Suppose the great, green galoofus lizard has 28 chromosomes in the nucleus of its unfertilized eggs. Predict how many chromosomes will be in the skin cells of a great, green galoofus lizard?
Answers
Answer: 56
Explanation:
Because an unfertilized egg has half the chromosomes of a fertilized egg. The fertilized egg then splits, and continues splitting until the lizard is born. Always remember, whenever a question talking about an unfertilized egg, it has half the chromosomes of a fertilized egg. One more side note, it doesn’t matter what body part you talk about. A skin cell will have the same number, and identical chromosomes compared to a heart cell. (So long as it’s the same organism, if it isn’t, but part of the same species, it will have the same number of chromosomes, but it may have a unique set of chromosomes). If you want me to go into detail, I can, just respond to this answer.

Answers
An active site is the area at where the enzyme gets attached. The are labelled X is known as an active site.The correct answer is option B.
What is an atomic nucleus ?An atomic nucleus is the central region of the atom at which the number of protons and neutrons are in abundance. The charge carried by the nucleus is positive in nature.
The picture shows the lock and key method where it is the relation between enzyme and substrate where the enzyme and substrate are almost same in shape where the lock is the substrate where the enzyme is of key shaped and they both fit in.
An active site is the region of the reactant or substrate where the enzyme will bind in and the reaction will form a product. The binding of both the constituents depend on the binding energy and activation energy of the reaction.

Epithelial tissue one most important type of tissue.
It can be up two types such as Simple epithelium and Stratified epithelium.
Simple epithelium is a single layer of identical cells, observed at sites of secretion, absorption of substances.
It can be up three types Squamous epithelium, Cuboidal epithelium, Columnar epithelium.
Simple Squamous epithelium is single layer of flattened cells found Lungs-alveoli, Blood vessels-endothelium.
Simple cuboidal epithelium found in tubules of nephrons and glands which is involved secretion, absorption, and excretion, etc.
Simple columnar epithelium found in the inner layers of the stomach, intestine, trachea,
Stratified epithelium which is multiple layers epithelial tissue can be up 4 types squamous, cuboidal, columnar, Psuedo-stratified columnar epithelium.

what changes will occur in the patients cells ?
what can be done to fix this problem ?
Answers
Answer:
The patient's cells will swell and then burst. The solute concentration outside the cell is lower than inside the cell, so water will move into the cells.
Mike would have to give the patient a hypertonic solution, which will cause water to move out of the cell and the cell to shrink followed by an isotonic solution, which should regulate the concentration inside and outside the cell.

If a DNA strand has 32 % guanine, what percent thymine does it contain?
A) 36%
B)18%
C)64%
D)32%
Answers
Answer:
B
Explanation:
Guanine and Cytosine pair together. So, if 32 percent is guanine, then 32 percent should also be cytosine. This is a total of 64 percent. The remaining 36 percent is split between thymine and adenine. So, Thymine will have half of 36 percent which is 18 percent.

Answers
Answer:
Euphotic zone is the layer closer to the surface that receives enough light for photosynthesis to occur. Beneath lies the disphotic zone, which is illuminated but so poorly that rates of respiration exceed those of photosynthesis.
Bathyal zone is the part of the pelagic zone that extends from a depth of 1000 to 4000 metres below the ocean surface. It lies between the mesopelagic above, and the abyssopelagic below.It is ala known as midnight zone.

Binding the RNA polymerase to the gene
Preventing the repressor from binding to the lac operon
Removing the inducer
Transcribing the lacl sequence
Answers
Answer:
Transcribing the lacl sequence
Explanation:
lacZ, lacY, and lacA sequences are the structural genes, which needs to be expressed in order to produce their proteinous enzymes required for the breaking down of lactose sugar. The transcription of these three genes must occur with the aid of RNA polymerase binding to them.
However, a gene sequence called lacI encodes information for an repressor, which when expressed can inhibit the expression of the genes lacZ, lacY, and lacA. Hence, the TRANSCRIPTION OF THE LACL SEQUENCE cause the cell to not express the lacZ, lacY, and lacA sequences.
Answer: removing the inducer
Explanation: all sequences need an inducer present in order for them to be expressed
