Answer:
Energy affects competition in the tropical rainforest due to the dense population of trees found in this region.
Trees are producers and they compete mainly for water, sunlight and nutrients. Sunlight provides the source of solar energy which is instrumental in its photosynthetic process.
The trees form canopies and create competition among the ones who have lower stems and branches while the ones with longer stems continue to grow taller due to the availability of sunlight.
Competition may also affect the organisms living in this region as they compete for food.

There are different kinds of investment. The option that is the most effective public policy in reducing reliance on fossil fuels in the long run is Investing in renewable fuel technologies.
Renewable energy sources is known to give the best way to fulfill the energy needs of the world. While fossil fuels is known to be soon depleted and therefore renewable energy sources are always there.
It is therefore smart to invest in renewable energy as the capability to store renewable power for use when needed makes it better than alternative to fossil fuels.
Investing in renewable energy stocks is known to helps man in spreading one's wings and can bring about a lot of dividend income.

Why do two grams of fat provide a different amount of energy than two grams of carbohydrates? (2-3 sentences)
Answer:
Fats are the slowest source of energy but the most energy-efficient form of food. Each gram of fat supplies the body with about 9 calories, more than twice that supplied by proteins or carbohydrates. Because fats are such an efficient form of energy, the body stores any excess energy as fat.

Vaccines have been subjected to quite a bit of controversy in recent years. Currently, the Centers for Disease Control and Prevention (CDC) recommend that healthy people receive a flu vaccine every year. What are your current perceptions of the flu vaccine? Do you think these recommendations are appropriate? Explain your reasoning.
Answer:
There are many reasons to get an influenza (flu) vaccine each year.
Flu vaccination can keep you from getting sick with flu.
Flu vaccination can reduce the risk of flu-associated hospitalization for children, working age adults, and older adults.
Flu vaccination is an important preventive tool for people with chronic health conditions.
Flu vaccination helps protect women during and after pregnancy.
Flu vaccine can be life-saving in children.
Flu vaccination has been shown in several studies to reduce severity of illness in people who get vaccinated but still get sick.
Getting vaccinated yourself may also protect people around you, including those who are more vulnerable to serious flu illness, like babies and young children, older people, and people with certain chronic health conditions.
Explanation:
Influenza is a potentially serious disease that can lead to hospitalization and sometimes even death. Every flu season is different, and influenza infection can affect people differently, but millions of people get flu every year, hundreds of thousands of people are hospitalized and thousands to tens of thousands of people die from flu-related causes every year. An annual seasonal flu vaccine is the best way to help protect against flu. Vaccination has been shown to have many benefits including reducing the risk of flu illnesses, hospitalizations and even the risk of flu-related death in children.
Flu vaccines helps to reduce the risk of flu-associated illness. And the recommendations made by CDC that healthy people receive a flu vaccine every year is appropriate.
What is flu?"Also called influenza is a viral infection which can be deadly in high risk groups."Flu symptoms include- fever, cough, cold, fatigue, headaches and muscle pain.It causes asthma, pneumonia and chronic diseases.What is flu vaccines?"These are the vaccines that protect against infection by influenza viruses."What is CDC?"It is the National public health agency of the United States."Hence, in order to reduce the disease caused by flu, it is recommended to receive a vaccine.

Which is part of the theory of evolution by natural selection?
A. All animals in a population are able to reproduce.
B. Animals have no variation among themselves.
C. Adaptations cannot be passed along to later generations.
D. Small changes add up over many generations.
Answer:
D. Small changes add up over many generations.
Explanation:
It's not A because not all animals in a population can always reproduce. Some may be infertile.
It's not B because genetic variety is something that occurs naturally. Because of genetic variety, random mutations can occur (these mutations later become adaptations).
It's not C because adaptations can be passed down to later generations. These adaptations can lead to natural selection which eventually leads to evolution.
Which of the following best describes why polar bears are a sub-species of brown bears instead of a completely separate species?
A. Because they both have thick fur and 4 legs, so they are very similar
B. Because they both live on the same continent, so they can’t be two separate species
C. Because they can still breed in the wild. Once they no longer mate with brown bears, they will be considered a separate species
D. All of the above
what is the resistance of a car light bulb that conducts 0.025 A current when connected to a 12 V car accumulator? Is the current in the bulb steady?
Answer:
R = 480 Ohm
Yes, the current is steady since the power supply is a constant 12V (comming from the battery).
Explanation:
U=I*R
R = U / I
U = 12 V
I = 0.025 A
R = 12 / 0.025
R = 480 Ohm

Humans and gorillas have one different amino acid in their hemoglobin
sequence. What does this say about the evolution of these two species?
A. Gorillas recently evolved from humans.
B. They have no common ancestors.
C. They probably have
recent common ancestor.
O D. They are probably the same species.
SUBMIT
Answer:
they probably have a recent common ancestor
Explanation:
They probably have recent common ancestor. Therefore, option (C) is correct.
What is evolution?Evolution is the process by which species change over time, usually through natural selection. The theory of evolution is supported by a vast body of evidence from many fields, including genetics, paleontology, and comparative anatomy.
Evolution occurs because of changes in the genetic code of organisms, which can be caused by mutations, gene flow, genetic drift, and natural selection. Over time, these changes can accumulate and result in the development of new species from ancestral forms. Evolution is a slow process that occurs over many generations, and it has been responsible for the incredible diversity of life on Earth, from the simplest bacteria to the most complex animals and plants.
The fact that humans and gorillas have one different amino acid in their hemoglobin sequence suggests that they have a recent common ancestor. This is because the hemoglobin protein plays an essential role in carrying oxygen in the blood and is highly conserved across species that share a common ancestor.

Answer:
The answer is option 2.
Explanation:
ATP is the main product of cellular respiration.
Based on the information in the graph, explain what physical process causes the cell to change size.
Answer:
Osmosis
Explanation:
Osmosis is the process in which solvent molecules move from lower to higher concentration through a semipermeable membrane.
When a cell is placed in a hypertonic solution, the cell loses water and moves from higher concentration to lower concentration that is from inside the cell to the water solution and causes shrinking of cell.
Shrinking of cell means decrease in size of the cell along with the passing time and cell loses all its water.
Hence, the correct answer is osmosis.

O 75 percent
O 100 percent
Answer:
50 percent
Explanation:
The answer above is NOT correct.
I took the test on Edge and 50 percent is right!
According to the Punnett square for this cross,50% percentage of offspring is predicted to have blue feathers.
What is Punnett square ?The Punnett square is a table in which all of the possible outcomes for a genetic cross between two individuals with known genotypes are given.
How do you find the Punnett square?Count the total number of boxes in your Punnett Square. This gives you the total number of predicted offspring.
Divide the (number of occurrences of the phenotype) by (the total number of offspring). Multiply the number from step 4 by 100 to get your percent.
Therefore, according to the Punnett square for this cross,50% percentage of offspring is predicted to have blue feathers.
