describe with specific evidence from the chart how the fossil record and anatomy of horses supports the idea of evolution.
Answers
The fossil record and anatomy of horses provide strong evidence for the idea of evolution. The fossil record shows a clear pattern of change and adaptation in the anatomy of horses over time.
One example is the shift in the number of toes on the feet of horses. Fossils of early horses, such as Eohippus, show that they had multiple toes on their feet, while modern horses have only one toe on each foot. This shift in the number of toes is a clear example of the gradual adaptation of horses over time.
Anatomy also supports the idea of evolution in horses. For example, the anatomy of the jaw, teeth, and skull of horses has changed over time to accommodate their changing diets.
Fossils of early horses, such as Eohippus, show that they had small teeth and jaws adapted for eating leaves and soft vegetation. In contrast, fossils of later horses, such as Equus, show that they had larger teeth and jaws adapted for eating tough grasses.

Explain how sample size can affect the results of an experiment in genetics.
A phenotypic ratio for a dihybrid cross is predicted to be 9:3:3:1. The experimental values are purple smooth = 75, white smooth = 28, purple wrinkled = 24, white wrinkled = 8.
Answers
Small sample sizes may lead to deviations from the expected proportion rate of 9 3 3 1, it is for that reason it is fundamental to work with high N samples in genetics.
Why is important the N number sample in genetics?The number of samples or N number sample is fundamental in genetics because small samples may lead to statistical deviations to the expected frequencies that will be associated with a phenotypic ratio in particular, such as in this case white smooth = 28 and purple wrinkled = 24, when both numbers should represent the presence of a dominant character in a dihybrid cross.
Therefore, with this data, we can see that importance of the N number sample in genetics is major in the sense we need to obtain statistically significant differences to confirm a phenotypic ratio of 9 3 3 1.

Why are these "rules of thumb" sometimes unreliable?
Answers
Answer:
Rules of thumb are not scientific and do not take into account the individual circumstances and needs of a person, so they may not be applicable to your particular situation.
"Rules of thumb" are general guidelines or heuristics that people use to make quick decisions or judgments. While they can be helpful in many situations, they are sometimes unreliable for several reasons, such as limited or outdated information.
What are the rules of thumb?One of the reasons why rules of thumb can be unreliable is that they may be based on limited or outdated information. For example, a rule of thumb about the stock market that was popular in the 1980s may no longer apply due to changes in the market or economic conditions. Another reason why rules of thumb can be unreliable is that they may oversimplify complex situations. For instance, a rule of thumb about how to succeed in business that focuses solely on working hard may not take into account the importance of networking.
Hence, they are sometimes unreliable for several reasons, such as limited or outdated information.

Answers
Oogenesis is the process that originates the ovum, which is a much bigger cell than its counterpart, the sperm.
One ovum and two or three polar bodies are produced during this process. This is because the meiotic division is uneven and most of the cytoplasm goes to the future ovum, which means is able to have the resources needed to produce a new individual.
This means C) the cytoplasm and energy from the other 3 cells are placed into the mature egg and they do not have enough material to survive, is the right answer.

Answers
To answer this question we need to analyze each statement.
The members are geographically isolated from each other. This is not correct, because if each member is isolated there would be no reproduction and the population would be extinct in a generation period.
The members are reproductively isolated from each other. This is not correct as it would happen a very similar scenario depicted in the previous statement.
The members are genetically identical to each other. This is not correct as the majority of populations seek out outcrossing, this scenario occurs very rarely in some plants that self-pollinate however is not common.
The members are all of the same species. This statement is correct as populations are composed of organisms belonging to the same species, when we have several species or populations we are talking of communities.

-Between 23.5° north and 60° north
-Below 60° south and above 60° north
Answers
Answer:
Between 23.5° south and 23.5° north
Explanation:
The Tropical Forest biome has equatorial latitude therefore 23.5°N (the Tropic of Cancer) and 23.5°S (the Tropic of Capricorn) would be the answer because those are the mainly ranged locations of latitude.
Equatorial biomes are often found between 23.5° north and 23.5° south latitudes. Hence the correct option is B.
Equatorial biomes are characterized by their proximity to the equator, the imaginary line that divides the Earth into the Northern Hemisphere and the Southern Hemisphere. These biomes typically occur between 23.5° north and 23.5° south latitudes. It receives a high amount of direct sunlight and experiences little temperature fluctuation due to the Earth's axial tilt.
Within this range, we find diverse and lush equatorial biomes, such as tropical rainforests and tropical savannas. Tropical rainforests are known for their high biodiversity, with an abundance of plant and animal species, while tropical savannas are characterized by a mix of grassland and scattered trees and support a variety of wildlife.

Which of the following helps protect biofilms from issues such as drying out and predators
a.) Extracellular polymeric substances
b.) Quorum sensing
c.) Becoming sessile
d.) Autoinducers
Answers
Extracellular polymeric substances help protect biofilms from issues such as drying out and predators. Option A
Biofilms are complex communities of microorganisms that adhere to surfaces and form a protective matrix. They can be found in various natural and artificial environments, such as riverbeds, medical devices, and plumbing systems. Biofilms provide advantages to the microorganisms within them, including protection from environmental stresses and predators.
One of the key components that helps protect biofilms is extracellular polymeric substances (EPS). EPS are complex mixtures of polysaccharides, proteins, and DNA that are secreted by microorganisms within the biofilm. These substances form a matrix that encases the cells, providing structural support and protecting the community.
EPS help biofilms resist drying out by retaining water and preventing desiccation. The polysaccharides in EPS can absorb and retain moisture, creating a hydrated environment within the biofilm even in dry conditions. This is crucial for the survival of the microorganisms within the biofilm.
Additionally, EPS serve as a barrier against predators. The matrix formed by EPS can make it difficult for predators, such as protozoa or grazing organisms, to access and consume the microorganisms within the biofilm. It acts as a physical defense mechanism, limiting the exposure of the microorganisms to predation.
While quorum sensing, becoming sessile (immobile), and autoinducers are all important mechanisms and processes associated with biofilms, they do not directly address the protection of biofilms from drying out and predators. So Option A is correct.

Which statement summarizes a change that occurs during photosynthesis? It converts visible light to high-energy gamma rays. It converts carbon to oxygen. It converts light energy to chemical energy. It converts energy to mass.
Answers
Answer:
B) It converts carbon to oxygen
Explanation:
edge 2020
Because photosynthesis transforms light energy into chemical energy, which is then stored in the bonds of glucose, it is an energy-storing process. The correct answer is c) It converts light energy to chemical energy.
What is photosynthesis?Green plants and a few other species prepare their food through a process called photosynthesis, which involves sunlight, carbon dioxide, and water.
Plants, algae, and certain microorganisms employ the process of photosynthesis to transform light energy into chemical energy. The glucose produced during photosynthesis offers organisms two crucial resources: energy and fixed carbon.
Chloroplasts are unique organelles that are used for photosynthesis. This organelle can produce its own proteins since it has its own DNA and genes. The stroma, fluid, and stack of thylakoids known as the grana make up chloroplasts. Chlorophyll a, chlorophyll b, and carotenoids are three crucial pigments that are found in the chloroplast and absorb light energy.
Light enters the cell through the chloroplast during the photosynthesis process. Chlorophyll molecules on the granal stacks catch the light energy. Chemical energy is created in part from light energy. To create ATP, phosphate is added to a molecule throughout this process.
Hence, the correct answer is c).
