Korvikt [17]3 years ago
7 0

The triploids can not produce viable gametes,Triploid organisms are normally sterile as their lack of homologous chromosomes prevents  pairing during meiosis.

<h3>Why can't triploids reproduce?</h3>

Although polyploids are common among flora and some fauna, polyploidization often causes reproductive failure.

Triploids, in special , are depicted by the trials of chromosomal pairing and segregation during meiosis, which may cause aneuploid gametes and consequence in sterility.

Thus, option "B" is correct, triploids .

If you wanted to design a drug to prevent prokaryotic cells from attaching to substrates, which structure should the drug attack
galben [10]
Prokaryotic cell are unicellular organisms. They usually attached to substrate through their appendages. Their appendages are found on their cell wall. To prevent this organism from attaching to their substrate the drugs should primarily attack the cell wall of the prokaryote. This will prevent them form attaching and allowing harmful compounds in entering the cell.

Sharks and other predators do not normally eat plants however they do receive some energy from plants how is this possible
Leya [2.2K]
Animals get their energy by eating food.
Some animals eat plants. These are called herbivores.
They can also be known as primary consumers.
Carp is a herbivorous fish.


Nutrition – being able to get energy out of food ... Plants get their energy from the sun. ... Some animals eat both plants ... Predators. Predators eat other animals. Sharks eat fish so they are.

Shoot the Golgi Apparatus. Fill in the blanks: Golgi receives ANSWER containing ANSWER that were sent by the ANSWER Then it modi
loris [4]

Answer:

Golgi receives a vesicle containing newly synthesized proteins that were sent by the endoplasmatic reticulum. Then it modifies the proteins and sends them where they need to go.

Explanation:

Protein synthesis is initiated in the cytoplasm when mRNA meets a free ribosome, which is the primary structure for protein synthesis. They read the mRNA code and add the correct amino acid using transference RNA to build the protein. The synthesizing protein is driven to the rough endoplasmic reticulum and translocated to the lumen. Once there, the protein suffers a few modifications, one of them is folding to become functional. Once membrane proteins are folded in the interior of the endoplasmic reticulum, they are <u>packaged into vesicles</u> and <u>sent to the Golgi complex</u>, where it occurs the <em>final association of carbohydrates with proteins</em>. The Golgi complex <u>sends proteins to their different destinies</u>. Proteins destined to a certain place are packaged all together in the same vesicle and sent to the target organ. In the case of membrane proteins, they are packaged in vesicles and sent to the cell membrane where they get incrusted.

What are the phases in meiosis and explain
densk [106]

Cell division happens twice during meiosis. One starting cell can produce for gametes (eggs or sperm.) In each round of division, cells go through four phases called prophase, metaphase, anaphase, and telophase.

prophase During prophase the chromosomes become visible as paired chromatids and the nuclear envelope disappears. This phase includes reduction division, which is where the number of chromosomes is decreased from 46 (diploid) to 23 (haploid.)

metaphase This is where the 23 remaining chromosomes become attached to the spindle fibers.

anaphase During this phase, the chromosomes move away from each other to one or the other pole of the spindle fiber.

telophase In which the chromatids or chromosomes move to opposite ends of the cell and two nuclei are formed.

interphase This is a resting period.
