Answers
Answer:
SKELETAL MUSCELES CARDIAC MUSCLES SMOOTH MUSCLES
Explanation:
SKELETAL MUSCLES -: There are long, cylindrical, and striated skeletal muscle cells. They are multi-nucleated, which means they have more than one nucleus. This is because from the fusion of embryonic myoblasts, they are created. Each nucleus controls the sarcoplasm's metabolic demands around it. There are high energy requirements for skeletal muscle cells, because they contain several mitochondria in order to generate adequate ATP. Examples of skeletal muscles: arms and legs- The muscles that belong to the arms and legs feature in pairs. Abdomen and Back- These muscles are connected to the various sets of skeletal muscles that run across the torso.CARDIAC MUSCLES -: Cardiomyocytes have a short and narrow outline and are fairly rectangular. They are about 0.02 mm wide and 0.1 mm (millimetres) long, respectively. There are many sarcosomes in cardiomyocytes, which provide the required energy for contraction. Cardiomyocytes usually contain a single nucleus, unlike skeletal muscle cells. Cardiomyocytes, although they contain more sarcosomes, normally contain the same cell organelles as skeletal muscle cells. example - cardiac muscle is present in heart. SMOOTH MUSCLES -: Smooth muscle cells have a single central nucleus and are spindle-shaped. They range in length from 10 to 600 μm (micrometers), and are the tiniest type of muscle cell. In the expansion of organs like the kidneys , lungs, and vagina, they are elastic and therefore essential. As in cardiac and skeletal muscle, the myofibrils of smooth muscle cells are not aligned, meaning they are not striated, hence the term smooth. example of smooth muscles -: Walls of blood vessels , Walls of stomach , Ureters , Intestines , In the aorta (tunica media layer), Iris of the eye. ,Prostate and Gastrointestinal Tract.
9. Which class of organic compounds is used by the body for cell repair and growth?
(1) carbohydrates
(3) minerals
(2) proteins
(4) lipids
Answers
Answer:
Proteins
Explanation:
Minerals are not organic compounds, and carbs and lipids do not repair/grow cells (lipids are primarily used to store energy and insulate/protect the body and carbs provide a short boost of energy).
Protein is a nutrient used to make and repair our body cells (like blood and muscle cells). About 1/2 of your dry body weight is protein. If you do not eat enough carbohydrates, protein will be changed to carbohydrates so that you can get energy.
How do ATP and NAPDH connect light-dependent and light-independent reactions in photosynthesis
Answers
ATP and NADPH serve as key molecules that connect the light-dependent and light-independent reactions in photosynthesis. They play crucial roles in transferring energy and reducing power between the two processes, ensuring the overall efficiency of photosynthesis.
1. Light-Dependent Reactions: These reactions occur in the thylakoid membranes of the chloroplasts and convert light energy into chemical energy. During this process, light energy is absorbed by chlorophyll and other pigments, leading to the generation of ATP and NADPH.
2. ATP Generation: The absorbed light energy is used to power the electron transport chain, which pumps protons across the thylakoid membrane, creating a proton gradient. The flow of protons back across the membrane through ATP synthase generates ATP from ADP and inorganic phosphate.
3. NADPH Generation: Simultaneously, the energized electrons from the electron transport chain are transferred to NADP+, reducing it to NADPH. This process requires the input of high-energy electrons and protons.
4. Light-Independent Reactions (Calvin Cycle): ATP and NADPH generated during the light-dependent reactions are utilized in the stroma of the chloroplasts to fuel the Calvin cycle. Here, carbon dioxide is fixed and converted into glucose through a series of enzymatic reactions.
5. ATP Utilization: ATP provides the necessary energy to power the various enzyme-catalyzed reactions in the Calvin cycle. It is used to drive the carboxylation of ribulose bisphosphate (RuBP), the regeneration of RuBP, and other key steps in the cycle.
6. NADPH Utilization: NADPH functions as a reducing agent in the Calvin cycle, providing the necessary high-energy electrons to convert carbon dioxide into glucose. It acts as a source of electrons in the reduction of 3-phosphoglycerate to glyceraldehyde 3-phosphate (G3P).
7. Recycling of ADP, NADP+, and Pi: As ATP is hydrolyzed to ADP and inorganic phosphate (Pi) during the Calvin cycle, ADP and Pi are regenerated in the light-dependent reactions. Similarly, NADP+ is regenerated from NADPH.
8. Continuous Cycle: The production of ATP and NADPH in the light-dependent reactions and their utilization in the light-independent reactions create a continuous cycle, ensuring the flow of energy and reducing power required for photosynthesis.
In summary, ATP and NADPH act as energy and reducing power carriers, respectively, connecting the light-dependent reactions that capture light energy with the light-independent reactions that utilize this energy to produce glucose. Their continuous generation and utilization ensure the efficiency and functionality of photosynthesis.

