A garden contains 40 flowers, 30 of which are red. What is the frequency of red flowers?
Answer:
0.75
Explanation:
a frequency of 1.0 occurs when all the flowers are red
A garden that contains 40 flowers, 30 of which are red. Then, the frequency of red flowers is 75% of 1:3.
What is Frequency?Frequency is the number of occurrences of a repeating event per unit time. It is also referred to as the temporal frequency for clarity, and is distinct from angular frequency. Frequency is usually measured in hertz (Hz) which is equal to one event per second.
Gene frequency is the fraction or percentage of a population which carries a particular allele at a particular gene locus. In this case, a garden has 40 flowers, in which 30 are red.
Therefore, the frequency of red flowers = Number of red flowers/ Total number of flowers
The frequency of red flowers = 30/ 40 = 75% or 1/3

Answer: O Carbon dioxide
Explanation:
Jesssica is blood type A and her husband Graham is blood type O. She is worried because they are pregnant and their future child has a rare disorder which will require him to need regular blood transfusions. Jessica worries that if their son ends up with type O blood, like his father, it will be hard to get the necessary regular blood transfusions because people with O blood can only accept O blood. What is the likelihood of their child having blood type O?
Answer:
- 50% probability if Jessica has genotype "iAi"
- 0% probability if Jessica has genotype "iAiA"
Explanation:
Blood group in humans is controlled by multiple alleles namely; iA, iB and i. iA and iB are codominant but both dominant over i. The following blood types and their respective genotypes are possible;
- Type A: iAiA or iAi
- Type B: iBiB or iBi
- Type AB: iAiB
- Type O: ii
According to this question, Jessica is blood type A (iAiA or iAi) and her husband Graham is blood type O (ii).
- If Jessica has a genotype iAi, the probability that they will give birth to a child with blood type O (ii) is 50% (see punnet square)
- If Jessica has a genotype iAiA, the probability that they will give birth to a child with blood type O (ii) is 0% (see punnet square).

1. Deoxyribonucleic Acid
2. In biology, a gene is a basic unit of heredity and a sequence of nucleotides in DNA or RNA that encodes the synthesis of a gene product, either RNA or protein. During gene expression, the DNA is first copied into RNA.
3. nucleus
Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA).
4. As described above, DNA can be found in three organelles: the nucleus, mitochondrion, and chloroplast. Only eukaryotes have a nucleus, which is a large structure that's surrounded by a membrane. Nuclear DNA comes in the form of long, linear pieces of DNA called chromosomes.

"Construct an explanation based on evidence for how the principles impact the
process of natural selection"
Answer:
The principles are responsible for the natural selection of organisms.
Explanation:
The principles greatly impact the process of natural selection because these principles are responsible for the natural selection of organisms. If the organisms have all the principles of natural selection, it has more chances of survival as compared to other organisms due to the presence of the favourable characteristics. These favourable characteristics helps the organisms to increase in population because the environment is suitable for them or in other words the organisms can tolerate that environment better than other organisms. for example, polar bear survives in the polar regions because they have a thick skin full of hair that helps in the survival on the cold regions, it is an act of natural selection.

You discover a new species of ascomycete fungus and find that the diploid nuclei of the fungus contain 22 chromosomes. A single diploid cell in an ascus will undergo one round of meiosis, followed in each of the daughter cells by one round of mitosis, producing a total of eight ascospores. If a single, diploid G2 nucleus in an ascus contains 800 nanograms (ng) of DNA, then a single ascospore nucleus of this species should contain how much DNA (ng), carried on how many chromosomes

⭐Is there an advantage for the different anole species being able to occupy different parts of a habitat?
Yes, since the Anolis sagrei inhabits humid lowland forests and dry lowland forests. Apparently it prefers areas that have very low or little ground cover (18, 23).The green anole lizard, Anolis carolinensis, has adapted to living in the tree canopy and can lead to speciation, Different species of anoles have different dewlaps, and very different vegetation.

Which of the following is NOT a correct base pair?
A-C
T-A
C-G
A-T
Answer:
A-C
Explanation:
Hello There!
Remember these are the complementary base pairs
Adenine and Thymine (so the 2nd and 4th one are correct base pairs)
Cytosine and Guanine ( so the 3rd one is a correct base pair)
Hence, A-C would be the incorrect base pair because like stated previously Adenine pairs with thymine not cytosine
1. Which of these is NOT a characteristic of a biome?
A Regions that have the same plant communities
B Regions that have the same animal communities
C Small habitat such as a tree stump that contains its own ecosystem
D Large areas of the Earth that have similar climates and organisms
Small habitat such as a tree stump that contains its own ecosystem is not a characteristic of biome.
What is a biome?A biome is a large geographic region on Earth that is characterized by a specific set of climatic and environmental conditions, as well as a distinctive community of plants and animals. Biomes are defined by their dominant vegetation, which is adapted to the specific climate and environmental factors of the region. There are several different types of biomes, including forests, grasslands, tundra, deserts, and aquatic biomes such as oceans and freshwater ecosystems. Biomes are important for maintaining biodiversity and ecological balance, and are also valuable for human use, providing resources such as timber, food, and water. The study of biomes is an important aspect of ecology, and helps us understand how living organisms interact with their environment.
Which of these is not a characteristic of a biome?c) Small habitat such as a tree stump that contains its own ecosystem. The other options are all characteristics of a biome. Biomes are large areas of the Earth that have similar climates and organisms, and are characterized by the same plant and animal communities. Biomes are typically defined by their predominant vegetation type and are classified based on factors such as temperature, precipitation, and soil type. Therefore, option C is the correct answer.
