Your three blood cell types have different sizes, shapes, and functions. Yet they all started out alike. Within each cell of your body there are ___________, which give the instructions for cell processes. These instructions include the differentiation of your blood cells. A) centromeres B) chromosomes C) karyotypes D) mitochondria

Answers

Three blood cell types have different sizes, shapes, and functions. Yet they all started out alike. Within each cell of your body there are chromosomes which give the instructions for cell processes.

What is chromosomes?

The thread-like chromosomes that convey the genomic information from cell to cell are formed of protein and a single DNA molecule. Chromosomes are found in the nucleus of cells in both plants and animals, including humans.

There are 46 chromosomes in all, including 22 pairs of numbered chromosomes (autosomes) and one pair of sex chromosomes (XX or XY). Children receive half of their chromosomes from their mother and half from their father because each pair comprises two chromosomes, one from each parent.

The dissolution of the nucleus during cell division allows for the visualization of chromosomes under a microscope. All animals and plants, including humans, have linear chromosomes.

Therefore, Three blood cell types have different sizes, shapes, and functions. Yet they all started out alike. Within each cell of your body there are chromosomes which give the instructions for cell processes.

a. cement mixer
b. bulldozer
c. ditch digger
d. auger

Answers

The effects of Erosion by a Continental glacier can be compared to the actions of a "ditch digger" although it should be noted that there are of course major differences.

Answer:

Bulldozer

Explanation:

Continental glaciers smooth and round expose rock surfaces in a way similar to the way a bulldozer flatten landscapes . pg 461 earth science

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:

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.

How does an increase in cell volume impact the diffusion of materials through the cytoplasm? A. The larger the cell, the longer time it takes for materials to travel.
B. The size of the cell does not impact the movement of materials.
C. The larger the cell, the less time it takes for materials to travel.
D. A larger cell does not require as many materials, so the need for diffusion decreases.

Answers

Answer A is correct. Cells are limited in size because the larger the cell is, the longer it takes for materials to diffuse throughout.

Actions that are reactions to a stimulus are called _____________________.

Answers

The answer is reflex actions.

A reflex action is an involuntary and rapid reaction to a stimulus. So, when a receptor detects a stimulus, the information is sent to relay neuron through a sensory neurone. Relay neuron sends information to the effector through a motor neurone and effector produces a response.
