chlorine gas (CI) is toxic and sodium (Na) is explosive? yet, together they make common table salt. why do they form a chemical bond?
A)together these two elements form a more stable molecule
B)sodium is a non metal and chlorine is a metal -nonmetals and metals always form a bond
C)chlorine is on the left side of the periodic table in group 1 and these elements always form bonds
D)chlorine has two protons and they transferred to sodium to form the salt molecule
Both ions have complete valence shells and are energetically more stable. I’d assume D because the protons need to transfer.

Which of the following best defines the process of the cells, tissues, organs, and organ systems all working together to maintain a stable internal environment?
Group of answer choices
A. digestion
B.homeostasis
C. excretion
D. disequilibrium
Answer:
Process of the cells, tissues, organs, and organ systems all working together to maintain a stable internal environment are best defined by the term homeostasis (option B).
Explanation:
All living organisms perform their functions properly by maintaining some conditions of the internal environment constant, such as temperature, pH and amount of water or electrolytes. This also guarantees a healthy state and a longer life.
The maintenance of the organic balance is done by an internal regulation system, called homeostasis. Homeostasis means all the processes aimed at preserving the balance and fulfilling the organic functions properly.
The other options are not correct because:
A. Digestion is the process by which nutrients are converted into small molecules that are easily absorbed by the body.
C. Excretion is the process of eliminating waste from metabolic and organic processes.
D. Disequilibrium is the term applied to the failure or loss of ideal conditions or balance.

Write in the Functions of Each Organelle Describe the function of each organelle. Nucleus carries the genes, structures that contain the hereditary information. Nucleoli are small bodies often seen within the nucleus. Ribosome Endoplasmic reticulum Golgi apparatus
Answer:
Explanation:
Ribosome works with ribonucleic acid to produce a functional protein. Translation takes place at the ribosome.
The endoplasmic reticulum helps in transport of proteins that are made by the ribosomes and folds them into sacs that are called cisternae from where it is moved to the Golgi apparatus.
Golgi apparatus served as store house for molecules that moved from endoplasmic reticulum. They are then released from the Golgi apparatus in what are called secretory vesicles into the cytoplasm.
Answer:
See the answer below
Explanation:
The nucleus is a double membrane organelle that is responsible for controlling the activities of the cell. It contains the DNA which carries the gene and the hereditary information of the cell.
The nucleoli are small spherical structures that are located within the nucleus which function in the formation of the ribosome and hence, important for protein synthesis in the eukaryotic organisms.
The ribosomes are structures within the cell which represent the site of protein synthesis. During protein synthesis, the mRNA and the tRNA attach themselves to the ribosome to form the translation complex for the initiation of protein synthesis.
The Golgi apparatus is a system of membrane responsible for the packaging and secretion of proteins and lipids within the cell.

draw a well labelled diagram of a leaf structure and explain how the stomata ,the cuticle and the vascular bundle works
Answer:
A well labelled diagram of a leaf structure
Explanation:
Answer:
Vascular bundles are a collection of tube-like tissues that flow through plants, transporting critical substances to various parts of the plant.The cuticle reduces the rate of water loss from the leaf surface.Stomata are tiny holes found in the underside of leaves. They control water loss and gas exchange by opening and closing. They allow water vapour and oxygen out of the leaf and carbon dioxide into the leaf.Which of the following is a scientific question? (Apex)
A.
Why dont people eat more dolphin meat.
B.
Should commercial fisheries be regulated to protect dolphin habitats.
C.
Are dolphins more interesting than whales
D.
Do dolphins emit characteristics whistles in response to their offspring
Answer:
D
Explanation:
D is the answer because the other ones are based on opinions.
The option that reveals the scientific question is as follows:
Do dolphins emit characteristic whistles in response to their offspring?Thus, the correct option is D.
What is a Scientific question?Scientific questions may be defined as questions that may direct to a hypothesis and assist us in answering or figuring out the reason for some observation.
In this scientific question, the response of dolphins is estimated with respect to their offspring is considered. This is illustrated as compared to controlled conditions as well in order to predict something conclusive.
The rest of the options are simply displaying the characteristics of opinions that may be analyzed but do not express valid and accurate scientific questions. Such options also determine the fact of interest over scientific understanding and analysis.
Therefore, the correct option for this question is D.

fingerprint patterns that form complete circles are known as:
A. whorls
B. irregulars
C. arches
D. tented arches
Answer:
whorls
Explanation:
Whorls. Whorls represent 34 percent of all fingerprint patterns. At least one ridge in a plain whorl pattern makes a complete circuit in the form of a circle, oval or spiral, and there must be at least two triangular shapes called deltas. ... Central pocket loop whorls make a complete circle inside the two deltas.

Two photographers take time-lapse photos of the night sky. One of them is at the equator. The other is at the south pole. Which photo will show stars that never rise or set? Explain
Answer: South pole.
Explanation:
The equator is filled with non-circumpolar stars which means the stars sets in the sky. The north and south pole is full of circumpolar stars which means they never set.
If two photographers take time-lapse photos of the night sky with one being at the equator and the other at the south pole, the photo by the photographer at the south pole will show stars that never rise or set.
The stars that never rise or set is known as the circumpolar stars and are usually found close to either of the earth's poles - north or south pole.
This means that the photographer at the equator which is an equidistance from the two poles will not be able to capture the circumpolar stars.

Crossing over occurs when (4 points)
Answer:
Crossing over is the exchange of genetic material between non-sister chromatids of homologous chromosomes during meiosis, which results in new allelic combinations in the daughter cells.
When chromosomal homologs communicate with one another during Meiosis I's metaphase, crossing over takes place.
What is Crossing over?When chromosomes of the same type are paired together during meiosis, a biological event called crossing over takes place.
Parts of the chromosome can be exchanged when two chromosomes, one from the mother and one from the father, line up. The same genes may be present on the two chromosomes in different versions.
The exchange of genetic material between non-sister chromatids of homologous chromosomes occurs during crossing over, an enzyme-mediated process. It happens during meiotic prophase I's pachytene stage.
Crossing over occurs during Meiosis I's metaphase when chromosomal homologs interact with one another.
Thus, this way, crossing over takes place during meiosis.

Describe two pathways the student can use to show how a metamorphic rock
could become another type of rock and then become metamorphic once again
Answer:
In order for a metamorphic rock to become a sedimentary rock, the rock must undergo erosion. Once the rock has eroded, it will produce rock fragments or sediments which accumulate to form a sedimentary rock. ... In turn, when igneous and sedimentary rocks are exposed to heat and pressure, the rocks become metamorphic.
Explanation:
hope this helps
Answer:
One pathway is that an igneous rock can apply heat and pressure to the rock which will become metamorphic. Another pathway is that a metamorphic rock can be changed by heat and pressure to form into a different metamorphic rock.
Where is the main store of phosphorus ?
Answer:
Phosphorus is most commonly found in rock formations and ocean sediments as phosphate salts.
Answer:
The largest reservoir of phosphorus is in sedimentary rock. It is in these rocks where the phosphorus cycle begins. When it rains, phosphates are removed from the rocks (via weathering) and are distributed throughout both soils and water. Plants take up the phosphate ions from the soil.
