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.Scientists discovered bacteria for the first time in the 1920s true or false
Answers
The correct answer is False
Explanation:
In biology, bacteria are unicellular and prokaryotic organisms as they do not contain a nucleus. Bacteria are mainly characterized by their simple structure, the capability to survive in almost any environment and small size.
In terms of discovery, bacteria were unknown for many centuries; however, this changed in the 17th century as the Dutch scientist Van Leeuwenhoek designed a microscope and was able to observe a bacteria for the first time in 1676. This also led to subsequent studies and in this way nowadays there is a lot of information about this type of microorganism. According to this, it is false scientists discovered bacteria for the first time in the 1920s as bacteria were discovered in 1676.
Why is there disagreement on drilling oil reserves in the Arctic National Wildlife Refuge (ANWR)? A) The disagreement stems from a need to remove more nonrewable resources from an area set aside for the ecological health of wildlife. B) The disagreement is about how much oil is actually in ANWR. 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.
Answers
Debate has been ongoing since 1977 as to whether to drill oil in the ANWR or not. The oil merchants of the United States and some of its government officials want the refuge to be drilled for oil while many powerful environmental organisations, which stand for the people of the United States object to this idea. The refuge is one of the few true wilderness which still exist in America and it is home to many species of animal. Drilling oil in this location will throw the ecosystem into a great imbalance.

The presence of chondrocytes indicates that a tissue is ________.
Answers
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.

How many moles of O2 are required for the complete reaction of 88.9 g of C2H4 to form CO2 and H2O?
Answers
To answer this question, you need to know the reaction formula for the problem. The formula should be:
C2H4 + 3O2 --> 2CO2 + 2H2O
In the formula, every 1 C2H4 will be reacted with 3 O2. Then the amount of oxygen needed would be: 3/1 * 3.175 mol= 9.525 mol
list the organelles found in plant cells, in amoeba, and common to both.
Answers
tonoplast, mitrotubule , nuclear pores
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.

Why was the evolution of vascular tissue important to plants conquering the land?
Answers
Vascular tissues are required for the proper translocation of food, water and other minerals in a plant body which is essential for the survival of a plant on 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.
