Answer:
Biology is not a hard class however it does require memorization and comprehension of certain topics. I recommend that you read over the chapters and make flashcards and test yourself. You can also ask your teacher for help. There are many videos available that do a great job at explaining each topic in biology. In addition, there are various websites that can also provide information. You should make study groups with your classmates as it is a more fun and effective way of studying.
Answer:
Firstly, don't stress, you'll get through it. Worrying will just slow you down, and learn Biology as something you get to do, and not a chore.
And if you want to relearn everything from the beginning, then I would recommend Crash Course's free Biology courses on YT, they also have Chemistry courses and everything. You can also go to Ask a Biologist, where you can do more than just ask questions.
There are so many more sources of information and everything, but one thing is; don't stress, that's the key.
Good luck, stay safe and healthy.
You'll get through it! Don't worry. If you want me to recommend more websites to you, just comment on this answer :D

Explanation:
Classification-
The process of grouping things
based on similarities.
Taxonomy
The scientific study of how living
things are classified.
Aristotle-Was Credited with creating the first classification system around 5AD. And he only classified objects as plants or animals
Carolus Linnaeus was known as the Father of Taxonomy.And he Gave us the hierarchical system we now use.(His system had 3 Kingdoms)
- Animals
- Plants
- Mineral
**Sorry I don't know the answer to this question here(george fox and Carl worse....)**
The 8 levels of classification:
Broadest levels:
1.Domain
2.Kingdom
3.Phylum
4.Class
Most specific:
5.Order,
6.Family,
7.Genus,
8.Species
*Species is the most specific category of classification of organisms so as each group split into smaller groups the organisms are more specific.**
Domain is The highest rank of organisms in biological taxonomy. It divides all cellular life forms into three groups.
Archaea
Bacteria
Eukaryotes

Calculate phenotype frequencies in 5th generation. Record in Lab Data
Answer:
The number of moths in 5th generation (G5) with:
Typica phenotype (white) = 878
Carbonaria phenotype (black) = 54
total moths observed = 932
5th generation Phenotype frequency:
f (Typica) = Number of Typica phenotype in G5/ total moths in 5th gen
f (Typica) = 878/ 932
= 0.94
f (Carbonaria) = Number Carbonaria phenotype in G5/ total moths in 5th gen
f (black) = 54/ 932
= 0.057
The phenotype frequency in the 5th generation is:
0.057According to the given question, we can see a table which contains the values of Environment, Phenotype Frequency and Allele Frequency and we are asked to calculate the phenotype frequency in the 5th generation.
As a result of this, we can see that we have to use the values of the Typica phenotype (white), the Carbonaria phenotype (black) and the total moths observed = 932 with the formula, Number of Typica phenotype/total moths in 5th gen.
With this in mind, we would get f (black) = 54/ 932 which would give us the value of 0.057
Therefore, the correct answer is 0.057

When comparing two species, the presence of which type of structures indicates descent through modification from a common ancestor
Answer:
Homologous characters indicate descent through modification from a common ancestor.
Explanation:
Homologous characters have the same fundamental structures. They also share the same relations with adjacent structures, and they have the same embryological development.
These structures might show variations between organisms exhibiting them, according to their function and to the environment in which the organism lives.
These homologous characters are common in organisms related and that share a common ancestor.
For example, whales, humans, and horses all have the same bones in the same order, but they matured differently in later embryological development. This is an example of homologous characters.
Homologous characters indicate descent through modification from a common ancestor.
and also by comparing the DNA of the two species. The more nitrogenous bases and amino acids two species have in common, the more closely related they are.
Which are the best examples of homologous structures?
An example of homologous structures is the forelimbs of vertebrates, where the wings of bats and birds, the arms of primates, the front flippers of whales and the forelegs of four-legged vertebrates like dogs and crocodiles are all derived from the same ancestral tetrapod structure.
Thus by examining the homologous structures one can determine.

The overall chemical equation that describes photosynthesis is shown below.
600, + 6H20 - CH12O6 + 60,
By analyzing this equation, which property of photosynthesis can be identified?
A the chemical changes that occur during the light independent reactions
B. the chemical changes that occur during the light dependent reactions
C. the source of carbon atoms in the carbohydrate product
D. the identities and roles of electron carriers
Answer:
A
Explanation:
Occur during light reaction process to manufacture food and release oxygen
.
The overall chemical equation that describes photosynthesis is the chemical changes that occur during the light independent reactions(option -A).
Why is the process of photosynthesis named that?Light energy is converted into chemical energy during photosynthesis by phototrophs, which is subsequently used to drive cellular functions. The form in which the chemical energy is stored is in the form of sugars, which are produced from water and carbon dioxide.
Photosynthesis' main job is to transform solar energy into chemical energy and then store that chemical energy for later use. The majority of the planet's biological systems are propelled by this process.
Anoxygenic and oxygenic photosynthesis are the two forms. The former is the more prevalent type, found in plants, algae, and cyanobacteria, and they both operate on very similar principles.

in an understanding of the molecules within cells and of the interactions between cells that allow construction of multicellular organisms. The more we learn about the structure, function, and development of different organisms, the more we recognize that all life processes exhibit remarkable similarities. Molecular Cell Biology concentrates on the macromolecules and reactions studied by biochemists, the processes described by cell biologists, and the gene control pathways identified by molecular biologists and geneticists. In this millennium, two gathering forces will reshape molecular cell biology: genomics, the complete DNA sequence of many organisms, and proteomics, a knowledge of all the possible shapes and functions that proteins employ.

The flame of many stove burners is blue, but the wires of a toaster glow orange. How do you think the temperatures of these two cooking appliances compare?
Answer:
the hotter is it, the more bluish it is. And the more reddish it is, the colder it is
just like the bluer the star, the hotter it is, the redder the star, the colder it is.
Comparing the temperatures of the two cooking appliances ; The temperature emitted in stove burners are hotter than the temperatures emitted by the toaster
White-Blue flames are the hottest flames when combined together but the hottest single flame is the blue flame burning between ( 2,600º F and 3,000º F). Blue flames have more oxygen than other types of flames, hence they burn hottest and this is because gases when burnt are hotter than other materials. while
The orange flame of a toaster burns at a temperature between ( 1100°C to 1200°C) . releasing carbon monoxide as it burns.
Hence we can conclude that The temperature emitted in stove burners are hotter than the temperatures emitted by the wires of a toaster.

Explain why hemoglobin is more suitable for carrying oxygen in the blood and myoglobin more adept at storing oxygen in the skeletal muscles.
Answer:
Because their structures are different, both are proteins but are shaped in space differently, causing hemoglobin to saturate at high partial pressures of oxygen, and yield oxygen to the medium, while myoglobin at high partial pressures of oxygen will taking.
Explanation:
Hemoglobin has a tetrahedral form, while myoglobin contains a triad form of three main components and not 4.
In addition, myoglobin must capture oxygen to oxygenate the muscle in muscle contraction, since this demands the presence of this gas and the energy currency that is called ATP.
