What is the endosymbiotic hypothesis?

Biology
1 answer:
stepan [7]3 years ago
3 0

Answer: What does the endosymbiont hypothesis propose? It proposes that early eukaryotic cells acquired the precursors of mitochondria and chloroplasts by engulfing certain types of bacteria. ... Mitochondria, chloroplasts, and centrioles in eukaryotic cells each contain their own minute and unique supply of DNA.

Explanation:

The first piece of evidence that needed to be found to support the endosymbiotic hypothesis was whether or not mitochondria and chloroplasts have their own DNA and if this DNA is similar to bacterial DNA. This was later proven to be true for DNA, RNA, ribosomes, chlorophyll (for chloroplasts), and protein synthesis.

If a population is steady at its carrying capacity, but then a group of organisms from that species moves in to the same space o
baherus [9]

Answer:

It will remain relatively stable

Explanation:

<u>The carrying capacity (k) of an environment is a factor that represents the maximum number of organisms of a particular species such environment can support based on the resources it has. </u>

<em>Below the carrying capacity</em>, the population of a species still has the potential to increase due to resource availability, and <em>above the carrying capacity</em>, the population has the potential to reduce due to the overstretching of the available resources. Factors that keep the population from expanding significantly beyond the carrying capacity include competition for resources, natural disasters, disease outbreaks, etc.

<em>Hence, if a population is steady at its carrying capacity and a group of organisms from that species moves into the same space occupied by the original population, the carrying capacity will only increase temporarily before factors such as competition and natural disasters operate to bring the carrying capacity to the normal level. </em>

A nurse is preparing a client for discharge following an abdominal hysterectomy for fibroids. After providing discharge teaching
lesantik [10]

Answer:

Answer is option B -  "I should shower rather than take a tub bath."

Explanation:

Abdominal hysterectomy is the surgical removal of a part or all of the uterus by making an incision in the lower abdomen. After the surgery, the patient normally spends 2 - 5 days in the hospital and takes at least 4 - 6 weeks to get completely better. Some of the major discharge instructions are;

  • Drink enough water and eat smaller meals that are rich in proteins and fiber and plenty of fruits and vegetables daily. This helps with the healing process and prevents constipation.
  • Avoid swimming or taking a tub bath, but can take showers.
  • Dressings over the incision should be removed daily and keep the wound area clean.
  • Avoid inserting anything such as tampons into the vagina for 6 weeks after the surgery.
  • Avoid all heavy activity including strenuous household activities, weightlifting, and other strenuous exercises. Short walking and light household chores can be done.
  • Avoid driving if the patient is taking narcotic pain-relieving medicines. Long trips in vehicles or airplanes are not recommended for 4 weeks after the surgery.
