Chromosomes are located within the nucleus of a cell.
Answer:
DNA (deoxyribonucleic acid)
Explanation:
In living beings (and in retroviruses), the genetic material is composed almost exclusively of deoxyribonucleic acid, known as double-stranded DNA.
DNA is an organic compound that contains genetic information that coordinates the development and the vital functions of the organisms of living beings.
That means that it determines the physical and physiological characteristics. In addition, it has the function of transmitting hereditary traits, such as, for example, hair color, eye color, and much other physical aspects.
In the case of DNA viruses, the material may be made of single-stranded DNA, while RNA viruses have RNAribonucleic acid as their genetic material.
(B) ridges
(C) trenches
(D) volcanoes
Answer:
the answer is d
Explanation:
Effects that are found at a divergent boundary between oceanic plates include: a submarine mountain range such as the Mid-Atlantic Ridge; volcanic activity in the form of fissure eruptions; shallow earthquake activity; creation of new seafloor and a widening ocean basin
Geographic isolation is the main cause of speciation.
Hybrid organisms always produce sterile offspring.
If a population is spread out over too large area, they may become extinct.
Speciation can only happen when a population has very low genetic diversity.
-----
A population of oak trees is separated by a large canyon. Which of the following is most likely to occur?
The two populations will show cospeciation.
The genetic variation between the two populations will increase.
Natural selection will cause one population to die, and the other to live.
Both populations will stop evolving.
-------
Choose ALL the answers that apply.
Extinction:
only happens above the species level
cannot happen to more than one species at a time
can be caused by habitat destruction
happens when a species or population dies out
-------
Which of the following statements is true?
Gene flow evens out genetic differences between populations.
Genetic drift increases the genetic differences between populations.
Natural selection, mutation, and genetic drift are random events.
The bottleneck effect increases the genetic diversity of a population.
---
A species is endangered if it _____.
no longer exists anywhere on earth
is in danger of becoming extinct
is not native the environment
has high genetic diversity
---
Genetic drift _____.
is a predictable event
increases genetic differences between populations
happens when random events change the genotype of a population
happens when well-adapted organisms survive and reproduce more often than poorly-adapted organisms
Answer: C, If a population is spread out over too large area, they may become extinct.
Answer:
A species is endangered if it is in danger of becoming extinct
Explanation:
a. dominant or the allele for the white flower
b. recessive to the allele for white flower color
c. codominant with the allele for the white flower color
d. incompletely dominant with the allele for the flower color
Answer:
c. codominant with the allele for the white flower color
Explanation:
i meant this one sorry
Based on typical patterns in plant genetics, the allele for purple flower color in the plant shown would likely be dominant over the allele for the white flower color. This is supported by Mendel's law of dominance and demonstrated through the Punnett square approach.
In relation to your question about the plant shown and the color of its flowers, the allele for purple flower color is likely dominant to the allele for the white flower color. To clarify, this is supported by Mendel's law of dominance, which indicates that in a heterozygote (a plant with one dominant and one recessive allele, like Vv), the dominant trait will be the one expressed.
Hence, as per the information from numerous studies, purple is often the dominant trait over white in flower color for many plant species, including peas.
Apart from that, from the Punnett square approach, when a homozygous dominant plant (VV) is crossed with a homozygous recessive (vv), all offspring in the first generation (F1) will be heterozygous (Vv) and will show the dominant trait, which in this case is the purple color.
In conclusion, based on this established genetic principle, if the plant you are referring to exhibits this common genetic pattern, then the allele for purple flower color would be dominant to the white flower color.
