Answer:
C. habitat fragmentation and preserve design.
Explanation:
The SLOSS debate involves issues relating to habitat fragmentation and preserve design.
TT and Tt are possible genotypes of a tall pea plant as the resulting phenotype of both possible genotypes result in a tall pea plant.
Yes.
<em>The sun emits all colors of the rainbow more or less evenly and in physics, we call this combination "white". That is why we can see so many different colors in the natural world under the illumination of sunlight. If sunlight were purely green, then everything outside would look green or dark.</em>
Answer:
C. Beak size is an inherited trait in the finch population under study.
D. Birds that could eat larger, tougher seeds survived and reproduced during the drought.
E. Beak size varies among the birds in the finch population under study.
Explanation:
The presence of genetic variations among the individuals of a population is required for natural selection to be operative. Natural selection targets the beneficial genetic variations present in the population. Natural selection refers to the differential reproductive and survival success of organisms of a population due to some beneficial genetic traits. These organisms with beneficial genetic traits are able to survive and leave more progeny under prevailing conditions.
If the natural selection has occurred in the ground finch population for the beak size, the beak size should be a genetic trait since natural selection works on genetic traits only. The finch population should have variations with respect to the beak size. The finches having the larger beak size that enabled them to feed on larger, tougher seeds should have higher survival and reproductive fitness during the drought.
Under these conditions, natural selection would favor the finches with larger beak size and would eventually result in an increase in the average beak size of the future generations.
Answer:
Medulla oblongata
Explanation:
Medulla oblongata is the part of hindbrain and have three vital centers located in it. The vital centers present in medulla are:
1. Cardiac center
2. respiratory center
3. and vasomotor center.
The cardiac center is also known as cardio inhibitory center and is involved in regulation of heart beat. The basic rhythm of breathing is under regulation of respiratory center while diameter of blood vessels is regulated by vasomotor center.
