Cells can regulate what they need or don't need to maintain their own health. True False

Biology
1 answer:
Yakvenalex [24]3 years ago

True. This is called cellular homeostasis. This happens when cells are able to produce and excrete materials within their environment to regulate processes like cellular respiration, phagocytosis, and pinocytosis. If cells are not able to do this, mutations and excessive cellular division may occur causing abnormalities in specific organisms.

¿Que aspecto debemos considerar para desidir el uso mas adecuado de lagunos materiales en la satisfacción de necesidades humanas
umka21 [38]

Answer:

El efecto del material sobre el medio ambiente es el aspecto a considerar.

Explicación:

Se debe verificar la estructura química del material o de qué elementos se forma un material para conocer el efecto de estos materiales en la salud y el medio ambiente de las personas. Si los materiales no afectan el medio ambiente y la salud humana, el ser humano puede utilizarlos para satisfacer sus necesidades. Si el material se forma a partir de elementos tóxicos o elementos que no se descomponen por microbios, entonces este tipo de materiales son peligrosos tanto para la salud humana como para el medio ambiente porque estos materiales contaminan el medio ambiente y debido a esta contaminación la salud humana se ve gravemente afectada.

Convert 0.0701 kg to milligrams
aliina [53]
To convert 0.0701 kilograms to milligrams, we must first figure out how many milligrams are in 1 kilogram.

1 kg (kilograms) = 1,000,000 mg (milligrams).

Since we have 0.0701 kg, we need to multiply 1,000,000 by 0.0701.
1,000,000 x 0.0701 = 70,100.

There are 70,100 mg in 0.0701 kg.

I hope this helps!

A scientist wants to begin making a DNA fingerprint, but she has only a very small DNA sample. What should her next step be
azamat

For obtaining an adequate amount of DNA samples for DNA fingerprinting, polymerase chain reaction (PCR) can be used.

Polymerase chain reaction (PCR) is a technique that is used to amplify the DNA sample. The steps included in PCR are:-

1. Denaturation of the double-stranded DNA (at around 95°C)

2. Annealing of the primers to each of the single-stranded DNA templates ( at around 65°C)

3. Extension or elongation of the primers by considering every single-stranded DNA as a template. This elongation is carried out by <em>Taq </em>polymerase (at around 72°C).

With each cycle of PCR, the DNA sample is increased by 2ⁿ. Here, 'n' represents the number of PCR cycles.
