Molecular Biology
This field of study deals with everything related to macromolecules, thus, what you will need for molecular biology would be something you could get proteins and nucleic acids from. Among the choices, the DNA of a pig and a calf would be the most helpful.
Comparative Anatomy
Comparative anatomy is a field of study that focuses on any similarities or differences between the anatomy or structure of different animals or species in general. Among the options, having the limb structure of a pig and a calf would allow you to practice the field since you have a structure to compare.
Developmental Biology
In this field, your concern would be how species grow and develop. For you to properly observe the growth and development, you must have the embryo of a pig and a calf. Therefore, among the options, this is the correct piece of evidence for this field.
IN SUMMARY:
Molecular Biology - Both DNA of a pig and a calf
Comparative Anatomy - Both limb structure of a pig and a calf
Developmental Biology - Embryo of a pig and a calf
(D) The gene that controls production of white blood cells.
Answer:
Colias Philodice
Explanation:
Following the dichotomous key:
The hindwings are rounded so it says to go to the 3. The options are orange with black wings or yellow with black wings. It has yellow on the wings so that means it is Colias Philodice.
Hope this helps!!! :)
If one parakeet is heterozygous, that means it has one dominant gene and one recessive gene (Rr). If the other is homozygous for white feathers, then it has two recessive genes (rr). Crossing these two in a punnet square gives you 50%.
Answer:
Greenhouse gases absorb radiation from the sun and re-radiate it back toward the <u>atmosphere,</u> which helps to maintain a normal range of <u>temperature</u> on Earth.
Greenhouse are glass house which are used to grow crops in regions exhibiting extreme cold temperatures and snow fall. The soil in these regions are frozen therefore, are not suitable for plant growth. These glass houses trap the sunlight which is used by the plants for photosynthesis and growth. Some gases like methane, carbon dioxide, carbon monoxide, sulphur and nitrogen dioxide are released into the atmosphere. These gases maintains the range of temperature of atmosphere.
