Answer:
Prometaphase (late prophase)
Explanation:
Mitosis is the kind of cell division in which two genetically identical copies of a cell is formed from a cell. Mitosis comprises of stages which include prophase, metaphase, anaphase and telophase. Each phase is characterized by specific occurrences that all work together to achieve the main goal of forming two daughter cells.
According to this question, PROPHASE stage is the stage characterized by the condensation of chromatids into chromosomes, the disappearance of nucleolus and BREAKDOWN of NUCLEAR MEMBRANE.
A cluster of cases of legionellosis have occurred in your neighborhood. People with the illness have cough, fever, shortness of breath, chest pain and sometimes diarrhea. The illness is caused by the bacterium Legionella pneumophila, a facultative intracellular parasite that survives in certain ameba. The organism has an absolute requirement for L-cysteine. Typically, the organism is grown on buffered charcoal yeast extract (BCYE) agar. In some labs, samples containing suspected L. pneumophila are cultured on traditional BCYE medium as well as BCYE medium lacking L-cysteine. How would L. pneumohila be identified in this situation
Answer:
The correct answer is - comparing the presence of an essential component of the L. pneumophila that is cysteine.
Explanation:
As we know that L-cysteine is essential for the organism L. pneumophila to grow its colonies. The identification is easy in this situation by comparing the two cultured on the traditional BCYE medium and BCYE medicum without L-cysteine.
Colonies that grow on traditional BYCE medium are likely L. pneumophila as they required L-cysteine but not on BYCE medium lacking cysteine.

When you flex your knee, where are the fulcrum and the load? Where is the muscle that provides the effort located?
Explanation:
the fulcrum is the knee joint
the load is probably the radius and ulna with the muscle on it
while the effort could be tendons and the muscle on the femur
PLEASE HELP!!!!
Explain what causes a muscle to go into rigor mortis. Your answer should include the circumstances which cause it, as well as why those circumstances cause the effect (what is happening in the muscle at a molecular level which causes the stiffness).
Explanation:
Rigor mortis develops as the body's energy source (adenosine triphosphate [ATP]) is depleted. Muscle fibers require ATP for relaxation; once depleted, actin and myosin proteins remain complexed, resulting in stiffening of the muscles..

6. Explain how sunken stomata lower the rate of transpiration

with
ftri
Answer:
Due to stomata.
Explanation:
Transpiration occurs mainly through leaves because of the presence of stomata n the lower side of the leaves. Transpiration refers to the loss of water from the body of plants so leaves has small pores which is used by the plant to regulate internal temperature. Sunken stomata lower the rate of transpiration because it is not directly exposed to the surface which protects the escaping water vapor due to air.

The first stage of the cell cycle during which the cell matures and prepares to divide and copies
its DNA; The stage the cell stays in the most?
The cell multiplies and creates a copy of its DNA during interphase. In the mitotic (M) phase, the cell divides into two new cells by dividing its cytoplasm and DNA into two sets.
What is the main role of interphase stage of cell cycle?A cell consumes the bulk of its time in what is known as interphase, where it creates, duplicates its chromosomes, and acquires available to split. The cell then moves interphase, goes direct mitosis, and completes dividing.
The cell multiplies and the nuclear DNA is duplicated during interphase. The mitotic phase immediately follows interphase.
Chromosomes that have been duplicated are separated and distributed across daughter nuclei during the mitotic phase. Usually, the cytoplasm is divided as well, producing two daughter cells.
Therefore, The first stage and the stage the cell stays in most is Interphase.

A. Identifying the rock as either intrusive or extrusive
B. Observing the color of the rock based on minerals
C. Knowing the additional minerals found in the rock
D. Determining the amount of pyroxene in the rock
In a separate study, 68 rock pocket mice were collected from four different, widely separated areas of dark lava rock. One collecting site was in Sonora, Mexico. The other three were in Chihuahua, Mexico. Dr. Nachman and colleagues observed no significant differences in the color of the rocks in the four locations sampled. However, the dark-colored mice from the three Chihuahua locations were slightly darker than the dark-colored mice from the Sonora population. The entire Mc1r gene was sequenced in all 68 of the mice collected. The mutations responsible for the dark fur color in the Sonora mice were absent from the three different populations of Chihuahua mice. No Mc1r mutations were associated with dark fur color in the Chihuahua populations. These findings suggest that adaptive dark coloration has occurred at least twice in the rock pocket mouse and that these similar phenotypic changes have different genetic bases.

How does this study support the concept that natural selection is not random?
Answer:
The study supports the concept that natural selection is not random because in different areas with the same or very similar environmental characteristics, the same phenotype was produced by different types of mutations.
Explanation:
All of the sampled animals are inhabiting dark substrate. Probably animals needed to camouflage to survive. Natural selection must have driven them to produce dark color, similar to the substrate color. So animals from the different regions suffered different mutations that drove them to have almost the same dark fur color. The environmental condition is favoring the same phenotype.

What is body systems and their interaction?There are numerous parts to the human body. Every physical portion serves a distinct purpose. To better comprehend how the human body's components interact with one another and work together as a whole, scientists divide the body into systems. A group of bodily parts that cooperate to carry out a specific task is known as a body system.
For instance, the integumentary system, that shields the body from its surroundings, is made up of the skin, hair, and nails. Another instance of an organ that guards the body is the immune system.
