Answer:

<u>valid</u>

Explanation:

A measurement is considered <u>valid</u> if it actually measures what it is intended to measure, according to the topic of the study.

Validity can be described as accuracy of something. Validity is measuring something which we are actually supposed to measure, whereas reliability shows how consistent or convenient are the results.  Validity states how much accuracy is present in a statement, concept or measurement. The term 'valid' is known to be derived from a Latin word "validus" which means to be strong.

Atmosphere Unit Test
Brrunno [24]

Carbon moves from the atmosphere to the biosphere and also from the atmosphere to the hydrosphere through a variety of processes.

<h3>Carbon cycle</h3>

Carbon in the form of carbon dioxide in the atmosphere is sequestrated by plants (biosphere) through a process known as photosynthesis.

When plants die, their organic matter decomposes into the soil (lithosphere) while some carbon is released back into the atmosphere via decomposition. Soil carbon also helps plants to grow.

Carbon in the atmosphere also gets sequestrated into water bodies (hydrosphere) by dissolution.

We can use a punnett square to predict the outcome of self-fertilization for the f1 hybrids of a monohybrid cross. In this case,
tiny-mole [99]

We can use a punnett square to predict the outcome of self-fertilization for the f1 hybrids of a monohybrid cross. In this case, the punnett square should be set up as a blank 2x2 square.

Self-fertilization is the joining of male and female gametes and/or nuclei from the same haploid, diploid, or polyploid organism. It is an instance of extreme inbreeding. These are 2X2 squares with four boxes for a monohybrid cross, with each box signifying a fertilization between the parent gametes.

Selfing is widespread, ranging from simple hermaphrodite plants and animals to multicellular organisms (especially invertebrates). Selfing occurs when two individuals (or their cell nuclei) that were produced by a previous mitotic division of the same individual interbreed in unicellular organisms like protozoa.

The Punnett square is a table that lists every conceivable result of a genetic cross between two people of known genotype. The Punnett square is a square that has been partitioned into four quadrants in its most basic form.

Why plants Bend and grow towards a light source
Hitman42 [59]
HEYA !!!!

Under normal light conditions auxins are spread out in the plant. But when sunlight varies, auxin is broken down on the sunnier side of the stem. The higher concentration of auxin on the shady side causes the plant cells on that side to grow more so it bendstoward the light.

Hope it helps you..

Describe how Stella’s view of these cells and their parts changed as she transitioned through the three levels of magnification.
Rudik [331]

Answer:

The paramecium body.

Explanation:

1. The objective lenses on a compound light microscope doess have powers that start of as smallest to highest power, 4x, 10x, and 40x on the maximum power setting. This means that the sample can be magnified either, 40x, 100x or 400x.

At 40x magnification Stella will see organism 5mm.

At 100x magnification Stella will be able to see organism 2mm.

At 400x magnification Stella will be able to see organism more closely, 0.45mm, or 450 microns.

2. Paramecia are shoe shape or molded and almost transparent and shrouded in a defensive pellicle.

Pellicle capacities like skin and shields them from the components. For movement they have cilia.
