How do most animals produce offspring
Answer:
Some animals produce offspring through asexual reproduction while other animals produce offspring through sexual reproduction. Both methods have advantages and disadvantages. Asexual reproduction produces offspring that are genetically identical to the parent because the offspring are all clones of the original parent.

why do you think they stilk proruxe bright flowers to attract bees?
Answer:
A
Explanation:
In order for plants to entice pollinators, they must first offer their favorite foods: nectar and protein. Since most pollinators fly, the colors of a flower must attract them; therefore, the brighter the flower, the more likely it will be visited. ... For instance, bees are attracted to bright blue and violet colors.

What are ions?
An ion is defined as an atom or a molecule which has a net electrical charge. There are 2 types of ions :1) cation 2) anion . The cation is the positively charged ion and anion is the negatively charged ion . As they are oppositely charged they attract each resulting in the formation of ionic bond.
Ions consisting of single atom are mono-atomic ions while which consists of two or more ions are called as poly-atomic ions . They are created by chemical interactions . They are very reactive in their gaseous state and rapidly react with oppositely charged ions resulting in neutral molecules.Ions are generated on dissociation.

True
Or
False
Answer:
[tex]\boxed {\boxed {\sf False}}[/tex]
Explanation:
Kinetic energy is the energy of movement or energy at work. An example is a ball rolling down a hill.
Potential energy is stored energy due to the position of an object. For example, a ball resting at the top of a hill.
The question incorrectly described potential energy as kinetic energy. Therefore, the answer is false.
How do you negatively affect the ecosystem of the Great Lakes area?
Answer:
Threats to the Great Lakes' ecosystems, include invasive species, climate change, pollution, and habitat destruction. Climate change affects water temperatures, weather patterns, and lake levels. Pollutants from residential, agricultural, and industrial areas reduce water quality.
Explanation:
I hope this helps answer your question
:D
Answer:
Other human activities that have had an impact on the Great Lakes include intentional water level regulation, man-made alterations such as dredging, diversions, and water withdrawals, which have resulted in earlier thawing of the lakes, lower water levels, and, of course, the spread of industrial waste.

O True
O False
Answer:
True
Explanation:
Carbon is the backbone of life on Earth. Most of Earth's carbon, about 65,500 billion metric tons is stored in rocks. The rest is in the ocean, atmosphere, plants, soil, and fossil fuels. Carbon flows between each reservoir in an exchange called the carbon cycle, which has slow and fast components.
Choose the correct statement.
A) Anions gain electrons having a charge of positive.
B) Cations lose electrons having a charge of positive
C)Cations lose electrons having a charge of negative.
D)Anions gain electrons having a charge of neutral.
Answer:
B) Cations lose electrons having a charge of positive.
Explanation:
Hello there!
In this case, it is widely known that ions are classified as positive cations and negative anions, since the former is produced when a metal loses electrons and the latter when a nonmetal gains electrons; in such a way, the correct choice is:
B) Cations lose electrons having a charge of positive.

5.478 grams of potassium acetate and 2.143 grams of iron(III) hydroxide are added to a beaker containing 100.0 mL of water and stirred vigorously. A solid settles to the bottom of the beaker. If the water is decanted and the solid is dried, what is the maximum mass of solid that should be recovered
Solution :
[tex]$Fe(OH)_3+3CH_3COOK \rightarrow Fe(CH_3COO)_3 + 3KOH$[/tex]
(iron (potassium
hydroxide) acetate)
Number of moles of [tex]$Fe(OH)_3 = \frac{\text{mass of }Fe(OH)_3}{\text{molar mass of }Fe(OH)_3}$[/tex]
[tex]$=\frac{2.143 \ g}{106.867 \ g/mol}$[/tex]
= 0.02005 mol
Number of moles of [tex]$CH_3COOK = \frac{\text{mass of }CH_3COOK}{\text{molar mass of }CH_3COOK}$[/tex]
[tex]$=\frac{5.478 \ g}{98.15 \ g/mol}$[/tex]
= 0.0585 mol
Since 1 mol of [tex]$Fe(OH)_3$[/tex] reacts with 3 mols of [tex]$CH_3COOK$[/tex]
Therefore, number of moles of [tex]$CH_3COOK$[/tex] reacted [tex]$=\frac{0.0585}{3 }$[/tex] mol
= 0.0195 mol
Therefore the limiting reagent is [tex]$CH_3COOK$[/tex] and hence the number of moles of [tex]$Fe(CH_3COO)_3$[/tex] produced is 0.0195 mol
Amount of [tex]$Fe(CH_3COO)_3$[/tex] produced = moles x molar mass
= 0.0195 moles x 232.98 g/mol
= 4.5431 g

Answer:
1.69 g/cm³
Explanation:
Mass (m) = 22 g
volume (v) = 13 cm³
density (d) = ?
we know density is defined as mass per unit volume
d = m/v
= 22 / 13
= 1.69 g/cm³

which statement describes the energy and bonding changes as two atoms of fluorine become a molecule of fluorine?
Statement that gives description as regards energy and bonding changes between atoms such as fluorine become a molecule of fluorine, bond Energy is released as a bond is formed. Thus option 4 is correct.
What is bond energy ?The Bond Energy otherwise called as bond enthalpy is a quantity that offers insight into the strength of a chemical bond.
The ‘bond energy’ can also be represented as “the average value obtained from the bond dissociation enthalpies of all the chemical bonds in a given chemical compound.
The bond energy of a chemical bond is directly proportional to the stability of that bond which implies that the greater the bond energy o between two atoms, the greater the stability of that chemical bond.

Argon makes up about 0.93% of our atmosphere. If the atmospheric pressure is 760 mm Hg, what is the pressure contributed by argon?
Answer:
[tex]P_{Ar}=7.068mmHg[/tex]
Explanation:
Hello!
In this case, according to the given percent of argon in our atmosphere, it is possible to compute the pressure contributed by it as shown below:
[tex]P_{Ar}=P_{atm}*0.93\%[/tex]
Thus, we plug in to obtain:
[tex]P_{Ar}=760mmHg*0.0093\\\\P_{Ar}=7.068mmHg[/tex]
Best regards!
The pressure of the argon gas will be equal to [tex]P_{Ar}=7.068 \rm\ mmHg[/tex]
What will be the pressure of the argon gas?Pressure is defined as the normal force acting on any surface in the case of gases it is the normal force acting on the surface of the earth.
now it is given in the question that the Argon contains 0.93% part in the atmosphere.
So here are the calculations
[tex]\rm P_{Ar}=P_{Atm}\times 0.93[/tex]%
[tex]\rm P_{Ar}=700\times 0.93[/tex]%
[tex]\rm P_{Ar}=7.068\ mmHg[/tex]
Thus the pressure of the argon gas will be equal to [tex]P_{Ar}=7.068 \rm\ mmHg[/tex]
