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.
This molecule is a product of photosynthesis and is a major source of energy for plants and animals. This molecule is converted to ATP by the mitochondria.
Answer:
This question is asking to identify the molecule being described.
The molecule is GLUCOSE
Explanation:
Photosynthesis is the process by which green plants make their food using energy from sunlight. This food, which happens to be the product of the photosynthetic process is GLUCOSE molecule. Glucose is the source of energy during cellular respiration for plants and animals as it is broken down to synthesize ATP.
The process of cellular respiration, which is carried out by virtually all living organisms make use of the GLUCOSE MOLECULE. The energy stored in the glucose molecule is converted to ATP in the mitochondria.
How are influenza viruses classified?
by their type of movement
by their protein structure
by their genetic material
by their different shapes
Answer: They are classified by subtypes based on the properties of their hemagglutinin (H) and neuraminidase (N) surface proteins. There are 18 different HA subtypes and 11 different NA subtypes. Subtypes are named by combining the H and N numbers.
1.There movement: People with flu can spread it to others up to about 6 feet away. Most experts think that flu viruses spread mainly by droplets made when people with flu cough, sneeze or talk. These droplets can land in the mouths or noses of people who are nearby or possibly be inhaled into the lungs.
2. There protein structure: The influenza viruses are classified into types A, B, and C on the basis of their core proteins. Type A viruses are further subdivided according to their envelope glycoproteins with haemagglutinin (HA) or neuraminidase (NA) activity.
3. There genetic material: by subtypes based on the properties of their hemagglutinin (H) and neuraminidase (N) surface proteins. There are 18 different HA subtypes and 11 different NA subtypes. Subtypes are named by combining the H and N numbers – e.g., A(H1N1), A(H3N2)
4. Different shapes: I don't know that one
Explanation: Hope this helps though :)
Answer:
b) by their protein structure.

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.

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.

Why is palliative care important?
to destroy the microbes causing infectious disease
to cure the patient from an infectious disease
to relieve the symptoms of an infectious disease
to prevent the contraction of an infectious disease
Answer:
To relieve the symptoms of an infectious disease
Explanation:
The purpose of palliative care is to relieve the symptoms of a disease. It's applied to people who live with a serious, often incurable illness. Its goal is to improve the quality of life for both the patient and their family.
As this type of treatment is for people who are already ill and cannot be cured, the rest of the options are incorrect.
A liquid and a solid mixed together. What does NOT indicate that a
chemical change has taken place?
Explain what would happen if conditions changed that causes the seaweed to die now striped fish stand out to predators more than solid fish how could natural selection result in the change to relative numbers of solid and striped fish?
Answer:
An organism change itself in response to the surrounding environmental condition.
Explanation:
Since striped fishes are able to save themselves from the predators due to their natural ability , the solid fishes would be an easy prey to the predators. This would lead to reduction in the number of solid fishes. Also the sea weed started dying because of environmental change. Thus, predators would shift their feeding pattern from sea weed to easily identifiable fish that is the solid fish and hence the solid fish may deplete rapidly.
Also the striped fishes in later stages may undergo natural selection to prevent themselves from the predators.

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.
