Determine the stimulus, receptor, control center response, and effector for gas exchange in plants
PLEASE HELP ME ITS URGENTTTTTTTT

Answers

Answer 1

Answer:

The exchange of oxygen and carbon dioxide in the leaf (as well as the loss of water vapor in transpiration) occurs through pores called stomata (singular = stoma). Normally stomata open when the light strikes the leaf in the morning and close during the night.

Stomata (the receptors of gas exchange process) are tiny holes found in the underside of leaves. They control water loss and gas exchange by opening and closing. They allow water vapour and oxygen out of the leaf and carbon dioxide into the leaf. In low light the guard cells lose water and become flaccid, causing the stomata to close.

Answer 2

Stomata, which are microscopic pores on leaves and stems that act as receptors in gas exchange, are common in plants.

Stimulation, which is caused by things like light and the environment, demands gas exchange. The plant's internal regulatory system, the control center, initiates the opening or closing of the stomata. The effectors, the guard cells, regulate the size of stomatal pores to facilitate this response. When under stress, the stomata close to prevent water loss and open to allow the entry of carbon dioxide for photosynthesis. By absorbing carbon dioxide and releasing oxygen during photosynthesis, this exchange enables plants to maintain a stable water balance by controlling transpiration.

A student astronomer went outside and made two observations of the Moon that were several days apart. Her observations are shown in the diagram above. The light part of the Moon appeared to get smaller over time. Why did this happen?

Answers

Answer:

The light part of the Moon appeared to get smaller over time because of the change in the relative position of the Moon, the Sun, and the Earth. This is known as the lunar phase. The changing appearance of the Moon from the Earth's perspective is caused by the Moon's orbit around the Earth and the position of the Moon and Sun relative to the Earth. The Moon's phases are caused by the angle between the Moon, Earth, and Sun changing, as the Moon orbits the Earth. When the Moon is between the Earth and the Sun, the side facing the Earth is not illuminated by sunlight, so it appears dark, and this is called a new moon. When the Moon is on the opposite side of the Earth from the Sun, the entire side of the Moon facing the Earth is illuminated by sunlight, so it appears full, and this is called a full moon. As the Moon moves in its orbit, the angle between the Sun, Earth, and Moon changes, causing the illuminated portion of the Moon visible from the Earth to change, leading to different lunar phases.

1. Differentiate foreign investment from the types of aid provided by the UNDP and World Bank, citing specific examples of aid from both.

SOMEONE PLEASE HELP!

Answers

Foreign investment and the types of aid provided by the United Nations Development Programme (UNDP) and the World Bank are distinct in their nature, purpose, and mechanisms.

Foreign investment refers to the investment made by individuals, companies, or governments of one country into another country's economy with the expectation of generating a return. It involves the allocation of financial resources to productive sectors, such as industries, infrastructure, or services. Foreign direct investment (FDI) is a common form of foreign investment, where a company establishes operations or acquires assets in another country.

On the other hand, the UNDP and the World Bank primarily focus on providing different types of aid to countries, particularly those facing socio-economic challenges. Aid from these organizations is aimed at promoting development, reducing poverty, and addressing various global issues. The UNDP focuses on human development, providing assistance in areas such as education, healthcare, gender equality, environmental sustainability, and governance.

The World Bank provides financial and technical assistance to developing countries through loans, grants, and policy advice. It aims to support economic development, infrastructure projects, poverty reduction, and social welfare programs. Examples of World Bank aid include funding for building schools, hospitals, roads, or water supply systems in developing nations.

In summary, foreign investment involves the allocation of financial resources by individuals or entities for profit-making purposes in another country's economy. On the other hand, the UNDP and the World Bank provide various forms of aid to support development, address global challenges, and improve socio-economic conditions in developing countries.

Describe how the components of a meal containing fried fish and toast bread will be processed as they move through the digestive system of man​

Answers

Answer:

Explanation:

When a meal containing fried fish and toast bread is consumed, it goes through a series of processes in the digestive system of a human. Here's a general description of how the components are processed:

1. Mouth: The process of digestion begins in the mouth. Chewing breaks down the toast bread and fish into smaller pieces, while saliva mixes with the food to start the breakdown of carbohydrates.

2. Esophagus: The chewed food, now called a bolus, is swallowed and travels down the esophagus through peristaltic contractions. The esophagus carries the food to the stomach.

3. Stomach: The stomach is responsible for further mechanical and chemical digestion. It mixes the food with stomach acid and digestive enzymes to break down proteins. The fried fish is broken down into smaller pieces through mechanical churning.

4. Small Intestine: The partially digested food leaves the stomach and enters the small intestine. Here, bile from the liver and enzymes from the pancreas break down fats, while other enzymes continue the breakdown of proteins and carbohydrates. Nutrient absorption occurs through the walls of the small intestine and is facilitated by small finger-like projections called villi.

5. Large Intestine: Any remaining undigested food, as well as water and electrolytes, pass into the large intestine. The large intestine absorbs water and electrolytes while forming waste material known as feces.

6. Rectum and Anus: The feces are stored in the rectum until elimination through the anus occurs during a bowel movement.

