Answer: C. 9
Explanation:
Gestation refers to the time between when a baby is conceived till the baby is delivered. This is why the period of pregnancy is known as the Gestation Period.
During that time and after the fertilized egg implants itself in the uterus, the baby develops and grows until it is ready to be delivered.
The structure this occurs in is the uterus (womb) which is labelled 9 in the structure above.

Have you ever noticed that aside from zoos, you don't see kangaroos, wombats, and koala bears outside of Australia? This is because there is a trench that is a "biogeographical transition zone between Asian and Australian flora and fauna". What is the name of that trench?
Answers
Answer:
Wallace Line
Explanation:
Wallace Line is a boundary line which is a transitional zone between Asia and Australia. This boundary drawn by the British naturalist Alfred Russel Wallace in 1859. This boundary restricts the transferring organisms such as flora and fauna from Australia to Asia. So that's why kangaroos, wombats, and koala bears are only present in Australia not in the continent of Asia.

In most organisms, the end product of glycolysis is pyruvate. Pyruvate still contains a substantial amount of energy, which can be further extracted. Whether the organisms are operating under aerobic or anaerobic conditions determines the metabolic pathway that pyruvate undergoes to produce more ATP. In this tutorial, you will identify the end products of these metabolic pathways.
Answers
Answer:
Pyruvate helps in the production of ATP.
Explanation:
The molecule of pyruvate converted into acetyl CoA. Then each molecule which is produced during glycolysis loses electron and carbondioxide releases. After the breakdown of pyruvate, the electrons loses by pyruvate are transferred to NAD+ in order to produce NADH, which will be used by the cell to produce energy molecule such as ATP. So we can say that pyruvate plays a vital role in the formation of ATP molecule.

Do the spinal nerves include the sensory or motor neurons? Where do these neurons enter or exit the spinal cord?
Answers
Answer:
hd
Explanation:
The spinal nerves include the sensory or motor neurons sensory neuron → brain → motor neuron → muscles.
What are neurons?Neurons are nerve cells that are specialized to process and transmit information. The brain then processes the information obtained from the sensory neuron and sends another signal trough the motor neuron carrying the message to the muscle.
The spinal cord acts as a nerve center between the brain and the rest of our body and it contains motor neurons that transmits nerve signals from the motor cortex to the body, and the spinal cord also receives all of the sensory information from the periphery of our bodies.
Motor neurons are also known as efferent neurons, they are part of the central nervous system that transmit impulses from the brain or spinal cord to the effector organ (muscles or glands).
Therefore, The spinal nerves include the sensory or motor neurons sensory neuron → brain → motor neuron → muscles.

Required:
a. Why is this the case?
b. Name ONE signal transduction pathway that hormone X is using to transfuse its signal. (write all the steps and intermediates)
Answers
Answer:
a. It is a hormone that acts upstream in the signaling pathway (i.e., acting as a ligand by binding to cell receptors)
b. Dopamine-mediated pathways
Explanation:
It is well known that many cellular transduction pathways are activated via binding of signaling molecules (ligands) to receptors capable of triggering signaling cascades into the cell. For example, dopamine is a signaling hormone (neurotransmitter) involved in diverse brain processes (i.e., motor control, emotional response, etc). It is a neurotransmitter that binds to dopamine receptors and then stimulates the enzyme adenylate cyclase in a process that subsequently activates the production of the second messenger cyclic adenosine monophosphate (cAMP). Finally, cAMP acts as an intracellular signal transductor that play roles in many biological processes by transferring into the cell the effects of dopamine.
You are observing a sample of cells in the lab to determine why they did not
divide properly. You notice that the chromosomes are lined up in the middle
of the cell, and the spindle fibers have extended towards them, but have not
attached. What could be damaged?
Answers
Explanation:
What could be damaged that is hindering the spindle fibers from attaching to the chromosomes are the kinetochores of the chromosomes.
At the metaphase stage of the cell division, the chromosomes align at the equator of the cell and the spindle fibers engage each chromosome at a region known as the kinetochore.
The kinetochore is made up of complex proteins and lies around the centromere region of the chromosome. The microtubules of the spindle fibers attach to this region during the metaphase stage.
If the kinetochore is damaged, it means the spindle fiber will not be able to attach to the chromosome.

