Answer:

Mistakes during mitosis during prophase leads to the production of daughter cells with too many or too few chromosomes, a feature known as aneuploidy. Nearly all aneuploidies that arise due to mistakes in meiosis or during early embryonic development are lethal, with the notable exception of trisomy 21 in humans.

Anton [14]

Answer:

The cilia in the upper respiratory tract move mucus down toward the pharynx whereas the cilia in the lower respiratory tract move them up toward the pharynx.

Explanation:

Through the internal nares, the air enters nasopharynx from the nasal cavity. This air has dust-laden mucus. The nasopharynx is lined with ciliated pseudostratified columnar epithelium. These cilia move the mucus down toward the most inferior part of the pharynx. The lining of the larynx inferior to the vocal folds is made up of ciliated pseudostratified columnar epithelium and have ciliated columnar cells, goblet cells, and basal cells.

The goblet cells serve to produce and secrete mucus. The mucus from goblet cells helps trap dust that was not removed in the upper passages. Therefore, the cilia in the upper respiratory tract move mucus and trapped particles down toward the pharynx whereas the cilia in the lower respiratory tract move them up toward the pharynx.

Natural selection relies on genetic variation. In any population of beetles, there are alleles for brown or green color. What ha

Savatey [412]

The correct order for natural selection can be summarized as:

1. Inherited variation: Individuals among the population exhibit inherited variation such as body color, body size, hair colors, voice properties, et cetera.

For example, the population of beetles: an equal number of green and brown beetles.

2. Competition: Organisms face the struggle for their survival.

For example, Natural habitat is in trees. Green leaves hide green beetles.

The brown beetles are noticed by birds in the area.

Birds eat brown beetles.

3. Selection: It leads to differential reproduction, that is, the organisms with adaptive traits tend to survive and reproduce more.

For example, green beetles reproduce in greater number than brown beetles.

4. Adaptation: The organisms with survival traits tend to survive more and pass their traits to the future generation.

For example, more green beetles survive than brown beetles.

5. Evolution: The change in allele frequency of the population takes place.

For example, beetle population changes from brown and green to mostly green beetles.

Thus, the correct order would be:

1. The population of beetles: an equal number of green and brown beetles.

2. Natural habitat is in trees. Green leaves hide green beetles.

3. The brown beetles are noticed by birds in the area.

4. Birds eat brown beetles.

5. Green beetles reproduce in greater number than brown beetles.

6. More green beetles survive than brown beetles.

7. Beetle population changes from brown and green to mostly green beetles

Correctly label the anatomical features of the muscle filament.

irina [24]

The labeled anatomical features of the muscle filament are attached as an image.

Muscle filament or Myofilaments are the two protein filaments of myofibrils in muscle cells. The two proteins are myosin and actin and are the contractile proteins involved in muscle contraction.

It has two filaments, a thick one made up mostly of myosin, and a thin one composed mostly of actin
Actin is a filament made up of protein that contributes to the contractile property of muscle. It is found in two forms, G-actin (monomeric globular actin) and F-actin (polymeric fibrous actin)

Tropomyosins are contractile proteins that regulate contraction in both muscle and non-muscle cells with help of myosin and actin filaments. It is present in animal cells.

A troponin complex is a group of three proteins, troponin T, troponin I, and troponin C, subunits located on the thin filament of the contractile apparatus.

Thus, the correct labeled anatomical features of the muscle filament is attached as an image.
