A scientist studying Florida panthers makes many observations of a population over the course of several years. What is the scie
Afina-wow [57]

By studying the population over an extended period of time, scientists can discover the change in number of population and its growth.

Florida panther population is listed as endangered, but it is estimated that the number is recovering. The population had grown from about 25 adults in 1995 to roughly 100 in 2010. The updated estimates from the 2017. calculated the number between 120 – 230 panthers which is still not a sustainable population size.

Describe the genetic code and its relationship to polypeptides and proteins
konstantin123 [22]

The genetic code is directly related to polypeptides and proteins in the sense that genes are decoded to synthesize proteins.

What is the genetic code?

Genetic code is the set of rules by which the sequence of bases in DNA are translated into the amino acid sequence of proteins.

The genetic code is unique for living organisms and is used to synthesize the proteins that is responsible for various activities in living organisms.

The genes in the genetic code are first transcribed into mRNA, which is then translated into proteins (polypeptides).

Which processes are involved in the chloroplast of a plant cell?
Ahat [919]

Answer:

Chloroplast absorbs sunlight and it is used to make feed for the plant together with water and carbon dioxide gas. Chloroplasts are used to generate the free energy stored in ATP and NADPH via a photosynthesis process.

Explanation:

The site of photosynthesis action is chloroplast within a plant cell consisting of two chlorophyll molecules (PS1 and PS2), which have been embedded in the thylakoid membranes. The chloroplast consists of two chlorophyll molecules (photosynthetic pigments responsible for the green color of chloroplast). Each chlorophyll molecule absorbs light, caused to depart the chlorophyll molecules. This absorbs two electrons from each phenotype. PS2 electrons pass through the transportation chain for electron carriers, a series of redox reactions that release the energy used to synthesize ATP via Photophosphorylation/Chemiosmose (as the H+ ions diffuse through the stalked particles ATP, which changes the shape and catalysts, the electrochemical gradient diffuses down through the stalky particle ATP synthase).

Then these electrons replace the electrons lost in PS1. PS2 electron is replaced by photolysis electron, which when light strikes chloroplast, splitting the water into oxygen gas, H+ ions, and electron enzymes in the thylakoid space are catalyzed. The PS1 electrons combine to create NADPH with H+ ions and NADP (reduced NADP). These are the light-dependent photosynthetic reactions in chloroplasts. In the light-independent reactions, the NADPH and ATP are created. A pile of thylakoids is known as granum.

The light-independent processes take happen in the stroma. This is the site of carbon fixation; CO2 reacts with RUBP to generate GP (glycerate-3-phosphate) which is catalyzed by the enzyme RUBISCO (the most abundant enzyme in the world) (the most abundant enzyme in the world). The NADPH and ATP from the light-dependent processes convert GP to GALP (glyceraldehyde 3-phosphate). Two out of every 12 GALP molecules produced are used to synthesize glucose that can be employed either in breathing or in cellulose-forming condensation polymerization to add extra strength to the planted cell wall. The other GALP molecules are returned to RUBP.

When amino acids are degraded for energy or glucose production, their amine groups are incorporated by the liver into ____.
masya89 [10]

Answer:

The correct answer is - urea.

Explanation:

In our body, to produce energy or produce glucose our body breaks the amino acids, it gets from proteins mainly. These amino acids are mainly breakdown into amine groups.

The human body has a unique ability to pack ammonia(amine group) by converting it to urea and incorporated and produced by the liver using 2 molecules of ammonia (NH3) and 1 molecule of carbon dioxide (CO2).  This incorporated urea is then secreted from the liver and incorporated into the urine in the kidney for further process.
