Answer:

Q3 the right answer is  A) the aluminium pot

QUESTION 4   B. A lake full of water ( also depends on volume and mass of water)

Explanation:

Q3. the specific heat capacity is the amount of heat one gram of substance absorb or release to change temperature by one degree centigrade.

The aluminum  heats faster than the water because it requires less energy to heat it up.

but its also have the radiates/conducts away all of its heat so rapidly that it cools off much faster than anything else.

Q4.

If a swimming pool and lake full of water, both full of water at the same temperature were subjected to the same input of heat energy, the lake  would certainly rise in temperature more quickly than the swimming pool. The heat capacity of an object depends both on its mass and its chemical composition. Because of its much larger mass, the lake full  of water has a larger heat capacity than the swimming pool full of water.

Why does dna replication occur inside the cell?
Brilliant_brown [7]
This is because both strands of DNA have complementary bases. The nucleotide sequence of each automatically gives the needed information to produce its partner. This needed information is Genetic/DNA/Parent Cell. Each cell serves as it's own template in order to acquire this.

Pls help fizzly me confused and ill give you a briliant thingy
Alex73 [517]

Answer:

One difference between these cells is plant cell has chloroplast but animal cell does not have chloroplast.

Another difference between these is that plant cell has cell wall but animal cell does not have cell wall.

Explanation:

Plant cell are known to cells that possess chloroplast. These chloroplast contain chlorophyll which enables the plants to manufacture their own food. Animal cell does not possess chloroplast which makes it impossible for animals to manufacture their own food.

Plant cell actually have cell wall and a cell membrane but animal cell does not have cell wall but only possesses cell membrane. The cell wall gives mechanical strength and maintains cell shape.

There is a population where the frequencies of allele 1 and allele 2 are 0.7 and 0.3, respectively. Allele 1 has a selection coe
Lorico [155]

Answer:

0.8

Explanation:

There is a population where the frequencies of allele 1 and allele 2 are 0.7 and 0.3, respectively

Let's use GG to represent allele 1

Let's use gg to represent allele 2

So we can equally say that;

GG = p = 0.7

gg = q  = 0.3   ( from Hardy-Weinberg Equilibrium)

So, given that the selection coefficient = 0.2

We known that the cross between GG and gg will definitely results to (GG,Gg and gg)

Then the fitness of these genes can be represented as:

1 - s, 1 and 1 - t respectively.

Thus. the allele 1's genotype fitness can be determined as

= 1 - s    ( where s is the selection coefficient)

= 1 - 0.2

= 0.8
