Which component is more medial: the right lung or the tracheal bifurcation?
Which time period saw the loss of 96% of all marine species and 70% of all terrestrial species?
Answer:
Permian-Triassic mass extinction
Explanation:
The Permian-Triassic extinction event, occurred at about 252 MYA. This period marks the boundary between the Permian and Triassic periods. It is the most severe extinction event that took place on earth, with up to 96% of all marine species and 70% of terrestrial vertebrate species becoming extinct. Due to such a great biodiversity loss, the recovery of life on Earth took a longer time than other extinction events.Which motion of particles across a membrane requires energy

Why was the evolution of vascular tissue important to plants conquering the land?
The evolution of vascular tissues enabled plants to transport water and nutrients efficiently, grow larger, and effectively compete for sunlight in terrestrial environments.
The evolution of vascular tissue was significant for plants' conquest of land, as it allowed them to transport water and minerals from soil to leaves, essential for photosynthesis, and distribute food throughout the plant. This system, composed of xylem and phloem, enabled plants to grow taller and larger, thus outcompeting nonvascular plants that were limited to moist environments and a shorter stature.
The ability to grow taller was beneficial for light capture, and the structural support provided by lignified tissues helped plants thrive in terrestrial ecosystems, resulting in diverse and complex plant life on land.

The presence of chondrocytes indicates that a tissue is ________.
The presence of chondrocytes indicates that a tissue is producing cartilaginous matrix.
What are the functions of chrondocytes?Chondrocytes are the cells responsible for cartilage formation, and they are crucial for the process of endochondral ossification, which is useful for bone development. Also, by mimicking skeletal development chondrocytes play a critical role in fracture repair.
Chondrocytes are mainly responsible for the production of collagen and the extracellular matrix that will lead to the maintenance of cartilaginous tissues within joints. Initial cartilage is composed of the mesenchyme during the fifth week of development.
Chondrocytes arise from cranial neural crest cells (CNCCs) of the neural ectoderm, cephalic mesoderm, sclerotome of the paraxial mesoderm, or somato-pleure of the lateral plate mesoderm.

list the organelles found in plant cells, in amoeba, and common to both.
Answer:
Amoeba are unicellular eukaryotes found in aquatic environments. The organelle that is found in amoeba are nucleus, contractile vacuole and food vacuole and organelle found in plant cells are nucleus, endoplasmic reticulum, Golgi apparatus, vacuole, chloroplast, mitochondria, peroxisomes.
The organelles that are common in amoeba and plant cells are nucleus and vacuole. Both plant and amoeba have a membrane-bound nucleus in which their genetic material is packed.
The role of the vacuole in plant cell and amoeba is that it maintains the proper osmotic pressure in the cell and prevent cell from bursting. It also helps in the collection of waste material and its disposal.
A nurse obtained a client's fasting blood sugar (fbs) at 0700, which was 144 mg/dl (8 mmol/l). the client has an order for regular insulin 8 units every morning. what should the nurse do next
Correction dose = [actual(144mg/dl) - target blood glucose(100mg/dl in a fasting situation)] ÷ correction factor(50) <=>
<=> Correction dose = 1 (0.88) unit
The nurse will need to add 1 unit to the 8 units that are already prescribed.

C) There is no disagreement concerning ANWR supply. The disagreement is about the drilling expense, removal costs, and whether or not the government will subsidize the oil industry.. D) The disagreement is among nuclear waste enthusiasts who want to store their waste, oil companies that want to extract oil, and indigenous people who want to keep their hunting territories. E) There is no disagreement about this area because it is already preserved for wildlife.

The _____ law of thermodynamics states that energy can't be created or destroyed. Two natural sources of energy on Earth are the _____.
A. first, Sun and core of Earth
B. second, Sun and rock
C. second, Sun and biosphere
D. third, core of Earth and hydrosphere
Answer:
Option A, first, Sun and core of Earth
Explanation:
According to first law of thermodynamics,
An energy can never be created nor destroyed, it can only be converted from one form to other and therefore the first law of thermodynamics is known as law of conservation of energy.
There are only few energy sources for planet earth – Solar energy, gravity, rotation of earth and radioactive energy
Solar energy is the prominent source of energy that drives several natural process like winds, hydrologic cycle, biosphere ecological cycle , and also derives the overall climate system . While the earth core causes gravitational force which is very essential for several natural process like rotation, tides, etc.
