tresset_1 [31]
I think the answer is dysmorphic ideation because bulimic patient's see themselves in a mirror and are always criticising the way they look..to them they see an overweight person in the mirror, but in reality they could be an ideal weight..

Three lots with parallel side boundaries extend from the avenue to the boulevard as shown answer
larisa86 [58]
Three lots with parallel side boundaries extend from the avenue to the boulevard as shown in the diagram attached.

Given;
            x + y + z = 140 meters


According to the proportion theorem,

\frac{x}{40} = \frac{y}{30}

Solving for x, using cross multiplication:

\frac{x}{1} = \frac{40y}{30}

Similarly,

x/40 = z/35

solving for z by cross multiplication,

z = 35x/40
z = 7x/8

Now, the third proportions,
y/30 = z/35

Solving for y,

y = 30z/35
y = 6z/7

x + y + z = 140

 4y/3 + 6z/7 +  7x/8 = 140

(224y + 144z + 147x)/168 = 140

224y + 144z + 147x = 23520

Substitutoing z = 7x/8,

224y + (144 × 7x/8) + 147x = 23520

224y + 126x + 147x = 23520

224y + 273x = 23520
Now,
Substitute y = 3x/4

(224×3x/4) + 273x = 23520

168x + 273x = 23520

441x = 23520

x = 53.33

Now,
We know that
y = 3x/4
so,
y = 40

And,
z = 7x/8
Z = 46.66

A woman who is a carrier for colour blindness (X-linked recessive) has children with a man who has normal colour vision. A. What
viva [34]

Answer:

Explanation:

The Genotype of the  woman is XCbXN

The man XNY

Since the allele for the color blindness is carried on one of the X -chromosomes of the  carrier mother, then  the male children will be color blind or carrier deopending on the defective gene they inherited. Since they will receive the defective or normal  allele from the  mothers,but the female will carriers or normal because they will inherit either defective allele or normal allele from the mother,but normal  X allele from the father.

Assuming the colorbind gene was inherited by One of the boys, and the girls take the defective genes

1. XNY vs XCbXN.Then the one of the  boys will be colorblind  and the one of  girls will be carriers. XNXCb, XNXN, XCbY,XNY  50 %

2.If the two boys take the effective genes from the mothers. and none of the girls take the defective alelle

Then the two boys will be colorblind and the girls will be carrries XcbY,XcbY and XNXN XNXN.(normal girls).

The proportions that will be  the females  since the girls can only take the defective allele from one of the normal and defective allele from the mother. Assuming the girls  take the defective allele from the mothers and take normal from the father,they will all  be carriers,since the X of the father is normal.

They can not have a color blind girl.Since the father is normal It takes two colorblind X-chromosome to give a girl.

Rocky mountain juniper (juniperus scopulorum) and one-seeded juniper (j. monosperma) have overlapping ranges. pollen grains (whi
bixtya [17]

Answer:

Mechanical isolation

Explanation:

mechanical isolation is a form of prezygotic reproductive barrier, whereby similar species organisms become isolated and unable to successfully interbreed with each other to form zygote, as a result of incompatibility of their reproductive organ or structure, which prevents them from copulating. As a result of this, both species become separated as there is no gene flow between both.

The two species of juniper can be said to be kept separate by <em>mechanical isolation</em>, due to the differences and incompatibility of their reproductive structure.
