The homologous traits of related species can be explained by the Theory of Evolution. This theory states that species evolve over time from a common ancestor.
As species diverged from each other, they adapted to the new environment and acquired new traits. This process is called speciation, and it is responsible for the variety of species found on earth today.
The shared homologous traits of related species are evidence of a common ancestry. For example, the wings of a bat and the wings of a bird have homologous traits despite being different species. This is because they share a common ancestor, and have evolved over time to meet the environmental needs of the particular species.
Another reason why related species share homologous traits is because they live in the same geographical area. This means that they are exposed to the same environmental conditions and face similar evolutionary pressures. This means that they are more likely to share similar traits, as these are the traits which are beneficial for survival in the particular environment.

Hypothesize how some people have red hair through viable errors. Explain your answer in 1-2 sentences.
Some people have red hair through the viable errors. These variable errors are called as mutations.
What are Mutations?A mutation is an alteration in the genetic material of the cell such as the nucleic acid sequence of the genome of an organism, virus, or the extra-chromosomal DNA which is present in the mitochondria and chloroplast of the cell. Viral genomes contain either DNA or RNA as the genetic material.
A viable error in the genetic material is a mutation which remains for the rest of life, so we can say that some people have red hair which is a rare trait due to viable errors or the mutations in the genetic code. Red hair is a recessive gene in the DNA, which means red hair only occurs when a person has two copies of the same gene.

what mechanisms have evolved in animals with (a) external fertilization and (b) internal fertilization that help offspring survive to adulthood?
Fertilization is the process through which animals and other living things reproduce and create zygotes. Based upon how the male and female gamete merge, they can be divided into internal and exterior fertilisation.
As a means of survival, animals that display external fertilisation frequently produce a lot of eggs. A lot of eggs can aid in boosting the reproduction rate because they can be damaged during external fertilisation.Fertilization is the process through which animals and other living things reproduce and create zygotes. Based upon how the male and female gamete merge, they can be divided into internal and exterior fertilisation.In internal fertilisation, the eggs are either grown in a secure reproductive canal or are protected when laid by a shell, a defence mechanism exhibited by animals like mammal, reptiles, and birds.

What is the result of mitosis? question 14 options: two genetically identical daughter cells two genetically unique daughter cells four genetically identical daughter cells four genetically unique daughter cells
Mitosis results in the formation of two daughter cells that are genetically identical to each other and to the parental cell.
A diploid cell begins with 2N chromosomes and 2X DNA. The cell is still genetically diploid (2N chromosome number) after DNA replication, but it has 4X DNA content because each chromosome has replicated its DNA. Each chromosome is now made up of a pair of identical sister chromatids that have been joined together. Sister chromatids separate and move to opposite ends of the dividing cell during mitosis. Mitosis results in the formation of two identical cells, each with 2N chromosomes and 2X DNA content. Except for germline cells, which undergo meiosis (see below) to produce gametes, all eukaryotic cells replicate via mitosis (eggs and sperm).

Think of ways in which scientists are presently challenging our ideas about the Universe?
Answer: How fast the universe is growing
Explanation: Scientists believe that our universe is constantly growing, but no scientists nor astronomers agree how fast
There are several ways in which scientists are currently challenging our ideas about the Universe:
Dark Matter and Dark Energy: Scientists have observed that the Universe contains much more matter than what can be accounted for by the visible matter we can see. This has led to the concept of dark matter and dark energy, which make up most of the Universe but remain mysterious and unobserved. Scientists are actively searching for evidence of these mysterious components of the Universe.Inflation Theory: The Inflation theory proposes that the universe underwent a rapid expansion in the first fraction of a second after the Big Bang. It explains the uniformity of the universe and is supported by recent observations of the cosmic microwave background radiation.The Multiverse Hypothesis: The multiverse hypothesis suggests that there may be multiple universes beyond our own, each with its own set of physical laws and characteristics. Some scientists have proposed that the multiverse may explain the existence of dark matter and dark energy, the values of physical constants, and the nature of the Big Bang.Quantum Mechanics and General Relativity: The laws of quantum mechanics and general relativity are the foundation of our current understanding of the nature of space-time and the behavior of matter. However, they are incompatible and scientists are trying to find a way to unify them in a theory of quantum gravity.The nature of black holes: Scientists have recently made observations of the event horizon of black holes and they were different from what they expected, leading to new questions about the nature of black holes.
These are just a few examples of how scientists are currently challenging our ideas about the Universe. Scientific research is a continuous process and new discoveries are being made all the time, leading to new questions and new challenges to our current understanding of the Universe.

