An opening in the dermis through which perspiration reaches the surface of the skin is called pores.

<u>Explanation:</u>

Skin is the second largest organ of the human body. The skin in order to regulate the body temperature expels the liquid in the form of sweat. This sweat is normally not pure water. It is a mixture of water with minerals and salts. This process is called as the perspiration.  Skin has got sweat glands which is present throughout the body.

This sweat gland through  the small holes called pores that expel the sweat. Normally we sweat through arm pits, face, palm of hands and sole of the foot. Women tend to sweat more than men. A normal pure sweat is odorless hence distinctive odor in the sweat can help us identify certain differences the body is undergoing .

Create a food chain that contains four organisms from a producer through three consumers using corn, rabbit, grass, wolf, snake,
inessss [21]

Answer:

Corn → rat → hawk → wolf

Explanation:

A food chain is a linear relationship that shows the feeding pattern of different organisms. The food chain portrays which organism located in one trophic level eats another. A forward arrow (→) is used to show that the organism after the arrow feeds on the organism before the arrow.

Every food chain starts with an organism called PRODUCER, which is capable of supplying the energy that is transferred from one organism to another. The energy moves along organisms called CONSUMERS as they feed on one another. According to this question, the below food chain shows the feeding relationship between four organisms:

Corn → rat → hawk → wolf

Note that, corn is the PRODUCER, while rat, hawk and wolf are CONSUMERS

Answer:

The foramen magnum was not located at the bottom of the skull

Explanation:

The foramen magnum is a large hole or opening found in the base of the skull  through which the spinal cord passes.

The position of the foramen magnum is important since it allows the skull to balance on the body hence essential for posture.

Humans are bipedal and Howler monkeys are quadrupedal hence the positioning of the foreman will be different.

That is how the skull found was realized it was not human

In corn, the allele A allows the deposition of anthocyanin (blue) pigment in the kernels (seeds), while aa plants have yellow ke
lara31 [8.8K]

Answer:

<h2>A) Yes, 12 mu</h2><h2>B) AaWw</h2><h2>C) 0.25%</h2><h2 />

Explanation:

As given,

Allele A for  blue anthocynin.

aa for yellow kernel;

at  second locus;

W produce smooth kernel,

ww for wrinkled kernel;

Parents as given are:  AaWw and aaww

Progeny are:

blue smooth ( AaWw)= 1447;

blue wrinkle (Aaww)= 169;

yellow smooth (aaWw)= 186;

yellow wirnked (aaww)= 1510

a)

Recombinant progeny are  169+ 186= 355

non- recombinant progeny are = 1447+ 1510= 2957

so recombination frequency (RF)= 346/2957×100= 12.0054%

So a and w are linked genes.

They are 12 mu far away from each other.

b) Blue smooth parent= AaWw.

c) Aaww crossed with  aaWw

progeny are= AaWw, Aaww, aaWw, aaww,

They all are produced in same proportion =0.25% or 1/4.
