Explanation:

enzyme + substrate complex =

A substrate is a molecule that an enzyme reacts.

enzymes catalyze chem. reactions with substrates. Substrates transform into 1 or more products. released from " active site," substrate is then able 2 receive another substrate molecule.

Answer:

An enzyme is catalyzing a reaction.

Explanation:

Two substrates bind to the active site of the enzyme. The enzyme catalyzes the reaction (lowers the activation energy needed to complete the reaction), and the result is the final product: two substrates bound together, and an enzyme that can go on to catalyze more reactions.

Use data from the lab to support claims you make, and provide compelling reasoning. Make an effort touse proper writing conventions in your summary (such as good punctuation, spelling, and capitalization)

Answers

Answer:

   Spectroscopy is the study of the interaction between matter and electromagnetic radiation as a function of the wavelength or frequency of the radiation. Simply, spectroscopy is the study of color as generalized from visible light to all bands of the electromagnetic spectrum; historically, spectroscopy originated as the study of the wavelength dependence of the absorption by the gas phase matter of visible light dispersed by a prism.  Matter waves and acoustic waves can also be considered forms of radiative energy, recently gravitational waves have been associated with a spectral signature in the context of the Laser Interferometer Gravitational-Wave Observatory as well. Spectroscopy, primarily in the electromagnetic spectrum, is a fundamental exploratory tool in the fields of physics, chemistry, and astronomy, allowing the composition, physical structure and electronic structure of matter to be investigated at the atomic, molecular and macro scale, and over astronomical distances.    

    The spectrum is determined by measuring changes in the intensity or frequency of this energy.  The types of radiative energy studied include:  Electromagnetic radiation was the first source of energy used for spectroscopic studies.  Techniques that employ electromagnetic radiation are typically classified by the wavelength region of the spectrum and include microwave, terahertz, infrared, near-infrared, ultraviolet-visible, x-ray, and gamma spectroscopy.  Dynamic mechanical analysis can be employed to radiating energy, similar to acoustic waves, to solid materials. The types of spectroscopy also can be distinguished by the nature of the interaction between the energy and the material example:Absorption- when energy from the radiative source is absorbed by the material.  Elastic scattering and reflection spectroscopy determine how incident radiation is reflected or scattered by a material.  Crystallography employs the scattering of high energy radiation, to examine the arrangement of atoms in proteins and solid crystals. Coherent or resonance spectroscopy are techniques where the radiative energy couples two quantum states of the material in a coherent interaction that is sustained by a radiating field.   Spectroscopic studies are designed so that the radiant energy interacts with specific types of matter.  

During one year, the birthrate in a country is 28 births per 1000 people, and the death rate is six deaths per 1000 people. What is the population growth rate?

Answers

Answer: 22

Explanation: 28/1000-6/1000=22/1000

Birth rate is the births per 1000 people which is subtracted by the death rate which is the deaths per 1000 people, this phenomenon is known as Population growth rate. So, 22/1000 is the population growth rate for this.

What is Birth Rate?

Birth rate is the total number of people born per year per 1000 in the population. Birth rate is also known as Natality.

For example, if 65 births occur per year per 1000 individuals, the birth rate is 65. If it is expressed in the percentage, it is 6.5 per 100 or 65%.

Population is divided into many parts like Juveniles (Period before puberty), adults and Post reproductive adults. Birth rate is higher than the death rate as the population is younger, the faster that population grows.

When the birth rate is expressed as per the age group, this is called the standardized birth rate. Birth Rate is determined by the ratio between the number of live births in a population during a year and total mid-year population for the same year multiplied by 1000.

Thus, birth rate is the births per 1000 people which is subtracted by the death rate which is the deaths per 1000 people, this phenomenon is known as Population growth rate. So, 22/1000 is the population growth rate for this.

where do the light-independent reactions take place in cam photosynthesis?

Answers

Answer:

Explanation:  In plants, carbon dioxide (CO2) enters the leaves through stomata, where it diffuses over short distances through intercellular spaces until it reaches the mesophyll cells. Once in the mesophyll cells, CO2 diffuses into the stroma of the chloroplast, the site of light-independent reactions of photosynthesis.

The place from where the light-independent reactions occur in cam photosynthesis would be:

Chloroplast stroma

Photosynthesis

The chloroplast stroma is where CAM photosynthesis takes place. It starts when the plant's stomata open at night, allowing CO2 gas to flow into the cytoplasm of CAM mesophyll cells.

Carbon dioxide is exclusively collected in CAM plants at night, when the stomata open.

Malic acid is turned back to carbon dioxide during the day.

When the sun shines, light reactions produce energy for the Calvin cycle, which allows carbon dioxide to be transformed into sugars.

HELP PLZ!!!

Answers

Evidences that support the theory of evolution;

1. COMPARATIVE ANATOMY;

This is done to compare the anatomy structures of organisms to check the adaptive changes they have undergone through time. The similarities and differences of different body structures of different organisms are checked.

Through, homologous structures where structures are similar in organisms that share the same ancestor. Example, wings of bat and wings of bird.

Through, analogous structures where structures are similar in function in different organisms. Example, fore limbs of man and monkey which are used for grabbing.

2. COMPARATIVE EMBRYOLOGY;

This is done to check embryo development in different organisms throughout time and check the similarities and differences in their development. Example, embryo of man and fish both have gills at embryo stage and in fish they develop but in man they disappear before birth.

3. FOSSILS RECORDS;

The study of fossils shows the evidence of evolution as scientists study the fossils and the development of organisms present, it displays the changes that have occured throughout the years and how other organisms share ancestors and have evolved.

4. MOLECULAR BIOLOGY;

The study of the genes of organisms to check the relationship between organisms and the changes they have undergone through time. Molecular similarities show shared ancestry of organisms. Example, human and chimpanzee share a common ancestor because they both have a gene that encodes insulin hormone.

what route does a red blood cell take to travel from the lung to the kidney

Answers

Answer:

aorta

Explanation:

the red blood cell goes into the kidney trunk and other lower limbs delivering oxygenated blood around the body. They typically last for 120

days before they die.

The blood enters the heart from left atrium. It leaves through the mitral valve into the left ventricle of the heart. The left ventricle then pumps blood through the aortic valve and into the aorta that feeds the rest of the body through a system of blood vessels.

What is function of lungs?

The lungs allow us to breathe and they carry oxygen into body (called  inhalation) and pass carbon dioxide out called exhalation.

Kidney remove toxins and waste, and excess water from the bloodstream, which is carried out of the body in the form of urine. They helped to produce hormones to form red blood cells, and they turn vitamin D into its active form in the body.
