Answer:

Condensation is a process in which water vapors changed into liquid state.

Explanation:

Condensation is a process in which water that is present in the vapors form changed into liquid state. Condensation greatly affect Earth systems because this process is responsible for the precipitation on the earth. Condensation occurs in the atmosphere when warm air rises in the atmosphere, cools and unable to hold water vapor. As a result, water vapors condenses to form cloud droplets that falls in the form of rainfall.

"In genetic modifications, DNA inserted can come from _____ ." any organism containing the DNA of interest only the same plasmid
liq [111]

Answer:

<h2> any organism containing the DNA of interest</h2>

Explanation:

  • Such type of process in which the modification of the genes of the organisms takes place is known as genetic modification and also called genetic manipulation or genetic engineering.
  • In such type of the process, the branch of biological science that is known as biotechnology is used.
  • In this mechanism, genes of interest are separated from the certain organism and then this gene of interest is inserted into the host organism and such type of DNA that is formed after the addition of foreign genes or DNA is called recombinant DNA.
  • Such type of DNA is used in the production of genetically modified organisms and some other fields for the benefit of human beings.

Compare and contrast Prophase and Telophase. what is different about DNA of the chromosomes in these phases. ( Max 5 Sentences )
shepuryov [24]

Answer:

The C. elegans embryo is a powerful model system for studying the mechanics of metazoan cell division. Its primary advantage is that the architecture of the syncytial gonad makes it possible to use RNAi to generate oocytes whose cytoplasm is reproducibly (typically >95%) depleted of targeted essential gene products via a process that does not depend exclusively on intrinsic protein turnover. The depleted oocytes can then be analyzed as they attempt their first mitotic division following fertilization. Here we outline the characteristics that contribute to the usefulness of the C. elegans embryo for cell division studies. We provide a timeline for the first embryonic mitosis and highlight some of its key features. We also summarize some of the recent discoveries made using this system, particularly in the areas of nuclear envelope assembly/ dissassembly, centrosome dynamics, formation of the mitotic spindle, kinetochore assembly, chromosome segregation, and cytokinesis.

1. The C. elegans embryo as a system to study cell division

The C. elegans embryo is a powerful model system for studying the mechanics of metazoan cell division. Its primary advantage is that the syncytial gonad makes it possible to use RNA interference (RNAi) to generate oocytes whose cytoplasm is reproducibly (>95%) depleted of targeted essential gene products. Introduction of dsRNA rapidly catalyzes the destruction of the corresponding mRNA in many different systems. However, depletion of pre-existing protein is generally a slow process that depends on the half-life of the targeted protein. In contrast, in the C. elegans gonad, the protein present when the dsRNA is introduced is depleted by the continual packaging of maternal cytoplasm into oocytes (Figure 1). Since depletion relies on the rate of embryo production instead of protein half-life, the kinetics tend to be similar for different targets. By 36-48 hours after introduction of the dsRNA, newly formed oocytes are typically >95% depleted of the target protein.

A group of scientists are observing a new found cell. They want to classify it as either a prokaryotic cell or a eukaryotic cell
valkas [14]
  • The question can be solved by using the difference between eukaryotic and prokaryotic cell.
  • Prokaryotic cell does not have a well defined nucleus. The nuclear material lies naked in the cytoplasm. It is known as nucleoid. While, eukaryotic cell has a well defined nucleus with a nuclear membrane.
  • Prokaryotic cell has a single chromosome while eukaryotic cell has more than one chromosome.
  • Finally, prokaryotic cell do not have membrane-bound cell organelles while eukaryotic cell have membrane-bound cell organelles.

Hope you could get an idea from here.

A 53-year-old man presents to the emergency department with a chief complaint of inability to form words, and numbness and weakn
mote1985 [20]

Answer:

Explanation:

This is a stroke and the site of injury is the left side of the brain, this occur when the flow of oxygen-rich blood to a portion of the brain is blocked. Without oxygen, brain cells start to die after a few minutes.

A stroke occurs if their sudden bleeding in the left side of the brain, the right of the body will be affected, producing some of the following: numbness and weakness of the right arm and leg Speech problems (inability to form words). Amongst other symptoms.

The left side of the brain is responsible for controlling the right side of the body.

Stroke may occurs at any age and strock risk increase with age
