Write about Cryptogams and Phanerogams
Explanation:
Cryptogams: Thallophytes, Bryophytes and Pteridophytes are called Cryptogams.Cryptogamae means having hidden reproductive organs.The reproductive organs in these plants are inconspicuous. Their naked embryos are called spores.Phanerogams: Gymnosperms and Angiosperms are Phanerogams.Phanerogams are the plants with well differentiated reproductive tissues.

A. Gametes
B. DNA
C. Meiosis
D. Mitosis
Answer:
B. DNA
Explanation:
DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person's body has the same DNA. The information in DNA is stored as a code made up of four chemical bases: adenine, guanine, cytosine, and thymine.

My cells have an organized nucleus. am usually made of many cells, but sometimes I can be single celled. I cannot make my own food, sol must eat. I can have one or two parents. Guess Who?
Answer:
Animalia
Explanation:
Read this paragraph from "How Water Loss Affects Biodiversity."
“When a region experiences a significant drought, many animals may die from lack of water and food. […] If tourism declines due to high wildlife casualties, then the locals who depend on income from tourism will lose their livelihood. People may then turn to farming to earn money, but crops require water to grow. This can place further strain on the water supply and worsen the original problem of the drought.”
What event can cause many animals to die from lack of water and food?
Answer:
Eggs and fried chicken with mentally stabled fries

3. Name the division of the peripheral nervous system that is activated in each of these
examples:
a. You are startled when a friend pulls a practical joke and spooks you with a loud sound.
b. You move your arms and legs to take an evening walk.
c. Your stomach makes a gurgling sound as it digests your lunch.
d. Feeling a little stressed? You take a few breaths to calm down.
e. You are at the line, waiting for you race to start, and your heart begins to pound.
A startle reflex (a), digestion (c), breathing (d) and heart pumping (e) are responses of the ANS, while arm/leg movement (b) is a response of the SNS. They are major divisions of the PNS.
The peripheral nervous system (PNS) serves to connect the central nervous system to different organs, limbs, and skin.
The PNS can be divided into Somatic Nervous System (SNS) and Autonomic Nervous System (ANS).
The Somatic Nervous System is responsible for controlling the voluntary movements of the body.
The Somatic Nervous System is responsible for regulating the involuntary movements (reflexes) of the body.
