Answer:
B. A chain of monosaccharides
Explanation:
Polysaccharides, or polycarbohydrates, are the most abundant carbohydrate found in food. They are long chain polymeric carbohydrates composed of monosaccharide units bound together by glycosidic linkages.
Biology help please!!!!
Answer:
Disaccharides are when 2 monosaccharides join together. It is formed by condensation. A water molecule is released. Example include Maltose or sucrose.

When curare, a neuromuscular poison, is dropped onto an isolated muscle-nerve preparation in a laboratory, the muscle does not contract when the nerve is stimulated, even though neurotransmitter is released from the nerve cell. Why does this happen
Answer:
Explanation:
Whenever the nerve terminal's action potential depolarizes, calcium enters the cell through the channels. Calcium allows acetylcholine (ACh) to be released more easily. These ACh molecules subsequently circulate into the synaptic cleft and attach to the motor end-plate of the nicotinic cholinergic receptors. Acetylcholine molecules connect to nicotine ion-channel receptors present on cell membrane the of muscle cells, enabling the ion channels to open. Calcium ions then enter the muscle cell, kicking off a series of events that eventually result in muscular contraction.
Curare is a kind of neuromuscular relaxant blocker that is non-depolarized in nature. Nondepolarizing muscle relaxants work as competitive agonists, binding to ACh receptors but failing to activate ion channels. As a result, they inhibit ACh from bonding, preventing the development of endplate potentials and inducing muscle paralysis.
Excess postexercise oxygen consumption (EPOC) is also known as oxygen debt.
a. True
b. False
Answer:
True.
Explanation:
Excessive postexercise oxygen consumption can also be called oxygen deficit. It occurs after an individual completes a physical activity. Physical effort does not allow oxygen consumption to be normalized as soon as the body comes to rest and for this reason, the body begins to breathe and demand oxygen more intensely. This moment is known as excessive postexercise oxygen consumption, or oxygen debit. The intensity of breathing at this time will depend on the physical effort made, the weight loss and the increase in total caloric expenditure.
What is a plant nucleus
Answer:
All plant cells contain a nucleus, a structure that stores DNA and acts as a cell's command center. It is surrounded by the nuclear envelope and is filled with nucleoplasm. ... DNA is copied during DNA replication for new cells, as well as copied to RNA to make proteins in the nucleus.

A phosphate group has the following chemical composition:
a. -OH
b. -COOH
c. -PS2
d. -CH3
e. -PO4
Answer: The phosphate group has the chemical composition [tex]-PO_{4}[/tex].
Explanation:
A phosphate group is a group where one phosphorus atom is attached to four oxygen atoms.
The oxygen atoms are attached to the phosphorus atom via single bond and one oxygen atom is attached to the phosphorus atom via double bond.
The chemical formula which represents a phosphate group is [tex]-PO_{4}[/tex].
Thus, we can conclude that phosphate group has the chemical composition [tex]-PO_{4}[/tex].

how many homologous pairs of chromosomes are present in a haploid cell that has 8 chromosomes and is in anaphase II of meiosis ll? explain your answer
Answer:
In many ways, meiosis is a lot like mitosis. The cell goes through similar stages and uses similar strategies to organize and separate chromosomes. In meiosis, however, the cell has a more complex task. It still needs to separate sister chromatids (the two halves of a duplicated chromosome), as in mitosis. But it must also separate homologous chromosomes, the similar but nonidentical chromosome pairs an organism receives from its two parents.
These goals are accomplished in meiosis using a two-step division process. Homologue pairs separate during a first round of cell division, called meiosis I. Sister chromatids separate during a second round, called meiosis II.
Since cell division occurs twice during meiosis, one starting cell can produce four gametes (eggs or sperm). In each round of division, cells go through four stages: prophase, metaphase, anaphase, and telophase.

How does the high specific heat of water help maintain the temperature of earth?
A By heating and cooling more slowly than land or air
B. By heating and cooling faster than land or air
с.
By heating faster but cooling more slowly than land or air
The high specific heat of water help maintain the temperature of the Earth by heating and cooling more slowly than land or air. Thus, the correct option is A.
What is the specific heat of water?The specific heat of an object is the amount of heat which is required to increase or raise the temperature of unit mass of that particular substance through one degree celsius. Specific heat is represented by the symbol 'c'. Its unit in SI system is Joule /(kg °C) and in CGS is cal / (gm °C).
The high specific heat of water helps in regulating the rate at which air changes its temperature, which is why the temperature of the planet change between different seasons is gradual rather than sudden, especially the geographical locations near the ocean.
Therefore, the correct option is A.

Back to the cute little pigs. What are the possible parents of the following groups of guinea pigs. Give all possibilities. You do not need to show Punnett Squares, just the possible parents. There may be more than I answer for each. Case 1: 50 % of the offspring are black Case 2: 75 % of the offspring are black Case 3: 50 % of the offspring are hybrid black Case 4: 100 % of the offspring are black Case 5: 100 % of the offspring are white Case 6: 50 % of the offspring are white Case 7: 25 % of the offspring are white
Answer:
Case 1 ⇒ Bb x bb ⇒ F1 = 50% Bb, black + 50% bb, white
Case 2 ⇒ Bb x Bb ⇒ F1 = 75% Black + 25% white
Case 3 ⇒ Bb x Bb ⇒ F1 = 25% BB + 50% Bb + 25% bb
⇒ Bb x bb ⇒ F1 = 50% Bb + 50% bb
Case 4 ⇒ BB x BB ⇒ F1 = 100% BB Black
⇒ Bb x BB ⇒ F1 = 50% BB + 50% Bb = 100% Black
⇒ bb x BB ⇒ F1 = 100% Bb black
