Answer: I predict that human use of fossil fuels will affect their distribution over time because.

Explanation: Because if we keep on using fossil fuels over and over we eventually loose all of it because nearly 67% of the worlds reserves of crude oil are currently in the Middle East. So if we keep on using it well then there won't be anymore fossil fuels left for us, And if we keep using it, it will also slowly kill us off and also kill everything else around us.

Answer:

a population in Florida.

Explanation:

In the report, the biologist is describing a population in Florida. A population is a group of organisms of the same species that live in a particular area and can interbreed with one another. In this case, the rattlesnakes are a population of the same species that live in Florida and can reproduce together. The report includes statistics about the population's size, breeding rate, and characteristics, which are all typical of a population analysis. A community refers to all the different populations of species that coexist in a particular area, while a biome refers to a large geographic area with similar climate and vegetation. An organism refers to an individual living thing.

The lymph flows back to the circulatory system through the lymphatic vessels and subclavian vein.

This system helps to keep the body cells moist by collecting excess fluid from tissues and depositing them in the bloodstream.

The lymphatic vessels empty the lymph into the right and left lymphatic duct which are connected to the subclavian vein thereby aiding their deposition into the bloodstream and reaching the upper trunk and lower extremities .

A cycle component known as an exchange pool temporarily stores an element or water. The ecosystem, for instance, serves as a water exchange pool. It typically only retains water  for a short period of time.

We attempt to quantify the amount of energy and matter that is stored. For many types of energy and matter, pools are typically prevalent. Oceans, for instance, contain both water and carbon pools.

Because of the hydrologic cycle, water may reach us, plants, and animals. The movement of nutrients, pathogens, and sediment into and out of aquatic environments occurs in addition to the provision of water for people, animals, and plants.

The ratio between 92 mL and 3.0 fl oz is 46 : 44, or it can be further simplified to 23 : 22.

To find the ratio between 92 mL and 3.0 fl oz, we need to convert the units to a common measurement. Let's convert 3.0 fl oz to milliliters (mL).

1 fluid ounce (fl oz) is equal to approximately 29.5735 milliliters (mL).

Therefore, 3.0 fl oz is equal to 3.0 * 29.5735 = 88.72 mL (rounded to two decimal places).

Now we can express the ratio between 92 mL and 88.72 mL:

92 mL : 88.72 mL

Simplifying the ratio by dividing both sides by the greatest common divisor, we get:

46 : 44

So, the ratio between 92 mL and 3.0 fl oz is 46 : 44, or it can be further simplified to 23 : 22.

Answer:

Answer:

Peripheral vascular resistance (systemic vascular resistance, SVR) is the resistance in the circulatory system that is used to create blood pressure, the flow of blood and is also a component of cardiac function. When blood vessels constrict (vasoconstriction) this leads to an increase in SVR.

The relationship between BP and viscosity is such that, given a constant systolic BP, if blood viscosity increases, then the total peripheral resistance (TPR) will necessarily increase, thereby reducing blood flow. Conversely, when viscosity decreases, blood flow and perfusion will increase.

The respiratory system and lungs work very closely with the cardiovascular system for the uptake and elimination of gases and the distribution of energy in the body.

Oxygen from the air is absorbed into the bloodstream through the lungs. When it reaches the lungs, the function of the cardiovascular system begins, since that is where the non-oxygenated blood is oxygenated and returns to the heart.

When in the cardiovascular system, the blood reaches the capillaries in the tissues, oxygen is released, which the cells use to produce energy. These cells release waste products, such as carbon dioxide and water, which are absorbed and transported by the blood.

O2 and CO2 are constantly circulating and passing from one medium to another, so much so that O2 passes, along with other gases, from the atmosphere to the airways, entering through the nostrils and driving through the larynx, trachea, source bronchi, terminal bronchioles, respiratory bronchioles, alveolar sacs and alveoli.

Therefore, The respiratory system and lungs work very closely with the cardiovascular system for the uptake and elimination of gases and the distribution of energy in the body.

Answer:

LIGHT ENERGY is converted to CHEMICAL ENERGY in the process of PHOTOSYNTHESIS

Explanation:

According to the law of conservation of energy, energy cannot be created nor destroyed but can only be changed from one form to another. This means that no form of energy gets destroyed but only transformed. This is evidently so in so many natural processes including the process of PHOTOSYNTHESIS undergone by plants.

Photosynthesis, which is the way plants obtain their food via sunlight, converts the LIGHT ENERGY of the sun to CHEMICAL ENERGY in glucose produced. Hence, photosynthesis obeys the law of conservation of energy.

Answer:

Explanation:

An information system can be defined as a set of components or computer systems, which is used to collect, store, and process data, as well as dissemination of information, knowledge, and distribution of digital products.

Generally, it is an integral part of human life because individuals, organizations, and institutions rely on information systems in order to perform their duties, functions or tasks and to manage their operations effectively. For example, all organizations make use of information systems for supply chain management, process financial accounts, manage their workforce, and as a marketing channels to reach their customers or potential customers.

Additionally, an information system comprises of five (5) main components;

1. Hardware.

2. Software.

3. Database.

4. Human resources.

5. Telecommunications.

Hence, an information system interacts with the overall system by receiving data in its raw forms and information in a usable format.

In this scenario, Mother Goose Computing, Inc. are currently updating several of their systems. For the genomics division, it's planning to replace the old system by the new one all at once. Thus, this is called a direct conversion.

Direct conversion can be defined as a process which typically involves the establishment and implementation of a new system followed by an immediate discontinuation of the old system all at once. Thus, on a particular date and time, the old system would be discontinued while the new system is immediately adopted for use in the particular organization.

Answer:

1. Muscle tissue.

2. Epithelial tissue.

3. Nervous tissue.

4. Connective tissue.

5. Epithelial tissue.

6. Muscle tissue.

7. Connective tissue.

Explanation:

A tissue can be defined as a group of cells that are structurally similar and in close proximity. Tissues are generally responsible for performing specific functions in living organisms such as humans, animals and plants. Therefore, tissues in living organisms function together as a unit.

There are four main types of tissues and these includes;

I. Connective tissue.

II. Epithelial tissue.

III. Muscle tissue.

IV. Nervous tissue.

In this scenario, the various types of tissues are matched with their functions as follows;

1. Muscle tissue: propels food through the digestive tract. It is mainly performed by peristalsis.

2. Epithelial tissue: lines internal and external body surfaces. It also referred to as epithelium and it comprises of sheets of cells.

3. Nervous tissue: conducts electrical impulses. A neural circuit can be defined as a group of neurons in the body of a living organism which are interconnected by synapses to perform specific functions when they're activated.

4. Connective tissue: transports oxygen to the body tissues predominantly through the Erythrocytes (red blood cells).

5. Epithelial tissue: functions in secretion and absorption.

6. Muscle tissue: pumps blood.

7. Connective tissue: stores fats and minerals.

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.
