Why does geographic isolation cause speciation?
A. It increases gene flow between populations.
B. It allows two populations to evolve separately.
C. It increases interbreeding between populations.
D. It causes adaptive radiation.

Answers

Answer 1
Answer:
B. It allows two populations to evolve separately.



Explanation:
Geographic isolation is theorized to have catalyzed the formation of new species. Let’s say groups B and D of a bird species get separated by something, and they can’t cross between to interbreed or exchange alleles.

We describe this as no gene flow, which is the opposite of choices A and C. Because of this, they may diverge if given enough time due to the difference in environmental pressures, because they’re now in different environments.

D is incorrect because it doesn’t apply.

help me in my hw landslide can be prevented by terrace farming why​

Answers

Answer:

Reducing the intensity of runoff.

Explanation:

Terrace farming prevent landslides and erosion to occur by reducing the intensity of runoff. This farming also reduce the risk of drought due to raising the moisture content in the soil and allowing water to slowly infiltrate into the soil. Due to terrace farming, the runoff water moves very slowly which causes less erosion of the soil as well as reduces the intensity of water flow which causes more infiltration.

The CT reveals several issues with the cranial structure, one of which might be in the cribriform plate but the image isn't well defined. What non-invasive test can you do to test if the cribriform plate is severely damaged? Why?

Answers

The non-invasive test that can be used to test if the cribriform plate is severely damaged is called the pledget study.

CRIBRIFORM PLATE is the part of the ethmoid bone that forms the nasal cavity.

The olfactory nerve which is part of the cranial nerves passes through the small opening found in the cribriform plate.

A damage to the cribriform plate leads to cerebrospinal fluid (CSF) leak which usually comes out from the nose and ears.

Therefore to test if the cribriform plate is severely damaged, the pledget study is performed.

Pledget study is a non-invasive method of diagnosing a CSF leak.

To perform this test,

Cotton pads called Pledgets are placed in the nostrils.If the leaking fluid contains CSF it will be detected.

The presence of CSF shows that there is damage to the cribriform plate.

This method is non invasive because it doesn't require the breaking or opening of any part of the body.

The sodium-potassium pump does not do which of the following actions?
-Moves sodium molecules against their concentration gradient into the cell
using ATP.
-Moves sodium molecules against their concentration gradient out of the cell
using ATP.
-Maintains the cell's physiological needs by establishing an electrochemical
gradient.
-Moves potassium molecules against their concentration gradient into the cell
using ATP.

Answers

The sodium-potassium pump does not allow the movement of sodium molecules against their concentration gradient into the cell  with the use of ATP molecules.

In sodium-potassium pump, the sodium moves outside the cell whereas potassium moves inside the cell with the help of using ATP molecules. The sodium-potassium pump maintains the gradient of higher concentration of sodium extracellularly means outside the cell and a higher level of potassium intracellularly means inside the cell. This process is done only in the presence of ATP molecules that provides a force for the movement of sodium and potassium so we can conclude that no movement of sodium occur inside the cell in the sodium-potassium pump.

https://brainly.com/question/24347696

Answer: Moves sodium molecules against their concentration gradient INTO the cell using ATP.

Explanation:

The sodium-potassium pump moves sodium molecules against their concentration gradient out of the cell and moves potassium molecules against their concentration gradient into the cell. It also helps to regulate internal physiological needs through gradients. However, it doesn’t move sodium ions into the cell—that occurs through passive transport.

In biological systems, there are several membrane transport systems responsible for the passage of ions like Na+ and K+.

a. True
b. False

Answers

Answer:

The correct answer is: a. True.

Explanation:

There are several membrane transport systems responsible for the passage of ions like Na+ and K+.

Cell membranes are semipermeable, which means they can regulate which molecules may and cannot flow through them. Some molecules may simply drift in and out of a cell (this is called simple diffusion), while others require specific structures to enter and exit (this type of diffusion is called facilitated diffusion), and still, others require an energy boost to pass the cell membrane (this is known as active transport).

Both simple diffusion and facilitated diffusion are types of passive transport: they happen without the energy boost that ATP gives, unlike active transport.

In passive transport, molecules follow their chemical gradients and travel through the most concentrated compartment to the less concentrated one to equal the concentrations. In active transport, on the other hand, the cell makes an effort to enter or exit ions against their chemical gradients and this is done particularly to maintain said gradients (they are required for the correct functioning of the cell).

Sodium and Potassium are two of the most important ions when it comes to maintaining these gradients: sodium is very concentrated in the outside of the cells (the extracellular compartment), while potassium is highly concentrated in the intracellular compartment. These differences in concentrations are maintained thanks to the Na+/K+ pump, a form of active transport. Apart from the Na+/K+ pump, these ions go through the membrane through passive transport as well, without requiring energy.

The correct energy flow during aerobic respiration is ATP, Glucose, and cells. Thus, the correct option is B.

What is Aerobic respiration?

Aerobic respiration may be defined as the process of conversion of glucose into carbon dioxide, water, and energy via the intermediate product of pyruvate in presence of air.

The release of energy in aerobic respiration is found to be greater as compared to anaerobic respiration.

This released energy is immediately used to synthesize a molecule called ATP via glucose that fuels the cells for metabolic activities.

Answers

Answer:

The correct answer is - NAD needed to keep glycolysis going is not being recycled so the entire process is shut down and no ATP is produced

Explanation:

Alcohol dehydrogenase plays role in metabolizing the bulk of ethanol consumed as part of the diet and their activities contribute to the rate of ethanol elimination from the body.

Inhibitor of this zinc enzyme prevents it to perform its function which results in NADH generated during anaerobic conditions glycolysis cannot be recycled back to NAD+, So the ATP production pf anaerobic condition through glycolysis cannot be maintained.

Answers

Answer: Air enters through the nose (and sometimes the mouth), moves through the nasal cavity, the pharynx, the larynx, enters the trachea, moves through the bronchi and bronchioles till the alveoli.

Explanation:The pathway of air in the respiratory system starts with the external organs of the nose and mouth.

Nose: Air is inhaled through the nostrils (and sometimes through the mouth) where it is filtered by the hairs and cilia to remove dust particles and moistened. The nasal cavity also moderates the temperature of the inhaled air.

Pharynx: This is a common passage for food, water, and air. It leads from both the nose and the mouth and leads to both the trachea (windpipe) and the oesophagus (foodpipe).

Larynx: This is the voice box situated just over the trachea and has a flap called the epiglottis which closes during swallowing to prevent food from entering the trachea and opens during breathing.

Trachea: Air now enters the windpipe which is situated behind the sternum (breastbone) and between the two lungs.

Bronchus: From the trachea, two bronchi (one bronchus for each lung) enter the lungs and divide and subdivide into secondary and tertiary bronchi, getting narrower as they proceed into the lung.

Bronchioles: The tertiary bronchi branch into fine tubules called bronchioles, the last passageways for air.

Alveoli:. Air ends its pathway in the alveoli (sing. alveolus) which are tiny sacs with very fine singe-celled walls. These alveoli are surrounded by capillaries that connect the pulmonary arteries and veins and that enable transfer of oxygen and carbon dioxide.
