one time within 2 days my house was filled with fruit flies
Answer:
Bacteria
Explanation:
Bacteria reproduce most quickly . Fruit flies can go from the egg to sexual maturity in 3 weeks while bacteria can reproduce once they are "born" and can do so multiple times a day, while fruit flies can reproduce if mature once every day about.
Finches and humans obviously have much slower rates of reproduction.

Is it a good idea for humans colonize mars pls real 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.

Biodiversity is the variety of life habiting the earth's ecosystem with numerous genetics and ecosystem levels. Protecting lands will increase biodiversity.
What is biodiversity?Biodiversity is the variety of living organisms living together in an area, that works together in an ecosystem to support life and maintain the population.
Biodiversity is affected by the temperature, food, reproduction rate, and habitat. Protecting the habitats will increase biodiversity.
Changes in temperature will affect biodiversity negatively, and decreasing food and reproduction ability will decrease the population of the biodiversity.
Therefore, option D. protecting lands can increase biodiversity.

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
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.

C
Explanation:
What do you predict would happen if hydrogen bonds formed between any two nitrogenous bases in DNA ?
Answer:
I believe replication would not be possible, therefore the DNA would cease to help recreate cells which are essential to the human body.
Explanation:
This question by far is highly interesting, in fact it is very controversial too. However, with the sudden beginning of an actual hydrogen bond forming within nitrogenous bases, then replication would not be possible. This is so because replication relies only on nitrogenous bases rather than hydrogenous bonds. Therefore, resulting in a possible defect in the process of replicating to occur. However, if possible, I believe there might be even a chance of a mutation to occur, yet that is highly rare given the stance that the DNA molecule would not be able to pretty much do anything if that were to occur.
1. Place these events in the correct order to show
the cause-and-effect relationships that lead
to algae blooms.
a. decomposers that break down dead
algae take in oxygen for cellular
respiration
b. lack of oxygen causes fish and other
aquatic organisms to die
c. excess nutrients from fertilizer are
transported by rain to nearby bodies of
water
d. people overfertilize crops and lawns
e. algae overgrow, become overcrowded,
and die
f. excess nitrogen and phosphorus leads

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.

In fruit Flies a white eyed female is crossed with a red eyed male. What are the changes the offspring will be a white eyed male?
Answer:
the chances of the offspring having white eyes is 50%
Explanation:
i used a punnet square to calculate the output:)
Answer:
25%
Explanation:
There's a 50% chance of the offspring being male & 50% chance female. The genotypes must be co-dominant otherwise their question doesn't give enough information to get an anwser. Also a 50/50 chance of red/white, so added together a 25% chance.

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

6. What regulatory processes would your body use if you were trapped by a blizzard in an unheated, uninsulated cabin in the woods (or in a heat wave with no air conditioning)
Answer:
Shivering and sweating.
Explanation:
A prolonged exposure to extreme cold environment would activate the brain's heat-gain center. Your brain's heat-gain center causes shivering in order to increase our muscle contraction which leads to warming of our body. Increase sweating is the regulatory processes our body use if it experience very high temperature. In order to regulate internal temperature of body, our body remove water which takes up heat with itself to lower th internal temperature.

What is tRNA?A form of RNA molecule called transfer ribonucleic acid (tRNA) aids in the translation of a messenger RNA (mRNA) sequence into a protein.
Translation, which creates a protein from an mRNA molecule, uses tRNAs at particular locations on the ribosome. A protein's amino acid composition is determined by codons, which are three-nucleotide mRNA sequences.
Every codon corresponds to a distinct amino acid, and every codon is accepted by a particular tRNA. The three hairpin loops that make up the tRNA molecule's characteristic folded structure give it the appearance of a three-leafed clover.
