When the centromeres split in mitosis,what does the sister chromatids’ name change to?
Answer:
During anaphase 2, the chromosomes' centromeres break, and the spindle fibers pull the chromatids apart. The two split portions of the cells are officially known as "sister chromosomes" at this point.

what are the tools used in mulching?
Answer:
A square-point shovel works best for moving mulch materials such as pebbles, wood chips and sawdust. A pitchfork works well for loose straw mulch.
Explanation:
Answer:
A square-point shovel
Explanation:
Mulch is divided into organic and inorganic. In both cases, it prevents the soil from drying out, weed growth and soil erosion.
Mulching is a way of mowing the grass in which the cut grass is not bought from the grass surface, but it is cut into smaller parts and scattered on the lawn, and in that way your lawn is fertilized and maintained in the right way.
The best tool for this is lawnmowers.

What is one event that may occur during Telophase I?
An event that may occur during Telophase I is: the nucleus of each cell may reappear as two independent cells are being formed.
Meiosis can be defined as a type of cell division or duplication that occurs in all body cells found in living organisms, through which a single cell divides twice to produce four (4) haploid cells (gamete).
Basically, deoxyribonucleic acid (DNA) must replicate before meiosis can occur in all body cells found in living organisms.
Generally, the phases or steps that occur during meiosis include:
Prophase I.Metaphase I.Anaphase I.Telophase I.Prophase II.Metaphase II.Anaphase II.Telophase II.Sometimes, the nucleus of a single cell may reappear when two (2) independent cells are being formed during Telophase I.

Answer:
Biodiversity is the variety and variability of life on Earth. Biodiversity is typically a measure of variation at the genetic, species, and ecosystem level. Terrestrial biodiversity is usually greater near the equator, which is the result of the warm climate and high primary productivity.
What are paired chromosomes called?
Answer:
Humans have 23 pairs of chromosomes--22 pairs of numbered chromosomes, called autosomes, and one pair of sex chromosomes, X and Y. Each parent contributes one chromosome to each pair so that offspring get half of their chromosomes from their
Snapdragons, a flowering plant popular with gardeners, can have red, white, and pink colored petals. When snapdragons with red petals (RR) are crossed with snapdragons having white (WW) petals, the offspring have pink petals. The pink coloration (RW) is a phenotype in between the red and white parental phenotypes. What is this kind of inheritance pattern called?
Answer: Incomplete Dominance.
Explanation: When snapdragons with red petals (RR) are crossed with snapdragons having white (WW) petals, the offspring will have pink petals. This will make the pink coloration (RW). Since both of these genotypes are dominant it is Incomplete Dominance because the R does not completely mask the effects of a recessive allele, which in this case theres none.
Where would you find the hydrophilic amino acid sequences if a protein molecule is placed in water? Explain why. (Hint: EXPLAIN in your own words.)
Answer:
The correct answer is - on the surface.
Explanation:
Proteins are made up of long chains called polypeptide chains made up of amino acid residues linked together. These amino acid residues could be hydrophobic or hydrophilic in nature. Hydrophilic is the nature of water-loving whereas hydrophobic is that tries to avoid water.
So, if a protein placed inside the water the hydrophilic amino acids will be present on the surface of the protein, and hydrophobic amino acids present inside of the protein structure.
Scientists have discovered that there are reproductive isolating mechanisms that can stop a population from interbreeding and possibly lead to the formation of a new species. What is this process called
Answer:
Polyploidy
Explanation:
The isolating mechanism that is capable of stopping a population from interbreeding, possibly leading to speciation is polyploidy.
Polyploidy is a condition in which a species of an organism will have multiple, instead of a diploid, chromosomal set as a result of an error during meiosis.
Non-disjunction during meiosis can make a gamete have a diploid number of chromosomes in the place of a haploid chromosome. A 2n gamete fusing with an n gamete will result in a triploid organism, 2n plus 2n gametes will result in a tetraploid organism, etc.
If the extra chromosomal set is from the same species, such polyploidy is termed autopolyploidy, otherwise, it is termed allopolyploidy. Having extra sets of chromosomes has the capacity to make an organism to be reproductively incompatible with normal diploid organisms of the same species. However, polyploid organisms can either self-pollinate or cross with another polyploid organism, a process that can lead to sympatric speciation.

The appearance of the moon changes in a predictable pattern that lasts approximately 28 days.the changes in appearance are called phases of the moon.what is the main cause of the moon phase
Answer:
The main cause of the moon phases is the changing position of the moon in relation to the sun and the earth.
Explanation:
The moon phases are the perception of the part of the moon that is visible, when observed from the earth. When it is completely visible it is called full moon, when it cannot be seen it is called new moon and the phases between one and the other are called crescent and waning quarters.
The moon can be visible when it receives illumination from the sun but, due to its changes in position with respect to the earth, this illumination can be complete, partial or absent, which defines each of the phases.
When the moon completes its four phases it is called the lunar cycle, and it has an estimated duration of 29.5 days.

Hair color and eye color are examples of discontinuous variation. The correct option is A).
What is the variation?
Variation is the difference or change in the characters or any individual. The variation in the organisms is due to genetic makeup, the genetic makeup of every individual is unique.
Discontinuous variation is where there is a limited number of variations will occur. Eye color and hair color are one of them.
Thus, option (A) discontinuous is correct regarding variation.

Write a short paragraph that explains the relationship between the terms "chromosome," "gene," "DNA," and "allele."
Answer: Genes appear throughout the length of each chromosome, and each chromosome pair has a unique set of genes. ... In a diploid organism, the two corresponding genes in a chromosome pair, or alleles, might be identical or might have different base sequences. Each parent contributes one allele in each pair.Alleles are different forms of same gene. Genes are linearly arranged on chromosomes. Chromosomes contain genetic material of cell i.e. DNA. So chemically alleles, genes, chromosomes are all DNA !

Animal cell organelles
Answer:
Nucleolus: Synthesis of ribosomal RNA.
Nucleus: Contains genes (chromatin).
Ribosomes: Protein synthesis.
Vesicle: Transport of materials within the cytoplasm.
Rough endoplasmic reticulum (RER): Protein synthesis.
Golgi Apparatus: Processes, packages and distributes proteins to other organelles for export.
Cytoskeleton: Structural support of cells; facilitates the movement of the organelles.
Smooth endoplasmic reticulum (SER): Lipid synthesis; drug metabolism.
Mitochondria: Produces energy for the cell called ATP.
Vacuole: Protection of the cell, collect waste products and maintain internal pH, among others. (*) Only in some animal cells.
Lysosome: Cellular digestion.
Centrosome: regulate the cell-cycle progression.
Cell membrane: separates the cell from its environment; regulates the movement of materials in and out of the cell.
Answer:
Animal Cell organelles are cell membrane, cytoplasm, lysosomes, ribosomes, a nucleus, mitochondria, the Golgi apparatus or Golgi bodies, ectoplasmic reticulum, and vacuoles.
Explanation:
You might not count the cell membrane and cytoplasm as organelles because they hold the cell together. the cytoplasm is the fluid in which the other organelles float in, and the membrane is like a fleshy crust for the cell.
Plant cells have two more organelles/structures than animal cells. They are the chloroplast and cellwall. Plant cells also have a central vacuole and maybe some few smaller ones, in contrast to animal cells with many smaller vacuoles. Vacuoles are where things the cell needs (like water) are stored.
