In assessing a stroke patient, you ask her to stick out (protract) her tongue. you note that it deviates to one side. you suspect that damage to the neural control of the ________ muscle has occurred.

The type of cell that does not contain a genetic material but has a presence of nucleus is a prokaryotic cell.  The prokaryotic cell are considered to be an organism that is unicellular because of the reason that the organelle that it has are lacking. 

Cells without a nucleus are prokaryotic cells, such as bacteria and blue-green algae. They have free-floating DNA as they lack a nuclear membrane. Some eukaryotic cells, like mature human red blood cells, also lack a nucleus.

Cells that do not have genetic material contained in a nucleus are known as prokaryotic cells. These cells are characterized by having their DNA located in the cytoplasm, and not enclosed within a nuclear membrane. Prokaryotes, such as bacteria and blue-green algae, consist of these types of cells. Although most eukaryotic cells have a nucleus, there are exceptions, like human red blood cells, which do not contain a nucleus when mature.

Prokaryotic cells are typically found in single-celled organisms, which are the most ancient and numerous forms of life on Earth. Unlike eukaryotic cells, prokaryotic cells lack a distinct nucleus and membrane-bound organelles. The lack of a nucleus means that the genetic information in prokaryotic cells is freely floating within the cell's cytoplasm, often in a circular DNA structure.

Additionally, it's interesting to note that certain eukaryotic cells, such as mature red blood cells in humans, also do not contain a nucleus. While this is not the norm for eukaryotic cells, it is an adaptation that allows these cells to better perform their function of oxygen transport.

O Horizon: Rich in organic matter.

A Horizon: Organic-mineral mix with organisms.

B Horizon: Clay and iron accumulation.

C Horizon: Partially weathered parent material.

R Horizon: Unweathered bedrock.

The question shows a diagram of soil horizons labeled O, A, B, C, and R. Below the diagram is an "Answer Bank" with descriptions of soil characteristics. To match the soil layers with their descriptions, we will use common knowledge about soil horizons:

1. **O Horizon**: This is the topmost layer, often rich in organic material. The description that fits this horizon is "almost exclusively composed of organic material."

2. **A Horizon**: This layer is known as the topsoil, where there is a mixture of organic material and minerals. It is typically darker than the layers below due to the organic matter. The fitting description is "a mixture of organic and mineral compounds where living organisms, such as earthworms, are concentrated."

3. **B Horizon**: Also known as the subsoil, this layer has accumulated minerals such as iron oxides from the layers above, which gives it a distinct coloration. The best match is "primarily parent material with accumulated clay and iron oxides that color the soil."

4. **C Horizon**: This layer consists of partially weathered parent material. Since it's less affected by the soil-forming processes, the description "partially weathered parent rock material that soil-forming processes have not changed" applies here.

5. **R Horizon**: This is the bedrock and the lowest of the soil layers. It is made up of large rock mass that has not been broken down or weathered significantly. The correct description is "large rock mass that has not been broken up or significantly weathered."

So the complete answer stepwise would be:

- O Horizon: almost exclusively composed of organic material.

- A Horizon: a mixture of organic and mineral compounds where living organisms, such as earthworms, are concentrated.

- B Horizon: primarily parent material with accumulated clay and iron oxides that color the soil.

- C Horizon: partially weathered parent rock material that soil-forming processes have not changed.

- R Horizon: large rock mass that has not been broken up or significantly weathered.

No, it is not correct to use same utensils for handling raw and the cooked food.

Cooking raw food an meat with the same utensil, can cause the transmission of meat particles on the hamburger. The hamburger is not cooked in a similar manner to the meat, so, the meat particles on the hamburger may remain uncooked, and may be they are contaminated with some pathogen, which can harm our body system. Hence, it is important to use different utensils for handling raw food and cooked food.

Final answer:

During fasting and starvation, the body initially uses glycogen for energy, then fatty acids, and eventually, through ketosis, produces ketone bodies as a primary fuel source, conserving proteins and muscle mass.

Explanation:

Throughout the different metabolic states, namely the absorptive (fed), postabsorptive (fasting), and starvation, the body utilizes various fuel sources. Initially, during the absorptive state, the body processes and stores excess glucose as glycogen in the liver and muscles. As we move into the postabsorptive state, the body begins to deplete glycogen stores and fatty acids are metabolized for fuel. When fasting continues and we reach the starvation metabolic state, the body initiates ketosis, where ketone bodies become a primary source of energy, particularly for the heart and other organs. This metabolic shift aids in conserving proteins, which are crucial for maintaining muscle and organ function. Over time, if energy demands persist and fat stores are exhausted, the body reluctantly catabolizes protein primarily from fast turnover organs, followed by muscle mass, to produce glucose through gluconeogenesis.

The statement that increase Energy Efficiency ultimately leads to lower cost is true. Energy Efficiency leads to both increased profitability and reduction of the CO2 emissions and thereby their environmental foot-print. Better recover and reuse of energy and easier maintenance are some of the things that lead do lower cost.

are some of the ways by which organisms reproduce asexually.

Explanation:

Asexual reproduction: where offspring are produced from the single parent and they receive the gene from only that parent. In asexual reproduction there is no fusion of gametes, and there no changes in the chromosomes numbers.

some of the ways by which organisms reproduce asexually are:

Similar to skeletal muscle, the membrane system involved in excitation-contraction coupling is structured similarly in cardiac muscle.

Sarcoplasmic reticulum is sparser, t-tubules are greater in diameter, SR creates connections with t-tubules, and cardiac muscle is composed of dyads as opposed to triads.

These are only a few of the differences, heart muscle contracts with precision to push blood into the circulatory system's channels.

Excitation and contraction coupling in cardiac muscle cells is similar to skeletal muscle cells by providing signals to both muscles.

Therefore, the banding arrangement of cardiac muscle is similar to that of skeletal muscle in that it is striated and divided into sarcomeres.

The organisms present in the ocean do not have to deal with the extremes of temperature or moisture. However, the main limiting factors in oceans are the availability of sunlight and concentration of dissolved oxygen and nutrients in ocean.

Limiting factors are the variables which cause a change in the process of photosynthesis. In case of oceans, Light is a limiting factor because an inadequate amount of light in the oceans leads to a decrease in the number of photosynthetic planktons. The photosynthetic planktons utilize light energy to form their food through the process of photosynthesis.

At lower intensities of light, it works as a limiting factor because an increase in light intensity can cause an increase in rate of photosynthesis. At higher intensities, further increase in light intensity does not increase the rate of photosynthesis here, light is not acting as a limiting factor.
