Answer:
It takes 27 days, 7 hours, and 43 minutes for our Moon to complete one full orbit around Earth. This is called the sidereal month, and is measured by our Moon's position relative to distant “fixed” stars. However, it takes our Moon about 29.5 days to complete one cycle of phases (from new Moon to new Moon).

Which two organelles work together to create a functional protein.
Answer:
J
Explanation:
The two organelles that work together to create a functional protein are the ribosome and the endoplasmic reticulum (ER).
What if the function of ER and ribosome?The ribosome is responsible for synthesizing the protein, while the endoplasmic reticulum provides the environment in which the protein can fold into its functional 3-dimensional structure.
In the cytoplasm, the ribosome reads the genetic information in messenger RNA (mRNA) and uses it to assemble a chain of amino acids, forming a protein. The ribosome then transfers the newly-formed protein to the endoplasmic reticulum.
The endoplasmic reticulum is a network of membranes that runs throughout the cytoplasm. It is involved in many cellular processes, including the folding and modification of newly-synthesized proteins. In the ER, the protein undergoes a series of post-translational modifications, such as the addition of carbohydrates, lipids, or phosphate groups. These modifications help the protein fold into its functional 3-dimensional structure and determine its final function in the cell.

Why do living things share fundamental characteristics
Answer:
All living organisms share several key characteristics or functions: order, sensitivity or response to the environment, reproduction, growth and development, regulation, homeostasis, and energy processing. When viewed together, these characteristics serve to define life.
Life processes are important to carry out daily life activities. They help to produce energy and maintain homeostasis in the body. The life processes help a body survive with the changes in the environment.
There are several fundamental characteristics or capacities that all living things share, including order, environmental sensitivity or responsiveness, reproduction, growth and development, regulation, homeostasis, and energy processing.
What fundamental characteristics share by living things?All living things share certain basic characteristics or functions, such as order, sensitivity to their environment, growth and development, reproduction, regulation, homeostasis, and the ability to process energy.
These characteristics work to define what it means to live. These characteristics collectively contribute to the definition of life. All of these characteristics will be found in living things.
All living things share the capacities to procreate, grow and develop, use energy, maintain homeostasis, respond to their environment, and be adaptable.
Therefore, all living things share fundamental characteristics.

Which cell type undergoes terminal differentiation?
A-epithelial cells
B-stem cells
C-heart cells
D-hair cells
Stem cells are the cell type that undergoes terminal differentiation.
STEM CELLS:
Stem cells are cells in animals that are capable of differentiating into any cell type. Differentiation of a cell implies that the cell becomes more specific in its function. Stem cells undergo mitotic division to produce one daughter cell that is a stem cell and another daughter cell that has differentiated. Stem cells undergo terminal differentiation into specific cell types such as epithelial cells, muscle cells, heart cells, hair cells, blood cells etc. Therefore, stem cells are the cell type that undergoes terminal differentiation.Learn more at: https://brainly.com/question/11161299?referrer=searchResults

the all-or-none response of a neuron is similar to:
Answer:
The all-or-none law is a principle that states that the strength of a response of a nerve cell or muscle fiber is not dependent upon the strength of the stimulus. If a stimulus is above a certain threshold, a nerve or muscle fiber will fire.
The all-or-none response of a neuron is similar to a gun that either fires or doesn't. The correct option is B.
What is an all-or-none response?According to the all-or-none principle, signal transmission between neurons is solely dependent on the initial threshold being met rather than the stimulus's intensity.
In other words, neurons either fully or totally avoid transmitting an impulse via the synapse to the subsequent neuron.
According to the all-or-none law, the strength of a nerve cell's or a muscle fiber's response is not influenced by the stimulus's intensity.
A nerve or muscle fiber will activate if a stimulus is present above a predetermined threshold.
Therefore, the correct option is B. a gun that either fires or doesn't.

The chart below lists different plant species with a description of adaptations. Plant Species Adaptation Turkey Feet Grass This plant has very deep roots to prevent soil loss in windy areas, and to help anchor the plant. Pinkflower Hedgehog Cactus Contains spines for protection, and a waxy coating on the sunny side of the plant to help prevent water loss. Devil’s Walking Stick Secrete chemicals as a defense mechanism, and have broad leaves to catch sunlight in shady areas. Hairy Manzanita Pale pink flowers attract humming birds for pollination. Which plant species above is best adapted for a grassland biome? a Turkey feet grass b Pinkflower hedgehog cactus c Devil's walking stick d Hairy Manzanita
Answer:
A) Turkey feet grass
Explanation:
Grassland biome is one of the biomes that makes up the Earth's biosphere. Due to the characteristics of this biome (grassland), it favours the abundance of grass species over trees and shrubby plants. These characteristics include a low annual rainfall, soil's susceptibility to wind erosion etc.
Based on these characteristics, an organism that will thrive in this biome must be structurally adapted to it. This is the case of the Turkey feet grass mentioned in the question. The Turkey feet grass possess very deep roots to prevent soil loss in windy areas, and to help anchor the plant. This is as a result of soil loss common to the soil of grassland biomes.
