Explain why Halley’s Comet is part of our solar system.
Answer:
because they were originally long period comets whose orbits were perturbed by the gravity of the giant planets and directed into the inner solarsystem
Halley's Comet is part of our solar system because it orbits around the Sun.
What is Halley's Comet?Halley's Comet is a periodic comet that follows a predictable orbit around the Sun and brings it close to the Earth once every 75-76 years. Halley's Comet originated from the Kuiper Belt, which is a region of the solar system containing icy objects.
When the comet approaches the Sun, the comet's ice and dust sublimate, which creates a bright coma that can be seen from Earth. The comet's nucleus is about 11 kilometers in diameter.
Halley's Comet is observed by humans for thousands of years. The regular return of comets allows scientists to study them in detail, thereby, helping us understand comets and the early solar system.
Therefore, Halley's Comet is part of our solar system because it orbits around the Sun like the other planets or objects in our solar system.

A man with type A blood marries a woman with type B blood. Their child has type O blood. What is the genotype of the woman
Answer:
The genotypes of the two parents are AO and BO. Blood types A and B are dominant over blood type O,
Explanation:
An offspring inherits their genotype (genetic makeup) from their parents with each parent providing one allele for a given trait. An offspring need only inherit one dominant allele to have the phenotype (observable physical characteristic) of that trait and must inherit a recessive allele from each parent in order to have that phenotype. For example, brown hair is a dominant trait and only one parent must provide that allele for hair color in order for their offspring to have brown hair. In order for the recessive trait of blonde hair to be the phenotype of the offspring, each parent must provide the blonde hair allele.

Heyy.
So i did the alternative activity for this assignment.
In task one I only did part F:
answer:
Weathering damage on Cleopatra's Needle, an Egyptian obelisk in Central Park, New York City, is compared to known weathering rates of granites in various regions. The detrimental influence of the city's environment in 83 years of exposure has been attributed by textbook authors to damage to this coarse-grained foliated granite. As evidenced by the original depth of inscription in New York, about 11/2 inches of maximum surface reduction had occurred. Granite reduction rates in humid regions were calculated to be as low as 0.0076 mm per year, and even lower in deserts. The majority of the damage to the obelisk was caused by rising moisture laden with sulfate salts in Egypt, according to the findings. The hydration pressure of these salts, combined with frost wedging, is responsible for the major damage to the monument, which happened during its first few years in New York.

Which class of drugs for human immune deficiency virus infection reduces how well HIV genetic material can be converted into human genetic material
The class of drugs for human immune deficiency virus infection which reduces how well HIV genetic material can be converted into human genetic material is called The Nucleoside Reverse Transcriptase inhibitors (NRTIs)
Meaning of HIV and NRTIsHIV also called human immunodeficiency virus is an infection that always attack the body immune system but majorly the white blood cells which is called the CD4 cells. The human immunodeficiency virus destroys these CD4 cells thereby causing a persons immune system to be weak and unable to fight other infections, leading to ill health.
The NRTIs also known as the Nucleoside Reverse Transcriptase inhibitors prevent viral replication, binding and interaction with the CD4+

How does gene pool and allele frequency terms relate to another??
Answer:
Allele frequency is how often an allele occurs in a gene pool
Explanation:
Allele frequency refers to how common an allele is in a population. It is determined by counting how many times the allele appears in the population then dividing by the total number of copies of the gene. The gene pool of a population consists of all the copies of all the genes in that population.
Name 3 factors you can use to determine if organisms are apart of separate species.
Answer:
According to the biological species concept, organisms belong to the same species if they can interbreed to produce viable, fertile offspring. Species are separated from one another by prezygotic and postzygotic barriers, which prevent mating or the production of viable, fertile offspring.

How many spermatids result from one spermatogonium?.
Four (4) spermatids result from one spermatogonium. Details about spermatogenesis can be found below.
What is spermatogenesis?Spermatogenesis is the process by which sperm cells are produced from the testes of a male animal.
Spermatogenesis involves series of mitotic and meiotic divisions that finally result into the haploid sperm cells.
Spermatids are haploid cells produced by meiosis of a spermatocyte that develops into a spermatozoon.
The spermatogonium divides mitotically into primary spermatocyte which then develops into secondary spermatocyte via meiosis. Each secondary spermatocyte forms 4 spermatids.

You will create a molecular clock model for an arthropod gene. Follow these guidelines to make your model:
Your timeline will span from 90 million years ago to the present. The common ancestor in your model is an arthropod that lived 90 million years ago. The gene that you’ll track codes for a protein in the species’ venom.
The DNA sequence you’ll track contains 10 nitrogen bases. You can choose the order of the bases and where the mutations occur.
This gene mutates at a rate of approximately 0.76 base pairs every 17.1 million years. To build your model, calculate the estimated time period it takes for 1 base pair to mutate.
The first time period will only show the common ancestor. At the beginning of the second time period, three lineages will diverge from the common ancestor, each with a different mutation in their gene sequences.
The first and third descendant species will survive for the rest of the timeline. The second descendant species was extinct 50 million years ago.
Calculate how long it will take for one full base pair mutation to occur. Explain your reasoning by constructing a mathematical equation.
Based on the mutation rate of the molecular clock, it will take 22.5 million years for one full base pair mutation to occur.
What is a molecular clock?A molecular clock is a biomolecule which is chosen to serve as a clock due to its periodical changes in a regular pattern.
Mutation in genes can serve as molecular clock.
The mutation in the gene of coding for the venom mutates at a rate of 0.76 base pairs every 17.1 million years.
It will take 17.1/0.76 = 22.5 million years for 1 base pair to mutate.
Therefore, it will take 22.5 million years for one full base pair mutation to occur.

What if the gas molecules collide at very low temperatures? will that change what happens? why?.
Answer:
At low temperatures, gas particles have less kinetic energy, and therefore move more slowly; at slower speeds, they are much more likely to interact (attracting or repelling one another) upon collision
If the gas molecules collide at very low temperatures then the collision will be slower as the intermolecular forces are stronger at the lower temperature and it is demanding situation to give high energy in order to break the bonds.
What is the fate of collision of gas molecules ?The fate of gas molecules is the formation of making gases compounds by making the elements bind together in order to form a new compound.
At the lower temperature, the average velocity of the molecules that are possessed by the molecules is decreased therefore the gas molecules will have lesser kinetic energy and they will move very slowly in order to form a new compound.
Gases do not exert much of force on each other but they do possess a collision with each other and the collision molecules are elastic so as they are able to do collision.
