In a certain plant, yellow leaves are dominant (Y) and red leaves are
recessive (y). A plant with genotype Yy and a plant with yy are crossed. If they have four offspring, how many would you predict would have red leaves? (Hint: Draw a Punnett square to help you determine the answer.)
A. 4
B. 3
C. 2.
D. 1
Answers
Answer: C
Explanation: When a plant with genotype yy and Yy are crossed there will be two yellow offsprings with genotype Yy(where yellow is dominating) and another two with yy(where leaves are completely red)
According to the information provided, yellow leaves (Y) are a dominant characteristic over red leaves (Y), which means that if the allele for yellow is paired with allele for red leaves as can be seen in Punnett square, it will hide the expression of red leaves. So, the correct option is D.
What is Punnett Square?The genotypes of a specific crossing or breeding experiment are predicted using the Punnett square, a square diagram. Biologists use the figure to calculate the likelihood that a child will have a specific genotype.
The information given indicates that yellow leaves (Y) have a dominant trait above red leaves (Y), that implies that if the alleles for yellow and red leaves are linked together as shown in Punnett square, this will conceal the manifestation of red leaves.
For red leaves, the genotype is yy, while the two potential genotypes for yellow leaves are YY and Yy. Parents have the genotypes Yy and Yy. When they are crossed, one of every four offspring that results will have red leaves.
Therefore, the correct option is D.

How is nominal scale type related to diversity? No links no trolls plzzzzzzzzzzz
Answers
Answer:
A nominal scale describes a variable with categories that do not have a natural order or ranking. You can code nominal variables with numbers if you want, but the order is arbitrary and any calculations, such as computing a mean, median, or standard deviation, would be meaningless.
A nominal scale is a scale (of measurement) that uses labels to classify cases (measurements) into classes. Some examples of variables that use nominal scales would be religious affiliation, sex, the city where you live, etc. Example. One example of a nominal scale could be "sex".
For example, Race is a nominal variable having a number of categories, but there is no specific way to order from highest to lowest and vice versa.

amount of sunlight
trophic levels
species richness
vegetation
Answers
Answer:
1. A population of 300 deer will remain at about 300
2. community
3. amount of sunlight
Explanation:
1. Carrying capacity is defined as the maximum population size of a biological species that can be sustained by that specific environment, given the food, habitat, water, and other resources available. Therefore if a population has reached its carrying capacity, it will most likely remain at that size.
2. A community is defined as all of the populations of different species that live in the same area and interact with one another. Clownfish, seahorses, and sea grass are all different species living in an area together and interacting with each other. This example does not show a population, nor a species, nor biome, since a population is a group of organisms of the same species, and a biome is a distinct biological community that has formed in reponse to a shared physical climate.
3. Abiotic factors are non-living factors which affect an ecosystem.

The food web above represents feeding relationships in a biological community near a deep-sea hydrothermal vent. Hydrothermal vents are geysers on the seafloor that gush super-heated, mineralrich water. The seawater surrounding hydrothermal vents typically contains carbon dioxide (CO2), molecular hydrogen (H2), hydrogen sulfide (H2S), and methane (CH4). Sunlight, however, fails to reach the seafloor where deep-sea hydrothermal vents are located. As part of an investigation, researchers collected living specimens from an area near a deep-sea hydrothermal vent. Mussels in the collection were found to be dependent on molecular hydrogen in seawater. Also, the researchers discovered multiple species of bacteria living in the gills of the mussels.
Mussels use gills for filter-feeding and gas exchange with the surrounding seawater. On the basis of their experimental results, the researchers hypothesized that some bacteria living in the gills of the mussels are capable of chemosynthesis. Which of the following best explains how biological communities near deep-sea hydrothermal vents can exist in a habitat lacking sunlight?
a) Environmental conditions on some distant planets resemble those experienced by organisms
living near hydrothermal vents.
b) Heterotrophs metabolize carbon-containing compounds produced by the photosynthetic
organisms that live on the seafloor.
c) Some organisms rely on energy captured from inorganic compounds to drive basic biological processes.
d) Some organisms that can tolerate high temperatures are single celled, whereas others are multicellular.
Answers
Answer: c) Some organisms rely on energy captured from inorganic compounds to drive basic biological processes.
Explanation:
Deep-sea hydrothermal vents are hot spots of geothermal water. The organisms living in deep-sea vents cannot obtain energy from sunlight. They are dependent on chemosynthesis, which involves the utilization of inorganic substances to produce organic substances, which allows their survival and act as a source of energy. In the given situation, bacteria present on the surface of mussels are capable of chemosynthesis also the mussels are dependent upon inorganic hydrogen in seawater. Thus chemosynthesis supports the survival of organisms living in the deep sea vents.

A. a protein
B. a codon
C. a Mutagen

Answers
Answer:
DNA molecule
Explanation:
Each sequence of three nucleotides is called a codon. Therefore, the correct answer is option B.
Codons are named by the request for their bases. The three stop codons in mRNA are UAA, UAG, and UGA, where U represents uracil, A for adenine, and G for guanine. Stop codons signal the end of protein synthesis. They can be found in DNA or mRNA.
They are three-nucleotide sequences that encode a particular amino acid. During the translation process, the tRNA (transfer RNA) molecules contain anticodons that aid in the transfer of amino acids to the mRNA.
A codon is a sequence of three nucleotides in DNA or RNA, also known as a trinucleotide. It is a unit of genomic information that encodes a specific amino acid or signals the end of protein synthesis (stop signals).

What is a likely reason why dark fur has not evolved in the population of mice that live on this lava flow?
Answers
There could be several reasons why dark fur has not evolved in the population of mice that live on a particular lava flow. One possible reason is that dark fur may not provide any adaptive advantage to these mice in their specific environment.
What is the significance of the dark fur mouse?In the case of dark fur in mice, there are several factors that could explain why it has not evolved. One possible explanation is that dark fur may be maladaptive in the environment of the lava flow. If the lava flow has a high ambient temperature, dark fur may absorb more heat and cause the mice to overheat, which could be detrimental to their survival. On the other hand, if the lava flow has low light conditions, dark fur may not provide any camouflage advantage and may make the mice more visible to predators.
Hence, one possible reason is that dark fur may not provide any adaptive advantage to these mice in their specific environment.
