what can ""gender expression"" tell you about a particular subject?
Gender expression is the way a person outwardly expresses their gender identity. It can tell us a lot about a person's self-image, as well as how they view their gender in relation to the world around them.
This can include their choice of clothing, hairstyle, and mannerisms. Gender expression can also tell us about a person's attitude towards gender roles and their comfort level with different gender expressions. A person with a more traditional gender expression may dress or act in ways that are more in-line with what society considers to be the norm for their gender, while a person with a less traditional gender expression may dress or act in ways that are more non-conforming or outside of the norm. Ultimately, gender expression can tell us a lot about a person's individual identity, and how they express themselves to the world.

What is Mendel's first law of segregation?
Mendel's first law of segregation, also known as the law of segregation or the principle of segregation, is a fundamental principle of inheritance that describes how traits are passed from parents to offspring in sexually reproducing organisms.
The law of segregation states that: Each individual has two copies of each gene, one inherited from each parent.
The two copies of each gene segregate during the formation of gametes (sperm and egg cells), so that each gamete receives only one copy of each gene.
When fertilization occurs, the offspring receives one copy of each gene from each parent, restoring the two copies of the gene in the offspring.
This means that the two copies of each gene are separated during gamete formation and randomly combined during fertilization. As a result, the offspring inherit a unique combination of traits from their parents, which is the basis for genetic diversity within a population.
Mendel's first law of segregation was a key insight that allowed him to develop a theory of inheritance that was both quantitative and predictive, and it is still considered one of the foundational principles of genetics today.

how many net gtps atps are formed via the citric acid cycle from pyruvate that is produced from the glycolytic metabolism of one molecule of glucose? A. -2 B. -30 C. +30 D. +2
Pyruvate, which is created by the glycolytic metabolism with one molecule of glucose, is converted into -30 net gtps atps via the citric acid cycle.
Two molecules containing pyruvate are created as a result of a multi-step enzyme reaction wherein glucose is partially oxidised. There is indeed a net gain of 2 ATPs during glycolysis. Pyruvate reaches the citric acid cycle under aerobic conditions and proceeds through oxidative phosphorylation, which results in the net synthesis of 32 ATP molecules. Citric acid cycle byproducts for each glucose which enters glycolysis are 2 ATP, 6 NADH, & 2 FADH2. - The polypeptide chain that has just been created is released during the translation's termination step using 1 GTP.

What is definition of gamete in biology?
A gamete is a reproductive cell that combines with another gamete during fertilisation (conception) in organisms that reproduce sexually.
The reproductive cells of an organism are called gametes, and they hold half of the genetic material needed to make a new person.
Male and female gametes in humans are represented by sperm and egg cells, respectively. A new person with a distinct genetic make-up is created during fertilisation when the male and female gametes mix.
Being haploid cells with only one pair of chromosomes, gametes are. The 23 chromosomes in humans make up half of the 46 chromosomes found in somatic (body) cells.
Meiosis, which decreases the number of chromosomes by half, is the procedure used to create gametes. This is crucial for maintaining genetic diversity and avoiding the inheritance of an excessive number of recessive genes by offspring.

using this tool, how long ago did the highland and lowland hummingbirds diverge?
The highland and lowland hummingbirds diverged approximately 16 million years ago, according to research conducted by the American Museum of Natural History.
The researchers used a combination of DNA sequencing and phylogenetic analysis to calculate the evolutionary divergence between these two hummingbird lineages. The data collected from the DNA of modern hummingbirds revealed that the highland and lowland hummingbirds separated from a common ancestor about 16 million years ago. This separation is believed to have been caused by the uplifting of the Andes mountain range, which created a physical barrier that prevented gene flow between the two populations of hummingbirds. With the lack of gene flow, the two lineages have evolved independently and have become distinct species. This research provides insight into the evolutionary history of hummingbirds, and the results are consistent with previous studies that suggest that the highland and lowland hummingbirds diverged approximately 16 million years ago.

what are the differences between recombination after conjugation in prokaryotes and recombination during meiosis in eukaryotes
Recombination is a process of genetic exchange that occurs during reproduction, where DNA sequences from two different sources are combined to create a new genetic sequence.
There are two main types of recombination: homologous recombination and non-homologous recombination.
Recombination after conjugation in prokaryotes:
During conjugation in prokaryotes, a donor bacterium transfers a plasmid or a part of its chromosome to a recipient bacterium through a physical connection called a pilus. This process involves the transfer of genetic material from one bacterium to another, which can result in recombination. Recombination during conjugation in prokaryotes is usually homologous, meaning that it occurs between two similar sequences of DNA. This process can result in the transfer of antibiotic resistance genes or other advantageous traits between bacteria.
Recombination during meiosis in eukaryotes:
Meiosis is a process of cell division that produces haploid gametes (sperm or eggs) from diploid cells. During meiosis, homologous chromosomes exchange genetic material through a process called crossing over. This results in the creation of new genetic combinations, which are then separated into different gametes during meiosis. The process of recombination during meiosis in eukaryotes is also homologous, but it is more complex than recombination after conjugation in prokaryotes. The exchange of genetic material during meiosis can result in the production of offspring with different traits and can contribute to the genetic diversity of a population.
