Biology
1 answer:
serg [7]3 years ago
7 0

Answer:

Replication and Distribution of DNA during Mitosis. ... This process involves replication of the cell's chromosomes, segregation of the copied DNA, and splitting of the parent cell's cytoplasm. The outcome of binary fission is two new cells that are identical to the original cell.

Two scientists produce two different cladograms for the same group of organisms. Explain how the differences are possible.
S_A_V [24]

Answer:

Due to different grouping style

Explanation:

There are two modes of classifying an organism due to which two different cladogram are produced-  

A) When the organisms are grouped together on the basis of similarities shared by them – Such species are named based on the name of older species and the newly discovered species sharing similar traits are kept under older species thereby dropping its own name.  

B) In the second method, the minute differences are observed in species to group them into several branches arising from one parent organism.

just olya [345]

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.

A researcher investigates a recently discovered species of plant. The plant has vascular tissues and exhibits a sporophyte and a
Anna71 [15]

The plant contains vascular tissue and has an alternation of generation. But, it lacks seeds. So, the plant is a Pteridophyte.

  • Vascular tissues are absent in thallophytes and bryophytes. They are found in pteridophytes, gymnosperms and angiosperms.
  • The sporophyte and gametophyte generation is common in bryophytes and pteridophytes.
  • Seeds are produced in plants that come under the group gymnosperms and angiosperms. The presence of seeds is the main characteristic of these groups.
  • Thallophytes, bryophytes and pteridophytes lack seeds. The reproduction in plants that comes under these groups occurs with the help of spores.

Thus, the recently discovered species of the plant should be classified based on the presence of vascular tissues, gametophytes and sporophytes. As pteridophytes contain vascular tissues, sporophytes and gametophytes and lack seeds, the plant is a pteridophyte

From the question we are told

What is used during dissection what is used to feel

the tissue without using your hand to

touch the specimen?

A. Scalpel

B. Scissors

C. poker

D. T-pins

Generally Different tools have different applications to and uses during dissection.

  • Scalpel

This is a very sharp tool made of metal,Usually used to cut through specimens

  • Scissors

This a tool designed as a two metals sharpened at one end that faces each other, this tool aids in cutting

  • T-pins

This is a tool used commonly in dissections not to cut but rather to hold firmly in lace parts of specimen.This in a way stops the tool user from touching the specimen

Therefore
