Sanitizer is a chemical or fluid that kills germs on the skin and on objects. Sanitizing something is cleaning it by eliminating dirt or eradicating germs on it.
Hand sanitizer, also known as hand antiseptic, handrub, or hand rub, is an agent that is applied to the hands in order to remove common germs (disease-causing organisms).
IPA, propanol, and ethanol are the alcohols utilized. Chlorohexidine gluconate, for example, is found in alcohol-free hand sanitizers.

how have humans changed the carbon cycle
Answer:
Human activities have a tremendous impact on the carbon cycle. Burning fossil fuels, changing land use, and using limestone to make concrete all transfer significant quantities of carbon into the atmosphere. ... This extra carbon dioxide is lowering the ocean's pH, through a process called ocean acidification.

When environmental conditions change, selection can cause a change in the distribution of phenotypes of that species. Which of the following trends would provide evidence of disruptive selection in response to environmental change?
A shift in a population's frequency curve from an intermediate phenotype to an extreme phenotype
A shift toward equal distribution of all phenotype frequencies, including intermediate and extreme phenotypes
An increase in the frequency of extreme phenotypes and a decrease in the frequency of intermediate phenotypes
An increase in the frequency of intermediate phenotypes and a decrease in the frequency of extreme phenotypes
Answer:
One of the extreme phenotypes has the highest fitness. The bell curve shifts towards the more fit phenotype.
so I think w ould say the second one
Explanation:
Answer:
An increase in the frequency of extreme phenotypes and a decrease in the frequency of intermediate phenotypes

#CarryOnLearning#NoToPlagirismHow does the body plan and anatomy enable the chordate to perform essential functions it needs to survive?
Answer: Keep in mind invertebrates are those who have exoskeletons (outside skeleton) or are hydrostatic (no skeleton). This make up 95% of all animals for example an ant or sponge. For a sponge, all it has is tissues that enable it to allow water to flow out the tops.

Ollie runs 40 meters in 5 seconds. How far could she run in 60 seconds?
Answer:
60 seconds would be 480 meters
Explanation:
we can find the answer by using the method of distribution, but first take the 60 seconds and divide by 5 seconds and we'll get 12 then multiply that by 40 meters to get 480 meters and since we divided 60 seconds by 5 the was how we figured out what to multiply the 40 meters to.
The human immune system detects the presence of pathogens using pattern recognition receptor molecules that bind to common components of pathogens, such as peptidoglycan polymers in cell walls and the flagellin protein of bacterial flagella, known as pathogen-associated molecular patterns, or PAMPs. These receptors are effective becauseGroup of answer choicesthey detect only human immune molecules.they result in rapid evolution of the host immune system.they recognize evolutionarily conserved molecules that are structurally essential to the various bacteria that use them.PAMPs evolve more quickly than other pathogen molecules.
They recognize evolutionarily conserved molecules that are structurally essential to the various bacteria that use them.
What are Pattern recognition receptor molecules?Pattern recognition receptor molecules detect pathogen-associated molecular patterns (PAMPs), which are structurally conserved components of pathogens such as bacteria, viruses, and fungi. These molecules are essential for the survival and function of the pathogen, and are not found in the host's cells.
By recognizing PAMPs, the immune system can quickly identify and respond to a wide range of potential pathogens, without needing to recognize every individual pathogen separately. Therefore, the receptors are effective because they recognize evolutionarily conserved molecules that are structurally essential to the various bacteria that use them.

Where do maple trees get their energy and Matter at the beginning of spring
Answer:
From the stored sugar inside the stem and branches.
Explanation:
The maple trees get their energy at the beginning of spring from the sugar that is stored in the stem and branches because there is no leaves present at that time. Leaves produces glucose during photosynthesis process but in the winter season, the maple tree losses all its leaves so when the spring season comes and the leaves begin to sprout, the maple trees need energy so it used the sugar that is stored in its branches and stem for the generation of energy.

How can an offspring have a trait that neither parent
has?
Answer: How might it be possible for you to show a trait when neither of your parents show the same trait. It can be carried to you when the chromosomes combine even if the parents don't possess the same trait It can skip and be dominant for you so you would be able to see it in your genetic make up.
Explanation:
Determine whether each statement correctly describes the myocardial action potential and the pacemaker potential. 1. Because the pacemaker potential occurs during systole, it can also be called systolic potential. (Click to select) 2. The pacemaker potential is the relatively slow, spontaneous depolarization in the SA node. (Click to select) 3. Myocardial cells produce their own action potentials after being stimulated by action potentials originating in the SA node. (Click to select) 4. Myocardial action potentials are characterized by a spike and then slow depolarization. (Click to select)
Answer:
1. False
2. True
3. True
4. False
Explanation:
In mammals, the contraction of the heart muscle is caused by pacemaker cells localized within the sinoatrial (SA) node. These cells rhythmically generate slow electrically-induced action potentials due to their slow rate of depolarization. The pacemaker cells generate the action potentials that propagate through the heart and trigger the contraction of myocyte cells (i.e., myocytes simply conduct the action potential waves). The slow depolarization of pacemaker cells occurs during diastole, i.e., during the period of relaxation of the heart muscle.
