1. How does amoeba feed ? (3 points)
there is two question
Answer:
Hey mate here's your answer ⤵️
1. Amoebae typically ingest their food by phagocytosis, extending pseudopods to encircle and engulf live prey or particles of scavenged material. Amoeboid cells do not have a mouth or cytostome, and there is no fixed place on the cell at which phagocytosis normally occurs.
2. Unicellular organisms are made up of only one cell that carries out all of the functions needed by the organism, while multicellular organisms use many different cells to function. ... Multicellular organisms are composed of more than one cell, with groups of cells differentiating to take on specialized functions.

Explain why both arguments are valid in the scenario below.
Situation: Students Claire and Don are debating the future security of food production. Claire feels that it is most
important that food producers focus on producing enough food to keep up with the world's ever-growing population by
using innovations like biotechnology. Don feels that food producers should focus primarily on adopting methods that
are environmentally friendly and safe for human and animal health.
Answer:
Both the arguments are valid.
Explanation:
Claire thinks enough food should should be produced for everyone, because the world's population is rapidly increasing. Don thinks the environment should be kept in mind, because our environment is getting ruined every second. Hence, both arguments are valid.

State four ways by which animals living in arid and semi arid areas conserve water
Answer:
Arid or Semi-arid regions are defined as the regions that receive little precipitation.
Four ways by which animals living in arid and semi-arid areas conserve water are as following:
They live in burrows to avoid water leaving their body.Some animals have a thick outer covering which reduces moisture loss, such as Scorpions and wolf spiders.Kidneys of animals in arid or semi-arid regions concentrate urine that helps in less excretion of water.Some animals like Gila monsters and camel have the ability to store water in their body such as in their tails and hump respectively, that can be reabsorbed when needed.can sum1 help me wit dis
Dioptría de una persona que puede enfocar hasta 30 cm sin gafas
Answer:
3.33
Explanation:
El término ditropía hace referencia al potencial de refracción de una lente. Por ejemplo, un valor de ditropía de un (1) metro de una lente convergente indica que los rayos que atraviesan dicha lente convergen a un (1) metro de distancia detrás de la lente. De este modo, el valor de dioptría es inverso de la distancia focal expresada en metros. Para calcular el nivel de ditropía se utiliza la siguiente fórmula:
C = 1 / d
donde C equivale al poder de refracción (en unidad de dioptrías) y d equivale a la distancia focal o último punto de enfoque (en metros)
En este caso:
30 centímetros = 0.3 metros >>
C = 1/0.3 m
C = 3.33 dioptrías
If you are ever stuck in a lightning storm while in your car, you should remain in your car. This is because the rubber tires do not allow for the heat and electricity of the lightning to pass through the vehicle. What physical property is this?
malleability
conductivity
density
viscosity
Answer:
Conductivity
Explanation:
Conductivity is the property of a material which describes the ease with which that substance permits or conducts heat and electricity through it.
Materials can either be good, poor or non-conductors.
Good conductors are those materials which allow heat and electricity to pass through them easily. Such materials are useful in making electrical wires and heating vessels. Metals are good conductors of heat and electricity.
Some other materials are poor conductors of heat and electricity as they do not allow heat or electricity to pass through them easily. Examples are air and water.
Some other materials are non-conductors as they do not allow heat and electricity to pass through them. These materials are otherwise known as insulators. They are useful in making things such as pot handles, electrical wire insulators, etc. Examples of insulators are plastic, rubber, wood, etc.
Someone in a car during a thunderstorm is safer inside because the rubber tires do not allow for the heat and electricity of the lightning to pass through the vehicle as it is a non-conductor of heat and electricity.
