What is the difference between a specialized plant cell and a specialized animal cell?
Answer:
Explanation:
Major structural differences between a plant and an animal cell include: Plant cells have a cell wall, but animals cells do not. Chloroplasts enable plants to perform photosynthesis to make food. Plant cells usually have one or more large vacuole(s), while animal cells have smaller vacuoles if any are present.
1. Which layer is the oldest? Which layer is the youngest? How do you know?
2. What are some characteristics of the organisms in layers 1-6?
3. What are some characteristics of the organisms in layers 7-12?
4. Develop a theory as to how the organisms in this area changed over time.
Answer:
the youngest layer is 7(middle point) because decomposition must occur in the middle of decomposed materials.the oldest is 12(upper one) because decomposed material are found at the top most of organisms.they are highly decomposed material.they don't decompose easilyThe youngest layer is 7(middle point) because decomposition must occur in the middle of decomposed materials. The oldest is 12(upper one) because decomposed material are found at the top most of organisms. They are highly decomposed material. They don't decompose easily.
What is Decomposition?Decomposition of organic matter is a complex process that involves the breakdown of complex molecules into simpler ones by the action of microorganisms. In the case of the layers mentioned, the higher layers are the oldest because the decomposed material is found at the top of the layer, and it takes a long time for the organic matter to decompose into soil.
The highly decomposed material in these layers is called humus. Humus is a dark brown or black organic substance that is a result of the decomposition of plant and animal matter. It is an essential component of healthy soil as it provides nutrients to plants and helps retain moisture in the soil.
Humus does not decompose easily because it is a stable form of organic matter. It is made up of complex molecules that are resistant to further decomposition. This makes it an important component of soil fertility as it can remain in the soil for hundreds of years, providing a steady source of nutrients for plants.
Overall, the highly decomposed material found in these layers is an important indicator of the age and health of the soil. Understanding the decomposition process and the factors that affect it can help us better manage our soil resources for agriculture, forestry, and other uses.

Answer:
Evolution means change in the physical features of an organism.
Explanation:
Evolution means change in the physical features of an organism. Evolution occurs in the population of an organisms due to various factors such as mutation, non-random mating and natural selection. Nonrandom mating occurs when an organism prefer mating with particular superior organisms or with the similar organism. Mutation in the genetic makeup of an organism is also responsible evolution. this mutation occurs when an organism experience ultraviolet radiation from the sun, or also occur if an error in DNA during cell division. Gene flow is also known as gene migration is the transfer of genetic material or traits from one population to another when the organism is migrated to another environment. Some organisms are selected naturally because they have the potential to survive in that environment so they survive and that doesn't adopt itself to the environment, it will extinct from the environment.

Within a population of rabbits, black fur (B) is dominant over white fur (b). A scientist observes 16% white rabbits on an island. The dominant allele frequency of this population is
Answer:
Explanation:
According to hardyweinberg principle
p+q= 1
P2+2pq+q2=1
given that
Black fur =B =p(dominant allele)
White fur =b =q (recessive allele)
q2=16%
16/100=0.16
q=√0.16
q=0.4
Since p+q=1
P=1-q
P=1-0.4
P=0.6
Therefore the allele frequency for dominant organism Black fur is 0.6

archaea are more or less similar to eukaryotes than bacteria
Answer:
Although archaea superficially resemble bacteria in terms of size and cellular organization (members of both groups lack nuclei), they are surprisingly similar to eukaryotes at the molecular level. For instance, all archaea replicate their DNA and synthesize proteins using molecular machines like those of eukaryotes.

Answer:
0%
Explanation:
Let's use a Punnett square to solve this problem.
A B
O AO BO
O AO BO
The Punnett square shows that 50% of their children will have the AO genotype and 50% will have the BO genotype. Neither of these genotypes give the child type O blood, so it is impossible for the child to have type O blood. The child would need two O alleles.

Chromosomes, genes, DNA are different names for different parts of ______________ thing. (I don't understand this???)
Answer:
of the same thing
Explanation:
Deoxyribonucleic acid (DNA) is the molecule that contains the hereditary genetic material in humans and almost all other organisms. Moreover, chromosomes are thread-like structures composed of DNA that contain part or all of the genetic material of a particular organism. Finally, genes are chromosome segments that contain the information needed to synthesize an RNA molecule by the process of transcription, typically a messenger RNA (mRNA) molecule which is subsequently used to encode a protein sequence through the process of translation.

What is photosynthesis, and what is it's main goal?
Answer: Photosynthesis is the process of when a plant makes it's own food, and the main goal is to convert solar energy to chemical energy.
Explanation: Plants use photosynthesis by taking the sunlight, to synthesize foods from carbon dioxide and water. Since plants can't move and consume other organisms, they use photosynthesis. The formula is: [tex]6CO_2+6H_2O=C_6H_1_2O_6+6O_2[/tex].
Like I said, the main goal is converting solar energy to chemical energy then store the chemical energy for future use, for example it can be used for Chemical batteries, Natural gas, Heat, Food, etc.
A population of lizards carry a gene for scale color in which the dominant allele produces green scales while the recessive allele codes for brown scales. In the first generation, you determine that 75% of the population is green and 25% of the population is brown. In the second generation, you determine that 50% of the population is green and 50% of the population is brown. Finally, in the third generation, you determine that 25% of the population is green and 75% of the population is brown. Which of the following correctly explains this change in the genotype frequencies?(1 point)
The lizards mate randomly with each other.
The brown color is an adaptation that is being selected by the environment.
The lizards remain isolated from other lizards, only mating with lizards in their own population.
The DNA of these lizards carries no mutations from one generation to the next.
Answer:
1) There are no mutations in the DNA of the population.
2) The brown color is an adaptation that is being selected by the environment.
3) The number of individuals displaying each phenotype in both the current generation and the offspring.
4)The recessive phenotype in this population may serve as an adaptation in this environment.
5) A population of flies that maintains a population size of at least 1 million individuals.
Explanation:
just took the test (connexus student)
Correct answers are :
No mutations in the DNA.The brown color is an adaptation.individuals displaying current generation, offspring.Rcessive phenotype adaptation.Flies population has a size of at least 1 mn.What is a genotype?A genotype is a set of genetic material that characterize an organism and is also used or refer to the allies or the variant of that individual that carries genetic material.
The population of lizards has a gene for scale color that is a domain allele. The brown color is due to the adaptation of the species.
