Identify 3 or more other biotic and abiotic limiting resources that might drive competition within a single species.
Answers
Answer:
The 3 limiting factors that might drive competition within a single species is the food, availability of mates, disease, and shelter (biotic factors) and temperature, climate, sunlight, rainfall, natural disasters, and pollution (abiotic factors).
Explanation:
These factors limit the size of populations. As a population grows, there is more and more competition for the limited resources that Earth provides.
Biotic factors are living things that affect the ecosystem (like when we manually burn/chop down trees and destroy habitats of animals who used to live there).
Abiotic factors are non-living things (natural causes) that affect the ecosystem (like climate change causing the melting of glaciers and mass burning of trees (aka forest fire))

What form is DNA in during mitosis?
A. protein
B. ribosome
C. chromatin
D. chromosomes
Answers
Answer:
Chromosomes form is DNA in during mitosis.
Explanation:
In the context of the cell cycle, mitosis is the part of the division process in which the DNA of the cell's nucleus is split into two equal sets of chromosomes.
During mitosis, DNA is in the form of chromosomes, which is option D, as the chromosomes are condensed and highly coiled structures made up of DNA and associated proteins called histones.
During mitosis, a cell divides into two daughter cells that are genetically identical to the parent cell. Chromosomes are critical to this process because they carry the genetic information necessary for the formation of the new cells, and before mitosis begins, the chromatin (a complex of DNA and proteins) in the nucleus of the cell condenses into visible chromosomes. This condensation process involves the compaction of chromatin into a more compact and organized structure.

When studying animal behavior, the distribution of organisms within a choice chamber can be studied to identify animal preferences. 20 Isopods are placed in a 2-choice choice chamber. A cotton ball dampened with distilled water is placed in Chamber A; A dry cotton ball is placed in Chamber B. After 15 minutes 2 Isopods are located in Chamber B, and 18 isopods are found in Chamber A. Perform the chi-squared test to determine if the distribution of isopods is significant or due to random chance.a. chi-squared is 1.20, no it is not significant.
b. chi-squared is 8.42, no its not significant.c. chi-squared = 12.8, yes it is significant.d. chi-squared is 18.59, yes it is significant.
Answers
Answer:
The correct option is c. chi-squared = 12.8, yes it is significant.
Explanation:
Available data:
20 Isopods are placed in a 2-choice choice chamber. Different conditions were applied15 minutes later: 18 isopods are found in Chamber A and 2 Isopods are located in Chamber B.H₀= Individuals will be equally distributed
H₁ = Individuals will not be equally distributed.
Chi square= ∑ ((O-E)²/E)∑ is the sum of the terms
O are the Observed individuals: 2 in chamber B, and 18 in chamber A.
E are the Expected individuals: 10 in each chamber
X² = ∑ ((O-E)²/E) = ((2 - 10)²/10) + ((18 - 10)²/10) = 6.4 + 6.4 = 12.8
X² = 12.8
Freedom degrees = K – 1 = 2 - 1 = 1(K = Independent variables = dry cotton and wet cotton)
Significance level, 5% = 0.05 Table value/Critical value = 3.8412.8 > 3.84 meaning that the difference between the observed individuals and the expected individuals in each chamber is statistically significant. Not probably to occur by random chances.
There is enough evidence to reject the null hypothesis. The distribution of isopods is statistically significant.What happens in the thylakoid

(H)

Answers
The digestive process is divided into four steps: ingestion, chemical and mechanical food breakdown, nutrient absorption, and expulsion of indigestible food.
What does the digestive process entail?
The digestive process starts as soon as something is chewed. In order for food to pass more easily through your esophagus and into your stomach, saliva, a digestive juice produced by your salivary glands, moistens the food. The carbs in food also begin to be broken down by an enzyme found in saliva.
Motility, digestion, absorption, and secretion are the four fundamental functions of the digestive system. Our digestive system transforms our food into energy that we can use.
The digestive system's initial function is to take in food through the mouth. The "ingesting" procedure must take place before anything else can happen.
The complete question is:

According to the current body of scientific research, what effect does exercise have on an athlete’s vitamin requirements?
a. increases the need substantially, making vitamin supplementation necessary
b. increases the need substantially but supplementation not necessary
c. increases the need slightly but supplementation not necessary
d. increases the need slightly, making vitamin supplementation necessary
Answers
Option C: According to the current body of scientific research, exercise increases the need for vitamins slightly, but vitamin supplementation is not necessary.
Regular exercise and physical activity can impact various aspects of the body's metabolism and nutrient requirements, including vitamins. However, a well-balanced diet can typically provide enough vitamins to meet the increased needs brought on by activity.
Exercise may cause a minor increase in metabolic rate, oxidative stress, and energy expenditure. This may result in a higher turnover of several vitamins involved in generating energy and protecting against free radicals. However, research suggests that these increased vitamin requirements can typically be met through a varied and nutrient-dense diet without the need for vitamin supplementation.
It's crucial to remember that individual needs can change based on things like training volume and intensity, dietary requirements unique to the athlete, and any underlying medical issues.

Students recorded their heart rates in several situations. Which of the following data collected would illustrate a feedback response?
A)All students had a constant heart rate while they were at rest.
B)All of the student's heart rates are within a certain range.
C)The heart rates of males were higher on average than females.
D)Every student had an elevated heart rate during exercise.
Answers
Answer: Option D.
D)Every student had an elevated heart rate during exercise.
Explanation:
The students have elevated heart rates during exercise. This is because during exercise, muscles need 3 times or four times oxygen when you exert yourself. During exercise, the heart beat faster which make for quicker pulse so that more blood is pump out of you body. The heart beat both stronger and faster to increase cardiac output during exercise.
Cardiac output is stroke volume × heart rate.
Stroke volume is the amount of blood pumped by the heart.when the heart beats.
Heart rate is the number of times heart beats per minutes.

what would be the impact of a change in the dna strand from the original sequence of atgcgttcagcgatt to a mutated sequence of attcgttcagcgatt?
Answers
The mutation would result in a change from the amino acid methionine (ATG) to isoleucine (ATT) in the protein that is encoded by the mutated gene
A change in the DNA strand from the original sequence of ATGCGTTCAGCGATT to a mutated sequence of ATTCGTTCAGCGATT would result in a single nucleotide substitution, where the nucleotide ""A"" has been replaced by the nucleotide ""T"" in the first position. This type of mutation is called a point mutation or a substitution mutation. Since the genetic code is read in triplets of nucleotides (codons), a change in a single nucleotide can potentially change the amino acid sequence of the protein that is produced from the gene.
In this specific case, the mutation would result in a change from the amino acid methionine (ATG) to isoleucine (ATT) in the protein that is encoded by the mutated gene. Whether this change in amino acid sequence would have a significant impact on the function of the protein depends on the specific protein and the role that the amino acid plays in its structure and function.
