Answer:
Four (4) cells
Explanation:
Meiosis is the type of cell division in which four daughter cells that are genetically different is produced. The daughter cells are gametes that have undergone a reduction in their chromosome number (by half).
For example, one cell of an oak tree with 14 chromosomes is said to undergo meiosis. This means that, based on the explanation of meiosis above, the oak cell will give rise to four (4) daughter cells containing 7 chromosomes each.
Which of the following is not true about organic farming?
A) It is more like a natural ecosystem than a monoculture.
B) It occupies a small fraction of U.S. farmland.
C) It minimizes negative environmental impacts.
D) It contributes a large amount to agricultural income.
E) It produces foods that do not contain artificial compounds.
Answer:
B
Explanation:
i took the test
The statement that is not true about organic farming is that occupies a small fraction of U.S. farmland. The correct option is B.
What is organic farming?Organic farmers avoid using synthetic pesticides and fertilizers, which are major contributors to greenhouse gas emissions.
Organic soil organic matter helps crops obtain nitrogen, phosphorus, and other nutrients from healthy soils.
Organic farming is thus important because it is a holistic production management system that promotes and improves agro-ecosystem health, including biodiversity, biological cycles, and soil biological activity.
Many studies have demonstrated that organic farming methods can produce higher yields than conventional farming methods.
Organic farming is an agricultural approach that promotes healthy products free of ingredients that can harm humans and the environment. The statement about organic farming that is not true is that it occupies a small percentage of farmland in the United States.
Thus, the correct option is B.

While looking at a cell under a microscope you notice there is no nucleus and the
chromosomes are double stranded (they have 2 sister chromatids). What phase of mitosis is
the cell probably in?
Answer:
This is the Prophase. Mitotic Prophase,
Explanation:
The process cell division where the cells divides two similar daughter cells(2n) is called mitosis. Therefore it is called a multiplication division because two daughter cells are form from a single the mother cells. Each of the daughter cells can also undergo Futher divisions.
It is the second stage fist mitotic cells division after the first phase called Interphase.
In this stage, the nuclear membrane disappear, nucleolus disintegrate and the nucleus disappeared This is followed by the constriction of the chromosome to sister chromatids.
The constricted nuclear membrane leads to the releases of the chromatids This is followed by the formation of the spindles fibers which are needed for the movement of chromosome for cross over.
other phases are Interphase Prophase Metaphase Anaphase Telephase(IPMAT)
Which statement is TRUE of an archaeological survey?
A. Small test pits can be conducted in an undisturbed part of the surveyed area to find buried artifacts that may not be readily seen on the surface
B. Archaeological sites are always found by accident during survey
C. Archaeological surveys are only conducted during evaluations for cultural resource management (CRM) projects
D. Surface surveys are conducted directly after excavations to assess overall damage(s) to a site
Answer:
The correct option is A.
A. Small test pits can be conducted in an undisturbed part of the surveyed area to find buried artifacts that may not be readily seen on the surface.
Explanation:
This is because archeological survey refers to the study , exploration and digging of sites to obtain archeological remains. The basic sim of this is to get remains that are not visible to man underneath.
usually , the sites are dug out by a shovel so as to determine whether the soil contains any archeological emains that cannot be seen on the surface. This involves the action of excavating the out something or remains especially an archaeological site.

Tropical rain forests receive heavy rainfall. How do the trees and plants of this region withstand rotting?
Answer:
The trees and plant withstand rotting in tropical rain forest using some of these mechanisms.
Explanation:
Tropical rain forests are known for the presence of heavy rainfall, due to this, there might be a lot of water retention in the root. Some trees and plants however are able to store this water and use some of the below mentioned methods to prevent decay and rot.
Some trees in the tropical rain forest may produce very hard outer layer, these hard outer layer will protect the plant and trees form predators and microorganisms from penetrating into the inner tissues of the tree.
Some withstand rotting by producing chemical compounds, these chemical compounds prevents predators and microorganisms from destroying the plants and trees.

The diagram shows a model of a section of double-stranded DNA. The straight lines and dotted lines represent chemical bonds between the
components of the molecule.
During DNA replication, which chemical bonds break apart? Select all that apply.
The DNA has two double strands, and they have different chemical bonds, so during the DNA replication, the hydrogen bonds that are present between the two strands break to separate the DNA.
What role does DNA replication play?DNA replication is the process of making two DNAs from a single DNA, and here the hydrogen bonds that are present between the bases, such as thymine and adenine, which have two hydrogen bonds, and guanine and cytosine, which have three hydrogen bonds, break. The purpose of DNA replication is to make a copy of the genetic content of the cell so that it can be passed to other cells.
Hence, the DNA has two double strands, and they have different chemical bonds, so during the DNA replication, the hydrogen bonds that are present between the two strands break to separate the DNA.

Which MOLECULES are DIRECTLY involved in protein synthesis-translation? (choose 3)
1. mRNA
2. rRNA
3. tRNA
4. cytoplasm
5. sugar
6. DNA
7. Golgi Apparatus
8. amino acid
The translation is directly facilitated by mRNA, tRNA, and rRNA. A specific DNA sequence termed a gene is used as a template during gene transcription to produce a messenger RNA (mRNA), so 1, 2, and 3 are directly involved.
What is the process of protein synthesis?The ribosomes are the next location this mRNA visits before being employed to translate it into a protein.
A ribonucleoprotein complex called the ribosome is made up of proteins and ribosomal RNA (rRNA) sequences.
The linear order of the amino acids that will be added to the protein is indicated by the triplets of nucleotides, or "codons," in the mRNA.
Therefore, the process of translating mRNA into the chain of amino acids that makes up the produced protein occurs in ribosomes in the cytoplasm of the cell.
