Biology

Valentin [98]1 year ago
6 0

The main structure of epidermis is composed of 4 layers or strata. From bottom to top, these are:

  1. stratum basale attached to the basement membrane.
  2. two intermediate layers (stratum spinosum and stratum granulosum), and
  3. at the top is stratum corneum.
  4. There is also a 'thick skin' or the fifth stratum present at the feet and palm, known as stratum lucidum. It is present between the stratum corneum and the stratum granulosum.

Stratum basale is the deepest layer attached to the basement. Stratum spinosum makes the skin strong and flexible. Stratum granulosum prevents water loss from the body.  Stratum corneum acts as  a protective barrier on the outermost side of the skin. Stratum lucidum is made up of dead cells present only in thick skin.

devlian [24]

Answer:B) progress towards the replication fork.

Explanation:

Replication fork is a point on the parental DNA where the DNA is being unwound and separated; and the separated strands are being replicated. Synthesis of a new DNA strand occurs in a 5' -> 3' direction, as the DNA strand serving as the template is read from its 3' -> 5' direction. During replication, two strands of DNA are synthesized: The leading strand is synthesized continuously in the same direction as the replication fork movement while the lagging strand is synthesized discontinuously in the direction opposite to the direction of fork movement, that is, towards the replication fork. The lagging strand is synthesized in short fragments known as Okazaki fragments.

kobusy [5.1K]

Answer:

Air that is warmer is able to evaporate more water into the atmosphere. An air mass with more water vapor available to precipitate will naturally create more precipitation.

Explanation:

Most of South Florida has a tropical climate. There is a defined rainy season from May through October, when air mass thundershowers that build in the heat of the day drop heavy but brief summer rainfall. In some years the dry season becomes quite severe and water restrictions are imposed to conserve water.

sweet-ann [11.9K]

Answer:

Explanation:

What your asking isn't that clear but if you said 'producers' is a kind of plant that creates their own food and the process is called photosynthesis.

But at the same time your question says "this plant take in oxygen and release carbon dioxide during  just like animals and other living things" Im not sure that plants are the ones to take in oxygen and release carbon dioxide so....

I'm sorry if this didn't answer your question.

Which system covers and protects the tissues of the body from UV light and from infections due to bacteria and viruses?
dimulka [17.4K]

Answer:

integumentary system

Explanation:

The integumentary system is an organ system consisting of the skin, hair, nails, and exocrine glands. The skin is only a few millimeters thick yet is by far the largest organ in the body. The average person’s skin weighs 10 pounds and has a surface area of almost 20 square feet. Skin forms the body’s outer covering and forms a barrier to protect the body from chemicals, disease, UV light, and physical damage. Hair and nails extend from the skin to reinforce the skin and protect it from environmental.
