Is it conceivable that these two reagents would react with each other? what experimental evidence do you have to support your answer?

Answers

Under controlled conditions, sodium bromide and hydrogen peroxide are actually able to react. However in this experiment, I do not believe that they would react. This is due to the presence of other compounds which are used in the reaction and the means by which the compounds were added to the solution. There are actually a few clues that can tell us whether they are reacting. The most obvious one is that there would be bubbling due to production of H2 gas.

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

Answers

the correct answer to your question is A, first, sun and core of the earth I hope this helps you out, let me know if its right. Im 100% I am. 

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.

Part c - how does phospholipid structure relate to the selective permeability of the plasma membrane?

Answers

One of the reasons the plasma membrane can have selective permeability it's because it's composed by a bi-layer of phospholipids.
The interaction between them and other molecules will influence how these molecules will cross the membrane. If the molecule it's hydrophobic it can easily cross, if it's polar molecules and ions( hydrophilic), they cannot cross easily.

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

Answers

The nurse should calculate the correction dose the patient should take.

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.

Most people think babies are equally likely to come as either a boy or a girl. this is not true. actually, about 51.3% of all babies are boys. if a family has two children (not twins), what is the chance they have one boy and one girl? round your answer to two decimal places.

Answers

49.97% For this problem, let's consider the probability of each of the four possibilities for having two children, being BB, BG, GB, and GG. Then sum the probabilities for both the BG and GB events. So BB = 51.3% * 51.3% = 26.3169% BG = 51.3% * 48.7% = 24.9831% GB = 48.7% * 51.3% = 24.9831% GG = 48.7% * 48.7% = 23.7169% If you check, you'll notice that the sum of all the probabilities add up to 100% like it should. And the sum of BG + GB is 24.9831% + 24.9831% = 49.9662% which when rounded to 2 decimal places is 49.97%

How many moles of O2 are required for the complete reaction of 88.9 g of C2H4 to form CO2 and H2O?

Answers

The molecular mass for C2H4 should be: 2*12 + 4*1= 28 gram/mol. Then the amount of mol in 88.9 grams C2H4 should be: 88.9g/ (28g/mol)= 3.175 mol.

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

Why was the evolution of vascular tissue important to plants conquering the land?

Answers

Vascular tissue includes xylem and phloem tissues. Xylem tissue carries water and minerals from the roots and distribute it in the plant body to the tip. Phloem tissue is mainly responsible for transporting food (glucose) from leaves to the roots and all parts of the plant body. These two tissues are very important for the plants to conquer land because without these, plants cannot distribute water and food to the other parts.
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.

The presence of chondrocytes indicates that a tissue is ________.

Answers

Producing cartilaginous matrix.

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 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

The correct option is A.
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.

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.
