Biology
1 answer:
lesya [120]4 years ago
4 0

Answer:

Time

Explanation:

During photosynthesis availability of sunlight, nutrients and water are essential. Water is split into hydrogen ion and oxygen atoms. The sunlight provides energy that is used to split water molecules. However, time is an independent factor in primary productivity.

What best describes the order of actions by the RNA polymerase ?
geniusboy [140]

Answer Choice “A.” is the most sequentially correct answer choice from my understanding. Binding must occur before the making of mRNA, so Answer Choices C and D can be eliminated immediately. If the RNA Polymerase would detach from the DNA before, then how would it make mRNA? That’s when we are left with Answer Choice A, which seems like the best Answer Choice.

Genes A, B, and C are linked on a chromosome and found in the order A-B-C. Genes A and B recombine with a frequency of 8%, and g
Genrish500 [490]

Answer:

<h2>11.02</h2>

Explanation:

Predict the frequency of a+b+c progeny = 11.02

Step by step Explanation  for all genes

a---8%----b---------24%--------c

Double cross overs = (RF at first locus × RF at second locus)/100

= 8 × 24 /100 =1.92

Double cross over progeny;

a b+ c =0.96

a+ b c+= 0.96

single cross over progeny;

RF = 8

SCO at first locus progeny= 8 -DCO progeny= 8- 1.92 = 6.08

a b+ c+= 3.04

a+ b c= 3.04

single cross over at second locus progeny---

RF = 24

SCO at second locus progeny= 24-DCO progeny= 24 - 1.92 = 22.02

abc+= 11.02;

a+b+c = 11.02;

Total recombinants = 1.92 + 6.08 + 22.02  = 30.02

Total nonrecombinants are = 100 - 30.02 = 69.98

abc = 34.99

a+b+c+ = 34.99.

Instructions: As you respond to Part A and Part B, follow the directions below.
svet-max [94.6K]

A.

The mitochondria is the site of the aerobic respiration in the eukaryotic organism. The mitochondria uses the glucose and the oxygen molecules to form the carbon dioxide, water and ATP (adenosine triphosphate) molecule.

The equation for the aerobic respiration is given below:

C_{6}H_{12}O_{6}+6O_{2}\rightarrow 6CO_{2} + 6H_{2}O

Glucose + oxygen\rightarrowcarbon dioxide + water

All the reaction takes place in the mitochondria, Hence, the givenb lanks can be filled as follows:

1. glucose

2. oxygen

3. carbon dioxide

4. water

5. ATP

B.

The process shown in the figure is aerobic respiration. In the given figure, the mitochondria is shown, the mitochondria is the site of aerobic respiration. The mitochondria obtain the glucose and the oxygen molecule present in the cytoplasm of the cell. The complete aerobic respiration takes place in three steps glycolysis, Kreb cycle and electron transport. In the glycolysis, the glucose is converted into pyruvate. In the Krebs cycle, the pyruvate is oxidised in acetyl-CoA, which undergoes a sequence of reaction giving out ATP from ADP. In the electron transport chain, the NADH as well as succinate, which is formed in the citric acid cycle or Krebs cycle are oxidized, which provides the energy to power ATP synthase (the enzyme involved in the creation of storage of ATP).

What do the results of the agar blocks indicate about the relationship between cell size and diffusion rate?
Irina-Kira [14]

Answer:

s the cube size increases, the surface-area-to-volume ratio decreases (click to enlarge the table below). The vinegar can only enter the cube through its surface, so as that ratio decreases, the time it takes for diffusion to occur throughout the whole volume increases significantly.

There are two basic ways that substances can cross the plasma membrane: passive transport, which requires no energy; and active transport, which requires energy. Passive transport is explained in this section and Active transport is explained in the next section, Active Transport and Homeostasis.
