How does energy move through living systems?
A. Energy can be created by organisms and can be passed on if it is not used by that organism
B. All of the energy is used up by organisms as they move, grow and reproduce so less energy is available for the next organism in the food chain
C. Energy is transformed and/or lost as heat as it passes from one organism to the next, but the total amount always stays the same
D. Energy is created during photosynthesis
Answer:energy is produced during photosynthesis. energy is used by the photosynthesiser or lost as heat, with the remainder available to the next organism in the food chain.

Describe how many genes and chromosomes can be found in the human body, and how they influence physical appearance and other traits.
I don’t really have an answer but I have an explanation
Explanation: In humans, each cell normally contains 23 pairs of chromosomes, for a total of 46. Twenty-two of these pairs, called autosomes, look the same in both males and females. These pairs of genes then determine certain physical features or traits.
Humans have 46 chromosomes and around 20,000-25,000 genes that determine physical appearance, behavior, and other traits.
What are chromosomes?The human body has 46 chromosomes, which are made up of long strands of DNA that contain the genetic information for an individual. These chromosomes are arranged in 23 pairs, with one chromosome from each pair inherited from each parent.
Each chromosome contains thousands of genes, which are segments of DNA that code for specific proteins that carry out various functions in the body. Genes play a key role in determining an individual's physical appearance, as well as other traits such as susceptibility to certain diseases and personality traits.
Inherited variations or mutations in these genes can lead to differences in physical appearance and traits between individuals. Additionally, environmental factors can also influence the expression of certain genes, further contributing to individual differences.

What kind of molecule forms from polysaccharide chains that are very
strong?
O A. Protein
B. Cellulose
C. Monosaccharide
D. Lipid
SUBMIT
PREVIOUS
Answer:
B. Cellulose
Explanation:
Polysaccharide are substances that contains many units of monomers called MONOSACCHARIDE. They are carbohydrate molecules consisting of very long chains of monosaccharides like glucose, galactose etc.
An example of molecule that forms from strong chains of polysaccharides is CELLULOSE, which consists of long chains of glucose units linked together by B-1,4-glycosidic bonds. Cellulose is the most abundant polysaccharide on Earth found in plant cell walls.

9. Doctors tested a patient to find out what molecules were in her cells. Her cells contained normal
levels of oxygen molecules, low levels of amino acid molecules, and low levels of glucose molecules
Will this patient be able to exercise normally?
a
Yes, as long as her cells have enough oxygen, her body will be able to exercise,
b
No, her cells need glucose to react with oxygen to release enough energy to exercise.
С
No, her cells need amino acids to react with oxygen to release enough energy to exercise.
d
No, her cells need glucose to react with amino acids to release enough energy to exercise.
Answer:
b. No, her cells need glucose to react with oxygen to release enough energy to exercise.
Explanation:
Living organisms are able to perform any of their day-to-day activities due to the release of energy in their individual cells. The process by which this energy is obtained by their cell is called CELLULAR RESPIRATION. Cellular respiration is the process whereby glucose (from digested food) is broken down in the presence of oxygen to yield energy in form of ATP. The general equation is as follows:
C6H12O6 (glucose) + 6O2 (oxygen) → 6CO2 + 6H2O + ATP
According to this question, a doctor is said to test a patient for the content of molecules in her cells. Her cells were found to contain normal levels of oxygen molecules, low levels of amino acid molecules, and low levels of glucose molecules. This patient will NOT BE ABLE to exercise normally because her cells need glucose in optimal amount to react with oxygen to release enough energy to exercise.
When will natural selection occur? A. When there is no competition B. When a population reaches carrying capacity C. When there are plenty of resources D. When there is no variation in a species
Answer:
B because when it hits its carry capacity its survival of the fittest to live
When a population reaches carrying capacity.
What is Natural selection?
An evolutionary mechanism is natural selection. Environment-adapted organisms have a higher chance of surviving and dispersing the genes that contributed to their success. Over time, this mechanism leads to the evolution and divergence of species.
One way to explain the millions of species that have existed on Earth is through natural selection.
The idea of evolution by natural selection is credited to Charles Darwin (1809-1882) and Alfred Russel Wallace (1823-1913), who co-wrote a paper on it in 1858.
Therefore, When a population reaches carrying capacity.

Explanation:
You have isolated a highly lethal toxin from an octopus that you have reason to believe binds with high affinity to the pore opening of a voltage-gated sodium channel. To determine the effect of toxin binding, you perform a _______ experiment.
Answer:
To determine the effect of toxin binding, you perform a Competitive Binding Experiment
Explanation:
Competitive binding experiments are very relevant when matters relating to cellular and or molecular toxicity are concerned.
They are used to determine the binding of a single concentration of labeled ligand in the presence of various concentrations of unlabeled ligand.
They are important because:
1. Validate a direct binding assay
2. Confirm whether or not a drug binds to the receptor
3. determine and explore how low-affinity drugs and receptors interact and it's resultant effects

Which type of brain wave originates in the central and pariental regions of the brain and is associated with normal sleeping
Answer:
Delta waves
Explanation:
This is because Delta waves are the slowest brain waves and they have they highest amplitude and these waves are responsible for normal sleep. They originated from Central and parental regions of the brain which is part of the cerebral cortex and they are refer to slow wave sleep. They can occur in the third stage of sleeping. They are deeply penetrated like drum beat and occur during deepest meditation and dreamless dream.
