of three DNA building blocks that appear multiple times in a row. Normally, the CAG segment is repeated 10 to 35 times within the gene. In people with HD, the CAG segment is repeated 36 to more than 120 times. An increase in the size of the CAG segment leads to the production of an abnormally long version of the huntintin protein. This causes the dysfunction and eventual death of neurons in certain areas of the brain. The more repeats, the more serious the disease is.

HD is inherited in an autosomal dominant pattern. There is both an adult onset (after reproductive age) and a juvenile onset pattern. People with adult onset typically have 40 to 50 repeats, while people with the juvenile form tend to have more than 60 repeats. Individuals who have 27 to 35 repeats do not develop HD, but they are at risk of having children who will develop the disorder. As the gene is passed on to offspring, the size of the repeat may lengthen into the range associated with HD.

Predict what will happen to the allele frequencies for Huntington’s disease in South Africa if there were a new mutation to the HTT gene that causes a reduction to the CAG trinucleotide repeat. Justify your prediction with evidence. Your response should include links to the sources of information gathered.

The process in which insulin is released, wrapped in a sac and moved across a cell membrane to enter the bloodstream and circulate until it finds its target cell is called exocytosis.

Exocytosis is the process by which a cell releases materials to the exterior by fusing a vesicle containing the materials with the cell membrane and forcing its contents out of the cell. It is an active transport process in which the materials to be transported are packaged in vesicles and secreted out of the cell by fusion with the plasma membrane. In this case, insulin is secreted from the pancreatic beta cells into the bloodstream by exocytosis.

a candy factory in las vegas recycles its wastewater from the factory and local area to fertilize a community garden. which process affecting the nitrogen cycle is reduced due to these conservation efforts? responses nitrogen fixation nitrogen fixation eutrophication eutrophication acid rain acid rain photosynthesis

Answers

Answer:

Eutrophication

Explanation:

See the image attached! Please like and give your rating, this will help me a lot! :)

The process affecting the nitrogen cycle that is reduced due to the conservation efforts of a candy factory in Las Vegas is eutrophication. Let's learn more about eutrophication and the nitrogen cycle.

Eutrophication: It is a process that happens when excessive nutrients such as nitrogen and phosphorus are introduced into a water body, leading to an overgrowth of algae and other plants. The overgrowth of these plants can cause a decrease in dissolved oxygen levels in the water, leading to the death of fish and other aquatic life forms. The reduction of eutrophication can be done by reducing the number of nutrients present in the water or by preventing their introduction into the water body. Thus, the reduction of eutrophication can help in the conservation of aquatic life and promote a healthy environment.

Nitrogen Cycle:The nitrogen cycle is the process by which nitrogen is converted from its gaseous form in the atmosphere into a form that can be used by living organisms. This process involves several steps, including nitrogen fixation, nitrification, assimilation, and denitrification. Nitrogen fixation is the process by which atmospheric nitrogen is converted into a usable form by bacteria. The bacteria then release the nitrogen into the soil, where plants can absorb it. Thus, nitrogen is an essential nutrient required for plant growth. Fertilizers containing nitrogen are added to soil to improve the soil's fertility and promote plant growth. However, excessive use of fertilizers can lead to the release of nitrogen into water bodies, resulting in eutrophication.

In conclusion, the conservation efforts of a candy factory in Las Vegas that recycles its wastewater to fertilize a community garden will help reduce the process affecting the nitrogen cycle that is eutrophication. This is because the recycling of wastewater will prevent the release of excessive nutrients such as nitrogen into water bodies, which would otherwise lead to the overgrowth of algae and other plants and negatively impact aquatic life.

When the bond is broken, high energy electrons are released and carried by NADH to go to the Electron Transport Chain.

What initiates an action potential on a muscle cell?

a. Acetylcholine binding to receptors on the sarcolemma within the neuromuscular junction

b. Acetylcholinesterase

c. Myosin cross bridges binding to actin

d. Atp?

Answers

The correct option that initiates an action potential on a muscle cell is a. Acetylcholine binding to receptors on the sarcolemma within the neuromuscular junction. (optoin a)

An action potential is an electrical signal that triggers the contraction of muscle cells. In order for an action potential to occur in a muscle cell, several steps are involved:

Nerve Impulse: A nerve impulse, or action potential, is generated in a motor neuron, which carries the signal from the central nervous system to the muscle.

