Answer:
Variable trait in a population refers to the differences in genetic composition in individuals.
The variable trait is very common and necessary as we all have different parents and the process of meiosis which takes place in sex cells involves the parent passing only one set of chromosome to the offspring and producing four unique daughter cells.
The implication of this is that individuals will definitely have their own unique characteristics also.
This helps to promote diversity within the population and ensure people living in a particular region which involves special features or ability are able to cope as the traits are imbibed in such individual.

What is the best way to breed mice?
At what age can female mice breed?
Only answer if you have experience in this subject!
Will give brainiest!
Generally, putting one male with two females in a single cage will increase the chances of breeding. To prevent fighting, it's important that there's only one male in each cage. If you're not sure which mice are male, gently lift them up by the tail and look between their legs. Most mice reach sexual maturity (males and females) at 4-7 weeks of age. Younger mice generally produce smaller litters and therefore are not typically mated until they reach 6-8 weeks, of age. Mice that have been housed alone or in same-sex pairs will usually not breed successfully if they are older than 6-8 months.

Explanation:
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

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.

Match the characteristics with the phylum. Tongue-shaped structure called radula for grasping food spongin fibers or spicules for support fleshy lobe-like structure called parapodia Porifera arrowRight Molluska arrowRight Annelida
Answer:
A Tongue-shaped structure called radula for grasping food --> MolluscaFleshy lobe-like structure called parapodia --> AnnelidaSpongin fibers or spicules for support ---> PoriferaExplanation:
Radula: This is an organ used in feeding by mollusks. It constitutes a highly developed feeding organ. The radula has is conformed of small teeth-like structures located in rows. Lateral teeth vary in shape and size. The movements of the radula during feeding are complexes acting as a scratcher on the surface to get the food.
Parapodia: These are characteristic lateral appendixes that emerge and extend from each of the body segments of invertebrates such as polychaetes. The typical parapodium is a fleshy prolongation more or less laterally comprised and is composed of a superior branch (notopodium) and an inferior branch (parapodium).
Spicules: Sponges (Poriferous) skeleton is composed of calcium carbonate and siliceous micro-structures called spicules. Their morphology is so varied that it is used in taxonomy for identification and classification.
There are different kinds of spicules:
- Monoaxonic spicule: needle-shaped, straights or curves
- Tetraxonic spicules: they have four prolongations
- Triaxonic or Hexaxonic spicules
- Poliaxonic spicules
Two terms can be applied to any of these spicules kinds:
- Megaspicules: They are elongated and compose the main architecture of the sponge skeleton
- Microspicules: Variable in shape and size, with ancillary functions
Sponges have few predators because of the spicule structures and their high toxicity. Many of them are capable of perforating soft tissues and producing urticant substances.
