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.

Answers

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.

Which scenario describes an interaction between two of Earth’s spheres?

Water flows from a stream to a lake.
Gravity moves rocks to another location.
Lions use energy to catch other animals for food.
Bears dig big holes in the ground to protect their young.

Answers

#2: Gravity moves rocks to another location

Answer:

The scenario that describes an interaction between two of Earth's spheres is "bears dig big holes in the ground to protect their young".

Explanation:

The Earth spheres include the biosphere, the hydrosphere, the geosphere, and the atmosphere. In this context, there is an interaction between two spheres: the biosphere and the geosphere, when a bear digs holes in the ground because a living organism that is part of the biosphere is modifying the structure and shape of superficial soil, which is part of the geosphere.

How is it possible to find the
number of heterozygotes in a
sample population, given the
allele frequencies?

Answers

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.

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]​

Answers

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.

Explanation:

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

∙ Chemogeny, or the Chemical Evolution of Life, is the formation of complex organic molecules from simpler inorganic molecules in the oceans by chemical reactions during the Earth's early history.
∙ It is the first step in the evolution of life on this planet that occurred in less than a billion years.
Steps involved in chemogeny are:
Formation of simple inorganic molecules like water, methane, and ammonia in the primitive atmosphere of the earth.
Formation of simple organic molecules from inorganic molecules.
Formation of complex organic molecules like carbohydrates proteins, and fats.

Answers

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.
