Answer:
TT and Tt
Explanation:
Becuase the dominant allele can mask the recessive one, both TT and Tt are correct.
The question is incomplete as it does not have the options which are:
A) eight legs.
B) two pairs of antennae.
C) a sessile lifestyle.
D) an open circulatory system.
E) parapodia.
Answer:
D) an open circulatory system.
Explanation:
In the given question, the characteristics of an organism are given which are:
1. Exoskeleton- outer covering composed of cuticle
2. system of tubes for gas exchange- do not respire but has tubes called trachea from which the air diffuses
3. modified segmentation- segmented bodies
All these characteristics show that the organism belongs to the Arthropods group of animals.
The Arthropods since having trachea for the diffusion of gas, therefore, possess an open circulatory system in which blood does not flow in the vessels but the open cavities in the body.
Thus, Option-D is the correct answer.
Answer:
the correct answer is b
Explanation:
the human respiratory system is a series of organs responsible for taking in oxygen and expelling carbon dioxide. the primary organs of the respiratory system are the lungs, which carry out this exchange of gases as we breathe.
Answer:
Telophase
Explanation:
Cell division, particularly mitosis, involves five stages or phases.
1) Interphase
2) Prophase
3) Metaphase
4) Anaphase
5) Telophase
Telophase is the final stage of mitosis or meiosis during which the daughter chromosomes move towards opposite ends of the nuclear spindle.
The telophase stages is divided into early and late forms. During the early Telophase, the cell starts to constricts across the middle. During the late Telophase, the constriction continues.
* The nuclear membrane and nucleolus reform in each daughter cell.
* Spindle apparatus degenerates
* Chromosomes eventually regain their thread-like form and the cell returns to resting condition
