Calculate the mass of an object that has a density of 20 g/mL and a volume of 5 mL.

Answers

Answer:

Explanation:

density= mass/volume

Answer:

100kg

Explanation:

[tex]density= mass/volume[/tex]

using this formula you can re arrange the equation my moving the volume onto the opposite side

giving you this formula : mass= density x volume

in doing so you can calculate the mass of the object by extracting the relevant information of the question

density=20g/ml

volume=5ml

mass = density x volume

=20 x 5

= 100

Which of these would happen to the cell if cellular respiration stopped?

C. Glucose breakdown would nearly stop or cease entirely.

Explanation:

Answer:

I answered this question before. U didn't give use the answer choices but it would be B.

Explanation:

Cellular respiration includes glycolysis that occurs on the cytoplasm of cells and Krebs cycle that occurs in the matrix of the mitochondria. The whole cellular respiration metabolic pathway produces a net of 36 ATPs (glycolsys produces a net of 2 ATPS and Krebs cycle a net of 34 ATPS). They use glucose as a substrate to harness the energy in its chemical bonds to produce the store this energy in ATPs, the energy currency of cells.

Across a non-permeable membrane that separates solutions of different concentrations

Answers

Answer:

it would most likely occur

———————————————————————————————————————

Across a semi-permeable membrane that separates solutions of different concentrations

———————————————————————————————————————

this is because osmosis is the ‘net’ movement of molecules from a ‘region’ of ‘higher concentration’ to a ‘region’ of ‘lower concentration’ ‘down the concentration gradient’.

the answer is
Across a semi-permeable membrane that separates solutions of the same concentration

A tall pea plant (Tt) is crossbred with another tall pea plant (Tt). The following Punnett square shows the separated alleles for two pea plants.

Which of the following shows the correct match of the box numbers and the genotype of the offspring?

Btw graph is below (ScreenShot)

Answers

Answer:

Explanation:

when you use punnett squares, you cross the different genes with themselves. if T is in the first box on both sides, the genome will be TT. if the box lines up to tt, it will be tt. the boxes on the left use the genes' first letter and the boxes on the right use the second letter.

The result of the cross between Tt and Tt would be TT, Tt, Tt, tt.

Monohybrid crossing

This is a kind of crossing involving only one trait.

The genotype Tt will segregate to T and t respectively.

Crossing Tt and Tt:

Tt x Tt

TT Tt Tt tt

Thus, box 1 will contain TT, box 2 will contain Tt, box 3 will contain Tt, and box 4 will contain tt.

I need help right now lol,So the question is :During high tide, ocean waves often become larger. If the amplitude of a wave increases by a factor of 4, by how much does the energy increase?

Answers

Answer:

1.21 times

Explanation:

The energy of a wave is proportional to the square of the amplitude of the wave.

Mathematically:

e & a²

where

E is the energy of the wave

A is its amplitude

In this problem, the amplitude of the wave increases by a factor of 1.1; it means that the new amplitude can be written as

A=1.1A

Therefore, this means that the energy of the wave increases by a factor:

E' & A'²= (1.1A)² =1.1²A² =1.21A² =

1.21E

Therefore, the energy of the wave increases by a factor 1.21.:

Answer : 1.12 times

What is mixture?

When two or more compounds are combined but each ingredient retains its chemical identity, the result is referred to as a mixture. In other words, there is no chemical interaction between the parts of a combination. According to how consistent they are and how well the components' particle sizes match up, mixtures are categorized.
