Anoles are a family of lizards found throughout the Americas. Green anoles, Anolis carolinensis, are native to a specific area of Florida. In this area, the primary territory of green anoles was once along the ground and in low-level branches. However, the introduction of brown anoles, Anolis sagrei, from Cuba forced green anoles to shift their territory to the tops of trees. The branches at the treetops are smoother and thinner than those close to the ground. Over time, the toe pads of the green anoles have become larger and stickier.
What is the best explanation for the change in green anoles' toe pads?
A.
Some individuals in the green anole population had mutations that helped them survive and reproduce in the new conditions, so their genes were passed on to the next generation.
B.
Gene flow between the green and brown anoles provided the green anoles with traits that helped them survive and reproduce, and those traits were passed on to the next generation.
C.
The feet of the green anoles became larger and stickier as they used them, which helped the green anoles to better survive, reproduce, and pass the trait on to the next generation.
D.
The change in conditions caused mutations in green anoles that gave them beneficial traits for survival and reproduction, and those mutations were passed on to the next generation.
The answer is; A
The mutation occurs in the population at low rates. However, if these mutations are advantageous, they are maintained in the population and passed on to next generations. This way, the frequency of the mutated alleles increase with each generation. This is how gene change occurs and natural selection.
The correct answer is (A)
Some individuals in a large population are mutated and the mutation was successful as it helped the population to to survive in a better way. The frequency of mutated population started reproducing and was passed on to the next generations. The frequency of mutated population increases with each generation. Some individuals in the green anole population had mutated and that helped them to survive and they successfully reproduced and the trait was passed on to the next generations.

Is space a limiting factor for plant population? Name tow ways
Yes, space is a limiting factor for the plant population.
The space occupied by the plant on the earth determines the amount of the nutrition derived from the soil, if the land is occupied by many plants, the space for the adherence and the nutrient intake would be a factor for competition.
All the plants need sunlight to survive, as it is the source of energy for them. In case, a tree or a plant occupies a huge aerial space, then it would shade the sunlight for the smaller plants, hence, the plants cannot grow in completely shaded region.
In camellia plants, flower color is controlled by a single gene with codominant alleles. A camellia plants with red flowers (RR) is crossed with a camellia plant with white flowers (WW). What are the expected phenotypes of the offspring of this cross?
A. All will have both red and white flowers.
B. Half will have red flowers and half will have white flowers.
C. All will have red flowers.
D. All will have pink flowers.
The correct answer is: A. All will have both red and white flowers.
If camellia plant with red flowers (RR) is crossed with a camellia plant with white flowers (WW), then
P: RR x WW
F1 generation: RW RW RW RW
This means that all of the offspring will have both colors. Codominant means that red and white are equally dominant (both expressed).
In a cross between camellia plants homozygous for red and white flower alleles which are codominant, all offspring will have both red and white flowers visible.
Explanation:In camellia plants, flower color is controlled by a single gene with codominant alleles. The red (RR) and white (WW) flowers represent plants that are homozygous for the red and white alleles respectively. When these plants are crossed, the offspring receive one allele for red and one for white from the parent plants. As they are codominant, both alleles will express themselves, resulting in a phenotype where both red and white are visible. Therefore, the correct answer is A. All will have both red and white flowers.

Elephants exhibit herding behavior. When they travel, the oldest and largest members often travel in the outer edges of the group. Why is this important to the survival of the species
Answer:
Elephants do not have many offspring, therefore they need to protect them from predators, by the older and larger members of the herd travelling on the outer edges, the young are more protected from being hunted by predators. This is not a means to enhance mating or about food, it is also not just a mere method of organizing themselves either; by travelling this way they protect the survival of the herd and species as a whole.
Explanation:
This biomolecule is typically used as a source of energy for cellular respiration.
Answer:
The correct answer is "glucose".
Explanation:
Cellular respiration is the pathway of chemical reactions at which glucose is broken down to produce energy. In cellular respiration oxygen is used to broke down glucose, resulting in the production of carbon dioxide and water as by-products. The final objective of cellular respiration is to produce energy in the form of adenosine triphosphate (ATP). Therefore, the biomolecule that is typically used as source of energy for cellular respiration is glucose, and ATP is the molecule used to carry energy.

