Answer:
Explanation:
Carbohydrates consist of single-sugar units called monosaccharides, double-monosaccharide units known as disaccharides and multiple-monosaccharide molecules that make up starches. The predominant purpose of the carbohydrates you eat is to provide fuel to your cells. Disaccharides and starches undergo digestion to reduce them to their individual sugars, and, once absorbed, they travel to the cells and tissues throughout your body to power your physical activities. Proteins consist of 20 different amino acids, mixed and matched to create a vast array of larger molecules that support every process in your body. Digestion of protein results in a pool of single amino acids that your cells incorporate into new proteins as the need arises in your body. These molecules make up muscles and organs, transmit signals between cells, constitute immune molecules, help create the new proteins your tissues require and can serve as a fuel source in a pinch. Your cells contain two types of nucleic acids, ribonucleic acid and deoxyribonucleic acid, or RNA and DNA, respectively. They differ from the other macronutrients in that they are not a source of calories in your diet, and their role is strictly to direct the synthesis of new protein molecules. Made up of units called nucleotides, the nucleic acid DNA contains the genetic blueprint that influences your personal characteristics, while the nucleic acid RNA pulls together amino acids to form new proteins as your cells need them.
Nitrogen is found in nucleic acids in the form of nitrogenous bases, which are components of nucleotides. Carbon, hydrogen, and oxygen make up carbohydrates and lipids.
What are macromolecules?Macromolecules are essentially polymers, which are long chains of molecular subunits known as monomers.
Long polymers are found in carbohydrates, proteins, and nucleic acids. They are classified as macromolecules due to their polymeric nature and large size.
Carbohydrates, nucleic acids, and proteins are frequently found in nature as long polymers.
They are classified as macromolecules due to their long chain building nature and massive size. Macromolecules are large (macro-) molecules formed by the joining of smaller subunits.
Carbohydrates and lipids are made up of only three elements: carbon, hydrogen, and oxygen. Proteins are comprised entirely of the elements carbon, hydrogen, oxygen, as well as nitrogen.
Carbon, hydrogen, oxygen, nitrogen, and phosphorus are all components of nucleic acids like DNA and RNA.
Thus, these are the basic differences between the carbohydrates, proteins and nucleic acids.

The grass population will decrease rapidly, and the snake population will increase rapidly. d. The grass, rabbit, snake, and hawk populations will all decrease rapidly.
Answer:D
Explanation
took test
Trapping has severely reduced the population of rabbits in an ecosystem, so the most likely effect this will have on other organisms is that the snake population will decrease rapidly and the grass population will increase rapidly, as in Option A.
What is a predator-prey relationship?Rabbits are prey species, which means they are hunted by predators such as snakes and hawks, and rabbits are also herbivores, which means they eat plants such as grass, so if the rabbit population is significantly reduced due to trapping, it could have several effects on other organisms in the ecosystem such as the predator species, the snake, will decline, but the grass will increase as the rabbit population decreases.
Hence, the most likely effect this will have on other organisms is that the snake population will decrease rapidly and the grass population will increase rapidly, which is option A.

When a stem cell differentiates and changes in size and shape, specific genes are being EXPRESSED.
Gene expression involves the flow of genetic information from genes (DNA) to RNA and proteins.
Differentiation involves first the transcription of genes to messenger RNAs (mRNAs) and second the translation of these mRNAs to proteins.
During gene transcription, a fragment of DNA called 'gene' is used as a template to create an mRNA in the cell nucleus.
Subsequently, this mRNA travels to the cytoplasm where it is then used as template to create a protein by the process of translation.
In conclusion, when a stem cell differentiates and changes in size and shape, specific genes are being EXPRESSED.

Which immune cell is part of acquired immunity?
A. Macrophage
B. Eosinophil
C. Plasma cell
D. Neutrophil
Answer:
C. Plasma cell.
Explanation:
Acquired immunity is developed in the body following a previously encountered infection. The innate immunity by definition, always present in the body and is used to attack all general forms of infection.
The granulocyte cells are considered part of innate immunity and help mediate the immune response against foreign pathogens. These cells include basophils, neutrophils, eosinophils, mast cells, and macrophages (which are differentiated from monocytes).
The adaptive immune response involves the production of antibodies against specific target antigens. Plasma cells are an integral part of the adaptive response and secrete large volumes of antibodies in response to a secondary infection by a previously encountered pathogen. T-cells and B-cells are also part of the adaptive response.

For this activity, you will be researching the Burmese python's impact on the Everglades National Park ecosystem in Southern Florida. These articles are an excellent place to start your research: Python and Impact of Invasive Alien Species.
After completing your research, you will analyze data on the current methods being implemented to control the python population and create a plan to solve the issue. You will then write a letter to the park ranger detailing your plan to control the python population in this ecosystem. Take a look at this student sample letter to see how your letter should be setup.
Burmese pythons are having a significant impact on the ecosystem and biodiversity in the Everglades and surrounding areas. As an invasive species, the python has no natural predator in Florida, making it an apex predator in the area. Therefore, the population of these snakes is not being naturally controlled.
Our innovative solution involves baiting the cages with pheromones, so that the snakes believe they are tracking the scent of the opposite sex. Since Burmese Pythons are usually solitary creatures, these traps will be especially useful during breeding season, to catch male pythons.

3. From problem 2, suppose another boy, Boy C pulls the heavy cabinet with 5 N
of force in the same direction with Boy A,
a. What will be the net force on the cabinet?
b. Will the cabinet move?
c. In what direction will the cabinet move?
Answer and Explanation:
As you can see the boys are pulling in the same direction. This means that we have an example of an unbalanced force, also called the resulting force, since the forces are not canceling out. This whole situation will have a result which is to create an unbalanced net force to move the object or keep it in repayment and that is what we will discover.
First, let's find out what force the two boys exerted. This is very simple, we only need to add the force exerted by the two. 5N + 5N = 10N
The cabinet will be able to move if the force exerted by the two boys (10N) manages to overcome the resistance and the force exerted by the cabinet itself. If they manage to overcome the resistance of the cabinet, the cabinet will move towards the force applied by the boys.
