Answer:
A. Cellular respiration
C. Photosynthesis
Explanation:
There are two main processes occurs in the carbon cycle i.e. cellular respiration and photosynthesis. Plants absorb carbondioxide gas from the atmosphere through small openings called stomata. The carbondioxide enters the leaves and combine with water produces glucose and oxygen. Glucose is stored in different parts of plant whereas some oxygen is used by the plant and the remaining oxygen is releases in the atmosphere while on the other hand, in cellular respiration, glucose is broken down to produce energy in the form of ATP, carbondioxide gas and water.
The cellular machinery responsible for protein synthesis is the ribosomes.
Answer:
Option 1, a charged end and a noncharged end
Explanation:
Complete question
If a small droplet of ordinary fat is suspended in water, the fat molecules form a "ball of spaghetti" with no particular orientation. But if a droplet of phospholipid molecules is put in water, all the molecules point outward, toward the water. Phospholipids are forced into this orientation because phospholipids have _____
- a charged end and a noncharged end
- three fatty acid molecules, all pointing in different directions
- two fatty acid molecules pointing in different directions
- both a saturated fatty acid and an unsaturated fatty acid
- two charged ends
Solution
The structure of phospholipids consists of the following groups and molecules –
a) A glycerol molecule
b) Fatty acids (2 in numbers) – It is hydrophobic as it is uncharged and non polar in nature
c) Phosphate group (with alcohol) – It is hydrophilic as it is negatively charged and polar in nature.
When the phospholipids are placed in water, the molecule rearranges itself in a way that the hydrophobic head face inside and the hydrophilic head face outside thereby forming micelles.
Hence, option 1 is correct
B. Hydrogen Bonds connect nitrogenous bases together
The theory of Natural Selection was accepted after it got consensus from
scientists.
<h3>What is natural selection?</h3>
The theory of Natural selection defines the process in which individuals who adapts to their environment survives and reproduce more offspring.
- This theory was proposed by a scientist called Charles Darwin and Alfred Russel Wallace who also had the idea of evolution.
- This two scientist work together to publish a book on new evolutionary theory titled On the Origin of Species (1859). This is because they believed evolution occur through natural selection.
In this theory, organisms produce offspring but not all offspring survive this because they all struggle to live.
survival is based on survival of the fittest. some of those who survive can reproduce their kind while some do not grow to maturity and are loss.
Therefore, The theory of Natural Selection was accepted after it got consensus from scientists.
