Answer:To initiate an immune response and antibody production
Explanation:Immunization is the process whereby a person is made immune or resistant to an infectious disease, typically by the administration of a vaccine. Vaccines stimulate the body's own immune system to protect the person against subsequent infection or disease.

Use what you know about natural selection to fill in the blanks in the hypothesis. It should answer the lab question, “What is the effect of the type of food available on the frequency of different types of bird beaks?”
Hypothesis: If the type of food available changes, then…
Answer:
For example, if the seeds that the bird needs to eat is bigger, over time it will adapt to get a bigger beak to eat the bigger seed. The birds that have adapted reproduce and soon more and more birds that have a bigger beak for the bigger seed are more common. If the type of food available changes than the bird will most likely adapt to eat that food.

Explanation:
Why do we need human dna
DNA. Deoxyribonucleic acid (DNA) is a nucleic acid that contains the genetic instructions for the development and function of living things.
All known cellular life and some viruses contain DNA. The main role of DNA in the cell is the long-term storage of information.
We need human DNA since it give us the long term info storage, which is needed
DNA contains instructions for development, survival, and reproduction. DNA sequences must be translated into signals to make proteins, which do most of our body's job.
What is human genome?DNA stores the instructions that are necessary for an organism to grow, maintain its existence, and reproduce itself. In order for these duties to be carried out, the sequences of DNA need to be transformed into messages that can be utilized in the production of proteins. Proteins are the complex molecules that are responsible for the majority of the work that is done in our bodies.
The human genome is comprised of all of the nucleic acid sequences that are found in humans. These sequences are stored as DNA within the 23 chromosome pairs that are found in the nucleus of cells, as well as in a tiny DNA molecule that is located within the mitochondria of each individual cell. In most cases, these are considered to be two distinct components: the nuclear genome and the mitochondrial genome.

What do bears depend on for nutrition.
Answer:
Fish and meat are important sources of protein and fat, though most non-coastal bears rely on carrion (including winter-killed animals)
Explanation:
Some bears, become very effective predators on newborn elk, moose, deer or caribou. Others live in areas where salmon, su.ckers or other fish spawn for part of each year.
When bears emerge from their dens in the spring, food is in short supply. Although bears are hungry, most trees and shrubs won’t leaf for another month and only the grass at lower elevations has begun to green up.

Which is the best reason that a geologist might carry a small dropper bottle filled with hydrochloric acid
when doing fieldwork?
to wash rock samples to make them easier to study
to wear away large areas of rock to see what is underneath
to test for the presence of carbonate minerals in a rock
to use as an emergency eyewash in case rock dust gets in the eyes
Answer:
C, to test for the presence of carbonate minerals in a rock
Explanation:
I did this a few weeks ago on Edge. Hydrochloric acid isn't for rock washing, they wouldn't use it to wear away rocks since it'd ruin the sample I think, and you will go blind if you put it in your eyes
Geologist carry dropper bottle filled with hydrochloric acid when doing fieldwork is to test for the presence of carbonate minerals in a rock.
Test for carbonate mineralsHydrochloric acid is used to test for presence of carbon iv oxide in compounds.
When hydrochloric acid reacts with carbonates, it produces effervescent due to the prensence of carbon iv oxides in the compound.
Geologist will use this acid (hydrochloric acid) to check if the rock sample contains carbonate minerals.
Thus, the best reason that a geologist might carry a small dropper bottle filled with hydrochloric acid when doing fieldwork is to test for the presence of carbonate minerals in a rock.

