In a given year, which would result in the greatest increase in population size?
A. high birth rate, high death rate, high immigration, high emigration
B. high birth rate, zero death rate, high immigration, zero emigration
C. zero birth rate, low death rate, zero immigration, low emigration
D. zero birth rate, zero death rate, low immigration, high emigration
Answer:
B. High birth rate, zero death rate, high immigration, zero emigration
Explanation:
High birth rate would mean more people being born resulting in a higher population. Zero death rate would mean that no one is dying and leaving the population. Immigration means when people come to a foreign country to live there, meaning that the population would grow. Emigration means the opposite of immigration. So that would mean that the people would be leaving your country. Resulting in a lower population. So, B is the correct answer!

I don’t understand it, if someone can explain maybe what I have to do and put into each Column or give me the answer either way would help a lot. Thank you.
Answer:
First, describe each type of evidence (eg. Molecular biology is comparing DNA sequences to determine common ancestry). Then provide examples of how those pieces of evidence support the theory of evolution. For example, for one of the comparative anatomy examples, you could say that organisms that contain similar structures most likely diverged from a common ancestor.
I hope this gets you on the right track.

Biotic and abiotic factors affect population density and dispersion. A) Explain the factors that affect a population's density. B) Describe the types of population dispersion, with examples, and the factors that influence them.
Answer:
Water supply, climate, shape of the land, vegetation, soils and availability of natural resources.
Explanation:
Water supply, climate, shape of the land, vegetation, soils and availability of natural resources are the factors that affect population density of an ecosystem. There are three types of population dispersion are uniform dispersion, random dispersion, and clumped dispersion. In uniform dispersion, individuals of a population are more or less evenly distributed for example, allelopathy plants. In random dispersion, individuals are distributed randomly in the ecosystem for example, dandelions plants. Clumped dispersion is when individuals in a population are clustered together for example, oak trees.

3. How are frog eyes different from human eyes?
Answer:
Most frogs see well only at a distance, but they have excellent night vision and are very sensitive to movement.This peripheral vision helps them spot predators and prey. Humans and other mammals focus images by changing the shape of the lens. Like a camera lens, frog eyes focus by moving the lens back and forth.

Pietro has two dogs that are related, and he wants to understand why one of the dogs has tan fur and the other has brown fur.
Which pattern of inheritance would explain the different fur color in the related dogs?
polygenic inheritance
codominance
incomplete dominance
quantitative inheritance
Answer:
A
Explanation:
Just finished the quiz
Inheritance is defined as the transmission of genetic information from the parent to the offspring. The pattern of inheritance can be polygenic, incomplete, co-dominant, or quantitative.
The correct answer is:
Option A. polygenic inheritance
Polygenic inheritance is defined as the controlling of one trait by two or more genes. The phenotypic traits of an organism are influenced by one or more than one gene.
In the case of dog fur, the relative dogs have brown and tan fur that is due to polygenic inheritance. Thus, it determines the fur color of the dogs is controlled by more than one gene that can completely influence the phenotypic traits.
Therefore, the correct answer is polygenic inheritance.

1- How could you tell whether a given sequence was DNA or mRNA?
2- Was it easier to decode messages written in DNA or in mRNA sequences?
3- Which cellular enzymes or machines are you imitating when you "transcribe" DNA into mRNA?
4- Which cellular enzymes or machines are you imitating when you "translate" mRNA into a chain of amino acids?
5- What else needs to happen in a eukaryotic cell between the processes of transcription and translation?
6- In step 5, how did different mutations affect the amino acid sequence that was encoded?
7- Explain why some single nucleotide mutations affect an amino acid sequence and some single nucleotide mutations do not.
8- Explain why nucleotide insertions and deletions affect the amino acid sequence so profoundly.
9- Why could your secret message include only 20 of the 26 letters of the alphabet?
10- Did you find that it was difficult to work with only these letters?
Answer:
DNA sequences use the nucleotides A, T, G, and C, while mRNA sequences use the nucleotides A, U, G, and C.
It was easier to decode the messages written in mRNA sequences because these sequences could be translated directly into the amino acid sequence.
The cellular enzyme that carries out transcription is RNA polymerase.
The cellular machine that carries out translation is the ribosome, which is composed of both rRNA and ribosomal proteins.
In a eukaryotic cell, an mRNA transcript often has additional untranslated regions and a poly-A tail. A eukaryotic mRNA transcript would need to be transported from the nucleus to the cytoplasm before it could be translated.
Some amino acids are encoded by several codons. If a single nucleotide mutation still encodes for the same amino acid, the resulting amino acid sequence would not be affected. This happens most often with nucleotides in the third position of a codon.
If a single nucleotide mutation changes the amino acid encoded, the resulting amino acid sequence would be affected. This happens most often with nucleotides in the first and second positions of a codon.
Nucleotide insertions and deletions cause frameshift mutations, which change the reading frame of translation and will encode completely different amino acids from that point forward.
There are only 20 canonical amino acids, so the letters B, J, O, U, X, and Z are not used as one-letter codes.
It was a little difficult to not use the letters B, J, O, U, X, and Z at first, but there are messages to write without these six letters.

