I thinking the answer was for some genes, both alleles express together. Others combine to give an average phenotype....
Answer:Spectroscopy helps astronomers to determine the composition, temperature, density, and motion of an object.
Infrared spectroscopy helps to identify the atoms and molecules in the object.
The red shift or blue shift (Doppler Effect) in a spectral line tells how fast the object is receding from Earth or coming toward it.
The Doppler shift enables astronomers to discover extrasolar planets.
As a planet orbits its star, the star is alternately moving away from or toward us.
Astronomers can use the Doppler shifts to calculate the speed of the star and the mass of the planet that is tugging on it.
Explanation:
Endocytosis is a cellular process in which substances are brought into the cell. The material to be internalized is surrounded by an area of cell membrane, which then buds off inside the cell to form a vesicle containing the ingested material.
There are choices for this question namely:
1. Sterile
2. Reproductive
3. Both
4. Neither
The correct answer is that flowers are a collection of reproductive tissue produced by flowering plants (angiosperms). The flower is a reproductive organ of the plant. It is composed of the male organ (stamen) which produces the pollen and the female organ (ovary) which receives the pollen. Once the ovary receives the pollen either from the same plant or from another through pollination, the ovule (part of the ovary) will then become the seed and the ovary will become the fruit. The seed is the "embryo" of the plant wherein if planted, it will grow to a new plant.
Earth's crust is made of rock, and rock is made of natural substances called minerals. There are three main types of rock: sedimentary, igneous, and metamorphic rock. Each type is produced in different ways. The oldest rocks on Earth were formed about 3.8 billion years ago.
