Outline the four stages of the demographic transition as it occurred in Europe and North America.
Answer:
Stage 1—High birth and death rates lead to slow population growth.
Stage 2—The death rate falls but the birth rate remains high, leading to faster population growth.
Stage 3—The birth rate starts to fall, so population growth starts to slow.
Stage 4—The birth rate reaches the same low level as the death rate, so population growth slows to zero.

which of the following is not an abiotic factor in the prairie ecosystem a water b sunlight c grass d soil
Answer:
Grass
Explanation:
Biotic means living. There are some obvious abiotic factors here. The only gray area is what "soil" encompasses
grass-Biotic means living, all of the other choices are not living, and would therefore be abiotic factors
This is because it is a living thing (performs photosynthesis and cellular respiration).

How is the electromagnetic spectrum organized from right to left?
Answer:
Electromagnetic waves exist with an enormous range of frequencies. This continuous range of frequencies is known as the electromagnetic spectrum.
Explanation:
The longer wavelength, lower frequency regions are located on the far left of the spectrum and the shorter wavelength, higher frequency regions are on the far right.
Which of these options is not a mechanism to control the opening and closing of ion
channels?
a) ATP binding (ATP gated)
b) Ligand binding (ligand gated)
c) Changes in membrane potential (voltage gated)
d) Distortion of the cell membrane (mechanically gated)
Answer:
D) ATP binding (ATP gated)Explanation:
There are three types of ion gated channel regulated by ligand binding, change in membrane potential and distortion of the cell membrane...
So the answer is ATP Binding( ATP gated) is not a mechanism to control opening and closing of Ion channels.
ATP binding (ATP gated) IS NOT a mechanism to control the opening and closing of ion channels (Option a).
ATP-gated channels are membrane channel proteins that open in response to binding ATP.
These channels require energy in the form of ATP to open and thus allow the passage of ions/molecules across biological membranes.
For example, the P2X7 receptor is an ATP-gated channel that mediates apoptosis (programmed cell death) of immune cells.
In conclusion, ATP binding (ATP gated) IS NOT a mechanism to control the opening and closing of ion channels (Option a).

The normal body temperature of an adult human is between 36.1°C and 37.2°C. The normal body temperature of an adult chicken is between 40.6°C and 41.7°C. Based on this information, do you think most human enzymes and chicken enzymes have identical structures? Explain why or why not.
Answer:
Almost 60% of chicken genes correspond to a similar human gene. Although, researchers uncovered more small sequence differences between corresponding pairs of chicken and human genes, which are 75% identical on average, than between rodent and human gene pairs, which are 88% identical on average

A scientist looks at lung tissue under a microscope. Which level of
organization is simpler than lung tissue?
A. The respiratory system
B. The organism
C. Lung organ
D. Lung cells
Answer:
D. Lung cells
Explanation:
There are many organizations of living things and parts of living things. From simplest to complex the levels are: cells, tissue, organ, system, organism. So, if you have lung tissue then the only simpler organization is cells. These are simpler because cells are what make up tissue, just as tissue makes up organs. Through the levels, the more simple something is then the smaller it is, relatively.

how many copies of each chromosome are contained in each of the daughter cells resulting from meiosis?
Answer:
Each daughter cell will have half of the original 46 chromosomes, or 23 chromosomes. Each chromosome consists of 2 sister chromatids. The daughter cells now move in to the third and final phase of meiosis: meiosis II. At the end of meiosis I there are two haploid cells.
Explanation:
Hope this helps.
Each daughter cell has 23 of the 46 chromosomes. Sister chromatids make up each chromosome. Daughter cells enter meiosis II, the final step. Two haploid cells result from meiosis I.
What is meiosis?Meiosis is a specialized kind of cell division that occurs in the germ cells of animals that reproduce sexually. This form of cell division is responsible for the production of gametes, such as sperm and egg cells. This process requires two rounds of cell division, and at the end of it, there are four cells that each have a single copy of each chromosome.
There are 46 chromosomes total, and each daughter cell has 23 of them. Each chromosome is composed of two sister chromatids. In the second and last stage of meiosis, daughter cells participate. Meiosis I always results in the formation of two haploid cells.
