How are molecules organized

Biology
1 answer:
Ghella [55]3 years ago
7 0
<span>An atom consists of a positively-charged nucleus, consisting of various combinations of protons and neutrons, and negatively-charged electrons which move around the nucleus in distribution patterns called shells. In a neutral atom, the number of electrons is equal to the number of protons, but an ionized atom would have more or fewer electrons. Electrons are much less massive than protons or neutrons. 

(2) How are groups of atoms organized? 
Atoms bond together with other atoms to form molecules or can be part of a crystal lattice. </span>

If you turned a frog egg upside down, you would expect it to reorient relative to gravity because?
lianna [129]

If you turned a frog egg upside down, you would expect it to reorient relative to gravity because the dense yolk granules concentrated in the vegetal hemisphere of the egg respond to gravity.

The frog egg is very large as compared to the normal egg cell. It is unevenly distributed with a top dark colored pole called animal pole and a light yolky pole called a vegetal pole.

The vegetal pole is concentrated with the yolk that is present for providing the nourishment to the growing embryo. The animal pole is the one from where the sperm enters and the development of embryo take place.

As the vegetal pole is denser as compared to animal pole so it will respond to the gravity and reorient along the direction of gravity.

The type of inheritance that involves the partial expression of two different<br> alleles is called
belka [17]

Answer: Incomplete dominance

Explanation:

In incomplete dominance, both alleles are expressed but have become blended giving rise to a new trait with one also been more noticed than the other although both are expressed. For instance a red flower and a white flower are crossed, giving rise to a pink flower. As compared to codominance, both alleles are equally expressed and are equally dominant. For example, a white college crossed with a black hen giving rise to a black and white (checkered) chick.

The absence of which of these will not affect photosynthesis is - oxygen, Carbon dioxide, water, Chlorophyll, light. Give reason
In-s [12.5K]

Answer:

Oxygen

Explanation:

Oxygen is the by product of photolysis during photosynthesis whereby water molecules are split to form protons (H+ ions), electrons and oxygen (by product).

Oxygen is not needed during any of the reactions in photosynthesis and Calvin cycle and will not affect the rate of photosynthesis or possibility of photosynthesis occurring. However, it will affect the process of aerobic respiration instead.

Carbon dioxide is needed in carbon fixation during the Calvin cycle. Without it, 6 carbon sugars cannot be formed.

Water is needed for photolysis to produce protons (maintain the electrochemical gradient) and electrons (to replenish lost electrons)

Chlorophyll are pigments that harvest light energy to excite electrons produced from photolysis of water to be passed down the electron transport chain.

Light is needed as a source of energy to energise the electrons
