Your kidneys have an important effect on blood pressure. The kidneys controls plasma volume by controlling how much _____________________.

Answers

The kidneys control plasma volume by controlling how much Na and water are reabsorbed.  

The juxtaglomerular apparatus is a structure formed by the distal convoluted tubule and the glomerular afferent arteriole which regulate blood pressure and filtration. The components of the apparatus are macula densa which detects Na concentration and juxtaglomerular cells which sense the blood pressure. When blood pressure and Na decrease, the juxtaglomerular cells then release an enzyme called renin. Renin converts angiotensinogen into angiotensin I, then angiotensin I is converted to angiotensin II which causes blood vessels to contract (elevate the blood pressure). Angiotensin II also stimulates the adrenal gland to secrete aldosterone which stimulates more Na and water reabsorption (also elevates the blood pressure).

Answer:

C. Water a person excretes

Explanation:

The kidneys controls the amount of water a person excretes which effects the blood pressure by controlling the volume of plasma.

Suppose a non-native species of beetle was introduced into a forest. How would you know if the beetle was becoming an invasive species

Answers

Final answer:

To identify if a beetle is becoming an invasive species, look for rapid population growth, harm to the ecosystem, or outcompetition of native species. Citizen reports and early response are key for controlling the spread. Signs include damage to trees, die-offs, and reduced insect diversity.

Explanation:

To determine if a non-native beetle is becoming an invasive species in a forest, several indicators can be observed. An invasive species often has rapid population growth, outcompetes native species for resources, and causes harm to the environment, economy, or human health. Early detection and rapid response are crucial for controlling invasive species. When citizens like the individual in Chicago who noticed the Asian longhorned beetle become informed and proactive, they can significantly aid in the monitoring and control efforts by reporting sightings to appropriate authorities.

Common signs of an invasive beetle might include noticeable damage to tree bark, leaves, or fruit, due to feeding or breeding activities, a sudden die-off of native trees, or an absence of previous insect diversity due to the invasive beetle outcompeting native species. Effective strategies like engaging the public through education, consistent monitoring, and establishing an early warning system are vital for successful management and potentially eradicating an invasive species before it becomes too widespread.

-Chris

Answer:

Aquifers

Explanation:

Groundwater is an important source of water. It is the water present in the deeper layers of soil below the water table. Some of the important sources of groundwater are rainfall, rivers, ponds, etc. When it pours, water goes down in the soil layers to fill the spaces present below the ground. When the groundwater is accumulated between the hard rock layer, it becomes aquifer. The aquifers serve as a source of fresh water as the water present in them can be pumped out using techniques such as tube wells.

Answers

This arrest of division is an example of Density-dependent inhibition. Density dependent inhibition is the process where crowded cells stop dividing; the number of cells in an area force competition for nutrients, space, and growth factors, therefore, when cells are crowded, they get signals to stop dividing. In density dependent inhibition, when density is high there is no cell division and when the density is low cells divide.

Modern h. sapiens differ from the archaic form in that moderns have

Answers

Modern H. sapiens differ from the archaic form in that moderns have a high, vertical forehead, a mental eminene; and lack occipital bun. Modern homo sapiens have distinguishing features such as they have a short base, a high braincase, back of the skull is rounded and indicates a reduction in the neck muscles, face is reasonably small with a projecting nose bone among other features that makes them different from the other sapiens. 

Final answer:

Modern Homo sapiens are distinguished from archaic forms by their larger, more complex brains, smaller faces, jaws, and front teeth, and changes in skull morphology such as less pronounced brow ridges and the development of a prominent chin. They also have a more elaborate tool kit, including the blade tool industry.