Jill has a headache and takes pain reliever to end the pain. This is an example of a(n):
Final answer:
Jill taking a pain reliever for her headache exemplifies conditioned behavior and the use of over-the-counter medication, highlighting a learned response to discomfort that's reinforced by the relief it provides.
Explanation:
Jill has a headache and takes pain reliever to end the pain. This is an example of a(n): conditioned behavior and use of over-the-counter (OTC) medication. When individuals take pain relievers, such as acetaminophen or non-steroidal anti-inflammatory drugs (NSAIDs) to alleviate pain, they are exhibiting a learned response to dealing with discomfort. This behavior is reinforced over time as pain relief follows the act of taking the medication, making it likely that they will turn to pain relievers again in the future. OTC medicines like aspirin, naproxen, and ibuprofen are commonly used for minor aches and pains associated with conditions like headaches, demonstrating a direct action on the pain pathway to alleviate symptoms. This practice is not only about the chemical effect of the medication but also involves psychological elements, such as the expectation of pain relief, which can enhance the overall effect.
How does a diversity of organisms increase the chances that some will survive a major change in environment ?
This can be explained with an example.
Let’s lake an example of two species 1 and 2.
Species 1 has a wide genetic diversity due to which organism are also diverse in phenotype. Their phenotype are:
Black, dark brown, brown, dark red, red, light red, pink, skin color.
From left to right organism are becoming less adapted to high temperature relatively.
For species 2: This species has less genetic diversity and its phenotypic diversity is as follow:
Black, red, Skin color.
From left to right organism are becoming less adapted to high temperature relatively.
Now if there is the sudden high temperature in the environment; 4 Types of phenotype will survive are black, dark brown, brown, dark red.
While there will only two types of organism in specie 2 which will survive are black, red.
So that’s how the diversity of organisms increase the chances that some will survive a major change in environment.
HALP MEH ASAP! Explain how energy moves through a food chain and a food web.
A food chain describes how energy and nutrients move through an ecosystem. At the basic level there are plants that produce the energy, then it moves up to higher-level organisms like herbivores. After that when carnivores eat the herbivores, energy is transferred from one to the other.
The epidermis protects deeper tissues from solar radiation through the action of ____________ .
The epidermis protects deeper tissues from solar radiation through the action of melanocytes.
Melanocytes are specialized skin cells situated in certain parts of the body such as the lower layer of the skin's epidermis, the inner ear, the middle layer of the eye, heart, and bones. Melanocytes are responsible for the production of the protective skin-darkening pigment known as melanin that determines the skin’s colour. Melanin mainly functions as protection against solar radiation. It also play a role in the immune system.

Extensive research along the Gulf Shore has uncovered a rise in cancer rates directly linked to consumption of seafood contaminated by the Deepwater Horizon blowout. How are the pro-drilling and anti-drilling arguments affected by this discovery? A) It supports the pro-drilling argument. B) It supports the anti-drilling argument. C) It is impossible to say how this evidence will impact either argument. D) It weakens the anti-drilling argument and weakens the pro-drilling argument.
The correct answer is option (B) It supports the anti-drilling argument.
Deepwater drilling refers to the process of drilling holes in the deep sea, below the seabeds for the purpose of mining petroleum compounds. Deepwater horizon blowout was an explosion causing a huge oil offshore oilspill in the Gulf of Mexico, making it the largest accidental marine oil spill disaster in the world. It has a numerous negative effects on the marine life.
The toxic oil and its compounds released into the water during the deepwater horizon blowout has contaminated the water and affected the marine life including the phytoplanktons, zooplanktons, invertebrates, fishes and other mammals of the sea. Highly toxic chemical components such as benzene and polycyclic aromatic compounds have even caused DNA damage and mutations in the marine life. Apart from their mortality, it has also been responsible for reduced growth, diseases, impaired reproduction in the sea fauna. Thus, ingestion of such contaminated seafood grown in contaminated water can be held responsible for the rise in cancer rates. Thereby supporting the anti-drilling arguement.
Answer: It supports the anti-drilling argument

A planet is orbiting a nearby star. Suppose that the star’s gravity increases over time. What effect will this increase most likely have on the planet’s path of motion?
A.
The planet will continue to move in an elliptical orbit around the star.
B.
The planet will begin to orbit the star at a constant speed.
C.
The shape of the planet’s orbit will change from elliptical to circular.
D.
The planet’s orbital path will become smaller and its orbital period will increase.
E.
The planet will begin to orbit the star in the opposite direction.
D. The planet's orbital path will become smaller and its orbital period will increase.
The more gravity an object has, the more it will pull objects.
Answer:
The correct answer will be option D.
Explanation:
Planets orbit around the Sun (star) due to the gravity of this star which pulls down them around it. This gravity is the vital force which maintains the elliptical path of their orbit.
If this force of gravity will change it will affect the celestial bodies revolving around it like a planet as this force of gravity is directly proportional to mass and inversely proportional to the distance between them.
According to the question if the gravity of the star increases it will change the orbital path of the planets as they will be more pulled towards the sun which will decrease the distance between the star and planet and the orbital path will become smaller and the orbital period will increase.
Thus, option D is the correct answer.
what are inputs and outputs of cellular desperation and photosynthesis?
While observing a cell under your microscope, you determine that it is a prokaryote. What about that cell made you think that? The cell lacks DNA. The cell lacks cytoplasm. The cell lacks a nucleus. The cell lacks a cell membrane.
The cell lacks a nucleus. We know this because prokaryotes are single celled organisms that lack a membrane bound nucleus or membrane bound organelles. So, looking under the microscope, you'd notice that the cell has no distinct nucleus, which immediately helps us find the answer we're looking for.

How does a cell separate itself from its environment and still allow materials to leave and enter the cell in order to maintain homeostasis?
ah! All thanks to the cell membrane!
The cell membrane contains phospholipids that are amphiphilic (polar - water attracting and non-polar - water repelling) in nature. That's why the cell membrane allows non-polar materials to pass through but not polar materials. (if you're learning junior science you really don't need to know this!) The polar materials require proteins found on the cell membrane called protein channels or carrier proteins to pass through. (their names are pretty self-explanatory!)
All the best!
