PLEASE HELP MEEE I NEED HELP ON THIS QUESTION
Answer:
C. Spore formation
Explanation:
Option C above is the correct answer.
Spore formation is actually a method of asexual reproduction. Fungi actually reproduce asexually via spore formation. Some examples of organisms that reproduce via spore formation are Rhizopus, mushroom, mucor, etc.
The spores are usually stored in sacs which are known as sporangia. When there is a bursting of the sac, spores that are single-celled, thick and thin walled are obtained/formed. The spores are usually resistant to environmental conditions.

He has a fear of public speaking that began in elementary school when he forgot a speech when he was running for student council president. He has been working with the drama teacher at the school to overcome this fear. As graduation approaches, he has started to have difficulty sleeping and has lost his appetite. He has worked hard to earn the opportunity and does think his message of finding his way as a child of immigrants and divorce is important. Still he is beginning to question whether or not he will be able to present the speech in front of such a large crowd. He has spoken to his guidance counselor about his concerns. Explain how each of the following concepts relates to the scenario:
. Phobia .
Sympathetic nervous system
• Intrinsic motivation
• Positive reinforcement
• Extraversion
• Altruism Elaborative rehearsal
Answer:
See explanation below
Explanation:
Phobia: Phobia refers to an extreme and irrational fear of something. It can also be an aversion to something. Philip has a fear of public speaking that began when he forgot a speech in elementary school.
Sympathetic Nervous System: This is one of the response to stressful situations. It is activated by the hypothalamus due to both physical and psychological stress. It directs the body’s rapid involuntary response to dangerous or stressful situations. As graduation approaches, Philip starts to have difficulty sleeping and loss of appetite.
Intrinsic Motivation: This refers to doing something just because it is enjoyable rather than for any external reward. Prior to the graduation, Philip has been working with his drama teacher to help him overcome his fear of public speaking.
Positive Reinforcement: This is a form of reward for performing a task. People can also seek positive reinforcement before they perform an action just so that they perform well. Philip tried to get reinforcement his guidance counselor before his presentation.
Extroversion: This is the inclination to obtain gratification from outside oneself. By questioning whether he would be able to present his speech and impress a large crowd, Philip is trying to obtain gratification from others.
Altruism: This refers to a selfless concern for the happiness and well-being of others. Philip is concerned about how his message would impact others who may be able to learn from his journey of being a child of divorce and immigration.
Elaborating Rehearsal: This is done by helping ones short term memory to store information in ones long term memory. Philip has been preparing to give the valedictorian speech at his high school.

How did the environment affect the populations of peppered moths in the 1800s in
London?
Because of the soot covering everything, the dirtier darker moths will be eaten
less often, allowing them to reproduce and pass their genes on to the next
generation.
Because of the soot covering everything, the lighter colored moths will be eaten
less often, allowing them to reproduce and pass their genes on to the next
generation.
The environment did not affect the peppered moths-- the populations are still
the same.

Genetic variation
Differential survival and reproduction
Which factor will most likely guarantee evolution rather than extinction?(1 point)
larger animal sizes
changes in available food sources
changes in the environment
higher reproduction rates
Answer:
Did you ever get the answers?
Explanation:
Any trait that is to be considered as a competitive advantage, trait must allow the individual to survive better and reproduce more in that environment.
What is evolution?
Evolution is the change in the characteristics of a species over several generations and relies on the process of natural selection. It is decent with modification from preexisting species.
The trait that has the ability of relative fitness which means relative survival and relative reproduction shall be considered as more competitive. Both of these, criteria possess a competitive advantage.
Hooves are more advantageous for horses in the modern era because hooves are better suited for environments with a wider range of vegetation. Hooves help horses run farther and faster on the open prairies, helping them flee from predators and find fresh grass for grazing.
The species which is most likely to adapt and evolve to this change is an insect species with high reproduction rates and a significant mutation rate. This is because insect belongs to r-selected species that have fewer chances of extinction as compared to k-selection species.
The factor which is driven by random events is Genetic variations.
The factor which is most likely guarantee evolution rather than extinction is higher reproduction rates. Because a higher reproduction rate is a characteristic of r-selected species.
Therefore, the option which is correct for each specific question is briefly described.

Which of these body systems has cells that attach to each other to form a leak-proof barrier?
Select one:
Urinary system.

What animals have been dominant in the Cenozoic era
Explanation:
Cave lions, sabre-toothed cats, cave bears, giant deer, woolly rhinoceroses, and woolly mammoths were prevailing species of the Quaternary period. Without the dinosaurs, plant life had an opportunity to flourish during the Cenozoic era.
The Quaternary period was dominated by cave lions, saber-toothed cats, cave bears, giant deer, woolly rhinoceroses, and woolly mammoths. Plant life had a chance to thrive during the Cenozoic era without the dinosaurs.
What are the characteristics of Cenozoic era?From the Cenozoic period nearly 66 million years ago to the present day, life is considered recent.
Plants and animals look the one most like they do today during this time period.
The Cenozoic Era is divided into even smaller periods known as Epochs, so there will be even more guideposts in this Era.
Because of the extinction of many groups of giant mammals during the Cenozoic era, smaller species were able to thrive and diversify because their predators no longer existed.
Thus, big cats, saber-toothed cats, cave bears, giant deer, woolly rhinoceroses, and woolly mammoths monopolized the Quaternary period.
Plant life had a chance to thrive without the dinosaurs during the Cenozoic era.

Which statement correctly describes the flow of energy in photosynthesis?
Answer:
DPhotosynthesis stores energy because energy is released when glucose is formed from carbon dioxide and water. The passage describes a condition that is inherited.
Energy from the Sun flows into plants through photosynthesis, which is also known as “putting together with light,” and eventually into humankind. In the end, humans are powered by the Sun's energy to eat and survive. Thus, option D is correct.
What describes the flow of energy in photosynthesis?Solar energy is converted into chemical energy during photosynthesis, which produces glucose from water and carbon dioxide. The by-product is the emission of oxygen. In the process of breaking down glucose during cellular respiration, oxygen is consumed, which also produces heat and chemical energy.
Photosynthesis is the tremendous energy flow that underlies electricity and is the foundation of all life. Whether we are vegetarians or not, we joyfully devour our food without giving the basic mechanism that provides us with this gift even the least thought.
Therefore, Because energy is released when glucose is created from carbon dioxide and water, photosynthesis saves energy. The paragraph mentions a hereditary ailment.
