Why do heart cells have different characteristics than skin cells???
Heart cells have different DNA than skin cells.
Heart cells reproduce by mitosis.
Heart cells express different genes than skin cells.
Heart cells reproduce by cell differentiation.
Answer:
Heart cells express different genes than skin cells
Explanation:
Cells contain instructions for their gene expression within stretches of DNA called genes, which is expressed and translated into protein.
Somatic cells are cells which contain the organism's chromosome number. They contain the entire karotype- and divide/ replicate through mitosis. In several stages of mitosis, DNA becomes condensed, is unwound and replicated, then packaged into two identical daughter cells.
All somatic cells start out undifferentiated (as stem cells). AFter the process of differentiation, they undergo changes in gene expression to become specific cell types, through processes like methylation and gain maturity.

Let's look at the original hypotheses arising from the original question: "Does the size of the
substance affect its ability to diffuse across cell membranes?"
Small substances: If the size of a substance is important in its ability to
diffuse across a cell membrane, then small substances should be able to
freely diffuse across cell membranes.
?
Large substances: If the size of a substance is important in its ability to
diffuse across a cell membrane, then large substances should not be able
to freely diffuse across cell membranes.
?
Do the observations of H+?glucose and cortisol support the
hypotheses?
Explain your answer
Answer:
H1: false, the observations of the molecules do not support the hypothesis...
Explanation:
The cell membrane is comprised of a phospholipid bilayer, proteins, and cholesterol. These components help the membrane to maintain its selective permeability and concentration of solutes and water.
The lipid molecules have polar hydrophilic heads and hydrophobic tails. These only readily allow for the movement of small non polar molecules. Other substances, like charged ions and large molecules require transport proteins to move in and out of the cell. Hypothesis: H+ is small and should be able to move freely through the membrane, While glucose is large and cannot move freely
Observing H+, despite being very small these cannot easily pass through the membrane. They require transport proteins called channels for their free movement or passive movement across the membrane.For glucose, these molecules pass through specialized channels in facilitated diffusion. They move down their concentration gradient into the cell. To move out of the cell against its concentration gradient glucose requires ATP for active transport.Cortisol, is a large steroid hormone, taken into the cell by simple diffusion across the lipid membrane, down its concentration gradient.This cell membrane component identifies the cell and is only found on the outside of the membrane.

For each molecule of glucose, glycolysis only makes 2 ATP, the Krebs cycle only makes 2 ATP and the ETC makes 34 ATP. If the suspects had given Jared the 2-deoxyglucose poison, would the decrease in ATP concentration be smaller, the same or larger as when they used cyanide? Explain your answer.
(This is from the cellular respiration gizmos lab)
Answer:
Decrease in ATP concentration be larger.
Explanation:
Decrease in ATP concentration be larger because 2-deoxyglucose poison inhibit glycolysis. Glycolysis is the first step of energy production where glucose break down started. If the first step of ATP production is stopped, no energy will be produced so we can conclude that 2-deoxyglucose poison causes decrease in ATP concentration be larger.
The decrease in ATP concentration would be larger when 2-deoxyglucose
poison is given alongside cyanide.
This is because 2- deoxyglucose will inhibit the production of ATP in the
cells of the body. This lead to decreased or no ATP being generated. The
presence of cyanide will also lead to a decrease in the concentration due to
presence of other compounds.
This subsequently leads to a decrease in the concentration of the ATP
present in the solution. This also enables us to deduce that the decrease in
the ATP concentration would be larger.

Explain how the daily energy needs are different between the zebra and its predator, the lion. Be certain to include any pertinent differences in the digestibility of these organisms’ food sources, along with differences in digestive tracts and energy spent on digesting. Cite any behaviors you feel may play a role as well.
Answer:
Both animals eats different types of food so they have different digestive system.
Explanation:
The daily energy needs are different between the zebra and its predator, the lion because they have difference in daily activities and they eat different types of food and. Zebra is herbivorous animal while the lion is carnivorous so there is highly difference occurs in their digestive system. Zebra activities is to eat plants and run from the prey which needs more calories but the lion needs very high amount of calories for catching their pray for food.

do scientists consider earth an essentially open or closed system? why
If it is __________ in the Northern Hemisphere, then it must be __________ in the Southern Hemisphere. A. summer . . . Summer B. spring . . . Winter C. winter . . . Winter D. winter . . . Summe
Answer:
The correct answer is D. winter ... summer
If it is WINTER in the Northern Hemisphere, then it must be SUMMER in the Southern
Explanation:
There are different cycle processes on earth. One of them is the season cycle. Seasons are the result of the Earth´s movement of translation and the inclination of the Earth´s axis with respect to the plane of the orbit. The solar radiation reaches perpendicularilly the surface in different regions of the earth, during an annual cycle. This differential heatting produces the seasons. When it is winter in the northern hemisphere, it is summer in the southern hemisphere. When it is autumn in the northern hemisphere, it is spring in the southern hemisphere. And the exact opposite this occurs. Also, due to the shape of the orbit, summers are warmer in the southern hemisphere.
So, imagine the Earth as a circle. Now imagine that this circle is crossed by a longitudinal line (the earth axis). This axis points to the north pole and to the south pole. Now imagine that this axis is not exactly vertical, but it is inclined.
This circle (the earth) is in an orbit, which has an ovoid shape. This ovoid shape has two extremes, let us call them extreme A and B. Inside the orbit, there is the sun. But the sun is not in the middle. Instead, it is nearer to one of the arbit extremes, let us say it is closer to the B extreme.
During translation, the earth moves along the orbit receiving the sun´s radiation. When the earth is in the B extreme, it is closer to the sun and receives higher radiation. And due to the earth´s inclination, the southern hemisphere is getting much more radiation than the northern hemisphere. At this point, there is summer in the southern hemisphere and winter in the northern hemisphere. But when the earth is in the extreme A of the orbit, the north is getting more direct radiation from the sun. In this extreme, it is summer in the northern hemisphere and winter in the southern hemisphere.
Answer:
If it is winter in the Northern Hemisphere, then it must be Summer in the Southern Hemisphere.
In a prairie ecosystem, which of the following populations has the most stored energy for use by other organisms?
A prairie grasses
B. prairie dogs
C. coyote
D. hawks
Answer:
I believe the answer would be A. because grass stores the energy it gets from the sun. Therefore it'd have more stored energy for other organisms to use.
Explanation:
In prairie ecosystem, the population with the most amount of stored energy for use by other organisms would be the prairie grasses.
Prairie ecosystems are ecosystems formed from continuous interactions between some biotic and abiotic factors such as plants, animals, fire, temperature, landforms, and precipitation. These interactions lead to the ecosystem being dominated by grasses and forbs as well as animals such as prairie dogs, squirrels, pronghorn, coyotes, and many more.
Prairies grasses are the primary producers in prairie ecosystems. They fix energy directly from the sun through the process of photosynthesis.
Thus, prairie grasses, and generally, producers in any ecosystem, hold the highest amount of energy that can be used by other organisms in the food chain or web of an ecosystem.
Other organisms such as the prairie dogs, coyote, and hawks are consumers.
