What is another example of a resource that has limited supply
Answer:
Fossil fuels such as oil, natural gas, and coal are examples of nonrenewable resources. Humans constantly draw on the reserves of these substances while the formation of new supplies takes eons.
Explanation:
The resources that we value—time, money, labor, tools, land, and raw materials—exist in limited supply. There are simply never enough resources to meet all our needs and desires.

Explanation:
Dr. Mrs. Brown has Rh+ blood, but her father is Rh-. What must her full blood type genotype be?
Answer:
Her full blood type genotype is Dd.
Explanation:
Rh (Rhesus) factor is a type of protein found on the outside of red blood cells. It is genetically inherited. An individual that has this protein is Rh-positive, and the one that doesn't is Rh-negative. The Rh-positive gene is dominant, while the Rh-negative gene is recessive. This means that a person must inherit at least one dominant (D) allele from their parents in order to be Rh-positive.
If Dr. Mrs. Brown is Rh-positive, and her father is Rh-negative, her mother must be Rh-positive (DD or Dd), as well. Her father has two recessive alleles (dd), which means that Dr. Mrs. Brown must have one recessive allele. Since she is Rh-positive, she must have one dominant allele. This makes her genotype Dd.

Which statement illustrates bias in scientific research?(1 point)
A. A microbiologist publishes data funded by the National Institutes of Health that does not support their original hypothesis.
B. A botanist publishes data about plant growth that does not support their original hypothesis and is replicable.
C. An ecologist publishes data funded by a construction company which supports their original hypothesis that an endangered animal's territory is not endangered.
D. A zoologist publishes incomplete data on sloths which supports their original hypothesis and notes that more research is required.
Answer:
D
Explanation:
The statement that illustrates bias in scientific research is an ecologist publishes data funded by a construction company that supports their original hypothesis that endangered animal's territory is not endangered (option C)
In scientific research, bias can occur when the results or processes are manipulated on purpose. This usually occurs if:
The researcher wants the hypothesis to match the resultsThe researcher or sponsor has an economic interestScientific research occurs in situation B because it is convenient for the construction company to show that endangered animal's territory is not endangered as this would allow the company to build in certain areas and therefore, they are likely to manipulate the results of this research.
According to this, option B shows scientific bias. On the other hand, other options do not show bias because in these the results do not seem to be manipulated.

Why is uranium lead dating better than radiocarbon dating?
Answer:
Uranium-238 has a much longer half-life of 4.5 billion years versus Carbon-14's 5,730 years.
Explanation:
Radioactive Carbon-14 or [tex]^{14}C[/tex] is typically formed in the upper atmosphere. In plants, it gets incorporated into organic molecules through photosynthesis, and this material is ingested by consumers.
It is used for the process of radiocarbon dating of fossils and formations. Radioactive isotope dating is an effective means of identification due to the unstable nature of the isotope used and the predictable rate of decay.
Over time they decay to give off an electron, in an effort to become a more stable element. For instance, [tex]^{14}C[/tex] has a relatively short half-life and half the in a sample becomes Nitrogen over a few thousand years (5,730 years).
However, for older samples, other isotopes are used because their long half-life may range between a million to billions of years. Uranium-238, with a half-life of 4.5 billion years is often used in geochronology; uranium-lead dating is suitable for older specimens.

In tomatoes, red fruit color is dominant, R, to yellow fruit color, r. A farmer has tomatoes that produce either red or yellow tomatoes. He has signed a contract with a large seed company to provide pure, RR, and pure yellow seeds, rr. They do not want any hybrids. How could the farmer tell if his tomatoes are pure or hybrid?
Answer:
He should perform a "testcross" by crossing the tomatoes in question with yellow-fruited plants.
If they are pure, all offpsring will be Red: RR x rr = all Rr
If they are hybrids (heterozygous), half the offspring will have yellow fruits: Rr x rr = 1:1 (red to yellow)

1 . phylum The two-name system of naming living things used in classification
2 . class All life on earth
3 . kingdom A taxonomic category containing a group of similar orders
4 . International Code of Nomenclature In plant classification, a grouping of similar classes
5 . order An elaborate set of rules for naming organisms
6 . binomial nomenclature The largest taxonomic category
7 . taxon A taxonomic category containing a group of similar families
8 . division In classification (other than plant), a grouping of similar classes
9 . biosphere The categories used in classifying plants and animals
Answer:
Please find the correctly matched terms with their definition below:
Explanation:
1. Binomial nomenclature: As the name implies i.e. Binomial meaning"two", binomial nomenclature is the two-name system of naming living things used in classification.
2. Biosphere: Biosphere refers to all life on Earth including plants, animals, microbes etc.
3. Class: Class is one of the seven levels of classification, which is a taxonomic category containing a group of similar orders.
4. Phylum: Phylum is also a level of classification used majorly for classifying plants. In plant classification, It is a group of similar classes.
5. International Code of Nomenclature: Abbreviated as IUCN, it is an elaborate set of rules for naming organisms in taxonomy.
6. Kingdom: Kingdom is the least specific taxon. Kingdom represents the largest taxonomic category containing most organisms.
7. Order: Another level of classification that describes a taxonomic category containing a group of similar families.
8. Division: Division is a taxon used instead of phylum when a plant is not involved. In classification (other than plant), phylum is a grouping of similar classes.
9. Taxon: Taxon refers to the categories used in classifying plants and animals.
Answer:
1. Species refers to the biological term that signifies the smallest unit or the basic unit of classification. Thus, 1 can be correctly matched with species. 2. The Arthropods refers to the species that exhibits an exoskeleton, paired jointed legs and segmented body. Thus, 2 can be correctly matched with Arthropods and animal characteristics. 3. The largest phylum of animals is Arthropods. Thus, 3 can also be correctly matched with Arthropod. 4. The Tracheophyta signifies towards the green plants that exhibit conductive tissues for mediating nutrients and water through them. Thus, 4 can be correctly matched with Tracheophyta. 5. Taxonomy refers to the branch of science that deals with the classification of species. Thus, 5 can be correctly matched with taxonomy. 6. The order is considered as a group of families. Thus, 6 can be correctly matched with order. 7. Tracheophyta is considered as the largest division of plants. Thus, 7 can be correctly matched with Tracheophyta.

Explain how an algal bloom affects the oxygen levels in a lake ecosystem.
Answer:
Algal bloom causes by eutrophication (when excess nutrients run into a body of water). Eutrophication provides nutrients for algal bloom. As a result, there is an increasing in algal bloom population. Increasing in algal bloom population can block the light that is needed by other organisms. This could impact these organisms survival. Furthermore, when these algae die, their body sink into the bottom of the sea, which consider as nutrients for bacteria, increasing bacteria population. This means that the respiration rate by bacteria is increasing as well. When bacteria respire, they need to absorb oxygen. Over time, these oxygen level will eventually decrease and later form a dead zone.
