Complete question:
You will find the image of the skulls in the attached files.
Answer:
1) 2 similarities between each of the skulls might be the presence of the nasal spine, and the interdental space.
2) The size of the skull seems to be the most noticeable change in skull anatomy between the dawn horse and the modern horse.
Explanation:
- Each of the nasal bones in horses ends in a protuberance named "the nasal spine". These spines converge in the distal portion of the bone. These spines and the incisive bone delimitates the space called the naso-incisor notch. In the attached figure you will see the nasal bone in red and the nasal spines. This structure is present in all the skulls in the same position.
- The interdental space is the space left between the front teeth and the back teeth. It is useful to recognize a male from a female in modern horses. This space can be found in all the skulls. You will see it in blue in the image.
The biggest change in skulls between the dawn horse and the modern horse is the size. The skull keeps the original shape or very similar shape but varies in length and height.
Answer:
A
If the level of thyroxine in the blood is high then the pituitary gland releases less TSH. Therefore, a low level of TSH means that your thyroid gland is overactive and is making too much thyroxine. Thyroxine (T4). A high level of T4 confirms hyperthyroidism
Answer:
The correct answer is d. plasma membrane
Explanation:
Bacteria do not have membrane-enclosed organelle like mitochondria to generate ATP but even then it produces ATP because in bacterial plasma membrane acts as the machinery of ATP synthesis.
The ATP synthesis in bacteria is the same as eukaryotes. In prokaryotes, the plasma membrane consists of an electron transport system and NADH helps in building the proton gradient across the plasma membrane.
Then after the proton gradient is built in the plasma membrane the proton tends to come back into the cytoplasm through the ATP synthase complex which generates ATP from ADP and inorganic phosphate.
Therefore the correct answer is d. plasma membrane.
Answer:
The amount of energy of a wave can be determined by measuring its wavelength, the distance between consecutive points of a wave.
Visible light is a type of radiant energy within the electromagnetic spectrum; other types of electromagnetic radiation include UV, infrared, gamma, and radio rays as well as X-rays.
The difference between wavelengths relates to the amount of energy carried by them; short, tight waves carry more energy than long, wide waves.
