How does a lion get its source of nitrogen to form its DNA or proteins?
Answer: The protein in their diets
Explanation:
The lion gets its source of nitrogen to form protein in its diet.
What is protein?Proteins are macronutrients that are present in foods. There are two types of proteins. Essential and nonessential. Non-essential proteins are synthesized in the body and essential proteins are needed to eat by taking food.
A lion is an animal, and animals synthesize some proteins in their body, and some proteins are to be taken from the food. Protein is necessary for the growth of the body. It gives strength to the body.
The protein synthesis is done in the cell of the animals. But the nitrogen, that the animals get is from the diet they eat which is meat and plants. It depended upon its diet. Some animals are carnivorous and some are herbivorous.
Therefore, the lions get their protein from their diet.

Why is it logical for the level of FSH to fall greatly following ovulation?
Answer:
During each menstrual cycle, there is a rise in follicle stimulating hormone (fsh) in the first half of the cycle that stimulates follicular growth in the ovary. After ovulation the ruptured follicle forms a corpus luteum that produces high levels of progesterone. This inhibits the release of fsh!

Metal are malleable and ductile. Explain on the basis of the electron sea level?
Metallic Bonding is restricted to metals only. In the metallic bonding, There is a electrostatic force of atrraction between the metal ions (which are positive)
and the electrons(which are negative).
The metal ions are arranged in a lattice pattern which is the regular repetitive structure.
_____________________________________Electron Sea Level:Every metal atom donate one or two valence electrons, so due to the BULK presence of the electrons, It results in a formation of sea of electrons. So the valence electrons don't just stay on their own atom, they roam around the whole metal. They are just like a sea of electrons. This is why it is called the electron sea model. basically metal ions are present as a iceberg or island in the freely floating sea of electrons.
_____________________________________How is Sea of electron related to the malleable and ductile property?The sea of electron works as a electron GLUE, That means the metal ions are strongly ATTRACTED to the electron, so When apply pressure on the metals they DONT BREAK that means they are not brittle but malleable and ductile. This is because of the moving electrons and because the cations slide easily past each other, The ability of the atoms to roll over each other into new positions without breaking the metallic bond is because of the electron glue.
_____________________________________IMPORTANT STATEMENTSBrittle; Hard but breakable due to absence of sea of electron.
Malleable and Ductile; Transformed into sheets and thin wires so they are somewhat ELASTIC.

Why do you think surface waves are the slowest moving waves?
Answer:
S waves are more dangerous than P waves because they have greater amplitude and produce vertical and horizontal motion of the ground surface. The slowest waves, surface waves, arrive last. They travel only along the surface of the Earth.
Explanation:
Answer:
They move a little more slowly than P waves, and can only pass through solids. As S waves move, they displace rock particles outward, pushing them perpendicular to the path of the waves. ... Surface waves are the slowest moving of all waves, which means they arrive the last
Explanation:
How does the information from the stimuli get communicated to the brain?
Answer:
Explanation:
Sensory receptor interact with stimuli, such as light sound temperature and pain which is transformed into the code that is carried to the brain by the chain of neurons. Once the signal reaches the end of an axon, which is at the end of neuron, a neurotransmitter is released and the process repeats.
The information is sent in the form of nerve impulses and reaches the spinal cord through the sensory neurons of the PNS.

The study of genes and inheritance is called genetics. In a gene pair, one allele is dominant and the other is recessive.
The correct answer is the variation in gene combination.
What is polygenic inheritance?A character that is controlled by more than one pair of alleles is called polygenic inheritance. The best example is skin pigmentation which is controlled by 6 alleles or 3 gene pairs.According to the question, pigmentation is different due to the combination of the different genes. These genes produced melatonin which decides the skin tone, The dominant genes code for a darker tone, and the recessive gene code for a lighter tone.
Hence, the correct answer is mentioned above.

What are the products of krebs cycle?
Answer:
What are the Krebs Cycle products? Electron Carriers (NADH and FADH2), ATP, and Carbon Dioxide.
Explanation:
For one cycle, two molecules of carbon, three molecules of NADH, one molecule of FADH2 and one molecule of ATP or GTP are produced. Each glucose molecule produces two molecules of acetyl CoA, enough for two cycles. These products can be multiplied by two to produce the per-glucose yield. Though only one ATP (or GTP) is produced directly per cycle, the products NADH and FADH2, can produce ATP (or GTP) in a further process of cellular respiration called oxidative phosphorylation. The main function of the Krebs cycle is to produce energy, stored and transported as ATP or GTP. The cycle is also central to other biosynthetic reactions where the intermediates produced are required to make other molecules, such as amino acids, nucleotide bases and cholesterol. The Krebs cycle is found in all cells that use oxygen. Combined with the process of oxidative phosphorylation, the Krebs cycle produces the majority of energy used by aerobic cells with the percentage energy provided for humans being greater than 95%.
What is the process by which cells release energy in the absence of
oxygen? -
possible answers :
aerobic
anaerobic
calorie
cellular respiration
fermentation
glycolysis
Krebs cycle
matrix
NAD+
Answer:
This process is called aerobic respiration because it requires air (oxygen). In the absence of oxygen, the cell uses a process called anaerobic fermentation. or simply fermentation. ... Because aerobic respiration breaks the sugar all the way down, it releases much more energy than fermentation.
Why is it more common for birds to have nests with a few eggs rather than just one or a lot?
Explanation:
The large size of a egg makes it difficult for the female to retain more than a single one egg at a time - carrying eggs would make flying harder and require more energy. (Bird eggs vary in size from the tiny 0.2 gramme eggs of hummingbirds to the enormous 9 kilogram eggs of the extinct elephant bird.)
Just as an aircraft cannot fly if it is overweight, all female birds must dispense with the fertile egg as soon as it is formed. And because the egg is such a protein-rich high-nuitrition prize to all sorts of predators, birds must find a secure place to hatch their eggs. Although birds' eggs appear to be fragile, they are in fact extremely robust. The oval shape applies the same rules of engineering as an arched bridge; the convex surface can withstand considerable pressure without breaking. This is essential if the egg is not to crack under the weight of the sitting bird. It takes 26 pounds of pressure to break a swan's egg and 120 pounds to smash the egg of an ostrich.
Female birds have one working ovary, unlike mammals, which have two. Ovaries are the organs where eggs are produced. A bird's ovary looks like a tiny bunch of different-sized grapes.
