Here is a diagram of the digestive system. Where do you think lactase would be most effective? Explain. Be sure to consider the amount of time lactose/food would spend in each area.
Lactase will most likely be found in the small intestine and food spends the largest time there.
The digestive system refers to all the structures that are responsible for the breakdown of food in the body. In each part of the digestive system, enzymes act on the food particles to enable certain conversions.
The enzyme lactase in involved in the digestion of milk and diary products. The enzyme has an optimum pH of about 6 hence it works in an acidic environment. Lactase is found in the small intestine.

What Is Chemogeny ( Chemical Evolution ) ? And Explain The Steps Of Chemogeny [Both Answer In Simple Word/ Simple Answer Which Is Easy To Concept Or Read]
Answer:
Chemogeny may be a theory of chemical evolution that depends on the chemical reactions and formation of drugs on the bases of chemical reactions. This theory says that “Life occurs as a results of evolution of inorganic matter”.
In the 1920's Scientists Oparin and Haldane, developed this hypothesis of the chemical origin of life from the primitive atmosphere of the world having matter like methane, ammonia and water. there have been very low concentrations of oxygen thanks to the presence of high temperatures like 5000-60000C. So, these conditions weren't suitable for the free existence of organic compounds, so reactions started happening .
Under conditions like high sunlight and warmth , inorganic matter gets converted to inorganic compounds. And this might end in the storage of organic compounds, which gets more and more concentrated with the passage of many years.
These compounds interact with one another and end in “life”.
So, chemogeny is that the process of chemical evolution of earth and formation of life from pre-existing matter with the assistance of chemical reactions.

Hopefully I was able to help you with the concept. Good luck!

Based on the diagram,which statement is NOT true?
resistance to exploitation is a battle of wits with your captor
The statement is false because resistance to exploitation is not related to wits.
What is social exploitation?Social exploitation is understood as a social relationship in which some people are abused or used for the benefit of others due to their belonging to that category or status.
An example of social exploitation was slavery in which African blacks were used for different purposes during the colony because they belonged to indigenous communities in Africa.
In the example above, Africans had to submit to their captors by force and had no opportunity to oppose it because resistance to exploitation is not a matter of wits.

How is it possible to find the
number of heterozygotes in a
sample population, given the
allele frequencies?
Explanation:
The frequency of heterozygous individuals. Answer: The frequency of heterozygous individuals is equal to 2pq. In this case, 2pq equals 0.32, which means that the frequency of individuals heterozygous for this gene is equal to 32% (i.e. 2 (0.8)(0.2) = 0.32
To find the number of heterozygotes in a sample population, we need to know the allele frequencies and the total number of individuals in the population. The formula used to calculate the expected number of heterozygotes in a population is based on the Hardy-Weinberg equilibrium principle.
The Hardy-Weinberg equation is given as:
p² + 2pq + q² = 1
Where:
p = frequency of one (dominant) allele
q = frequency of the other allele (recessive) allele
p² = expected frequency of homozygous dominant individuals
2pq = expected frequency of heterozygous individuals
q² = expected frequency of homozygous recessive individuals
To find the number of heterozygotes, we can multiply the expected frequency of heterozygotes (2pq) by the total population size. This will give us an estimate of the number of individuals in the population who are heterozygous for the specific gene of interest.

Which statement accurately compares these flashlights?
O A. The smaller flashlight has less inertia than the larger flashlight, so
it takes less force to change the motion of the smaller flashlight.
O B. The smaller flashlight has more inertia than the larger flashlight,
so it takes more force to change the motion of the smaller
flashlight.
C. The smaller flashlight has less inertia than the larger flashlight, so
it takes more force to change the motion of the smaller flashlight.
O D. The smaller flashlight has more inertia than the larger flashlight,
so it takes less force to change the motion of the smaller
flashlight
The smaller flashlight has less inertia than the larger flashlight, so it takes
less force to change the motion of the smaller flashlight.
Inertia is defined as the property of an object to resist changes in its velocity
when in motion. A larger or bigger body has more mass and inertia as it
requires more force to change the direction of the object.
The smaller flashlight has less inertia than the larger flashlight and hence
requires less force to change its motion due to its smaller size.

what is the difference between plant cell nd animal cell
A plant cell contains a cell wall and chloroplasts, while animals cells do not have these cellular structures.
Chloroplasts are organelles required to produce energy in the form of ATP and thus synthesize simple carbohydrates (e.g., glucose) by the process of photosynthesis.Cell walls are cellular structures that help to support and shape plant cells.Moreover, plant cells generally contain big vacuoles, whereas animal cells generally exhibit small vacuoles.In conclusion, a plant cell contains a cell wall and chloroplasts, while animals cells do not have these cellular structures.

why are different leads are used to measure the ECG
Different leads are used to measure the ECG simply because each lead is recording the electrical activity of the heart from a different direction
Each individual lead's ECG recording is slightly different in shape. This is because when the electrical activity within the heart travels towards a lead you get a positive deflection.
ElectrocardiogramAn electrocardiogram (ECG) is a simple test that can be used to check the heart's rhythm and electrical activity. Sensors attached to the skin are used to detect the electrical signals produced by your heart each time it beats

Explain how natural disasters can change the characteristics of a species for many generations after the disaster. To develop this discussion you will need a minimum of 2 paragraphs.
Answer:
Strong volcanic eruptions and fires can temporarily change regional weather, cooling or heating the air, changing winds, or causing rain. Volcanoes, storms, and floods can kill marine animals directly, or cause long-term problems by depositing debris and affecting the temperature and salinity of water.
Natural disaster especially such as forest fires and hurricanes have the potential to threaten these endangered species to the point of extinction. ... The fires destroy the animals habitats including their homes, nesting grounds, food, and winter shelters.
After a natural disaster, the community will often go through ecological succession and return to the state it was pre-diaster. Healthy ecosystems will bounce back, as natural disasters have occurred on earth for a long time. ... Healthy ecosystems are adapted to withstand natural disasters over the long time.
