Comparing the skeletons of different animals provides compelling evidence that supports the scientific theory of evolution. By examining the anatomical structures and bone arrangements of various species.
Scientists can identify patterns that reflect common ancestry and gradual change over time. One way skeletons provide evidence for evolution is through the presence of homologous structures. Homologous structures are similar in form but may serve different functions in different organisms.
For instance, the pentadactyl limb structure, characterized by five digits, is found in a variety of vertebrates, including humans, bats, whales, and birds. This similarity suggests a common ancestor with a limb structure that has been modified for different purposes.

The model illustrates the relationship between photosynthesis and aerobic cellular respiration. Write balanced chemical equations showing the relationship between the two processes.
The balanced chemical equation showing the relationship between photosynthesis and aerobic respiration are
\(6H_{2}0 + 6CO_{2}\) + sunlight ⇒ \(6O_{2}+C_{6} H_{12}O_{6}\)
\(6O_{2} + C_{6} H_{12}O_{6}\) ⇒ \(6CO_{2} +6H_{2}O\) + ATP
Photosynthesis аnd cellulаr respirаtion аre connected through аn importаnt relаtionship. Photosynthesis mаkes the glucose thаt is used in cellulаr respirаtion to mаke АTP. The glucose is then turned bаck into cаrbon dioxide, which is used in photosynthesis. While wаter is broken down to form oxygen during photosynthesis, in cellulаr respirаtion oxygen is combined with hydrogen to form wаter. While photosynthesis requires cаrbon dioxide аnd releаses oxygen, cellulаr respirаtion requires oxygen аnd releаses cаrbon dioxide. It is the releаsed oxygen thаt is used by us аnd most other orgаnisms for cellulаr respirаtion.
We breаthe in thаt oxygen, which is cаrried through our blood to аll our cells. In our cells, oxygen аllows cellulаr respirаtion to proceed. Cellulаr respirаtion works best in the presence of oxygen. Without oxygen, much less АTP would be produced.

middle which diagram shows the changes in appearance of a plant cell when a remains in a concentrated sugar solution for thirty minutes? what is th answer
The osmosis diagram is the one that most accurately represents how a plant cell might change in appearance after spending thirty minutes in a concentrated sugar solution.
Osmosis is the process by which water molecules move from an area with a lower concentration of solutes to an area with a higher concentration of solutes across a semi-permeable membrane.
If a concentrated sugar solution were present, the solute concentration outside the plant cell would be higher than that inside.
Water from inside the plant cell would naturally try to exit the cell as it is submerged in the concentrated sugar solution in an effort to balance the solute concentration on either side of the cell membrane.

which disease is caused when there isn't enough bile to breakdown fat and oil in food . And how is it caused
Exocrine pancreatic insufficiency (EPI) causes problems in how you digest food. Your pancreas doesn't make enough of the enzymes that your body needs to break down and absorb nutrients. Enzymes speed up chemical reactions in your body. The enzymes made by your pancreas move into your small intestine, where they help break down the food you eat. When you have EPI, you don't get the nutrition you need because your body can't absorb fats and some vitamins and minerals from foods. You might lose weight or have pain in your belly.

question from which structure does a flatworm expel solid waste? responses pores in skin pores in skin vesicle
The structure from which a flatworm expels solid waste is through specialized excretory organs called protonephridia.
Flatworms, belonging to the phylum Platyhelminthes, possess a simple body plan with no specialized circulatory or respiratory systems. Instead, they rely on diffusion for the exchange of gases and nutrients. Protonephridia are networks of tubules that are spread throughout the flatworm's body. These tubules are equipped with flame cells, which have cilia that help filter waste materials from the surrounding tissues. The waste materials are then transported through the tubules, combined with excess water, and expelled from the body through excretory pores in the flatworm's skin.
It is important to note that flatworms do not have a separate system for expelling solid waste like more complex organisms. Their protonephridia system manages both waste filtration and excretion, ensuring that their body remains free from harmful substances. Additionally, flatworms have a gastrovascular cavity that serves both as a digestive and circulatory system, further emphasizing their simple yet efficient body plan.

In a population of 1000 individuals, 500 new individuals were born and 200 individuals died over the course of 1 year. Which equation show how to calculate the population growth rate of this population ?
Growth rate of population is 0.50 + 0.20 = 0.70.
How to calculate growth rate of population?(Initial individuals + newborn individuals) - dead individuals = total individuals
Growth rate = (total individuals/initial individuals) * 100
Population growth rate = new percentage minus 100%
Calculations
(1000 + 500) - 200 = 1500 - 200 = 1300
Growth rate = (1300/ 1000) * 100
= 1.3 * 100

what were two ways that earthworms display segmentation?
Earthworms display segmentation in two main ways:
External segmentation: The body of an earthworm is divided into a series of external segments, or metameres, that run the length of its body. Each segment is separated from the adjacent ones by a septum, which is a thin wall of tissue.
The external segmentation is visible on the surface of the earthworm's body as a series of rings or ridges.
Internal segmentation: Earthworms also display internal segmentation, with each segment containing a repeating set of organs and structures.
For example, each segment contains a pair of nephridia, which are excretory organs, and a set of circular and longitudinal muscles.
The digestive system of earthworms is also segmented, with each segment containing a portion of the intestine and associated structures such as the crop and gizzard.
These two types of segmentation are closely related and work together to allow earthworms to move and perform essential functions such as digestion and excretion.
The segmentation of earthworms is one of the key characteristics that distinguishes them from other types of annelid worms.
