Answer: Well, you see, As the cube size increases or the cell gets bigger, then the surface area to volume ratio - SA:V ratio decreases. ... When a cell grows, its volume increases at a greater rate than its surface area, therefore it's SA: V ratio decreases.

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.
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.

Which factors involving the activities of people are a threat to biodiversity? pollution and succession habitat loss and predation poaching and habitat loss succession and poaching
Both poaching and habitat loss are a threat to biodiversity
Habitat loss refers to the destruction of natural ecosystems and consequent reduction in the amount of habitat available for the species living in a given area. Habitat loss is the greatest threat to ecosystems biodiversity and conservation worldwide by deteriorating natural areas and thereby reducing species distribution ranges. Habitat loss is primarily due to the expansion of human populations and human activities (i.e., mining, logging, trawling, industrial production, urbanization, etc.).
Poaching refers to the illegal killing of wild animals for different reasons (e.g., meat, recreation, etc.), in violation of international, federal, state/provincial, or local laws. Poaching can drastically reduce the number of organisms in natural populations, thereby this human activity can reduce genetic diversity and eventually may lead to the extinction of natural populations/species.
In conclusion, both habitat loss and poaching can reduce the number of organisms, reduce biodiversity and eventually cause the extinction of natural populations.

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.
