Answer:
150cm
Explanation:
There are 100cm in 1m so we can multiply to found how many centimeters we need.
9 * 100 = 900cm
Now we can subtract to find how many more centimeters we needs.
900 - 750 = 150cm

Enzymes and substrate fit together at the active site to form a lock and key mechansim. This means
a) if they don't fit, it is the wrong substrate or the enzyme is denatured.
b) substrates work on enzymes, allowing them be be denatured.
c) the shape and size of the enzymes does not matter.
d) enzymes are not specific and work on a variety of substrates.
Answer:
the answer is option b hope you understand
The lock and key mechanism of enzyme and substrate means that if they don't fit, it is the wrong substrate or the enzyme is denatured.
WHAT IS AN ENZYME?
An enzyme is a protein substance that regulates biochemical activities in living cells by acting as a catalyst. Enzymes act on substrates but they do not get changed during the process. This means that enzymes can be used over and over again. Enzymes are substrate-specific i.e. they act on specific substrates. The lock and key model explains the mechanism of action of enzymes. Enzymes attach to substrate at their active sites and act on them to form products.The lock and key model explains that if enzyme and substrate don't fit, it is either the wrong substrate or the enzyme is denatured.

Consider an experiment in which subjects are given a pill to test its effectiveness in reducing the duration of a cold. Which of the following is the best way to treat the control group.
A. Give the control group two pills instead of one.
B. Do nothing with the control group.
C. Give the control group a pill that looks like the test pill but does nothing
Answer:
c.
Explanation:
(comment if you need an explenation and I'll give it)
Give the control group a pill that looks like the test pill but does nothing is the best way to treat the control group. Option C is correct.
The best way to treat the control group in this experiment is option C: give the control group a placebo pill that looks like the test pill but does not contain any active ingredients. Here's why:
Ensuring Validity: A control group is used to establish a baseline for comparison. By giving the control group a placebo pill that looks identical to the test pill, researchers ensure that both groups experience the same psychological and physical conditions except for the presence of the active ingredient. This helps eliminate potential bias and confounding variables that could affect the results.
Blinding: Giving the control group a placebo maintains blinding, where participants do not know whether they are receiving the active treatment or the placebo. This prevents participants' expectations or beliefs from influencing the outcomes, enhancing the experiment's validity.
Placebo Effect: The placebo pill accounts for the placebo effect, a psychological phenomenon where participants experience improvements in their condition due to their belief in the treatment's effectiveness. By giving the control group a placebo, researchers can assess whether the test pill's effects are genuinely due to the active ingredient or influenced by participants' perceptions.
Ethical Considerations: It's important to provide some form of treatment to the control group to ensure they are not harmed or misled. Giving them a placebo pill with no therapeutic effect is an ethical way to include them in the study while minimizing potential risks.
Overall, using a placebo that mimics the appearance of the test pill ensures a controlled and rigorous experiment, where the effects of the active ingredient can be accurately evaluated. This approach maintains scientific integrity, valid comparisons, and ethical considerations.

A DNA segment is changed from AATTAG to AAATAG. What type of mutation is this and what is its effect on the genetic variation of a population?
A.
The mutation is a substitution which causes a decrease in the genetic variation of a population.
B.
The mutation is an insertion which causes a decrease in the genetic variation of a population.
C.
The mutation is an insertion which causes an increase in the genetic variation of a population.
D.
The mutation is a substitution which causes an increase in genetic variation of a population.
The mutation from AATTAG to AAATAG is a substitution which causes an increase in genetic variation of a population.
MUTATION:
Mutation refers to any change in the nucleotide sequence of DNA molecule. Mutation can be of different types depending on how it occurs. A substitution mutation is that in which one or more nucleotide base is replaced by another in the sequence. In this question, an original sequence of DNA is given as AATTAG. It was mutated to AAATAG via the replacement of 'T' with 'A'. This means that it is a substitution mutation. However, this mutation will cause an increase in the genetic variation i.e. difference in a population.Learn more at: https://brainly.com/question/21220597?referrer=searchResults

Describe the roles of the soil organisms in the carbon cycle
Carbon cycle is a biogeochemical cycle by which carbon is exchanged among the different components of the Earth.
Carbon cycle along with the Nitrogen cycle and the Water cycle, comprises a sequence of events that are key to make Earth capable of sustaining life.
It describes the movement of carbon as it is recycled and reused throughout the biosphere, as well as long-term processes of carbon sequestration to and release from carbon sinks.
The terrestrial carbon cycle is dominated by the balance between photosynthesis and respiration.
Carbon is transferred from the atmosphere to soil via ‘carbon-fixing’ autotrophic organisms, mainly photosynthesizing plants and also photo- and chemoautotrophic microbes that synthesize atmospheric carbon dioxide (CO2) into organic material.
Fixed carbon is then returned to the atmosphere by a variety of different pathways that account for the respiration of both autotrophic and heterotrophic organisms.
The reverse route includes decomposition of organic material by ‘organic carbon-consuming’ heterotrophic microorganisms that utilize the carbon of either plant, animal or microbial origin as a substrate for metabolism, retaining some carbon in their biomass and releasing the rest as metabolites or as CO2 back to the atmosphere.
What is the role of soil organisms in the Carbon Cycle?Soil Organisms or Microbes are critical in the process of breaking down and transforming dead organic material into forms that can be reused by other organisms and thus the microbial enzyme systems involved are viewed as key ‘engines’ that drive the Earth's biogeochemical cycles.
Soil microbes essentially transfer carbon between environmental compartments to fulfil their fundamental goal: survival through reproduction.
Thus, microbes utilize different organic and inorganic forms of carbon as carbon and energy sources.

Compare and contrast a provirus and viral DNA.
A provirus is viral DNA incorporated into the host cell’s DNA.
A provirus is newly replicated viral DNA after injection.
A provirus is the host cell’s DNA that has been destroyed.
A provirus is bacterial DNA incorporated into the viral DNA.
The main difference between 'provirus' and 'viral DNA' is that provirus is viral DNA incorporated into the host cell’s DNA (Option 1)
A provirus can be defined as the genetic material (DNA) of a particular virus which is integrated into the genome of an individual.Since a provirus is already integrated into the host's genome, this sequence can be transmitted from one generation to the next by cell division (either mitosis and meiosis depending on the cell type).For example, the human immunodeficiency virus (HIV) is a retrovirus whose genome is integrated into the host genome (e.g., into host CD4 cells), thereby making it a provirus.Learn more in:
