Four of the five answers below are related by a common phase of mitosis. Select the exception. Group of answer choices chromosomes align at the spindle equator sister chromatids become individual chromosomes centromeres divide the chromosomes move apart spindle microtubules shorten, pulling chromosomes toward the poles
Answer:
The correct answer is - chromosomes align at the spindle equator.
Explanation:
Chromosomes move and align at the spindle equator during the metaphase stage of mitosis and other given events take place during the anaphase stage of the mitosis cell division. Metaphase is the second phase of the M-phase of mitosis division whereas anaphase is the third phase.
The metaphase is characterized by the alignment of the chromosomes at the equator whereas the anaphase is separating the chromosomes pulled towards the poles and division of centromeres.

For each - choose either peroxisome or lysosome, both or neither Group of answer choices uses hydrolases lysosome uses the enzyme catalase peroxisome is one of the main sites of fatty acid breakdown peroxisome combines with endosomes to digest ingested matter lysosome capable of converting hydrogen peroxide to water and oxygen peroxisome destroys engulfed bacteria both lysosome and peroxisome main role is metabolism both lysosome and peroxisome digestive interior is acidic lysosome proteins are derived from the endoplasmic reticulum
Answer:
Uses hydrolases -lysosome
Uses the enzyme catalase- peroxisome
Is one of the main sites of fatty acid breakdown- peroxisome
Combines with endosomes to digest ingested matter- lysosome
Capable of converting hydrogen peroxide to water and oxygen- peroxisome
Destroys engulfed bacteria- lysosome
Main role is metabolism- both lysosome and peroxisome
Digestive interior is acidic- lysosome
Proteins are derived from the endoplasmic reticulum- Peroxisome
Explanation:
The lysosome is a membrane-bound organelle found within a cell whose main function is to ensure the break down of biological polymers, such as proteins and polysaccharides. It is comprised of enzymes that are degradative in nature that can degrade biological polymers such as proteins, nucleic acids, lipids, etc. They contain various types of hydrolytic enzymes such as proteases, nucleases, glycosidases, lipases, phospholipases, phosphatases, and sulfatase. These enzymes are acid hydrolases as they function in the acidic environment of the lysosome. Lysosomes are also used by the cell to destroy invading viruses and bacteria.
Peroxisomes are membrane-bound organelles found within the cytoplasm of a cell. They are derived from the edoplasmic reticulum. Peroxisomes are involved in lipid biosynthesis, for example, cholesterol and dolichol are synthesized in peroxisomes. Peroxisomes are also involved in the synthesis of bile acids from cholesterol.
Peroxisomes contain enzymes that oxidize fatty acids and amino acids. Peroxisomes also contain enzymes such as catalase that convert hydrogen peroxide to water and oxygen preventing oxidative damage by these reactive oxygen species.

Indicate whether each of the following statements is true of depurination (DP), deamination (DA), or pyrimidine dimer formation (DF). A given statement may be true of any, all, or none of these processes. This process is caused by spontaneous hydrolysis of a glycosidic bond. This process is induced by ultraviolet light. This can happen to guanine but not to cytosine. This can happen to thymine but not to adenine. This can happen to thymine but not to cytosine. Repair involves a DNA glycosylase. Repair involves an endonuclease. Repair involves DNA ligase. Repair depends on the existence of separate copies of the genetic information in the two strands of the double helix. Repair depends on cleavage of both strands of the double helix.
Answer:
- This process is caused by spontaneous hydrolysis of a glycosidic bond: depurination and deamination
- This process is induced by ultraviolet light: pyrimidine dimer formation
- This can happen to guanine but not to cytosine: depurination
- This can happen to thymine but not to adenine: pyrimidine dimer formation
- This can happen to thymine but not to cytosine: none
- Repair involves a DNA glycosylase: deamination
- Repair involves an endonuclease: depurination, deamination and pyrimidine dimer formation
- Repair involves DNA ligase: depurination, deamination and pyrimidine dimer formation
- Repair depends on the existence of separate copies of the genetic information in the two strands of the double helix: depurination, deamination and pyrimidine dimer formation
- Repair depends on cleavage of both strands of the double helix: none
Explanation:
Depurination is the loss of purine bases (either adenine or guanine), while deamination refers to the removal of an amino group. During depurination, a β-N-glycosidic bond is cleaved by hydrolysis and a nucleic base is released (either adenine or guanine). All DNA bases may undergo deamination, except thymine (since thymine does not have an amino group). The ultraviolet (UV) radiation can cause thymine or cytosine to form dimers (e.g., pyrimidine dimers), being thymine dimers the most common lesion when DNA is exposed to UV light. Pyrimidine dimers may be repaired by different excision mechanisms, e.g., nucleotide excision repair, where the recognition of the DNA damage leads to the removal of the DNA fragment containing the lesion. DNA glycosylases are enzymes involved in the mechanism of base excision, these enzymes recognize and remove damaged bases by hydrolysis of the glycosidic bond, producing an abasic (apurinic and apyrimidinic) site. A DNA ligase enzyme covalently joins two DNA molecules by forming a phosphodiester bond, which is required during these processes.

