Pedigrees and karyotypes provide the means for individuals to identify their risks of genetic disorders. What can be observed on a karyotype but not on a pedigree?
family carriers of a genetic disorder
family history of a genetic disorder
risk of a genetic disorder in offspring
a visual image of a chromosomal defect
Answer:
D) a visual image of a chromosomal defect
Explanation:
The genetic disorders, or inheritance of traits, and abnormality in the chromosome can be studied through pedigree charts and karyotyping.
The correct answer is Option D, a visual image of a chromosomal defect.
The difference between karyotype and pedigree chart can be explained as:
Pedigree charts are the diagrammatic representation of the phenotypes of a particular gene or the lineage of the ancestors. The chart is used to study the inheritance of a trait or a disease. Karyotype refers to the collection of chromosomes, in which disorders or structures of chromosomes are studied. Karyotype provides visual damage or abnormality in the structure of chromosomes.
Thus, the correct answer is Option D.

Explain how green slugs can be considered both an autotroph and heterotroph
Answer: Green slugs can be considered both an autotroph and heterotrophs because they both are able produce their own food from raw materials and energy and they also consume fruits, vegetables, leaves, and other types of plants.
Explanation: The Yellow slug (Limacus flavus) is a greyish green to olive green slug, which may sometimes even have a yellowish brown colour. ... While the slug's body mucus is yellowish in colour, the sole mucus is colourless. Contrary to the adult slugs, the yellow slug's juveniles have a more greenish colour. Slugs will eat any kind of vegetation but prefer tender leaves. This means that particularly tender-leaved plants or seedlings are very vulnerable to slug damage. Slugs will also eat vegetables and fruits, causing unsightly damage to crops.

Cellular (aerobic) respiration takes place in the presence of and with the use of a certain element.
Which element is it?
Answer:
air
Explanation:
Oxygen and glucose are both reactants in the process of cellular respiration. The main product of cellular respiration is ATP; waste products include carbon dioxide and water.
Which statement best describes the end result of this process? a New molecules of mRNA are transcribed from the DNA molecule. b The new DNA molecules are made from opposite DNA strands so they are not identical. c A protein molecule is synthesized from the code in the DNA molecule. d Two new DNA molecules are formed, each identical to the original
Answer: c. A protein molecule is synthesized from the code in the DNA molecule.
Explanation: This shows the steps surrounding the central dogma of molecular biology stating that the genetic material, DNA contains the needed information and instructions for creating a protein, which are copied by RNAs. As such it follows that DNA is transcribed into RNAs which are in turn translated into proteins.

Francine is developing a model of the carbon cycle, which involves the movement of carbon among various Earth systems. She begins by drawing the diagram shown below.
Her friend Byron evaluates the model and suggests that she thicken the arrow leading from fossil fuels to the atmosphere. His reasoning is that fossil fuels are being burned at a much faster rate than natural processes are restoring them.
Label the model to show where it represents photosynthesis, cellular respiration, and the burning of carbon-containing materials.
Answer: in the upper box on the black arrows above the forest is photosynthesis and on the other one in that same circle is cellular respiration. Burning goes on the longest white arrow that goes from fossil fuels.
The labelling of the model is in the image.
The Model describe the carbon cycle in which there is a diagrammatical representation of how carbon is exchanged among the biosphere, hydrosphere, geosphere and atmosphere.What is a carbon cycle?
It is a biogeochemical cycle by which carbon is exchanged among various spheres of the Earth.
It shows the nature's way of reusing carbon atoms, into organism in the Earth and then back to the atmosphere over and over again.To know more about carbon cycle here

Why is it difficult for your body to return blood from your feet when you sit for too long?. Single choice. a. Blood has to travel a greater distance. B. Skeletal muscles are not squeezing the veins. c. Gravity makes the blood flow backward. d. The heart does not beat fast enough at rest.
Answer: Option C.
Gravity makes the blood flow backward
Explanation:
it difficult for your body to return blood from your feet when you sit for too long because gravity makes blood flow backward and this is because when you sit for long , it weakens the keg muscles because it is necessary for body movement so that blood will circulate or flow well. When the keg muscles becomes weak, it will slow blood flow in the leg and the force of gravity acting will make the blood flow backward and thus can cause a blood clot.

O B. Oxygen
• O C. Carbon
.
O D. Nitrogen
Answer:
C. Carbon
Explanation:
The central atom in an amino acid that all the groups connect to is a carbon atom.
Amino acids are monomeric units of proteins. They are bifunctional in that they have an amino group and a carboxyl group. These groups are attached to a carbon atom, α-carbon, in a molecule.
This is common to all amino-acids.

largely due to (constant unchanging conditions, a lack of natural predators, the variety of environments) throughout the ocean.
Answer:
high diversity, variety of environments
Explanation:
To this day, scientists are still discovering new marine animals. This is because of all of the different environments in the ocean, Some animals exist in tropical areas, others in freezing cold water.
