Number of chromosomes?
Sex of individual?
Normal? Yes or no.
If abnormal, what chromosome pair?
This is the picture of karyotype. Karyotype is a collection of a Individuals chromosome. Like pairs are separately represented from the unlike pairs, It is generally used to study the chromosomes and the abnormalities found in the number of chromosomes.
_____________________________________CHROMOSOMAL NUMBER 18:Every chromosomal pair seems fine, except the chromosomal pair number 18. Because as you ca see that it has 3 chromosomes instead of 2. This impairment in the chromosomal pair is called trisomy as it has 3 chromosomes.
_____________________________________TRISOMY 18:Trisomy 18 is also called Edwards syndrome. It is a chromosomal condition associated with abnormalities in more than one part of the body. Individuals with trisomy 18 often mature slowly than normal fetus before birth and they have lower weight at the time of birth as compared to the other children.
_____________________________________Best Regards!'Borz'There are 23 pairs of chromosomes in total, and the individual is male because it has one X and two Y chromosomes, but this individual is abnormal because of the trisomy in the 18th chromosome, as the 18th pair has three chromosomes.
What is the chromosomal abnormality?The chromosomal abnormality is caused by the mutation in the chromosome number and includes either the deletion of the chromosome or the addition of the chromosome in a homologous pair. The chromosomal abnormality has many negative consequences as well, some extra copies in the sex chromosome pair cause infertility, etc., while deletion causes life-threatening conditions.
Hence, there are 23 pairs of chromosomes in total, and the individual is male because it has one X and two Y chromosomes, but this individual is abnormal because of the trisomy in the 18th chromosome, as the 18th pair has three chromosomes.

After reading the paragraph below, answer the question that follows.Scientists interested in knowing the best way to restore an area after a temporary road was built through it completed a study comparing two treatments: (1) restoring the contour of an area so that there was no longer a depression or cut-through where the road was previously and (2) simply abandoning the area to allow vegetation to return on its own. They wanted to know whether either or both of these treatments would return the aboveground vegetation and the belowground soil properties to their original state, as seen in a similar area where there had never been a road.In this experiment, the area that had never had a road is useful to the experiment because:________________
Answer:
it acts as the control group in the experiment
Explanation:
The area that had never had a road is extremely useful because it acts as the control group in the experiment. The researchers can use this untouched area of land as a benchmark for the rest of the experiment. Once they implement both test scenarios on the pieces of road, they can then compare the results gathered from each study with the data gathered from the area that had never been a road in order to determine which option provides results that best compare to the original properties of the piece of area that has never been made into a road.
what do you think causes different phenotypes in organisms how does the phenotype depend on its genes (genotype)
Answer:
They difference in phenotypes is dependent on the genes. The more dominant gene will overpower a recessive gene, or if there are two recessive genes together, that will be the phenotype. When things are cross breaded they introduce different genotypes that allow for different looking phenotypes.
Example: Dominant blue flower (Bb) mixed with recessive yellow flower (bb)
B b
b Bb bb
b Bb bb
There is a 50/50 chance the offspring will be either blue or yellow
The differences in phenotypes are determined by genes. The more dominant gene will completely overwhelm a recessive gene, or if two recessive genes coexist, the phenotype will be that. When things are crossbred, unique genotypes are introduced, allowing for different-looking phenotypes.
What is phenotype?A "phenotype" is simply an observable trait. "Pheno" simply means "observe," and it derives from the same root as "phenomenon."
The differences in phenotypes are determined by genes. The more dominant gene will completely overwhelm a recessive gene, or if two recessive genes coexist, the phenotype will be that.
When things are crossbred, unique genotypes are introduced, allowing for different-looking phenotypes.
Thus, in this way, phenotype is dependent on genotype of the organism.

