Did the seized tusk come from one of the recently slaughtered elephants? ________ What evidence supports your finding?

Answers

Complete question:

Now you are ready for your first major assignment. Your colleagues are investigating a newly seized tusk and wonder if the tusk is from a recently discovered crime where 10 elephants from the same population were found dead with their tusks removed. The genotype of the seized tusk for five short tandem repeat (STR) loci is shown in Table 1. Allele names for each of the STR loci correspond to their size in base pairs (bp). Table 2 lists the genotypes of the same five STR loci for 10 recently slaughtered elephants.

Did the seized tusk come from one of the recently slaughtered elephants? ________ What evidence supports your finding?

Note: You will find the tables in the attached files

Answer:  

Probably the seized tusk belonged to elephant number eight.

Explanation:

Potentially, the seized tusk might belong to individual number eight. In both the tusk and the elephant, the genetic analysis resulted in the same-sized alleles for each locus.

FH19: 193 193FH60: 147 147FH67:97 103FH71: 62 62FH129: 152 160

The fact that, among the ten individuals of the population, only the individual number 8 matches the tusk for SRT loci, suggests that it belongs to the animal, but it does not ensure it 100%.

Answers

Answer:

Its A

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.

If the temperature in an area gradually increases over time, species that are better adapted to warmer weather would be most likely to survive. Therefore, option A is correct.

Hurricanes create high winds and heavy downpours that can cause intense flooding in certain areas. It’s important to understand your flood risk if you live in a hurricane-prone area so you can take steps to be better prepared in case one strikes. Here’s a look at different types of flood hazards that stem from hurricanes and some tips to help you stay safe.

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

One big way to tell a difference is that DNA is double stranded, in the shape of a double helix, while RNA is single stranded. (This is why RNA can leave the nucleus and DNA cannot) There are also factors that affect the difference like how DNA contains thymine, and when RNA makes copies of it, it becomes uracil.

The process by which leukocytes squeeze through adjacent cells in a blood vessel
wall is called?
a) leukocytosis
b) emigration
c) cytoplasmic extending
d) positive chemotaxis

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.

Similarities Between Photosynthesis And Cellular Respiration

Similarities ...

→ Both involve in production of energy

→ Both involve the exchange of gases

→ Both the process takes place in cell organelle which was considered as endosymbiotic organism. They are chloroplast and Mitochondria, Photosynthesis takes place in Chloroplast where as respiration takes place in mitochondria.

→ At critical condition both have alternate pathway.

Differences...

→Photosynthesis takes place in chloroplast, where as respiration takes place in mitochondria.

→Photosynthesis involve production of carbohydrate and respiration involve breaking of carbohydrate.

→ Photosynthesis occur only during presence of sunlight where as respiration occurs all the time.

→ In photosynthesis process Oxygen is released where as in respiration Oxygen is utilised.

These are the main differences between Photosynthesis and respiration.
