B. how environments evolve

Explanation:

Hope this helps

An increase in breathing rate helps the body take in more oxygen and eliminate carbon dioxide, while an increase in heart rate helps the muscles receive more oxygen and nutrients.

While an increase in breathing rate aids in bringing in more oxygen and removing carbon dioxide from the body, an increase in heart rate aids in pumping more oxygen and nutrients to the muscles.

The finding that heart and breathing rates significantly increased throughout a study of physical endurance may suggest that the exercise was successful in testing and enhancing the participants' endurance capacity.

When the body adapts to the greater demands of exercise, an increase in heart rate and breathing rate is normal during physical activity.

Digestive enzymes speedup reactions that break down large molecules of carbohydrates, proteins, and fats into smaller molecules the body can use. Without digestive enzymes, animals would not be able to break down food molecules quickly enough to provide the energy and nutrients they need to survive.

Explanation:

A single gene has three alleles, in a diploid organism, the possible genotypes are six possible genotypes

Each of the alleles in the gene can be represented by the letters A, B, and C. The possible genotypes are: AA, AB, AC, BB, BC, and CC, which is a total of six possible genotypes. Diploid organisms have two sets of chromosomes. Each set consists of one chromosome from each parent. Therefore, the organisms' alleles are found in pairs. For every gene, the organism may inherit two alleles, one from each parent.

Therefore, it is possible to have three different types of alleles for one gene in diploid organisms. If one of the three alleles is rare, its frequency will be low in the population. When two individuals reproduce, the probability of their offspring inheriting one of the three alleles of a gene will depend on the frequency of the alleles in the population. A gene can have three alleles; therefore, in a diploid organism, there are six possible genotypes.

Explanation:

Answer:

Phosphorus contained in agricultural runoff

Explanation:

The term eutrophication refers to the enrichment of surface water with nutrients. This process is related to human pollution activities.

Eutrophication is the biological process that generates in water by an oversupply of nutrients or organic matter. This matter, mainly compounded with nitrogen or phosphorous, favors the phytoplankton multiplication (microscopic plants growing on the water surface) and other aquatic plants. This overgrowth leads to an enhance in primary productivity. Nitrogenated compounds might come from human and animal wastes, while phosphorated compounds might come from fertilizers and other chemicals used in agriculture, that penetrates the soil and reaches water bodies.  

Little by little begin sedimentation is caused by the death of some vegetable organisms that sink in the bottom. These sediments rich in organic matter suffer decomposition in the presence of oxygen.

When oxygen disappears, anaerobic bacteria act and produce fermentation.

On the surface, plants and phytoplankton keep growing, creating a mantle that impedes the light reach deeper areas. The phytoplankton overgrowth on the water surface and the fermentation processes in the bottom originate toxic compounds that damage the animals. Animals die, creating more sediments in the bottom where there are anaerobic conditions.  

Decomposition and fermentation processes increase, producing a bad smell.

The result of eutrophication is the stratification of the water mass:

• First superficial layer, the overgrowth of blue-green algae, produces toxins and interrupts the pass of light to deeper areas. The surface then becomes warmer.

• The second layer might have oxygen available for the animals.

• In the third layer, there is no oxygen, so life is impossible for animals or plants.

• In the fourth layer, there are animals and plant remains in the process of sedimentation.

• At the bottom, there are organic matter and anaerobic bacteria in charge of decomposition and fermentation, through which they produce toxic gases and smell.

Explanation:

Different forms of a gene, such as the ones represented in the alignment between the mouse (Mus musculus) and woolly monkey (Lagothrix lagotricha), are known as alleles.

The alignment provided represents a portion of the gene sequence in two species, the mouse and the woolly monkey. The gene sequence in both species shares a common ancestral form but has diverged over evolutionary time, resulting in slight differences. These differences are termed alleles.

Alleles are alternative forms of a gene that occupy the same position, or locus, on a chromosome. They can arise due to various genetic changes, including single nucleotide substitutions (point mutations), insertions, deletions, or recombination events. In the given alignment, a few nucleotides have been substituted, resulting in different amino acids being coded for in the two species.

