Answer: A tick on a deer
Explanation:
because commensalism is a type of symbiotic relationship in which one species benefits, while the other species is neither harmed nor helped
please put brainlest for me if you found this helpful
An example of commensalism is tick on a deer. Therefore, option A is correct.
What is commensalism ?Another sort of symbiotic interaction is commensalism, in which one organism benefits and the other does not in any way suffer. Golden jackals will pursue tigers as they hunt in order to consume the tigers' leftovers.
The term "commensalism" is derived from the word "commensal," which in human social interaction refers to "eating at the same table," and which itself is derived through French from the Medieval Latin term "commensalis," which refers to "sharing a table," from the prefix com-, which means "together," and mensa, which refers to "table" or "meal."
The simplest definition of commensalism is that it is a form of symbiosis in which one organism gains while the other neither gains nor suffers harm. The three primary forms of commensalism are phoresy, metabiosis, and inquilinism.
Thus, option A is correct.

Among the given reactions,
a. Ag+FeCl 3
b, Zn + CaO
C. Ba+Na 2 CO 3
d . Cr+KNO3
which reaction is likely to take place based on the reactivity series?
Explanation:
The metal reactivity series is:
Li > K> Ba >Ca>Na > Mn > Zn > Cr> Fe> Cd Ni > H > Sb > Cu > Ag > Pd > Hg > Pt
The highly reactive metal will displace the less reactive metal from its compound during a displacement reaction.
a. Ag+FeCl 3
Ag is less reactive than Fe, so Ag cannot displace Fe from its compound.
This reaction also does not occur.
b, Zn + CaO
Zn is less reactive than Ca, so it cannot displace Ca from its compound.
This reaction does not occur.
C. Ba+Na 2 CO 3
Ba is more reactive than Na, so Ba displaces Na from its compound.
This reaction is possible.
d . Cr+KNO3
Cr is less reactive than K, so it cannot displace K from its compound.
Hence, This reaction is not possible.

Explanation:
In positron emission, a proton is converted into a neutron and a positron. An anti neutrino is a particle that serves the purpose of balancing the spins.
During positron emission, the mass number to the daughter nucleus is the same as that of the parent nucleus but the atomic number of the daughter nucleus is less than that of the parent nucleus by one unit.
Positron emission increases the neutron/proton ratio.

There are on average 43 g of sugar and 355 mL can of soda please calculate the molarity of sugar in the can of soda the molar mass of sugar is 342.2 g/mol
Answers
Explanation:
Given :
Amount of solute - sucrose (C12H22O11) = 41 g
Amount of solvent -soda = 355-mL
Molarity of the solution with respect to sucrose= ?
Molarity(M) is a unit of concentration measuring the number of moles of a solute per liter of solution. The SI unit of molarity is mol/L.
Formula to find the molarity of solution :
Molarity =
Amount of solvent is given in mL, let’s convert to L :
1 L = 1000 mL
Therefore, 355 mL in L will be :
= 0.355 L
We have the amount of solute in g, let’s calculate the number of moles first :
Number of moles (n) =
Molar mass of C12H22O11 = 342.29 g/mol.
Therefore, n =
= 0.119 moles.

Which statements are correct regarding the Law of Conservation of Matter and Energy?
Matter or energy can create itself.

Matter or energy can change from one form to the other.
The law agrees with the Biblical account of Creation
(more than one answer)
Answers
Answer:
Matter or energy can change from one form to the other
Explanation:
The law of conservation of energy states that energy can neither be created nor destroyed but can only be transformed i.e. changed from one form to another. For example, mechanical energy can be changed to electrical energy.
Likewise, the law of conservation of mass/matter states that matter can not be destroyed or created but can change via physical or chemical means to conserve it. For example, matter can change from liquid state to gaseous state.
From the above two laws, it can be said that "matter or energy can change from one form to the other".
