CONCLUSIONS: Genetic counseling is useful in predicting the probability of a child being born with a Mendelian inherited trait. Sickle cell anemia is caused by a recessive allele. A couple would like to know the chances of their child having sickle cell anemia. Parent #2 has the disease; parent #1 does not. Based on phenotype, parent #2 would have the genotype, ss. Parent #1 could be genotype, SS or Ss. Punnett Squares have been set up for crosses using both possible genotypes of parent #1. Should the couple be concerned that their child may have sickle cell disease? Why or why not?
Answer:
Yes, if parent 1 is Ss then there is a 50% chance the child will have it.

Neurons, as with other excitable cells in the body, have two major physiological properties: ____________ and ____________. A neuron has a positive charge on the outer surface of the cell membrane due in part to the action of an active transport system called the ____________. This system moves ____________ out of the cell and ____________ into the cell. The inside of the cell membrane is negative, not only due to the active transport system but also because of ____________, which remain negative due to the intracellular pH and keep the inside of the cell membrane negative.
Answer:
Neurons, as with other excitable cells in the body, have two major physiological properties: irritability and conductivity. A neuron has a positive charge on the outer surface of the cell membrane due in part to the action of an active transport system called the sodium potassium pump. This system moves sodium (Na+) out of the cell and potassium (K+) into the cell. The inside of the cell membrane is negative, not only due to the active transport system but also because of intracellular proteins, which remain negative due to the intracellular pH and keep the inside of the cell membrane negative.
Explanation:
Neurons are cells with the capacity to transmit information between one another and also with other tissues in the body. This information is transmitted thanks to the release of substances called neurotransmitters, and this transmission is possible due to the electrical properties of the neurons.
For the neurons (and other excitable cells, such as cardiac muscle cells) to be capable of conducting the changes in their membranes' voltages, they need to have a resting membrane potential, which consists of a specific voltage that is given because of the electrical nature of both the inside and the outside of the cell. The inside of the cell is negatively charged, while the outside is positively charged - this is what generates the resting membrane potential. When the membrane voltage changes because the inside of the cell is becoming less negative, the neuron is being excited and - if this excitation reaches a threshold - an action potential will be fired. But how does the voltage changes? This happens because the distribution of ions in the intracellular and extracellular fluids is very dissimilar and when the sodium channels in the cell membrane are opened (because of an external stimulus), sodium enters the cell rapidly to balance out the difference in this ion concentration. The sudden influx of this positively-charged ion is what makes the inside of the neuron become less negative. This event is called depolarization of the membrane.

Which statement best explains the relationship between producer and consumers in terms of
energy?
A. Consumer produce glucose that producer's use for energy B. Consumers convert carbon dioxide into energy
C. Consumers provide energy for producer to undergo aerobic respiration
D. Consumers convert glucose from producers into ATP
please only reply if you know the answer
Answer:
> Consumers convert glucose from producers into ATP.
Explanation:
Consumers do NOT provide oxygen or glucose for producers.
The statement, consumers convert the glucose from producers into ATP. So the correct option is D.
What are producers and consumers?In feeding chains, organisms are categorized into trophic levels. Producers (first trophic level), consumers (second, third, and fourth trophic levels), and decomposers roughly correspond to these levels.
Autotrophs, another name for producers, grow their own food. Every food chain's first level is comprised of these. Plants or single-celled creatures represent the majority of autotrophs. The majority of autotrophs produce their "food" (a nutrient called glucose) from sunlight, carbon dioxide, and water through a process known as photosynthesis.
The most well-known form of autotroph is a plant, but there are numerous others as well. Algae are autotrophic, and their bigger forms are known as seaweed. Autotrophs include the small sea life known as phytoplankton. Autotrophic bacteria include certain varieties. For instance, microorganisms that live in volcanoes that are still active utilize sulfur compounds to make their own food. Chemosynthesis is the name of this process.
Therefore the correct option is D.

briefly explain the relationship between cells, organs and tissues
Answer/Explanation:
Cells of a similar type are organized together to make tissues. Different types of tisues come together to perform a similar function as part of organs.
For example, take the organ the stomach. There are various tissues that make up the stomach, including, for example, mucosa, and muscle tissue.
The mucosa tissue of the stomach is made up of secretory cells such as parietal cells, which secrete hydrochloric acid, and foveolar cells which produce mucus that protects the lining of the stomach.

Color of Starch solution It was a whitish color. Dark, purple, black color. inside bag!Color of Iodine solution A golden color. A transparent creme inside beaker color. Color of starch solution White White inside bag! Color of H20 in beaker TransparentExplanation: Conclusion
The conclusion to this test is that the plastic bag is permeable to iodine. The result
of this experiment clearly answers the "Problem" as stated above. This is~ by
the fact that the starch solution (dependent variable) in the baggie turned purple,
indicating the presence of iodine (independent variable) in the mixture. The starch
solution is the dependent variable because its color is affected by the iodine
solution. M.y hypothesis was that the iodine will get into the bag of starch because
the baggie is permeable to iodine. If the iodine solution penetrates the bag, it will
turn the starch solution inside the baggie, purple. The control data chart above
shows that if the starch had not been immersed in the iodine solution, but rather a
water solution, it would have remained the same color, white. Obviously, in order
for the iodine to enter the starch solution, the baggie must be permeable to the
iodine. The baggie represents a cell membrane. This lab is meant to demonstrate
whether or not a cell membrane is permeable to substances. Cell membranes of
living organisms may be permeable to some substances, but not permeable to other
substances. In this experiment,'1..charted that the iodine solution in the beaker did
not turn purple. This means that the starch solution did not penetrate the baggie
and therefore did not mix with the iodine outside the baggie. Because of this data, it
is clear that the plastic baggie is not permeable to starch, but is permeable to iodine.
In a cell membrane, this is called selective permeability. In other words, the iodine
can go through the baggie, but the starch cannot. The purpose of this experiment is
to show that a cell membrane is a type of barrier, and is permeable to some
substances, but may not be permeable to all substances. Therefore, a cell membrane
is selectively permeable.
