The possibility that a rodent species may have survived because of a change in its environment that is capable of eating plants that survive the changed environment. So, the correct option is (D).
What is Adaptation?Adaptation is defined as the process by which a species adapts to its environment as a result of natural selection acting on variation over many generations.
Organisms are adapted to their environment in their structure, physiology, and genetics, in their locomotion or dispersal, in their means of defense and attack, in their reproduction and development, and in other respects.
It is described as the ability of an organism to adapt to its environment and change through time, referring to the term "adaptation theory", known as the "survival of the fittest" idea. In this instance, rodents become able to eat plants that survive the changed environment.
Thus, the possibility that a rodent species may have survived because of a change in its environment that is capable of eating plants that survive the changed environment. So, the correct option is (D).

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.

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.

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.

A food chain or food web can provide good information including _____.
how much energy is transferred from one organism to another
the types of food that are best for you to eat
the eating patterns of organisms
the flow of energy in an ecosystem
Answer:
the flow of energy in an ecosystem
the eating patterns of organisms
how much energy is transferred from one organism to another
Explanation:
A food web is an interconnection of multiple food chains and a practical representation of what-eats-what in an ecosystem, while a food chain is a linear sequence of how nutrients and energy (in the form of food) are transferred from one organism to another organism in an ecosystem. A food web contains many interconnected food chains. A food web or food chain provides information about how organisms are connected, the eating patterns of organisms, and the flow (or the amount) of energy that is transferred from one level to another through different organisms in an ecosystem.

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.
In task 2 I only did part D
answer:
Two independent sets of observations on sand activities in relation to the flowing river are recorded as the water passes through the meandering river. Stream abrasion can affect the morphology of a stream or river dramatically over time. Because the water can start erosion with anything near it, erosion can impact human communities near rivers.

How does your digestive and musculoskeletal system work together
Explanation:
The muscular system allows for movement within the body, for example, during digestion or urination. Smooth muscles in the gastrointestinal or GI tract control digestion.
Part A
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 is meiosis?
Meiosis is a process in which a single cell divides into two identical daughter cells and the process is known as cell division.
Meiosis is a type of cell division in sexually reproducing organisms that reduces the number of chromosomes in gametes.
The main functions of meiosis are mentioned below:
1) Meiosis in humans causes the decrease or reduction of the number of chromosomes in normal cells which is specifies as production of gametes.
2) Meiosis induces genetic variation by the process of recombination.
The main objective of meiosis is to produce gametes, the sperm and eggs, with half of the genetic character of the parent cell.Meiosis is a process in which a single cell divides into two identical daughter cells and the process is known as cell division.
