Answer:
Approximately it will consume 55% of the total time in the interphase i.e. 800 minutes.
Explanation:
The time required in different phases are as follows:
It takes 800 minutes for interphase
It takes 400 minutes for prophase
It takes 120 minutes for metaphase
It takes 80 minutes for anaphase
It takes 40 minutes for telophase
Total -- 24 hours
From this it can be concluded that around 55% of the time spent in the interphase, whereas only 28% in the prophase, 8% time for metaphase, 6% Anaphase and 3% Telophase. This is all happens in the onion cell but in case of the human cell, prophase it takes about 15 min, in prometaphase it takes 15 mins, metaphase takes in about 20 min, Anaphase takes minimum of 3 min and telophase is about and cytokineses are about less then 10 mins.
Answer:
b) 1,000
Explanation:
In a typical food chain as described in this question, flow of energy occurs from one organism to another when they feed/fed upon. As one organism feeds, energy gets transferred to it. However, only about 10% of the available energy in the lower trophic level gets transferred because majority of the energy (about 90%) is lost as heat during metabolic processes of the organism.
Hence, if a flower contains approximately 100,000 units of energy and is fed on by butterflies. 10% of 100, 000 = 10,000 units gets transferred to the butterflies.
Likewise, the butterflies gets fed on by certain bird species. 10% of the available 10,000 units of energy in the butterfly gets transferred to the birds.
= 10/100 × 10,000 = 1000 units of energy.
Answer:
Change occur in form and structure of the cell.
Explanation:
The structure and shape of the cell change because the function of leg is different from the lungs. In the lungs the epithelial lung cell is responsible for the detection and protection of the cells against pathogen while on the other hand, the leg has the function to move an individual from one place to another so due to difference in function, the cells of both regions have different shape and structure of the cell and the epithelial lung cell will be changed into a leg muscle cell.
Answer:
the kidneys excrete salt into the urine when dietary salt levels rise
Explanation:
Hyponatremia is an electrolyte imbalance, with a low level of sodium in the blood. The normal value of sodium in adults is 136 to 145 mEq / L. Sodium is an element, or electrolyte of the blood. Sodium chloride is commonly known as table salt.
Certain conditions can cause decreased sodium in the blood. Specific causes of hyponatremia include:
Water poisoning (water replacement without electrolyte replacement).
Problems in the kidneys, heart or liver.
Medications: such as diuretics, Heparin, certain chemotherapeutics (Aminoglutethimide, Cyclophosphamide and Vincristine).
Conditions related to steroids, hormones or metabolic defects, such as a syndrome that alters the secretion of antidiuretic hormone (SSIHA). If this occurs, you urinate frequently and the kidneys excrete too much sodium. This can result from many conditions, including certain types of lung cancer.
Answer:
In compare to eukaryotes,prokaryotes are morphologically simpler,more evolutionary primitive,less sensitive to physical environment.
Explanation:
Prokaryotes are unicellular organism which don't possess cell organelle like nucleus,mitochondria,Endoplasmic reticulum,golgi body, etc.
They are the first living organism in the primitive earth and the genetic components are located in the cytoplasm which is enclosed by cell membrane.
prokaryotes contain 3 domains that are Archaea, bacteria and eukarya.
The cytoplasm is enclosed by cell membrane.
Molecular studies have reveal that eukaryotes are evolved from prokaryotes.
Some prokaryotes bear long projection which helps them for locomotion,called as flagellum.This is present in gram positive and gram negative bacteria.
