Answer:
Option C. Long Legs.
Explanation:
Anti-predator adaptations are mechanisms developed through evolution that assist prey organisms in their constant struggle against predators. If prey becomes more scarce, the variation which provides and advantage to the prey is the possession of of long legs. The long legs possessed by the prey will allow the prey to take huge strides when running away from the predator.
It would be C because the ozone layer blocks out harmful radiation from reaching the surface of earth. Hope this helps! - cat
Incomplete question. The full question read;
6. Which isn’t a word that shows the outlet isn’t completely sure about a particular statement?
Answer:
<u>certainly</u>
Explanation:
Of course, media outlets would not use the word<em> "certainly" </em>to refer to a particular statement they are not sure of because the word is used connotatively when what is been said is believed to be true.
Hence, other words such as "possibly", "likely" are used when they are not completely sure about a statement.
Answer:
Here are the answers:
a. 4 Cell determination as an issue in the *rest is missing*
b. 4 They assumed that different ways of separating an embryo into two parts would be equivalent as far as the fate of the two parts was concerned.
c. 4 I and III only
Explanation:
The passage demonstrates the importance of two factors in the development of an embryo: cleavage planes of division of embryonic cells and cell differentiation.
Cleavage Planes:
Cleavage basically refers to the division of the zygote into a large number of cells called blastomeres. Cleavage planes are geometrical lines or orientations along which cleavage takes place. Since, all embryonic cells are the precursors of some type of body cells, the cleavage planes determine if the cells are adequate for growth and development.
Cell Differentiation:
Cell differentiation is the transition of an undifferentiated cell into a specialized one. For example, stem cells are undifferentiated cells that develop into progenitor cells that mature into a specific cell lineage. For an embryo to regenerate, the presence of adequate embryonic stem cells is crucial. Embryonic stem cells are present in abundance before the gastrulation phase of embryonic development, after which they rapidly start differentiating.
Answer:
I know the first and second picture is wrong, not sure what the right one is. Hope this helps some
