What are the conditions required for natural selection? Check all that apply.
Final answer:
Natural selection occurs when there is variation of traits among individuals, competition for resources, and overproduction of offspring. These conditions enable individuals with advantageous traits to have a better chance of surviving and reproducing, leading to evolutionary changes in the population over generations.
Explanation:
Conditions Required for Natural Selection
Natural selection is a critical mechanism in evolutionary biology. According to Darwin, populations evolve through natural selection when specific conditions are met. These conditions include:
Variation of traits among individuals within a population.Competition for limited resources.Production of more offspring than can survive (overproduction).Natural selection favors individuals who are better adapted to their environment, meaning those with traits that give them a survival or reproductive advantage are more likely to pass on their genes to the next generation. This condition-based process gradually leads to population-wide changes over generations.
The concept of genetic equilibrium, such as in the Hardy-Weinberg equilibrium, describes a situation where a population's genetic makeup is not changing over time. This occurs when there is:
No mutationNo migrationA very large population sizeRandom matingNo natural selectionIn reality, natural selection disrupts genetic equilibrium by ensuring that those with advantageous traits have a higher chance of survival and reproduction than those without such traits, thereby changing the genetic makeup of the population over time.

etc.?
A
during the 19 trimester
B.
during the 3rd trimester
C.

Answer:
during the 1st trimester
Explanation:
Just did it on study island
Cellular differentiation begins in the third week after fertilization, where unspecialized stem cells become various specialized cell types. The correct option seems to be missing which is the third week after fertilization.
Cells begin the differentiation process early in embryonic development. Specifically, cellular differentiation starts during the third week after fertilization when the embryo starts to form various specialized cells. This is when stem cells become specialized into cell types such as muscle cells, nerve cells, and reproductive cells. As part of this process, certain genes are activated, indicating the cells' transition into different forms with unique structures and functions suitable for their roles in the body.
In order for altruism to be possible, there must be __________ to conceive of another’s emotional state, and __________, which allows you to see a situation from another viewpoint.
A.
perspective . . . empathy
B.
understanding . . . empathy
C.
empathy . . . perspective
D.
trust . . . perspective
Answer:
C
Explanation:
For the first blank, we need to find a word whose definition is essentially "to conceive of another's emotional state", and for the second blank, we need to find a word whose definition is "allows you to see a situation from another viewpoint".
Let's define all the words given:
- "perspective": one's way of viewing something - basically, your viewpoint of a certain issue
- "empathy": being able to understand another's emotions
- "understanding": comprehending another's situation or the issue at hand
- "trust": the assurance that you can rely on a person when you're in need
Out of all these, only "empathy" fits the first blank and only "perspective" fits the second. So, C is correct.
Answer: C.
Explanation:
Definitions for the set of words:
Perspective: A point of view
Understanding: the ability to comprehend.
Empathy: the ability to understand another's feelings.
Trust: faith in another person or thing.
Although understanding fits the first blank, empathy is more descriptive of emotions in particular.
Perspective in the context of emotions allows you to feel from a different point of view.
Trust and understanding are somewhat unrelated to the question posed.
Which of the following best describes alcoholic fermentation?
A. Alcoholic fermentation is the final step of cellular respiration.
.
B. In the absence of oxygen, cells release ATP by breaking down
ethanol into glucose and water.
C. In the absence of oxygen, cells release ATP by breaking down
glucose into ethanol and carbon dioxide.
O D. Alcoholic fermentation is the first step of cellular respiration.
Answer:
I would say C, based on this research. Not 100% sure tho
Explanation:
Ethanol fermentation, also called alcoholic fermentation, is a biological process which converts sugars such as glucose, fructose, and sucrose into cellular energy, producing ethanol and carbon dioxide as by-product
Alcoholic fermentation begins with the breakdown of sugars by yeasts to form pyruvate molecules, which is also known as glycolysis. Glycolysis of a glucose molecule produces two molecules of pyruvic acid. The two molecules of pyruvic acid are then reduced to two molecules of ethanol and 2CO2
C. In the absence of oxygen, cells release ATP by breaking down
glucose into ethanol and carbon dioxide.
What is ethanol fermentation used for?Ethanol fermentation is used in the production of alcoholic beverages. Lactic acid fermentation is used to flavor or preserve dairy and vegetables. Lactic acid fermentation also occurs in muscle cells under strenuous activity.
What are the two stages of ethanol fermentation?Alcohol fermentation has two steps: glycolysis and NADH regeneration. During glycolysis, one glucose molecule is converted to two pyruvate molecules, producing two net ATP and two NADH.

