You make two agar plates: one is a nutrient agar plate (plate A) that contains histidine and penicillin. The other is a glucose salts agar (plate B) that also contains penicillin. You inoculate a sample onto both plates using replica plating technique, incubate the plates, and compare the growth after 48 hours. There are 12 colonies on the nutrient agar plate and 11 colonies on the glucose salts medium. Which of the following statements is INCORRECT?

a. The colony that is missing from plate B is an auxotroph that cannot synthesize histidine.
b. The prototrophs are resistant to penicillin but the auxotrophs are sensitive to this antibiotic.
c. Prototrophs and auxotrophs in this experimeſit are resistant to penicillin.

Is it a good idea for humans colonize mars pls real answers :)

Answers

Answer:

I believe yes and no at the same time

Explanation:

If we do end up colonizing Mars, Earth could slowly get better as time goes on, but when we do colonize Mars, wont we just do the same thing we did to Earth?

Answer:

Yes it could be, here are the pros.. Colonizing Mars is one of the most promising backup plans for humanity . Mars is relatively close to our Earth . Colonizing Mars may become possible in just a few decades . Many celebrities support those plans . Many scientists advocate for this kind of backup plan . Extraction of additional natural resources . May help with the search for other life forms . We could learn as global human species . Humanity needs challenges to progress . Knowledge is power . May help to mitigate the overpopulation problem on Earth . Colonizing Mars is an image project . Future generations would be able to adapt quite quickly on Mars . May be a good long-term investment for institutional investors

But there are also some cons.. Colonizing Mars is extremely expensive . It takes a while to travel to Mars ; Lack of water may become a serious problem . Plenty of insecurity involved in this plan . Completely different living conditions . Humans need protective equipment before going outside . It’s freezing cold on Mars . Some people have to make the beginning . May not be justifiable from an ethical standpoint . Colonizing Mars may conflict with religion . Money can be better used to solve our problems on planet Earth . Some scientists believe that efficient live on Mars will not be possible . Quality of life on Mars would be much lower . Rather insecure food supply . Radiation may become a problem . Still unclear if living on Mars is sustainable . We would alter the balance in our universe . Colonizing Mars can be dangerous . Space exploration implies significant pollution . Other life forms may not be welcoming towards us humans . Short-term costs vs. long-term gains

In conclusion, no it would not be a good idea.

Maintaining high global biodiversity is important to provide ecosystem services to humans. Describe one cultural ecosystem service provided by diverse ecosystems.

Answers

Answer:

Ecosystem services of provision or supply

Explanation:

Ecosystem services

When talking about ecosystem services, we are referring to the benefits that ecosystems provide us. There are four types of ecosystem services:  

Provision or supply:

These are the products obtained by nature to be used or consumed, directly or with previous processing. Among them, we might mention food, clear freshwater, fertile soils, geotic materials (such as salt), raw materials (that can be used for clothing, construction), renewable fuels, biochemical compounds, pharmacological/medicinal resources, among others. Provisioning service has an impact on the economy, as many of these products are used to commercialize.  

Regulation:

Refers to ecological processes that improve life. Among others, we might mention climate regulation, CO² absorption, water purification, air purification, erosion control, natural disaster avoidance such as flooding, soil fertility maintenance, waste recycling, pests/plagues control, etc.  

Cultural:

Refers to not the material benefits. Ecosystems also provide a recreational place or area to spend time, to learn, provide a spiritual/religious space, are a source of inspiration. Ecosystems are considered to be cultural patrimony. Ecosystems are the source of scientific knowledge.

Support:

Involves ecological processes needed for the production of the other three previously mentioned services. There are five different support services:

→ Soil formation

→ Photosynthesis

→ Primary production

→ Nutrients cycles

→ Water cycle

Under certain circumstances, regulation services can also be considered support services.

Support service affects human beings indirectly, or direct but causing an effect in a long-term period.

Answer:

Uniform dispersion pattern.

Explanation:

Uniform dispersion pattern is a type of dispersion pattern in which resources are present in abundant quantity as well as evenly distributed with little interaction within individuals. Due to abundant quantity of resources , the population of organisms increases that leads to more population of individuals in the ecosystem. Due to abundant amount of resources, there is less competition as well as interaction between individuals that are present at that time.

* The bacterial colonies grown without glucose don’t have capsules around their cells - OBSERVATION

* Bacterial growth in the glucose environment increased rapidly and then stopped after some time - OBSERVATION

* Increased glucose may lead to capsule formation in bacteria - HYPOTHESIS

Explanation:

In an experiment, a HYPOTHESIS is a predictive and testable statement that aims to answer a scientific question while an observation is made based on the results obtained.

According to this question, Annie wants to study the effect of glucose on bacterial colonies. She conducted the experiment by growing two colonies of bacteria - one with glucose present in the environment and one in an environment without glucose. Based on this experiment, the following statements are categorized as:

- Glucose may cause an increase in bacterial growth is a HYPOTHESIS

- The bacterial colonies grown without glucose don’t have capsules around their cells is an OBSERVATION

- Bacterial growth in the glucose environment increased rapidly and then stopped after some time is an OBSERVATION

- Increased glucose may lead to capsule formation in bacteria is a HYPOTHESIS

d. people overfertilize crops and lawns
e. algae overgrow, become overcrowded,

f. excess nitrogen and phosphorus leads

Answers

The overgrowth of microscopic algae is an algal bloom. The correct order is people overfertilize, excess nutrients transported by rain to nearby water bodies, excess nitrogen and phosphorus leads to algal bloom, algae overgrow, become overcrowded, decomposers that break down dead algae take in oxygen for cellular respiration and finally lack of oxygen causes death of fish and other aquatic life.

What are algal bloom?

The overgrowth of microscopic algae or algae-like bacteria in fresh or salt, waters is referred to as algal bloom.

Depending on the type that cause it, an algal bloom may produce bad-smelling, foam, or a paint-like slick.

According to the given scenario, the correct order will be:

People overfertilize crops and lawns.Excess nutrients from fertilizer are transported by rain to nearby water bodies.Excess nitrogen and phosphorus leads to overgrowth of algaeAlgae overgrow, become overcrowded, and die.Decomposers that break down dead algae take in oxygen for cellular respiration.Lack of oxygen causes fish and other aquatic organisms to die.

Thus, this was the correct order of events to show the cause-and-effect relationships that leads to algal bloom.

A biologist grows bacterial cultures to see if there is a relationship between time and growth rate. Here are the data. Which hypothesis test would you use to see if there a relationship between growth rates and time

Answers

Answer:

Direct relationship.

Explanation:

There is direct relationship between growth rates and time which means growth rate of organism increases with the passage of time. Direct relationship means if one increases the other automatically increases and if one decreases, the other also decreases. The growth of bacteria becomes double when more time passes and vice versa. After every 20 minutes, the population of bacteria becomes double.
