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?
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.

is usable to all organisms?
A. By combustion of fossil fuels
B. By the decomposition of dead and decaying matter
C. By production of ATP through cell respiration
D. By the making of glucose through photosynthesis
WILL MARK BRAINLIEST
Answer:
D. By the making of glucose through photosynthesis
Explanation:
Photosynthesis is a chemical reaction that results in glucose. One of the reactants is CO2. So, the plants take in CO2, water, and sunlight. This produces oxygen and glucose. This is part of the carbon cycle and is the way that CO2 becomes usable for consumers.

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

“summarize the information to demonstrate that you understand the concept of negative feedback “
Answer:
Short paragraph:
Homeostatis is the process by which the body maintains a stable internal environment. The hypothalamus is a part of the brain that regulates many key body processes. It works to restore the system to its normal state when an internal change in one of these systems occurs.
Long paragraph:
The hypothalamus is a part of the brain that regulates many key body processes including internal body temperature, hunger, thirst, blood pressure, and daily (circadian) rhythms. When the brain receives signals from the body about an internal change in one of its systems, it works to restore the system to its normal state. For example, the normal internal temperature for the human body is approximately 98.6 degrees Fahrenheit. If the body temperature rises because of exercise, the body will try and cool itself off. This happens through coordination between the hypothalamus and the various body systems that are affected.

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.
one of the most common chromosomal disorders is ________ in which a baby has ________________.
Answer:
One of the most common chromosomal disorders is Down syndrome. Down syndrome happens when abnormal cell division results in extra genetic material from chromosome 21, too few chromosomes, or part of a chromosome may be missing. The difficulties of Down syndrome include hearing and vision weakness, weak auditory memory, fine motor skill impairment, short attention span with distractibility. Having Down syndrome can increase the risk of developing Alzheimer's disease. Having down syndrome can be associated with other health conditions such as ear infections, dental problems, endocrine problems, and seizures.

Biological molecules are large molecules made of various elements and compounds linked together. Proteins are composed of C, H, O, N, and S. Thus, option C is correct.
What are proteins?Proteins are considered macromolecules that are large in size and are polymers composed of various units of amino acids linked together by peptide bonds. They are involved in various activities and structural functions in the body.
The chains of various amino acids linked together make the protein molecule. The amino acids involved in the structure are composed of various elements that include, hydrogen, carbon, oxygen, nitrogen, and sulfur in various combinations. The amino acids contain amine, carboxylic acid, and other variable groups.
Therefore, option C. proteins are made of monomers of amino acids.

2. Discuss four types of evidence that support the theory of evolution.
HELP PLZ!!!
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.