A scientist follows this procedure to test whether plants have been performing photosynthesis. Place Plant X in a dark closet and Plant Y on a sunny windowsill. Wait several days, then remove a leaf from each plant. Boil leaves in alcohol to remove the chlorophyll. Add a chemical indicator that detects sugars. (Dark purple = sugars are present; dark orange = sugars are not present) What results will the scientist most likely obtain when placing drops of the indicator on the leaves?
1: Plant X: dark purple Plant Y: dark purple
2: Plant X: dark orange Plant Y: dark purple
3: Plant X: dark orange Plant Y: dark orange
4: Plant X: dark purple Plant Y: dark orange
Answer:
2. Plant X: dark orange, Plant Y: dark purple
Explanation:
Two plants; plants X and Y were used in this experiment. Photosynthesis is the process by which green plants synthesize their food (sugar). Plants make use of the energy they capture from sunlight via their Chlorophyll pigment to power the photosynthetic process. Plants cannot perform the process of photosynthesis in the absence of sunlight i.e. No sunlight, No photosynthesis and ultimately no sugar.
In the case of this experiment, Plant X was placed in a dark closet while Plant Y was placed on a sunny windowsill. Due to the absence of light in the dark closet, plant X will be unable to photosynthesize and produce sugars while plant Y, due to its exposure to ample sunlight, would be able to produce sugars in its leaves via photosynthesis.
Therefore, since dark purple = sugars are present and dark orange = sugars are not present when tested with a chemical indicator, plant X's leaf will give a dark orange color because it produced no sugars in its leaves as it was unable to photosynthesize. Plant Y's leaf will give a dark purple color because it produced sugar in its leaves as a result of photosynthesis.
Plant X, which was placed in a dark closet, will not have performed photosynthesis and will not have produced sugars. Plant Y, which was placed on a sunny windowsill, will have performed photosynthesis and will have produced sugars. Therefore, the leaves of Plant X will turn dark orange and the leaves of Plant Y will turn dark purple when the chemical indicator is applied. Hence option 2 is correct.
The leaves of a plant that has been performing photosynthesis will contain sugars. These sugars can be detected using a chemical indicator that changes color in the presence of sugars.
In the experiment described, the scientist is using a chemical indicator that turns dark purple in the presence of sugars. Therefore, the leaves of Plant Y, which have been performing photosynthesis and contain sugars, will turn dark purple when the chemical indicator is applied.
The leaves of Plant X, which have not been performing photosynthesis and do not contain sugars, will turn dark orange when the chemical indicator is applied.
Therefore, option 2 is correct.

Explanation:
It eats the vegetation so less food means they have less chance of survival
Final answer:
A decrease in the population of vegetation (option A) would most directly cause a decrease in the population of tundra swans by undermining the support of the food web.
Explanation:
The question asks which changes in the food web would cause a decrease in the population of tundra swans. Considering the given options:
A decrease in the population of vegetation could potentially lead to a decrease in the population of tundra swans, as the vegetation is likely a primary food source for organisms that tundra swans feed on.An increase in the population of benthic invertebrates, which might be part of the tundra swan's diet, would not cause a decrease in swan population.An increase in the population of wading birds may lead to increased competition for food resources with the tundra swans.A decrease in the population of osprey, which might be a predator or a competitor, could have complex effects, but is less likely to directly cause a decrease in tundra swan populations compared to the other factors.The most accurate answer is option A: A decrease in the population of vegetation could lead to a decrease in the population of tundra swans, by reducing the overall food web support.

A female guinea pig homozygous dominant for black fur color is mated with a male homozygous for white fur color. In a litter of eight offspring, there would probably be ____. * 5 points 8 black guinea pigs. 4 black and 4 white guinea pigs 2 black, 4 gray, and 2 white guinea pigs 8 white guinea pigs.
Answer:
8 black guinea pigs
Explanation:
We're given that the black fur color is the dominant trait, meaning that this problem deals with complete dominance. In complete dominance, having just one allele is enough to express a certain phenotype. So let's say the female guinea pig has the genotype BB for homozygous black. The male would be bb since he's homozygous white, and the color white is recessive. Cross this and you get the genotypes Bb. But remember that even having one dominant allele will be sufficient to express the dominant phenotype. So all guinea pigs shall be black in fur color.

(To clarify it can be two words but that’s how many letters are in it and there’s a “i” on the third letter)
The process of asexual reproduction where a reproductive cell is enveloped by a hard outer casing is spore formation. Regarding the female reproductive system, fertilization generally happens in the Fallopian tube.
Explanation:The type of asexual reproduction where a specialized reproductive cell is surrounded by a hard outer casing is called spore formation. This is a common method of asexual reproduction in fungi, algae, and some plants. In this scenario, the parent organism produces spores - small, lightweight cells capable of growing into new organisms without the need for fertilization.
The location in the female reproductive system where fertilization occurs is known as the Fallopian tube. The Fallopian tubes connect the ovaries to the uterus. After ovulation, the oocyte (egg) travels into the Fallopian tube where it can be fertilized by sperm.
