Answer:
The allelic frequency for pointed ears is 0.5 (50%).
Explanation:
The frequency of alleles in a population must add up to 1 (100%).
The allelic frequency for pointed ears is 0.5 (50%).
What is allelic frequency ?The allele frequency represents the incidence of a gene variant in a population. Alleles are variant forms of a gene that are located at the same position, or genetic locus, on a chromosome.
What is the difference between gene frequency and allele frequency?Gene frequency, which more or less refers to the allele frequency, is the measurement where the number of repeats of the same allele is measured over a certain period of time.

What did Mendel study that lead him to his discovery
Answer:
A monk, Mendel discovered the basic principles of heredity through experiments in his monastery's garden. His experiments showed that the inheritance of certain traits in pea plants follows particular patterns, subsequently becoming the foundation of modern genetics and leading to the study of heredity.
Explanation:
Answer:
Mendel studied the genetics of pea plants.
Explanation:
Mendel looked at the pea plants in his monastery garden to determine genetics. He found that some plants had white flowers, while some did not, and he used that discovery to determine the genetics of the plants.
How is fish adapted? Write any two adaptational characters of them.
DNA carries the information needed to make proteins. How is this information used to make proteins?
Answer:
The information contained in DNA is expressed giving rise to proteins, through transcription processes, a step by which the information is transferred to a messenger RNA molecule (m-RNA) and, through the process of translation, the message carried by m-RNA is translated into protein.
Answer:
DNA is transcribed into mRNA. Ribosomes "read" the mRNA and translate each group of three nucleotides into amino acids to build proteins, with the help of tRNA.

Yalll are smart right well I am give you 50 POINT lol you have to do this correctly :3
Answer:
Top to bottom: 5, 3, 2, 4, 1
Explanation:
I'll take a shot! Here I go!
5 (Sun) = top; we get all our energy from the sun
Then 3 (plants); plants can convert sunlight into food for themselves via photosynthesis
Then 2; we're talking about herbivores that eat plants, right?
Then 4; these are probably~ carnivores
Then 1; when a living thing dies, these guys consume the corpse and return the energy to the ecosystem
Have a great day!
Answer:
Sun
Primary Producers
Primary Consumers
Secondary Consumers
Decomposers
Explanation:
Energy coming from the sun is converted into chemical energy (or glucose) by plants. Primary consumers (herbivores) eat those plants and gain the energy they produced. Secondary consumers (carnivores probably) eat the primary consumers and gain that energy. Then they die and decomposers (fungi) return their energy into the soil.
Describe all the tissues and cell types that are found in a leaf and describe how these individual parts work together to accomplish processes of photosynthesis.
Explanation:
While individual plant species are unique, all share a common structure: a plant body consisting of stems, roots, and leaves. They all transport water, minerals, and sugars produced through photosynthesis through the plant body in a similar manner. All plant species also respond to environmental factors, such as light, gravity, competition, temperature, and predation.

Explain the role that hooved animals, such as cows, play in regenerative farming.
Answer:
I hope this helps
Explanation:
As animals move, their hooves break up the soil, compacting inedible plants and allowing nutrients and sunlight to new plants—essentially speeding up the building of soil organic matter, with crushed leaves and stalks creating a natural mulch. This better equips the soil for germinating seeds.
Sound waves travel better through solid than through a gas. Explain why this is true.
Answer:
solids are more tightly packed together (the molecules) than liquid or gas so it allows it to travel through vetter/faster
Answer:
Explanation: Solids are packed together tighter than liquids and gases, hence sound travels fastest in solids. The distances in liquids are shorter than in gases, but longer than in solids. Gases are the slowest because they are the least dense: the molecules in gases are very far apart, compared with solids and liquids
What differentiates Hela cells from other human cells?
Answer:
a normal cell contains 46 chromosomes whereas HeLa cells contain 76 to 80 (ref) total chromosomes, some of which are heavily mutated (22-25), per cell.
Explanation:
The main difference between Hela cells from other human cells is that a normal cell contains 46 chromosomes whereas HeLa cells contain 76 to 80 (ref) total chromosomes, some of which are heavily mutated (22-25), per cell.
What happens when the involvement of hela takes place?The involvement of hela made to the developing field of genetics is a lot was educated about cell reproduction, DNA and mapping genetics. The hela cells prepared them ideal for use in the polio vaccine trials because they were more liable than other cultured cells.
Cancer cells such as Hela cells escape to normal cell cycle by mutations that lead to the misexpression and/or overexpression of regulatory molecules (e.g., cyclins and cyclin-dependent kinases) and faulty checkpoint control of the cell cycle.
The control of the cell cycle depends on 1-cyclins and cyclin-dependent kinases (CDKs) that regulate the cell cycle by a cascade of protein phosphorylations and 2- a group of checkpoint controls that monitor the completion of critical cellular events.
Therefore, The main difference between Hela cells from other human cells is that a normal cell contains 46 chromosomes whereas HeLa cells contain 76 to 80 (ref) total chromosomes, some of which are heavily mutated (22-25), per cell.

The correct answer is C. Gardeners choose which plants they let reproduced based on the plant traits.
Explanation:
In general, selective breeding involves the intervention of humans in the reproduction of species, this includes mainly plant and animal species. Moreover, in selective breeding, humans choose which specific species or individuals reproduce to favor certain traits. For example, a farmer might allow only the biggest cows to reproduce because this will lead to bigger calves. In this context, the option that shows selective breeding is C because this shows the intervention of humans in reproduction by selecting the individuals that will reproduce.
would you expect a plant to produce more oxygen on a cloudy day or a sunny day? explain
Answer:
You would expect a plant to produce more oxygen on a sunny day because there are more sun rays available to plants so photosynthesis is easier to maintain, as well as oxygen production.
