The correct answer is B. Insects

Explanation:

The American Board of Forensic Entomologists or ABFE is an organization in the U.S. that offers certifications to Forensic Entomologists. On the other hand, Forensic Entomology is a field related to both criminology and biology that focuses on studying insects in relation to crime scenes or decomposition. Considering Entomology is the study of insects while Forensic science focuses on criminal investigation. For example, through Forensic Entomology it is possible to determine when a person died based on the presence of insects. According to this, the American Board of Forensic Entomologists certifies scientists who study insects in the criminal context.

Meiosis Foldable Activity 515.2

Aleksandr-060686 [28]

Explanation:

During the process of prophase I, the nuclear envelope containing chromosomes has only partly broken down homologous chromosomes are joined together by proteins and a complex or pairing call synapsis- corresponding genes on sister chromatids are aligned precisely.

The syanapsis allows for crossing over which is the exchange of segments of chromosome, between non-sister homologous or similar chromatids crossing over happens at chiasmata, the point where non-sister chromosomes are joined.

Further Explanation:

All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly wound around histones as chromosomes. In meiosis, the number of chromosomes (2n) is halved to 23 chromosomes (haploid number)through meiotic divisions, producing 4 haploid (n) germ cells or gametes (sperm or eggs), each containing half the number of chromosomes as its parent cell.

In Meiosis I

homologs pair off into bivalents
At crossing over: the exchange of segments of chromosome, between non-sister homologous or similar chromatids crossing over happens at chiasmata, the point where non-sister chromosomes are joined in prophase I forming bivalents; tetrads are formed.
Spindle fibers from centrioles join sister chromatids together at their centromeres in metaphase I, pulling them to the equator of the cell;
then, in anaphase I, while joined, they are pulled to opposite sides of the cell; the cell body splits and the nuclear envelope reforms in telophase I

In Meiosis II...

Later, in prophase II, the nuclear envelope disintegrates and mitotic spindle fibers are formed
independent assortment occurs. in metaphase II of meiosis: spindle fibers attach to centromeres, chromatids align independently at the equator. Genes segregate independently into new combinations as sister chromatids are pulled apart by their centromeres in anaphase II
in telophase II the cells' nuclei and membrane are then formed with each containing the haploid number (n)
Following the formation of gametes in the last stage, randomized fertilization occurs in sexual reproduction sperm cells fertilize an ovum to form a zygote. This occurs randomly by chance, to result in a complete set of chromosomes 2n, that is a novel combination of half each parent's number of chromosomes

In response to a stimulus, the membrane slowly depolarizes until the membrane potential reaches a particular value, called thres

Leni [432]

Answer:

The Question is incomplete. Here should be the complete question.

Based on what you have learned about how cells ensure that proteins end up in the right place (Chapter 7), what type of signal would you expect to be exposed on a cytosolic receptor after a steroid hormone changes the receptor's conformation?

Amino acids required for transport through the nuclear pore complex

Initiating an action potential

Under most circumstances, once an axon's membrane potential reaches threshold (about -55 mV in mammals), an action potential is automatically triggered. The graph below shows the changes in membrane potential that occur in an axon membrane that is initially at resting potential.

In response to a stimulus, the membrane slowly depolarizes until the membrane potential reaches a particular value, called threshold. At threshold, a rapid depolarization of the membrane occurs and an action potential is initiated.

Drag the labels onto the flowchart to show the sequence of events that occurs once

the membrane potential

-1. membrane potential reaches threshold

-2. Na+ ions rush into the cell

-3. membrane potential rises (depolarizes) rapidly

-4. many Na+ voltage-gated channels open

The ANSWER WILL SURELY BE

membrane potential reaches threshold ---> many Na+ voltage-gated channels open ---> Na+ ions rush into the cell ---> membrane potential rises (depolarizes) rapidly

(1--->4--->2--->3)
