Which structures consist of ectodermal contributions

1 answer:

6 0

The structure that consists of ectodermal contributions is; all neural tissue, including the brain and spinal cord

<h3>What are the structures of ectodermal contributions?</h3>

Ectodermal organs include hair, teeth, and many exocrine glands. They originate from two adjacent tissue layers: the epithelium and the mesenchyme.

Similar sequential and reciprocal interactions between the epithelium and mesenchyme regulate the early steps of development in all ectodermal organs.

The main function of the ectoderm is to form the central nervous system (brain and spinal cord). Following gastrulation, the mesoderm forms the rod-like notochord which signals the adjacent dorsal ectoderm to thicken and form the neural plate.

Thus, the structure that consists of ectodermal contributions is all neural tissue, including the brain and spinal cord

Complete question is;

Which structures consist of ectodermal contributions?

A) all neural tissue, including the brain and spinal cord

B) all components of the lymphatic system

C) urinary bladder and distal portions of the duct system

D) all components of the muscular system

A good rule of thumb is to design the horizontal stabilizer so that its area is about 1/6 to 1/8 of the area of the wing. If the

mars1129 [50]

Answer:

Answer:

Stabilizer with area = 14 cm².

Step-by-step explanation:

Area of the wing = 101.25 cm²

Rule of the thumb is that area of stabilizer must be about 1/6 to 1/8 of the area of wing. So, first we calculate 1/6 of the area of the wing and 1/8 of the area of the wing. Area of stabilizer must be in between these two numbers.

1/6 of the area of wing = \frac{1}{6} \times 101.25 = 16.87561×101.25=16.875

1/8 of the area of wing = \frac{1}{8} \times 101.25 = 12.65681×101.25=12.656

This means, the area of horizontal stabilizer must be in between 12.656 cm² and 16.875 cm². From the given options only one option lies in between these two numbers and that is 14 cm²

Therefore, area of a good stabilizer design from the given options would be 14 cm²

A Japanese bullet train can travel at 300km /h how long will it take to cover a section of track 180 km in length

sweet [91]

Answer:

36 minutes

Explanation:

If we assume that 180 is a fraction of 300, we can simplify it down to 18/30 and then further simplify it to 3/5 (by dividing both by the GCF, 6). It will take 3/5 of an hour for the train to travel 180 km (or 3/5 of the distance it can travel in one hour). 1/5 of an hour is equal to 12 minutes. Therefore 3/5 of an hour is 36 minutes.

Which one of the following is NOT a cognitive technique for stress management

Alinara [238K]

The use of imagery cannot be regarded as a cognitive technique for stress management in individuals and is denoted as option D from the list of available options below.

<h3>What is Cognitive technique?</h3>

These are the different types of ways and method in which our mind and thoughts can be influenced to help manage stress. It requires a mental method of ensuring that the stress doesn't build up and affect us in a negative manner.

Imagery on the other hand involves the creation of images which depicts more work being done instead of easing it which is therefore the reason why it isn't regarded as a cognitive technique for stress management in individuals.

The options include the following:

A - solving problems

b- modifying expectations.

c- maintaining positivity.

d- the use of imagery.
