I think it's (c). Evidence suggests they were the first plants
Explanation
Evidence shows that plants evolved from freshwater green algae, a protist
There's similarities between green algae and plants .both plants and green algae contain the same form of chlorophyll.
but land plant are multicellular and autotrophic
The most important discovery by him, the telescope changed our vision on the universe.
E. Crossing a red flower with a white flower yields a pink flower
The hypothesis of blending inheritance states that the traits received by an organism resulting from sexual reproduction are intermediate between the traits of its parents. In this case, one parent was red and the other was white, and the offspring got the intermediate trait, which was pink.
<h2>Answer is "true" statement</h2>
Explanation:
- Each osteon is made out of concentric rings of a calcified network called lamellae (solitary = lamella)
- the lacunae and osteocytes are found in a grid-like system of network spikes called trabeculae (particular = trabecula) (Figure (Links to an outer site.)). The trabeculae may give off an impression of being an irregular system, however every trabecula shapes along lines of worry to give solidarity deep down.
- This system of flat bones consist of spongy bone permits supplements to be moved to the osteocytes and squanders to be expelled from them
- Hence, the right answer is "flat bones consist of spongy bone sandwiched between compact bone is true statement"
Answer:
The correct answer is: Type 1 Pneumocytes, and Type 2 Pneumocytes.
Explanation:
The alveoli are structures that form a hollow cavity and are found in the lungs. Alveoli have the very important task of gas exchange, in which deoxygenated blood becomes oxygenated blood to be distributed to every organ in the body.
Alveoli walls are composed of two types of cells:
- Type 1 Pneumocytes have the function of gas exchange between the capillaries, and for that reason, they are very thin and permeable.
- Type 2 Pneumocytes have the function to produce surfactant, a substance very important to maintain the elastic recoil of the lungs. Without surfactant, the lungs would collapse.
