Which disappears more rapidly from a population, a deleterious dominant allele or a deleterious recessive allele?
Answer:
Selection is a directional process that leads to an increase or a decrease in the frequency of genes or genotypes. Selection is the process that increases the frequencies of plant resistance alleles in natural ecosystems through coevolution, and it is the process that increases the frequencies of virulence alleles in agricultural ecosystems during boom and bust cycles.
Selection occurs in response to a specific environmental factor. It is a central topic of population and evolutionary biology. The consequence of natural selection on the genetic structure and evolution of organisms is complicated. Natural selection can decrease the genetic variation in populations of organisms by selecting for or against a specific gene or gene combination (leading to directional selection). It can increase the genetic variation in populations by selecting for or against several genes or gene combinations (leading to disruptive selection or balancing selection). Natural selection might lead to speciation through the accumulation of adaptive genetic differences among reproductively isolated populations. Selection can also prevent speciation by homogenizing the population genetic structure across all locations.
Selection in plant pathology is mainly considered in the framework of gene-for-gene coevolution. Plant pathologists often think in terms of Van der Plank and his concept of "stabilizing selection" that would operate against pathogen strains with unnecessary virulence. As we will see shortly, Van der Plank used the wrong term, as he was actually referring to directional selection against unneeded virulence alleles.
A deleterious dominant allele would disappear more slowly from a population compared to a deleterious recessive allele.
What is a deleterious dominant allele?In the case of a deleterious dominant allele, the individual possessing the allele will always express the negative trait associated with it, making it easier to identify and potentially select against. In contrast, a deleterious recessive allele may not be expressed in individuals who carry only one copy of the allele, as the normal copy of the gene can still produce enough functional protein to mask the effects of the deleterious allele.
As a result, the deleterious recessive allele can persist in a population as carriers pass the allele on to their offspring without showing any negative effects themselves. However, over time, the recessive allele may become more common in the population, increasing the likelihood of two carriers mating and producing offspring that express the deleterious trait.

Are atoms and molecules alive? Why or why not?
(This is 7th grade science)
Answer:
No
Explanation:
Atoms and molecules are not alive as they do not exhibit all, or any, of the eight characteristics of life. Cell theory also states that a cell is the smallest unit of life, and atoms and molecules are much, much smaller than a cell — in fact, they make up cells.
Therefore, they are not considered living things.
I hope this helped you, and if you would like a more in-depth explanation, please let me know!
Answer:
Nope :))
Explanation:
Although molecules and atoms are both apart of something that is living, this doesn't mean a single atom or molecule can live on their own.

Please and don’t waste my time bu saying that you don’t know the answer. thank you :) I hope you have a nice day
Answer:
Plants exchange oxygen and carbon dioxide. The oxygen is used for respiration and is also a waste product of photsynthesis. The carbon dioxide is used for photsynthesis.
During the day time, the stomata of the plant will open to let the carbon dioxide in for photsynthesis. Cabron dioxide diffuses into the leaf down a concetration gradient. oxygen will leave the leaf down the concentration gradient.
This process is the gas exchnage of plants.
How stomata open: Stomata open during the dayby absorbing water vapor, become turgid and and open. During the night, the stomata becomes flaccid and floppy. this causes it to close.

Describe the reproductive cycle of most scyphozoans
The reproductive cycle of most scyphozoans is early in the spring, ephyrae transform into young medusae. These develop over the summer, achieve sexual maturity, reproduce sexually, and then perish.
What is a reproductive cycle?The reproductive cycle is the one that shows the reproduction of an organism. Scyphozoa reproduce both sexually (medusa) and asexually (polyp).
While both types exist, the medusa (sexual) form is more common. Sexual reproduction is not an inside process. Males release sperm into the sea, while females release eggs.
Most scyphozoan jellyfishes, including most large jellyfishes, have a two-part life cycle: free-swimming medusa and bottom-dwelling polyp (though there are significant exceptions).
Therefore, most scyphozoans reproduce in the spring, when ephyrae convert into young medusae. These grow over the summer, reach sexual maturity, reproduce sexually, and then die.

As Earth revolves around the Sun, the number of daylight hours varies from place to place. In which location would the number of daylight hours remain constant?
( North Pole, Equator, Anartica, Prime Meridian)
Answer:
i think its the Equator im not that sure
The number of daylight hours will remain constant at : ( B ) The equator
As the earth continues to revolve around the sun, It brings about the changes in seasons ( winter summer, spring and autumn ). During each season the daylight hours varies slightly across each place. While
The equator receives sufficient sunlight which makes its daylight hours fairly constant as the earth revolves around the sun. also the temperature at the equator is warm all round the seasons.
Hence we can conclude that the number of daylight hours will remain constant at the Equator.

Write short notes on Fertilization.
Answer:
Fertilization is the fusion of haploid gametes, egg and sperm, to form the diploid zygote. Note though there can be subtle differences in the fertilization process which occurs naturally within the body or through reproductive technologies outside the body, the overall product in both cases is a diplod zygote.

why do cells need to go through mitosis
Answer:
Mitosis is a way of making more cells that are genetically the same as the parent cell. It plays an important part in the development of embryos, and it is important for the growth and development of our bodies as well. Mitosis produces new cells, and replaces cells that are old, lost or damaged.

During the cell cycle, the cell duplicates its genetic material. Moreover, also during this cycle, the cell synthesizes all materials required for its division.
The cell cycle can be divided into an interphase and a mitotic (M) phase.
The interphase is in turn divided into three phases: Growth 1 (G1) phase, Synthesis (S) phase and Growth 2 (G2) phase.
During the S phase, the cell duplicates its genetic material by a process called DNA replication.
During G1 phase and G2 phase, the cell grows and synthesizes all materials (i.e., proteins) required to enter into the M phase.
