Euglena are a unicellular organism. They are classified into the Kingdom Protista. They are then further classified into the Phylum<span> Euglenophyta. All euglena can make their own food by photosynthesis.</span>
The stimuli alter the activity of excitable sensory cells via Transduction.
Transduction is the method by which a virus transmit genetic material from one bacterium to another.
<h3>What is Transduction?</h3>
Transduction is defined as the genetic transfer from a donor cell to another recipient by a bacteriophage. The transduction consists of two stages:
-The formation of the transducer phage particle, the genetic material is introduced inside the capsid of a phage.

Answer:
The correct answer is : B. Carbon dioxide gas is produced as a by-product of alcohol fermentation but not lactic acid fermentation.
Explanation:
In t5he lactic fermentation, the end product is lactic acid whereas in Alcohol fermentation produces by-product carbon dioxide gas which makes it more suitable for baking.
Alcohol fermentation takes place the bread is made as gas is what puts tiny air bubbles within the dough of the bread and makes bread lighter consistency we are used to. Yeast helps in producing carbon dioxide by alcohol fermentation.
Question: Describe how a single amino acid substitution causes hemoglobin molecules to stick together. Use what you know about the structure of Hb and HbS, the properties of glutamic acid and valine, and how hydrophobicity causes molecules to behave in water.
Answer:
A Single amino acid must be polar to attract, just like water.
Explanation:
Sickle cell is an genetic illness and it is began by a alteration that arises in the beta sub units of the haemoglobin. Haemoglobin is a tetrameric protein made up of 2 alpha sub units and 2 beta sub units and it is the important part of the blood accountable for oxygen passage. Sickle cell is a illness that consequences from a replacement of a polar amino acid identified as glutamate with a non polar one valine at site six of the beta polypeptide component of haemoglobin. The replacement occurs as a consequence of a alteration in one of the bases in the beta-globin gene from adenine to thymine . As a outcome of this change, the beta polypeptide chains convert sticky in low oxygen circumstances since the valine sticks out of the chain and interrelates with neighboring non-polar amino acids.
Answer:
1. Light
2. production of large component from smaller components
Explanation:
In the given question, the meaning of the word Photo is light and the synthesis refers to the production and combining these words form photosynthesis. The literal meaning of photosynthesis will be the production of some compounds in the presence of light.
The word photosynthesis is used by the biologists to refer to a process taking place in the green plants which involve the light for the synthesis of energy-providing molecule glucose.
Thus, 1. The light and production of the large components are correct.
