(Fossils provide scientists with evidence that allows them to hypothesize how living organisms have evolved over time. Tiktaalik roseae was a unique organism that has been nicknamed the “fishapod” because it is believed to be a species had traits of both fish and tetrapods, the first four-legged animals.)
Which evidence would scientist use to make the connection between ancestry of fish and tetrapods using Tiktaalik roseae?
-using transitional forms
-using relative dating
-studying decreasing complexity
-studying analogous structures
Answer:
A. using transitional forms
Explanation:
On Edge 2020
Using transitional forms is the evidence scientist use to make the connection between ancestry of fish and tetrapods using Tiktaalik roseae.
What is Transitional forms?This is referred as the remains of a life form that exhibits traits common to both an ancestral group and its derived descendant group.
The transitional form which is option A is mostly suited as the organisms involved have common traits.

Look at the diagram of the male reproductive system. Name the parts
Answer:
Explanation:
مرحبًا ، أود أن أحاول مساعدتك في عملك المدرسي. إذا كنت تستطيع أن تشرح أكثر فأنا أقدر ذلك.
The diagram of the male reproductive system. The parts names are 1. prostate gland, 2. Pe.nis, 3. Urethra, 4. Vas deference, 5. testis, 6. scrotum .
The biological process of creating offspring of the same sort is known as reproduction. It is one of the critical mechanisms that ensures the survival of the species generation after generation.
The testes, scrotum, spermatic ducts, male accessory glands, and pe.nis comprise the male reproductive system. All of these organs collaborate to make sperm, the male gamete, male sex hormones, and other semen components.
Pe.nis: It refers to the male genitalia. It consists of three cylindrical chambers filled with erectile tissue. The two larger ones, the corpora cavernosa, are side by side, and the third is the sinus, called the corpus spongiosum, which covers the urethra.
Scrotum: It is a thick skin sac that protects and surrounds the testicles. It also regulates the temperature of the testes, which must be slightly lower than body temperature in order to produce appropriate sperm.
Testes: In humans, there are two testes. The testes are located outside the body in a pouch known as the scrotum. They have oval bodies that are 4 to 5 cm long and 2 to 3 cm wide.
Male sex accessory ducts are known as vas deferens.
Urethra: It is a tube-like structure that connects the urine bladder and urinary meatus.
The male accessory glands produce fluid that feeds the sperm. It is known as seminal plasma. This fluid contains a lot of fructose, calcium, and enzymes. It is the largest volume of semen from which the sperm is released during ejaculation.
Thus, The parts names are 1. prostate gland 2. Pe.nis 3. Urethra 4. Vas deference 5. testis 6. scrotum .

The two divisions of nervous system are central nervous system and peripheral nervous system.
The system takes in information through the senses.
Explanation:
Given example is that if you touch a hot stove, the senses of the skin brings the message of pain to your brain. The brain then sends a message back telling the muscles in your hand to pull your hand away and this is when the reflex action takes place. This is called the reflex action.

Match each movement with the correct label.
flexion
extension
adduction
abduction
elevation
depression
medial rotation
lateral rotation
Answer:
flexion - depression
extension - elevation
adduction - medial rotation
abduction - lateral rotation
Explanation:
Flexion is the process of bending an arm or leg. It occurs as a result of the contraction of the muscles. Depression is a downward movement. Hence, flexion refers to the depression of an arm or leg.
Extension is the process of stretching the body parts. Elevation is an upward movement. Hence, extension refers to the elevation of body parts.
Adduction is the movement of a limb or other part of the body towards the midline or another part of the body. The movement of the limb towards the midline of the body is known as medial rotation.
Abduction is the movement of a limb or other part of the body away from the midline of the body. The movement of the limb away from the midline of the body is known as lateral rotation.

In cats, the bones in the legs involved in
walking are very similar to the bones of
whales' flippers that are involved in
swimming. These are examples of -
F: analogous structures
G: homologous structures
H: vestigial structures
J: endosymbiosis
Answers: G
Answer:
Your answer is most likely G), so you are correct.
These are the example of Homologous structure. So, the correct option is (G).
What are different types of structures?Homologous structures are similar in structure and location, but perform different functions, resulting in divergent evolution. For example, An arm of a human, the leg of a dog or a flipper of a whale are all homologous structures.
Analogous structures are similar in function but have different origins and structures resulting in convergent evolution. For example, from wings in birds, bats and insects to fins in penguins and fishes are all analogous structures.
Structures with similar anatomy, morphology, embryology, and genetics, but dissimilar functions are known as homologous structures, while structures that are superficially similar but perform the same physiological function are referred to as analogous structures.
Thus. these are the example of Homologous structure. So, the correct option is (G).
