The given question is incomplete question as it lack essential part of question which is :
Ex: Write a hypothesis about the worms and lima bean plants. Be sure to answer the lab question.
Answer:
The correct answer would be : If plants grow in soil with worms, then growth of the lima bean plant will be greater due to worms helps in decomposing organic matter.
Explanation:
In this hypothesis the one species benefits other species in the same ecosystem they both exist. According to the hypothesis presence of the worms helps in the growth of the lima bean plants.
Dependent variable is a variable that depends on change in independent variable. Here the change in the presence of worms affects the growth of the bean plants so, the dependent variable is bean plant and the independent variable is presence of the worms.
Thus, the correct answer is : If plants grow in soil containing worms, then plant growth will be greater, because worms help decompose organic matter
Answer: The correct answer is-
muscle, nervous, connective, and epithelial.
Tissue can be described as a group of specialized cells that are clustered together to perform particular function.
There are primarily four main types of tissue, which are present in the human body. These tissues are-
Muscle tissue ( assist in locomotion and provides structural support to body).
epithelial tissue ( covers surface of body surface and forms internal lining in most of the organs),
connective tissue ( such as bones, cartilage, blood) that is abundantly present in the body.
nervous tissue ( helps in the transmission of electrical signals through out body).
---C---- if brown snails are mostly eaten that most likely means they are more common. If less than snails are eaten then stripedsnails would eventually over populate brown snails and then brown snails would overpopulate striped snails ..... so elminate b and d and snails probably won't go extinct..... so I would have to go with c
Answer: The statement is TRUE.
Explanation:
Gram negative bacteria is a type of bacteria that possesses, from the interior to the exterior, a cytoplasmic membrane, a thin peptidoglycan layer, and an outer membrane containing lipopolysaccharide. The lipid portion of the lipopolysaccharide complex of the outer layer acts as an ENDOTOXIN.
The endotoxin of the gram negative bacteria can be detected in research or biomedical laboratories through a technique called LIMULUS AMEBOCYTE LYSATE test.
The test procedure follows a principle that the endotoxin of these gram negative bacteria are capable of forming gel clots (coagulation) of blood cell (amoebocytes) lysates of the Limulus polyphemus crab.
Therefore, If LAL (limulus amebocyte lysate) turns into a gel when exposed to a sample, it
means the sample is contaminated with endotoxins of gram-negative bacteria.
