Two species of sea urchins adapted to live side by side on the sandy bottom of the sea floor. The two species appear to have the same diet—drift seaweeds and other bits of organic matter. They are able to adapt and to live in the same environment without competing with each other. How are they able to share habitat and food resources?
Two species of sea urchins live practically side-by-side in sandy bottoms. The two species appear to have the same diet: drift seaweeds and other bits of organic matter. They can live in the same environment without competing.
As it compels them to live in the same environmental surroundings so the characteristics of living nature also get developed as their current following situation that's helping them to get the same food & habitat.
Both species of sea urchins share the same habitat and food resources by separating their niches a little bit differently from one another.
What do you mean by Habitat?Habitat may be defined as a type of native environment for which a particular species is best adapted due to natural selection.
Competitive exclusion leads to the elimination of any one species until they do not share different niches.
Therefore, both species of sea urchins share the same habitat and food resources by separating their niches a little bit differently from one another.

What are some negative impacts of having this life cycle that might have contributed to a decline in the dragonfly population?
Answer:
Dragonflies are important for our environment.
Explanation:
Dragon flies belongs to the ancient family of insects. They are found on every parts of the world and have been from around 300 millions years ago. There are more than 5000 different species of them found in different parts of the world. Conserving dragonflies is important as they considered as a valuable environmental indicators.
Dragon flies are found in the areas where water is available and near grasslands. Their life cycle is an example of an incomplete metamorphosis. The dragon flies lays their eggs near the water or in the water. Dragon flies spends most of the life time as a nymph in the water where they turn into an adult and leave the water. The dragon flies rely on the aquatic ecosystems all through their life. Thus dragonflies are an important indicators of the environment and water quality.
Most of the life cycle of the dragon flies depend on the availability of water and its quality. Polluting water and destroying their habitat will result in the decline of the population of the dragon flies.

A certain microscopic single-celled organism is important to the dairy industry because when placed in milk, it consumes sugars in the milk and releases substances that react with the milk, adding flavor and thickening it. What kind of organism is this?
Answer:
I think its a type of bacteria but im not really sure, is there any choice options?
Explanation:
The dairy business depends on bacteria tiny single-celled organisms because, when added to milk, it consumes milk sugars and produce chemicals that react with the milk to taste and thicken it.
How dairy industry use bacteria?Temperature, pH, water activity, salt-in-moisture levels, and other factors all have a significant impact on how quickly bacteria thrive in dairy goods.
In order to acidify the cheese milk before and during the preparation of dairy foods, starter microorganisms must be used. Streptococcus thermophilus, Lactobacillus sp., and Lactococcus lactis.
However, dairy firms now often standardize the process by adding domesticated bacterial cultures, such as strains of Lactococcus lactis, Streptococcus thermophilus, and Lactobacillus sp. it can be done by naturally existing lactic acid bacteria in the milk.
Therefore, the dairy business depends on bacteria tiny single-celled organisms.

What are the three types of forests age and structure?
Answer:
Tropical rain forests grow around the equator in South America, Africa, and Southeast Asia, The temperature is stable year-round, around 27°C (60° Fahrenheit). As you can tell from the name, it rains a lot in these forests. Most tropical forests receive at least 200 cm (80 inches) of rain in a year. Tropical forests generally have a rainy and dry season. Temperate forests occur in the next latitude ring, in North America, northeastern Asia, and Europe, temperature ranges from -30 to 30°C (-22 to 86 F) and the forests receive 75-150 cm (30-60 in) of precipitation per year,

In this lab, you will simulate birds with three different beaks. After watching the birds feed, you will remove fruit to simulate a change in the environment. What question are you answering by doing this observation?
Answer:
How does a change in food resources model the type of beaks in birds?
Explanation:
We know that phenotype results from the interaction of the genotype and the environment. Any change in the environment produces a change in the phenotype of the animals. By performing this experiment, we probably want to know the influence of the environment on animals. In this particular example, we change a source of food by removing fruit (which would be acting as the independent variable of the experiment) and evaluate its effects on the birds´ beak (the dependent variable). Which of the three different beaks increases their frequencies by removing the fruit, and which one decreases its frequency.
So here, the absence of fruit is acting as a selective ecological pressure on birds. It is modeling birds´ beaks and adapting animals to feed on some other resource.
Change in food resources ---> Selective ecological pressure.Change in beaks frequency----> Adaptative response.Predict the genotypic ratios of the offspring from crossing the following:

Where do new alleles arise from?
Answer:
Gene mutations provide new alleles, making these mutations the ultimate source of variation. A gene mutation is an alteration in the DNA nucleotide sequence, producing an alternate sequence, termed an allele. Mutations occur at random, and can be beneficial, neutral, or harmful.
