Answer: The correct answer is rRNA and protein.

Explanation:

Ribosome is a cell organelle present in the cytoplasm of all living cells. It is a site of protein synthesis in all type of cells. It is made up of two sub-units namely, small sub-unit and large sub-unit.

Both the sub-units are formed by rRNA (ribosomal RNA) and associated proteins. rRNA is ribozyme, that is, it is a ribonucleic acid with catalytic ability. The protein component helps in providing the structure to the ribosome.

Answer:

RNA and proteins.

Explanation:

Ribosomes are membrane-free granules made up of protein-associated RNA molecules, present in all cell types and visible only through the electron microscope. They are formed by two subunits of different sizes and densities, being called major and minor.

Ribosomes are responsible for the synthesis of proteins by joining their amino acids. This synthesis is controlled by mRNA (messenger RNA) formed in gene transcription under DNA command. MRNA, associated with a group of ribosomes called polyribosomes, guides the sequence of amino acids that will form proteins. These amino acids are brought by the tRNA (carrier RNA) and are nested according to the sequence determined by the mRNA. As polyribosomes traverse the mRNA strand, proteins are synthesized.

The presence of a meal in the stomach triggers an increase in the colonic motility and an increase in the frequency of mass move

34kurt

Answer: Gastrocholic reflex

Explanation:

The gastrocholic reflex or gastrocolic response is one of the physiological reflexes in the stomach which controls the movements like peristalsis and motility in the gastrointestinal tract.

This reflex is generated by the the food particles that enters the stomach. The bolus of the food in the stomach helps in the mass movement of the other food particles in the colon.

This reflex is known as gastrocholic reflex.

Birds, insects, and many reptiles excrete nitrogenous waste in the form of uric acid, which _____. see concept 44.2 (page 980)

Nadusha1986 [10]

Birds, insects, and many reptiles excrete nitrogenous waste in the form of uric acid, which saves water.
Nitrogenous waste in the body tend to form toxic ammonia, which must be excreted. Mammals such as human excrete urea, while birds, reptiles, and some terrestrial invertebrates produce uric acid as waste in the form of a white paste or power. The production of uric acid involves a complex metabolic pathway that is energetically costly in comparison to processing of other nitrogenous wastes such as urea or ammonia, it has the advantages of reducing water loss and, hence, reducing the need for water.

Explanation:

All observations and information that scientists perceive and record are called data.
A dependent variable, also known as response variable, defines the treatment/variable that changes in response to the independent variable.
According to the second postulate of the Cell Theory, the cell is the basic structural and functional unit of life.
Cells that perform similar functions are grouped together to form tissues.
An experiment is a controlled setting/test that investigates (proves or disproves) a scientist's hypotheses.
One of the major properties of life is to harvest and convert energy to drive basic cellular processes.
Independent or test variable does not depend on any other factors. It is itself changed to determine its effect on the response variable.The amount of coke is the independent variable.
Homeostasis is defined as an organism's ability to regulate its internal environment in response to fluctuations in the external environment.
A community is a group of populations (different species) inhabiting one place at one time.
In the scientific method, a good theory generates further hypotheses that can be tested.
Multicellular organisms are composed of more than one cells.
Biology is the scientific study of life. <em>Bio</em> means life and <em>logos</em> means study, thought or reasoning.
An ecosystem is an ecological structure in which both biotic and abiotic factors interact with each other.
According to the second postulate of the Cell Theory, the cell is the basic structural and functional unit of life.
Eukaryotes constitute one entire domain of the tree of life. They are distributed in 4 major kingdoms of life.
A dependent variable, also known as response variable, defines the treatment/variable that changes in response to the independent variable.
Homeostasis is defined as an organism's ability to respond and regulate its internal environment in response to fluctuations in the external environment.
Homeostasis is defined as an organism's ability to respond and regulate its internal environment in response to fluctuations in the external environment.
The experimental and control groups differ in the independent variable as only the experimental group receives the variable or treatment.
Quantitative data is quantifiable, numerical data in which the effects of the independent variable on the response variable can be compared through mathematical and statistical tools.
A good theory is universal,broad in scope and substantiated by a large body of evidence.
A good theory is universal,broad in scope and substantiated by a large body of evidence.
A jungle is a group of a single species of dense vegetation.
An organism is an individual living being composed of cells, tissues, organs and organ systems.
Fungi, being saprophytic in nature are the principal decomposers on Earth.
Independent or test variable does not depend on any other factors. It is itself changed to determine its effect on the response variable.
A population is a single species of organisms inhabiting a single area at a time.
Organisms of the domain Archaea are known to be extremophiles i.e. organisms that can survive and thrive in harsh environmental conditions.
A hypothesis is a potential explanation for observable phenomena.
The three domains of life: Eukarya (Eukaryotes), Archaea and Bacteria (Prokaryotes).
The three domains of life: Eukarya (Eukaryotes), Archaea and Bacteria (Prokaryotes).
A cell is made up of different organelles performing diverse functions for the cell.
The properties of life include: order, sensitivity or response to the environment, reproduction, growth and development, regulation, homeostasis, and energy processing.
Each level of the hierarchy of life entails the addition of new properties, complexity and more complex functions.
One of the major properties of life is to harvest and convert energy to drive basic cellular processes.
A well tested and substantiated hypothesis leads to the development of a theory that can further be subjected to experimentation.
An ecosystem is an ecological structure in which both biotic and abiotic factors interact with each other.
Independent or test variable does not depend on any other factors. It is itself changed to determine its effect on the response variable.
The three domains of life: Eukarya (Eukaryotes), Archaea and Bacteria (Prokaryotes).
