Please choose the answer that best completes the blanks of this sentence in the correct order. The ______ plate method involves spreading an inoculum onto the surface of a plate in a pattern that results in isolated colonies in some areas of the plate after incubation, whereas the ______ plate method involves diluting an inoculum into several melted agar tubes and then adding their contents into plates for solidification and incubation.
Answer:
streak, pour
Explanation:
The streak method is the most popular technique used to isolate specific bacteria from a sample containing different microorganisms. In this technique, a sterile loop is employed to obtain an uncontaminated microbial culture. Colony picking refers to the process where colonies of pure bacteria are selected in order to duplicate them by transferring them into new agar plates. Moreover, the pour plate method is the most popular technique employed to count the number of colony-forming bacteria (i.e., bacteria/ml) in a specimen. The pour plate method consists of dropping the sample on a sterile plate and subsequently molten-cooled agar is then poured into the plate and mixed well with the inoculum.
Answer:
streak, pour
Explanation:
The streak plate method involves spreading an inoculum onto the surface of a plate in a pattern that results in isolated colonies in some areas of the plate after incubation, whereas the pour plate method involves diluting an inoculum into several melted agar tubes and then adding their contents into plates for solidification and incubation.

Facilitated diffusion requires
A. a protein pump, energy, and a concentration gradient.
B. no energy, net osmotic movement, and a protein pump.
C. a concentration gradient, a protein channel, and no energy.
Answer:
A.Explanation:
TutorialDiffusionDiffusion means that the net movement of particles (molecules) is from an area of high concentration to low concentration.Graph of the simple and facilitated diffusion taking into account the rate of uptake and the concentrationIf the particles can move through the lipid bilayer by simple diffusion, then there is no limit to the number that can fit through the membrane. The rate of diffusion increases linearly as we add more particles to one side of the membrane.If the particles can only pass through protein channels, then the rate of diffusion is determined by the number of channels as well as the number of particles.Once the channels operate at their maximal rate, a further increase in particle numbers no longer increases the apparent rate of diffusion. At this limited rate we describe the protein channel as being saturated.The cartoon illustrates several points about facilitated diffusion. The particles are more concentrated on one side of the membrane, and yet they can move in both directions. However, the net movement is from high particle concentration to low. If the number of particles gets so high on one side of the membrane that they interfere with diffusion through the protein channel, then we observe a limit to the rate of diffusion at the point of saturation.Illustration of facilitated diffusionanimation used with permission of the Virtual Cell Web PageProblem 7 | Answer | Problem 8The Biology Project > Cell Biology > Cell Membranes > Problem SetThe Biology ProjectDepartment of Biochemistry and Molecular BiophysicsUniversity of ArizonaMay 2002Revised: August 2004Contact the Development TeamSimple diffusion does not require energy: facilitated diffusion requires a source of ATP. Simple diffusion can only move material in the direction of a concentration gradient; facilitated diffusion moves materials with and against a concertion gradient.
Answer:
C. a concentration gradient, a protein channel, and no energy.
Explanation:
Facilitated diffusion requires a concentration gradient, a protein channel, and no energy.

Select the correct answer. Which form of birth control could people use without altering hormonal systems or blocking sperm from fertilizing an egg
Answer:
Fertility awareness
Explanation:
Fertility awareness involves the woman being observant about different pointers during her menstrual cycle. This method is not the safest.
Studies have shown that a woman is less likely to get pregnant few days after completing her menstruation but very fertile around 12-14 days before her next period comes up.
This form of birth control doesn’t involve altering hormonal systems or blocking sperm from fertilizing an egg

The selective serotonin uptake inhibitors, like the antidepressants Prozac, Zoloft, or Paxil, result in increased levels of serotonin at synapses, which may _____ initially but then lead to _____.
Answer:
increase anxiety; decreased vulnerability to overreact to stress
Explanation:
Serotonin (5-HT) is a natural neurotransmitter that carries signals between nerve cells (neurons) throughout the body. This neurotransmitter (serotonin) is responsible for regulating many biological functions (e.g., mood, digestion, sleep, etc). Moreover, it has been shown that there is an association between low cerebrospinal fluid 5-hydroxyindole-acetic acid (5-HIAA, the principal serotonin metabolite in the brain) levels and the risk of developing depression or destructive behaviors. In addition, serotonin concentration can also be elevated in situations of anxiety and/or stress. Antidepressants such as Prozac, Zoloft and Paxil act as serotonin uptake inhibitors that increase serotonin concentration at the synaptic site. Like other drugs, these antidepressants may lead to increase anxiety and decrease the vulnerability to react to stress by downregulating sensitivity to serotonin released during natural stress situations.

Nucleusb) The watery fluid that surrounds the nucleus of the cell and is needed for growth, reproduction, and self-repair 3. Cytoplasm c) The process of cell reproduction of human tissues that occurs when the cell divides into two identical cells 4. Cell membrane d) The part of the cell that encloses the protoplasm and permits soluble substances to enter and leave the cell
Answer:
1. Mitosis c) The process of cell reproduction of human tissues that occurs when the cell divides into two identical cells
2. Nucleus a) The dense, active protoplasm found in the center of the cell
3. Cytoplasm b) The watery fluid that surrounds the nucleus of the cell and is needed for growth, reproduction, and self-repair
4. Cell membrane d) The part of the cell that encloses the protoplasm and permits soluble substances to enter and leave the cell
Explanation:
Mitosis is the process that undergoes a cell to give two new identical cells. This is how our body makes or renovates tissues.The nucleus is the part of the cell that contains the DNA, which is necessary to synthesize the proteins that the cell and our body need. It is in the center of the cell and has a nuclear membrane that separates it from the rest of the organelles.The cytoplasm is a solution that surrounds the nucleus, and it contains the rest of the organelles that the cell needs for its functions. The cell membrane is the structure that encloses all the cytoplasm and the nucleus. It is made of phospholipids, proteins, and cholesterol, which allows the passage of certain substances.will mark brainlist, help please!

Highly toxic chemicals that persist in the environment have been associated with disruption of the: immune system. reproductive system. nervous system. All of these are correct.
Answer:
All of these are correct.
Explanation:
Immune system, reproductive system and nervous system are adversely affected by the contact of highly toxic chemicals because toxic chemicals have materials which is harmful for the cells that the cause of cell death or damaged the structure of the cell due to which the cell can't perform its function efficiently. All the system i.e. Immune system, reproductive system and nervous system are made up of cells so if the cells are damaged by these toxic chemicals the body systems are also negatively affected.
