gamete definition biology
The mature reproductive or sex cell known as a gamete is capable of fusing with another haploid reproductive cell to create a diploid zygote and has a haploid number of chromosomes (i.e., 50% of the genetic material or only one set of dissimilar chromosomes).
The fusion (or combining) of two gametes, specifically a male and a female gamete, results in the zygote. Fertilization is the process by which two gametes combine to form a zygote.
One of the gametes is typically larger and non-motile, which is characteristic. It is also referred to as an ovum or an egg cell. The second gamete cell is smaller and motile. It is also known as a sperm cell or a male gamete. Each human gamete has 23 chromosomes, and their fusion produces an individual.

which lipoprotein particle is generated by the action of lipoprotein lipase on vldl particles?
Lipoprotein particles that is generated by the action of lipoprotein lipase on VLDL particles. Lipoprotein lipase is an enzyme that is responsible for breaking down triglycerides in lipoprotein particles in the bloodstream.
When LPL acts on very low-density lipoprotein particles, it converts them into intermediate-density lipoprotein (IDL) particles by removing some of the triglycerides.IDL particles are therefore the lipoprotein particle that is generated by the action of lipoprotein lipase on VLDL particles. IDL particles are intermediate in size and density between VLDL and low-density lipoprotein (LDL) particles, and they can either be taken up by the liver or further broken down into LDL particles. LDL particles are often referred to as "bad" cholesterol because high levels of LDL in the blood are associated with an increased risk of cardiovascular disease.

At what stage does a cell become committed to the cell cycle?
A cell becomes committed to the cell cycle at the G1/S transition.
This transition marks the start of the cell cycle and marks the point at which the cell has decided to divide and is no longer able to return to the G1 phase. At this point the cell begins to replicate its DNA, transcribe its genes and synthesize proteins required for the cell cycle. This is the point at which the cell is committed to the cell cycle and will continue to progress through the cycle until it enters the G2 phase.The cell cycle, also known as the cell-division cycle, is a series of actions that leads to the division of a cell into two daughter cells. These events involve the duplication of its DNA (DNA replication) and a few of its organelles, followed by the process of cell division, which entails splitting the original cell into two daughter cells and dividing its cytoplasm, chromosomes, and other constituents.

c. The information in DNA is transcribed to RNA and then translated into proteins. A gene's DNA sequence is copied to create an RNA molecule during transcription.
Because the DNA sequence is rewritten, or "transcribed," into a comparable RNA "alphabet," this process is known as transcription. To develop into a mature messenger RNA in eukaryotes, the RNA molecule must go through processing (mRNA).
For the purpose of specifying the polypeptide's amino acid sequence during translation, the mRNA sequence is decoded. The name translation refers to the process of converting the nucleotide sequence of the messenger RNA sequence into the entirely different "language" of amino acids.

Is allele frequency the same as phenotype frequency?
Allele frequency is not the same as phenotype frequency. This is because allele frequency explains the frequency of occurrence of a particular gene or allele, not a trait.
Allele frequency describes the frequency of a particular gene or allele that shows up in a given population. Whereas phenotype frequency describes the frequency of occurrence of a particular trait in a given population. p and q are used to denote allele frequencies. The phenotype frequency gives the frequency of traits.
For example, let's consider the occurrence of the white and purple colors of a flower. The allele for purple is W and for white is w. The frequency of occurrence of W and w give the allele frequency.

Which does not cause rapid growth in a population?
A. elimination of a pollutant
B. elimination of predators
C. increase in food supply
D. introduction of a new parasite
E. introduction into a new habitat
Answer:
B. elimination of predators does not cause rapid growth in a population.
Explanation:
B. elimination of predators does not cause rapid growth in a population. In fact, the elimination of predators often leads to a decrease in the population size of the prey species, as without the predation pressure, the prey population may exceed the carrying capacity of the environment, leading to increased competition for limited resources and other factors that can limit population growth.
A, C, D, and E can all cause rapid growth in a population, although the specific effects may depend on the species and the particular circumstances. For example, the elimination of a pollutant can improve the health and survival of individuals in a population, leading to increased reproduction and population growth. Similarly, an increase in food supply can lead to increased reproduction and survival, while the introduction of a new parasite can reduce the population size of the host species, potentially leading to an increase in the survival and reproduction of the remaining individuals. Finally, the introduction of a population into a new habitat can often lead to rapid population growth as the population expands into an area with more resources and fewer limiting factors.

morgan coin the term genes from the particles of inheritance to which
mendel referred this statement is True. The term "gene" was first coined by the geneticist Thomas Hunt Morgan in 1909.
Morgan's work with the fruit fly Drosophila melanogaster led him to propose that the factors responsible for the inheritance of traits were located on chromosomes, which were being passed from parent to offspring during cell division. Morgan called these factors "genes," a term derived from the Greek word "genesis," meaning origin or birth.
Mendel, who conducted his famous experiments with pea plants in the mid-19th century, did not use the term "gene" to describe the particles of inheritance that he studied. Instead, Mendel referred to these particles as "factors" or "unit characters." It was only later, with the advent of molecular biology and the discovery of the physical structure of DNA, that the term "gene" became synonymous with the particles of inheritance that Mendel had described.

What is definition of zygote in biology?
In biology, a zygote is a single cell that is formed when a sperm cell fertilizes an egg cell. The zygote is the first cell of a new individual and contains all the genetic information necessary for the development of an organism.
After fertilization, the zygote undergoes a series of cell divisions, called mitosis, and develops into a multicellular embryo. As the embryo develops, cells differentiate and become specialized for specific functions, forming various tissues and organs. The zygote is diploid, meaning it contains two sets of chromosomes, one from each parent. The chromosomes carry genetic information in the form of genes, which determine an individual's physical and biological traits. The zygote is a crucial stage in sexual reproduction, as it combines genetic material from both parents and gives rise to a new individual. In some organisms, such as plants, the zygote can remain dormant for a period of time before developing into a new organism.
