Answer:
P2O3 y BaO
Explanation:
The oxides of the main group metals are basic in nature. They form alkaline solutions when dissolved in water. Similarly, the oxides of main group non metals form acidic solutions when dissolved in water.
P2O5 is an oxide of a main group nonmetallic element in group 15. We expect this oxide to be acidic and form acids when dissolved in water as expected from the chemistry of the group.
Also, BaO is an oxide of barium, a group two main group metal. Hence we expect this oxide to be basic in nature and form alkaline solutions.
What are two ways the excretory system helps the body maintain homeostasis?
Answer:
1.Osmoregulation
2.Thermoregulation
Explanation:
1.Osmoregulation is the maintenance of constant amount of water in the body of an organism.The kidney is responsible for this phenomenon as in it has a nephron in which at a particular part of the nephron,i.e the conducting tube which sites a hormone called the anti diuretic hormone which makes the walls of the conducting tube permeable to allow the movement of water from the urea back into the body before it is transferred into the bladder for to be released into the external environment.
2.Thermoregulation involves the maintenance of heat in the body of an organism.The skin is responsible for this process.It has hairs which lie on the surface of the skin to loose heat to the external environment during the hot days and also stands on the surface of the skin which trap a film of air on the skin surface to prevent heat loss in the cold days.
I HOPE IT'S OK?
Answer:
The kidneys control the amount of water, ions, and other substances in the blood by excreting more or less of them in urine. The kidneys also secrete hormones that help maintain homeostasis.

The following is a list of the steps that occur in the production of an auditory sensation. 1. The pressure wave distorts the basilar membrane on its way to the round window. 2. Movement of the tympanic membrane causes displacement of the malleus. 3. Displacement of the stereocilia stimulates sensory neurons of the cochlear nerve. 4. Movement of the malleus causes movement of the incus and stapes. 5. Distortion of the basilar membrane forces the hair cells of the organ of Corti toward or away from the tectorial membrane. 6. Movement of the oval window establishes pressure waves in the perilymph of the vestibular duct. The proper sequence for these steps is:___________.A. 2,4,1,6,5,3B. 2,4,6,3,5,1 C. 2,1,4,6,5,3D. 2,4,6,1,5,3E. 2,5,4,6,1,3
Answer:
The correct answer is option D, that is, 2,4,6,1,5,3.
Explanation:
With the approaching of sound waves, ear pinna mediates it towards the external auditory canal, this makes sound waves to reach the tympanic membrane. This results in the vibration of the tympanic membrane, and as the malleus, that is, the first ear ossicle, which is attached to the tympanic membrane gets displaced.
This movement of the malleus further moves the stapes and the incus. As the footplate of the stapes is associated with the oval window, the movement of the oval window takes place. This movement of the oval window creates pressure waves in the vestibular duct's perilymph. The movement of these pressure waves takes place from the Oval window to the Round window.
At the time of this movement, the pressure wave distorts the basilar membrane on its path to the round window, resulting in the vibration of the basilar membrane and the hair cells situated in the membrane against the tectorial membrane.
The stimulation of the sensory neurons takes place in the vestibulocochlear nerve's cochlear branch due to the displacement of the stereocilia. Post this, information reaches the auditory cortex in the temporal lobe's superior temporal gyrus, and hearing takes place.
Option D is the one that shows the correct sequence of steps in an auditory sensation. In this case, the sequence is 2,4,6,1,5 and 3.
We can arrive at this answer because:
At the beginning of auditory sensation, the pinna turns to the external acoustic meatus, directing the sound waves to the tympanic membrane.These waves provoke an intense vibration in the tipanic membrane, which provokes the displacement of the malleus.The displacement of the malleus causes a movement that also displaces the stapes, the incus, and the oval window.The movement of the oval window causes other waves that press against the round window.This causes the basilar membrane and hair cells to vibrate, causing stimulation of sensory neurons.At that point, auditory information reaches the auditory cortex in the temporal lobe, allowing hearing to take place.

