How does a tree use Cellular Respiration to store carbon?
Bogdan [553]

Answer:

In-spiration Respiration in trees releases energy stored in carbon compounds through a controlled process. Aerobic respiration uses O2 to oxidize organic compounds into CO2 and H2O. Energy released is stored within living cells as ATP, ETM, and a proton bank which are easily used for cell work.

Explanation:

You can put it into ur own words.

Several biology students are counting kernels in an ear of corn. They count a total of 420 kernels: 242 purple wrinkled, 84 purp
s2008m [1.1K]
The answer is C) 9:3:3:1

This looks like a dihybrid cross where the expected phenotypic ratio is 9:3:3:1. However, in nature, the numbers cannot be absolut. Let's check it out:
242 purple wrinkled
84 purple smooth
70 yellow wrinkled
24 yellow smooth

Divide all by the smallest number:
242 purple wrinkled / 24
84 purple smooth / 24
70 yellow wrinkled / 24
24 yellow smooth / 24

We have 
10.1 purple wrinkled which is near to 9
3.5 purple smooth which is near to 3
2.9 yellow wrinkled which is near to 3
1 yellow smooth

Which hormone causes FSH and LH to be released?
vodomira [7]

Answer:

GnRH

Explanation:

GnRH stimulates pituitary secretion of luteinizing hormone (LH) and follicle stimulating hormone (FSH). LH and FSH then stimulate the ovaries, resulting in the growth of secondary preantral follicles and ovulation.

Although some release hormones are also secreted in pulses, GnRH is unique because pulsed gonadotroph stimulation is necessary for normal LH and FSH synthesis and secretion, while continuous infusion of GnRH - or the use of such an agonist hormone that stimulates continuous infusion - results in negative modulation of gonadotropic responsiveness to GnRH. This property is clinically used to treat hormone-responsive conditions such as endometriosis and precocious puberty.

A student inoculates a gelatin tube and places it at 37C for the week. When he comes back he takes the tube out of the incubator
ycow [4]
<h2>Gelatin </h2>

Explanation:

Gelatin is a differential medium which tests the ability of an organism to produce an exoenzyme, called gelatinase (this enzyme hydrolyzes gelatin)

When gelatin is at a temperature below 32°C (or within a few degrees thereof), it is a semisolid material and at temperatures above 32°C, it is a viscous liquid

When gelatin is broken down, it can no longer solidify and if an organism can break down gelatin, the areas where the organism has grown will remain liquid even if the gelatin is refrigerated

No the conclusion by student is not right because the tube must be runny after incubation followed by refrigeration to be considered gelatinase positive
