Answer:

These gel cubes can be thought of as representing individual cells. As the cubes interact with their surroundings based on the amount of surface area and volume they have, the efficiency movement of substances in and out of cells depends on the two attributes as well. Greater surface area will mean more efficient rates of diffusion, which implies a smaller surface area to volume ratio is ideal for a biological cell.

Hope that answers the question, have a great day!

Paul [167]

Answer:

GL, Gl, gL, and gl

Explanation:

The mom is glossy long haired. Since glossy (G) is dominant over to dull (g) and long hair (L) is dominant to short hair (l), the possible genotypes of the mom would be:

GGLL, GgLL, GGLl, or GgLl

The dad is dull and short haired, the genotype would be ggll.

GGLL x ggll

Progeny = all GgLl (all glossy long haired)

GgLL x ggll

Progeny = 8 GgLl, 8 ggLi (glossy long haired and dull long haired)

GGLl x ggll

Progeny = 8 GgLl, 8 Ggll (glossy long haired and glossy short haired)

GgLl x ggll

Progeny = 4 GgLl, 4 Ggll, 4 ggLl, 4 ggll (glossy long, glossy short, dull long, and dull short)

Only a cross of ggll with GgLl produced the offspring that cover the phenotypic range shown in the illustration. Hence, the genotype of the mom is GgLl.

The parental gametes produced by the mom would be; GL, Gl, gL, and gl

The graph represents velocity vs. time for Carla. A graph with horizontal axis time (seconds) and vertical axis velocity (meters

kherson [118]

Answer:

The statement that best describes the graph is Carla slowed down in the beginning of her trip, stopped, and then sped up.

Explanation:

Data:

Horizontal axis = time.

Vertical axis = velocity (m/s).

A line runs in straight segments

from 0 seconds 15 m/s.
to 1 seconds 13 m/s.
to 2 seconds 10 m/s.
to 3 seconds 4 m/s.
to 4 seconds 0 m/s.
to 6 seconds 4 m/s.

According to the data present in the graph, it can be seen that Carla starts with a speed in her career, which decreases over time. After four seconds she stops, remains stopped for one second and starts running again, with an initial speed of 4 m/s.

In conclusion, the graph show Carla -who is moving- slows down until she stops, and then starts the race again.

When two objects are near each other, how would increasing one object's mass affect it

Bumek [7]

Answer:

When two objects are near each other, increasing one object's mass would cause the gravitational force of the object to increase. where m and M are the masses of the two objects, d is the distance between their centres, and G is the gravitational constant.

Explanation:

one is big one is small

In certain kinds of muscle cells, calcium ions are stored in ________. The rough er both smooth and rough er the cytoplasm the s

Nadusha1986 [10]

Answer;

-In the smooth ER

In certain kinds of muscle cells, calcium ions are stored in the smooth ER.

Explanation;

-The smooth endoplasmic reticulum is the part of the endoplasmic reticulum (ER) which does not have ribosomes bound to it, thus not exhibiting the bumpy appearance shown by the rough endoplasmic reticulum.

-The smooth ER is important in the synthesis of lipids, such as cholesterol and phospholipids, which form all the membranes of the organism. In addition it is important for the synthesis and secretion of steroid hormones from cholesterol and other lipid precursors.
