Final answer:
The menstrual cycle is responsible for causing menstruation. It involves the shedding of the endometrium from the uterus and is controlled by hormones from the brain and ovaries.
Explanation:
The process responsible for causing menstruation is called the menstrual cycle. It is a natural monthly cycle of processes and events in the ovaries and uterus of a sexually mature female. The menstrual cycle is necessary for the production of eggs and the preparation of the uterus for pregnancy.
During the menstrual cycle, the endometrium of the uterus is shed from the body. The cycle is controlled by hormones from the hypothalamus, pituitary gland, and ovaries. Ovulation, the release of an egg from an ovary, is part of the menstrual cycle. If pregnancy does not occur, the endometrium builds up again during the cycle and is shed during the next menstrual period.

"susan is consuming 70 grams of protein per day on her 2,000-kilocalorie-per-day diet. what percent of susan's diet is protein?"
Final answer:
To determine the percentage of Susan's diet that is protein, multiply the amount of protein she consumes daily (70 grams) by the number of calories per gram of protein (4), and then divide that number by her total daily caloric intake (2,000 calories) and multiply by 100 to get the percentage, which is 14%.
Explanation:
To calculate the percentage of Susan's diet that is protein, we need to know how many calories are in a gram of protein and then how many of those calories are part of her overall 2,000 kilocalorie daily intake. A gram of protein has 4 calories. If Susan is consuming 70 grams of protein a day, she's getting 70 grams * 4 calories/gram = 280 calories from protein.
Now to find the percentage of her diet that is made up of protein, we use the formula:
Percentage of calories from protein = (Calories from protein / Total calorie intake) * 100
Percentage of calories from protein = (280 / 2000) * 100
Percentage of calories from protein = 14% of Susan's diet is protein.

Catalysts increase the rate of a reaction by
Answer:
Decreasing the activation energy of the reaction.
Explanation:
Catalyst may be defined as the substance that increase the rate of a bio chemical reaction. The catalyst does not change the equilibrium of the reaction.
The catalyst increase the rate of a chemical reaction by decreasing the activation energy of the reaction. The activation energy is the minimum amount of energy required for the conversion of reactant into product. The catalyst increases the effective collision between the molecules and decreases the activation energy. Hence, increases the rate of a reaction.

The action potential propagates along the sarcolemma. as the action potential spreads down the t tubules of the triads, voltage-sensitive tubule proteins change shape. how does the shape change of these proteins lead to contraction?
The change in shape of voltage-sensitive tubule proteins initiates an action potential, leading to the entry of sodium ions (Na+) and the release of calcium ions (Ca²+) from the sarcoplasmic reticulum. These calcium ions bind to troponin, changing its configuration, and thereby revealing the binding sites for myosin on the actin filaments. This initiates the muscle contraction process.
Explanation:The process leading to muscle contraction begins when the neurotransmitter, Acetylcholine, triggers an action potential within the sarcolemma. This action potential travels down the T Tubule, causing voltage-sensitive tubule proteins to change shape.
As the action potential reaches the membranes within the T Tubule, voltage-gated sodium channels open. This change leads to the depolarization of the membrane as sodium ions (Na+) enter the muscle fiber. This initiates excitation-contraction coupling, and the action potential spreads across the entire muscle fiber's membrane.
The change in voltage stimulates the release of calcium ions (Ca²+) from the sarcoplasmic reticulum, a calcium storage site within the cell. The calcium then binds to troponin, which alters its confirmation and moves tropomyosin off the active sites of actin, allowing the myosin heads to attach, leading to muscle contraction.
The contraction will continue as long as ATP is available to fuel the process, and calcium ions are present in the sarcoplasm.

Compare and contrast the advantages and disadvantages of sexual and asexual reproduction
Final answer:
Asexual reproduction allows for rapid and mate-free offspring production, advantageous in stable environments but less so in changing ones due to lack of genetic diversity. Sexual reproduction is slower and requires a mate, yet it offers genetic diversity, which aids survival and adaptation in unpredictable environments.
Explanation:
Advantages and Disadvantages of Sexual and Asexual Reproduction
Animals produce offspring through sexual and asexual reproduction, and both methods come with their own sets of pros and cons. Asexual reproduction results in offspring that are genetic clones of the parent, which means they are well-suited for stable environments but potentially at risk in changing conditions due to the lack of genetic diversity. Sexual reproduction, while more energy-intensive as it requires finding a mate, generates offspring with genetic variation, which can be a significant advantage in unpredictable environments.
The main advantages of asexual reproduction are the ability to quickly produce large numbers of offspring without the need for a mate, which is beneficial for colonization of new habitats and rapid population growth. However, the disadvantage is that offspring lack genetic diversity, making them more vulnerable to environmental changes and diseases. On the flip side, the advantages of sexual reproduction include the production of genetically diverse offspring, which allows for better survival through changing conditions and potential adaptation to new environments.
A rapid evolutionary advantage of sexual reproduction is the enhanced potential for adaptation due to genetic recombination, which asexually reproducing species might lack. However, asexual reproduction can still be advantageous in certain environments and life strategies, illustrating the complexity of these reproductive strategies in the natural world.

Which process involves the movement of molecules or atoms down a concentration gradient across plasma membranes?
Answer:
Diffusion is the process involves the movement of molecules or atoms down a concentration gradient across plasma membranes. It does not require any use of energy so it is a type of passive transport.
Diffusion can be divided into simple diffusion and facilitated diffusion. In simple diffusion, a molecule dissolve with the plasma membrane and transported inside the cell along the concentration gradient.
Facilitate diffusion also involved in transport of molecules along the concentration gradient but in this case, the molecules are transported by carrier protein present in the plasma membrane. Facilitated diffusion has a fast rate of transport than simple diffusion.
In the area with the largest sea lamprey population, what is being done to reduce this population?
In the area with the largest sea lamprey population, some of the things that are done to reduce this population will be:
Use of lampricide.Construction of barriers in order to block the migration of sea lamprey.Use of sterile male release techniquePopulation simply refers to all the inhabitants that are in a particular area. It is a community of plants, animals, or humans where interbreeding takes place.Sea lampreys are bad as they have a negative effect on the population of fish. It should be noted that once a fish has been bitten by sea lamprey, rather than producing eggs and increasing the population of fishes, the fishes that are bitten spend more time healing.To control sea lampreys, it's vital to use lampricide which is a chemical that destroys the larvae of lampreys before they develop into adults. Also, the construction of barriers can be done in order to block the migration of sea lamprey.In conclusion, one can also make use of the sterile male release technique in order to control the pest.