Neuromuscular Junction: The nerve impulse reaches the neuromuscular junction, which is the point of connection between the motor neuron and the muscle cell.

Acetylcholine Release: The nerve impulse stimulates the release of acetylcholine, a neurotransmitter, from the motor neuron into the synaptic cleft of the neuromuscular junction.

Acetylcholine Binding: Acetylcholine diffuses across the synaptic cleft and binds to receptors on the sarcolemma, which is the cell membrane of the muscle cell.

Sodium Influx: The binding of acetylcholine to the receptors triggers the opening of ion channels, allowing sodium ions to flow into the muscle cell.

Depolarization: The influx of sodium ions causes a change in the electrical potential of the muscle cell, leading to depolarization.

Action Potential: If the depolarization reaches the threshold level, it triggers the generation of an action potential along the sarcolemma and into the muscle cell.  (optoin a)

The tractor originally cost $134,000 with accumulated depreciation of $68,100. The proceeds from the insurance company were $94,500.The company should recognize:a. A gain of $28,600.b. A gain of $65,900.c. A gain of $94,500.d. A loss of $65,900.e. A loss of $28,600. What should be the role(s) of the media in our society (a watch dog, provide political analysis, entertainment, sports, all of these, none of these, other roles, etc.)? 2. Are there particular media outlets (networks, cable channels, magazines, newspapers, websites, etc.) that do a "good job" of fulfilling the role(s) you stated in Question 1? Any that don't live up to your expectations? An engineer working for a large agribusiness has developed two types of soil additives he calls Add1 and Add2. The engineer wants to estimate the difference between the mean yield of tomato plants grown with Add1 and the mean yield of tomato plants grown with Add2. The engineer studies a random sample of 12 tomato plants grown using Add1 and a random sample of 13 tomato plants grown using Add2. (These samples are chosen independently.) When he harvests the plants he counts their yields. These data are shown in the table. Yields (in number of tomatoes) Add1 162, 168, 175, 167, 181, 180, 187, 171, 167, 191, 166, 172 Add2 178, 185, 185, 227, 145, 202, 218, 211, 156, 164, 173, 194, 166 Send data to calculator V Assume that the two populations of yields are approximately normally distributed. Let be the population mean yield of tomato plants grown with Add1. Let be the population mean yield of tomato plants grown with Add2. Construct a 90% confidence interval for the difference . Then find the lower and upper limit of the 90% confidence interval. Carry your intermediate computations to three or more decimal places. Round your answers to two or more decimal places. (If necessary, consult a list of formulas.) ? Suppose the average income for consumers of a product increased from $80,000 per year to $84,000 per year. And suppose this causes the number of units sold of this product to increase from 32,000 to 33,000. (a) Calculate the income elasticity of demand for this product. (b) Is this product a normal good or an inferior good? a 15.50 gram ice cube at 0.00c is left out on the counter. after a couple of hours, it absorbs 6,667 joules of heat. what is the final temperature of the water remaining? Use the following information to answer the next two questions. Consider the Phillips curve t=-(Ut-U*) with =1.5, u*=0.06, and n=0.05. Suppose that uo-u*. Suppose the current government pressures the RBA to bring the economy to an unemployment rate of 0.04 for the next period. With adaptive expectations, what inflation rate should the RBA target? A 0.100 M oxalic acid, HO2CCO2H, solution is titrated with 0.100 M KOH. Calculate the pH when 25.00 mL of oxalic acid solution is titrated with 35.00 mL of NaOH. Ka1 = 5.4 102 and Ka2 = 5.42 105 for oxalic acid. Write a function that receives a StaticArray that is sorted in order, either non-descending or non-ascending. The function will return (in this order) the mode (most-occurring value) of the array, and its frequency (how many times it appears). If there is more than one value that has the highest frequency, select the one that occurs first in the array. You may assume that the input array will contain at least one element and that values stored in the array are all of the same type (either all numbers, or strings, or custom objects, but never a mix of these). You do not need to write checks for these conditions. For full credit, the function must be implemented with O(N) complexity with no additional data structures being created. A thin, rectangular sheet of metal has mass M and sides of length a and b. Use the parallel-axis theorem to calculate the moment of inertia of the sheet for an axis that is perpendicular to the plane of the sheet and that passes through one corner of the sheet.
