Whoever gets it right first gets brainliest

In a plant, leaf color and leaf shape are controlled by two linked genes Leaves of the wild-type plant are red. A recessive muta

Brrunno [24]

Solution :

Red is dominant over the white leaves and pointed is dominant over smooth.

Red = R , white = r

Pointed = P , smooth = p

Red, pointed x white,smooth ------ Parents

RRPP rrpp

RP rp ----------------- Gametes

RrPp -------- $F_1$

(red, pointed)

When this $F_1$ is test crossed,

RrPp x rrpp ---- $F_1$ test cross

Gametes → rp

RP ---------- RrPp - red, pointed - 36 parental type

Rp ---------- Rprp - red, smooth - 14 re- combination

rP ----------- rrPp - white pointed - 10 re- combination

rp ----------- rrpp - white, smooth - 40 - parental type

Total = 100

As this ratio is deviating from 1:1:1:1, it indicated the two genes are linked.

Linkage strength = percentage of crossing over = map distance between the genes.

Percentage crossing = recombination frequency = percentage of recombination.

Recombination frequency $=\frac{\text{total no. of recombination}}{\text{total no. of progeny}}\times 100$

$=\frac{14+10}{100} \times 100$

= 24 %

= 24 map units

Is flooding a natural part of the water cycle

bearhunter [10]

Answer: Floods are a natural part of the water cycle, but they can be terrifying forces of destruction. ... Floods usually occur when precipitation falls more quickly than that water can be absorbed into the ground or carried away by rivers or streams.

2,4-dinitrophenol (DNP) is a weak acid that can diffuse across lipid membranes. When added to eukaryotic cells, DNP can enter th

Murljashka [212]

Answer:

a. In the presence of 2,4 dinitrophenol, which is soluble through the lipid membranes, the H+ gets an another route to pass through the membrane. It hampers the proton gradient potential without any generation of ATP. The gradient that was being utilized for the generation of energy is now just lost in the form of heat.

b. With the reduction in the generation of energy, the cells get devoid of ATP, and drive the electron transport chain intensely so that the collapsing proton gradient gets re-established. However, it prevents the ATP synthase by providing a different path to the proton ions and thus diminishing the H+ concentration gradient.

pochemuha

The three parts that make up paint are pigments, binders and solvents. Pigments consist generally of organic and non-organic compounds and materials that are added to paint to produce a particular color. Binders are substances that provide support or structure for the pigment and solvents to work. Solvents work to dissolve or disperse these substances into liquid form.
Polymers are a group of atoms that form in repetitious patterns The scanning electron microscope is a microscope that works by shooting beams of electrons at the slide and recording the emissions of the electrons. One advantage is that it has much better magnification than other microscopes
