Answer:
There are three types of endocrine cells;
Explanation:
; alpha cells which secrete glucagon, beta cells which secrete insulin, and delta cells which inhibit the secretion on glucagon and insulin: Glucagon increases the blood glucose level by stimulating the liver causing convert Glycogen into Glucose (sugar).
Answer:
10. View the slides on the PowerPoint to match each of the cell structures with the correct letter labels for
each of the following cells.
Elodea Cell Cell wall _B____ Chloroplast _A___ Area of vacuole _C__ Onion Cell Cell wall _B__ Nucleus __A_ Mitochondria _C__ Cheek Epithelial Cell Cell membrane _B__ Nucleus __A_ BacteriA Bacterial Cells. View the bacterial cells on the PowerPoint and identify which cell (A, B, or C) is: Coccus ________B____ Bacillus ______A______ Spirillum ______C______ Protista Amoeba can move via the extension of finger-like projections called pseudopodia
Explanation:
Amoeba can move via the extension of finger-like projections called pseudopodia, what prevents plant cells from moving in the same fashion?
Ans: The plants that prevent the information of pseudopodia have rigid cell walls. which is unlike to amoeba.
How does the euglena compare to both plant and animal cells (i.e. - explain what structure(s) might make it similar to plants and what structures might make it similar to animals).
Ans: Euglena are similar to plants because they both have chloroplast and are similar to animals because neither has a cell wall.
Answer:
Explanation:
The electron-carrier proteins are arranged in the inner mitochondrial wall. A dehydrogenase enzyme (think of it as the first protein of the electron-transport chain) oxidises NADH2 (which is the reduced coenzyme NAD) and/or FADH2 (reduced coenzyme FAD). The energy from the oxidation process is used to pump hydrogen ions from the matrix to the inter-membrane space of the mitochondrion. Because of this, gradient of hydrogen ion concentration builds up across the inner mitochondrial membrane, which generates a potential difference across the membrane. The protons then flow back to the matrix through an enzyme called ATP synthase (also called ATPase). (This is called chemiosmosis because a chemical substance (H+) moves across a membrane, down the concentration gradient.) This releases energy needed for the ATP synthase to phosphorylate ADP, i.e. make ATP (chemical energy for use in the cell) from ADP and inorganic phosphate.
Note: Bolded things are important, everything else is just additional clarification in case you need it. This is the last major phase of cellular respiration. If you want a deeper insight into the process, I suggest you read a bit about glycolysis and Krebs cycle.
Answer:
A. Dominant alleles often encode functional products, whereas recessive alleles often do not encode functional products
Explanation:
One gene can have it's variant forms called allele but in one individual only two allele form of a gene can be present. These two allele form can be the same(homozygous) or different(heterozygous). A dominant allele often encode a function protein of product while recessive allele often code for non- functional product.
Therefore when the dominant allele is present in the chromosome then function products are formed which can be seen in the phenotype and even a single dominant allele produce the functional product like in heterozygous condition so phenotype in heterozygous and homozygous dominant condition appears same. So the correct answer is A.
