Convergent is the first blank i don’t know the second i’m sorry.
Options:
A. Analogous structures
B. Vestigial structures
C. Homologous structures
D. Missing links
Analogous structures is the illustration in cephalopod. Thus, the correct option is C.
A cephalopod eye, unlike a vertebrate eye, is focused through movement, similar to a camera or telescope lens, rather than altering shape like a human eye lens. The lens, which is totally internal, is nearly spherical, as is the eye.
<h3>
What are the characteristics of cephalopod?</h3>
- Organs. They have three hearts, two of which transport blood to the gills and the other which pumps blood throughout the body. Their blood is blue because the protein hemocyanin binds oxygen.
- Color. Cephalopods have the ability to change the color of their skin at will. They can even use their skin to create elaborate patterns and forms. This is accomplished by the use of chromatophores, which are pigment-filled bags found in the skin. Nerves can change the color of the skin by controlling these chromatophores.
- Diet. Cephalopods are all carnivorous animals.
Organs, tissues, or cells in the body that are no longer functional in their ancestral version of the trait are known as vestigial organs.

Answer:
The adrenal medulla
Explanation:
The adrenal medulla secretes the catecholamines epinephrine and norepinephrine. The proportion of epinephrine release can vary, but at rest, 80% of adrenal medullary secretion is epinephrine.

The American Psychological Association suggests that you consider seeing a therapist if something is causing you stress and is interfering with some part of your life, especially if: Problems cause embarrassment or avoid others.
I usually enjoy therapy, but there may be a few days when I don't feel like it. It's okay if you don't want to go to therapy. Luckily, there are some things you can do to improve your experience. And there are many other ways to improve mental health outside of therapy.

Answer:
1. Ventricular depolarization −−QRS complex
2. Total time it takes for the ventricular muscle to depolarize and repolarize −−QT interval
3. Atrial depolarization −−P wave
4. Conduction through the atrioventricular (AV) node −−PR segment
5. Ventricular repolarization −−T wave
6. The ventricles are in their depolarized state −−ST segment
7. Conduction through the atrioventricular (AV) bundle −−Q wave
Explanation:
ECG or electrocardiogram is the graphical representation of the heart's rhythm and electrical activity measured by electrical signals. The contraction of the heart shows electrical activity.
There are various deflections shows from baseline and known as specific waves and there are also some flat lines between waves called intervals. This atrial depolarization is called P wave and ventricular repolarization called T wave and the time between ventricular muscles depolarization ( QRS complex) and repolarization is QT interval. Conduction through the atrioventricular (AV) bundle is known as Q wave.
