Answer:
chromosomes
Explanation:
Thread-like structures that are found in the nucleus of a cell that contains all DNA. Each chromosome is made of protein and a single molecule of DNA. Human cell nucleus contains 46 chromosomes or 23 pairs. Half of these chromosomes come from one parent and half come from the other parent.
Tropical Rainforest- >250 cm precipitation; 25c
Taiga- 101 cm precipitation - rain and snow; 15c
Tundra- no more than 25 cm precipitation in wettest month; <10c
Desert- <25 cm precipitation; 25c
These are the answers that were correct when i took this test. Hope this helps
1. Ask a question: He thought how traits passed from one generation to another.
2. Form a hypothesis: His hypothesis was "Each plat has two factors for a trait, one from each parent.
3. Test hypothesis: He grew pea plants to see what will happen.
4. Make and record observations: He discovered that one factor alone doesn't determine the expression of the trait in the pea plant.
<span>5. Conclusion: Traits in pea plants are inherited from the parent pea plants.</span>
Answer:
Explanation:
the advantages include:
disease and drought resistant crops that require fewer environmental resources for them to grow
higher yields harvested as the crops are not attacked by pests resulting in humans receiving more food as well as generating more money from the trading of their crops
increased supply of food at a cheaper life and the crops could have a longer shelf life
crops bound to be healthy as they ae not constantly treated by pesticides that could harm people
reduce the use of pesticides that might be a great move for the betterment of the food supply
they reduce the use of toxins that could harm the environment as well as the animals and people
disadvantages
unexpected or harmful genetic changes that could result in humans health being threatened
the process of genetically modifying the crops is quite expensive
due to the plants becoming pest resistant the pests are bound to have no food hence could die leading to some helpful pests such as beetles or ladybugs that actually benefit the environment going extinct
the production of genetically modified crops results in the disruption of biodiversity as you are favouring one specific organism hence resulting in the disruption of the natural gene flow
the crops are modified hence biotech foods may be a threat to the human health
Answer:
This is a type of breeding in which two organism having some special features are choosne to breed with each other to make a single organise which has both features accumulated