Answer:
E
Explanation:
I don't know. How Supposed to help you
Chylomicrons are synthesized in intestinal epithelial cells to transport long-chain triglycerides to the tissues. Therefore, option (A) is correct.
What are chylomicrons?Chylomicrons are lipoprotein particles made up of triglycerides, phospholipids, cholesterol, and proteins. They are also known as extremely low-density lipoproteins. They move dietary lipids from the intestines to other bodily parts.
Chylomicrons deliver lipids ingested from the gut to the adipose, cardiac, and skeletal muscle tissues, where their triglyceride components are digested by the action of the lipoprotein lipase, releasing the free fatty acids that may then be absorbed by the tissues.

When you examine fluid that you have drawn from a blood vessel in someone's arm, you find that it is relatively high in carbon dioxide and waste products. Assuming that the fluid comes from a healthy individual, you conclude that the blood vessel from which you have drawn blood could have been ______.
Answer:
The given blank can be filled with a venule.
Explanation:
A small blood vessel in the microcirculation, which connects the capillary beds to the veins is known as the venules. Various venules combine to form a vein. The walls of a venule are formed of three layers, that is, the inner endothelium formed of squamous endothelial cells, a middle layer of elastic and muscle tissue, and an external layer formed of fibrous connective tissue.
The size of a venule ranges from 8 to 100 micrometers in diameter and are produced when capillaries come in close association. A venule refers to a small blood vessel that permits the deoxygenated blood high in carbon dioxide and waste products to return from capillary beds to the bigger blood vessels known as veins.

B. optic receptors
C. skin receptors
D. taste receptors
Answer:
[tex]\large \boxed{\sf D. \ taste \ receptors}[/tex]
Explanation:
When activated, the receptor most likely prompting the production of saliva is the taste receptor. When food enters the mouth, the salivary glands produce the saliva upon the sensation of taste.
Answer:
Taste receptors.
Explanation:
When activated, the receptor most likely prompting the production of saliva is the taste receptor. When food enters the mouth, the salivary glands produce the saliva upon the sensation of taste. The secretion of saliva (salivation) is mediated by parasympathetic stimulation; acetylcholine is the active neurotransmitter and binds to muscarinic receptors in the glands, leading to increased salivation.

A skin cell of a red fox has 34 chromosomes. You look at the cell under a microscope and see that it has 34 chromosomes and one nucleus. Several hours later, you look at the same cell a second time and see that it has double the amount of DNA and one nucleus. A little while later, you see the cell for a third time and notice that it has 68 chromosomes and two nuclei. What stage of the cell cycle was this cell in when you viewed it at each time point
Answer:
See the answer below
Explanation:
At the first look, the cell was in G1 phase of the cell cycle. At the second look, the cell was in the G2 phase of the cell cycle, and at the third look, the cell was in Telophase.
At the G1 phase of the cell cycle, the cell mainly experiences growth and development. Nothing much happens except that the cell increases in volume.
At the G2 phase of the cell cycle, synthesis of DNA has taken place during the S phase and the amount of DNA present in a cell is doubled at this stage.
At the telophase stage of the cell division in the cell cycle, chromosomes have completed their migration to the poles and each pole appears like a nucleus with their individual chromosomes under the microscope. The cytoplasm is yet to divide at this stage, hence, everything still appears as a single cell.

Galactosemia is an inherited genetic condition. Children with this condition cannot break down the sugar galactose, which is part of lactose. Based on the pedigree chart, is this condition a dominant or a recessive disorder? Explain your reasoning.
Answer:
Recessive.
Explanation:
Galactosemia is an autosomal recessive genetic disorder. Recessive genetic disorders occur when an individual inherits a non-working gene from each parent.
There is no chart attached, so the reasoning is just common scientific knowledge. Please attach the chart so I can properly answer the question!
Answer:
It is recessive. Both parents are heterozygous for the trait, but they do not exhibit the disease themselves. If it were a dominant gene, both parents would have the disease if they carried the gene for it.

An organism that reproduces asexually will have
Answer:
An offspring identical to itself.
Explanation:
The difference between asexually reproduction and sexually reproduction is that when you asexually reproduce, you are simply duplicating yourself. There are many ways you can asexually reproduce, like after a certian growth time, you would just simply split yourself. A part of you can just come off too. The last one is franmentation. It is when you take a big part of you off, and then if it was big enough, it would grow. (Occurs in Starfish). But when you sexually reproduce, two haploids would come together, creating a diploid which would duplicate. And asexually reproduction, you would already start with a full set of genes.
