The above picture represents the different stages a cell goes through in its "lifetime." Specific genes within the DNA, called inhibitors, stop the cell cycle in G1 phase.

HELP ASAP!!!If you are younger than your best friend but older than another friend, do you know your absolute ages, relative ages, or both?

Answers

You do not know absolute ages. For that you would need to know specific numbers. However, you do know the relative ages of all three.

Use the models that you created in Lesson 2, Lab 1 to help you answer the following question. Compare the surface area to volume ratio of a large cell to that of a small cell.

Why does the ratio of surface area to volume increase with the decrease in cell size?


A. A larger cell has more surface area than volume.
B. A smaller cell has more surface area than volume.
C. A smaller cell has more volume than surface area.
D. A smaller cell has an equal ratio of surface area to volume

Answers

Answer:

B

Explanation:

This is a question more about understanding ratios than understanding cells.

A surface area to volume ratio (S/V) in a size-decreasing cell would increase due to a more significant loss in volume that in surface area. In reality, both decrease (surface area AND volume), but as we are talking about a ratio, this one would go up due to a more dramatic decrease in volume.
B. A smaller cell has more surface area than volume. This allows for more reactions to occur across the various membranes of the cell.

As set of overlapping DNA fragments that form a contiguous stretch of DNA is called aA) chromosome.
B) sequence.
C) map.
D) contig.

Answers

the answer is D) contig

Acontiguous stretch of DNA formed from overlapping DNA fragments is known as a contig. Contigs are a crucial component in DNA sequencing and genome assembly.

A set of overlapping DNA fragments that form a contiguous stretch of DNA is referred to as a contig. In molecular biology and genetics, contigs are used in the process of DNA sequencing to assemble larger sequences of DNA from smaller sequences or fragments. Creating a contig is a crucial step in genome assembly, and it is typically accomplished using computer algorithms that match overlapping ends of different DNA fragments.

Which of the following is true about soil color? a. A dark color indicates that the soil is poor in organic matter. b. Bright yellow and red colors indicate large amounts of organic matter. c. Yellow or red hues in the soil indicate the presence of iron or aluminum. d. Yellow or red hues in the soil indicate the presence of calcium or magnesium.

Answers

Answer: c. Yellow or red hues in the soil indicate the presence of iron or aluminum.

Soil color is a property of soil, it depends on various factors like the amount of organic matter present in the soil, type of minerals and porosity of soil (amount of pores present in the soil). Usually, dark soils have comparatively higher organic matter content than light colored soils.

Yellow or red hues in the soil indicates the presence of iron or aluminum it is the true statement about soil color. It depicts the fact that the color of soil is because of presence of particular mineral in it. Yellow or red color of the soil is an indicative of iron in the oxidized form as ferric iron oxides.


The only one correct answer would be:

c. Yellow or red hues in the soil indicate the presence of iron or aluminum.
