In a completely dark room, you can’t see your reflection in a mirror. Give reason.
[tex]\huge{\underline{\bigstar{\mathfrak{Answer:-}}}}[/tex]
An image is formed due to reflection of light by a plane mirror. In a completely dark room there is no light so no image will be formed by the mirror placed in the room. Hence we will not be able to see our image in a mirror placed in a completely dark room.

The stage of spinal shock that follows spinal cord injury is characterized by a. absent spinal reflexes below the level of injury. b. autonomic dysreflexia. c. motor spasticity and hyperreflexia below the level of injury. d. reflex urination and defecation.
Answer:
The correct answer is a. absent spinal reflexes below the level of injury.
Explanation:
Spinal shock strictly refers to the neurological condition that occurs immediately after a spinal cord injury, in which the loss of not only motor and sensory functions occurs, but also the abolition of all reflexes below the injury (reflexes of muscular or myotatic stretching and cutaneous reflexes). There is also flaccidity, loss of reflexes. It is characterized by hypotension associated with cervical or upper thoracic spinal injuries. This characteristic shock results from the lesion of the descending sympathetic pathway in the spinal cord, producing a loss of vasomotor tone and sympathetic innervation of the heart. This causes vasodilation of the affected area with accumulation of blood and a decrease in venous return to the heart as well as cardiac output.

Explain the Water Cycle
Answer:
PRECIPITATION
SURFACE RUNOFF
GROUNDWATER
EVAPORATION AND TRANPIRITATION FROM TREES
REPEAT
Explanation:
Answer/Explanation:
The water cycle shows the continuous movement of water within the Earth and atmosphere. Liquid water evaporates into water vapor, condenses to form clouds, and precipitates back to earth in the form of rain and snow. Water in different phases moves through the atmosphere (transportation).
There are four main stages in the water cycle. They are evaporation, condensation, precipitation and collection. Let's look at each of these stages. Evaporation: This is when warmth from the sun causes water from oceans, lakes, streams, ice and soils to rise into the air and turn into water vapour (gas).
Hence it is quite important to understand and learn the processes of the water cycle.
Step 1: Evaporation. The water cycle starts with evaporation. ...
Step 2: Condensation. ...
Step 3: Sublimation. ...
Step 4: Precipitation. ...
Step 5: Transpiration. ...
Step 6: Runoff. ...
Step 7: Infiltration.
It is also known as the hydrological cycle or the hydrologic cycle. During the process of the water cycle between the earth and the atmosphere, water changes into three states of matter – solid, liquid and gas. The diagram of the water cycle is useful for both Class 9 and 10.
Write a concise essay on animal-like Protista and pay attention to their classification and their effects on human and their domestic animals and suggest some methods
Answer:
Animal-like Protists belongs to Kingdom Protista.
Explanation:
Animal-like Protists are those unicellular organisms which have animal characteristics like movement and heterotroph. They are not classified in the kingdom Animalia due to some characteristics such as made up of one cell. Animal-like Protists has a great effect on human and their domestic animals because they cause disease in them. Some animal-like Protists are also act as a decomposer means feed on dead bodies of human and animals and clean our environment so animal-like Protists cause an important effect on both human and animals.

What is the process of Sexual reproduction of a Hammerhead Shark?
Answer:
The process of sexual reproduction of a hammerhead shark is that the hammerhead sharks exhibit a viviparous mode of reproduction with females giving birth to live young.
Explanation:
Answer:
The hammerhead sharks exhibit a viviparous mode of reproduction with females giving birth to live young. Like other sharks, fertilization is internal, with the male transferring sperm to the female through one of two intromittent organs called claspers. The developing embryos are at first sustained by a yolk sac.

Plan a controlled experiment that uses the simulation to investigate how changing the mass of an object changes its acceleration. The net force on the object must stay the same. Record your plan here.
It is possible to measure how acceleration changes with mass by throwing objects with different mass from the same height and measuring the acceleration.
What are the important factors for the experiment?This experiment requires you to measure how acceleration changes if the mass changes. This implies you need to consider the following factors:
Acceleration: This factor is the one you will measure in your experiment.
Mass: This factor is the one you will need to control, this implies using objects from different masses and comparing if mas has any effect on acceleration.
Other: Net force, wind, etc. are other factors that need to be constant to prevent them affect the results.
Steps for the experiment:
Choose a specific heigh: One of the ways of measuring acceleration is to throw objects and determine the acceleration as they fall, so the first step will be to establish a height.
Throw different objects with different masses: You can begin with light objects and move into heavier objects.
Measure acceleration: Every time you throw an object, measure acceleration using the formula A = change in velocity/ time.

A species of elm has winged-seeds. How would biologists explain how a species of elm with winged-seeds evolved from an ancestral elm species without winged-seeds
Answer:
In an ancestral elm species, mutations gave rise to the phenotypic trait "winged-seeds". Subsequently, selection favored elm plants with winged-seeds that diverged over time to become a separate species
Explanation:
A mutation is a genetic change in the DNA sequence. In general, mutations have a negative impact on the fitness of the individual (i.e., mutations are generally deleterious) and therefore they disappear from the population. However, there are situations where mutations are beneficial and confer an adaptive advantage, thereby increasing their frequency in the population. In this case, mutations associated with the formation of winged-seeds conferred an adaptive advantage (i.e., higher seed dispersal capacity) to individuals who had this phenotypic trait, thereby these individuals had more chances to reproduce and pass their genes to the next generation. Eventually, Elm plants with winged-seeds accumulated sufficient genetic differences to prevent interbreeding, leading to the formation of a separate species.

Which of the following accurately describes plasma?
a. It includes all the blood except the red blood cells.
b. It makes up 30% of whole blood.
c. It is the liquid portion of blood that includes the clotting factors.
d. It is the liquid portion of blood including the formed elements.
e. It contains the blood antigens that determine blood type.
Answer:
The correct answer is - option C.
Explanation:
Plasma is the liquid portion of the blood that carries water, salts, and enzymes in it and comprise almost 55% of the total blood volume. Other 45% of blood contains RBC, WBC, and platelets.
It is a yellow liquid that contains a clotting factor that helps in clotting blood if any injury occurs. Antigens are present on the RBCs not in the blood plasma that determines blood type.

Anaerobic bacterial fermentation occurs in the absence of:
Bacteria
Enzymes
Oxygen
All of the above
Answer:
Oxygen
Explanation:
Cellular respiration is a pivotal process that must be carried out by the cells of living organisms in order to obtain energy needed for their metabolic activities. This process of cellular respiration breaks down glucose either in the presence of OXYGEN (aerobic) or absence of OXYGEN (anaerobic).
Anaerobic respiration or fermentation is carried out by certain bacteria in the absence of OXYGEN to produce lactic acid as products.
