Answer:
b: many genes code for RNAs that function directly in the cell
Explanation:
<em>The central dogma</em> theory describes the basic framework for gene expression in living organisms. Genetic information from DNA is encoded or transcribed as RNA which then becomes translated as proteins.
The processes that take place for gene to be successfully expressed are;
- Replication
- Transcription
- Translation
<em>Replication</em> is a process whereby DNA makes a copy of itself to be distributed in daughter cells during cell division.
<em>Transcription</em> is the process whereby genetic information in DNA is encoded as RNAs. The RNAs are short-lived as they are quickly utilized in protein synthesis or <em>translation </em>process.
Hence, the RNAs do not function directly in the cells but mere intermediaries in the synthesis of proteins.
<em>The correct option is b.</em>
Answer:
The correct answer will be option-D
Explanation:
The evolution of vascular tissues in plants from non-vascular plants was an adaptive feature to survive in the terrestrial environment. The group of plants in which vascular tissues evolved and developed is the Pteridophytes which contained stellar organization of the vascular bundles.
The pteridophytes exhibited xylem and phloem which allows the rapid uptake of the water and nutrients from the soil which allowed the growth of the plant and since plants got enough water and nutrients from the soil, they adapted to grow tall so that they can maximize the output of photosynthesis in bright sunshine.
Thus, option-D is the correct answer.
The answer is true. The prosthetic group is present in
several components of the electron transport chain. The complexes one, two and
three can have a presence of prosthetic group in which is being referred to as the
iron sulfur clusters.
The correct matches are:
1. Sea level (0 m) - 100%
2. Mid-level elevation (4,500 m) - 57%
3. Peak (8,850 m) - 33%
The level of oxygen in the atmosphere depends a lot on the elevation. The smaller the elevation, the higher the oxygen level, and vice versa, the higher the elevation, the lower the oxygen level. So we have a situation in which the oxygen level is the highest at 0 elevation, or rather at sea level. As we go to higher elevations, let say to around 4,500 m, the oxygen level is significantly dropped, which makes it difficult for breathing. If we go even on higher elevation, like 8,850 m, than the oxygen level will much lower, and a human will need to undergo intense long training and also carry oxygen with him/her in order to survive.
Answer:
The herbivory by the white-tailed deer
Explanation:
The independent variable can be defined as the variable that who's values do not depend on those of another.
The independent variable in this case is the herbivory by the white-tailed deer which is divided into two categories.
The dependent variables is the response of the corn to the independent variable which are measurements to be taken as shown in the question; the height of the corn plants and the number of ears or corn each plant produces.
