Answer: c. water storage.
Savanna is a biome characterized by dry climatic conditions. This biome receives low rainfall as compared to grassland. Therefore, plants are adapted to prevent water loss. They have small sized leaves which prevent water loss by transpiration. Also, they have large tree trunk to store water thus help them to survive in drought conditions.

Answer:
The right answer to this question is option C. Protein
Explanation:
First, what is an organic molecule? It's a molecule that contains Carbon in its composition, and by that, we'll jump into the options on the question. The first one is water, but as you can remember, there's no carbon in water's composition, only oxygen and hydrogen, so this is not a good option. The next one is oxygen, there's no carbon here too, so this is not good either. The last one it sodium chloride, and this one has no carbon either, only sodium and chlorine.
The range of cells receiving the content of copied cells is called the destination area. The correct option is a.
The smallest unit of life is a cell. It is composed of biomolecules. Every living thing is composed of several cell units. Different sorts of creatures contain various types of cells.
The cell divides to form the other cell. This process if called cell division. Cell division occurs during mitosis. All eukaryotic cells go through the process.
There are four stages to the process. The cell divides during the procedure. A daughter cell that is identical to the parent cell is created.
The destination region refers to the set of cells that will get copied cell content. The cell copies the full contest for another cell.
Thus, the correct option is a. destination area.

The correct answer is C.
In replication, an initiator protein unwinds a short length of the DNA double helix. Next, an enzyme known as helicase attaches itself to the unwound helix and begins to break the hydrogen bonds between the base pairs of the two DNA strands, thereby pulling them apart to form a Y shape called a replication fork. The two separated strands act as templates for making the new strands of DNA.
An enzyme DNA polymerase then binds to one of the strands called the leading strand because it is the one oriented in the 3' 5' direction (towards the replication fork) and begins walking along it adding new complementary bases to it. After the new strand is proof read by DNA Polymerase, it is sealed up by DNA ligase, an enzyme specific for this task.
The other strand called the lagging strand because it faces way from the from the replication fork in 5' 3' direction also undergoes the same process with a few minor differences to produce the other new complementary strand.
The Correct answer is C: DNA opens up and each stand is used as template for a new strand
(B) 142.
(C) 141.
(D) 429.
(E) 428.
An mRNA of 429 nucleotides will form a polypeptide chain with 143 amino acids, assuming each codon (set of 3 nucleotides) corresponds to an amino acid and the stop codon is not counted.
For the synthesis of protein in a process known as translation, each triplet set of nucleotides in the mRNA, called a codon, identifies a specific amino acid. Hence, an mRNA of 429 nucleotides would be segmented into a set of 3 to form the different codons for the amino acids. Since 429 divided by 3 is 143, the polypeptide chain resulting from this mRNA would have 143 amino acids.
In this case, the correct answer would be (A) 143. This calculation does not take into account the stop codon that does not correspond to an amino acid, but usually examination questions ignore the effect of the stop codon. To provide the most accurate answer, we would need to know if the mRNA sequence includes the stop codon or not.

Answer:
Frogs have some important internal and external structures that helps them to survive, grow and reproduce. Frog have almost similar internal anatomy to humans.
Frogs have the ability to respire through both lungs and skin. Skin is the external structure that helps them to respire in aquatic ecology.The skins helps to dissolves oxygen from the air and water and releases carbon-dioxide. Skin helps frogs to respire under water but if water do not have enough oxygen, frogs will drown.
An internal structure called liver is present in frog same as human beings. The liver releases chemical called bile that are utilized in digestion of fat and then emptied into the small intestine.
Hence, skin and liver are important for the survival of frog.

Three environmental factors that affect Salmonellagrowth and survival are temperature, moisture, and pH level.
Salmonella is a type of bacteria that can cause food poisoning in humans. It is commonly found in raw or undercooked poultry, eggs, and other food products. The growth and survival of Salmonella are influenced by various environmental factors. Three important factors that affect Salmonella growth and survival are temperature, moisture, and pH level.
Temperature: Salmonella bacteria thrive in temperatures between 40°F (4°C) and 140°F (60°C). This temperature range is known as the danger zone for bacterial growth. At temperatures below 40°F, Salmonella growth slows down, while temperatures above 140°F can kill the bacteria.
Moisture: Salmonella requires a moist environment to grow and survive. High levels of moisture provide favorable conditions for bacterial growth. Dry environments, on the other hand, can inhibit Salmonella growth.
pH Level: Salmonella bacteria prefer a slightly acidic to neutral pH range of 4.0 to 7.0. Extreme pH levels, either highly acidic or highly alkaline, can inhibit the growth of Salmonella.
Understanding these environmental factors is crucial in preventing the growth and spread of Salmonella in food and other environments.