What is the role of lactase? which sugar does the act on in reaction?
Answer:
This enzyme helps to digest lactose, a sugar found in milk and other dairy products. Lactase is produced by cells that line the walls of the small intestine. ... Lactase functions at the brush border to break down lactose into smaller sugars called glucose and galactose for absorption.
Explanation:
Lactase is an enzyme produced by many organisms. It is located in the brush border of the small intestine of humans and other mammals. Lactase is essential to the complete digestion of whole milk; it breaks down lactose, a sugar which gives milk its sweetness.

6. D. It breaks down glucose to form ATP.
7. D. All autotrophs are producers
8. D. All 4 statements are correct.
9. False
10. False
Explanation:
The process of photosynthesis converts carbon dioxide and water into glucose and oxygen while the in the process of cellular respiration, glucose and oxygen are converted to water and carbon dioxide and ATP is formed.
In photosynthesis, glucose is formed while in cellular respiration ATP is formed. The process of forming ATP and glucose are ways in which energy is cycled and oxygen cycle occur in the atmosphere. Energy can not be recycled but it is rather used. Only green plants carry out photosynthesis. Autotrophs are known to be primary producers.

Explanation:
There are two different types of cell transportation. Which of the following requires energy?
a. Facilitated Diffusion
b. Active Transport
c. Osmosis
d. Simple Diffusion
please help :))
Answer:
The type of cellular transport that requires energy is active transport (option b).
Explanation:
Active transport —unlike passive transport— involves the passage of molecules or substances through the membrane against a concentration gradient, a process that requires the use of energy.
In the case of active transport the energy for the process comes from the ATP molecule and the mechanism for this to be possible is by means of an ATPase incorporated into the transporter.
The transport of glucose and the sodium-potassium and calcium pumps are examples of this type of transport.
The other options are not correct because simple diffusion, facilitated diffusion and osmosis are passive transport mechanisms that do not require the use of energy.
Recall what you know about nervous tissue to answer the following questions. Nervous tissue can generate and conduct ____ signals that control the body.
answer choices are:
chemical
electrical
thermal
Answer:
Nervous tissue can generate and conduct electrical signals that control the body.
Explanation:
The neuron is the specialized cell that provides function to nerve tissue. Given the structure of the neuron, this cell is capable of creating and conducting information in the form of electrical impulses or signals, by depolarizing its cell membrane and generating action potentials.
The information generated and transmitted by the neurons allows the nervous system to obtain internal and external information of the organism, as well as to control all the body functions.
The other options are not true because nerve tissue does not generate or conduct thermal or chemical signals to perform its function.

D. They have organelles that are surrounded by membranes.
Only animal cells have the process of obtaining energy through sugar. Plants on the other hand undergo photosynthesis, which uses sunlight instead of sugar.
Hope this helps! Please correct me if I'm wrong :)
Answer:
B. They do not have a rigid outermost layer.
Explanation:
Several organisms, including bacteria and eukaryotes are heterotrophs- this means that they obtain energy through breaking down organic molecules like sugar, and amino acids made by producers.
Animal cells are eukaryotic; all eukayoted may be single-celled, or multicellular, and contain a nucleus containing genetic material along with membrane-bound organelles in their cytoplasms. Animal cells do not contain rigid cell walls, unlike other eukaryotic cell types like plant cells.

a clams - a primary consumer
b. sardines - a primary consumer
c. sharks - a secondary consumer
d. kelp - a primary producer
The energy pyramid is a diagram that shows the flow of energy between trophic levels in an ecosystem. In an energy pyramid, the energy flows from producers to consumers.
The organisms that would most likely be found at top of the energy pyramid are sharks (secondary consumers).In an energy pyramid, the energy flows from producers (e.g., plants) to primary consumers (eg., herbivores). Subsequently, the energy then flows from primary consumers to secondary consumers (e.g., carnivores) and so successively.In an energy pyramid, the amount of available energy decreases as it moves through subsequent trophic levels.In conclusion, the organisms that would most likely be found at top of the energy pyramid are sharks (secondary consumers).
