As a part of the nitrogen cycle, animals acquire animo acids by doing which of the following?
Answer:
Eating plants. Hope this helps :)
Explanation:
Answer:
By eating plants
Explanation:
The plants uptake the nitrogen by the help of the nitrogen fixing bacteria found in the soil. The nitrogen from the plants is taken by the animals eating the plants. The source of the nitrogen to the animals is the plants containing nitrogen. The plants are also supplied with some of the fertilizers that contains adequate amount of nitrogen in it, which is transferred to the animals when they eat it.
Describe the connection between Homeostasis and Growth and Development and then describe the connection between Homeostasis and Obtaining Energy.
Answer:
Homeostasis is critical to survival.
Growing through creative change is also critical. ... There is a constant dynamic tension between homeostasis and creative change.In biology, energy homeostasis, or the homeostatic control of energy balance, is a biological process that involves the coordinated homeostatic regulation of food intake (energy inflow) and energy expenditure (energy outflow). ... Fifty percent of the energy from glucose metabolism is immediately converted to heat.

which of the following describes a form of active transport
Answer:
the movement of ions or molecules across a cell membrane into a region of higher concentration, assisted by enzymes and requiring energy.
Explanation: Thats the definition of active transport or ATP
It requires energy and moves molecules against a concentration gradient. Option 1 is correct.
Active transport refers to the movement of molecules or ions across a cell membrane against their concentration gradient, requiring the expenditure of energy. Option A correctly describes active transport by highlighting the key characteristics of this process. Active transport mechanisms, such as pumps and carriers, utilize cellular energy, typically in the form of ATP, to transport molecules or ions from an area of lower concentration to an area of higher concentration. This process allows the cell to maintain concentration gradients that are necessary for various cellular functions.
Options B, C, and D describe passive transport processes. Option B describes simple diffusion, where oxygen molecules move from an area of higher concentration to an area of lower concentration without the need for energy input. Option C describes facilitated diffusion, where glucose moves down its concentration gradient with the help of specific transport proteins. Option D also describes passive diffusion, where carbon dioxide molecules move along their concentration gradient without the requirement of energy.
In summary, option A correctly describes a form of active transport by emphasizing the need for energy and the movement against a concentration gradient.

The biological procedure of nitrogen fixation alters nitrogen gas into a form that is advantageous to plants and other microbes. Thus, option C is correct.
What is the regulation of nitrogen fixation in higher plants?In response to ambient oxygen and ammonium levels, transcriptional regulation of nitrogen fixing occurs.
It is advantageous for bacteria to suppress transcription when oxygen levels are high because the nitrogenase components are oxygen labile.
Rhizobium bacteria are involved in nitrogen fixation. These bacteria are found in the roots of leguminous plants, such as pea and bean plants, and by fixing nitrogen in the soil through the use of certain enzymes.
Therefore, In this process, atmospheric nitrogen gas is transformed into ammonia and other nitrogenous molecules that are related.

what are the characteristics of a cancer cell
Answer:
Cancer cells grow and divide at an abnormally rapid rate, are poorly differentiated, and have abnormal membranes, cytoskeletal proteins, and morphology. The abnormality in cells can be progressive with a slow transition from normal cells to benign tumors to malignant tumors.
Essentially, cancer is a disease of mitosis. As such, it occurs when normal cells are transformed into cancerous cells and proliferate uncontrollably. Cancer cells, therefore, are normal cells whose genes (several genes) have been damaged/mutated which in turn cause the cell as a whole to respond differently to signals that control the lifespan of a normal cell.
Because they do not respond to signals/instructions that control the development and death of normal cells, cancer cells continue to grow and proliferate and even invade other parts of the body. In the process, some of the cancer cells end up forming tumors not only at the first region to be affected (lungs etc) but also result in secondary malignant growths away from the primary site known as metastasis....
Some of the main characteristics of cancer cells that differentiate them from other normal cells include:
-Abnormally shaped and significantly vary in size
-Incapable of self-repair
-Do not go through normal apoptosis
-Do not perform normal cell functions (as is the case with specialized cells)

18. If the inside & outside of a cell are both isotonic, does water still
move across the cell membrane? Explain.
Answer: Yes
Explanation:
Isotonic means equally inside and outside the cell water can move out and in within not net movement.
In an isotonic environment, the relative concentrations of solute and water are equal on both sides of the membrane. There is no net water movement, so there is no change in the size of the cell

Electric current is the flow of electrons from the high potential energy position to the lower potential energy position. Current flow is the direction a positive current would be traveling, or the opposite direction that electrons actually flow. A closed loop containing current flow is called an electric circuit.
Hydrogen bonds in water molecules are formed between:
A. ions in solution between the molecules.
B. nuclei of adjacent molecules.
C. hydrogen and oxygen atoms of adjacent molecules.
D two hydrogen atoms of the same molecule.
E. two oxygen atoms of the same molecule.
Hydrogen bonds in water molecules are formed between hydrogen and oxygen atoms of adjacent molecules. Hence, option c is the correct answer for the statement.
What are different types of bonds?
There are various types of bonds, such as covalent bonds, hydrogen bonds, ionic bonds, etc. In covalent bonds, valence electrons are shared; hence, this bond is called a covalent bond. It is one of the strongest bonds. In ionic bonds, two ions, such as an anion and a cation, form a bond. An example is sodium chloride.
The hydrogen bond is not a covalent bond; it is made between oxygen and hydrogen, hydrogen and fluoride, etc. Inside water, each molecule is connected to another by hydrogen bonds. Hydrogen (H) and oxygen (O) of one water molecule make hydrogen bonds with hydrogen and oxygen of another water molecule. Inside a single water molecule, covalent bonds are present between hydrogen and oxygen.
Hence, a hydrogen bond is present between the hydrogen and oxygen atoms of adjacent water molecules. Option C is the correct answer .
