Answer: B
Explanation: Lysosomes are membrane-enclosed organelles that contain an array of enzymes capable of breaking down all types of biological polymers—proteins, nucleic acids, carbohydrates, and lipids.
The epidermis is a barrier to ultraviolet rays, blocking much of the cancer-causing radiation from reaching the nuclei of cells called keratinocytes.
<h3>
What is keratinocytes?</h3>
- Skin cells, also known as epidermal keratinocytes, are highly specialized epithelial cells created for a very specific purpose: separating the organism from its environment.
- Keratinocytes, which make up the majority of the epidermis, have a variety of functions that are crucial for skin restoration.
- They carry out the re-epithelialization process, in which keratinocytes move, multiply, and differentiate in order to reestablish the epidermal barrier.
- The majority of the epidermis's cells, known as keratinocytes, begin in the basal layer, manufacture keratin, and help to create the epidermal water barrier by producing and secreting lipids.
- A kind of stratified epithelium known as keratinized stratified squamous epithelium has many layers of squamous cells, or keratinocytes, with the superficial layer of cells being keratinized.
- The skin's epidermis is made up of this kind of epithelium.

Answer:
So 1 ml=1 cm^3, so 40ml is 40 cm^3
D= m/v
density = 30/40
Density of oil is 0.75 g/cm^3 (which is verified as oil is less dense than water hence floats on it)
Explanation:
An organism that obtains energy and nutrients by feeding on other organisms or their remains. A food web is a model of the feeding relationships between many different consumers and producers in an ecosystem. Without plants (the primary producers) consumers and decomposers would not be able to live. Producers always start every food chain. A consumer, also called a heterotroph, is an organism that cannot make its own food. It must eat producers or other organisms for energy.
The number of amino acids that will be in the polypeptide chain produced by the normal DNA or MRNA sequence is usually 30 amino acids. Although the number of amino acids depends on the function of the generated DNA or RNA. The types of amino acids also differ depending on the function.
