Answer:
Aren't they brothers and sisters
The statement 'plants have specialized tissues and organs and blue-green algae do not' identifies a characteristic that distinguishes algae from plants. They are different groups.
<h3>Planta and algae: similarities and differences</h3>
Plants and algae are autotrophic organisms that obtain their food by a process called photosynthesis.
Photosynthesis is a series of reactions by which plants and algae cells obtain simple carbohydrates by using the energy from the sun.
However, algae are unicellular organisms, whereas plants are multicellular organisms and are formed by tissues and organs.

Examples of positive and beneficial mutation:
- Antibiotic resistance by bacteria
- Almond tree gene mutation
- Humans immunity to HIV
Examples of negative and harmful mutation
- Cystic fibrosis
- Frame shift mutation
- Cancer
Examples of neutral mutation;
- Bovine and human insulin
- Silent point mutation
- Missense mutation
<h3>What are mutation?</h3>
Mutations are results from change in gene structures that leads to variations in form that can be transferred or passed down to generations. This is usually caused by alterations in the single base unit of DNAs by insertion, deletion or rearrangement of genes or chromosomes.
Positive and beneficial mutations result in retained from of adaptation like antibiotic resistance by bacteria, harmful mutation causes harm such as cancer, while neutral has little or no effect example, silent mutations.

The correct answer is option A, that is, the Earth is spinning on its axis.
The westerlies refer to the prevailing winds that blow from the west to the east in the mid-latitudes, that is, in between 10 and 60 degrees. The wind blows from the regions of higher pressure to the region of lower pressure, but it does not blow in a straight line.
This is generally because the Earth is rotating on its axis. The spin of the Earth makes winds to bend towards the right in the northern hemisphere and towards the left in the southern hemisphere. This is known as the Coriolis effect.
Answer:
<h2>Function as Waterproofing and works as a barrier to infection. </h2>
Explanation:
1. Keratinocytes are maintained at various stages of differentiation in the epidermis.
2. Keratinocytes are responsible for forming tight junctions with the nerves of the skin.
3. The outer layer of skin, the epidermis containing keratinocytes, which provides waterproofing and serves as a barrier to infection.
4. It is barrier to foreign particles and provide physical strength.
5. It helps in innate immune system.