Explanation:

Differences between Modern Homo sapiens and Archaic Homo sapiens:

The evolutionary journey from archaic Homo species to modern Homo sapiens has been marked by significant changes in physical anatomy and behavior. Modern humans are biologically distinct from their archaic predecessors in a number of ways. One of the most notable physical differences is the size and structure of the brain. Modern H. sapiens have a much larger brain capacity, averaging around 1,200 to 1,400 cubic centimeters, just like some archaic forms, but with a more developed prefrontal cortex and smaller face, jaws, and front teeth. Another distinctive characteristic of modern humans is their skull morphology, which generally includes a rounder skull, less prominent brow ridges, and a prominent chin, unlike their archaic counterparts who had thicker skulls and more pronounced brow ridges.

Furthermore, the behavioral changes that accompany these physical evolutions are substantial. Modern humans demonstrate a significant leap in tool-making abilities, transitioning from the Mousterian prepared-core flake tools to a more sophisticated blade tool industry. This advancement allowed the crafting of tools from a wider variety of materials including bone, antler, and ivory, which facilitated the development of a rich material culture in the Upper Paleolithic period. Additionally, modern H. sapiens displayed advanced cognitive functions and social behaviors, leading some researchers to speculate about their use of language and complex social structures.

chromosomal mutation definition

Answers

When the nitrogenous base in a chromosome gene changes

Answer:

Chromosomal mutation is the change in the structure or number of chromosome.

Explanation:

Chromosomal mutation simply refers to a change in the structure of chromosomes.

The structure of chromosome changes as a result of deletion, duplication, inversion or translocation.

Deletion refers to the loss of certain segments of the chromosome.

Duplication of segments of the chromosome leads to repetition of some genes.

Inversion is the change in the order of genes on a chromosome.

Translocation involves the insertion of chromosomal segments into a non-homologous chromosome.

Chromosome number can change as a result of non-disjunction during meiosis. This may result in aneuploidic or polyploidic chromosomal conditions

All insertion sequences (is elements) contain two features that are essential for their movement. what are these two elements?

Answers

These two elements are transposase and terminal repeats. Transposase enzyme binds to the end of a transposon and catalyzes the movement of the transposon to another part of the genome by a cut and paste mechanism or replicative transposition mechanism. Terminal repeats are identical sequences which repeats hundreds or thousands of times, found at the end of proviral DNA formed by reverse transcription of retroviral RNA. They are used by viruses to insert genetic material into the host genomes.

Insertion sequences (IS elements) are equipped with inverted repeats and a transposase enzyme, both critical for their ability to move within the genome.

All insertion sequences (IS elements) contain two essential features that are essential for their movement: inverted repeats and a transposase enzyme. The inverted repeats are short DNA sequences found at both ends of the IS element that are necessary for the transposase to recognize and cut the DNA for movement. The transposase is an enzyme encoded by the IS element itself that catalyzes the excision and integration of the IS element into a new location within the genome.

Although the open ocean is among the least productive ecosystems, it contributes greatly to the overall productivity of the biosphere. How can this situation be explained?

Answers

Final answer:

The open ocean contributes greatly to the biosphere's productivity due to the massive scale of ocean ecosystems and the vital role of phytoplankton in oxygen production through photosynthesis. The ocean upwelling also redistributes nutrients, enhancing productivity.

Explanation:

Although the open ocean is among the least productive ecosystems, it plays a significant role in global productivity, largely due to the extent of ocean ecosystems which encompass over 70% of the Earth's surface. The ocean's vastness houses numerous species, ranging from large marine mammals to the tiniest of organisms, such as phytoplankton.

Phytoplankton are crucial for the biosphere as they release over 50% of the oxygen produced on Earth through photosynthesis. This process not only contributes to the oxygen we breathe but also forms the foundation of the marine food web. The neritic zone, with its high biodiversity and productivity, plays a significant role in supporting marine life and fisheries. However, it's the sheer scale of the open ocean that allows its contribution to overall biosphere productivity.

Moreover, phenomena such as ocean upwelling help redistribute nutrients from the ocean floor back to surface waters, aiding in the productivity of these ecosystems. Therefore, the open ocean's significant contribution to Earth's productivity can be explained by the large area it covers, the oxygen production by phytoplankton, and the mechanisms that redistribute nutrients within these aquatic systems.