Throughout this process, various digestive enzymes and gastric juices are secreted at different stages to facilitate the breakdown and absorption of nutrients. The fried fish and toast bread are broken down into smaller molecules, such as proteins, carbohydrates, and fats, which are then absorbed into the bloodstream to provide energy and nourishment for the body.

ASAP!!!A scientist designed an experiment to test where a plant's matter came from. She
measured the starting mass of a willow tree, the soil, and the container. After five
years, she repeated the measurements and observed that the tree gained 74 kg (164
lbs) but the soil had not changed much at all (only lost 57 g, approximately 0.12 lbs).
1. Use evidence, from the results, to explain that the idea that the mass of a tree
comes from the soil, is incorrect. 2 points
2. Why is it incorrect to say that the tree's mass comes from sunlight? 1 point
3. If the mass of the tree does not come from the soil or sunlight, explain the trees
increase in mass. 2 points

Answers

Explanation:

The fact that the soil did not change significantly after five years, while the tree gained 74 kg, suggests that the tree's mass did not come from the soil alone. If the tree had gained all its mass from the soil, the soil would have lost an equivalent amount of mass, which did not occur. Therefore, this evidence suggests that the mass of a tree does not come solely from the soil.

While sunlight is necessary for photosynthesis, which allows the tree to produce glucose, the mass of a tree does not come directly from sunlight. Rather, the tree uses the glucose produced during photosynthesis to build its own tissues, such as leaves, branches, and roots. Therefore, while sunlight is necessary for the tree to grow, it is not the source of the tree's mass.

The tree's increase in mass is primarily due to the process of photosynthesis. During photosynthesis, the tree uses energy from sunlight to convert carbon dioxide and water into glucose, which it then uses to build new tissues. Additionally, the tree may have also taken up nutrients, such as nitrogen and phosphorus, from the soil, which it incorporated into its tissues. However, it's important to note that the majority of the tree's mass comes from the carbon that it takes up during photosynthesis, rather than the nutrients in the soil.

Explain how diffusion restored homeostasis during the dialysis treatment.

Answers

During dialysis, diffusion facilitates the movement of waste products and excess fluids out of the blood, restoring homeostasis.

During dialysis treatment, diffusion plays a crucial role in restoring homeostasis. Homeostasis refers to the body's balanced state, where the levels of various substances are maintained within a narrow range. In the context of dialysis, diffusion refers to the movement of solutes across a semipermeable membrane.In hemodialysis, the patient's blood is circulated through a dialyzer, which contains a semipermeable membrane. On one side of the membrane, the patient's blood flows, while on the other side, a dialysate fluid flows. Due to a concentration gradient, solutes like urea, creatinine, and excess electrolytes in the blood diffuse across the membrane into the dialysate fluid.This diffusion process helps remove waste products and excess fluids from the blood, bringing it closer to the normal physiological range. By restoring the balance of solutes and maintaining proper fluid levels, diffusion in dialysis aids in restoring homeostasis and promoting the overall well-being of the patient.

D. The mRNA will be changed from U-A-C to T-A-C during translation.​

Answers

Answer:

C. The mRNA will be changed from U-A-C to U-A-G during transcription.

Explanation:

Transcription is the process where the mRNA strand is formed, using a DNA strand as a template strand.

The bases on an mRNA are adenine [A], uracil [U], guanine [G] and cytosine [C], where adenine is complementary to uracil and guanine is complementary to cytosine.

[Translation is the process where a polypeptide chain- a sequence of amino acids, is formed. tRNA molecules carry specific amino acids and bind to the codon on the mRNA which is complementary to the anticodon on the tRNA. Thus option A and D is wrong.]

[Option B is wrong because the bases are not complementary.]

Why there were no clear zones for using LB media with 1% olive oil for screening lipilytic bacteria

Answers

The reason for the clear zone may be that there is Insufficient lipolytic activity.

Why the clear zone?

The absence of clear zones when using LB media with 1% olive oil for screening lipolytic bacteria could be due to Insufficient lipolytic activity.

Enzymes called lipases, which are produced by lipolytic bacteria, break down fats and oils. It's possible that the bacteria utilized in the experiment won't create lipases or have poor lipolytic activity, which would prevent them from efficiently hydrolyzing the olive oil in the media. There wouldn't be any observable clearing or lipid hydrolysis zones as a result.

Sinai('Sinai') hospitals are planning to merge. Together, they must design a new employee benefits plan that will cover all employees in the merged hospital. To save on administration costs, they have decided to adopt for the entire merged hospital either Mary's plan or Sinai's current plan. The table below shows that Sinai's average benefits are more generous than Mary's. For example, and employee with a family received, on average, $550 in annual benefits under Mary's plan and $830 in benefits under Sinai's plan. In total, the employee with a family would receive an average of $550+$90+$40+$15=$695 under Mary's plan and significantly more under Sinai's. overall, 65% of all employees at both hospitals enroll under a family plan and the remainder enrolls under the individual plan. The table displays average benefits, but either decision will significantly reduce benefits for some employee. Mary has 1200 employees, and if Sinai's plan is adopted then 12% of Mary's employees are expected to leave because of the reduction in benefits. Sinai has 750 employees, and if Mary's benefits are adopted then 30% are expected to leave Sinai. On average, it will cost $45,000 to replace an employee who leaves either hospital.