Answers
Answer:
Explanation: Ependymal cell is a type of neuronal support cell the forms the epithelial lining of the brain ventricles in the brain and the central canal of the spinal cord ependymal cells similar to all other neuroglia, are derived from a layer of embryonic tissue known as neuroectoderm.
Ependymal cells are ciliated-epithelial glial cells. It develops from radial glia alongside the surface of the ventricles of the brain and spinal canal.
What is the function of Ependymal cells?The main role of Ependymal cells is formation of CSF.
The CSF refers to cerebrospinal fluid. It is done by movement of sodium ion, chlorine ion and bicarbonate ion from blood to ventricles of brain.
Inside ventricles of the brain, collection of ependymal cells and capillaries together i.e., the tela choroidea form choroid plexus, which produces the CSF.
Thus, Ependymal cells are involved in formation of CSF.

Design a controlled experiment to test the effect of water temperature on goldfish. be sure to include your hypothesis, independent variable, dependent variable as well as experimental group and control group.
Answers
Answer:
In this experiment, indepedent variable will be temperature and dependent variable will be the respiratory rate of goldfish. Temperature affects the respiratory rate of goldfish, as it's respiratory rate decreases with decrease in temperature of water, the experiment is as follows:
Take two glass containers filled with water A and B and put one goldfish in each container.Measure the temperature of the water using a thermometer.Count mouth movement of both the fishes in certain time.Now put some ice in container B that will decrease the temperature of water and measure the temperature again.Now count the mouth movement of both the fishes for the same time it was counted earlier.The result will be that respiratory rate of goldfish decreases with the decrease in temperature in container B in comparison to container A goldfish.
An experiment meant to determine the cause of an effect, the effect is the independent variable, while the cause is the dependent variable
A controlled experiment to test the effect of water temperature on goldfish is designed as follows:
The experimental group are: The gold fish in a glass Jar X filled with fresh water and with the lid left open (the treatment of temperature reduction is applied to the experimental group)
The control group are: A second gold fish (selected at random) of the same size, in another glass jar Y filled to the same level with fresh water collected from the same source of the first gold fish
Independent variable: The independent variable is the temperature of the water which will be varied by placing ice cube gradually into the glass jar B
Dependent variable: The number times the gold fish gulp air by rising to the surface, and or the number of time goldfish opens its mouth, which indicates that the goldfish is breathing
The hypothesis: The breath rate of goldfish decreases with decrease in temperature because the goldfish metabolic rate decreases and the water holds more dissolved air and therefore oxygen at a reduced temperature
The Experiment Design:
The experiment is conducted by measuring the initial temperature and breathing rate of both fishes
The temperature of the fresh water in jar X is decreased gradually by adding ice cubes and recording the temperature and breathing rate of the goldfish
A similar experiment from an online source (Maryland School improvement website) the following results where obtained
[tex]\begin{array}{|c|cc|} \underline {Breathing \ rate}&&\underline {Water \ Temperature } \\&&\\ (Dependent \ Variable)&&(Independent \ Variable)\ \\&&\\103&&78.8 ^{\circ}F\\78&&68^{\circ}F\\55&&57.2^{\circ}F\\28&&46.4^{\circ}F\\4&&35.6^{\circ}F\end{array}\right][/tex]
From the experiment, it can be seen that the in the experimental group dependent variable, which is the breathing rate of the goldfish reduces as the temperature which is the dependent variable is reduced

A growth medium or culture medium is a solid, liquid or semi-solid designed to support the growth of a population of microorganisms or cells via the process of cell proliferation,[1] or small plants like the moss Physcomitrella patens.[2] Different types of media are used for growing different types of cells.[3]
The two major types of growth media are those used for cell culture, which use specific cell types derived from plants or animals, and microbiological culture, which are used for growing microorganisms, such as bacteria or fungi. The most common growth media for microorganisms are nutrient broths and agar plates; specialized media are sometimes required for microorganism and cell culture growth.[1] Some organisms, termed fastidious organisms, require specialized environments due to complex nutritional requirements. Viruses, for example, are obligate intracellular parasites and require a growth medium containing living cells.
