How many atoms are there in 25 grams of calcium
Answer:
The molecular weight of calcium carbonate is 100 g per mole. 25 g of calcium carbonate corresponds to 0.25mole. 1 molecule of calcium carbonate contains three oxygen atoms. Thus, 0.25 mole of calcium carbonate will contain 0.75 moles of oxygen atoms which is equal to 0.75×6.02×10^23=4.51×10^23 oxygen atoms.

they choose to incinerate or burn their trash. What is a risk we take when burning trash? (4a)
air pollution
water pollution
polluting the ground water
thermal (temperature) pollution
Air pollution is the a risk we take when burning trash or garbage.
Risk of burning garbageBurning trash can leads to health problems. The toxic chemicals that are released during burning of garbage such as nitrogen oxides, sulfur dioxide, volatile organic chemicals and polycyclic organic matter.
These gases go to the atmosphere and pollute the air so we can conclude that air pollution is the a risk we take when burning trash or garbage.

Define ecological competition
Ecological Competition is most typically considered the interaction of individuals that vie for a common resource that is in limited supply, but more generally can be defined as the direct or indirect interaction of organisms that leads to a change in fitness when the organisms share the same resource.
Answer:
Ecological Competition is an interaction between organisms or species in which both require a resource that is in limited supply. Competition lowers the fitness of both organisms involved, since the presence of one of the organisms always reduces the amount of the resource available to the other.
PLEASE HELP!!!!!!!!! WILL GIVE 30 POINTS AND MARK BRAINLIEST Explain why a food web is a more realistic model of energy flow than a food chain.
Answer:
because food web can contain like all foods food chain is each individual different chains
Explanation:
its like the same as animals
Answer:
Food chains only show one path by which energy can move through an ecosystem. Because most organisms eat a variety of things, they are part of many food chains. A food web shows the interconnected food chains in an ecosystem and the multiple paths through which energy can move, which is why it is a more realistic model for showing energy flow.

Can you guys help me?
1. One of the basic conditions for natural selection to occur is that there must be variability within a species. What variability was present in the population of utensil birds?
2. Before the terrible drought, which beak types gathered the most food items?
3. After the terrible drought, which beak type was most successful?
4. Over time, if drought conditions continue, what would you expect to happen to the number of birds with each of the 4 types of beaks in the population? Be specific as to which ones might increase, decrease, or stay the same.
5. As the individuals of the species change over time, the whole species may begin to look very ddifferent. If these birds become isolated from other populations, it may even become a completely different species. What is the name of this process called?
6. In this experiment, why did we do four trials for each type of food instead of just one?
7. Why did we focus on the class average data instead of the individual group averages?
8. Did your group get trivial or significant differences between your trials for the spoon beak? What most likely caused these differences?
Here my graphs; by the way don't worry about the forks! because my group dind't have any.
Based on natural selection and the data provided, it was observed that birds with the spoon beak type were most successful in obtaining food both before and after the drought.
What is natural selection?Natural selection is the process by which organisms that are better suited for survival in an environment are selected to survive and reproduce.
Natural selection depends on variation among species.
Considering the table:
1. There was variation in the beak type of the birds.
2. Before the drought, the toothpick beak type and spoon beak type gathered the most most food.
3. After the terrible drought, the spoon beak type was most successful.
4. If the drought conditions continues;
The toothpick beak type will decreaseThe spoon beak type will stay the samethe fork beak type will decreasethe knife beak type will decrease5. The process by which If the birds become isolated from other populations they become a completely different species is called evolution.
6. Having repeated trials helps the reduce the possibility of chance occurrence in the results obtained.
7. The class average data will give a truer picture of the effects of drought on bird feeding because of the larger number of sample.
Also, it will help to eliminate individual group errors and identify outliers.
8. There were no significant differences between your trials for the spoon beak.

During maturation of the oocyte, what happens to the chromosomes as a result of meiosis?.
Answer:
The cell becomes haploid, with 23 single chromosomes.
Explanation:
Hope This Helps.
The process of meiosis, a form of cell division that decreases the number of chromosomes in the cell from two sets to one set, occurs as the egg matures.
The creation of gametes, which are reproductive cells with just one pair of chromosomes, depends on this process. The main oocyte, which has two sets of chromosomes, is formed at the start of meiosis. The two sets of chromosomes align into homologous pairs during meiosis I, cross across, and combine to create new genetic combinations.
Four daughter cells are created as a result of this process, and each one of them has a set of chromosomes made up of the original two sets. The four meiosis II genes are dividing to become double.

A particular molecule is 45% Cytosine. What percentage of the molecule is Thymine?
Answer:
55%
Explanation:
if the whole molecule is 100%, then cytosine plus thymine is 100%
cytosine + thymine = 100%
45% + thymine = 100%
thymine = 100% - 45%
thymine = 55%

The rabbit population would increase causing the wolf population to increase.
The rabbit population would decrease causing the wolf population to increase.
The rabbit population would decrease causing the wolf population to decrease.
The rabbit population would increase causing the wolf population to decrease.
Answer: C) The rabbit population would decrease causing the wolf population to decrease.
Explanation: If there is no food for the rabbits, then they die, and because there are no rabbits, there is no food for the wolves so they die, simple.
