Four types of evidence for evolution are listed as follows:
1. The evolution of older species as seen in the fossil record.
2. the shared chemistry and anatomy of related biological species.
3. the geographical distribution of species that are linked.
4. the genetic alterations that have been observed in living things over many generations.
Organisms undergo gradual change over long periods of time by descent with modification. This transformation results from the organism's adaptation to its changing surroundings, climatic circumstances, style of life, etc. We can support the theory of evolution with some evidence. The following are the primary examples that bolster the theory: The structure of an organism has changed with time and is no longer the same as it was in the past, according to fossil evidence. According to evidence from embryology, different species that are descended from the same evolutionary ancestor share structural characteristics. In all earthly living organisms, the evolution of their basic chemical compositions and anatomical structures is fundamentally the same. No matter how complex the creature, whether they are tiny single-celled protozoa or incredibly complex organisms with billions of cells, they all begin as single cells and reproduce themselves by similar division methods (click this button to hear the term before it is pronounced). They all have a limited lifespan, get old, and die. Another cue concerning earlier evolutionary processes comes from the regional natural distribution of closely related species. It is clear that isolated, vast land masses and groups of islands commonly established their own distinct plant and animal species.

Biomes are areas with distinct climates and distinct ecosystems, characterized by certain plants and animals. The biological diversity of a biome is determined by the number and variety of organisms found there.
The following sets of biomes are placed in order from most to least biologically diverse:
Tropical Rainforest - This biome is characterized by a warm and wet climate, and is home to a wide variety of plants and animals. The dense forests and high humidity make this biome the most biologically diverse of the sets listed.
Temperate Seasonal Forest - These forests typically have four distinct seasons and are home to a wide variety of animals and plants, though not as varied as the tropical rainforest.
Woodland/Shrubland - This biome is characterized by shrubby vegetation and temperate climates. While there is a wide variety of plants and animals found in this biome, it is not as biologically diverse as the other biomes listed.
Subtropical Desert - This biome is characterized by hot, dry climates and sparse vegetation. There are a few species of plants and animals that can survive in this environment, but overall there is less biological diversity than in the other biomes.
Tundra - This biome is characterized by cold climates and low levels of vegetation. Few species of plants and animals can survive in this environment, and so it is the least biologically diverse of the sets listed.

How is most ATP formed during respiration?
Most of the ATP produced by aerobic cellular respiration is made by oxidative phosphorylation
Oxidative phosphorylation is responsible for the majority of the ATP generated by aerobic cellular respiration. Protons are pumped through a membrane to produce a chemiosmotic potential using the energy released. Then, ATP synthase is engaged by this potential to synthesis ATP from ADP and a phosphate group. During aerobic respiration, glucose and oxygen combine to produce ATP, which the cell can utilise. As products, water and carbon dioxide are produced. In the general equation for aerobic cellular respiration, glucose and oxygen combine to create ATP. Oxidative phosphorylation is the biochemical cycle that generates a most net ATP per molecule of glucose. The majority of ATP synthesis takes place during cellular respiration in the mitochondrial matrix, producing about 32 ATP molecules for every glucose molecule.

Compare and contrast the properties of oceanic crust and continental crust
Oceanic crust is generally younger than continental crust, being less than 200 million years old. It is made of basaltic rock, which is denser and more mafic than the granitic rock found in continental crust. Oceanic crust is thinner and more dense than continental crust, with average thickness of about 6 kilometers compared to about 35 kilometers for continental crust. Oceanic crust is also less buoyant and more prone to subduction.
Continental crust is generally thicker and less dense than oceanic crust, and is composed mainly of granitic rock. It is much older than oceanic crust, having formed over billions of years, and is also more buoyant due to its lower density. Continental crust is less prone to subduction and therefore is more likely to form mountains and landforms. It is also much thicker, with an average thickness of about 35 kilometers.

B. can support many different species.
C. usually only supports insect life.
D. supports animal life but not plant life.

Answer:
B. Can support many different species.
Explanation:
A niche is a position or role that a species plays in its ecological community or ecosystem.
If an ecosystem offers many different niches, this means that many different species can have a role in an ecosystem.
An ecosystem with many different niches will have a greater biodiversity and will also be more stable.
So, the correct answer is B. Can support many different species.

Plz help! In a density-dependent population, a decrease in which of the following will most likely cause an increase in birthrate?
Carrying capacity
Death rate
Emigration
Immigration
plz don't put link or ill report
In a density-dependent population, a decrease in the death rate will most likely cause an increase in birthrate. It is because a lower death rate means that more individuals are surviving, which can lead to an increase in the number of individuals reproducing, ultimately resulting in a higher birthrate. The correct option is B.
What is a density-dependent population?As we know that a population's birthrate tends to increase if there is a decrease in death rate, which also results in a decrease in carrying capacity.
Also, a density-dependent population is a population where the death rate increases and birthrate decreases with increasing population density, and vice versa. So, a decrease in the death rate of a density-dependent population will most likely cause an increase in the birthrate.
A density-dependent population is a population where the death rate increases and birthrate decreases with increasing population density, and vice versa. A decrease in the death rate of a density-dependent population will most likely cause an increase in the birthrate.

The stomach is the only part of the alimentary canal with three muscular layers. The stomach need three layers of muscle for digestion through peristalsis.
The stomach is a part of the body that includes the entire abdominal cavity which consists of the digestive tract and accessory organs, the urinary system, and the spleen. There are three layers of muscles in the stomach, namely the outer longitudinal muscles, the middle circular muscles, and the inner oblique muscles which help in peristaltic events.
Peristalsis is a movement in the form of muscle contractions in the digestive tract that pushes and stirs food so that it is digested. Through peristalsis the stomach will break down food and absorb nutrients during the digestive process.
