Which set of atoms can be found in ALL carbon-based molecule?
Answer:
All organisms are made of four types of carbon-based molecules: carbohydrates, lipids, proteins, and nucleic acids. These molecules have different structures and functions, but all are formed around carbon chains and rings.
Carbon-based molecules have three fundamental structures—straight chains, branched chains, and rings.

What would be the correct complimentary DNA strand given the following DNA strand.
DNA: ATACGAAAT (Type as one word - no spaces)
Using the same strand of DNA, what would be the correct sequence for an RNA strand? (Type as one word - no spaces)
Answer:
TATGCTTTA for question 1.
For RNA following the original strand it would be UAUGCUUUA
Explanation:
Replace A with T(vice versa), and C with G(vice versa)
But for the RNA, A bonds with U instead of T. So it would be the same as the complimentary DNA, just with U instead of T
In the laboratory, yeast cells are usually grown at a temperature of 25oC. A scientist wanted to determine if yeast cells would reproduce faster or slower when the temperature was dropped to 15oC. The same number of yeast cells were placed in the same medium with the same amount of nutrients. One sample was kept at 25oC and the other one was kept at 15oC. The number of yeast cells was counted every hour for an eighteen hour period.
Answer:
This question is incomplete, however, it is asking to identify the following variables:
Independent variable: Temperature
Dependent variable: Number of yeast cells
Constants: same amount of nutrients, same number of yeast cells, same medium
Explanation:
- Independent variable is the variable that the experimenter changes or manipulates in order to bring about a measurable effect. In this experiment, the TEMPERATURE at which the yeast are kept is the independent variable.
- Dependent variable is the variable that responds to the changes made to the independent variable. It is the variable that is measured by the experimenter in the experiment. In this case, The NUMBER OF YEAST CELLS was counted, hence, it is the dependent variable.
- Constants are variables that are kept unchanged or same for all groups by the experimenter in order not to influence the experiment's outcome. In this case, the CONSTANTS are: same amount of nutrients, same number of yeast cells, same medium etc.
In silkworms,yellow cocoon (B) is dominat over white cocoon(b). If the mom is BB and the dad is bb, what are the chances they have offspring with yellow cocoons?
Answer:
100 %
Explanation:
Dominance is a genetic phenomenon where a gene variant or allele masks the effects of another allele (of the same gene) in heterozygous individuals. This last gene variant is referred to as the recessive allele. In this case, the silkworm mother can produce only one type of gamete carrying the dominant gene (B) form, while the silkworm father can produce only one type of gamete carrying the recessive gene (b) form. In consequence, from this cross, all offspring (100 %) will be heterozygous (Bb) and therefore they will express the dominant trait (i.e., yellow cocoon).

Answer:
it has to be. either remaining exon are spliced together, intron are removed, or remaining intron are spliced together.
Explanation:
i got introns and extrinsic are spliced and exons are removed and got them wrong
Answer:
In the box next to the First mRNa (First Box), it is that the Introns are removed.
In the box next to the Final mRNa (Bottom Box), it is the remaining exons are spliced together

This picture shows a cross-section of a blood vessel. The diameter of the
lumen in Figure 10 is 25.0 mm. What is the actual diameter of the lumen of
this blood vessel?
lumen
magnification X8
3.1 x 10-2m
3.1 x 10-3 m
O 2.0 x 10-2 m
2.0 x 10-3 m
Answer:
B. 3.12 x [tex]10^{-3}[/tex] m
Explanation:
From the given picture, it can be deduced that;
the diameter of the image of lumen = 25.0 mm
= 25.0 ÷ 1000
= 0.025 m
And,
magnification = [tex]\frac{diameter of the image of lumen}{actual diameter of lumen}[/tex]
But magnification = 8,and diameter of the image of lumen = 0.025 m.
So that;
8 = [tex]\frac{0.025}{actual diameter of lumen}[/tex]
⇒ actual diameter of lumen = [tex]\frac{0.025}{8}[/tex]
= 0.003125
Actual diameter of lumen of the blood vessel is 3.12 x [tex]10^{-3}[/tex] m.

What is the role of microfilaments in cell division?
Answer:
to help divide the cell during mitosis/ aid the process of cytokinesis
Explanation:
Answer:
microfilaments are made up of proteins including actin and myosin
these proteins help "pinch off" the two daughter cells during cell division during the final stages, a microfilament ring forms and contracts to separate the new cells during cytokinesis.

SARS-CoV-2 is a respiratory virus. What makes a respiratory virus more difficult to contain than a pathogen that is spread through contaminated food, for example?
Answer:
a respiratory virus is usually air borne. while contaminated food can only harm you if ingested. with SARS, if you breath in contaminated air, its a lot easier to get it.

Explanation:
You are comparing the density of sea water to the density of fresh water. (Remember,
density is mass divided by volume.) Describe how you could determine the density of
sea water, including the names of the equipment needed to make the required
measurements.
Answer:
To know and compare the difference between the density of the fresh water and salt water or sea water require a graduated cylinder, balance, and weighing machine. The graduated cylinders are the containers that have markings on them to measure the volume of the liquid.
First, fill the cylinder with 1000 ml of fresh water which is the measure of the volume. now weight the cylinder filled with the fresh water and then find the difference between filled and empty container divide the mass of the fresh water by its volume, the result is the density of fresh water.
Repeat the process with salt water or sea water. The answer would be sea water has more density than fresh water.

The __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ carries low oxygen blood to the lungs and brings high oxygen blood back to the heart.
Answer:
Pulmonary blood vessel
Explanation:
The pulmonary blood vessel carries low oxygen blood to the lungs and brings high oxygen blood back to the heart.
More specifically, the pulmonary artery carries low-oxygen blood to the lung from the right ventricle of the heart. The blood becomes oxygenated in the lung and the oxygen-rich blood is taken back to the left atrium of the heart by the pulmonary vein.
