According to the food web shown above, what is the relationship between the wheat, the grasshopper, the frog, and the snake?
A. The snake directly consumes the frog, the grasshopper, and the wheat.
B. The grasshopper consumes the wheat, and the snake consumes the frog, but there is no connection between the other organisms.
C. The wheat is consumed by the grasshopper, the grasshopper is consumed by the frog, and the frog is consumed by the snake.
D. The wheat is directly consumed by both the grasshopper and the frog, and the frog and the grasshopper are directly consumed by the snake.
Answer:
The wheat is consumed by the grasshopper, the grasshopper is consumed by the frog, and the frog is consumed by the snake.
Explanation:
A food web is a model that can be used to better understand the feeding relationships between organisms in an ecosystem. Arrows in a food web start at a food source and end with the consumer.
So, in the food web shown in the question, the wheat is consumed by the grasshopper, the grasshopper is consumed by the frog, and the frog is consumed by the snake.

Bat wings, a human hand, and a whale flipper are all ________________structures. Explain WHY?
Butterfly wings and bat wings are examples of _______________ structures.
The mouths of horseflies and mosquitoes are examples of _______________ structures.
A _______________ structure is one that does not currently have a function in the organism. Give an example.
Comparing structures of embryos is an example of __________________.
If embryos share a common structure, what does that say about their evolutionary relationship?
How would the protein sequence of two closely related species compared to the protein sequences of two unrelated species? Give an example of each here.
Answers:
1.blank: Homologous
why?: They all have similar structures passed on from a common ancestor. Although they all have different functions now, they still all have the same basic pattern of bones.
2.blank: Analogous
why?: Butterflies and bats are both unrelated organisms but they both have similar structures. However, unlike homologous structures, analogous structures do the same job (help the organism fly) but are structured entirely differently because they evolved in the two species independently and did not share a common ancestor.
3.blank: Homologous
why?: (see question 1 ^)
4.blank: Vestigial
example: An example of a vestigial structure is a human's tail bone.
why?: Over time humans evolved and our tail bones shrank as we adapted. While we still have one, it serves no purpose in our lives today.
5.blank: Embryology
why?: Embryology is the branch of science and medicine that is focused on the development and study of embryos. Scientists in this field study the prenatal development of gametes, fertilization, and development of embryos and fetuses.
6.answer: They share a common ancestor
why?: Embryos of many different species can show evidence of sharing a common ancestor based on the similarities and structures of them all. Similar structures during development support common ancestry. For example, all vertebrae embryos develop gill slits and tails but not all develop into those structures. Over time as organisms evolved their structures changed with them.
7.answer: If the protein sequence of two species is closely related the two species are most likely similar, but the protein sequences of two unrelated species are not similar meaning these two species are very different. By comparing the positions of amino acids on protein chains you can determine how similar the species are. The less different the positions are, the more alike and related they are.
why?: For example, humans and chimpanzees only have one position on the amino acid chain where they are different but if you compare humans and moths there are 31 different positions.
I included some extra information in this for you so you hopefully can learn something too! I hope this helps and if you have any questions on what I put or anything else, let me know. :)

What is true about two different cell types in the body?
Answer:
Option B
Explanation:
In cell differentiation, the objective is to differentiate cells based on their functions and the organs they are going to form. In this exercise, the cells need to get on and off to define the type of the cell and its function. Hence options A, C is important for cell differentiation. Information from DNA is transferred to mRNA for cell differentiation; hence option D is also correct. While option B has no role in cell differentiation loss of DNA segment could cause mutation i.e. deletion.
Hence, option B is the correct answer
Which types of substances need energy and active transport
Answer:
Explanation:
Types of active transport include ion pumps, such as the sodium-potassium pump, and vesicle transport, which includes endocytosis and exocytosis. Cell transport helps cells maintain homeostasis by keeping conditions within normal ranges inside all of an organism's cells.
Glycolysis, or the breakdown of glucose, is a process used by almost all organisms as a way to release energy stored within glucose molecules. This energy can then be stored in cells as ATP, which powers cell processes when needed. What does this show, in terms of the evolutionary history of cells using glycolysis?
Answer:
It was one of the earliest metabolic pathways.
Explanation:
The evolutionary history of cells using glycolysis shows that It was one of the earliest metabolic pathways which is used by nearly all of the organisms on earth for the production of energy for the survival, growth and development. The first organisms used this pathway for the generation of energy and with the passage of time, new pathways are also formed as the organism evolved so we can conclude that glycolysis is the first pathway used by the earliest organisms.

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.

illustrate the cellular respiration pathway
Explanation:
Cellular respiration is a collection of three unique metabolic pathways: glycolysis, the citric acid cycle, and the electron transport chain. ... In order to move from glycolysis to the citric acid cycle, pyruvate molecules (the output of glycolysis) must be oxidized in a process called pyruvate oxidation.

Potassium-40 has a half-life of 1.3 billion years. If a rock was
determined to be around 3.9 billion years old what percentage
of the original potassium-40 would be left in that rock sample?
Answer: The 3.9 billion year old rock has undergone three half-lives (3.9 divided by 1.3 = 3). After 3 half-lives, 12.5% of the potassium-40 remains undecayed.

How do weathering and erosion work together to change or build landforms
Answer:
Erosion is another geological process that creates landforms. When mechanical and chemical weathering breaks up materials on the Earth's surface, erosion can move them to new locations. For example, wind, water or ice can create a valley by removing material. Plateaus can also be formed this way.

Answer:
Dna i think im not sure if it is right?
Explanation:
Answer:
HERC2 is a giant E3 ubiquitin protein ligase, implicated in DNA repair regulation, pigmentation and neurological disorders. It is encoded by a gene of the same name belonging to the HERC family, which typically encodes large protein products with C-terminal HECT domains and one or more RCC1-like (RLD) domains.
