The correct answer is rhizome.
Rhizome is a modified horizontal underground stem. Rhizome may or may not be fleshy. It becomes fleshly when it stores food as in ginger. It looks like root but it is not root because there is presence of nodes, internodes, scale like leaves on it and it is frequently develops branches in different direction. Through rhizome many plants propagates vegetatively.
Answer:
A rhizome is a horizontal stem that can divide and grow in several directions at once.
Before forming a hypothesis, an individual firstly makes an observation and formulates a question. Conducting some research follows, which aids in the formation of a hypothesis. A hypothesis, which is an educated guess, predicts the outcome of a situation.
The steps leading up to the formation of a hypothesis typically involve first making an observation about the natural world. This could include noting a trend, pattern or single event. From this observation, questions might arise that the observer seeks to answer. Following observation and question formulation, the next step is often to conduct some research about the topic which can inform the creation of a hypothesis. A hypothesis is a testable statement that predicts the outcome of a situation given certain conditions, often presented in an "If... then..." format. It serves as an educated guess to explain the initial observation.

B) Leukopenia decreases the body's ability to fight infection.
C) Leukopenia has no effect on the body's ability to fight infection.
D) Leukopenia increases the body's ability to fight infection at certain times and decreases it at other times.
Answer: B) Leukopenia decreases the body's ability to fight infection.
The condition Leukopenia results due to decrease in the count of the white blood cells. It results typically due to the decrease in the number of neutrophil. White blood cells are important for maintaining the immunity within a human body. These cells protect the body against the foreign invaders like bacteria, viruses hence, prevents infection. As, the number of white blood cells decreases the body's ability to provide protection against foreign invaders decreases and hence, infection occurs.
Therefore, B) Leukopenia decreases the body's ability to fight infection is correct.
Leukopenia is a condition characterized by a decrease in white blood cells. Leukopenia decreases the body's ability to fight infection and the correct option is option B.
White blood cells, also known as leukocytes, play a crucial role in the body's immune response. They help identify and destroy foreign substances such as bacteria, viruses, and other pathogens. When a person has leukopenia, the reduced number of white blood cells means there are fewer immune cells available to defend against infections.
With a lower count of white blood cells, the body's ability to mount an effective immune response is compromised. It becomes more challenging to identify and eliminate invading pathogens, making the individual more susceptible to infections. Leukopenia can weaken the immune system, making it harder for the body to control and eradicate infections properly.
Thus, the ideal selection is option B.

So in an enviroment the ones with a better adaptations will survive and pass on thier traits to the next generation. If a group of rabits have smaller feet and hop faster than other jack rabbits, then they will survive when chased by predators, and pass on thier traits, while others would get eaten. Over time the generations would have more rabbits with small feet and faster speeds until all rabbits have that trait.
a double helix best describes the structure of the sides of the DNA molecule. The correct option is A.
Thus, Deoxyribonucleic acid, or DNA, has a double helix-like structure. It is made up of two lengthy nucleotide strands that are spirally coiled around one another.
The complementary nitrogenous bases adenine (A) and thymine (T) and cytosine (C) and guanine (G) form hydrogen bonds that hold the two strands together.
This double helix structure is frequently compared to a spiral staircase or a twisted ladder.
Thus, a double helix best describes the structure of the sides of the DNA molecule. The correct option is A.
