Trilobites Are Extinct Marine Invertebrates. Scientists Found A Trilobite Fossil Inlayer 5, Shown Here.

Answers

Answer 1

Fossils in the 4 layer are likely to be slightly older than this trilobite fossil because this layer is present below that 5 layer.

What is fossil?

Fossils are the preserved remains parts or traces of remains of ancient organisms that were extinct long time ago. Fossils are the rocks that can preserve on entire organism such as bones, shells and feathers etc.

So we can conclude that fossils in the 4 layer are likely to be slightly older than this trilobite fossil because this layer is present below that 5 layer.

Erythrocytes (red blood cells)have no nucleus, mitochondria, orother organelles at maturity. Theseorganelles are ejected when the RBCenters the bloodstream, or shortlythereafter. Should this still beconsidered a cell? What will be theeffect of having no nucleus? In thesecells, the lack of mitochondria is anadvantage. Why?

Answers

Answer:

Erythrocytes are not considered true cells, because of their lack of a nucleus. The effect of having no nucleus makes their self-reproduction impossible, and the absence of mitochondria is a disadvantage because they have to obtain energy by alternative reactions.

Explanation:

Erythrocytes, or red blood cells, are the structure in charge of transporting gases in the blood. When these cells are mature, they have already lost their nucleus —in order to have space to house the hemoglobin molecule— which prevents mature red blood cells from being able to reproduce.

Additionally, red blood cells do not have mitochondria —the main energy generator in eukaryotic cells— so in order to obtain energy they need to perform lactic fermentation, with a lower enegetic yield, which may be a disadvantage, but sufficient for this structure to perform its function.

1. How much force accelerate a bicycle and rider with mass 60 kg at 1.5 m/s?

Answers

Answer:

Force, F = 90 N

Explanation:

Given that,

Mass of the bicycle and rider, m = 60 kg

Acceleration of the bicycle and rider, a = 1.5 m/s²

We need to find the force acting on the bicycle and rider to accelerate. Let it is F. Its force is given by :

F = ma

F = 60 kg × 1.5 m/s²

F = 90 N

So, the force acting on the bicycle and rider is 90 N.

A cell’s nucleus will divide during mitosis. Whaat process must happened before it can divide?

Answers

Prokaryotic cells, which include bacteria, undergo a type of cell division known as binary fission. This process involves replication of the cell's chromosomes, segregation of the copied DNA, and splitting of the parent cell's cytoplasm. The outcome of binary fission is two new cells that are identical to the original cell.

A scientist is extracting the DNA of a multicellular organism. He finds that 20% of the strands bases are Thymine. Based on Chargaff's rule, what percentage of the
strands bases would be Adenine?

A. 20%
B. 70%
C. 40%
D. 60%

Answers

Answer:

A. 20%

Explanation:

A DNA molecule consists of four nucleotides viz: Adenine (A), Thymine (T), Guanine (G), and Cytosine (C). According to Chargaff in his complementary base pairing rule, these nucleotides pair with one another in such a way that A bonds to T, while G bonds to C.

Based on Chargaff's rule, the amount of Adenine in the DNA is equal to the amount of Thymine while the amount of Guanine is equal to that of Cytosine i.e. A=T, G=C.

A + T + G + C = 100%

Hence, in this question, a scientist finds that 20% of the strands bases are Thymine. This means that the amount of Thymine in that DNA will also be 20%. S

Since A=T = 20% in accordance to Chargaff rule.

Calculate the volume in mL of a stock solution of 100% ethanol, required to prepare 2 L of a 70% solution of ethanol in dH2O

Answers

Answer:

For example, to make 70% ethanol from 95% ethanol, take 70 mL of 95% ethanol and add enough water to bring the volume to 95 mL. You will then have 95 mL of 70% ethanol. This works for any dilution and all that is required is a large enough graduated cylinder.

When using liquid reagents, the percent concentration is based upon volume per volume, i.e. #ml/100ml. Example 2: If one wished to make a 70% ethanol solution, 70 ml of 100% ethanol would be dissolved in 30 ml of water (or the equivalent for whatever volume was needed).
