The translation is initiated as the
small ribosomal subunit muddles to the mRNA. Then
the tRNA having the methionine binds to the start codon, and the large ribosomal subunit binds to the insignificant one.
Finally, t<span>he start codon indicates the start of
translation.</span>
The uptake of carbon dioxide and the release of oxygen is essential for a plant to survive. Where and how does this gas exchange generally occur?
A. in all plant organs, as a result of cellular respiration
B. in the stems, to provide energy for lifting water
C. in the roots, to allow mineral absorption
D. in the leaves, as a result of photosynthesis
Answer D
Answer:
An invasive species thrives in its new ecosystem and out-competes native species. So, some factors are dominance, environment, predators, and resource availability.
Answer:
a. Her mother has zig-zag antennae.
b. Her brother has zig-zag antennae.
Explanation:
<u>Available data</u>:
- Antennae development ⇒ controlled by maternal effect
- Zig-zag coils are dominant
- Curly coils are recessive
- A female develops zig-zag coils
Maternal effect: Refers to the influence of the “environment provided by the mother” on the progeny phenotype. The mother´s genotype directly determines the progeny phenotype. Even though the progeny has a different genotype, it is irrelevant, as well as the father´s genotype or phenotype. This means that no matter what is the genotype of the offspring, all of them will express the same phenotype as their mother. The maternal effect is commonly seen in insects and might be seen in some mammals and plants.
So, if a female has zig-zag coils, this means that the mother also has zig-zag antennae and that all the brothers and sisters of this female ant have zig-zag antennae, independently of their genotype.
a. Her mother has zig-zag antennae ⇒ True. The trait is inherited from the mother.
b. Her brother has zig-zag antennae ⇒ True. The whole progeny will express sig-zag antennae.
c. This female carries the zig-zag allele ⇒ Not necessarily.
d. This female's offspring will have zig-zag antennae ⇒ Depends on it´s genotype
Answer:
Plant organ = Stem.
Explanation:
Stem holds the plant upright and connects the plant to its roots to keep it alive and have access to water and soil while the petals absorb the rays of sunlight.
