What are two conclusions that Mendal made about his research on genetics

The two conclusions that Mendal made about his research on genetics depended on the law of segregation and law of independent assortment.

Explanation:

The “law of segregation” says that, pairing of genes (alleles) take place in each parent. During split up, one gene is only passed from each parent to the offspring. But which particular gene is passed is is not know and is completely up to chance.

The “law of independent assortment” states, from all pairs of gene each offspring receives different pair of gene independently. Thus, when a gene is inheritant at one location in a genome it is not necessary that it should influence the inheritance of a gene in another location.

A sample of sand, 5cm in diameter and 10 cm long, was prepared at a porosity of 50% in a constant head apparatus. The total head

GarryVolchara [31]

Answer:

$K = 2.037*10^{-3} m/s$

$V_s = 0.0122 \ m/s$

Explanation:

Given that;

diameter (d) = 10cm/2 = 0.1m/2 = 0.05 m

length (l) = 10 cm = 0.1 m

porosity = 50%

height (h) = 30 cm = 0.3 m

time (t) = 5 s

volume (v) = 60 cm³ = 60 × 10⁻⁶ m³

Q (flow rate) = $\frac{v}{t}$

Q = $\frac{60*10^{-6} m^3}{5}$

Q = $12*10^{-6} m^3 /sec$

From constant head method, we use the relation K = $(\frac{Q*L}{A*h})$ to determine the hydraulic conductivity ; we have:

$K = \frac{12*10^{-6}*0.1}{\frac{\pi}{4}0.05^2*0.3}$

$K = 0.002037\\\\K = 2.037*10^{-3} m/s$

Seepage velocity $V_s = \frac{velocity }{porosity}$

where; velocity = $K*i$

= $(2.037*10^{-3}*)(\frac{0.3}{0.1})$

= $6.111*10^{-3} m/s$

$V_s = \frac{6.111*10^{-3}}{0.5}$

$V_s = 0.0122 \ m/s$

V1T2 = V2T1 is an expression of who’s law

Andru [333]

<u>Answer:</u>

It is the expression of Charles' Law.

<u>Explanation:</u>

The given expression V1T2 = V2T1 is the formula for the Charles' Law.

A special case of an ideal gas is named as the Charles' Law. This law applies to ideal gases only which are at constant pressure.

According to this law, the volume of a fixed mass of a gas is directly proportional to its temperature and is given by:

V1T2 = V2T1