What kingdom is the Dandelion in?
animal
protist
fungus
plant
Answer:
D. Plant
Explanation:
Dandelion is a plant with yellow flowers. If the flower is a plant then it would be in the plant kingdom. Flowers aren't animals, nor protists. Protists are organisms that are part of the biological kingdom called the protista. These organisms are not plants, animals, bacteria, or fungi. Fungi (Fungus) are like mushrooms and other types of things like that who feed on dead organisms. Flowers don't feed on dead organisms. So that leaves the plant kingdom.

Where a disturbance did not completely wipe out all life and nutrients from the environment, secondary succession occurs and homozygous.
Thus, Despite the fact that fire, flooding, and other disturbances can leave a landscape in ruins, drive many animals and plants away, and bring the biological community back to an earlier stage, the habitat is still alive because the soil still contains nutrients and seeds that were sown before the disturbance.
The homozygous genotypes' two alleles are not expressed over one another in incomplete dominance; instead, an intermediate heterozygote is created.
A significant contributing factor to the variety in the traits or properties of an organism is incomplete dominance.
Thus, Where a disturbance did not completely wipe out all life and nutrients from the environment, secondary succession occurs and homozygous.

PLEASE MARK ME AS BRAINLIESTScientists who study biogeochemical cycles often use the term fixation to describe converting an element from gaseous form in the atmosphere to solid form in the biosphere. For example, in the nitrogen cycle, bacteria are said to fix nitrogen by converting N2 gas into nitrates and nitrites in the soil that are later used to make organic macromolecules such as proteins and nucleic acids. There are many processes involved in cycling carbon, but only one is able to fix carbon from its gaseous form in the atmosphere to solid form in the biosphere. Which process performs carbon fixation
Answer:
Photosynthesis
Explanation:
Carbon fixation refers to the process by which elemental carbon in gaseous form in the atmosphere is converted to a solid form in living organisms. It is part of the larger process known as the carbon cycle. The carbon cycle is a very important cycle which involves the different steps by which carbon is exchanged between living organisms and their environment. The carbon cyclemis divided into the biological carbon cycle and the biogeochenpmical carbon cycle. The biological carbon cycle is the rapid exchange of carbon among living things while the biogeochemical cycle refers to the much slower cycle by which carbon is stored and released from carbon reservoirs in the environment.
In nature, carbon fixation occurs in the process of photosynthesis. During photosynthesis, green plant ( autotrophs) in the presence of sunlight as an energy source uses carbon present in air as carbon dioxide together with water vapour to produce organic biomolecules known as simple sugars which are also stored as starch. The products of photosynthesis are then used by heterotrophs, to return carbon in the form of carbon dioxide back to atmosphere.

how the cells in your body are different from one another. Look at the different types of cells above, and make a list of how they differ. After you have made your list, consider why they have these differences.
Answer: Different cells have different jobs to do. Each cell has a size and shape that is suited to its job. Cells that do the same job combine together to form body tissue, such as muscle, skin, or bone tissue. Groups of different types of cells make up the organs in your body, such as your heart, liver, or lungs.Differentiation means that one cell performs a different function than another cell, depending on where it is in your body. ... All the cells contain the same genetic material and all of them are from one original cell that started as a fertilized egg, but they look different and act different from one another. Under a microscope, fat cells look like bulbous little spheres. Like other cells in the body, each has a cell membrane and a nucleus, but their bulk is made up of droplets of stored triglycerides, each of which consists of three fatty-acid molecules attached to a single glycerol molecule. Skin cells are specialized to be quickly shed and replaced, and do not have much mitochondria (which helps produce energy). Muscle cells, conversely, have lots of mitochondria because they need energy to produce movement. Unlike many other cells, red blood cells have no nucleus and can easily change shape, helping them fit through the various blood vessels in your body. Unlike most other eukaryotic cells, mature red blood cells don't have nuclei. When they enter the bloodstream for the first time, they eject their nuclei and organelles, so they can carry more hemoglobin, and thus, more oxygen. Each red blood cell has a life span of around 100–120 days. Skin cells are specialized to be quickly shed and replaced, and do not have much mitochondria (which helps produce energy). Muscle cells, conversely, have lots of mitochondria because they need energy to produce movement. brainliest??
