|
Answer» tion:Brassicaceae or Cruciferae is a medium-sized and economically important family of flowering plants, COMMONLY known as mustards, the crucifers or the cabbage family. In Brassicaceae, the flowers are actinomorphic (radial symmetry), bisexual (possess both male and FEMALE flowers), sepals 4 and they are dimerous (arranged in two whorls), petals 4 and they are arranged in a single whorl, stamens 6 and they are tetradynamous (two lateral stamens are smaller and four MEDIAN stamens are larger), carpels are 2 (bicarpellary) syncarpous, ovary superior.So, the CORRECT answer is 'A'. |

|
Answer» actic fermentation is a minor process which occurs after glycolysis in anaerobic respiration. In it, an enzyme found in most every organism called lactate dehydrogenase CATALYZES a reaction between the NADH produced from glycolysis with the pyruvate MOLECULES to CREATE the NAD+ necessary to begin glycolysis.2) Anaerobic respiration happens in muscles during hard exercise. Glucose is not completely broken down, so less energy is released than during aerobic respiration. There is a build-up of lactic acid in the muscles during vigorous exercise. The lactic acid needs to be oxidised to carbon dioxide and water later.3) If the food is broken down with the use of oxygen, it is called aerobic respiration. If the breakdown occurs WITHOUT the use of oxygen, the respiration is called anaerobic respiration.1.H2O and CO22. The yeast simply switches from aerobic respiration (requiring oxygen) to anaerobic respiration (not requiring oxygen) and converts its food without oxygen in a process known as fermentation.3.There are five main modes of seed dispersal: GRAVITY, wind, ballistic, water, and by animals. Some plants are serotinous and only disperse their seeds in response to an environmental stimulus. Dispersal involves the letting go or detachment of a diaspore from the main parent plant. |

Define oscillation, time period and amplitude of a simple pendulm |
|
Answer» Oscillation is the repetitive variation, typically in time, of some measure about a central value (often a point of equilibrium) or between two or more different states. The term vibration is precisely used to describe mechanical oscillation.T is the time it takes for one complete oscillation , it is measured in seconds. All WAVES, including SOUND waves and electromagnetic waves , follow this equation. For example, a wave with a time period of 2 seconds has a FREQUENCY of 1 ÷ 2 = 0.5 Hz. A sound wave has a time period of 0.0001 seconds.The amplitude of simple PENDULUM: It is defined as the distance travelled by the pendulum from the equilibrium position to one side. Length of a simple pendulum: It is defined as the distance between the point of suspension to the centre of the bob and is denoted by “l”.Explanation:hope it helps! |

Why do we use mercury as thermometric liquid? |
| Answer» MERCURY is the only one in liquid state at room temperature. It's used in THERMOMETERS because it has high coefficient of expansion. Hence, the slightest change in temperature is notable when it's used in a thermometer. It also has a high boiling POINT which makes it very SUITABLE to MEASURE higher temperatures. | |

Complete the correlation:- Calcitonin : calcium metabolism : : Antidiuretic hormone : ---------- * Regulation Of water and sodium levelGive rise to immunityMilk productionGrowth of body |
|
Answer» othalamus monitors the amount of water in the body by sensing the concentration of electrolytes in the blood; a high concentration of electrolytes means that the level of water in the body is low.Antidiuretic hormone (ADH), produced by the hypothalamus and RELEASED by the posterior pituitary, causes more water to be RETAINED by the kidneys when water levels in the body are low.ADH EFFECTS water retention by creating special channels for water, called aquaporins, inside the kidneys so that more water can be reabsorbed before it is excreted.Aldosterone, produced by the adrenal cortex, causes the retention of water in the body by INCREASING the levels of sodium and potassium ions in the blood, which causes the body to REABSORB more water.When blood pressure is low, the enzyme renin is released, which cleaves the protein angiotensinogen into angiotensin I, which is further converted into angiotensin II.Angiotensin II signals the adrenal cortex to release aldosterone, which then increases the retention of sodium ions, enhancing the secretion of postassium ions, resulting in water retention and an increase in blood pressure. |

Why?2) Should girls cook during menstrual days or not? Why? |
|
Answer» tion:1= It can be move with a smaller FORCE because it has crossed the static friction now it have only the kinetic friction which is low and second way we can say that the body is started moving so no static force is required. 2,=Because aeroplane need streamlined body to fly in the sky.3= SHOE with nail to play on the field because you can get a PERFECT grip on the ground which the flat bottom shoe can't provide. 4= yes, girl should cook in their menstrual days these are just some rumours that some people believe on. |
