If the order of expression of the highlighted Hox gene was disrupted, moved, or changed by mutation, it would cause the replacement of a part of the body by a structure whose normal location would correspond to another site.
The differentiation of the limbs occurs during embryogenesis, thanks to the action of a group of specialized genes, called Hox gene.
This gene is involved in the developmental program that determines the location of organs along the anteroposterior axis.
These subdivide the embryo along the head-tail axis into cell fields with different developmental potentials, which will transform into limbs and other structures.
Hox gene mutations thus show that there are genes that can control the different regions of the genome that determine the structures of an organism.
These produce considerable anatomical transformations that, in the case of the fly, can consist of:
The formation of wings instead of halteres or legs.An extra pair of wings where small appendages called stabilizers would normally be.Therefore, we can conclude that if the order of expression of the Hox gene was disrupted, moved, or changed by mutation, it would cause the structures normally found in one body segment of the fly to be replaced by found in another segment.

b. Osmosis
c. Facilitated diffusion
d. Diffusion
Answers
Diffusion is described as the flow of individual molecules through a semipermeable barrier from a region of higher concentration to a region of lower concentration. Therefore (D) is the correct option.
What are different types of diffusion ?
Diffusion is the flow of molecules down the concentration gradient. Various types of diffusions are :
Facilitated Diffusion: The passive transport of molecules along the concentration gradient. It is a selective process, meaning that only specific molecules and ions can pass through the membrane.
Osmosis: A process where solvent molecules move from a less concentrated solution to a more concentrated one by tending to pass across a semipermeable membrane.
Therefore, option (D) includes all other processes.

HOW DO HURRICANES CAUSE FLOODING?
There are a few ways a hurricane can create a high risk for flooding:
Storm Surge
According to the National Hurricane Center (NHC), a storm surge is one of the biggest threats during a hurricane (or even a tropical storm). A storm surge takes place when strong winds from a hurricane push ocean water ashore. This creates an unexpected rise in the seawater level, above the predicted tide, notes the NHC.
While a storm surge is a threat to property, it can also put you at risk for drowning, the NHC says. This is because floodwaters can rise rapidly and with little warning.
Storm Tide
A storm tide happens when a storm surge takes place during high tide, says the NHC. A storm tide is the total height of seawater that comes ashore (calculated by adding the normal tide and storm surge water levels). A storm tide can result in water elevations that are much higher than a storm surge alone — in some instances, 20 feet or more, according to the NHC.
Heavy Rainfall
Torrential rains stemming from a hurricane or tropical storm can cause rivers, lakes and streams to flood within minutes or hours, says the National Weather Service (NWS). A slow-moving storm can also increase the risk of flooding, notes the NWS. This is because slow-moving storms allow rainfall to inundate the same area for an extended period of time.
HOW TO PREPARE FOR HURRICANE-INDUCED FLOODING
Beyond knowing the connection between hurricanes and flooding, it’s a good idea to educate yourself on some safety measures. That way, you can take steps to help protect yourself, your family and your home before a hurricane arrives. Here are some tips from the American Red Cross to consider:
Prepare Your Property
Clean out gutters and downspouts.
Install water alarms.
Safeguard important documents by making digital backups (and store the originals in a secure location).
Consider purchasing a flood insurance policy, which helps cover the cost of replacing or repairing your home and belongings after a flood. A flood insurance policy can take up to 30 days to go into effect, so it’s important to be proactive.
Prepare Your Family
Devise an evacuation plan that includes potential routes out of the area and shelter locations.
Create an emergency kit to take with you in case of an evacuation (include items like bottled water, food and batteries).
SAFETY TIPS DURING A HURRICANE OR FLOOD
When a hurricane is approaching, it’s important to know what you can do to help you and your family stay safe. Here are some tips from Ready.gov to keep in mind:
Monitor local radio and TV stations for weather reports.
Follow instructions and evacuation orders from local authorities.
Close any storm shutters on your home and stay away from windows.
Seek shelter in a windowless room on the lowest level of your home (one that’s least likely to flood).
Move to higher ground if a flood occurs (but avoid closed attics, as you may become trapped by rising water).
If you are instructed to evacuate, do so immediately, Ready.gov says. But, be sure to avoid driving or walking through floodwater. It only takes 6 inches of moving water to knock you down, or 12 inches of water to sweep a car away, adds Ready.gov.
Being prepared and putting some protective measures in place ahead of a hurricane or flood may help you stay safe if one strikes. Consider taking some steps to protect your home and your family now, and remember these tips in case a hurricane or flood occurs in your area.

Answers
Answer:
The process by which leukocytes squeeze through adjacent cells in a blood vessel wall is called emigration
The answer is B
Leukocytes are the white blood cells responsible for protection from infections. The process by which leukocytes squeeze through adjacent cells in blood vessels is called emigration. Thus, the correct option is B.
What are leukocytes?Leukocytes are also known as white blood cells. These cells are responsible for the defense mechanism of the body. Leukocytes protect the body from infections as these are part of the body's immune system.
Leukocytes migration is essential for the ability of WBCs to react to the inflammatory stimuli at various locations within the body. These cells cannot swim due to lack of locomotory organelles. So, for the movement these cells use emigration. These process helps them to move to the site of infection to kill the pathogen and reduce the infection.
Therefore, the correct option is B.

5 Clear Mark for Review Sacculina carcini is a barnacle that attaches to the underside of the green crab. The barnacle finds a hole in the green crab's exoskeleton, then uses microscopic hairs to feed on nutrients from the green crab's blood. The barnacle also lays its eggs in the green crab reproductive system, which sterilizes the green crab. Which term describes the role of S. carcini in this relationship?
Answers
Answer:
S. carcini is a parasitic barnacle species
Explanation:
Parasitism: In this case, one of the species is beneficiated, while the other suffers a consequence, reducing its fitness. These interactions are mostly about nutrition, although there might be other benefits too. Some parasite species might coexist with their host, while some others might get them ill to the point of causing death. Parasitic attacks might be very nocive, and even though they are not lethal in a short period of time, they might slowly kill the host.
Parasitic species consume part of the host, but not the whole body. They develop an intimate relationship with their host.
The Host increases the fitness of the parasite speciesThe parasitic species decreases the fitness of the host.By taking the nutrients from the green crab's blood and sterilizing it, the barnacle causes a decrease in the fitness of the crab. The crab becomes weaker and its survival chances decrease, and they have no opportunity to reproduce. Meanwhile, the barnacle gets stronger and reproduces normally.

Explanation:
Its the only one that benefits from warm weather.
Species that are better adapted to warmer weather would be most likely to survive if the temperature in an area gradually increases over time. Hence, option A is correct.
What is adaptation?The biological process through which organisms adapt to brand-new surroundings or alterations in their current environments is known as adaptation.
Another type of adaptation is behavioral, which modifies how an organism reacts to its surroundings. The structural adaptations made by some plants to survive in hot, dry deserts are one illustration of this. Succulent plants, which store water in their short, thick stems and leaves, have evolved to thrive in this environment.
