The difference between an amniotic egg and eggs laid by other animals is : Absence of Membrane ( amnion ) and absence of larval stage
Characteristics of an amniotic eggEggs laid by amniotes are different from other eggs laid by fishes, amphibians and invertebrates in that they lack a membrane and a larval stage. the shell of the amniotic egg protects the embryo in the absence of a membrane. The shell also allows for the exchange of oxygen and carbon dioxide between the the embryo and the environment.
Hence we can conclude that The difference between an amniotic egg and eggs laid by other animals is : Absence of Membrane ( amnion ) and absence of larval stage

Relying on the knowledge that you have gained from the lessons, explain what types of waste we must remove from our bodies. Why is waste removal required for all organisms?
Answer: Excretion is the removal from the body of waste products which result from normal life processes. Waste products such as carbon dioxide must be removed. If they are allowed to accumulate they cause poisoning which slows down vital chemical reactions.

What part of the visible spectrum is absorbed by the primary pigments of eukaryotic photosynthesis
Chlorophyll a absorbs wavelengths from either end of the visible spectrum (blue and red), but not from green. Because green is reflected, chlorophyll appears green. Other pigment types include chlorophyll band the carotenoids.
What do Primary pigments absorb?There are three primary pigments. Each pigment is designed to absorb a single primary color of light. Cyan pigments absorb red light and reflect blue and green light. Magenta pigments absorb green light and reflect red and blue light.

Osmosis, simple diffusion, and
facilitated diffusion are all examples
of.....
A. passive transport
B. active transport
C. energy assisted transport
Answer:
A
Explanation:
It's passive transport because it does not require energy, i.e. you don't need to invest ATP to make it happen. Osmosis is the movement of water from area of higher solute concentration to area of lower solute concentration. It happens via channel proteins called aquaporines. Simple diffusion is when gases like O2 or CO2 difuse through the cell membrane. Again, they go from area of higher concentration to area of lower concentration. Facilitated difusion is how large and polar molecules go in and out of the cell. This happens via transmembrane proteins down the concentration gradient (from higher to lower concentration).

a. kinetic energy gradient

a cheetah travels 20km west in an hour. The cheetah stops for another hour. Then the cheetah travels another 40km in two hours. What is the velocity of the cheetah
Answer:
The velocity of the cheetah is 15km per hour
Explanation:
First, you add the kilometers that the cheetah travels. Then you should get 60km. Then you put the distance the cheetah travels in a ratio to the hours it took for it to reach its point.
60:4
After that you simplify the ratio which should end up with the final ratio being:
15:1
✅The ratio means 15km each hour which is a rate that can be used in velocity. You can convert it further if you needed it to but I hope it helped you!

Explain how the shape and stacking of the thylakoids contributes to the rate of carbon fixation by the chloroplast.
Chloroplast is the cell organelle that is associated with photosynthesis as it has chlorophyll. When stacked, each thylakoid increases its total surface area, allowing for more electron transport chains to be embedded in each thylakoid membrane.
What is thylakoid?Inside chloroplasts, thylakoids are membrane-bound compartments which are the site of photosynthesis's light-dependent reactions.
Thylakoids are made up of a thylakoid membrane that surrounds a thylakoid lumen. Its main function is to allow the light reactions of photosynthesis.
When the thylakoids are stacked, each of them is able to increase their total surface area which leads to more electron transport chains being embedded into each thylakoid membrane.
Thus, it can be concluded that the shape and stacking of the thylakoids contributes to the rate of carbon fixation by the chloroplast by allowing more electron transport chain.

What effect might obesity have on blood pressure? Does obesity alone cause a person to be at risk for high blood pressure? What other factors, in combination with obesity, might increase a person’s risk for high blood pressure?
Answer:
obesity increases blood pressure
Explanation:
This is because the high fat percentage in the body has lead to a build up of fat on the inside of arteries and this makes them thinner. the heart has to pump harder to get the blood around the body and through these, now smaller arteries. therefore yes having diabetes does increase blood pressure.
other factors which increase blood pressure are high stress levels, smoking, anxiety.

Blood pressure decreases with distance from the left ventricle of the heart
Blood pressure decreases with the distance from left ventricle of heart as the decrease in the diastolic pressure is greater than increase in systolic pressure.
What is diastolic pressure?Diastolic pressure is the pressure exerted in the arteries as the heart rest between the beats.
The decrease in a diastolic pressure is greater than the increase in systolic pressure. This results in an increase of the pulse pressure gradually.
As a result of this, arterial blood pressure decreases in the systemic arteries as the distance from the heart increases.
Thus, blood pressure decreases with distance from the left ventricle of the heart.
