How do mutations occur in the genetic code? This represents crossing over during meiosis.
a) During DNA replication, the original DNA strand GTC ACA GGC ATC is copied into complementary strand CAG CCG TAG. This is an example of deletion.
b)Mutations can only occur when passed on thorough reproduction. The majority of mutations are the result of exposure to mutagens.
c)A woman who has sickle cell anemia passes this disease on to her offspring. This means that the mutation for sickle cell anemia MUST occur in the woman’s gametes.
d)Mutations can be silent and not affect the organism that has them

Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers. Water is necessary for plants but only a small amount of water taken up by the roots is used for growth and metabolism. The remaining 97–99.5% is lost by transpiration and guttation.

Explanation:

A postdoctoral (commonly called postdoc) position is a temporary working position assigned by a particular institution/government agency to investigate questions referred to a particular research field/discipline (e.g., economy, molecular biology, immunology, politics, etc). In general, a postdoc is a 2-year position obtained after Ph.D. (i.e., Doctor of Philosophy) completion. This short-term research position is useful for professionals who require further training in a particular field/discipline, giving the individual more independence than in a Ph.D., which allows the development of technical skills and increases his/her interest in a particular research area.

Answer:

Medicinal plants are thought to be a rich source of ingredients that can be used in the development of pharmaceutical, non-pharmaceutical,, or synthetic drugs. Aside from that, these plants play an important role in the development of human cultures all over the world. Flowers are important in nature because they can feed insects, birds, livestock, and humans; they can provide natural remedies for humans and certain animals; and they can help in plant reproduction by attracting outside pollinators. Plants would be only green in the absence of flowers, and the earth would be a duller place.

crytogams - this type of vascular plant reproduces by spore.

phanerogams - this type of vascular plant reproduces from the seeds, hence also named as seed plants.

Angiosperms - this type of vascular plant reproduces flowers and fruits

Gymnosperms - this type of vascular plant reproduces cones and seeds only.

Answer:

Vascular plants are plants that have roots, stems, and leaves. They have a vascular system that is responsible for the distribution of water and nutrients. This system is made up of the xylem (responsible for distributing the raw sap to the leaves) and the phloem (responsible for transporting the processed sap to the rest of the plant). Within this group we have: pteridophytes (Many plants do not produce flowers. They are also known as cryptogams. They reproduce through spores) and spermatophytes (they are vascular plants that produce seeds and, therefore, are the most evolved).

Explanation:

Vascular plants are those that have a “corm” made up of root and stem (stem and leaves), as well as a conduction system made up of xylem and phloem for transporting water and photosynthates. Pteridophytes are vascular plants that do not produce seeds. Within the vascular plants they are the simplest plants at a structural level, since they do not have the complexity linked to the production of these seeds, which are what allow the sexual reproduction of plants. Spermatophytes are the vascular plants that produce seeds. These seeds generated by the flowers, when they fall to the ground after dispersing, germinate and give rise to a new plant. This presence of seeds that can be spread by the wind or by animals is what has allowed these plant species to colonize the world.

Together with stratigraphic principles, radiometric dating methods are used in geochronology to establish the geologic time scale. Among the best-known techniques are radiocarbon dating, potassium–argon dating and uranium–lead dating.

Answer:

Explanation:

The subconscious psychological meaning of a dream is its latent substance. This symbolically veiled content may be painful or traumatic. Therefore, option (B) is correct.

In Freudian dream analysis, content refers to both the Latent and manifest elements of a dream, or both the overt meaning of the dream and the dream as it is remembered. Dreams represent the uncontrollable mental events that occur during various stages of sleep.

The hidden psychological significance of a dream is its latent content. Because it could be distressing or traumatic, this content frequently makes symbolic appearances in disguise and contains things that are hidden from conscious awareness.