Explain why we experience seasons. In your explanation you need to include references to the Earths motion, characteristics, and positions that cause the seasons
Answers
Seasons are a result of the Earth translation motion, during which the Earth changes its distance to the sun. Moreover, the Earth's axial tilt causes the rays from the sun to reach the Earth at different angles with different incidence and magnitude throughout the year. Even though, these changes do not affect the entire earth in the same way, so another factor to take into consideration is the latitude, for example, lower latitudes at the regions near the equator don't experience significan't changes in the sunlight incidence making seasons almost indistinguishable, while the opposite happens, and increases at the same time latitude is higher.

Answers
Answer:
Option B
Explanation:
It is a liquid because it flows.
Carmen's sample of matter is clear, smells sour, thick but flows when poured. The best conclusion about Carmen's sample is that it is liquid.
There are 3 states of matter, basically:
SolidLiquidGasesSolid substances do not move or flow in any way because their molecules are fixed.
Gaseous molecules take the shape and the volume of containers
Liquid molecules only take the shape of containers.
Liquid and gases have molecules that can move and be made to flow. However, while gases will flow out automatically from opened containers, liquids cannot, unless they are poured.
Hence, since carmen's sample of matter can only be made to flow when poured, it is safe to conclude that it is a liquid.

.An athlete went for a swim to cool down faster after an hour of an intense exercise routine. What heat emission mechanism makes the athlete cool down faster in water? A - Heat convection B - Sweat evaporation C - Heat conduction D - Heat exchange
Answers
Answer:
Explanation: The heat emission mechanism that makes the athlete cool down faster in water is option A, Heat convection.
Heat convection is the transfer of heat through the movement of a fluid or gas. When the athlete is submerged in water, the water surrounding the athlete's body is cooler than the athlete's body temperature, so heat is transferred from the athlete's body to the surrounding water through convection. This causes the athlete's body temperature to decrease, making them cool down faster.
Heat conduction is the transfer of heat through direct contact between two objects. This mechanism does not apply in this case as the heat is transferred from the athlete to water not by direct contact but by movement of fluid.
Heat exchange is the transfer of heat between two substances or systems. It's a general term but in this case, it is referring to the heat exchange through convection.
Sweat evaporation is the process of sweat turning from a liquid to a gas. As the athlete is submerged in water, sweat evaporation will not play any role in cooling down the athlete.

Name three different cells in a leaf that contain chloroplast. Please help
Answers
The LEAF as a photosynthetic organ includes the following cells which contains CHLOROPLASTS
• the palisade mesophyll
• the spongy mesophyll and
• the stomatal guard cells
The LEAFS are the main organ of photosynthesis. Photosynthesis is the process by which green plants manufacture their food in the presence of sunlight. This takes place in the CHLOROPLASTS of these plant. CHLOROPLASTS are structures that contains chlorophyll which traps in energy from the sunlight.
The mesophyll tissues are located between the upper and the lower epidermis of the leaf. The palisade mesophyll, which is found at the upper part, contains numerous CHLOROPLASTS and is the main site of photosynthesis in the leaf.
The spongy mesophyll is located at the lower part of the epidermis. They are irregularly arranged with air spaces between them which are linked to the stomatal openings. They also contain CHLOROPLASTS.
The stomatal guard cells are a pair of bean-shaped cells which controls the opening and closing of stomata. These cells contains CHLOROPLASTS which contributes to the movement of stomata.
Therefore the three different cells of the leaf that contains CHLOROPLASTS are the palisade mesophyll, the spongy mesophyll and the stomatal guard cells.

How is transcription similar to replication and how is it different?
Answers
Answer:
Transcription and replication are important processes that occur in cells but have distinct differences.
Similarities between transcription and replication:
1. Both transcription and replication involve the synthesis of nucleic acids. In replication, DNA is copied to produce an identical DNA molecule, while in transcription, DNA is used as a template to produce RNA.
2. Both processes occur in the nucleus of eukaryotic cells, although replication also occurs in the cytoplasm of prokaryotic cells.
Differences between transcription and replication:
1. Template: In replication, the entire DNA molecule serves as the template for copying. However, in transcription, only a specific DNA segment, called a gene, serves as the template for synthesizing an RNA molecule.
2. Product: Replication results in the production of an identical DNA molecule, while transcription produces an RNA molecule that is complementary to the DNA template.
3. Enzymes involved: Replication requires the involvement of multiple enzymes, including DNA polymerase, helicase, and ligase. Transcription, on the other hand, involves RNA polymerase, which catalyzes the synthesis of RNA from the DNA template.
4. Base pairing: During replication, DNA bases pair with their complementary bases (A with T and C with G) to produce an exact copy. In transcription, RNA bases pair with complementary DNA bases (A with U and C with G), resulting in an RNA molecule complementary to the template DNA strand.
Overall, while transcription and replication involve the synthesis of nucleic acids, they differ in terms of their templates, products, enzymes involved, and base pairing patterns. These processes are essential for cell function and crucial in genetic information transfer and maintenance.

Answers
If we compare the prey data for each region, we can see total prey biomass is fairly similar; but the growth rate is slightly lower, while the density is far lower in Pilanesburg, which seems to be the main reason why the population of wild dogs there is so low, and also why more area is needed.
This means that prey biomass and density are the main factors that limit the wild dog population in Pilanesburg (B).
