Answer:

In areas of Africa where malaria is prevalent the number of sickle cell cases remains consistent generation after generation. ---- support the hypothesis.

In Canada the incident of sickle cell anemia has been increasing in the population. -----  contradicts the hypothesis.

Explanation:

In areas of Africa where malaria is widespread the number of sickle cell cases remains consistent generation after generation while on the other hand, In Canada the incident of sickle cell anemia are lower in the population because of environmental condition is not good for increase in malarial disease. In Africa, the environment is suitable for the mosquitoes that causes malaria so there is high increase of sickle cell anemia in the population.

The texture of the lung is spongy and porous, with a network of air sacs and tiny blood vessels.

On the other hand, the texture of a liver lobe is smooth and dense, with many lobules that are made up of hepatocytes, bile ducts, and blood vessels. The texture of the lung is essential for its function, which is to allow gas exchange to occur efficiently. The porous texture provides a large surface area for the diffusion of oxygen from the air into the bloodstream and carbon dioxide out of the bloodstream and into the air. The spongy texture also allows the lung to expand and contract with each breath, ensuring that fresh air is continuously brought into the lungs.
Similarly, the texture of the liver lobe is vital for its functions, which include filtering and processing blood from the digestive system, producing bile, and storing glucose. The dense texture of the liver lobe allows it to filter and process large amounts of blood efficiently. The lobular structure of the liver lobe also ensures that hepatocytes and other liver cells are close to the blood vessels, facilitating their functions.

Lyme disease is caused by bacteria that are transmitted to humans through the bite of infected black-legged ticks, which can become active when the temperature rises above freezing.

Tick-borne diseases, including Lyme disease, are on the rise, with more than 100 cases in some states of the US. Lyme disease cases have spread in many parts of the United States, so what three environmental conditions could be the cause?The three environmental conditions that could cause Lyme Disease to affect more people over a larger portion of the United States are as follows:1. Shorter winters due to a warming climate allow for a longer period of tick activity.2. An increase in infected ticks due to decreased range of the white-footed mouse.

3. Warmer temperatures in northern regions of the country allow for an extended range for the tick.Therefore, options D, C, and E are correct.

Explanation:

During meiosis, the Y chromosome undergoes recombination with the X chromosome, which may help preserve some functions and prevent total degeneration of the Y chromosome.

During meiosis, the process of cell division that produces gametes (sperm and eggs), recombination occurs between homologous chromosomes. Homologous chromosomes are pairs of chromosomes that carry the same genes, one inherited from each parent. However, the Y chromosome is unique in that it does not have a matching pair of chromosomes like the X chromosome does.

To prevent the complete degeneration of the Y chromosome over time, it has evolved a mechanism called pseudoautosomal regions (PARs). PARs are small regions of homology between the X and Y chromosomes that allow for recombination to occur during meiosis. This recombination between the X and Y chromosomes helps to exchange genetic material and can preserve some functional genes on the Y chromosome.

By undergoing recombination with the X chromosome, the Y chromosome can acquire new genetic variation and prevent the accumulation of harmful mutations. This recombination process helps to maintain the integrity and functionality of the Y chromosome, ensuring the preservation of essential genetic information.

If a human embryo develops with a mutation that prevents smooth muscle from developing in the body and it survives to birth, the bodily functions that will be most heavily affected by this mutation are: Digestive system functions. So, option B is  accurate.

Smooth muscle plays a crucial role in the digestive system, as it lines the walls of various organs such as the stomach, intestines, and blood vessels. It is responsible for rhythmic contractions, called peristalsis, that propel food through the digestive tract and facilitate the absorption of nutrients. Without functioning smooth muscle, the ability of the digestive system to properly move and process food would be significantly impaired, leading to digestive complications and potential nutrient absorption issues.

While smooth muscle is also involved in other bodily functions, such as muscular movement (c) and blood vessel constriction/dilation, the digestive system functions would likely be the most heavily affected in this scenario. The heart (a) primarily consists of cardiac muscle rather than smooth muscle, and bone functions (d) are primarily regulated by other types of cells and tissues.

Numerous substances make up the ECM, such as collagen fibers, proteoglycans, fibronectins, laminin, etc., which is a complex network of proteins and carbohydrates.

There are many ways that cells and the ECM communicate with one another. Particular elements of the ECM, including collagen, fibronectin, and laminin, are bound by integrin receptors on the cell surface. Cell adhesion, migration, proliferation, and differentiation are just a few of the biological activities that are regulated by this binding's intracellular signaling pathways.

Additionally, ECM components are secreted and broken down by cells, altering the ECM's composition and structure and changing how cells behave. Additionally, growth factors and other signaling molecules that might affect cell behavior and tissue formation can be sequestered and released by ECM components.

The synthesis of nucleoside arises from the binding of the nitrogenous base to the deoxyribose sugar via N-glycosidic linkage.

Answer:  h = 2.125

Explanation:

Simplifying

10h + 6h = 34

Combine like terms: 10h + 6h = 16h

16h = 34

Solving

16h = 34

Solving for variable 'h'.

Move all terms containing h to the left, all other terms to the right.

Divide each side by '16'.

h = 2.125

Simplifying

Answer:

The answer is h = 4.

Explanation:

1) Subtract 10 from both sides.

\(6h = 34 - 10\)

2) Simplify 34 - 10 to 24.

\(6h = 24\)

3) Divide both sides by 6.

\(h = \frac{24}{6} \)

4) Simplify 24/6 to 4.

\(h = 4\)

therefor, the answer is h = 4.

The water moves from the soil through the cells of plants and finally reaches the atmosphere via transpiration. The resistance factors of this process are air, humidity, light intensity, temperature, and transpiration. Casparian strips are important for their impermeable nature for water movement.

The movement of water starts when the root uptakes water from the soil. The water first enters the growing root tip and then enters the root hairs. The water will move the root using three different pathways such as apoplastic, transmembrane, and symplastic pathways. Once this water crosses these pathways, the centers the cortex and crosses the endodermis having a Casparian strip. Then, water enters the xylem cells which are subject to long-distance transport. The water then vascular bundle and distribute in the epidermal and mesophyll cells. It is drawn into plant cell walls and is moved to the atmosphere in the form of water vapor via stomata. The resistance that affects this pathway is air, humidity, light intensity, temperature, and transpiration.

Casparian strips are impermeable substances that are found in the endodermal cells of plant roots. They form a barrier against the apoplastic flux and force the ions to pass through the selectively permeable membrane to the cytoplasm. This thus forms positive hydrostatic pressure and prevents the movement of toxic and pathogens.
