Determine whether each statement describes mitosis, meiosis, or both mitosis and meiosis.
Answer:
DNA replicates in both mitosis and meiosis, Mitosis occurs during growth and development, In meiosis the number of chromosomes reduce by half, Mitosis occurs in all organisms, Meiosis occurs in organisms that sexually reproduce, and chromosomes stay the same in Mitosis.
Explanation:
Mitosis: Occurs during growth and development, Occurs in all organisms, and The number of chromosomes remains the same
Meosis: The number of chromosomes reduces by half, and Occurs in organisms that sexually reproduce
Both: The DNA is replicated.
1. The DNA is replicated: Both Mitosis and Meiosis. In both processes, DNA replication occurs before the division of cells, ensuring that each daughter cell receives a complete set of genetic information.
2. Occurs during growth and development: Mitosis is the process responsible for the growth, repair, and development of multicellular organisms by producing identical daughter cells.
3. The number of chromosomes reduces by half: Meiosis involves two divisions that result in the reduction of chromosome number by half, leading to the formation of gametes (sperm and egg cells) with half the usual number of chromosomes.
4. Occurs in all organisms: Mitosis is a fundamental process occurring in various organisms, ranging from unicellular to multicellular, for growth, tissue maintenance, and asexual reproduction.
5. The number of chromosomes remains the same: In mitosis, the daughter cells have the same number of chromosomes as the parent cell, maintaining the chromosome count.
6. Occurs in organisms that sexually reproduce: Meiosis is specific to organisms that reproduce sexually, as it produces genetically diverse gametes that contribute to the variability of offspring.

why is there no enzyme to digest vitamins
Answer:
Vitamins are used in their original form by the cells. They are either water soluble or fat soluble, hence no enzyme is required to digest vitamins. They are absorbed directly from the digestive tract, transported by blood to the cells, and the cells absorb and use them whenever they need.
The suncoast tree of northwest Africa is known for 2 traits that are said to show simple dominance. The 2 traits are height and bark color. In height, tall is dominant to short, and in bark color blue is dominant to purple. What would the genotypes be of a suncoast tree that is pure bred purple and tall and a suncoast tree that is heterozygous for both traits?
A. bbTT X BbTt
B. BBtt X BBTT
C. bbtt X bbtt
D. BbTt X BbTt
The genotypes would be bbTT X BbTt
Assuming that bark color is represented by B (b) allele and height is represented by T (t) allele.
Since the traits show simple dominance: blue (B) of dominant over purple (b) and tall (T) is dominant over short (t)

Which situation would increase the fluidity of a
phospholipid bilayer?
A. decreasing the temperature
B. increasing the number of proteins
C. increasing the number of cholesterol molecules
D. increasing the number of unsaturated fatty acids
Answer:
C
Explanation:
Cholesterol molecules stay in between fatty acid tails preventing them from sticking together
The situation that would increase the fluidity of the phospholipid bilayer is increasing the number of cholesterol molecules. The correct option is C.
What is a phospholipid bilayer?A phospholipid bilayer is a layer around a cell. The cell membrane is composed of a bilayer of phospholipids. It contains fatty acids and alcohol.
Bilayers of phospholipids are essential parts of cell membranes. The lipid bilayer serves as a physical barrier to the entry and exit of molecules and ions from the cell. However, allowing the selective transit of specific substances into and out of cells is a crucial role of the cell membrane.
Cholesterol is present between fatty acid molecules and prevents them from sticking to each other.
Therefore, the correct option is C. increasing the number of cholesterol molecules.

Explanation: The excretory system's function is to filter out cellular wastes, toxins and excess water or nutrients from the circulatory system.
Complete this sentence. Excess ____________ from human activities can cause harmful algal blooms (HABs), such as red tide, that produce toxic effects on aquatic species, marine mammals, and birds, as well as on the humans who eat them.
Nitrogen
Carbon
Salt
Heat
Answer: Nitrogen
Explanation:
Harmful algal blooms can occur in lakes, reservoirs, rivers, ponds, bays and coastal waters, and the toxins they produce can be harmful to human health and aquatic life. Harmful algal blooms are mainly the result of a type of algae called cyanobacteria, also known as blue-green algae.
The answer is nitrogen, nitrogen helps algae grow and when it grows in excess it takes away the dissolved oxygen from the water which kills off fish, which puts more nitrogen in the water making algae grow even more until it snowballs and destroys the aforementioned ecosystem.

how many chromosomes would be found in an allopolyploid plant if its parents had diploid numbers of 2 and 10, respectively?
Answer:
6
Explanation:
The allopolyploid off spring should have 6 chromosome the gametes produced for the diploid number 2 should be 1 and for 10 it should be 5 (n/2) the two gametesof both parents gametes should then fuse ( 1+5 ) giving us 6
or
gamete chromosomes =n÷2
gametes for diploid number 2
N= 2
2÷2 = I
gamete Chromosome = 1
gamete for diploid number 10
N=10
10÷2 =5

How does 02 enter the mitochondria
How does oxygen enter the mitochondrial matrix? The electrons taken from NADH and FADH are passed to several other proteins in the inner mitochondrial membrane. Ultimately, they are passed to oxygen (O2). O2 becomes two molecules of water (H2O) after receiving four electrons. This is how oxygen is used by cell respiration.

when a tautomeric shift occurs, what is true about the resulting mutation?
When a tautomeric shift occurs, then the resulting mutation ALWAYS changes a purine to a purine or a pyrimidine to a pyrimidine. A tautomeric shift may lead to a point mutation.
A mutation is any alteration in the nucleotide (DNA) sequence of the genome of an individual.
A tautomeric shift can be defined as a temporary change in the nucleotide base structure.
A transition mutation is a point mutation of one purine or pyrimidine base pair to the other purine/pyrimidine that occurs when one nucleotide base undergoes a tautomeric shift during DNA replication.

B
Both cell types contain a nucleus.
© Both cell types undergo cell division by mitosis.
D
Both cell types contain membrane-bound organelles.
Answer:
C.
Explanation:
Because for answer A, only eukaryotes have DNA, also for B, only eukaryotes have a nucleus and lastly, for D, only eukaryotes contain membrane-bound organelles. hope this helps :)
Both cell types undergo cell division by mitosis. Therefore, option (C) is correct.
What are eukaryotic and prokaryotic cells?A nucleus and other membrane-bound organelles are exclusively found in eukaryotic cells, which is the main distinction between prokaryotic and eukaryotic cells. Prokaryotes and eukaryotes, respectively, are made up of prokaryotic and eukaryotic cells. Eukaryotes often have several cells, but prokaryotes are invariably unicellular. Eukaryotic cells are also between 100 to 10,000 times bigger and more complicated than prokaryotic cells.
Prokaryotic DNA is kept in the cytoplasm, while DNA in eukaryotes is kept in the nucleus. Additionally, double-stranded chromosomes that are compressed by histones are where eukaryotic cells store their DNA. Prokaryotic organisms, on the other hand, only contain one basic circular chromosome and a variety of plasmids, which are tiny DNA rings. In comparison to prokaryotic cells, the DNA of eukaryotic cells contains a higher percentage of non-coding DNA and proportionately less coding DNA.
