Scientists discovered bacteria for the first time in the 1920s true or false
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.
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.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.

What will the radicle become as the seed develops into an adult plant?
a. the root
b.the flower
c.the stem
d.the leaf?
Answer: a. the root
Explanation: As the seed develops into an adult plant, the radicle becomes the root. The radicle is defined as the rudimentary shoot of a plant which supports the cotyledons in the seed, and from which the root is developed downward; the root of the embryo (a rudimentary plant contained in the seed). It is also known as a rootlet.

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.

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.
The legs of a human and the limbs of a cat are similar in structure. These structures are called ______ vestigial homologous analogous structures. This similarity indicates that ________humans evolved from cats cats evolved from the ancestors of humans cats and humans share a common ancestor .
1) A. Vestigial B. Homologous C. analogous
2) A. Humans evolved from cats B. Cats evolved from ancestors of humans C. Cats and humans share a common ancestor.
Answer: The correct answers for the fill in the blanks are-
1) B) Homologous structures.
2)C). Cats and humans share a common ancestor.
Homologous structures/organs are those parts of two organisms that look similar in their form/structure because they share common ancestor (that is they have evolved from a common ancestor) but due to different adaptation, perform different function.
Example -The legs of a human and the limbs of a cat, which have evolved from a common ancestor.

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.

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.
