Ind. variable: salt added/not added. Dep. variable: water boiling over. Controlled variables: pot size, number of water cups, high heat. Exp. group: Water to which salt was added. Control group: Water with no salt on it.

This is the variable changed on porpose by the researcher to study how these changes affect the dependent variable response, and hence, the experiment results.

This is the one directly affected by the changes provoked by the independent variable. It will change following the changes in the independent variable.

Since several variables might influence the results, the researcher must keep constant all the other variables that might influence the results. The reason is to make sure the only one affecting the dependent variable response is the independent one.

In the exposed example,

Goal: to test if salt keeps water from boiling over fast.

Independent variable: added salt

Dependent variable: water boiling over

Controlled variables: pot size, number of water cups, high heat.

Experimental group: Water to which salt was added

Control group: Water with no salt on it.

The process by which plants use light energy to transform water, carbon dioxide, and high-energy carbohydrates like sugars and starches into oxygen is Photosynthesis.

Photosynthesis is the process by which phototrophs transform light energy into chemical energy that is later utilized to power cellular processes. Sugars, made from carbon dioxide and water, are used to store chemical energy.

According to the definition of photosynthesis, photosynthetic pigments like chlorophyll a, chlorophyll b, carotene, and xanthophyll are used exclusively in the chloroplasts. Photosynthesis is a method that all green plants and some other autotrophic organisms use to make nutrients out of carbon dioxide, water, and sunlight. Oxygen is produced as a byproduct of photosynthesis.

The true statement for an activator is that interaction with an inducer can cause the activator to bind DNA.

In gene regulation, an activator is a protein that enhances the transcription of a gene by binding to specific DNA sequences known as enhancer elements. Activators play a crucial role in initiating gene expression by promoting the binding of RNA polymerase to the promoter region.

The other statements are not true for an activator. An activator does not bind to the operator sequence in the promoter (the operator is typically bound by a repressor protein). It does not come off the DNA in response to a signal molecule, as its binding is necessary for gene activation. An activator does not block the binding of RNA polymerase; instead, it facilitates the binding and initiation of transcription.

However, interaction with an inducer can cause the activator to bind DNA. Inducers are small molecules that can bind to the activator protein, inducing a conformational change that enables the activator to bind to specific DNA sequences and enhance gene expression. This interaction between the activator and the inducer is a key mechanism in the regulation of gene expression.

The correct answer is Genetic information is stored in the nucleus as DNA molecules.

The nucleus is a membrane-enclosed organelle, determined in maximum eukaryotic cells, which shops the genetic material (DNA). Most DNA is placed withinside the cellular nucleus (in which it's far known as nuclear DNA), however, a small quantity of DNA also can be determined withinside the mitochondria (in which it's far known as mitochondrial DNA or mtDNA).

The genetic information saved in an organism's DNA consists of the commands for all of the proteins the organism will ever synthesize. In eukaryotes, DNA is contained withinside the nucleus.

Explanation:

The answer is 800 mice survive the heat wave, and the new allele frequencies for the population are 0 for the dominant allele (B) and 1 for the recessive allele (b).

A total of 200 mice with black fur die from heat stroke, so the remaining mice are those with white fur. To find the number of surviving mice, we need to subtract the number of black-furred mice from the total number of mice.

Number of surviving mice = Total number of mice - Number of black-furred mice
Number of surviving mice = 1000 - 200
Number of surviving mice = 800

The new allele frequencies for the population will be calculated based on the number of surviving mice. Since all of the black-furred mice died, the frequency of the dominant allele (B) will decrease, while the frequency of the recessive allele (b) will increase.

Frequency of B = Number of B alleles / Total number of alleles
Frequency of B = 0 / (800 x 2)
Frequency of B = 0

Frequency of b = Number of b alleles / Total number of alleles
Frequency of b = (800 x 2) / (800 x 2)
Frequency of b = 1
So, the new allele frequencies for the population are 0 for the dominant allele (B) and 1 for the recessive allele (b).

The DNA of the cells' chromosomes is copied during S phase of the cell cycle.

The full form of DNA is deoxyribonucleic acid. It is a molecule that contains genetic information and instructions for the development and function of living organisms. S-phase or synthesis phase is a stage of interphase, which is the cell cycle's most prolonged phase.

DNA replication occurs in this stage, which means that the cell's DNA is duplicated to prepare for mitosis, which happens during the next stage, the G2 phase.

S phase also ensures that the DNA is correctly copied before being separated during cell division. Chromosome duplication happens in the S-phase of interphase.

The most common local and global effects of burning petroleum in car engines are smog and global warming.

Global effects refer to the various impacts that the actions of individuals, businesses, and governments have on the environment and society at large. Global effects can include changes to the climate, water cycle, biodiversity, food production, and other natural systems.

Smog is a form of air pollution created by the reaction of sunlight with emissions from car exhausts. The emissions contain nitrogen oxides, volatile organic compounds, and carbon monoxide which react with sunlight to create smog. This smog, which can cause respiratory problems, is especially common in heavily populated areas with high traffic. Global warming is caused by the release of carbon dioxide and other greenhouse gases into the atmosphere from burning petroleum. These gases trap heat in the atmosphere, leading to an increase in global temperatures.

Pain relievers, anti-inflammatories, antivirals, and antihistamines all manage: inflammation.

An indication of inflammation may occur when a wound grows, gets red, and aches. The body's immune system reacts to an irritant by causing inflammation, to put it very simply. A splinter in the finger or other foreign item, such as a bacterium, might possibly be the source of the irritation.

Aulus Cornelius Celsus, a Roman physician, wrote about the four primary symptoms of inflammation in the first century AD. These symptoms include redness (Latin rubor), heat (calor), swelling (tumor), and pain (dolor).

Science has shown that persistent, low-grade inflammation can become a silent killer that fuels type 2 diabetes, cancer, cardiovascular disease, and other illnesses.

The third difference between plants and animals from the lessons learnt so far in this class is that:

Plants can manufacture their food by themselves while animals cannot but depend on organisms for food.

Plants are able to synthesize their food by themselves through photosynthesis due to the presence of chlorophyll in their chloroplasts. Animals cannot produce food on their own simply because they lack the green pigment chlorophyll and so, they depend on other organisms for food.

In conclusion, it can be deduced that plants are autotrophs while animals are heterotrophs.
