How does the life cycle of a praying mantis differ from the life cycle of a beetle?

Biology

snow_lady [41]3 years ago
3 0
A praying mantis life cycle does not include the pupa stage. The adult female praying mantis lays 100 to 400 eggs after fertilization. The eggs are laid safely on a firm leaf or stem with a liquid that hardens to be a protective sac structure known as ootheca. The ootheca is a protective casing (very hard and able to survive extreme weather changes) in which the eggs will stay throughout the winter. In mid-spring when the temperatures are warm, the nymphs will hatch when the egg cases crack.

How many amino acids must be obtained in the diet because they cannot be made by the body?
Ivan

Answer:

10

Explanation:

Your body can't produce the ten necessary amino acids and must acquire them from your diet.

The body does not manufacture essential amino acids and must be supplied by food. They don't need to take one meal at a time. The equilibrium is more significant during the day.

The body produces nonessential amino acids from essential amino acids or from the natural degradation of proteins.

Which of the following statements is true for a cell placed in beaker containing an isotonic solution?
Elanso [62]
<span>The answer is C)Water molecules flow in both directions at the same rate. In a hypotonic solution, the water concentration of the cell's cytoplasm is lower than that of the hypotonic solution. In a hypertonic solution, the water concentration of the cell's cytoplasm is higher than that of the hypotonic solution. In, an isotonic solution, there is a balance in the water concentration between the cell's cytoplasm and the solution. Thus, water molecules flow in both directions at the same rate.</span>

The largest chromosome in a particular eukaryote contains 5 x 108 bp. The rate of DNA synthesis is 2500 bp/min at each replicati
yawa3891 [41]

Answer:

a) 200000 minutes

b) 20000 number of replicons

Explanation:

Given,

Total number of base pairs in a particular eukaryote  = 5* 10^8

Rate of DNA synthesis = 2500 bp/min

a) Time taken to replicate the entire chromosome from a single origin of replication located exactly in the middle of the chromosome is equal to total number of base pairs divided by rate of DNA synthesis

= \frac{5* 10^8}{2500}\\= 200000 minutes\\

b) Time taken by an actively growing cell to replicate the entire chromosome=10 minutes

The minimum number of replicons present in this chromosome is equal to total time taken for replication divided by time taken by each replicon

= \frac{200000}{10} \\= 20000

Elden [556K]
<span>The answer to this question would be: Ask the client to cough forcefully and take deep breaths.

The arterial blood gas result shown that the patient blood pH is a bit acidic. The pressure of carbon dioxide is a bit elevated that show the problem is in the respiratory organ. The patient that getting surgical is intubated and sedated so there might be fluid build up in the lungs but the cough reflex is decreased. Coughing can help clear the lungs.
