In looking at the relationship between hunger and conditions of the stomach it was found out that rats whose stomachs are removed continue to eat regularly.
What is Hunger?Hunger is referred to as the desire to want food in order to provide the required nutrients needed in the body.
Researchers studied the relationship between hunger and conditions of the stomach and found out that removal of the stomach of the rat didn't stop it from satisfying its hunger by eating regularly.

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%
True or False? Endurance training results in an increase in parasympathetic nervous activity and this allows for a reduced resting heart rate.
Answer:
Endurance training increases parasympathetic activity and decreases sympathetic activity in the human heart at rest. These two training-induced autonomic effects, coupled with a possible reduction in intrinsic heart rate, decrease resting heart rate.

Describe the characteristics of a vertebrate. Include an example.
Answer:
They have a backbone, most use legs,wings,or fins for movement.
Answer: Vertebrates are differentiated by having a vertebral column. As chordates, all vertebrates have a similar anatomy and morphology with the same qualifying characteristics , a dorsal hollow nerve cord, pharyngeal slits
Example
Vertebrates have a spine, or backbone, made of multiple disc-shaped bones called vertebrae. There are five classes of vertebrates which are: amphibians, fish, reptiles, birds, and mammals. Examples include frogs, tuna, snakes, parrots, and monkeys.

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.

increased birth rate
increased death rate
o increased immigration to foreign countries
O increase in the quality of medical care
Answer:
increased death rate
Explanation:
when people die population decreases the population of the country decreases
Answer: increased death rate
Explanation: increased birth rate is increasing the number of lives on earth increases immigration decreases the U.S.A'S total population but the total world population would be unaffected. Increase of quality medical care is a distractor because it has THE POTENTIAL to increase world population but people could still die so its not d. Which makes B; increased death rate our answer.
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.

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.

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.

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.