In Alaskan malamute dogs, the allele for dwarfism (d) is recessive to the allele for normal-size dogs (D) and the allele for white coat colour (r) is recessive to the allele for brown coat colour (R). A breeder crosses two malamute dogs, both of normal-size and brown coat colour multiple times. During these multiple times, the following puppies were produced: Normal-size/brown coat colour: 18 Normal-size/ white coat colour: 6 dwarfism/brown coat colour : 6 dwarfism/white coat colour: 2 What genotype are the parent dogs?
Answer:
DdRr
Explanation:
The parents are heterozygous with the genotype DdRr.
Assuming the two genes are independently assorting. For standard, independently assorting genes, the phenotypic ratio for a dihybrid cross should be 9:3::3:1 with the domiant parental gene having the highest frequency, the recessive parental genes having the lowest frequency and the recombined genes having the intermediate frequencies.
DdRr x DdRr
Progeny
9 D_R_ normal size, brown coat
3 ddR_ dwarf, brown coat
3 D_rr normal size, white coat
1 ddrr dwarf, white coat.
The phenotypic frequency is 9:3:3:1.
Now let us look at phenotypic frequency of the outcome
18:6:6:2 is also equivalent to 9:3:3:1.
Hence, the parents are hetezygous with the genotype DdRr.
In Unicorns diamond eyes are dominant over emerald eyes. Two unicorns with diamond eyes have 4 babies. 1 of their babies has emerald eyes.
A. What is the genotype of the two parent unicorns?
B. What are their chances of having another baby with emerald eyes?
Help pleaseee!!
Answer:
A. Their genotype is Ee.
B. They have a 25% or 1 out of 4 chance of having an offspring with emerald eyes.
Explanation:
A. If one of the babies has emerald eyes, it means it has 2 recessive alleles. so, its genotype is ee. If the parents have diamond eyes, they have to have at least one dominant allele, but they cannot have 2 dominant alleles because one of their offspring have diamond eyes. So, their genotype is Ee.
B. The parents have a 25% or 1 out of 4 chance of having an offspring with emerald eyes, and 75% or 3 out of 4 chance of having offspring with diamond eyes.
Two unicorns with diamond eyes have 4 babies. 1 of their babies has emerald eyes. A. the genotype of the two parent unicorns Ee.
B. Their chances of having another baby with emerald eyes will have 25% or 1 out of 4 chance of having an offspring with emerald eyes.
What is genotype ?A genotype is the set of heritable genes transferred from parents to offspring in next generation; These genes are essential as it involve in encoding specific functional protein needed for body
The genetic characteristics can be physically expressed in an organism called as phenotype.
The genotypes can be written in three form on the basis of allele arrangement such as homozygous dominant (PP), Heterozygous (Pp) and Homozygous recessive (pp).
In case 1 if one of the babies has emerald eyes, that is 2 recessive alleles, then the genotype is ee. If the parents have diamond eyes, with at least one dominant allele, then the genotype is Ee.

Human have cut and frayed the woven tapestry of Earth's biodiversity. List and describe three ways.
Answer:
1. Building into the ecosystem.
2. Hunting animals for sport.
3. Increasing carbon emissions.
Explanation:
All of these are bad for Earth's biodiversity. Building into the ecosystem destroys habitats for animals, which causes the population of that species to decline. Hunting animals for sport decreases populations as well, and doesn't keep the environment in check. Increasing carbon emissions heat up the Earth, leading to colder climates warming up. This, in turn, destroys the ecosystem as well.
Anthropogenic activities and continued neglect of the ecosystem has lead to various deleterious effect on biodiversity.
What is biodiversity?It means the presence of several species of animals, microorganisms, and plants in a habitat.
What is the rivet popper hypothesis?According to this theory, the ecosystem is kept together by thousands of species, just as thousands of rivets hold together an airplane.
It may not affect flight safety at first if rivets are removed but over time, the airframe becomes dangerously weak. Similarly, species extinction in the ecosystem impairs the ecosystem's ability to function properly.
What are the three ways in which humans have affected biodiversity?Habitat loss and fragmentation: It destroys the natural habitat and niche of organisms and leads to their decline
overexploitation: It leads to depletion of the natural resources and increases the risk of extinction of endangered species.
Pollution: It destroys the quality of the habitat of organisms and creates a toxic environment which leads to the decline of species.
