Answer:
A drought is a long period of abnormally low precipitation. Suppose a drought occurred in Yellowstone National Park from 1916 to 1917. Predict how a graph line would appear for this time period. Explain your prediction in terms of the effect on resource availability.
Explanation: The graph line would have a downward trend because the amount of bison would start to decrease. Droughts heavily impact grassland ecosystems. A drought would increase the risk of a wildfire starting causing the bison to lose their habitat. The drought would also result in reduced plant growth. Therefore the bison would die off either because they were impacted by a wildfire, because they don’t have grass to eat etc.

Determine whether each statement describes mitosis, meiosis, or both mitosis and meiosis.
Answer:
DNA replicates in both mitosis and meiosis, Mitosis occurs during growth and development, In meiosis the number of chromosomes reduce by half, Mitosis occurs in all organisms, Meiosis occurs in organisms that sexually reproduce, and chromosomes stay the same in Mitosis.
Explanation:
Mitosis: Occurs during growth and development, Occurs in all organisms, and The number of chromosomes remains the same
Meosis: The number of chromosomes reduces by half, and Occurs in organisms that sexually reproduce
Both: The DNA is replicated.
1. The DNA is replicated: Both Mitosis and Meiosis. In both processes, DNA replication occurs before the division of cells, ensuring that each daughter cell receives a complete set of genetic information.
2. Occurs during growth and development: Mitosis is the process responsible for the growth, repair, and development of multicellular organisms by producing identical daughter cells.
3. The number of chromosomes reduces by half: Meiosis involves two divisions that result in the reduction of chromosome number by half, leading to the formation of gametes (sperm and egg cells) with half the usual number of chromosomes.
4. Occurs in all organisms: Mitosis is a fundamental process occurring in various organisms, ranging from unicellular to multicellular, for growth, tissue maintenance, and asexual reproduction.
5. The number of chromosomes remains the same: In mitosis, the daughter cells have the same number of chromosomes as the parent cell, maintaining the chromosome count.
6. Occurs in organisms that sexually reproduce: Meiosis is specific to organisms that reproduce sexually, as it produces genetically diverse gametes that contribute to the variability of offspring.

How does your body respond to an increase in the waste products of energy production
Answer:
Energy is delivered to the body through the foods we eat and liquids we drink. Foods contain a lot of stored chemical energy; when you eat, your body breaks down these foods into smaller components and absorbs them to use as fuel. Energy comes from the three main nutrients carbohydrates, protein, and fats, with carbohydrates being the most important energy source. In cases where carbohydrates have been depleted, the body can utilise protein and fats for energy. Your metabolism is the chemical reactions in the body’s cells that change this food into energy.
Most of the energy the body needs is for being at rest, known as the Basal Metabolism. This is the minimum amount of energy the body requires to maintain its vital functions such as breathing, circulation and organ functions. The rate at which energy is utilised for such functions is known as the Basal Metabolic Rate (BMR) and varies based on genetics, sex, age, height and weight. Your BMR drops as you get older because muscle mass decreases.
Optimal energy metabolism requires getting sufficient nutrients from our foods, otherwise our energy metabolism underperforms and we feel tired and sluggish. All foods give you energy and some foods in particular help increase your energy levels, such as bananas (excellent source of carbohydrates, potassium and vitamin B6), fatty fish like salmon or tuna (good source of protein, fatty acids and B vitamins), brown rice (source of fibre, vitamins and minerals), and eggs (source of protein). There are actually many foods that provide an abundant amount of energy, particularly those packed with carbohydrates for available energy, fibre or protein for a slow release of energy and essential vitamins, minerals and antioxidants.
Foods are metabolised at a cellular level to make ATP (Adenosine Triphosphate)
by a process known as cellular respiration. It is this chemical ATP that the cell uses for energy for many cellular processes including muscle contraction and cell division. This process requires oxygen and is called aerobic respiration.
Glucose + Oxygen → Carbon dioxide + Water + Energy (as ATP)
Initially, large food macromolecules are broken down by enzymes into simple subunits in the process known as digestion. Proteins are broken down into amino acids, polysaccharides into sugars, and fats into fatty acids and glycerol—through the action of specific enzymes. Following this process, the smaller subunit molecules then have to enter the cells of the body. They firstly enter the cytosol (the aqueous part of the cytoplasm of a cell) where the cellular respiration process begins.

11 Apply If you have a cold that causes congestion in your sinuses, how
might that affect your sense of smell? Support your claim with evidence.
Answer:
If there's a blockage of this channel, like when you have a stuffy nose due to the flu or a cold, odors can't get to the sensory cells the smells stimulate. This results in you losing a lot of your ability to taste the flavor of food. In this manner, your senses of taste and smell work closely together.
Answer:
It will affect your smell because you can have a lot of snot in your nose and your nose will be stopped up with all that stuff.

Explanation:
Why is it that nitrogen is often a limiting plant nutrient, despite the fact that the atmosphere is 80% nitrogen gas (N2)
Nitrogen is a limiting plant nutrient because the bulk of the available nitrogen in the atmosphere is not usable by plants.
Plants are not able to make use of the nitrogen in the atmosphere directly. Atmospheric nitrogen needs to be converted into usable forms before it can be accessed by plants.
The conversion of atmospheric nitrogen to usable form by plants is known as nitrogen fixation and this is achievable by the activities of certain bacteria.

Individuals, as well as industry—and automobile manufacturers in particular have an obligation to work to reduce carbon dioxide emissions that may increase the level of greenhouse gases in the atmosphere. Agree or disagree
It is right that individuals, as well as industry—and automobile manufacturers, in particular, have an obligation to work to reduce carbon dioxide emissions that may increase the level of greenhouse gases in the atmosphere.
Carbon dioxide is a greenhouse gas, which means that it traps heat in the atmosphere. This can lead to climate change, which is already having a number of negative effects on the planet, such as rising sea levels, more extreme weather events, and changes in plant and animal life.
Individuals can reduce their carbon dioxide emissions by making changes to their lifestyle, such as driving less, using less energy at home, and eating less meat. Industry can reduce their carbon dioxide emissions by investing in new technologies, such as renewable energy and energy efficiency.
Automobile manufacturers have a special responsibility to reduce carbon dioxide emissions, as cars are a major source of greenhouse gases. They can do this by designing more fuel-efficient cars and by using alternative fuels, such as electric and hybrid cars.
It is important for everyone to do their part to reduce carbon dioxide emissions. By working together, we can help to protect the planet for future generations.

Describe Hydrogen Bonding.
BEST ANSWER GETS BRAINLIEST
Hydrogen bonding is a interaction between two hydrogen atoms that is very essential for life on Earth. It is notoriously seen between water molecules, and it occurs when there is a slight disbalance in electrical charge between two Hydrogen atoms, and Oxygen atom that comprise water. This slight imbalance makes the Oxygen slightly more electronegative, and the two hydrogen atoms slightly more electropostive. The reason why water when spilled forms globules for this exact reasoning. The slightly positive charged hydrogen feels an electrostatic attraction to the Oxygen atom thus forming a strong bond. An interesting fact that comes from this electrical disbalance is that when salt is added to water, water is able to conduct electricity because of this disbalance in charge it can seperate the sodium chloride lattices into ions.
