Answer:
1. fragmentation- genetically identical
2. budding- genetically identical
3. haploid cells from two different mycelia fuse to form a zygote- genetically distinct
4. one hyphae creates spores through mitosis- genetically identical
Explanation:
1) Fragmentation is a form of asexual reproduction i.e. one parent, employed by certain organisms including fungi in which a FRAGMENT breaks off from the single parent to produce new cells. Since it is an asexual reproduction, the resulting cells will be GENETICALLY IDENTICAL.
2) Budding is another form of asexual reproduction that fungi undergoes e.g yeast. In the budding process, buds develop on the parent cell and later grow into mature cells that are GENETICALLY IDENTICAL to the parent cell.
3) In fungi, two different mycelia can produce haploid sex cells via the process of meiosis, which then fuse to produce a ZYGOTE. This method is a sexual means of reproduction. Hence, the zygote formed will be GENETICALLY DISTINCT from the parent.
4) Hyphae (threadlike filaments) of a fungi can via MITOTIC DIVISION produce spores, which then germinates under favorable conditions and grows into a new fungus. This new fungus cell is GENETICALLY IDENTICAL to the parent hyphae.
The first known single-celled organisms appeared on Earth about 3.5 billion years ago, roughly a billion years after Earth formed. More complex forms of life took longer to evolve, with the first multicellular animals not appearing until about 600 million years ago.
Answer:
The given muscles can be categorized into following categories:
Smooth muscles: These are involuntary muscles and non-striated muscles which are usually found within the walls of internal organs such as stomach, intestine, uterus et cetera.
Cardiac muscles: These are involuntary and striated muscles which are only associated with the heart.
Skeletal muscles: These are voluntary in nature and striated in structure. They are anchored to the bones with the help of tendons. They help in skeletal movement such as maintaining posture, locomotion et cetera. For example, hand muscles and neck muscles.
Answer:B
Explanation: Since there’s more snakes they’ll outweigh the rats and end up eating them until they’re gone unless the snake population decreases
