Answer:
Protection
Explanation:
The red arrow seems to be pointing to the membrane of bacteria cells. Probably the green structure also includes the cell wall.
Bacteria are a wide group of unicellular prokaryotic microorganisms with a simple structure and sized between 1 to 10 micrometers. These organisms lack a nucleus, nuclear membrane, and organelles. They only present plasmids and ribosomes. They have a cell membrane and a cell wall that protects the cell. Some of them can also show a capsule.
Membranes and cell walls delimitate and protect the cells from different extracellular factors that might damage them. The membrane constitutes a selectively permeable barrier that allows the free pass of only a few substances while it blocks others.

Explanation:
1) 72 of their chromosomes would be somatic and only 2 would be gametes. the number is always two as (normally) an organism will have either 2 X chromosomes (female) or an X and Y chromosome (male).
2) without genetic diversity, an entire species of an organism can go extinct from the same thing as none of them would have mutated any defenses and pass them off to their offspring.

A. Infrared light
B. Ultraviolet light
C. Microwaves
D. Radio waves
Answers
The electromagnetic wave that butterflies, hedgehogs, and many other animals can see is the ultraviolet light that is in Option B, as the ultraviolet light gives these animals a different perspective to visualize.
What role does UV light play in animals?Many animals can see the UV lights, and this is important as the flowers and fruits emit ultraviolet patterns that are invisible to humans but are seen by pollinators such as butterflies and help them find foods.
Hence, the electromagnetic wave that butterflies, hedgehogs, and many other animals can see is the ultraviolet light that is in Option B, as the ultraviolet light gives these animals a different perspective to visualize.

A neurone is a type of specialised animal cell.
(a) (i) Neurones develop from unspecialised cells.
State the name of these unspecialised cells.
Answers
Answer:
Stem cells
Explanation:
Stem cells are immature or unspecialized cells
Neurons develop from unspecialized cells and unspecialized cells are stem cells.
What are the functions of stem cells?
Embryonic stem cells are pluripotent stem cells derived from the inner cell mass of a blastocyst, an early-stage pre-implantation embryo. Human embryos reach the blastocyst stage 4–5 days post fertilization.
Stem cells are the body's raw materials — cells from which all other cells with specialized functions are generated. Under the right conditions in the body or a laboratory, stem cells divide to form more cells called daughter cells.
The cells of the bone marrow produce all of your healthy blood cells, including red blood cells, white blood cells, and platelets.

Answers
Answer:
Explanation:
This is because the new cell is produced asexually. Therefore the mutated cells are similar to the parent.
Asexual reproduction refers to the process where a parent plants reproduce or replicate new plants by itself and the new plants carries the same set of chromosomal numbers thereby been genetically identical to the parent.

Answer:
Flipper of a whale and bird's wing are homologous structures.
For more better explanation see below.
Explanation:
Flipper of Whale is homologus to the wing of a bird. Homologous organs - The structure which are similar in their morphology, anatomy, genetics and embryology, but dissimilar in their functions.
Flipper of whale and wing of bird has similar morphology and anatomy, but differ in their functions according to their species as well as the habitat where they live in.
A dolphin’s flipper, bird’s wing, cat’s leg, and the human arm are considered homologous structures. Whereas human beings have bones such as the humerus, ulna, radius, wrist bones, and fingers, these features appear as similar bones in form in the other animals. Bats, whales, and many other animals have very similar homologous structures, demonstrating that these creatures all had a common ancestor.
