What is a DNA helix?
A DNA molecule is made up of two linked strands which wind around each other to resemble a twisted ladder in the helix-like shape. Each of the DNA strand has a backbone which is made up of alternating sugar molecules which are deoxyribose and phosphate groups. These are attached to each sugar molecule which is one of four nitrogenous bases which include adenine (A), cytosine (C), guanine (G), and thymine (T).

PLEASE HELP I"LL GIVE YOU BRAINLIEST How does your body work? I need a simple but well explained answer. WORTH 100 POINTS!!!
Answer:
Explanation:
Our bodies are made up of many different systems that work together to keep us alive and healthy. These systems include the circulatory system, the digestive system, the endocrine system, the immune system, the muscular system, the nervous system, the reproductive system, the respiratory system, and the skeletal system.
The circulatory system is made up of the heart, blood vessels, and blood. The heart pumps blood, which carries oxygen and nutrients to all the cells in our body. The blood also carries waste products away from the cells to be eliminated.
The digestive system breaks down the food we eat and absorbs the nutrients our body needs. The endocrine system produces hormones that help to regulate many of our body's functions.
The immune system helps to protect our body from infections and diseases. The muscular system allows us to move and perform physical tasks.
The nervous system consists of the brain, the spinal cord, and a network of nerves that carry messages to and from the brain and the rest of the body. The reproductive system is responsible for the production of offspring.
The respiratory system brings oxygen into our body and removes carbon dioxide, a waste product. The skeletal system is made up of bones and helps to support and protect our body.
How does this hierarchy relate to the approach we take in studying anatomy and physiology?
Answer:
As we discuss further into Anatomy & Physiology I ask that you keep this hierarchy in mind, for one complexity cannot exist without its smaller counterpart.
Explanation:
Hierarchy is related to the approach we take in studying anatomy and physiology as organisms are classified into different classes on the basis of their structure and functions.
What is Hierarchy?Hierarchy can be defined as the taxonomic classification of living organisms in the successive levels of complexity. In this, the highest rank in such a classification system is the Kingdom while species is the lowest rank of the classification system. Hierarchy can be classified into two types namely obligate hierarchy and intermediary hierarchy.

genetic drift is a process that can cause random fluctuations in the frequency of alleles in a population from one generation to the next.
true or false
Genetic drift is a process that can cause random fluctuations in the frequency of alleles in a population from one generation to the next. The correct answer is true.
Genetic drift is a process that can cause random fluctuations in the frequency of alleles in a population from one generation to the next. It occurs because of the random sampling of individuals that contribute their genes to the next generation. In small populations, the impact of genetic drift can be significant, leading to the loss of genetic diversity and the fixation of certain alleles. In larger populations, the impact of genetic drift is much smaller and is generally overshadowed by other forces such as natural selection.

A watershed is an area of land that catches precipitation and drains to rivers and lakes. Which of the following conclusions can be drawn about the quality of water in the watersheds of the United States in 2000?
A river's basin is the area of land that it and its tributaries drain.
How do watersheds affect water quality?Water transports toxins and sediment as it flows over, through, and into the watershed. If left untreated, these pollutants are conveyed by runoff from rain and snowmelt directly into rivers.

The following are molecules that can be converted into amino acids when they enter the energy pathway of cellular respiration: Pyruvate, Acetyl CoA, and Intermediates in the Krebs cycle. True. All is correct.
Cellular respiration is a process of overhauling complex organic molecules to produce energy that is used for cell needs. Cells need energy to perform various tasks in the body, including moving muscles, keeping vital organs working, and cell division. The process of cellular respiration begins with the glycolysis stage which produces pyruvate. Then the Krebs cycle stage where pyruvic acid is converted to acetyl CoA through an event called oxidative decarboxylation which is then converted to produce ATP.
When the body is starving, the excess amino acids in the body can be diverted to the pathway of glucose catabolism. Amino acids whose amino groups have been removed can enter metabolic pathways via pyruvate, acetyl CoA, and intermediaries in the Krebs cycle.

electrostatic sheathing of lipoprotein lipase is essential for its movement across capillary endothelial cells.T/F
False. Lipoprotein lipase doesn't bear electrostatic sheathing for its movement across capillary endothelial cells.
Rather, it's transported across the cell membrane via a process known as transcytosis. In this process, lipoprotein patches are gulfed by the cell membrane and ultimately released into the other side of the cell membrane. This occurs without the need for electrostatic sheathing. Lipoprotein lipase is a critical enzyme that helps to hydrolyze triglycerides and other lipids in the blood and acts as a major lipolytic enzyme. This enzyme is essential for the digestion and immersion of salutary fat, the conservation of lipid homeostasis, and the regulation of adipose acid metabolism.

False. The passage of lipoprotein lipase across capillary endothelial cells is not protected by electrostatic sheathing.
Transcytosis, a technique, is used to move it across the cell membrane. The cell membrane engulfs the lipoprotein patches during this process, releasing them onto the other side of the cell membrane in the end. Without the use of electrostatic sheathing, this happens.

The translation is the protein synthesis stage at which amino acids are added to the growing chain as rRNA and tRNA read and recognize mRNA codon sequences. In the image, there are only intermediate codons. By clicking on the right arrow you will get to the stop codon.
What is translation?
The translation is a step in protein synthesis that follows transcription. It occurs in the cytoplasm of the cell and involves mRNA, rRNA, tRNA, and amino acids.
rRNA reads mRNA and the associated tRNA adds amino acids to grow the new protein according to the codons being read.
Codons are three base sequences. There is always a start codon (AUG) which indicates where protein growth must occur, a stop codon (UAA, UAG, or UGA), which indicates where protein synthesis ends, and intermediate codons, which indicate which amino acids are part of the molecule.
In the exposed example, after the AUG start codon (blue box) there are several intermediate codons (gray boxes), and finally a stop codon (pink box). Since this is only an image I can not complete the protein, so I will show you which are te intermediate codons.

What would happen if a major predator was added to the food web?
Answer:
If a major predator was added to a food web, it could have a variety of impacts depending on the specific species and ecosystem in question. Some potential outcomes could include:
Changes in population dynamics: The addition of a major predator could lead to changes in the populations of other species in the food web. For example, if the predator preys on a particular species, that species may decline in population, while other species that are not preyed upon may increase in population.
Trophic cascades: The addition of a predator can also lead to trophic cascades, where changes at one level of the food web ripple down to other levels. For example, if a predator reduces the population of a particular prey species, this could lead to changes in the populations of species that depend on that prey species for food.
Ecological balance: The addition of a predator could potentially restore balance to an ecosystem if it is introduced to control an overabundant prey species. This can help to prevent overgrazing or other negative impacts on the ecosystem.
Extinction risk: In some cases, the addition of a major predator could pose a threat to other species in the food web, potentially leading to extinction if the predator preys on a vulnerable species.