The presence of different alleles within a population or between species contributes to genetic diversity. Genetic diversity is important as it provides the raw material for natural selection and adaptation to changing environments. Additionally, alleles can influence traits and phenotypes, including disease susceptibility, response to drugs, or physical characteristics. Therefore, studying and understanding the different forms of genes, such as the alleles in the mouse and woolly monkey, is crucial for comprehending the genetic basis of variation and evolution.

Answer:

During replication, enzymes called helicases untwist the double helix, separating the two parental strands. The point at which the two chains separate is known as the replication fork.

Explanation:

Replication is the process of multiplication of DNA molecules where, from one molecule, two molecules with the same information as the original can be obtained.. Each new replicated DNA molecule has an original strand and a new strand, so replication is semi-conservative.

For replication to occur, the double strand of DNA must be separated, a process that requires the participation of a group of enzymes called helicases. The helicases are responsible for breaking the hydrogen bonds between the complementary bases of one strand and another.

The DNA strands, when separated, form a zipper-like image, and the point of separation between the two is called the replication fork.

The disease characterized by chronic scarring of hepatocytes, is known as "cirrhosis"

Cirrhosis is a progressive liver condition in which healthy liver tissue is replaced by scar tissue, leading to impaired liver function.

It is often caused by long-term liver damage from various factors such as chronic alcoholism, viral hepatitis, autoimmune diseases, or certain genetic conditions.

Cirrhosis can be classified into two main types based on the pattern of scarring and the appearance of the liver:

1. Macronodular Cirrhosis: In macronodular cirrhosis, the liver exhibits larger, irregularly shaped nodules of regenerating hepatocytes surrounded by fibrous scar tissue.

This type of cirrhosis is often associated with alcohol-related liver disease and may result in a more pronounced distortion of liver architecture.

2. Micronodular Cirrhosis: Micronodular cirrhosis is characterized by smaller, uniformly sized nodules throughout the liver.

The nodules in this type of cirrhosis are typically less than 3 mm in diameter and are surrounded by fibrotic tissue.

Micronodular cirrhosis is commonly seen in chronic viral hepatitis and other conditions that cause ongoing liver inflammation and damage.

Both macronodular and micronodular cirrhosis can lead to significant liver dysfunction and complications, including portal hypertension, ascites (fluid accumulation in the abdomen), hepatic encephalopathy, and an increased risk of liver cancer.

Answer:

I don't know

Explanation:

Can't see the photos or answer options.

Photosynthesis: happens within chloroplasts, which are found in most plant cells. Inside this chloroplast, there are sacs called thylakoids. Chlorophyll, a light-absorbing molecule captures solar energy from light; most likely the sun. The captured energy is then converted into ATP and NADPH molecules, also known as chemical energy. The molecules then give off high-energy electrons, and the electrons then move through electron carrier proteins within the thylakoid membrane. The protein within the electrons pumps hydrogen ions into the thylakoid from the surrounding gel-like fluid inside the chloroplast called stroma The hydrogens that get pumped from the electrons then build up within the thylakoid space. The hydrogen ions move back to the stroma through a protein channel. The electron transport chain picks up high-energy electrons and hydrogen ions to form NADPH. The molecules then are able to carry high-energy electrons to the second stage of photosynthesis. As mentioned, chlorophyll molecules release high-energy electrons. The electrons then traveled through an electron transport chain and were then stored in NADPH molecules with hydrogen ions. For this to repeat the electrons and hydrogen ions must be replaced. A water-splitting enzyme removes electrons for the water molecules and then supplied them to the chlorophyll molecules. In doing so, the water molecules split apart into oxygen molecules and hydrogen ions. The ions and chlorophyll are now available for future cycles of light-dependent reactions. The oxygen is released into the air, ending the photosynthesis process.

A simple explanation:  The plant cells convert solar energy(sunlight) into food with the help of H20(water) and C02 (carbon dioxide) in turn in this process the plant releases oxygen.

Kids are most vulnerable to the examples they receive from their immediate caretakers (example, parents, tutors, etc.) Their immediate environment plays a more deterministic role in their behaviour than their hobbies. For example, if a kid is raised in a lovely and supporting family he/she could engage in violent videogames for fun, and not for rehearsal issues (thinking he/she is actually killing). So the early history (wether he suffer any kind of physical/psychological abuse) and the kind of family (wether they are supportive or punitive) plays a critical role in supporting previolent behaviours that videogames or other stuff migth help to develop later on.
