Answer: There are many reasons why people might stalk other people. In some cases, a stalker may be motivated by a desire to control or dominate the person they are stalking. In other cases, a stalker may be motivated by a fixation on the person they are stalking, or by a belief that the person is somehow responsible for their problems. Additionally, some stalkers may have underlying mental health issues that contribute to their behavior. In general, however, stalking is a way for the stalker to exert power and control over their victim.
Answer: Because they are creepy, trying to murder (sed person) a fanboy of the person they're stalking, or they have some sort of mental problem that makes them want to start stalking someone they know such as a family member, friend, past enemy, current enemy, or crush.
Explanation: This can be caused by all sorts of trauma, past experiences that greatly enhanced their lust for that person, and so on. They could just be a psychopath which ties into the point of my mental issue about the person stalking the victim and they are most likely trying to kill them.

In a myofibril, a thick filament is composed of pairs of _____ molecules intertwined together
In a myofibril the thick filament is composed of pairs of myosin molecules that are intertwined together.
The protein myosin makes up thick filaments. Near the M line, a myosin molecule's tail joins with other myosin molecules to form the thick filament's core region, while the thick filament's heads align on either side where the thin filaments overlap. The thick and thin myofilaments that make up the myofibrils are what give the muscle its striped appearance. Along with two other muscle regulating proteins, tropomyosin and troponin, the thick filaments are made up of strands of the protein myosin, while the thin filaments are made up of strands of the protein actin.
In addition to myosin, which forms the thick filament's backbone, four additional proteins—titin, myomesin, obscurin, and myosin binding protein-C—that are tightly attached to the filament also perform crucial structural and regulatory functions.

what is generally the starting material for whole-genome shotgun sequencing of genomic dna? see section 16.1
The starting material for whole-genome shotgun sequencing of genomic DNA is overlapping fragments of genomic DNA.
The DNA sequence of an organism's genome can be ascertained in a lab using shotgun sequencing. The process entails randomly dividing the genome into tiny DNA fragments that are then individually sequenced. To reconstruct the genome, a computer program searches for overlaps in the DNA sequences and uses those overlaps to put the fragments back together in the right order.
Shotgun sequencing involves randomly slicing the genome into small, sequencing-ready pieces (1 to 2 kbp in length). After being ligated into an appropriate vector, the fragments are partially sequenced. Each fragment can yield 400–500 bp of sequence in a single sequencing run.
Hence, small fragments are sequenced and organized with computer.

which of the following will occur after ovulation? group of answer choices the corpus luteum prepares to become a corpus albicans. the corpus luteum secretes estrogen only. the endometrium enters its secretory phase. the secretion of anterior pituitary gonadotropins is enhanced.
The interaction of hypothalamic and anterior pituitary hormones with reproductive tissues and organ hormones regulates the human male and female reproductive cycles. In both sexes, the hypothalamus regulates and causes pituitary hormone release.
The normal menstrual cycle is a sequential event in which the hypothalamus secretes GnRH, the pituitary gland secretes follicle stimulating hormone and luteinizing hormone (LH), and the ovary responds to those hormones by recruiting a dominant follicle and secreting estradiol and inhibin A. Estradiol stimulates cervix endometrial proliferation and mucus production. A peak in estradiol causes the release of LH, which is responsible for ovulation and the subsequent secretion of progesterone by the corpus luteum, which involutionates 14 days later if not stimulated by hCG (pregnancy). Normal menstrual cycles last 28 days, with a two-day fluctuation in the same woman considered a normal pattern or a regular cycle. The normalcy of these events would allow for successful embryo implantation in the case of trying to conceive. To be fertilized, a capable spermatozoon must reach an adequate ovule during the ovulatory stage. The spermatozoon can survive for up to 5 days in the feminine genital ractum , but the ovum can only be fertilized for 12-24 hours. Fecundation takes place in the distal third of the fallopian tube, and the fecundated zygote develops into a morula before being implanted at the endometrium four days later.

The otter allele is found in Lane 2. To which population does it belong
DNA fingerprints are all the genetic markers used to differentiate individuals or populations. In the exposed example, the otter from lane two belong to population 2, Esther passage, because its band is 890 PB in length.
What is DNA fingerprint?
We can refer to DNA fingerprint as the group of genetic markers that differentiate an individual from another individual, or a population from another population.
Genetic markers are unique DNA fragments that are not identical in all individuals or populations. These fragments provide unique information about the individual or the population, so they are usually used to analyze differences, identify a progenitor, or solve a crime.
DNA prints are used to identify the population origin of an individual, or filial relationships, among others.
In the exposed example, we have DNA samples of 8 individuals belonging to three different populations.
Two alleles are used as markers to identify the individual belonging to each group.
Population 1 ⇒ Unakwik inlet ⇒ 610 and 890 bp band length ⇒ both allelesPopulation 2 ⇒ Esther passage ⇒ 890 bp band length ⇒ one allelePopulation 3 ⇒ Wells bay ⇒ 610 bp band length ⇒ the other alleleTo identify individuals belonging to each group, we just need to count the number of band they express.
In the case of individual number 2 (lane 2), there is only one band. So we can dismiss population 1 (because this population has the two alleles).
The expressed band is approximately 890 pb length. It means that it belongs to population 2, Esther passage.

Different processes can be used by cells to transport lipids, a type of biomolecule. Lipid droplets are specialized organelles that are one method of transporting lipids.
Triacylglycerols, a class of lipids also known as neutral fats, make up the majority of lipid droplets, which are tiny, spherical structures that are found in the cytoplasm of cells. Neutral fats can be stored and transported inside of cells via lipid droplets, which are also involved in their formation and decomposition.
Vesicles having a membrane around them can also be used to transport lipids inside cells. These vesicles, which are tiny, closed containers made of the plasma membrane, are employed by cells to transport a variety of biomolecules, including lipids. Vesicles can be created by the Golgi apparatus, an organelle that is involved in the synthesis and modification of biomolecules, or they can be created by the endocytosis process, in which the plasma membrane invaginates to form a vesicle.

The viral particle entities do not possess the ability to synthesize their own proteins.
A virus doesn't have the propensity to create its own proteins. Although viruses cannot carry out life-sustaining processes or reproduce, they are the classic parasites of the living kingdoms. Viruses are neither animals, plants, or bacteria. Since they lack ribosomes and are therefore unable to make proteins, they must rely on the ribosomes of their host cells to convert viral messenger RNA into viral proteins.
Through the processes of transcription and translation, proteins are created in cells. In essence, the transcription process includes converting the DNA template into mRNA.
