Crossing over and the separation of duplicated homologous chromosomes in the first division produce genetic variation. true false User: The nuclear envelope disintegrates during _____.
metaphase
prophase
anaphase
telophase

Answers

Question 1. The statement that 'Crossing over and the separation of duplicated homologous chromosomes in the first division produce genetic variation' is true. Crossing over is the exchange of genetic material between homologous chromosomes that occurs during meiosis. As the result, the daughter cells are genetically different from mother cells. It is one of the ways to produce genetic variation. Question 2. The nuclear envelope disintegrates during prophase. This is the process that occurs at the beginning of mitosis. During prophase, the first phase of mitosis, the chromosomes condense and the nuclear envelope disintegrates. At the end of mitosis, the chromosomes will decondense and the nuclear envelope will re-form.
Prophase is the answer

Adaptation processes occur to help species survive and thrive in the ecological balance of life. 

Answer:

In the modern classification system birds are in a separate class from reptiles, but fossil evidence shows they have common ancestors.

Birds refer to the group of organisms which are endothermic in nature, have feathers, beaks, four-chambered heart, high metabolic rate, lay hard-shelled eggs and lightweight skeletons.  

In biological classification, they are classified under the class Aves.

Reptiles are four-limbed organisms which come under the class Reptilia.

However, biological and fossil evidence show that birds and reptiles shared common ancestors. It is believed that birds have evolved from the reptiles. Most of the scientists believe that birds are the specialized subgroup of theropod dinosaurs.

How might you model the relationship between a tomato plant and the hornworm caterpillar? Identify the components of the model including inputs and outputs

Answers

Answer:

Parasitism.

Explanation:

The relationship between a tomato plant and the hornworm caterpillar is parasitism because parasitism is a type of symbiotic relationship in which one organism get benefits and the other get harmed. We know that hornworm caterpillar feed on leaves and destroy the tomato crop. So it gets nutrients from tomato plant and the tomato plant is negatively affected. The input of this system is the vegetative part of tomato plant while the output is the conversion of hornworm caterpillar into a moth.
