The theory of evolution has changed over time. Initially, Lamarck believed that organisms developed traits in response to a changing environment to improve their chances of survival. Later Darwin proposed that organisms that already possessed traits suitable to a changing environment were more likely to survive and reproduce.
Which of the following does not explain why the theory of evolution has changed?
A. Lamarck’s theory was discarded when new scientific information became available.
B. Darwin collected empirical evidence to support that organisms with favorable traits survived and reproduced.
C. The theory of evolution became a scientific law after much debate and confirmation in the scientific community.
D. Other scientists such as Peter and Rosemary Grant have collected additional empirical evidence that supports Darwin’s findings.

What are the possible genotypes for fur in each of the two guinea pigs shown here?
Answers
Answer:
black guinea pig:
1. BB
2. Bb
white guinea pig
1. bb
Explanation:
The black guinea pig carries the dominant trait. The "B" represents dominant trait. the "b" is recessive. When a dominant trait (B) is present, it will always take over making the guinea pig have black fur regardless of if there's a recessive trait. In order to get the white fur, you will need two recessive traits (bb).
The genotypes of 2 guinea pigs, for 2 traits are represented as AABB and aabb. The guinea pigs are mated and the offspring eventually mate with each other.
What is the meaning of genotypes?
A genotype is a genetic arrangement that makes up the traits that an organism inherited from its parents. Genotype can also mean the entire collection of genes an offspring inherited from its parents. In animals, a material known as DNA acts as the instructions that tell cells what to do.
What's a genotype ratio?
The genotypic ratio is the ratio depicting the different genotypes of the offspring from a test cross. It represents the pattern of offspring distribution according to genotype, which is the genetic constitution determining the phenotype of an organism.

List 5 types of as3xual reproduction and give an example of an organism that uses each type.
Answers
The different types of as3xual reproduction are binary fission, budding, vegetative propagation, spore formation (sporogenesis), The following are examples of as3xual reproduction in unicellular organisms:Binary Fission - In binary fission, the parent cell divides into two equal halves called daughter cells, either transversely or longitudinally. Amoeba, for example, divides transversely, but Leishmania divides longitudinally.Several Fission - A parent cell divides into multiple daughter cells at the same time in multiple fission. Sporozoans, for example.Budding occurs when organisms create a bud on the surface of their body, which eventually develops into a distinct person. For instance, Budding Yeast.

explain the difference between gills and lungs. Give examples of animals that have only gills, animals that have only lungs, and animals that have both gills and lungs. What are the advantages of having gills, having lungs, and having both?
Answers
Answer:
Gills and lungs differentiate in many ways most certainly when it comes to breathing. Gills are used by aquatic animals such as; sharks, fish and octopi. Lungs on the other hand are mainly used by mammals such as; humans, dogs and hamsters.
Lungs help breathe in air for oxygen and gills help breath in the oxygen contained in the water.
There's many advantages you could have with breathing through gills and lungs, you could swim under water for much longer periods of time and you could obviously walk on land and easily breath the air.
Sorry this took so long to write, I do hope this helped!
Good luck!
Lungs : are used to breath above water
Gills eg: fish
Lungs eg: human’s, lions etc
Animals that have both gills & lungs eg: frog , lungfish etc
Advantages are
Having lungs : can breathe on land
Having gills : can breath in water
Having both : can breath on land and in water

How does a frog embryo compare with a human embryo?
Answers
Answer:
bec its organs are have some of the organs that humans have example like a mouse or a rat
Explanation:
It is crucial to remember that these are merely broad generalisations and that different species and even different embryos can exhibit different specific processes and traits.
Human and frog embryos are similar and different in certain ways. These comparisons are provided: Size: Compared to human embryos, frog embryos are substantially smaller. Frog embryos grow to their full size in a few of weeks, but human embryos expand significantly over the course of nine months. Developmental phases: The stages of gastrulation, neurulation, and organogenesis are shared by frog and human embryos. The precise timing and information can change, though. Internal vs. external development: Human embryos develop internally in the uterus of the mother, whereas frog embryos externally develop in a watery environment.
