a
Explanation:
it would be a silkworm because they feed exclusively on animal fibers such as wool. hope this helps!
What would the molecular formula be for the following? For each answer, state what kind of bonds hold the molecule together (ionic, polar-covalent, or non-polar covalent)
a. Flourine reacting with sodium
b. Oxygen reacting with carbon
c. Nitrogen reacting with hydrogen
d. Silicon reacting with hydrogen
e. Sulfur reacting with hydrogen
f. Magnesium reacting with oxygen
Answer:
Explanation:
A. sodium fluoride = NaF = ionic bond
B. carbon dioxide = CO2 = polar covalent bond
C. hydrogen nitrate = 2NH3 = ionic bond
D. silicon hydride = Si nH 2n+2 = polar covalent bond (i think.. could be non-polar but definitely not ionic)
E. hydrogen sulfide = H2S = non-polar covalent bond
F. magnesium oxide = MgO = ionic bond
hope this helps! :)
Example on one of the 3 laws of motion
Answer:
Newton's First Law of Motion
Explanation:
A body at rest persists in its state of rest, and the body in motion remains in uniform motion along a straight line unless acted upon by a net external force.
A Class-A 10 mL pipette is supposed to dispense 10.00 mL of water. A lab technician makes three measurements of the volume that the pipette actually dispenses, and obtains volumes of 9.70 mL, 9.69 mL, and 9.71 mL. The pipette is:__________
a) Accurate, but not precise
b) Precise, but not accurate
c) Accurate and precise
d) Neither accurate or precise
Answer:
d) Neither accurate or precise
Explanation:
Accuracy and precision are critical factors in the experimental procedure. Accuracy can be defined as the amount of uncertainty in the process of measurement in relation to the true value (in this case, 10 mL). On the other hand, precision is an independent feature of the accuracy which indicates the repeatability of the measurement process (in this case, three measures weren't repeated). Therefore, precision indicates the confidence of a particular measurement, while accuracy indicates how close is this value to the real value.

3.4 Briefly describe the purpose of conjugation in paramecia.
Answer:
Conjugation is a process of exchange of genetic material between two organisms. paramecium is a unicellular protozoan in which true sexual reproduction is absent. so in these organisms conjugation brings genetic variatin in new generations.
Explanation:
The function of conjugation in paramecium is to exchange genetic material between organisms and make new combinations of genetic material.

Describe how the gonorrhoea pathogen causes disease after it enter the body
Answer:
Gonorrhea is transmitted through sexual contact with the penis, vagina, mouth, or anus of an infected partner. Ejaculation does not have to occur for gonorrhea to be transmitted or acquired. Gonorrhea can also be spread perinatally from mother to baby during childbirth.
What causes the earths tides; describe the conditions for the largest tides?
Answer:
Earth's rotation and the gravitational pull of the sun and moon create tides on our planet. Because the sun is so much larger than the moon (27 million times more masssive), it has a much bigger graviational pull on Earth.
Place the following events in
the cell cycle in the proper
order:
a. Anaphase
b. Cytokinesis
C. G2
d. Telophase
e. G1
f. Prophase
8. S
h. Metaphase
The cell cycle in the correct order is G1, S, G2, Prophase, Metaphase, Anaphase, Telophase, and Cytokinesis.
What is the cell cycle?Prophase, metaphase, anaphase, and telophase are the four phases that a cell goes through. To form chromosomes, chromatin condenses (sister chromatids joined at the centromere).
In prophase, the chromosomes get shorter and thicker, in the center of the cell, during the metaphase, the chromosomes align. Chromatids separate during the anaphase process and travel to the opposing poles.
Telophase: Two nuclei are produced when nuclear envelopes have reformed around each chromosomal group.
Therefore, the cell spends the majority of its time in interphase, which is also when it grows, duplicates its chromosomes, and gets ready to divide.
