Answer:

an autosomal recessive disorder

Explanation:

Autosomal recessive disorders are inherited diseases caused by the presence of two copies (alleles) of an abnormal gene, thereby only homo-zygous recessive individuals are affected by this type of disease. In consequence, although both parents don't express the disease, they can be carriers and pass this recessive disorder to their offspring who express the disease. In this case, the pedigree shows that heterozygous parents are not affected but they are carriers of the recessive allele for this disease, thereby some offspring express the trait. The black circle (female) and the black square (male) indicate affected individuals in the pedigree chart. Since both parents are heterozygous, 1/4 (25%) of all offspring would be expected to have the autosomal recessive disorder.

Alexandra [31]

Answer:

c. our inhibitions and insecurities

Explanation:

The factors that influence what stimuli we notice and try to make sense of are

1. When some certain characteristics of external phenomena attracts our attention. There is an higher chance of noticing it --- things that STAND OUT.✔

2. An individual perception is controlled and regulated by the acuity of his/her senses.

Take for example, a person with a better sense of smell, its more attracted to the aroma of a freshly baked chocolate cake than others -----acuity of our senses.✔

3. Change or variation attracts attention, as this explains why one might ignore a friend's chat but will swiftly notice when his/her friend is tensed. --- Change or variation✔

4. What an individual choose to notice is also regulated by their personality and inner thoughts as morives play a important role in what we see and miss out on.

5. An individual perceive what he wants to perceive ----- the self-fulfilling prophecy (deals with individuality and perception of one's self)

Kindly note that the option c -our inhibitions and insecurities- does not influence what stimuli we notice and try to make sense of.

Answer:

Hewo! Mizuki here to help! The correct answer would be option A!

Explanation:

Oki! So.... we find out the length, width, and height first!

The equation for finding the length: 36 ÷ 2

And the answer will be 18, make sure to memo it if your following along!

The equation for finding width: 36 ÷ 3

And the answer will be 12, so yeah(I tried it with 2 because it was 2 prism long, but it turned out to be a number not on the list [3888])

The equation for finding height: 24 ÷ 2

And the answer will be 12!

Soo... we multiply the length, width, and height!

18 x 12 x 12 = 2592

Since 2592 in on the list, that will be your answer!

1. List the adaptation that ALL vertebrates have in common.
The vertebrate is a subphylum of kingdom Animalia. The member of subphylum should have a spine or vertebrae. Therefore, all vertebrates should have vertebrae. All the member should have all the classification above the subphylum like cranium from craniate and notochord from chordate.

2. List all the adaptations that your chordate has (as shown on the cladogram).
The frog is part of Amphibian that shown on green lines. It should have all the organ above its classification such as jaws and paired appendages, lungs(frog can live in the land), four limbs. It also has all the trait of vertebrates that was described above.

3. To which type of chordate is your chordate most closely related?
If your chosen chordates are the frog, then salamander and caecilian would be the most closely related chordates. The reason is that salamanders and caecilians are also amphibians like the frog, which means they have all the trait from amphibians.

4. Why do you think endothermy appears at two points on the cladogram?
Endothermy member is the chordates that have warm blood. There are two chordates that have warm blood in the cladogram, the apes(mammals) and the bird. Since the bird is classified as reptile the but the ape classified as mammals, the cladogram needs to put two endothermy.

5. Amniotic eggs have a waterproof membrane. What type of animals evolved from animals that lay amniotic eggs?
The amniotic eggs will be found on the reptile. The eggs have a waterproof membrane to prevent water comes out of the egg. Water is an important resource and if a high amount of water leak from the egg, the egg will be dried out and die. 

6. In what type of habitat do you think the evolution of amniotic eggs helped animals survive? Hint: In what habitat do all animals without amniotic eggs live?
The amniotic eggs help an animal that lives on the dry land to make offspring. All of the animals before reptiles are living in the water and spawn their eggs there so there is no concern about losing water, thus waterproof membrane is not needed. Reptile spawns their eggs on land, so it needs a method to contain the water.