Answer:
D. Coniferous and Deciduous trees
Explanation:
These trees are found in the humid subtropical climate areas.
Correct on edg. 2020
Coniferous trees grow slow and die old as compared to Deciduous trees.
What do you mean by Coniferous trees?Coniferous trees may be defined as mostly evergreen trees and shrubs having usually needle-shaped or scalelike leaves and including forms with true cones and others with an arillate fruit.
Deciduous trees tend to grow faster than evergreen trees. They have broader leaves as compared to evergreen trees. Coniferous trees have needles instead of leaves. They don't change color in the fall.
Therefore, Coniferous trees grow slow and die old as compared to Deciduous trees.

2. Macromolecules come from Food
3. Catabolic, Anabolic, and Metabolism
What do you mean by metabolism?Metabolism is the set of life-sustaining chemical reactions in organisms. The three main purposes of metabolism are: the conversion of the energy in food to energy available to run cellular processes.
Moreover, it is the process by which the body changes food and drink into energy. During this process, calories in food and drinks mix with oxygen to make the energy the body needs. Even at rest, a body needs energy for all it does.
Hence, if your metabolism is "high" (or fast), you will burn more calories at rest and during activity. A high metabolism means you'll need to take in more calories to maintain your weight. That's one reason why some people can eat more than others without gaining weight.

4. A woman with defective tooth enamel (autosomal recessive) and normal color vision, (X-linked) who had a color blind father with normal tooth enamel and a mother with normal vision and defective tooth enamel, marries a color blind first cousin with normal tooth enamel who had a father with defective tooth enamel. What is the probability of their having a child with normal tooth enamel and color blindness
Answer:
The probability of their having a child with normal tooth enamel and color blindness is 3/8 or 0.375
Explanation:
Let the alleles for normal and defective tooth enamel be T and t respectively.
Color blindness is on the X-Chromosome. Let the allele normal vision and colour blindness be Xn and Xc respectively.
The woman had a colour blind father (XcY) and a normal vision mother, so her allelic pair for vision will be XnXc.
Her father had normal tooth enamel while her mother had a defective tooth enamel, therefore, she will have the allelic pair, Tt.
Her genotype for vision and tooth enamel will be XnXcTt.
Her husband who is color blind with normal tooth enamel had a father with defective tooth enamel, tt. Therefore, her husband's genotype for vision and tooth enamel will be XcYTt.
From the dihybrid cross of XnXcTt and XcYTt, the following offspring are obtained:
XnXcTT, XnXcTt, XnYTT, XnYTt
XnXcTt, XnXctt, XnYTt, XnYtt
XcXcTT, XcXcTt, XcYTT, XcYTt
XcXcTt, XcXctt, XcYTt, XcYtt
From the results of the cross, a child with normal tooth enamel and color blindness will have the following genotypes: XcXcTT, XcXcTt, XcYTT, XcYTt, XcXcTt, XcYTt.
Probability of their having a child with normal tooth enamel and color blindness = 6/16 = 3/8 or 0.375
