In the early 1900s, Thomas Hunt Morgan was among the first scientists to contribute to the chromosome theory of heredity. Morgan’s investigations into heredity in fruit flies led him to propose that the event represented in the diagram sometimes occurs.
Which statement about the event presented in the diagram sometimes
occur?
A. The event represents DNA translation in the smooth endoplasmic
reticulum.
B. The event takes place in the bacterial cell.
C. The event produces genetically identical daughter cells.
D. The event provides genetic diversity in eukaryotic cells.
Answers
The statement about the event presented in the diagram sometimes occurs - D. The event provides genetic diversity in eukaryotic cells.
The given event in the diagram is known as crossing over which takes place during the process of meiosis.
Crossing over takes place during the pachytene stage of Prophase I of Meiosis I where the non-sister chromatids of homologous chromosomes exchange genetic materialthis results in the recombination of the genetic material and creates a new genetic combination.Thus, genetic variations occur which can be beneficial to the offspring.Thus, the statement about the event presented in the diagram sometimes occurs - D. The event provides genetic diversity in the eukaryotic cell.

Why do you think there are rarely 5 or 6 links in a food chain? To help, think about how much food it took for all of your energy needs in your life. Imagine if an animal had to eat 10 humans a year to survive.... is this feasible... or there that much energy available?
Answers
Answer:
Most food chains have no more than four or five links. There cannot be too many links in a single food chain because the animals at the end of the chain would not get enough food and energy to stay alive.

in the reference to genetics what does dominance and recessive mean
Answers
Answer: well see if a trait is dominant you are more likely to have said trait if a trait is recessive you are less likely to have said trait
Explanation:
Answer:
dominance is the one that will be seen in a creature, recessive traits will not be seen, but can still be passed on
Explanation:
if both parents pass on the same recessive gene then their child will show that trait, such as two sets of parents, one dark skinned and one light skinned, their children will be dark skinned, but if their children have a child is has a chance of having light skin because they both carry that recessive trait.

What is the original source of hominids?At present, there are chimpanzee, orangutans, humans, and gorillas. The hominids originated on the continent Africa, mainly in the Eastern parts of Africa. The hominids dispersed to other continents from Africa.
The correct order of the most densely populated continents is : Asia, Europe, Africa, North and South America and Australia. Africa has a population of 1.26 million and the population density of this continent is 87,15 people per square mile. Africa is experiencing the world's fastest growing population.
Asia is the most populated continent in the world with a population of 4,5 billion. The population density in Asia is 246,11 per square mile. Approximately 7,6 billion people live on earth on seven continents.

Answer:
Catalyst is a substance that influences the rate of reaction without being consumed in the reaction.
-They increase the rate of reaction by decreasing the activation energy of the reaction.
-As they are not used up in the reaction they are required in a small quantity.
-In biological system, enzymes are referred to as biological catalyst or biocatalyst. They are generally protein in nature and are very specific for their substrate. They also increases the rate of biological reaction by forming enzyme-substrate complex.
-Few examples of catalyst are: potassium permagnet, platinum, enzyme (like hexokinase, hydrolase etc) etc.

Population Growth Form: The graphic pattern obtained when a population growth is plotted against time is called population growth form or model. There are two types namely: Exponential J-shaped and Logistic or S-shaped.
J-shaped or Exponential Growth Form: At any point of time, population size does not reach the equilibrium.
Explanation:
When resources are limited, populations exhibit logistic growth. In logistic growth, population expansion decreases as resources become scarce.

According to the scientific theory of atoms, which of the following statements best describes the location of electrons? A. in the nucleus of the atom B. both in the nucleus and around it C. outside the nucleus and often far from it, in the electron cloud D. outside the nucleus, yet very near it because they are attracted to the proton
Answers
Answer:
D. Outside the nucleus, yet very near it because they are attracted to the proton
Explanation:
Electrons are located outside of the nucleus of the atom, which is made up of neutrons and protons. In physics, the space they take up is informally referred to as the electron cloud. Protons and electrons are attracted to each other, because the positive electric charge of the protons is attracted to the negative charge of the electrons. This is why the electrons are very close to the nucleus.
The best statement that describes the location of electrons is D whichis Outside the nucleus, yet very near it because they are attracted to the proton.
What is electron?An electron is a negatively charged subatomic particle. It can be either free , or bound to the nucleus of an atom.
Electrons in atoms exist in spherical shells of various radii, representing energy levels. The larger the spherical shell, the higher the energy contained in the electron.
Thus, option "D" is correct.

Predict what would happen to the H+ ion concentration if you added sulfuric acid to water. Would the pH increase or decrease
Answers
When a sulfuric acid is dissolved in water, hydrogen ions are produced, increasing the concentration of hydrogen ions in the solution. Result in decrease in pH of solution.
What is PH solution?Indicating the acidity or basicity of a solution, the pH of a solution measures the molar concentration of hydrogen ions in the solution.
The acronym pH stands for “power of hydrogen,” and the pH value in numbers is simply the negative of the molar concentration of H+ ions divided by 10.
A solution's acidity can be determined by looking at its pH, which is a measurement of hydrogen ion concentration.
Pure water slightly separates into ions with roughly equal amounts of hydrogen and hydroxyl (OH) ions.
Nutrient availability, biological processes, microbial activity, and chemical behavior can all be influenced by pH.
Therefore, if you added sulfuric acid to water, pH decrease.
