Answer:

Sister chromatids / centromeres: When a single chromosome has been replicated in copies, each copy is called a sister chromatids.

A special part of the chromosome called the centromere holds the two sister chromatids together. A centromere is like a built-in rubber band for two sister chromosomes.

Mother cell / daughter cell: identical.

Daughter cells are genetically identical to the mother cell at the stage of production through mitosis.

On the other hand, at the stage of production through meiosis, the daughter cells are genetically different and contain only half of the genetic material of the mother cell.

Interphase / cell division: A cell spends most of its time in what is called interphase, and during this time it grows,

replicates its chromosomes, and prepare for cell division.

The cell then leaves Interphase, undergoes mitosis, and completes its division.

DNA / chromosome: Genes are segments of deoxyirbonucleic acid (DNA) that contain the code for specific protein that functions in one or more types of cell in the body

Chromosomes are structures within cells that contains a person's genes. Genes are contained in chromosomes, which are in the cell nucleus.

Mitosis / cytokinesis: Basically, mitosis is a process by which the duplicated genome in a cell is separated into halves that are identical in nature.

Cytokinesis is the process where the cytoplasm of the cell divides to form two 'daughter' cells. The result is the formation of two 'daughter cells', each having a nucleus.

Answer:

Hypomagnesemia

Explanation:

  • Hypomagnesemia is a condition of low magnesium levels in the body and because magnesium acts as an active cardiovascular electrolyte, its deficiency leads to cardiac complications such as dysrhythmias.
  • People who suffer from myocardial infarction are often treated for hypomagnesemia to improve their cardiac conduction, however, hypomagnesemia can also develop in chronic alcoholics.
  • The other reasons that could lead to the condition faced by Robert Stevens can be hypokalaemia however, as he is also chronic alcoholic hypomagnesemia is the main cause.

You are a farmer who has been noticing that many of your crops are getting destroyed as a result of pests. You hear about a new
quester [9]

Answer:

Explanation:

the advantages include:

disease and drought resistant crops that require fewer environmental resources for them to grow

higher yields harvested as the crops are not attacked by pests resulting in humans receiving more food as well as generating more money from the trading of their crops

increased supply of food at a cheaper life and the crops could have a longer shelf life

crops bound to be healthy as they ae not constantly treated by pesticides that could harm people

reduce the use of pesticides that might be a great move for the betterment of the food supply

they reduce the use of toxins that could harm the environment as well as the animals and people

disadvantages

unexpected or harmful genetic changes that could result in humans health being threatened

the process of genetically modifying the crops is quite expensive

due to the plants becoming pest resistant the pests are bound to have no food hence could die leading to some helpful pests such as beetles or ladybugs that actually benefit the environment going extinct

the production of genetically modified crops results in the disruption of biodiversity as you are favouring one specific organism hence resulting in the disruption of the natural gene flow

the crops are modified hence biotech foods may be a threat to the human health

¿cuales son las diferencias de sangre y linfa?
Soloha48 [4]
La linfa carece de células, está constituida por un líquido incoloro y cargada de lípidos y lípidos que provienen del interior de las células, también contienen solamente glóbulos blancos. La función de la linfa es proteger al organismo de los agentes patogenos y trasladarlos a la sangre a fin de que esta los transporte al exterior del organismo.
La sangre tiene color rojizo, contiene células: leucocitos, hematies, minerales, vitaminas, hormonas, plaquetas, agua, oxígeno y dióxido de carbono. Su función es transportar todos los elementos necesarios a la célula y recoger de esta los residuos resultado de sus funciones de mantenimiento celular
