Answer:
Claim: Various factors can tree frogs to change color, such as outdoor temperature, brightness of light and moistness of the air.
Evidence: According to the National Wildlife Foundation "Tree frogs can be a variety of colors, but most of the species found in the United States are green, gray, or brown. Some of them, like the squirrel tree frog (Hyla squirella), are chameleon-like in their ability to change color."
Reasoning: Other factors can cause the variation of colors in tree frogs, these can be used as defense mechanisms to protect or camouflage themselves among their surroundings

If a hot liquid is poured into a cup, the cup will soon feel warm. How does the increase in temperature change the particles that make up the cup?
Answer:
Adding energy (heating) atoms and molecules increases their motion, resulting in an increase in temperature.
Removing energy (cooling) atoms and molecules decreases their motion, resulting in a decrease in temperature.
Energy can be added or removed from a substance through a process called conduction.
In conduction, faster-moving molecules contact slower-moving molecules and transfer energy to them.
During conduction the slower-moving molecules speed up and the faster-moving molecules slow down.
Temperature is a measure of the average kinetic energy of the atoms or molecules of a substance.
Heat is the transfer of energy from a substance at a higher temperature to a substance at a lower temperature.
Some materials are better conductors of heat than others.

Answer:
variation can be caused by mutation and other things
Explanation:
A mutation is a change that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light or cigerette smoke
➜ Following are the causes of variations:
Dual percentage: Offsprings inherit some features from mother and some from father. Hence no offspring will exactly resemble to either of the parent or each other.Mutation in gene or chromosomal pattern also causes variations.Please help me!!!!!!!!!!!!

The immune response consists of different components playing their role for a common goal: to rid the body of a pathogen. Create an analogy that helps explain the roles of the responses of the immune system and describe the relationship between the responses.
Answer:
In a primary immune response, naive B cells are stimulated by antigen, become activated, and differentiate into antibody-secreting cells that produce antibodies specific for the eliciting antigen.
A secondary immune response is elicited when the same antigen stimulates memory B cells, leading to the production of greater quantities of specific antibodies that are produced in the primary response
Answer:
In a primary immune response, naïve B cells are stimulated by antigen, become activated, and differentiate into antibody-secreting cells that produce antibodies specific for the eliciting antigen.

Human Immunodeficiency Virus (HIV) is a virus that infects (and destroys) Helper T Cells. As a result, people who are HIV+ generally have a low number of these T Cells. How would the dramatic decrease in Helper T Cells caused by HIV affect a person’s immune response? Be specific using details from what you learned about the immune response.
Answer:
HIV invades various immune cells (e.g., CD4+ T cells and monocytes) resulting in a decline in CD4+ T cell numbers below the critical level, and loss of cell-mediated immunity − therefore, the body becomes progressively more susceptible to opportunistic infections and cancer.
HIV infects and deletes CD4+ T cells that normally coordinate the adaptive T- and B-cell response to defend against intracellular pathogens. The immune defect is immediate and profound: At the time of acute infection with an AIDS virus, typically more than half of the gut-associated CD4+ T cells are depleted, leaving a damaged immune system to contend with a life-long infection.

What determines the potential energy of particles in matter?
Complete the chart. Thymine _____, Guanine ____.
Answer: 27, 23
Explanation: Thymine goes with Adenine and together they equal 50 so Thymine would be 27 because Adenine is 23. Same with Cytosine and Guanine. They go together and equal 50 so Guanine would be 23 because Cytosine is 27. Hope this helps!

Answer:
1) As soon as the paper cuts into the cells of your skin, your body springs into action. First, blood cells called platelets join together at the paper cut and form a clot to stop the bleeding.
The process is called Blood clotting.
2) The cell that are made will have the same same amount of DNA/chromosomes.
3) Chromosomes come in pairs. Normally, each cell in the human body has 23 pairs of chromosomes (46 total chromosomes). Half come from the mother; the other half come from the father. Two of the chromosomes (the X and the Y chromosome) determine your sex as male or female when you are born.

Which cell replicates via meiosis?(1 point)
sperm cell
heart cell
skin cell
red blood cell
thanks!!
Answer:
Sperm cell
Explanation:
Because it is a reproductive cell and in one of the stages of foetus growth is meiosis so this cell undergoes meiosis to pass that stage
Meiosis is the process by which cells divide into four haploid daughter cells.Sperms are the cells that replicates via meiosis. Option A is correct.
Meiosis:
It is the process by which cells divide into four haploid daughter cells.
The daughter cells contains half of its parents chromosomes.The daughter cells are genetically different from the parent cells.It is occur in the germ cells of the organisms to produce gametes like sperm and ovum.Therefore, sperms are the cells that replicates via meiosis.

Starting on bare rock what is the usual ecological succession of organisms
Complete question:
Starting on bare rock, what is the usual ecological succession of organisms?
a)shrubs--grasses--lichens--trees
b)lichens--shrubs--grasses--trees
c)grasses--shrubs--lichens--trees
d)liches--grasses--shrubs--trees
Answer:
d)liches--grasses--shrubs--trees
Explanation:
The succession is the colonization of an open area and includes all the changes the area suffers since then. It is a sequence of events that involves the establishment of different species through time.
There are two types of succession, primary and secondary, depending on the magnitude of the alteration.
Primary succession refers to an open space with no living organisms, such as a bare rock exposed due to a retreating glacier, a volcanic activity, or an intense fire. If previous species were inhabiting this area, after the event, nothing is left.
In those cases where there is an alteration or disturbance at a site that opens the area, it allows new species to grow. With time, new species arrive and manage to establish again. The order of the establishment depends on the strategies of each of the species to survive.
First, pioneer species arrive. These are the first inhabitants, mostly lichens or moses with the capability of surviving in such an environment. Only a few pioneers can establish in the open space. Pioneers modify the habitat. They make it more suitable for the establishment of later species, converting rock into fertile soil. As conditions get better, new species arrive like grasses. Grasses and pioneers keep modifying the soil, making it better with time. New species arrive, like small species, bushes and shrubs. Habitat modification keeps on going while new species establish (trees, pines, among other big species). They produce shadows, alter the temperature, and humidity, fertilizing the soil, competing for resources. Competition becomes more frequent between species. The first species are eventually eliminated by competition, but new species keep appearing and competing for resources. This sequence continues until the commuting reaches a climax, becoming stable and lasting for hundreds of years until another disturbance occurs.
Answer:
D. liches--grasses--shrubs--trees
Explanation:
primary ecological succession will be as: lichens inhabit bare rocks and breakdown the minerals rich material in the rock and die to produce organic material so that new species could be formed as grasses will grow which will become shrub and eventually the tree. Animals eat those grass, shrub or tree products.
A group of mice becomes separated by the formation of a river. Over time, the northern mice became smaller and whiter, while the southern mice became larger and browner. This is an example of:
Answer Choices:
-divergence
-homology
-gigantification
-industrial melanism
This is an example of gigantification.
What is meant by evolution?
Evolution is the change in the features of a species over several generations and depends on the procedure of natural selection. The theory of evolution is based on the idea that all species are related and gradually change over time.
Thus, this is an example of gigantification.