what do you think happens to the rate of insulin secretion when blood glucose levels fall? what kind of feedback pathway is taking place?
when blood glucose levels fall the rate of insulin secretion decreases. This is negative feedback.
When blood sugar enters cells, blood sugar levels fall, which tells insulin to do the same. In order to ensure that energy is constantly available, even if you haven't eaten in a while, lower insulin levels signal the liver to release stored blood sugar.
When blood sugar levels fall too low, the amount of insulin reduces and other pancreatic cells release glucagon, which prompts the liver to release glucose back into circulation after converting stored glycogen. As a result, blood sugar levels return to normal.

If a cell at metaphase of mitosis which contains 20 sister chromatids, Then, there will be 10 pairs of chromosomes will present in a somatic cell.
The normal number of chromosomes in a cell is 10 and there are usually 5 pairs of chromosomes. Since there are now 20 chromatids, duplication has occurred and they should become two identical pairs (sister chromatids). Therefore, there are 10 centromeres. If there are 20 centromeres in anaphase, there are 20 chromosomes in the dividing cell. As a result, each terminal pole of a dividing cell acquires 10 chromatids and each chromatid becomes a chromosome of the cell at the metaphase. After division, each chromosome consists of only one chromatid, a total of 23 chromatids.

How does producing an overabundance of offspring help sea turtles overcome the many dangers that their offspring encounter and ensure that their species population numbers stay relatively steady?
Answer: Sea turtles produce many offspring so that if some die, there will still be some that live and carry on the species.
Explanation:
Sea turtles can be killed by birds, poachers, people (Most likely on accident), or just any other unforeseen circumstances when trekking from their eggs to the sea when they hatch. Sea turtles produce many offspring so if a few do die, there will still be (hopefully) a sufficient amount to carry on the species.
Hope this helped!
By producing an overabundance of offspring, the sea turtles increase their chances of survival.
What are sea turtles?Large, air-breathing reptiles that live worldwide in tropical and subtropical oceans are known as sea turtles. They lay numerous eggs in each nesting season. This strategy of producing many offspring is known as “bet-hedging.”
They produce an overabundance of offspring to help ensure that some will survive despite the dangers face by them. This strategy also helps to maintain the population numbers of sea turtles over time, as the survival of some offspring will help to replace those lost to predation or other factors.
Additionally, by laying their eggs on multiple beaches in different regions, sea turtles increase their chances of survival by diversifying their genetic makeup and reducing the risk of a single catastrophic event wiping out the entire population.

According to Henneman's size principle, Jim's muscle (when He lifting weights, holding a 20lb weight down by his side, he bends his arm at the elbow, contracting his bicep, and holds the position until he reaches muscle fatigue) recruited in order of size when under load. This means that slower, lower force, more fatigue-resistant muscle fibers are recruited before faster, higher force, less fatigue-resistant muscle fibers.
The foundation for size-ordered activation or recruitment of motor units during movement is Henneman's size principle, which links the input and output characteristics of motoneurons and their muscle fibers to size. Regardless of whether the muscles are self- or cross-reinnervated by the regenerated axons, after nerve injury and surgical repair, the link between motoneuron size and the number and size of the muscle fibers that the motoneuron reinnervates is initially lost but returns over time.
