A, B, C, E
Explanation:
A. not fully submerging the object when doing the fluid displacement procedure.
B. water that is left behind in the collection container when it is transferred for measurement.
C. water that soaks into the materials of the balls, affecting the mass in repeated trials.
E. water in the bucket, approximated to the closest 10 mL due to surface tension at the top of the bucket.
Indigenous peoples are important in environmental considerations because:
a. their homelands contain natural habitats least disturbed by humans.
b. their homelands contain a huge proportion of earth's biodiversity.
c. their languages represent encoded knowledge of nature that is irreplaceable.
d. all of the above are correct.
D. seems to be the best answer.
The backbone of DNA and RNA is composed of sugar and phosphate.
DNA is double stranded due to interactions between adenine, cytosine, guanine, and thymine, which are nitrogenous bases.
Uracil is a nitrogenous base that is only used with RNA.
Answer:
B. Granulocyte
Explanation:
Granulocyte is the type of white blood cell with fragments in its cytoplasm. These fragments usually help in the digesting the cells of the foreign body(pathogenic organisms).
There are three main types of Granulocytes which are known as the Neutrophils, eosinophils, and basophils. They all perform variety of functions ranging from phagocytosis to cell lysis of foreign bodies.
Answer:
choanoflagellates and sponges are sister groups
Explanation:
The choanoflagellates are small unicellular organisms belonging to the Protista kingdom. These microorganisms are collared flagellates morphologically similar to the choanocyte cells of animal sponges, which have a central flagellum surrounded by a collar of microvilli. In consequence, it has been suggested that choanoflagellates may represent the closest living relatives of primitive metazoans (i.e., they are sister groups to sponges). This hypothesis has recently been supported by both molecular phylogenetic and comparative genomic analyses.
